Causal Foundation Models

A paper introduces causal foundation models (CFMs): pretrained networks that estimate treatment effects on new datasets via in-context learning without fine-tuning.

Causal foundation models (CFMs) apply the foundation-model paradigm to causal inference, replacing bespoke per-problem estimator pipelines with networks pretrained once at scale. CFMs estimate causal quantities such as the average treatment effect on entirely new datasets through in-context learning, without model updates. The work serves as a practical introduction to the emerging area, covering background in causal inference and machine learning and including example code and Jupyter notebooks.

ThreatsDay: Gogs 10.0 RCE, n8n Workflow-to-RCE, $10M Reward, GLM

Hacker News ThreatsDay roundup: Defender BTR.sys driver abuse, DoJ charges 17 Mabna Institute members over IRGC-linked intrusions, Grandoreiro sideloading, OpenAI monitoring.

Check Point researchers showed Microsoft's signed Defender Boot-Time Removal driver (BTR.sys) can be repurposed as a universal kernel operation engine to bypass endpoint security without BYOVD. The DoJ charged 17 members of Iran's Mabna Institute, which on behalf of the IRGC stole over 31 TB of academic data from 144 US universities and compromised roughly 8,000 of 100,000 targeted professor accounts; the State Department offered a $10 million reward for five defendants. Separately, Acronis tracked a Grandoreiro campaign abusing DLL sideloading in the Duplicate Files Finder app across Latin America and Spain, while ErrTraffic ClickFix campaigns deliver Cruciferra (BYOVD) and Remus Stealer. OpenAI also previewed Private Safety Processing, a privacy-centric approach to monitoring model misuse without retaining customer content.

Fake Gemini installer delivers Vidar infostealer via Google Colab lure

Attackers used a fake Google Gemini installer hosted on Google Colab to deliver a Go-compiled Vidar infostealer that stole browser credentials from an EMEA company.

Darktrace investigated an EMEA company infection where the top search result for a Gemini-related filename pointed to a Google Colab page that redirected to a fake 'Windows Software Hub' hosting a malicious executable. The ZIP contained a README instructing victims to run the file as administrator and add it to antivirus exceptions, delivering a newer Go-compiled Vidar variant that used dtm[.]kijangturbo88[.]top over Telegram-based infrastructure. The malware stole browser credentials and other sensitive data; Darktrace's Autonomous Response blocked the C2 and quarantined the device.
