Big thanks to our sponsor, ThreatLocker This week, we looked at how AI is making attacks faster, less predictable, and easier to execute. But an AI-generated attack still needs permission to run, access data, use trusted applications, and move through the environment. ThreatLocker helps organizations control those actions before they become incidents. Book a demo at threatlocker.com/ciso.

Critical NetScaler vulnerability exploited in attacks AdaptHealth data breach impacts 4.1 million people MantaxOtax Android malware delivers ransomware and spyware together Get the show notes here: https://cisoseries.com/cybersecurity-news-netscaler-vulnerability-exploited-adapthealth-suffers-breach-new-android-malware/ Huge thanks to our episode sponsor, ThreatLocker AI risk does not only come from attackers. Employees are adopting AI tools faster than many organizations can evaluate them. Today's tip: an AI policy should be backed by enforceable controls over what tools can access and do. See how ThreatLocker can help you govern AI use at threatlocker.com/ciso.

Fortinet plugs two critical auth holes US says China is distilling AI at scale Mythos vulnerability hits human bottleneck Get the show notes here: https://cisoseries.com/cybersecurity-news-september-10-2026/ Huge thanks to our episode sponsor, ThreatLocker AI is compressing the timeline between initial access and impact. That leaves security teams less time to identify, investigate, and contain malicious activity. Faster response helps, but prevention can remove actions from the attack chain entirely. Give your responders a more controlled environment. Book a ThreatLocker demo at threatlocker.com/ciso.

ShinyHunters claimed it breached Florida DMV Zero-click WeChat worm spreads over incoming calls AI cheaters and whistleblowers emerge Get the show notes here: https://cisoseries.com/cybersecurity-news-florida-dmv-breach-zero-click-wechat-worm-ai-whistleblowers/  Huge thanks to our episode sponsor, ThreatLocker Attackers do not always bring their own tools. AI can help them find ways to misuse software already trusted by the organization. Today's tip: approval should not mean unlimited access. Define what trusted applications can reach and what they can do. Learn how ThreatLocker applies this principle at threatlocker.com/ciso today.

PEEP turns browsers into backdoors Liquid loses $320M, hackers play hero BigBear claws past MFA Get the full show notes here: https://cisoseries.com/cybersecurity-news-september-8-2026/ Huge thanks to our episode sponsor, ThreatLocker An attacker uses AI to create a payload your security tools have never seen. Detection now has to recognize it before the payload can act. ThreatLocker approaches the problem earlier by controlling whether that code is permitted to run at all. Explore a deny by default approach for your organization at threatlocker.com/ciso.

MikroTik routers hijacked through internet-exposed SSH Russian data centers face new security requirements UK account-hack losses surge thanks to new reporting system Get the show notes here: https://cisoseries.com/cybersecurity-news-mikrotik-routers-hijacked-russian-data-center-threats-uk-cybercrime-losses-surge/ Huge thanks to our episode sponsor, ThreatLocker AI is helping attackers research targets, create malicious code, and adapt faster. But the fundamentals have not changed. Code still needs to execute, applications still need access, and attackers still need privileges. Today's tip: control those actions instead of trying to predict every threat. Learn more from ThreatLocker at threatlocker.com/ciso.

Dark web shop stocks 153 million driver's licenses Nexus, a new dark web service, claims it's selling scans of more than 153 million US and Canadian driver's licenses, plus over 10 million ID cards, three million travel and international IDs, and at least 579,000 medical cards. The images appear tied to Louisiana-based IDScan.net, which provides identity verification to retailers, rental-car companies, and others. KrebsOnSecurity matched some records to licenses scanned during Hertz rentals. IDScan says it's investigating and hasn't determined the breach's nature or scope. The FBI's New Orleans office has opened an inquiry.

Under new Enterprise Frontier Safeguards, customers can keep data in their own cloud and block Anthropic employees from reviewing it while automated abuse monitoring continues. Anthropic calls that privacy equivalent to zero data retention. Developed with more than 100 customers, including Salesforce, the system is due later this year. (CNBC) Astra enters OpenAI's cyber red zone OpenAI says Astra is its first model to reach a "Critical" cybersecurity threshold, meaning it can find unknown flaws and build exploits across well-defended systems without step-by-step human help. It's due soon, but the advanced cyber capabilities will start with a small test group before expanding through Daybreak Blue. OpenAI says Astra refused 91.5% of cyber jailbreak requests, versus 59% for GPT-5.6 Sol, and monitoring can pause suspicious activity. The Information reports Astra's latent reasoning may hide parts of its process, raising doubts about chain-of-thought monitoring.
