ErrTraffic

Also known asErrTraffic

ErrTraffic is a cybercriminal threat cluster/service identified in the provided reporting as operating a ClickFix-as-a-Service model. Proofpoint-linked reporting described campaigns as likely conducted either by the ErrTraffic service itself or by an affiliate of ErrTraffic. The service provides ready-made infrastructure for ClickFix attacks and allows customers to deliver malware of their choice. ErrTraffic is also explicitly listed among threat clusters beyond the TA569 ecosystem that use web injects. In the cited Gizmodo incident, activity attributed to an ErrTraffic affiliate used fake CAPTCHA/ClickFix prompts delivered via a malicious script injected into a compromised website account. The prompts were tailored by operating system and attempted to trick users into manually executing terminal or PowerShell commands. On Windows, the campaign attempted to install NetSupport RAT; a separate macOS payload was prepared but appeared ineffective because it was packaged in a password-protected ZIP archive. The content does not attribute ErrTraffic to any nation state, and no additional aliases or sub-groups are provided beyond the name ErrTraffic.
