NightEagle targets Russian companies

Kaspersky links NightEagle (APT-Q-95) attacks on Russian firms to compromised VPN credentials, a GhostContainer Exchange backdoor, RDP tunneling, BlueKeep exploitation, and DCSync.

Kaspersky's Global Emergency Response Team investigated NightEagle (APT-Q-95) incidents over the past year, finding the group—active since at least 2023 and formerly focused on Asia—now targeting Russian businesses. Attackers used compromised VPN credentials and deployed the GhostContainer .NET backdoor on Microsoft Exchange servers, built from Neo-reGeorg, a CVE-2020-0688 exploit, and ysoserial's GhostWebShell, injected in memory via VIEWSTATE manipulation with AMSI bypass. For lateral movement they combined Microsoft dev tunnels with rdp2tcp over RDP, exploited BlueKeep (CVE-2019-0708) to create local admin accounts, and performed DCSync replication against Active Directory.

Hackers Use Autonomous AI Agents to Harvest Thousands of Credentials in Under 6 Hours

Google Cloud documents a financially motivated actor using autonomous AI agents on a compromised cloud tenant to harvest 23,800+ credentials in under six hours.

Google Cloud reports that an attacker compromised a victim's cloud environment and deployed a multi-agent framework driven by preconfigured Markdown playbooks to autonomously handle vulnerability scanning, credential collection, error troubleshooting, and IP rotation. An exposed command-and-control server hosted the 'Recon' framework with a live dashboard managing over 23,800 harvested secrets, including cloud and AI-service API keys. The report also ties DUSTMAKER to UNC6780/TeamPCP, targeting AI development tools and CI/CD systems via trojanized MCP packages such as tiktoken_mcp. Google has disabled linked assets and updated protections after the actors' operational security failures.

One runaway AI agent racked up a $50,000 cloud bill

Mandiant's AI Risk and Resilience report details prompt injection, AI supply chain compromises, agent abuse, and a runaway agent that accrued $50,000 in cloud charges.

Mandiant, drawing on Google Threat Intelligence Group (GTIG) observations, warns that poisoned data sources, model dependencies, and extension hooks can turn AI agents into channels for reconnaissance, lateral movement, and sandbox escape. Mandiant responded to incidents involving UNC6780 (TeamPCP), who stole AI service credentials and used prompt injection against AI coding assistants, while GTIG disclosed the first confirmed criminal use of an AI-developed zero-day exploit in a planned mass exploitation campaign. Red team tests showed an AI assistant manipulated into cloning internal repositories to an external GitHub account, and a runaway accounting agent made over 15,000 costly API calls in under an hour, generating roughly $50,000 in cloud charges.

Active Exploitation Attempts Target WSO2 API Manager JWT Bypass With Forged Admin Tokens

watchTowr observed active exploitation of CVE-2026-5430, a WSO2 API Manager JWT bypass using forged admin tokens, risking credential theft and account takeover.

CVE-2026-5430 (CVSS 9.8-10.0), an improper cryptographic signature verification flaw in WSO2 API Manager, lets JWT authentication be bypassed with unsupported algorithms, enabling administrative account takeover. watchTowr honeypots captured forged JWT tokens with baked-in administrator privileges on September 13, 2026, which could expose API credentials, consumer keys, and secrets for every registered application. Affected products include WSO2 API Manager 4.1.0-4.6.0, API Control Plane, Traffic Manager, and Universal Gateway. Fixes are available via GitHub pull requests and subscription update levels, and users are urged to patch immediately.

One Exploit Chain, Two Espionage Campaigns: Chrome and Windows Under Fire

Two China-linked APT groups reused identical Chrome/Windows zero-day chain against NGOs, deploying GRIMWIDGE backdoor and LONGTALE credential-stealing extension.

Volexity reports that China-linked actors UTA0560 and JungleBamboo (APT31/TA412) ran byte-identical Chrome/Windows exploit chains against NGOs starting September 1, 2026, combining Chrome type confusion CVE-2026-85046, WebAssembly sandbox escape CVE-2026-87491, and Windows kernel flaw CVE-2026-85880. The Chrome bug was fixed in Chromium source but not yet shipped to Chrome users, making it an effective zero-day with an unusual patch gap. UTA0560 delivered the in-memory GRIMWEDGE JScript backdoor, while JungleBamboo deployed the SUPERSTOMP loader installing LONGTALE, a malicious Chrome extension disguised as Google Gemini that steals cookies, session tokens, and keystrokes. Volexity assesses with low confidence the exploit chain was sold or shared among different Chinese end-users.

Attackers hijack HBO Max’s Reddit account for 48-hour malvertising blitz

Attackers hijacked HBO Max's verified Reddit account to push 108 ClickFix infostealer ads delivering AMOS, MacSync, and crypto clippers.

Threat actors compromised the verified u/hbomax Reddit account and ran 108 ClickFix malvertising ads in 48 hours as part of the PasteSwitch operation, analyzed by Hudson Rock and ADAMnetworks. macOS victims received curl-to-zsh payloads (MacSync, AMOS Helper, fake Ledger/Trezor/Exodus wallets harvesting BIP39 seed phrases); Windows users got Amatera via mshta and PowerShell loaders. Clipper C2 addresses are stored in Binance Smart Chain smart contracts, with 36 mainnet changes observed between March and July 2026.
