From Python to PureRAT: How Sneaky Cyber Crooks Pulled Off a High-Tech Heist!
A phishing campaign evolved from a simple Python-based infostealer to deploying PureRAT, a sophisticated remote access trojan. The attackers used clever tactics like DLL sideloading and process hollowing, and the operation was traced back to Vietnam. This highlights the need for defense-in-depth strategies to handle complex threats.

Hot Take:
Why did the hacker cross the road? To get to the other side of the firewall! It seems like they’re evolving faster than Pokémon, from a humble Python infostealer to the fully-fledged PureRAT. Guess we should be thankful they’re not using AI to train cyberattackers yet. Or are they?
Key Points:
- Phishing campaign morphed from a Python script to the PureRAT trojan.
- Attackers employed DLL sideloading and process hollowing to stay under the radar.
- Initial stages targeted credential theft via browsers.
- Campaign linked to Vietnamese actors, using Telegram for data exfiltration.
- Stressed the importance of multi-layered security defenses.
