ThreatLocker recaps August research, $190M Series F and U.K. office plans

ThreatLocker published an August recap on Sept. 3 that highlighted its cybersecurity research on AI security, ClickFix attacks, exposed infrastructure and other threats, while also noting company news including a $190 million Series F funding round and plans for a new office in Reading, U.K.

The company said the recap ties current attack techniques to older weaknesses such as trusted access and default credentials. ThreatLocker chief executive and co-founder Danny Jenkins said many of the incidents still followed familiar paths, even when AI was involved.

In the recap, ThreatLocker said it examined AI security boundaries, the risks posed by AI tools and autonomous agents, indirect prompt injection and how much access AI tools should have. The company said AI security was also a topic at Black Hat and DEF CON in Las Vegas, where Jenkins delivered a mainstage talk titled “Defending against hidden risks of AI tools in the workplace” and joined Lead Cybersecurity Engineer Kieran Human for a breakout session titled “Red teamer or AI-powered attacker? Generating, evading, and delivering malware with AI.”

ThreatLocker also said it looked at ClickFix attacks, a tactic that relies on trusted system tools such as PowerShell and Command Prompt to get users to run commands or reach the internet without enough restriction. The company said its ThreatLocker MDR team intercepted ACR Stealer delivered through ClickFix.

The recap said the company also reviewed attacks targeting water systems, default credentials in exposed infrastructure, a ShieldBreak proof-of-concept exploit from NightmareEclipse that targets the same weakness as RoguePlanet, the N-able N-central vulnerability, WiFi Pineapple hacking, and lessons for supply chain security.

On the business side, ThreatLocker said it announced a $190 million Series F round to support product innovation and global expansion. It also said it plans to open a new office in Reading, U.K., and described itself as headquartered in Orlando, Florida, with offices in Dublin, Dubai and Brisbane. The company said it protects more than 70,000 organizations worldwide.

ThreatLocker said the funding is meant to support product innovation and global expansion as it adds to its international footprint.
