PUBLIC-SAFE RUN REPORT
Yoba / Fake AI Desktop Installer Campaign — Malware & Campaign Intelligence
Verified Findings
None
Contradictions / Caveats
- UNKNOWN: Check Point Research documented the Yoba Windows malware campaign using fake GitHub/GitHub Pages AI-app lures, signed OpenAI/Anthropic binaries for DLL sideloading, a YobaDropper→YobaLoader chain, public-service-based tasking and an observed XMRig final payload.
- Evidence boundary: Victim count, prevalence, intentional geotargeting, named actor identity, non-XMRig deployment or upstream vendor compromise.
- UNKNOWN: On 2026-11-01, direct GitHub API requests for three named Yoba lure repositories returned HTTP 404 / Not Found.
- Evidence boundary: Formal takedown, campaign termination, reason for unavailability, absence of replacement infrastructure or absence of prior victimization.
Open Follow-up
- OPEN [HIGH]: VICTIM_SCALE_CURRENT_ACTIVITY — No confirmed victim count, normalized infection telemetry, independent live EDR/IR validation, or proof that the originally named Yoba lure repositories remain active or have been replaced.
- OPEN [HIGH]: ATTRIBUTION_TARGETING — Actor identity and intentional geographic targeting for Yoba remain unresolved; CIS keyboard exclusions and inconsistent timezone clues do not establish either.
