Massive AWS Credential Leak Exposes 817 Corporate Accounts to Full Takeover
Between August 2022 and August 2026, Truffle Security discovered over 9,300 Amazon Web Services (AWS) access keys publicly exposed across code repositories, Git history, datasets, Docker images, and CI logs. Of these, 817 keys were linked to corporate accounts, with 526 being AWS root keys granting unrestricted administrative access. Researchers found that 242 keys belonged to IAM users with AdministratorAccess policies, effectively providing full control over corporate AWS environments. Hugging Face emerged as the largest single source with 8,482 exposed keys, many remaining active for years without rotation. This incident highlights the persistent challenge of credential management in cloud environments as organizations increasingly rely on Infrastructure as Code and automated deployment pipelines. With the median age of exposed keys being over five years and only 13.7% showing evidence of rotation, the findings underscore critical gaps in security hygiene that threat actors actively exploit for cryptomining operations, data exfiltration, and persistent access establishment.

Microsoft Defender's Own Driver Weaponized for Endpoint Security Bypass
In August 2026, Check Point Research disclosed a technique that weaponizes Microsoft Defender's own legitimately signed boot-time remediation driver (BTR.sys) to perform arbitrary kernel-level file and registry operations on Windows systems. The technique, dubbed 'BTR Reforged,' affects all Windows versions from Windows 7 through Windows 11 25H2 and exploits a built-in driver that cannot be blocked without disrupting Defender itself. Researchers demonstrated live deletion of the entire Defender stack on a fully updated Windows 11 system with Tamper Protection active, requiring only administrator privileges with SeLoadDriverPrivilege. Unlike traditional bring-your-own-vulnerable-driver attacks, this technique uses infrastructure present in every Windows installation, making it particularly concerning for endpoint security bypass scenarios. This discovery highlights the evolving sophistication of endpoint security bypass techniques, where attackers increasingly leverage legitimate system components rather than external vulnerable drivers that can be easily blocklisted by security vendors.
