Windows 11 machines remain open to downgrade attacks, where attackers can abuse the Windows Update process to revive a patched driver signature enforcement (DSE) bypass.

Posing as an application used to locate Ukrainian military recruiters, a Kremlin-backed hacking initiative delivers malware, along with disinformation designed to undermine sign-ups for soldiers in the war against Russia.

A suspected Russian hybrid espionage and influence operation has been observed delivering a mix of Windows and Android malware to target the Ukrainian military under the Telegram persona Civil Defense. Google's Threat Analysis Group (TAG) and Mandiant are tracking the activity under the name UNC5812. The threat group, which operates a Telegram channel named civildefense_com_ua, was created on

Relying on EOL software leaves critical systems exposed — making it a problem no business can afford to ignore.

A new attack technique could be used to bypass Microsoft's Driver Signature Enforcement (DSE) on fully patched Windows systems, leading to operating system (OS) downgrade attacks. "This bypass allows loading unsigned kernel drivers, enabling attackers to deploy custom rootkits that can neutralize security controls, hide processes and network activity, maintain stealth, and much more," SafeBreach

The Computer Emergency Response Team of Ukraine (CERT-UA) has detailed a new malicious email campaign targeting government agencies, enterprises, and military entities. "The messages exploit the appeal of integrating popular services like Amazon or Microsoft and implementing a zero-trust architecture," CERT-UA said. "These emails contain attachments in the form of Remote Desktop Protocol ('.rdp'

Kremlin intelligence carried out a wide-scale phishing campaign in contrast to its usual, more targeted operations.

On Python < 3.11 on Windows, `os.path.isabs()` does not catch UNC paths like `//server/share`. Werkzeug's `safe_join()` relies on this check, and so can produce a path that is not safe, potentially allowing unintended access to data. Applications using Python >= 3.11, or not using Windows, are not vulnerable.

### Impact A vulnerability has been identified whereby RKE2 deployments in Windows nodes have weak Access Control Lists (ACL), allowing `BUILTIN\Users` or `NT AUTHORITY\Authenticated Users` to view or edit sensitive files which could lead to privilege escalation. The affected files include binaries, scripts, configuration and log files: ``` C:\etc\rancher\node\password C:\var\lib\rancher\rke2\agent\logs\kubelet.log C:\var\lib\rancher\rke2\data\v1.**.**-rke2r*-windows-amd64-*\bin\* C:\var\lib\rancher\rke2\bin\* ``` **This vulnerability is exclusive to RKE2 in Windows environments. Linux environments are not affected by it.** Please consult the associated [MITRE ATT&CK - Technique - Exploitation for Privilege Escalation](https://attack.mitre.org/techniques/T1068/) for further information about this category of attack. ### Patches Patched versions include RKE2 `1.31.0`, `1.30.2`, `1.29.6`, `1.28.11` and `1.27.15`. ### Workarounds Users are advised to do a fresh install of their ...
