Beware: The Sneaky World of Fileless Malware and Alternate Data Streams!
Ever wondered how sneaky malware hides in plain sight? Meet Alternate Data Streams, NTFS’s not-so-secret weapon. It’s like a magician’s pocket – storing extra data without leaving a trace. Just remember, if your computer starts acting like it’s got a mind of its own, maybe it’s time to check for those pesky ADS.
Hot Take:
In a world where malware is going all ‘filess’ and trying to leave no trace, Alternate Data Streams (ADS) are the sneaky little hobbits of the NTFS world, hiding in plain sight and keeping their malicious secrets well tucked away. Who knew malware could be so… literary?
Key Points:
- Alternate Data Streams (ADS) in NTFS can hide metadata along with main file content.
- A Python keylogger uses ADS to stealthily store keystrokes and clipboard data.
- The script sets file attributes to hidden using Windows API.
- The keylogger lacks an exfiltration mechanism—perhaps a team player in a larger scheme?
- PowerShell can be used to detect ADS on your system.
