Hiding in the Tunnels: Unmasking the New Stealthy BPFDoor Variants

This is Rapid7's whitepaper discussing BPFDoor variants. Advanced persistent threats APTs are locked in a continuous arms race with network defenders. As static indicators of compromise IoCs for the notorious BPFDoor malware became widely deployed by security vendors, the threat actors went back ...

Stealthy and Adjustable Text-Guided Backdoor Attacks on Multimodal Pretrained Models

Multimodal pretrained models are vulnerable to backdoor attacks, yet most existing methods rely on visual or multimodal triggers, which are impractical since visually embedded triggers rarely occur in real-world data. To overcome this limitation, we propose a novel Text-Guided Backdoor TGB attack...
