GitHub Advisory malware sweep, 30 August 2026
Second wave of the grafeno-* Brazilian-fintech-themed cluster surfaced on 2026-08-30: grafeno-webhook, grafeno-payments, and grafeno-billing (all v1.0.0) reuse the 216.126.236.46 C2 host from Wave 1 but swap the x.sh + crontab mechanism for env-var scraping (AWS|TOKEN|KEY|SECRET|PASS|API) + a reverse bash shell on port 4444. Plus three CWE-506 boilerplate takedowns: quesoeducation, opiumbest, gclassroom.
