Of course, I couldn't start this thread without talking about this project we started in 2015. Unprotect Project is a database about Malware Evasion techniques with code snippets and detection rules. cf: @DarkCoderSc
Living off the land refers to the use of dual-use tools, which are either already installed in the victims' environment, or are admin, forensic or system tools used maliciously.
DLL hijacking is a common technique used by malware. This project provides a list of DLL Hijacking candidates. A mapping between DLLs and vulnerable executables can be searched via this website. cf: @Wietze
Privilege escalation is often used by malware to gain more access in an infected machine. This list keeps track of privilege escalation resources. cf: @m0nadlabs
During execution malware will leave track on the system that can be retrieve in Windows events. This list keeps tracks of resources related to Event ID analysis. cf: @stuhlonsky
Analyzing data leaks is a very interesting Intel challenge, especially when you’re dealing with a foreign language 🤓
The I-SOON leak, which contains mostly PNG files of screenshots of documents, is a good example 🔎
Last night, I created a Notebook to automatically process and analyze the data to speed up your investigation.
Here is my process 👇 🧵
If you don't want to read the thread, you can directly jump to the notebook here:
#infosec #isoon #leak #threatintel #llm #python #jupyterjupyter.securitybreak.io/ISOON_DataLeak…
As always, when analyzing new data, check out the structures and formats, and spend time to understand what kind of data you're dealing with. THIS is crucial!🔍
With Python, you can easily peek into the content 💻
Here I created two simple chart to visualize the repartition of the data:
📢I recently investigated a campaign targeting the cryptocurrency industry. I wrote a detailed report that includes TTP, IOC and more. Here is a thread about this attack! 🧵👇
The attack started on Telegram to identify the targets, then they deployed a weaponized Excel document which finally delivered the final backdoor through multiple mechanisms. ☠☠️ #infosec#malware#backdoor
🧐To identify the targets, the threat actor sought out members of cryptocurrency investment groups on Telegram.
👀They created fake profiles using details from employees of the company OKX. #infosec#Cryptocurency
Visualizing #cybersecurity concepts can be a great way to learn more about specific tools, methodologies, and techniques! Here is a thread that shows 6 useful infographics on threat intelligence and related topics!🧵👇#infosec#threatintel
1⃣ - Practical Threat Intel
2⃣ - Tactics, Techniques and Procedures is an important concept to understand when you are working on threat intelligence to understand the capabilities of threat actors! 🤓 #Infosec#ttp
3⃣ - Mitre ATT&CK Matrix is became one of the references to classify and categorize attackers' TTPs! ☠️ #cybersecurity
The #sunburst case is interesting and demonstrates how threat actors can rely on evasion techniques or defense evasion to spy on or make damage. #UnprotectProject Thread 👇
First of all, the use of the supply chain attack made the attack super stealthy and difficult to detect. This is another red flag to increase and improve trust with partners and suppliers, although it is difficult to resolve.
#Sunburst uses the TrackProcesses() function to verify blacklisted processes and services. If an item in the blacklist is found, the loop is terminated.
