PurpleDelta's Fraudulent Employment Operations

Executive Summary

Insikt Group has identified several clusters of activity linked to PurpleDelta, Recorded Future's designation for North Korean IT workers, comprising multiple operators likely based in China. Between late 2024 and early 2025, one cluster applied to jobs at over 1,100 companies, primarily in the software and technology, staffing and consulting, and healthcare and biotechnology sectors.

PurpleDelta operators maintained at least 22 fabricated personas across multiple clusters, some of which were supported by AI-generated profile photos, custom-configured ChatGPT assistants, and identity documents sourced from an illicit ID-generation service, and were highly likely to be actively employed by at least ten organizations.

PurpleDelta operators demonstrate a high operational tempo to this day. In some cases, the operators have applied to at least 60 positions per day across multiple job platforms, used multi-account management browsers and separate Google Chrome profiles to manage distinct personas simultaneously, and maintained detailed tracking spreadsheets to coordinate applications across identities.

During job interviews, they used screen recording software alongside AI transcription and chatbot tools to generate real-time answers, often repeating ChatGPT responses verbatim. Once employed, operators recorded internal meetings at victim organizations and used Google Translate to draft pre-written excuses to justify using personal devices and bank accounts for work.

Evidence from recorded sessions also indicates that PurpleDelta operators coordinated via Telegram and Slack, and at least two individuals were identified as facilitators who maintained company-issued hardware for the PurpleDelta operators.

Insikt Group assesses that this cluster of activity is consistent with the broader North Korean IT worker threat and presents material risk to organizations hiring for remote technical roles.
