ConsentFix: a New ClickFix Variation for Compromising Microsoft 365 Accounts

, , ,

Researchers have identified ConsentFix, a new variation of the ClickFix social engineering attack that enables cybercriminals to hijack Microsoft 365 accounts via OAuth tokens without stealing passwords. By tricking users into dragging a session token URL into an attacker-controlled page during a fake authentication process, attackers gain access to corporate email, documents, Teams, and other cloud services, facilitating data exfiltration and lateral movement within organizations. The widespread availability of ConsentFix attack blueprints increases the risk of such intrusions, highlighting the need for robust email security solutions and employee awareness training.

Hugging Face – Security Incident Disclosure

, ,

Hugging Face disclosed that in July 2026 their production infrastructure was compromised by an autonomous AI-driven attacker exploiting code-execution vulnerabilities in their dataset processing pipeline, leading to unauthorized access to internal datasets and credentials. They contained the intrusion by closing the vulnerabilities, rotating credentials, rebuilding affected nodes, enhancing cluster controls, and used their own open-weight AI models for rapid forensic analysis, highlighting the emerging challenge of AI-powered attacks and the need for AI-assisted defense capabilities. The investigation continues with external cybersecurity experts, and affected users are advised to rotate tokens and monitor accounts.

Nearly a Million Passports Just Exposed on the Public Internet—and Anyone Could Access Them with a Simple URL

, ,

Nearly a million passports and photo IDs from multiple European countries were exposed on public web servers without any authentication, encryption, or access controls, allowing anyone with a URL to access these sensitive documents for months. The data, collected for age verification by the company Nefos and associated cannabis clubs, remained vulnerable due to critical security misconfigurations, raising significant risks of identity theft and document fraud for affected individuals. This incident highlights severe failures in data stewardship and compliance with established security standards for handling identity verification information.

China-Linked Hackers Backdoored Linux Login Software to Hide for Nearly a Decade

, ,

A China-linked threat group known as Velvet Ant backdoored critical Linux login software components PAM and OpenSSH to maintain covert access inside isolated networks for nearly a decade, starting from 2016. By altering trusted login programs themselves, the attackers bypassed traditional defenses, capturing credentials and commands without exploiting new malware, making the intrusion difficult to detect and remediate. Security experts recommend monitoring these login files for changes and verifying software integrity to detect and remove such stealthy backdoors effectively.
