Reasoning

This Android APK carries a single but high-confidence detection from Microsoft (tier-1) naming Wacatac, a documented banking trojan family targeting Android devices. The triggered heuristic 'DirectIpC2' flags direct-IP contact without DNS resolution, a known evasion technique to bypass reputation-based blocklists. File tags (obfuscated, detect-debug-environment, checks-gps, telephony, reflection) are consistent with Android malware anti-analysis and credential-harvesting patterns. Although only 1 of 67 engines flagged it and no sandbox verdicts confirmed malicious runtime behaviour, the combination of named-family detection, C2 evasion pattern, and obfuscation indicators converges on malicious intent. The medium prevalence (11 submitters, 2 days old) suggests a targeted or emerging sample rather than widespread commodity malware.

Key signals · 5

Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

  1. Microsoft (tier-1) flagged 'Trojan:Script/Wacatac.B!ml' — named Android banking trojan family

  2. triggeredHeuristics: DirectIpC2 fired — 18 external IPs contacted, zero domains (C2 evasion pattern)

  3. File tags: obfuscated, detect-debug-environment, checks-gps, telephony, reflection — Android malware evasion indicators

  4. Behaviour: T1071 (C2), T1406 (telephony), T1426 (system info), T1513 (clipboard) — ambient but consistent with banking trojan profile

  5. Medium prevalence (11 submitters, 2 days old) — not rare-new, but limited distribution suggests targeted or emerging sample

Points in its favour
  • No malicious sandbox verdicts recorded
  • No malicious dropped children detected
  • No contacted hosts in our malicious cache
  • 16 tier-1 engines reported clean
Points against
  • Named banking trojan family (Wacatac) detected by tier-1 engine
  • Direct-IP C2 communication (18 IPs, zero domains) — evasion pattern
  • Obfuscation and anti-debug checks present
  • Telephony and clipboard access capabilities (credential theft)
  • Unsigned APK with no publisher history
  • Medium prevalence suggests targeted or emerging sample
What to do

Block and quarantine this APK immediately. Do not install on any device. If encountered in the wild, report the source to your mobile security provider and consider notifying the app store or distribution channel.

    Sample contacted 18 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.
