Cisco Secure Firewall Management Center Software sftunnel Root Arbitrary Code Execution Vulnerability
Cisco patched an sftunnel flaw in Secure Firewall Management Center letting an authenticated remote attacker execute arbitrary commands as root.
A vulnerability in the sftunnel inter-device communication protocol of Cisco Secure Firewall Management Center allows an authenticated remote attacker to execute commands as root. The flaw stems from incorrect permissions allowing a registered sftunnel peer to write an arbitrary file anywhere on the device, exploitable via connection hijacking or crafted sftunnel commands. Cisco has released software updates.

TWINLOOT Abuses SharePoint and Teams to Steal Credentials and Move Across Networks
Ontinue disclosed TWINLOOT, a Python implant hiding C2 in SharePoint dead drops and Teams TURN relays, harvesting credentials and pivoting via reverse SOCKS5.
Ontinue's Cyber Defense Center identified TWINLOOT during a July 2026 campaign investigation: a modular, PyArmor-hardened Python implant (a 39 MB bootstrap-fat.pyc loader) whose entire C2 infrastructure lives inside trusted Microsoft services. Tasking flows through SharePoint Online file dead drops polled every 15 seconds via the Microsoft Graph API, while interactive operator access uses WebRTC DataChannels relayed by Microsoft Teams TURN servers; Graph traffic is driven by the victim's own headless Edge browser. The implant harvests Windows credentials with fake lock screens, offers a reverse SOCKS5 pivot for lateral movement to SMB, RDP, WinRM, and MSSQL, executes commands, and persists on hosts. Initial access is assessed to be Teams social engineering masquerading as IT support, prompting a PowerShell command to download the payload.

2,000 Leaked Documents Reveal How Russia Turns Engineering Students Into GRU Cyber Operators
Leaked Bauman Moscow State Technical University files reveal a hidden GRU training pipeline feeding APT28 and Sandworm units.
More than 2,000 leaked Bauman Moscow State Technical University documents show that Department No. 4, a hidden program inside the Military Training Center, trained roughly 250 career and reserve students for GRU cyber and intelligence roles across six academic years. Graduates were linked to Military Unit 26165 (APT28), Unit 74455 (Sandworm/APT44) and Unit 29155, and former Unit 26165 commander Viktor Netyksho was involved in department oversight. Reporting by The Insider, The Guardian, Le Monde, Der Spiegel and other outlets, with independent analysis by DomainTools, estimates 10-15 students annually were selected for GRU-related assignments before graduating.
