Slow Pisces, also known as Jade Sleet, TraderTraitor, or PUKCHONG, is described as a North Korean state-sponsored group targeting cryptocurrency developers through recruiter impersonation on LinkedIn. The campaign sent job descriptions and coding challenges that led victims to GitHub repositories adapted from legitimate Python, JavaScript, and occasional Java projects, with malicious behavior hidden in otherwise plausible developer tasks. In Python repositories, a Slow Pisces-controlled endpoint such as en.stockslab.org returned benign-looking data to most requests but could deliver YAML payloads to validated targets, abusing unsafe PyYAML yaml.load() deserialization. The payload chain created ~/Public/__init__.py, executed RN Loader, communicated with the same C2 over HTTPS, and could deliver RN Stealer or other payloads through a command loop. The activity matters because it shows a controlled, developer-focused infection chain aligned with DPRK cryptocurrency theft operations and includes payload hashes for detection.
