Zero‑Dwell Threat Intelligence Report

A narrative, executive‑ready view into the malware’s behavior, exposure, and reliable defenses.

Executive Overview — What We’re Dealing With

This specimen has persisted long enough to matter. Human experts classified it as Malware, and the telemetry confirms a capable, evasive Trojan with real impact potential.

Dwell Time
883 days 5 hours 35 minutes

Extended Dwell Time Impact

For 883+ days, this malware remained undetected — an extremely prolonged compromise that provided the adversary extensive opportunity for advanced persistent operations, comprehensive data harvesting, lateral movement across network segments, and sophisticated evasion technique deployment.

Comparative Context

Industry studies report a median dwell time closer to 21–24 days. This case meets or exceeds that benchmark, highlighting a significant detection gap.

Timeline

Time (UTC) Event Elapsed
2023-11-15 15:28:33 UTC First VirusTotal submission
2026-06-09 10:45:50 UTC Latest analysis snapshot 936 days, 19 hours, 17 minutes
2026-06-26 06:23:21 UTC Report generation time 953 days, 14 hours, 54 minutes

Why It Matters

Every additional day of dwell time is not just an abstract number — it is attacker opportunity. Each day equates to more time for lateral movement, stealth persistence, and intelligence gathering.

Global Detection Posture — Who Caught It, Who Missed It

VirusTotal engines: 69. Detected as malicious: 52. Missed: 17. Coverage: 75.4%.

Detected Vendors

  • Xcitium
  • +51 additional vendors (names not provided)

List includes Xcitium plus an additional 18 vendors per the provided summary.

Missed Vendors

  • Acronis
  • APEX
  • CMC
  • Elastic
  • google_safebrowsing
  • Gridinsoft
  • Jiangmin
  • MaxSecure
  • SentinelOne
  • SUPERAntiSpyware
  • TACHYON
  • tehtris
  • Trapmine
  • Webroot
  • Zillya
  • ZoneAlarm
  • Zoner

Why it matters: if any endpoint relies solely on a missed engine, this malware can operate with zero alerts. Prevention‑first controls close that gap regardless of signature lag.

Following the Trail — Network & DNS Activity

Outbound activity leans on reputable infrastructure (e.g., CDNs, cloud endpoints) to blend in. TLS sessions and
HTTP calls show routine beaconing and IP‑lookup behavior that can masquerade as normal browsing.

Hunting tip: alert on unknown binaries initiating TLS to IP‑lookup services or unusual CDN endpoints — especially early in execution.
