US offers $10 million for info on Iranian allegedly behind cyberattacks on critical infrastructure
State Department offers $10M reward for IRGC Cyber-Electronic Command chief Amir Yaryab over critical infrastructure cyberattacks across US, Europe, and Middle East.
The U.S. State Department posted a $10 million reward for information on senior Iranian official Amir Yaryab, who allegedly leads the IRGC's Cyber-Electronic Command (CEC) and directs hacking groups including CyberAv3ngers, Dadeh Afzar Arman (DAA), and Mehrsam Andisheh Saz Nik (MASN).

New PATCHCORD Backdoor Targets Afghan Telecom and Indian Critical Infrastructure
Acronis links APT36 (Transparent Tribe) to new backdoors PATCHCORD and SHEETCORD targeting Afghan Telecom and Indian government, defense, and energy networks.
Acronis TRU described an ongoing Pakistan-aligned campaign attributed with moderate confidence to APT36, delivering a previously undocumented C/C++ backdoor named PATCHCORD via fake VPN installers impersonating Afghan Telecom (AFTEL) and telecom management tools. PATCHCORD persists by hijacking browser shortcuts for Chrome, Edge, and Firefox, registers with a single C2 server, and executes shellcode and arbitrary cmd.exe commands. Infrastructure analysis revealed SHEETCORD, a Go backdoor combining SHEETCREEP and PATCHCORD features that uses Google Sheets for C2 and a PowerShell-based remote execution, delivered via a fake site mimicking India's National Informatics Center. APT36 has used PATCHCORD since at least March 2026, including a variant with anti-analysis features used against India's energy sector, and the toolkit includes antnium, GateSentinel, SuperShell, and exploits for CVE-2024-6387.

TP-Link Tapo Camera Flaw Lets Attackers Gain Admin Access Without Password
Two flaws in TP-Link Tapo C200 cameras allow network-adjacent admin access without a password (CVE-2026-15315) or DoS (CVE-2026-15316); fixed in V5_1.4.6.
OPSWAT Unit 515 researchers discovered CVE-2026-15315, an authentication bypass in the Tapo C200's local HTTPS management interface on port 443, where an alternative verification path accepts a replayed device-generated value, letting unauthenticated network-adjacent attackers establish admin sessions. CVE-2026-15316 causes a denial-of-service crash in the camera's HTTPS service via oversized encrypted Wi-Fi credential data during onboarding. TP-Link confirmed both issues after the April 16, 2026 report and released firmware V5_1.4.6 on August 18, 2026. OPSWAT says additional potentially critical findings remain under coordinated disclosure.

FrostyGoop’s Zoom-In: A Closer Look into the Malware Artifacts, Behaviors and Network Communications
Unit 42 dissects FrostyGoop OT malware, which sent Modbus TCP commands to disrupt heating for 600+ apartment buildings in Ukraine.
Palo Alto Unit 42 analyzed new FrostyGoop/BUSTLEBERM samples, the ninth known ICS-centric malware, first used against a Ukrainian municipal energy company by sending Modbus TCP commands to ENCO control devices. The attack caused a two-day heating outage affecting over 600 apartment buildings during sub-zero temperatures. The Go-compiled malware accepts Modbus register operations and timing parameters via command-line arguments or a JSON configuration file, uses an obscure open-source Modbus library, and checks the Windows BeingDebugged flag to evade debuggers. Unit 42 telemetry recorded over 1 million Modbus TCP devices exposed to the internet between September and October 2024.

Remote Desktop Services Failures on Windows Servers Following September Update
September 2026 Patch Tuesday updates cause Windows Server 2019/2022/2025 RDS sessions to freeze, forcing administrators to roll back.
Cumulative updates KB5122876 (Windows Server 2019), KB5122882 (2022), and KB5122871 (2025) trigger Remote Desktop Services freezes hours after boot, with RDP connections hanging at 'Connecting…' and Event ID 20498 logged. Administrators trace the fault to an apparent deadlock in RDPSERVERBASE!WDLIB_Close during session teardown; only hard resets restore service and the issue recurs. The same September release patched roughly 973 vulnerabilities, including two actively exploited zero-days (CVE-2026-81963, CVE-2026-85880, both in CISA's KEV) and a critical RDS RCE, CVE-2026-69525 (CVSS 9.8). Workarounds include DISM-based removal of the update or an unofficial FeatureManagement registry key disabling the suspected audio-redirection code path; Microsoft has not yet confirmed the bug.

I Think the Military Commissary Freezers Were Hacked
Refrigeration failures at six-plus US military commissaries prompt speculation of a cyber attack on DeCA's remote monitoring systems; Pentagon acknowledges possible disruption.
The author documents near-simultaneous freezer and refrigeration failures at confirmed installations including Fort Huachuca, F.E. Warren AFB, Fort Irwin and Travis AFB on August 26-27, with freezers entering defrost mode that heated and spoiled food. DeCA's Remote Monitoring Control System controls defrost across roughly 182 locations, and an unverified comment attributed the Fort Huachuca failure to a network issue. Stars and Stripes and Military Times independently reported the multi-base failures, and the Pentagon acknowledged a 'possible refrigeration disruption,' though no evidence of hacking has been confirmed.
