Is TrickBot Indestructible?
Since the past takedown attempt in November 2020, TrickBot malware has not only re-emerged, its operators have been launching newer versions from time to time. They have recently released a more persistent version of the malware.

- The newest version, numbered 100003 by its developers, has been numbered backward in comparison with the previous versions 1000512 and 1000513.
- This version contains several enhancements, including a modified persistence mechanism and a creative mutex naming algorithm.
- However, it has the same process hollowing code injection tactic, bot configuration scheme with task name modification with a random twist, and the same compromise checks.
TrickBot lives on
TrickBot has nursed itself to its full potential and is evolving continuously.
- In December, Subway UK’s marketing system was hacked to distribute TrickBot-laden (TrickBot v100) phishing emails.
- In the same month, the TrickBot malware was observed with a functionality, designed to inspect the UEFI/BIOS firmware of targeted devices.
