Cobalt Strike Beaconを検知するVolatility Plugin(2018-07-31) - JPCERT/CC Eyes
JPCERT/CCでは、2017年7月頃から国内の組織に対して、Cobalt Strikeを悪用した攻撃が行われていることを確認しています。Cobalt Strikeは、標的型攻撃を模倣することができる商用製品[1]であり、インシデント対応演習などで利用されますが、攻撃者に悪用されるケースもあります。Cobalt Strikeを悪用する攻撃グループや、Cobalt Strikeの詳細については、株式会社ラック[2]やFireEye[3]、Cybereason[4]が公開している情報に詳しく記載されていますので、そちらをご覧ください。 Cobalt Strikeは、ダウンローダーとなるWord文書などを用いて、本体となるペイロード(Cobalt Strike Beacon)をダウンロードさせることで、メモリ上で実行されます。 Cobalt Strike Beaconはディスク上には保存されな
Fast Malware Triage using openioc_scan Volatility Plugin - CCI
Last year, I proposed “volatile Indicators of Compromise (IOCs)” based on RAM evidence only at SANS DFIR Summit. We can detect malware using them faster than using disk-evidence-based IOCs. Besides, we can define indicators based on not only metadata (e.g., file path) but also malware function (e.g., code injection sign, imported functions and unpacked codes). The IOCs are described according to O
Memory Forensics: How to Pull Passwords from a Memory Dump
Last time, we talked about a quick and easy way to get a memory dump on a Windows based PC. This time, we will cover pulling passwords out of captured memory files. Several programs exist for memory analysis, we will be using “Volatility” from Volatile Systems. If you are performing your analysis on a Windows system I recommend downloading the stand alone .exe version. If you don’t then you will a
Volatility 2.0 Plugin Vscan
I came across a program the other day that is very powerful when it comes to IR (Incident Response). So wanting to learn more about the platform I dived right in and decided to create a plugin. What if you could automatically carve out a file from a memory image and submit said carving to an online virus scanning service? That’d be awesome and make for quick work to triage any memory dumps you
Stuxnet's Footprint in Memory with Volatility 2.0
In this blog post, we'll examine Stuxnet's footprint in memory using Volatility 2.0. A talk was given at Open Memory Forensics Workshop on this topic (see the online Prezi) and the details will be shared here for anyone who missed it. I picked this topic for two reasons. First, Stuxnet modifies an infected system in such ways that are perfect for showing off many of the new capabilities in Volatil
Detecting/Memory Forging Attempt by a Rootkit
In my previous post on analyzing threads, I hinted that there would be a separate discussion regarding Rachit Mathur's Memory Forging Attempt By A Rootkit article. Well, here it is! In his blog, Rachit described a malware sample that prevented live anti-rootkit tools from detecting the malware's IRP hooks. To summarize the malware's technique, it did the following: 1) Hook KiDebugRoutine (see skap
Investigating Windows Threads with Volatility
There are various ways of finding objects and data structures in a memory dump. Two of the popular ways include list traversal (or pointer traversal) and pool scanning. Depending on which plugin you use, Volatility allows you to enumerate processes, sockets, connections, and kernel modules using both of these methods. Regarding threads, however, there is only one plugin, named thrdscan2, which use
