The Key Recovery Attacks against Commercial White-box Cryptography Implementations

密鑰還原攻擊針對商用白箱加密之實作

intro.

White-box cryptography aims to protect cryptographic primitives and keys in software implementations even when the adversary has a full control to the execution environment and an access to the implementation of the cryptographic algorithm. It combines mathematical transformation with obfuscation techniques so it’s not just obfuscation on a data and a code level but actually algorithmic obfuscation.
In the white-box implementation, cryptographic keys are mathematically transformed so that never revealed in a plain form, even during execution of cryptographic algorithms. With such security in the place, it becomes extremely difficult for attackers to locate, modify, and extract the cryptographic keys. Although all current academic white-box implementations have been practically broken by various attacks including table-decomposition, power analysis attack, and fault injection attacks, There are no published reports of successful attacks against commercial white-box implementations to date. When I have assessed Commercial white box implementations to check if they were vulnerable to previous attacks, I found out that previous attacks failed to retrieve a secret key protected with the commercial white-box implementation. Consequently, I modified side channel attacks to be available in academic literature and succeeded in retrieving a secret key protected with the commercial white-box cryptography implementation. This is the first report that succeeded to recover secret key protected with commercial white-box implementation to the best of my knowledge in this industry. In this talk, I would like to share how to recover the key protected with commercial white-box implementation and give you some considerations when applying white-box cryptography to services more securely."

白箱加密旨在攻擊者完全控制執行環境和密碼演算法的情形下,仍能保護軟體密碼基元和密鑰;它將數學轉換與模糊處理技術相結合,因此不僅是混淆數據和代碼,實際上也混淆演算法。
白箱加密機制將密鑰進行數學轉換,即使在後續加密演算中也不會顯示為可讀形式;此一方式使得攻擊者很難找到、修改、抽離密鑰。雖然目前各種學術性白箱機制都或多或少被分解、分析、故障注入等攻擊方式破解,但迄今為止還沒有商用白箱加密機制被破解的報告。在評估用白箱加密機制是否會被前述攻擊破解中,本人發現前述攻擊方式未能破解被商用白箱加密機制保護的密鑰,因此我修改了學術文獻可見的側面通道攻擊方式,成功取得被商用白箱加密機制保護的密鑰。就我所知,這是本產業第一個成功截取被商用白箱加密機制保護之密鑰的實例。以下我將與各位分享如何截取被商用白箱加密機制保護之密鑰,並提出更安全應用白箱加密機制的幾個重點。
本人學經歷:本人目前任職於LINE集團安全部門資深安全工程師,主要從事於安全評估、安全架構設計、開發及其他安全相關的應用程式安全。我會分析程式、找出其中的弱點、鑽研安全相關的技術。最近幾年特別專注於白箱加密機制的實施、密碼分析方面的研究。

Building a Public RPZ Service to Protect the World's Consumers

打造公用 RPZ 服務守護世界

intro.

There are a variety of options when enterprises want to get protection for themselves. If you want to protect small offices or consumers, your choice is basically just to buy anti-virus. The problem is that until we solve the problem of most of the internet not being behind enterprises and thus unprotected, we still will face major outbreaks, DDoS, and risks from Bring-Your-Own-Devices (BYoD).
By using some basic open-source tools build in to DNS with Response Policy Zones (RPZ), it becomes possible to provide protection to the consumer internet space and begin to significantly disrupt criminal operations against the public.
This talk will cover building one of the worlds first public RPZ servers to provide service to CERTs and consumer ISPs to start to tackle the vast majority of the unsecured internet. Details on how to access and deploy the data for free from this service will be given as part of the talk.

當企業想要保護自身的時候,有非常多的選項。如果你想要保護消費者層面或是小型辦公室,你的選項基本上只需要買防毒軟體而已。問題是直到我們解決大部分的網際網路都不在大型企業中因而沒有受到保護的這件事之前,我們仍然要面對許多危機:DDoS,以及自帶裝置的風險等等。
藉由使用一些帶有 RPZ 的 DNS 的基本開源工具,我們將可能保護消費者的網際網路並開始明顯的干擾公眾的犯罪行為。
本演講將涵蓋建造世界第一個公用 RPZ 服務,以向 CERT 及消費者 ISP 等大部分不安全網路提供服務;其中也將包含如何免費存取此服務及從此服務發布資料等細節。

KRACK & ROCA

密鑰重置攻擊 & Coppersmith 演算法攻擊

intro.

KRACK (Key Reinstallation Attack) is a security weakness in WPA2 discovered by Mathy Vanhoef et al. Such weakness in WPA2 protocol design and implementations allows attackers within proximity to hijack the "encrypted" channel between a supplicant and a Wi-Fi AP. Both personal networks and enterprise networks are affected.
ROCA (The Return of Coppersmith's Attack) is a security vulnerability in an RSA firmware library discovered by Matus Nemec et al. The flawed library, from a major manufacturer of cryptographic hardware, is widely deployed in security tokens, smart cards, electronic ID cards, TPMs, etc. Since prime numbers generated by the flawed library have insufficient entropy and a specific structure, attackers can easily identify and factorize RSA public keys that were generated from affected devices.
In this talk, we will explain how KRACK and ROCA work and some important lessons we should learn from them.

KRACK (密鑰重置攻擊) 是 Mathy Vanhoef 等人發現的 WPA2 安全漏洞。此一 WPA2 協定的設計及實施弱點讓攻擊者可在近距離劫持請求者和 Wi-Fi AP 之間的「加密」通道,個人和企業網路都可能成為受害者。
ROCA (Coppersmith演算法攻擊) 是 Matus Nemec 等人發現的 RSA 安全漏洞。此一由主要加密硬件製造商所提供有缺陷的韌體庫,大量採用於安全符記、智慧卡、電子 ID 卡、TPM 等裝置;其所產生的質數熵值不足且具有特定結構,攻擊者可輕易辨識、猜測受影響設備生成的 RSA 公鑰。
本次發表將說明 KRACK 及 ROCA 的操作方式,以及幾個值得學習的課題。

Analyzing Bankbot, a Mobile Banking Botnet

分析行動網銀木馬 Bankbot

intro.

Maza-in, more known as Bankbot, is an Android banking Trojan that gained popularity with its release in an underground forum. At the beginning, its targets were mostly Russian and Ukranian entities, as well as payment processors, such as PayPal, but it quickly broadened its targets to different countries, especially European ones.
Despite having other Banking Trojans on the table such as Mazarbot and Marcher; Bankbot has made it into Google Play Store, not once, but a total of three times that we are aware of.
Having myself caught one of this Banking Trojans live in Google’s Play Store, I gained interest in studying how it bypassed Google security measures and made it through to the official Android store, and its different botnet components.
In this talk we are going to talk widely about Bankbot, covering many aspects of the thread. First, its behavior: The server-side structure of the botnet, how it communicates with the victim, as well as how to get around these communications, forcing the botnet to return us the list of affected entities.
Also, the Android component will be studied, taking into account the stealing techniques it uses and how it evolved, not only to target over Android banking applications but also browsers, based on the bookmarks installed. We'll have a brief overview of the libraries that some samples include, along with their functionality. The whole infection process will be described, from initial steps to credential theft.
Additionally, we will have an overview on the component that made it through the Google Bouncer and got published into the store, including a quick look to the different countries targeted by this family since the beginning of the attack.
Finally, we will learn how to identify the sample through Yara rules, as well as known changes done to the server file structure that helps us identify these samples.

Maza-in,也就是大家所熟知的 Bankbot,是一個 Android 上的網銀木馬;其在地下論壇一發布,就迅速聚集人氣。一開始的時候其目標大多在俄羅斯、烏克蘭以及像 PayPal 等支付平台;但它迅速將目標擴展到不同的國家,尤其是歐洲各國。
儘管檯面上還有其他像 Mazarbot 和 Marcher 等網銀木馬, Bankbot 不只一次成功打入了 Google 商店;光我們注意到的就有三次之多。
在我自己從 Google 商店中了這個網銀木馬後,我開始對它以及不同的殭屍網路元件如何繞過 Google 的安全檢查而成功上架發生興趣。
在本場演講中,我們將廣泛的討論 Bankbot 各方面的威脅。其中包含它的行為、殭屍網路的伺服器端架構、與被害者的溝通、以及如何利用它們傳回受影響的個體名單。

Respond Before Incident - Building Proactive Cyber Defense Capabilities

搶先事故反應:打造主動網路防禦能力

intro.

Historically, incident response has long been considered as an approach to managing the aftermath of security breaches when the incident occurs. Many organizations develop an IR process in the hopes of nothing will ever happens. However, while the tactics and procedures of threat attackers have evolved rapidly, and cost of conducting attacks has become much lower nowadays, it is time to realize that “You Will be Compromised”.
In this talk, we aim to discuss the question “Why traditional incident response is not enough?”
We will present a real-world case study showing how we helped an organization in Taiwan to mitigate the severe APT attacks from 4 attacker groups they were facing in the past 2 years. With this case, we will explain how we transform defense mode from passive to proactive, and share the methodology of threat hunting and elimination.

傳統上,事故反應長久來被認為是資安事件發生後的事後管理手段;許多組織發展出事故反應流程,並祈禱平安無事。然而,攻擊者的戰術和手段正與日俱進,發動攻擊的成本也日益降低;是時候面對「你一定會被攻破」的現實了。
在本演講中,我們將討論「為什麼傳統事故反應不夠?」的問題。
我們會使用真實世界的案例研究,示範我們如何幫助台灣的一個組職舒緩過去兩年中來自四個攻擊組織發動的進階持續性攻擊。在此案例中,我們將解釋我們如何從被動防禦轉變為主動防禦,並分享獵捕與消滅威脅的方法。

Open Source as Fuel of Recent APT

使用 Open Source 發動之 APT

intro.

Recently, there are so many APT attacks fueled by the usage of the open source tools.
We observed recent campaigns in 2017, and for those analysis we see that the use of open source tools are very common practice now. Such open source tools as, Metasploit Framework and Empire Powershell are widely used and some others are customized open source tools (to be exposed in the presentation) tailored to be an APT malware infection triggers or payloads.
For the targeted vectors, some are targeting Mac OS X and Windows platform of specific industries. In the recent campaigns, a part of code-signing certificates were stolen and recycled for further attacks in next targets on multiple platforms. And some others are targeting educational section with using Fileless attack via PowerShell.
In this presentation, we introduce our research details about these APTs, as well as TTPs (Tools, Techniques, and Procedures) with the flow as follows.
- Classification of the open source used for attacks:
There are plenty of open source tools used in APT attacks, one type of tools which are used for triggering exploitation in pre-infection, other tools are used for the remote access purpose on post-infection, and some more of the open source codes developed for the malicious activities were used for the APT cases infection. We will revel these in the presentation in some specific OS platforms.
- Real analysis APT cases presentation:
We will present the persistency triggered attack methods which are based from the real cases and events we investigated, we will present the flow of its front end attacks to exploitation, from exploitation to infection through to data harvesting methods, along with the source of tools and details of malicious activities detected.
- References:
In this point we will present list of the reference of the open source tools that is widely used for the recent APT attacks mentioned in the above two points

使用開放軟體進行 APT 攻擊的案例,在近年來有增加的趨勢。
2017 年的研究顯示,這種例行的攻擊非常普遍被採用。除了 Metasploit Framework 及 Empire Powershell 等廣獲採用外,某些其他還針對 APT 惡意軟體感染觸發及負載做了修改 (演講中會再進一步說明)。
這些受害者包括特定產業的目標 Mac OS X 及 Windows 平台。最近的攻擊中顯示一組程式碼簽章被盜之後,又再循環用於下一輪多重平台攻擊;另外一些則瞄準教育界,經由 PowerShell 進行 Fileless 攻擊。
以下簡報將說明我們對這些 ATP 及 TTP (工具、技術、程序) 研究的細節,大綱如下:
- 攻擊開源工具分類:
ATP 攻擊使用的開源工具很多,ATP 攻擊使用的開放軟體很多,感染前觸發、感染後遠端存取、以及開發開源程式碼進行的惡意動作則用於 APT 案例感染。簡報中將對這些工具在個別 OS 平台的現況進行說明。
- 真實 APT 案例分析:
我們將說明實際案例及事件調查所發現的持久性觸發攻擊方法,涵蓋從前端攻擊到利用的流程、從利用到蒐集數據的感染,以及所發現的來源與惡意行為詳細資料。
- 參考資料:
前述兩點範圍內近期 APT 攻擊常用的開放軟體參考清單。

The Age of Broken ATMs

那些年,他們搶的 ATM

intro.

We observed this year that the attacks against Automatic Teller Machines went from theoretical research and impressive show at a conference to a very practical method used by criminal groups to monetize their access to compromised networks within financial institutions. A number of cases that took place this year got loud attention in the media, but the attacker methods and exploitation varied from one case to another. In this presentation we examine several cases of ATM breaches including well known case that took place in Taiwan, but also Russia, Kyrgyzstan and other Central Asian countries as well as Spain and a number of other countries in Europe. We discuss attack vectors against ATM devices and known methods which the attackers utilize to abuse ATM machines for the purpose of either information collection or cash withdrawal. We also discuss some of the attack methods the attackers used to infiltrate the target organizations and compromise the devices. We dive deeper to understand the eco-system and the nature of the threat actors, discuss the skills and tools available on Black Market and the evolution of ATM threats.

這些年來我們觀察到駭客針對 ATM 的攻擊從學術理論和會議上的華麗展示,演變至犯罪集團透過此方式攻佔金融機構網路並而從中獲利。近年來眾多的攻擊案例出現在媒體閃光燈下,但駭客的攻擊手法也隨之進展。在本演講中,我們將展示這些年眾多的 ATM 攻擊手法,除了大家眾所皆知的台灣 ATM 事件,還包含俄羅斯、吉爾吉斯、 眾多中東國家、西班牙以及一些歐洲國家的攻擊案例。

Recent Cases of Cyber Terror from North Korea

案例分析:來自北韓的網路恐怖攻擊

intro.

In the past, suspected hacking attempts by North Korea appeared intended to cause social disruption or steal classified military or government data, but the focus seems to have shifted in recent years to raising foreign currency. N. Korea has tried hard to develop hacking capabilities as one way of earning money under the international strict sanctions imposed on them. An ATM hacking case is one of the examples.

以往,疑似來自北韓的網路攻擊,通常目的是造成社會信心瓦解,竊取國家軍事機密。但近年來攻擊似乎轉移至炒作外匯市場。北韓花費眾多心思發動網路攻擊賺取外匯以應對國際的經濟制裁。如同近年來 ATM 攻擊事件就是其中一例。

Threat Hunting, The New Way

威脅獵捕的新方法

intro.

Traditional methods of attack detection have failed us. Threat Hunting approaches the problem of attack detection from a new perspective, and seeks to find traces of attacker behavior with the assumption that networks are already compromised.
We’ll cover our approach for real world threat hunting at scale, the key datasets required, and why threat hunting is such an important new development for threat detection. By sharing a range of the real world attack scenarios we have personally encountered, we’ll show you how essential and effective it is to implement threat hunting scenarios into your detection strategy.
Finally, we’ll give you advice on how to start your own threat hunting journey within your organization.
By the end you’ll not only have an understanding of the concept of threat hunting, you’ll also know how to combine people, processes and technology to apply it yourself.

傳統偵測攻擊的方法並不可行。威脅獵捕的方法不只提供了一個偵測攻擊的新方向,也能在網路已經被入侵的前提下追蹤出攻擊者。
我們會以真實案例來探討為什麼威脅獵捕會是新型態偵測攻擊的方法。藉由真實世界我們所遇到的攻擊案例,將呈現為什麼威脅獵捕將會是必要且有效的攻擊偵測方式。
最後我們會建議你如何開始建立自己的威脅獵捕方法來保護組織。
你將不只能獲得威脅獵捕的基礎知識,還能瞭解如何整併人力、流程、技術來建置自己的威脅獵捕。

ICS/SCADA Cybersecurity and IT Cybersecurity: Comparing Apples and Oranges

張飛打岳飛:ICS/SCADA vs IT 網路安全

intro.

Stuxnet made headlines in the OT (Operational Technology) world back in 2010. It was a wake-up call to those who never really thought ICS (Industrial Control System) could be hacked, let alone causing severe damage to a nuclear plant in Iran.
Today, SCADA/ICS engineers are now expected to designed not only functional logic, safety logic but also system hardening for cybersecurity. Cybersecurity for ICS or OT poses different problems that are unlike that of Enterprise or IT Cybersecurity.
While Enterprise security prioritizes data in the order of CIA (Confidentiality, Integrity, Availability), ICS demands the reverse, i.e. AIC. Why is availability so important to ICS? Well, think of how important is your heart pumping to blood to various organs including your brain. Stop for a few seconds and the consequences could be fatal.
Every piece of data is processed in real-time. These 'data' consist of both sensor data and commands to output elements such as actuators, valves, motors and pumps etc.
That means latency is a key factor when intercepting such data to analyze becomes challenging. Typically, it cannot afford to be delayed more than a few milliseconds. And even if suspicious data is detected, it cannot be filtered out as any false positives could have dire consequences. Nothing shapes human behaviour to ignore 'cry wolf' any more than false alarms. Even to the point of muzzling or by-passing the security mechanism.
Another aspect of OT is in the area of Functional Safety whereby safety interlocks, Emergency Shutdown System (ESD or SIS) are designed with Safety PLC. Can hackers penetrate the SIS from Process Control System (PCS)? Can malware propagate from PCS to SIS? Can cybersecurity impact safety?
Given that OT is a different animal, how can we secure OT? Are there effective ways to protect ICS from Cyber-attacks? Tune in to find out the current industrial practices and the shape of things to come.

震網 (Stuxnet) 在 2010 年的時候成為了操作技術 (OT) 界的頭條新聞。它驚醒了那些以為工業控制系統 (ICS) 永遠不會被駭的人們,並造成了伊朗核電廠的重要損害。
時至今日, SCADA/ICS 工程師們被要求不只設計可用安全的邏輯,更要強化系統的資訊安全。ICS 或 OR 的資訊安全所遇到的問題與企業或 IT 的資訊安全是相當不同的。
企業對資料安全的要求有著保密、完整、可用 (CIA) 的順序,但 ICS 則要求相反的 AIC (可用、完整、保密)。為何可用性對 ICS 來說如此重要?這很簡單,想想你的心臟跳動,輸送血液到各器官和你的腦部;停個幾秒,後果就不堪設想。
每筆資料都會被即時處理。所謂的資料包含感應器的資料以及輸出到執行器、閥門、馬達和幫浦等的指令。
這表示延遲在擷取這些資料進行分析之中佔有關鍵的地位。一般來說,幾毫秒的延遲便是極限了。而且就算偵測到可疑資料,我們也不能將它濾掉,因為任何誤報都可能有危險的後果。這些假警報就像放羊的孩子一樣會讓我們忽略掉狼來了;即便我們的安全防線已經被突破了也一樣。
OT 的另一個層面就是關於功能安全,像是安全互鎖機制,以及利用安全 PLC 設計的緊急關閉系統 (ESD 或 SIS)。駭客有辦法從 PCS 滲透 SIS 嗎?惡意軟體可以從 PCS 感染到 SIS 嗎?網路安全可以影響實體安全嗎?
假如 OT 是一隻不同種的大象,那我們該怎麼把它放進冰箱?那我們跟怎麼確保 OT 的安全。是否存在更有效率的方式防禦針對 ICS 的網路攻擊?關注本場演說,一起了解現行的業界實作以及未來的趨勢。

Detecting the Intent, Not just the Technique: Changing the Mindset of Cyber Defense!

偵測入侵不只靠技術:換位思考網路安全防禦

intro.

As cyber threats have evolved we are witnessing the rise of new defenses. However, these defense layers often lead to new problems. A lack of true integration makes it almost impossible to see the bigger picture and truly understand the attack. As a result, customers face endless streams of unrelated data, creating alert fatigue and too many false positives. A major shift is required in the mindset of cyber security vendors so they can create solutions that truly confront & neutralize contemporary attackers and their advanced attack methods.
In this keynote we will discuss the shift that cyber security vendors should make in order to build products that are valuable not only as a silos but also as part of their customer's entire cyber security ecosystem. Finally, we will discuss new techniques and technologies that are required for success.

隨著網路威脅的升高,網路防禦也隨之提升,同時也帶來新的問題:欠缺整合性的認知,導致我們不但見樹不見林,更無法真正瞭解攻擊的本質。客戶因此面對無止境的無關數據、模糊的警報、查無實據的發現。網路安全廠商必須在心態上徹底改變,才能產生真正正面迎擊、消滅攻擊者及其先進攻擊武器的解決方案。
本演講將說明網路安全廠商在生產不止是客戶面對網路攻擊的堡壘,更是客戶整個網路安全生態體系一環的產品時所必須的換位思考;最後,也將討論成功所需的技術和科技。

Attacks on Mobile Networks: Evolving Hackers' Techniques and Defenders' Oversights

行動網路攻擊:進化的駭客技巧與防禦疏漏

intro.

The "walled garden" paradigm is outdated. Nearly all operators now admit that attackers have penetrated SS7 networks by exploiting a whole range of signaling network vulnerabilities.
Tracking subscriber location, obtaining call details, tapping, intercepting text messages that contain security codes are the harsh reality we live in. However, mobile operators do not sit back. They address these threats by configuring hardware in the best possible way, deploying SMS Home Routing solutions to protect confidential data and fight SMS spam and SS7 firewalls which currently offer the highest level of network protection against attackers.
But the real world is far from this rosy picture. Our researches alongside with security monitoring and audits show that attackers have learned how to skillfully bypass most of the known protection measures. In my presentation, I will address following issues:

  • What refined techniques and tricks do malefactors use;
  • What unusual attack scenarios we came across during security monitoring;
  • Methods found empirically for bypassing the protection mechanisms;
  • What security network specialists should pay special attention to in order to ensure SS7 network security and fight hackers effectively.

封閉平台的典範已經過時了;幾乎所有營運商現在都承認攻擊者已經藉由滲透一連串的訊號網路漏洞而打下了 SS7 網路。
追蹤實體位置、獲得通話細節、竊聽、攔截含有安全碼的文字簡訊;這些已都是我們生活中的現實。然而,電信營運商並不氣餒。他們藉由各種方式應對這些威脅:用最好的方式設定硬體、部署 SMS Home Routing 解決方案保護機密資料並對抗垃圾簡訊、還有 SS7 防火牆提供了目前最高等級的網路防護。
但光明的明天總是沒有等著我們。我們的研究人員利用安全監控與稽核發現攻擊者已經學會如何技巧性的繞過大部分的已知防護手段。在我的演講中,我會說明以下問題:

  • 攻擊者使用了哪些優化的技巧
  • 在安全監控中我們發現的異常攻擊情境
  • 從經驗中發現的繞過保護手段的方式
  • 網路安全專家應該特別注意的部分以確保 SS7 網路安全並有效的對抗駭客

All our Powers Combined: Connecting Academics, Engineers, and Hackers

結合我們的力量:學者、工程師、駭客

intro.

The field of information security is a conglomeration of three distinct communities: security engineers working in industry, academic researchers sequestered in their universities, and enthusiastic hackers battling it out on the CTF floor. These communities have different motivations, priorities and expectations, and the various disconnects between them often lead to misunderstanding, conflict, and twitter drama. While this is entertaining, it hampers progress in our field and allows security issues, that could be addressed through the collaboration of these three communities, to persist.
My name is Zardus, and I am an academic. However, due to the applied nature of my research and my extensive involvement in CTF, I have been observing (and often facilitating) interactions between the academic, industry, and enthusiast communities. I have seen our binary analysis framework, and other results of our research, applied in industry and in the CTF community. I have guided both CTFers and industry engineers in starting their academic careers, and I have guided students into industry and CTF. Through these experiences, I have built my own understanding of the different mindsets that these communities maintain, and developed hypotheses regarding the optimal ways that these communities can interact.
This talk will explore the commonalities, differences, and interactions of these communities. It’ll delve into the hopes and dreams of CTF enthusiasts, the aloofness of academics, and the no-nonsense attitudes of industry personnel. It’ll guide the audience through understanding not only the mindset of these groups, but will also provide a conceptual framework through which we can work together to advance the state of information security.

資訊安全領域有三個不同環節:產業的資安工程師、象牙塔裡的學術研究人員、在 CTF 賽場激情鬥爭的駭客群。這些社群擁有不同的動機、重點和期望,相互間的疏離使三者之間總是存在誤解、衝突和紛爭。雖然有趣但卻有害於這個領域的進步,使得原本可藉由三方合作解決的安全問題因此而不斷延續。
我叫 Zardus,雖然服務於學術界,但因所從事研究的性質及與 CTF 的廣泛接觸,有機會觀察 (促成) 產、學、業餘社群間的互動。我親眼看見我們的二元分析框架及其他的研究成果應用於產業和 CTF 社群。我帶領過 CTF 選手和產業工程師進入學術領域、學生進入產業和 CTF 社群。這些經驗使我對這些社群的心態有了自己的理解,形成使這些社群互動最佳方式的假設。
以下將探討這三個社群、其差異及之間的互動。我會深入分析 CTF 熱心人士的渴望及夢想、學者的超然態度,以及產業工作者講求實際的心態。一方面讓各位瞭解這些群組的心態,另一方面提出一個理論架構,讓三方合作提升資訊安全的水準。

The Bald Knight Rises

光頭騎士:黎明昇起

intro.

Kaspersky Lab has been tracking the XXMM (Trojan.Win32.Xxmm) malware family since January 2017. It's one of the cyber espionage targeting Japan.
This name comes from a database path (.pdb) that suggests “xxmm” as the original project name. To date we have observed more than 300 samples including core malware components, extra modules and related malware. The XXMM family seems to be mainly used against targets in Japan and South Korea. The actor uses around 50 compromised websites as C2s, with IP addresses based on the targeted countries.
Previously this attack was called after the malware it used, such as “Tick”, “BronzeButler”, “ShadowWali” or “Daserf”. The actor keeps changing its tools, so we decided to use a more generic name. We called this campaign “The Bald Knight” from the malware builder icon which was stolen from "The Dark Knight Rises" movie poster was altered by removing the protruding ears of the knight, leaving him with bald head.
This actor used several anti-research techniques such as in memory execution, second stage backdoor, anti-reversing, anti-AV, white-listing for target IPs on C2 server and stenography techniques. In this year, we already published about a unique anti-AV technique on the blogpost "Old Malware Tricks To Bypass Detection in the Age of Big Data" (https://securelist.com/old-malware-tricks-to-bypass-detection-in-the-age-of-big-data/78010/) about recent activities of this actor.
We believe that this cyber espionage campaign still have been attacking against to Japan seriously. Because, one of the infection vectors was a vulnerability found on the domestic management software used by the government, public-related offices and the government-affiliated organizations in Japan.
This presentation elucidates the method and strategy of "the Bald Knight Rises" campaign based on the result from the technical analysis of their cyber weapons, and introduces their recent activities.

卡巴斯基實驗室自 2017 年 1 月起便一直追蹤 XXMM (Trojan.Win32.Xxmm) 惡意程式家族:一個針對日本的網路間諜程式。
這個名稱的由來是由資料庫路徑中發現原始專案名稱可能為 ”xxmm”。至今日我們已經觀察到超過 300 個樣本,包含核心惡意程式元件、增益模組以及相關惡意程式。XXMM 家族似乎主要被用於針對日本及南韓的目標。攻擊者使用了大約 50 個像 C2 一樣和攻擊對象國家相同 IP 地區的被感染網站。
先前這類攻擊是以使用的惡意程式取名的,像是 ”Tick”、”BronzeButler”、“ShadowWali” 或 “Daserf” 等。攻擊者不停地改變工具,所以我們便決定使用更通用的名稱。因為惡意程式的圖示使用了電影「黑暗騎士」的圖,但將頭上的耳朵拿掉,使它變成一個光頭;所以我們便將其稱為「光頭騎士」。
攻擊者使用許多反研究技巧,像是記憶體內執行、第二階段後門、反逆向、反防毒程式、IP 白名單以及速記法等。在今年,我們已經發表了一篇關於此攻擊者近期發展的獨特反防毒程式的部落格文章「Old Malware Tricks To Bypass Detection in the Age of Big Data」。
我們相信這個網路間諜攻擊仍然持續的攻擊日本當中,因為其中一個感染方式是政府及相關單位所使用的國內管理軟體漏洞。

Improving Cybersecurity through Non-Technical Exercises and In-House Strategic Analysis: View from the Czech Republic

來自捷克的觀點:透過演習及內部戰略分析來增進資訊安全

intro.

Cyber exercises, particularly those aimed at the decision-making process, and in-house strategic analysis are two distinctive, but intertwined, elements of enhancing cybersecurity through measures that are non-technical in nature. The former presents the decision-makers with life-like situations to test reactions to an ensuing cybersecurity incident; the latter strives to provide them with the best available contextual intelligence to a cyber-incident and related technical analysis provided by CERT analysts. These two elements are seeking a common cause: well-informed decision-makers who can make the right call in response to a severe cyber-attack on critical information infrastructure or actions of hostile state actors in cyberspace.
Decisions come with political costs, which may incentivize risk-averse behavior even if the situation calls for bolder decision making, which is not necessarily unreasonable. From the decision-making perspective, any such move invokes legal and political considerations that might not always be apparent on the operational side of the incident response. Exercises that are designed to simulate the reality of a severe cyber incident need to address these challenges. In-house strategic analysis team’s role is to support technical teams/incident response teams by proactively informing the leadership about emerging threats in cyberspace. Furthermore, strategic analysts provide a timely contextual analysis that briefs the decision-maker on political, security, and legal elements surrounding an ongoing, or recently discovered cyber security incident.
The presenter will outline decision-making process and how exercises aim to make the process as bump-free as possible, present what is meant by strategic analysis in a context of a cyber-security organization, and introduce sets of legal and political issue that hinder a timely response to a cyber-attack with the help of selected case studies.

網路攻防演習,特別是那些著重於決策流程以及內部戰略分析的,是兩種獨特卻又糾結,利用非技術性方式增進網路安全的元素。前者代表了決策人員利用逼近現實的情境來測試面對接踵而至的網路安全事件的反應;後者則致力於提供面對網路安全事件的最佳適應能力,以及由 CERT 專家提供的相關技術分析。這兩個元素指向同一個目標:了解情況,在應對針對重要資訊設施或敵對網路攻擊行為等嚴重的網路攻防中,能做出正確決斷的決策人員。
但帶有政治代價的決策將可能導致盡力避免風險的行為,即便是需要更大膽決策的情況;這是不完全合理的。從決策的角度看來,任何觸及法律及政治考量的行動在事故回應的操作面上並不是全然顯而易見的。要設計模擬重大網路攻擊事件的演練時,這些挑戰也必須考慮進去。內部戰略分析團隊的角色是藉由主動通知網路中威脅來源的領導者,來支援技術團隊或事故反應小組。更甚者,戰略分析提供了有時序性的前後分析,能讓決策者了解圍繞在正進行中或近期發現的網路安全事件其政治、安全、及法律等各元素。
講者將概述決策流程以及演練如何讓流程盡可能順利、解釋在網路安全機構中戰略分析的意義、並藉由案例研究介紹在應對即時網路攻擊時可能成為法律或政治因素的障礙。

Respond Before Incident - Building Proactive Cyber Defense Capabilities

搶先事故反應:打造主動網路防禦能力

intro.

Historically, incident response has long been considered as an approach to managing the aftermath of security breaches when the incident occurs. Many organizations develop an IR process in the hopes of nothing will ever happens. However, while the tactics and procedures of threat attackers have evolved rapidly, and cost of conducting attacks has become much lower nowadays, it is time to realize that “You Will be Compromised”.
In this talk, we aim to discuss the question “Why traditional incident response is not enough?”
We will present a real-world case study showing how we helped an organization in Taiwan to mitigate the severe APT attacks from 4 attacker groups they were facing in the past 2 years. With this case, we will explain how we transform defense mode from passive to proactive, and share the methodology of threat hunting and elimination.

傳統上,事故反應長久來被認為是資安事件發生後的事後管理手段;許多組織發展出事故反應流程,並祈禱平安無事。然而,攻擊者的戰術和手段正與日俱進,發動攻擊的成本也日益降低;是時候面對「你一定會被攻破」的現實了。
在本演講中,我們將討論「為什麼傳統事故反應不夠?」的問題。
我們會使用真實世界的案例研究,示範我們如何幫助台灣的一個組職舒緩過去兩年中來自四個攻擊組織發動的進階持續性攻擊。在此案例中,我們將解釋我們如何從被動防禦轉變為主動防禦,並分享獵捕與消滅威脅的方法。

How to Construct a Sustainable Vulnerability Management Program

如何建造永續漏洞管理計畫

intro.

Whether you are ethical, unethical or halfway in between, vulnerabilities will never stop being found by you and your mates. Finding a 0day after months of hard work is definitely rewarding, but have we thought about the folks who works on the other side that have to protect keys and decide which one to patch? Well, this talk is about that. Heartbleed Vulnerability (CVE-2014-0160), Shellshock (CVE-2014-6271), Stagefright, POODLE Attack (CVE-2014-3566), Weak SSL/TLS Ciphers, and the good ole, Conficker (CVE-2008-4250), and… wait how about MS17-010? These six vulnerabilities are the most well-known, which one do you tell your IT admin teams to patch first? How do you prioritize them in a multiple billion dollar corporation with thousands of end points; do you know where they are; can you fix them all? Or even which vulnerability you should risk accept?
This talk is about build a sustainable vulnerability management program (VM) to answer these above and other vulnerability management questions, and how to build a program that can be scaled from small to large size company.

不論到道德與否,漏洞永遠都有可能被友軍發現。花費數個月努力挖掘漏洞的確是值得被獎勵的,但另一方面也有群人正努力地保護資料和決定如何修補漏洞。今天我們就是要從這個面向來探討。Heartbleed (CVE-2014-0160), Shellshock (CVE-2014-6271), Stagefright, POODLE Attack (CVE-2014-3566), Conficker (CVE-2008-4250) 等等漏洞。以及微軟 MS17-010 安全公告。以上六個都是廣為人知的漏洞。我們該如何跟 IT 人員討論第一個修補的漏洞該會是哪個?又該怎麼安排優先順序?你知道這些漏洞的細節?是該全部漏洞都修補?還是哪個漏洞針對你的公司環境並沒有那麼迫切需要修補?
本場次將討論如何建置永續漏洞管理計畫來解答以上的問題,並且有效的管理漏洞。以及該如何建立這套機制至各種規模的公司。

Threat Hunting, The New Way

威脅獵捕的新方法

intro.

Traditional methods of attack detection have failed us. Threat Hunting approaches the problem of attack detection from a new perspective, and seeks to find traces of attacker behavior with the assumption that networks are already compromised.
We’ll cover our approach for real world threat hunting at scale, the key datasets required, and why threat hunting is such an important new development for threat detection. By sharing a range of the real world attack scenarios we have personally encountered, we’ll show you how essential and effective it is to implement threat hunting scenarios into your detection strategy.
Finally, we’ll give you advice on how to start your own threat hunting journey within your organization.
By the end you’ll not only have an understanding of the concept of threat hunting, you’ll also know how to combine people, processes and technology to apply it yourself.

傳統偵測攻擊的方法並不可行。威脅獵捕的方法不只提供了一個偵測攻擊的新方向,也能在網路已經被入侵的前提下追蹤出攻擊者。
我們會以真實案例來探討為什麼威脅獵捕會是新型態偵測攻擊的方法。藉由真實世界我們所遇到的攻擊案例,將呈現為什麼威脅獵捕將會是必要且有效的攻擊偵測方式。
最後我們會建議你如何開始建立自己的威脅獵捕方法來保護組織。
你將不只能獲得威脅獵捕的基礎知識,還能瞭解如何整併人力、流程、技術來建置自己的威脅獵捕。

Cross-Platform Analysis of Indirect File Leaks in Android and iOS Applications

Android 及 iOS 應用程式中非直接檔案外洩的跨平台分析

intro.

Today, much of our sensitive information is stored inside mobile applications (apps), such as the browsing histories and chatting logs. To safeguard these privacy files, modern mobile systems, notably Android and iOS, use sandboxes to isolate apps' file zones from one another. However, I will show in my talk that these private files can still be leaked by indirectly exploiting components that are trusted by the victim apps. In particular, we devise new indirect file leak (IFL) attacks that exploit browser interfaces, command interpreters, and embedded app servers to leak data from very popular apps, such as Evernote and QQ. Unlike the previous attacks, we demonstrate that these IFLs can affect both Android and iOS. Moreover, our IFL methods allow an adversary to launch the attacks remotely, without implanting malicious apps in victim's smartphones. We finally compare the impacts of four different types of IFL attacks on Android and iOS, and propose several mitigation methods.

處在今日,越來越多敏感資料儲存在行動裝置 APP 中。例如瀏覽器歷史紀錄、聊天記錄。不管是 Android 還是 iOS 系統,為了保護這些隱私資訊,都會使用 sandbox 技術來確保各個 app 之間無法彼此讀寫資訊。然而,本場演講會示範如何透過直接破解手機 app 來偷取私密隱私資料。尤其是,我們將展示新的 indirect file leak (IFL) 攻擊瀏覽器、command interpreters 以及 app 後端 server 從某些熱門 app 中偷取資料。不同以往的攻擊手法 (ex. Evernote, QQ, etc…),我們將針對 iOS 及 Android 來示範 IFL 攻擊。此外 IFS 攻擊可從遠端發動,受害的行動裝置不需要安裝惡意的 app。最終來分析比較 IFS 及其他相關攻擊手法。

KRACK & ROCA

密鑰重置攻擊 & Coppersmith 演算法攻擊

intro.

KRACK (Key Reinstallation Attack) is a security weakness in WPA2 discovered by Mathy Vanhoef et al. Such weakness in WPA2 protocol design and implementations allows attackers within proximity to hijack the "encrypted" channel between a supplicant and a Wi-Fi AP. Both personal networks and enterprise networks are affected.
ROCA (The Return of Coppersmith's Attack) is a security vulnerability in an RSA firmware library discovered by Matus Nemec et al. The flawed library, from a major manufacturer of cryptographic hardware, is widely deployed in security tokens, smart cards, electronic ID cards, TPMs, etc. Since prime numbers generated by the flawed library have insufficient entropy and a specific structure, attackers can easily identify and factorize RSA public keys that were generated from affected devices.
In this talk, we will explain how KRACK and ROCA work and some important lessons we should learn from them.

KRACK (密鑰重置攻擊) 是 Mathy Vanhoef 等人發現的 WPA2 安全漏洞。此一 WPA2 協定的設計及實施弱點讓攻擊者可在近距離劫持請求者和 Wi-Fi AP 之間的「加密」通道,個人和企業網路都可能成為受害者。
ROCA (Coppersmith演算法攻擊) 是 Matus Nemec 等人發現的 RSA 安全漏洞。此一由主要加密硬件製造商所提供有缺陷的韌體庫,大量採用於安全符記、智慧卡、電子 ID 卡、TPM 等裝置;其所產生的質數熵值不足且具有特定結構,攻擊者可輕易辨識、猜測受影響設備生成的 RSA 公鑰。
本次發表將說明 KRACK 及 ROCA 的操作方式,以及幾個值得學習的課題。

The Age of Broken ATMs

那些年,他們搶的 ATM

intro.

We observed this year that the attacks against Automatic Teller Machines went from theoretical research and impressive show at a conference to a very practical method used by criminal groups to monetize their access to compromised networks within financial institutions. A number of cases that took place this year got loud attention in the media, but the attacker methods and exploitation varied from one case to another. In this presentation we examine several cases of ATM breaches including well known case that took place in Taiwan, but also Russia, Kyrgyzstan and other Central Asian countries as well as Spain and a number of other countries in Europe. We discuss attack vectors against ATM devices and known methods which the attackers utilize to abuse ATM machines for the purpose of either information collection or cash withdrawal. We also discuss some of the attack methods the attackers used to infiltrate the target organizations and compromise the devices. We dive deeper to understand the eco-system and the nature of the threat actors, discuss the skills and tools available on Black Market and the evolution of ATM threats.

這些年來我們觀察到駭客針對 ATM 的攻擊從學術理論和會議上的華麗展示,演變至犯罪集團透過此方式攻佔金融機構網路並而從中獲利。近年來眾多的攻擊案例出現在媒體閃光燈下,但駭客的攻擊手法也隨之進展。在本演講中,我們將展示這些年眾多的 ATM 攻擊手法,除了大家眾所皆知的台灣 ATM 事件,還包含俄羅斯、吉爾吉斯、 眾多中東國家、西班牙以及一些歐洲國家的攻擊案例。

Light Up The Korean DarkWeb

intro.

Four students from South Korea teamed up in order to dig into the Korean DarkWeb.
There is a number of publications about cyber underground including DarkWeb which covers the situation of the underground in many countries including Russia, the US, Germany, and Japan. But there is not so much information about cyber underground activities in the most connected country in the world, South Korea.
The team HGWT took on the challenge and discovered five DarkWeb forums in Korea as well as notorious activities in the Korean cyber underground part of the surface web.
In this talk, they will introduce specifics of the Korean cyber underground (including DarkWeb), share their approaches for investigations and discuss several case studies.

Team HGWT
The team HGWT (Dasom Kim, Sujin Lim, Sunghee Lim, Eunhee Jo) consists of four BoB students and is lead by two mentors in the digital forensics field, Nikolay Akatyev (VP of Engineering at Horangi Cyber Security) and Hyeon Yu (Professor at Korean Police Investigation Academy).
