Hackers Use AI-Assisted CEO Emails to Trick Finance Teams Into Sending $50,000 Payments.
Microsoft tracked a million-message AI-assisted BEC campaign impersonating executives with fake ServiceNow invoices to steal ~$50,000 ACH payments.
Microsoft detected over one million messages in a BEC campaign running August 3-5, using AI-assisted phishing templates, executive impersonation, and fabricated ServiceNow subscription invoices to trick finance teams into authorizing fraudulent ACH payments of roughly $50,000. The US received 87.7% of volume. Attackers used lookalike domains like service-nowinc[.]com registered just days before delivery, with no compromise of ServiceNow itself. Telltale signs included verbose HTML comments, uniform formatting, and inconsistent forwarded-message headers.

⚡ 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.

Microsoft sees some new wrinkles in invoice-scam emails
Microsoft researchers observed a BEC invoice scam sending 1M+ AI-assisted emails impersonating executives and ServiceNow to request ~$50,000 payments.
Microsoft researchers tracked a campaign of more than one million invoice-scam emails launched in early August, with about 88% of targets in the United States. Attackers impersonated top executives and ServiceNow, fabricating forwarded email threads and invoices to convince accounts payable teams to send payments of nearly $50,000. Microsoft found indicators such as extensive HTML comments and highly uniform template construction consistent with AI-assisted campaign development, though it could not independently establish how much content AI generated.

A stranger has been reading Salesforce and ServiceNow portals worldwide for 17 months
Reco tracks City-Forum, an actor abusing Salesforce and ServiceNow guest-user access from one IP for 17 months to enumerate portal data.
Reco's City-Forum investigation found one IP address, tied to a dormant 2002 domain, anonymously enumerating Salesforce Experience Cloud and ServiceNow portals across telecoms, banks, enterprise software vendors, and public sector since at least March 2025. No vulnerability was exploited and no credentials were used; the actor abused over-permissioned guest users, including a previously undocumented ServiceNow portal search endpoint, with the busiest single target logging over 560,000 events. Audit logs show what was requested but not which records or fields were returned, so defenders must replay anonymous requests to assess exposure.
