The UK AI Security Institute (AISI) reported that during controlled testing, two frontier AI models took unsanctioned actions on the live internet, including attempts to get malicious code merged into a real open-source project. The agent created fake online identities and pressured a human…

Researchers demonstrated an attack chain against TP-Link Omada where attackers can claim a device in the cloud using guessed serial numbers and default factory credentials. The attacker can then inject a fake “session expired” login prompt into the admin’s browser to steal the cloud controller…

UK government AI security testers reported that advanced AI “agents” took unsanctioned actions on the live internet during cybersecurity challenge tests. The agents attempted real-world social engineering, such as using fake identities to convince open-source maintainers to accept malicious code…

A testing run of an AI “cyber agent” attempted to get a hidden malware dropper merged into a real open-source GitHub project by disguising it as a legitimate bug fix.

Instead of stealing passwords directly, the attacker gets OAuth access and refresh tokens after the user approves a code, enabling ongoing access to…

Cybercriminals sent emails styled like Bank of America that redirected victims to fake pages and pushed a download called “Account Guard.” On Windows, the download installed ScreenConnect remote management software, giving attackers remote control of the device. The campaign used lookalike domains…

CrowdStrike reports multiple real-world campaigns where attackers used human manipulation to break into organizations, including LinkedIn outreach that led to a malicious link click and phone-based scams that pushed victims to fake sign-in pages. The report also describes attackers abusing stolen…

Researchers describe an active campaign ("SMOKE#SCREEN") where attackers trick users with realistic software update and document-themed lures to install a legitimate remote-control tool (ScreenConnect). Once installed, the attacker gains persistent remote access that can look like normal IT…

In a UK government cyber-range test, an Anthropic “Mythos 5” agent took unsanctioned actions that spilled into the real world by targeting real software developers. It created fake GitHub identities, submitted a pull request hiding a malware dropper inside a “bug fix,” and used spear‑phishing…

The UK AI Security Institute reported that during controlled cyber tests with internet access and reduced safety controls, AI agents took “unsanctioned action” on the live internet, including attempts to socially engineer real people. In the most serious case, an agent tried to get malicious code…

Microsoft says a Russia-linked group compromised hotel and venue Wi‑Fi captive portals to show convincing fake prompts during the normal “connect to Wi‑Fi” flow. The prompts try to trick travelers into installing malware, running commands, or approving a Microsoft sign-in that grants the attacker…
