Jackskid is a Mirai-derived Linux/IoT DDoS botnet, first publicly documented by Foresiet in November 2025 and tracked by CNCERT/SecrSS as RCtea. It encrypts its configuration with a custom RC4 cipher post-processed by an LCG (key DEADBEEF CAFEBABE E0A4CBD6 BADC0DE5) and negotiates per-session ChaCha20 keys via XXTEA (passphrase FrshPckBnnnSplit). The same RC4+LCG modification appears in Aisuru, indicating a shared code lineage, and the family sits within the CatDDoS-derivative ecosystem. Later builds add ENS-based C2 resolution, an anti-competition module (0clKiller) backed by a NETLINK process monitor, and a pivot toward Android/ADB-exposed TV boxes. Jackskid and several related botnets were disrupted by law enforcement in March 2026.
