Where this verdict could be wrong1 caveat
- If this hash is a polymorphic-collision with a legitimate build, the MB label would be misleading — but MB curation makes this extremely rare.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Attempted to impair or bypass security controls.
High concern: Manipulated how the operating system loads code, which can redirect execution.
High concern: Loaded code directly into memory instead of from a normal file.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.
Threat context
How trojans work
A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything from stealing data to opening a back door or downloading more malware.
Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.
EvidenceC:\Windows\System32\svchost.exe -k NetworkService -pPE is packed (high-entropy code or known packer) AND unsigned AND at least one engine flagged it. Packing alone is common in legit software; packing + unsigned + signal is the malware-dropper pattern.
Evidencehigh-entropy code sectionSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
EvidenceC:\Windows\system32\lsass.exeThe sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
Evidence104.21.88.135 · a83f:8110:0:0:40b3:2be5:8d02:0 · 172.67.211.202Unsigned, packed PE with sandbox-observed network activity. The packing step hides the payload until execution; the network call fetches / reports for the next stage. Classic dropper / stager behaviour.

Section entropy & packers
Executable sections have high entropy (7.2+) — the code is compressed or encrypted and only decrypted at runtime. Classic packing behaviour.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.
