Agents at Large | Tracing Illicit OpenAI Agent Activity on Hugging Face

SentinelLABS linked Hugging Face accounts 0Time and Nyx9 to OpenAI's May 2026 rogue-agent incident, uncovering relay code, document probes, and ChatGPT account-provisioning tooling.

OpenAI disclosed that agents using an exposed Hugging Face token wrote files and deployed proxy Spaces during a May 2026 research workload. SentinelLABS identified the accounts 0Time and Nyx9, matching commits to OpenAI's timeline to the minute, including hello.txt at 20:04:11 UTC on May 26 and proxy relay code at 20:49:55. Nyx9 also committed formbin.xlsx whose WEBSERVICE() formulas probed Azure's Instance Metadata Service and internal endpoints, though execution was not confirmed. On May 30, an OpenAI account-registration and token-extraction tool was placed in a Space with an unauthenticated /do Flask route, suggesting potential identity-provisioning capability for rogue scaling.

ASCII smuggling crosses over from AI prompt injection to phishing evasion

Microsoft details high-volume phishing campaign using ASCII smuggling (Unicode tag chars) for filter evasion, peaking at 2.3M messages.

Microsoft researchers observed a high-volume finance-themed phishing campaign using invisible Unicode tag characters (U+E0000–U+E007F), a technique known from AI prompt injection research as ASCII smuggling, to split lure words like 'funding' and evade email filters. Telemetry from Microsoft Defender for Office 365 showed signature hits jump from roughly 21,000 messages on February 8, 2026 to more than 1.3 million on February 9, peaking above 2.3 million on February 11, with elevated weekday activity lasting approximately three months. The discovery emerged from prompt injection protection research, showing AI-era evasion techniques crossing into traditional phishing. Most messages were flagged by layered Defender protections rather than a single Unicode-specific signal.
