RUSTSEC-2026-0102 `microsoftsystem64` was removed from crates.io for malicious code

microsoftsystem64 installs a hardcoded SSH authorizedkeys entry persistence/backdoor and scans for sensitive files .env, credential-like JSON names, keyword-matching docs, reads their contents, base64-encodes where needed, and exfiltrates everything to a remote server via HTTP. It also packages a...

OpenAI Revokes macOS App Certificate After Malicious Axios Supply Chain Incident

OpenAI revealed a GitHub Actions workflow used to sign its macOS apps led to the download of the malicious Axios library on March 31, but noted that no user data or internal system was compromised. "Out of an abundance of caution, we are taking steps to protect the process that certifies our macO...

CLIP-Inspector: Model-Level Backdoor Detection for Prompt-Tuned CLIP Via OOD Trigger Inversion

Organisations with limited data and computational resources increasingly outsource model training to Machine Learning as a Service MLaaS providers, who adapt vision-language models VLMs such as CLIP to downstream tasks via prompt tuning rather than training from scratch. This semi-honest setting...

BadSkill: Backdoor Attacks on Agent Skills Via Model-In-Skill Poisoning

Agent ecosystems increasingly rely on installable skills to extend functionality, and some skills bundle learned model artifacts as part of their execution logic. This creates a supply-chain risk that is not captured by prompt injection or ordinary plugin misuse: a third-party skill may appear...

Follow My Eyes: Backdoor Attacks on VLM-Based Scanpath Prediction

Scanpath prediction models forecast the sequence and timing of human fixations during visual search, driving foveated rendering and attention-based interaction in mobile systems where their integrity is a first-class security concern. We present the first study of backdoor attacks against VLM-bas...

SkillTrojan: Backdoor Attacks on Skill-Based Agent Systems

Skill-based agent systems tackle complex tasks by composing reusable skills, improving modularity and scalability while introducing a largely unexamined security attack surface. We propose SkillTrojan, a backdoor attack that targets skill implementations rather than model parameters or training...

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...
