Backblaze Responds in Minutes While reg.ru Delays Action on Banking Trojan Infrastructure
A detailed reverse-engineering report reveals a sophisticated Android banking Trojan distributed via Telegram spam that disables antivirus apps, intercepts SMS one-time codes, and exfiltrates banking credentials. The malware uses AES-encrypted assets, a custom binary protocol over sockets, and multiple modules for screen streaming, keylogging, microphone access, and remote control. Infrastructure analysis traced the payload to an S3-compatible bucket on Backblaze, four command-and-control domains, and a VPS, with the domains registered through reg.ru. Notifications sent to Backblaze resulted in account termination within 11 minutes, while reg.ru responded only after a week with a statement refusing action without a court order. The same signing certificate appears across multiple variants, allowing rapid infrastructure rotation that keeps the campaign active despite takedown attempts. Kaspersky and CERT teams were also notified but produced no visible results within the observed period.
