Extended Dwell Time Impact

For 1+ days, this malware remained undetected — a brief but concerning window that permitted the adversary to establish initial foothold, perform basic system enumeration, and potentially access immediate system resources.

Comparative Context

Industry studies report a median dwell time closer to 21–24 days. This case is significantly below that median, suggesting relatively quick detection.

Timeline

Time (UTC) Event Elapsed
2025-08-25 17:22:10 UTC First VirusTotal submission
2025-11-19 12:50:06 UTC Latest analysis snapshot 85 days, 19 hours, 27 minutes
2025-11-20 08:40:36 UTC Report generation time 86 days, 15 hours, 18 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: 73. Detected as malicious: 56. Missed: 17. Coverage: 76.7%.

Detected Vendors

  • Xcitium
  • +55 additional vendors (names not provided)

List includes Xcitium plus an additional 55 vendors per the provided summary.

Missed Vendors

  • Acronis
  • Antiy-AVL
  • APEX
  • Baidu
  • Bkav
  • ClamAV
  • CMC
  • Gridinsoft
  • Jiangmin
  • SUPERAntiSpyware
  • TACHYON
  • tehtris
  • Trapmine
  • VBA32
  • VirIT
  • Yandex
  • 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.

Behavioral Storyline — How the Malware Operates

Dominant system-level operations (67.23% of behavior) suggest this malware performs deep system reconnaissance, privilege escalation, or core OS manipulation. It’s actively probing system defenses and attempting to gain administrative control.

Behavior Categories (weighted)

Weight values represent the frequency and intensity of malware interactions with specific system components. Higher weights indicate more aggressive targeting of that category. Each operation (registry access, file modification, network connection, etc.) contributes to the category’s total weight, providing a quantitative measure of the malware’s behavioral focus.

Category Weight Percentage
System 80 67.23%
File System 14 11.76%
Process 11 9.24%
Device 6 5.04%
Misc 4 3.36%
Hooking 2 1.68%
Registry 2 1.68%

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.

What To Do Now — Practical Defense Playbook

  • Contain unknowns: block first‑run binaries by default — signatures catch up, containment works now.
  • EDR controls: alert on keyboard hooks, screen capture APIs, VM/sandbox checks, and command‑shell launches.
  • Registry watch: flag queries/sets under policy paths (e.g., …\FipsAlgorithmPolicy\*).
  • Network rules: inspect outbound TLS to IP‑lookup services and unexpected CDN endpoints.
  • Hunt broadly: sweep endpoints for the indicators above and quarantine positives immediately.

Dwell time equals attacker opportunity. Reducing execution privileges and egress shrinks that window even when vendors disagree.
