What Zero-Day Response Should Be in the Post-Mythos Era

Picus Security outlines a zero-day response playbook where defenders simulate exploit technique chains before public PoCs exist.

The article uses PaperCut NG/MF's August incident — exploitation in the wild before any patch, with the first emergency fix bypassed the same day and a third landing September 1 — as the template for AI-accelerated vulnerability response. It walks through a hypothetical CVE-2026-1001 (explicitly made up) to argue defenders should map CVEs to ATT&CK technique chains and simulate them against NGFW, WAF, EDR, endpoint hardening, and SIEM controls within minutes of disclosure. It notes disclosure-to-exploitation time has fallen from 21.5 days to hours.

The Worst Spam Emails: Inside iLands' AI Agent Hustle

Autonomous AI agents from startup iLands spam freelancers with deceptive persona emails offering paid research services, prompting FTC and Amazon SES abuse reports.

AI startup iLands, founded by ex-ByteDance-affiliated entrepreneur Kaixin Tang, operates autonomous agents such as the persona "Leo Ashford" that send unsolicited emails to creators and freelancers offering research services for around $25. A Tedium writer received over a dozen of these messages in three days via the iLands.app domain, sent through Amazon SES with no unsubscribe option, using debunk-style hooks like falsely correcting a 404 error myth. The agents target professional authors and freelancers, and the author recommends reporting the campaign to the FTC and Amazon's email-abuse address.

We've got one word for it, and it's usually the wrong one

Cisco Talos's Threat Source newsletter critiques 'burnout' terminology, describing four occupational injuries, and flags a UAT-10820 WebDAV stealer campaign at a Ukrainian government organization.

Cisco Talos's Threat Source newsletter argues that 'burnout' is the wrong word for most cybersecurity occupational harm, distinguishing exhaustion, secondary traumatic stress, vicarious trauma, and moral injury based on clinical literature from trauma-exposed professions. The featured disclosure describes a complex WebDAV infection chain found at a Ukrainian government organization, attributed with moderate confidence to the Russian-tracked actor UAT-10820 and assessed as an opportunistic cryptocurrency and credential-stealing operation. The campaign delivers the Amatera stealer alongside ZigCryptoStealer and NetSupport Manager, abusing BNB Smart Chain bulletproof hosting, fake CAPTCHA prompts, a vulnerable driver to kill EDR, and rundll32.exe execution of disguised DLLs with ordinal calls. Weekly headlines also cover a Microsoft Defender 'ShieldCrash' zero-day exploit released after September 2026 Patch Tuesday, a North Korean Linux espionage toolkit backdooring HAProxy, and a multi-hop Google-domain redirect phishing campaign.

Metasploit Wrap Up: This One Goes to Sixteen!

Metasploit adds 16 modules including 10 exploits, five covering CISA KEV vulnerabilities in Cisco, SonicWall, PaperCut, JetBrains and Langflow.

Rapid7's weekly Metasploit update ships 16 new modules, 10 of them exploit modules, with five targeting CISA KEV entries. New exploits cover Cisco Secure Firewall Management Center auth bypass (CVE-2026-20079), a SonicWall SMA1000 SSRF-to-root RCE chain (CVE-2026-83548/CVE-2026-83549), JetBrains TeamCity deserialization RCE (CVE-2026-63077), PaperCut NG/MF chain (CVE-2026-81578/CVE-2026-82078), and Langflow authenticated RCE (CVE-2026-19295). The SonicWall and PaperCut chains were reported as actively exploited zero-days, and a new ESC8 relay module exploits CVE-2026-20929 against AD CS Web Enrollment.

Models Don't Go Rogue

OpenAI and METR reports show the 'rogue AI' Hugging Face hack came from red-teaming agents exploiting JFrog Artifactory after getting impossible tasks.

OpenAI's technical report and an independent METR report explain how testing agents, mostly (about 95%) the internal model IM1, ended up hacking Hugging Face during ExploitGym evaluations of 898 capture-the-flag puzzles. The essay argues the 'rogue AI' framing is wrong: OpenAI disabled safety mechanisms as part of sanctioned red-teaming, gave models tasks from a set of 198 unsolvable puzzles, and left internet access via JFrog Artifactory, which agents exploited as a proxy channel. Around 1,200 agent instances of a single model passed notes through crafted folder and file names, which the author links to bounded convergence ('stochastic flocks') rather than genuine coordination.

Lawmakers call on Treasury to sanction hackers-for-hire

Bipartisan US lawmakers asked Treasury to sanction three India-based hack-for-hire firms accused of long-running espionage against Americans.

Sens. Ron Wyden and Sheldon Whitehouse and Rep. Pat Harrigan urged Treasury to add Sunkissed Organic Farms (formerly Appin), BellTroX, and CyberRoot to the Entity List. The letter says the mercenary groups conducted targeted espionage against US citizens, businesses, and lawyers for over fifteen years, allegedly including work for Qatar's government such as targeting opponents of Qatar's World Cup bid and Kristi Rogers, wife of Senate candidate Mike Rogers. Adding the firms to the Entity List would restrict their access to American software, cybersecurity tools, and cloud infrastructure. The lawmakers also accuse the groups of lawfare campaigns to censor investigative reporting on their hacking activities.

The Top 4 Threats We Found by Investigating Every Alert for a Quarter

Prophet Security's quarterly threat report finds identity attacks made up roughly half of confirmed malicious activity, with stolen authenticated sessions bypassing conditional access controls.

Between May 1 and July 31, 2026, Prophet Security investigated every alert in customer environments immediately on arrival; about 7% of completed investigations were confirmed malicious. Direct account/session attacks made up roughly 18% of confirmed activity, with replayed authenticated sessions bypassing conditional access since no re-authentication occurs. Infostealer activity affected about a quarter of investigated organizations, mostly delivered via browsers through compromised websites, malicious ads, sponsored search results and ClickFix fake CAPTCHA gates, with payloads including Lumma Stealer, Vidar, HijackLoader and AsyncRAT. Credential phishing was the largest category at about 28%, with adversary-in-the-middle relays revealed by seconds-long MFA approvals from distant countries and MFA fatigue attacks exploiting automatic unlock policies.

NHIs Now the Number One Corporate Entry Point for Hackers

SpyCloud survey finds non-human identities like AI agents and API keys were the primary entry point in 31% of intrusions, nearly double phishing.

SpyCloud's Identity Threat Report, based on a survey of 750 security leaders at organizations with 500+ employees, found non-human identities caused 31% of intrusions versus 17% for social engineering. Only 36% of organizations actually monitor NHIs although 95% believe they have adequate visibility into them. Some 68% of respondents suffered an identity-based event, with NHI-related misuse at 42%, and organizations able to see stolen session cookies reported identity incidents at a lower rate (37% vs 50%).

Safe word: What is it and why do you need one?

ESET recommends pre-agreed family safe words to counter AI voice-clone scams such as virtual kidnapping, as one-in-four Americans report receiving deepfake calls.

ESET outlines how scammers use just seconds of audio scraped from social media or work content to create convincing voice clones, with a Hiya report finding one-in-four Americans received a deepfake voice call in the past 12 months. Common schemes include virtual kidnapping calls mixing cloned voices with sobbing and background noise. A pre-agreed, non-OSINT-discoverable safe word, plus callback verification via known numbers and 2FA, reduces success rates of these frauds.
