The threat groups Vect and TeamPCP have formally partnered since March 2026 to conduct widespread ransomware deployment and extortion campaigns by leveraging TeamPCP's credential harvesting and data theft capabilities, often initiated through supply chain compromises involving poisoned software updates and exploitation of critical vulnerabilities like CVE-2025-55182, leading to significant data exfiltration and encrypted systems across multiple sectors.

An unauthenticated remote attacker can leverage a missing authorization vulnerability (CWE-862) in the Pipecat development runner's `/ws` WebSocket endpoint to supply a crafted `callSid` in a handshake message, compelling the server to use its configured Twilio, Telnyx, or Plivo credentials to issue authenticated API requests that terminate active calls, resulting in denial of service and credential abuse.

VECT 2.0 ransomware, a RaaS offering, permanently destroys large files due to an encryption flaw, discarding decryption nonces for files above 128 KB, rendering them unrecoverable and effectively acting as a wiper; it uses raw ChaCha20-IETF with no authentication.
