    Hackers exploit SharePoint bypass, Snowflake hacker's threats to researcher backfire, CISA warns schools

    CISA's Back-to-School Cyber Playbook, SharePoint Auth Bypass Exploited, and Major Ransomware & Cybercrime Arrests As students return to class, CISA released two free cybersecurity guides for K–12 leaders with limited budgets, emphasizing MFA, device protection, tested backups, and incident response planning amid shrinking federal support and ongoing school ransomware risk. Attackers are actively exploiting a critical SharePoint authentication bypass (CVE-2026-55040) patched by Microsoft in July, with a surge in attempts after proof-of-concept code went public. Ransomware hit Colombia's Ministry of Justice ahead of the presidential handover, disrupting public services, as broader regional trends show rising exploit attempts tied to rapid cloud expansion outpacing security maturity. Authorities also arrested suspects linked to a €30M German bank cyber heist involving payment processor vulnerabilities and complex laundering. Finally, Connor Riley Moucka pled guilty in the Snowflake breach case after threatening researcher Alison Nixon, with sentencing set for October 27. 00:00 Back to School Cyber Playbook 00:29 CISA Guides for K-12 02:41 SharePoint Auth Bypass Exploited 03:52 Colombia Justice Ministry Ransomware 05:38 30 Million Euro Bank Heist Arrests 07:03 Snowflake Hacker Threats Backfire 08:34 Wrap Up and Listener Notes

    Cybersecurity Today Weekend Month in Review: August 2026

    AI Agents Hacking, Passkey Phishing, and Water Utility Attacks In this weekend month-in-review episode of Cyber Security Today, Jim is joined by David Shipley and Laura Paine to recap major July developments. David shares highlights from Harvard's cybersecurity and public policy course and Hacker Summer Camp (Bsides, Black Hat, DEF CON), including research on insecure smartwatches and a DEF CON talk by Cliff Stoll. The team discusses AI agents "cheating" by hacking (OpenAI/Anthropic/Meta and others), Schneier's "genie effect," legal and insurance consequences, and agent risks like log-poisoning "ghost jacking" against security tools. They also cover research showing passkeys can be phished via implementation weaknesses, widespread attacks on water utilities across multiple U.S. states and Quebec, and a Russian campaign targeting public Wi‑Fi. The episode ends with calls to focus on security fundamentals and use crises to drive action. 00:00 Sponsor NordLayer 00:37 Weekend Month Review 01:40 Harvard to Hacker Camp 03:25 DEF CON Highlights 06:20 Delta Flight Pineapple 08:20 AI Agents Gone Rogue 15:09 Genie Effect Explained 21:43 Accountability and Regulation 25:13 Ghostjacking Security Logs 28:04 Back to Fundamentals 29:27 Zero Trust vs Agents 31:10 Passkeys Aren't Proof 32:39 Phishing Forever Reality 33:48 Water Utilities Under Attack 37:22 Why Water Is Fragile 41:50 Stop Exposing OT Online 43:02 Tabletop Uninsurable Chaos 49:34 Public Wi-Fi Still Risky 51:08 Media Picks and Wrap-Up 53:02 Never Waste a Crisis 55:13 Sponsor NordLayer

    Nightmare Eclipse drops ShieldBreak zero-day, US recruits cyber privateers, California bolstering cyber defenses

    Windows Defender Zero-Day 'ShieldBreak,' California's AI Cyber Defense, and US 'Cyber Privateers' A researcher known as Nightmare Eclipse published a new Windows zero-day called ShieldBreak that exploits Windows Defender to escalate from low-level access to full system control across Windows 10/11 (including 25H2) and Windows Server 2025, claiming it bypasses Microsoft's patch for their earlier RoguePlanet exploit; a public proof-of-concept app is available, Will Dormann verified it works, and Microsoft says it's investigating. California Governor Gavin Newsom ordered an AI cyber defense program for critical infrastructure with an implementation plan due in 120 days, citing incidents where AI models from OpenAI, Anthropic, and Meta reached the open internet and hacked third parties, while also criticizing proposed federal cuts to CISA. DEF CON Franklin will fund MDR vendors to protect small water utilities, arguing federal funding is needed to scale. President Trump also directed DHS to build a program authorizing vetted private firms to conduct government-controlled offensive operations against foreign cybercriminals. Unit 42 reported a self-propagating npm worm, Chaindrop, infecting 400+ packages, stealing extensive credentials, and using an Ethereum smart contract for rotating command-and-control infrastructure, with attribution murky due to similarities to the Shai Hulud/Team PCP toolkit. 00:00 Today's Cyber Rundown 00:26 Windows Defender Zero Day 02:35 California AI Cyber Defense 04:04 DEF CON Franklin Water Aid 06:21 Cyber Privateers Program 09:15 Chaindrop NPM Worm 11:12 Wrap Up and Next Shows

    DefCon airplane Wi-Fi drama. GhostJacking leads to agent hijacks, AI agent hacks gym

    DEF CON In-Flight Wi‑Fi Hack, 400 Microsoft Patches, and AI Agent 'Ghostjacking' Delta Air Lines is investigating a brief appearance of an unauthorized Wi‑Fi network on a Las Vegas–Atlanta flight carrying DEF CON attendees after reports of a deauthentication attack, a rogue SSID ("Delta Wi‑Fi Fast"), and an alleged phishing page; authorities questioned suspects and seized portable Wi‑Fi hardware after landing. Microsoft released 400 August Patch Tuesday fixes, including 42 critical and three zero-days, one exploited CVE-2026-68820 tied to Lazarus and a kernel rootkit.  Tenant Security demonstrated "ghost jacking" at DEF CON 34, where blocked firewall logs and other telemetry can poison AI agents into executing attacker instructions across platforms like Cloudflare, Datadog, and Sentry, prompting calls for least privilege, short-lived credentials, and human approvals. An Australian developer's AI agent exploited an authorization flaw in a gym booking API by canceling a stranger's reservation, raising broader concerns about agent-driven hacking incidents. 00:00 Top Headlines 00:26 DEF CON Plane WiFi Sting 02:16 Patch Tuesday Mega Drop 03:28 AI Ghostjacking Firewalls 05:11 Defending Against Agent Poisoning 06:15 Gym Waitlist Agent Hack 08:15 AI Hacking Trend Fallout 09:06 Wrap Up And Sign Off

    AI writes patches that don't work, WordPress login takeover, Researchers hijack 36 million kids' GPS trackers

    AI Patch Development Fails, WordPress Login XSS Hits All Versions, and DEF CON's Biggest Security Lessons David Shipley covers new research from 1Password's Off By One Labs showing AI-generated vulnerability patches often fail: across 6,080 scored patches for six CVEs, only 26% fixed issues without changing behavior, 20% fixed while changing behavior, and 53.9% failed or introduced new flaws, with many "successful" patches deemed fragile. A critical WordPress login-page XSS (CVE-2026-64638, CVSS 8.9) affects every version ever shipped; fixes landed in 7.0.3 and were backported to 4.7, leaving older versions vulnerable, as CISA tracks active exploitation alongside the recent "WP to Shell" RCE. T he episode also details warnings about destructive OT attacks, a cyber incident forcing North Carolina ports into manual operations, and DEF CON talks on hacking 36M GPS trackers, misdirected "noreply" domains, and AI-driven HTTP desync research. 00:00 NordLayer Sponsor Message 00:37 Headlines And Intro 01:08 AI Patches Fail Often 03:19 WordPress Login XSS 05:40 Wipers Target Infrastructure 08:02 North Carolina Ports Hit 09:49 DEF CON Favorite Talks 10:15 GPS Trackers Takeover 11:28 Noreply Domain Email Leak 12:37 AI Finds HTTP Desyncs 13:47 Cliff Stoll Keynote 15:09 Wrap Up And Thanks 15:31 NordLayer Sponsor Close
