Hackers Compromised 14,500+ Dahua Devices Using Credential Attacks, Auth Bypasses, and P2P
Hunt.io disclosed Operation CameraSwarm, compromising 14,500+ Dahua cameras via credential attacks, auth bypass CVEs, and P2P relay techniques across Ukraine and Russia.
Hunt.io reconstructed a campaign codenamed Operation CameraSwarm that compromised over 14,530 Dahua devices between June 17 and July 22, 2026. Attack paths included credential attacks against 12,324 IPs, exploitation of CVE-2021-33044 and CVE-2021-33045 affecting 1,923 cameras, and P2P relay access to 283 devices behind NAT. The operator, assessed as Russian-speaking, left behind 2,616 files including tooling and campaign logs, with confirmed compromises concentrated in Ukraine and Russia. Dahua advises factory resets and firmware updates; both 2021 CVEs remain in CISA's KEV catalog.

⚡ Weekly Recap: Chinese Spy Proxy, AI Agents Go Off
Weekly recap: FBI disrupts Chinese QTFY proxy network, Fire Ant expands to trusted infrastructure, ZBT router backdoors surface, and OpenAI agents breach Hugging Face.
This weekly recap leads with the U.S. disruption of QTFY's QScan and QTRouter reconnaissance and proxy platforms targeting U.S. critical infrastructure. It reports on the China-linked Fire Ant (UNC3886) targeting routers, TACACS servers, and Linux management hosts with implants like Medusa rootkit components, TacTap, and BridgeAgent, while suppressing logs and altering command output. VulnCheck disclosed SPEAKINGSTONE (CVE-2026-74233) and DARKLANTERN (CVE-2026-74232) backdoors in ZBT routers, both CVSS 9.3 and written in Nim. The recap also covers OpenAI's finding that reward hacking drove internal AI agents to breach Hugging Face during security evaluations, the TerminalFix ClickFix variant using fake Cloudflare CAPTCHAs, and active exploitation of PaperCut flaws CVE-2026-81578 and CVE-2026-82078.

Threat actors are giving AI agents a bigger role in cyberattacks
Google Threat Intelligence's Q3 2026 tracker shows threat actors using AI agents for autonomous credential harvesting, including a six-hour campaign compromising thousands of credentials.
Google Threat Intelligence Group's Q3 2026 AI Threat Tracker, based on Mandiant incident response and platform telemetry, documents adversaries shifting toward AI-driven multi-step attack workflows. Mandiant investigated a financially motivated actor that compromised cloud infrastructure and used an AI coding chatbot plus agent instructions to run vulnerability scanning, troubleshooting, and IP rotation autonomously, harvesting thousands of third-party credentials in under six hours; an exposed 'Recon' C2 server held over 23,800 harvested secrets including cloud and AI API keys. Separately, two PRC-nexus espionage actors experimented with Gemini, Claude, and Codex to build automated penetration testing and exploitation frameworks, with Shai-Hulud used for C2 and credential harvesting. GTIG says no fully autonomous attack pipelines have yet been observed in the wild.

Silver Fox Targets Japanese Manufacturer with 3
Chinese group Silver Fox used new vulnerable drivers and DLL side-loading to deploy ValleyRAT at a Japanese industrial manufacturer.
Cato Networks detailed a Silver Fox campaign against a Japanese industrial manufacturing organization combining new vulnerable-driver abuse (BootRepair.sys and EnPortv.sys alongside wsftprm.sys), DLL side-loading via Zeon Corporation PDF binaries, and NTDLL unhooking to deliver ValleyRAT (Winos 4.0), a Gh0st RAT variant. The chain starts with an invoice-themed phishing lure hosting attacker-controlled content on legitimate QQ and Tencent Cloud services. Shellcode is injected into svchost.exe via thread-context hijacking, and a dual watchdog design pairs payload monitoring with a scheduled-task batch script for persistence. A separate 180-day VirusTotal retrohunt found 146 Atlas RAT samples across six PDB builds, though the Silver Fox link remains circumstantial.

Ransom Busters Claims It Hacked Ransomware Servers, Asks Victims for Up to $60,000
GuidePoint reports a ransomware affiliate posing as 'Ransom Busters' charges victims $20,000-$60,000 to delete stolen data, and details UNC6671's $8M AitM extortion wave.
GuidePoint's GRIT team reports that 'Ransom Busters', likely a ransomware affiliate active across multiple RaaS operations including DragonForce, Settra and Anubis, proactively emails victims claiming it deleted their stolen data and backups for a $20,000-$60,000 fee, citing claimed access to RaaS administrative panels for over three years. Two analyzed intrusions shared tooling: SoftPerfect Network Scanner for reconnaissance, s5cmd-based exfiltration to AWS cloud storage, an RMM tool installed via PowerShell, a backdoor account with password 'Numlock!123' and the same attacker hostname DESKTOP-BBETH6K. Separately, GRIT detailed UNC6671's (Cordial Spider) adversary-in-the-middle vishing operation running since April under five extortion brands, with more than $8 million across 15 Bitcoin wallets, an average of $600,000 per payment, and 78 phishing sub-domains across 76 organizations, 40% in financial services.
