Is CitizenMP.exe safe?
One of 74 engines detected ShellcodeRunner, while verified Rockstar Games signing, mature prevalence, and complete tier-1 silence strongly favor a false alarm.
The executable has verified Rockstar Games signing and has circulated broadly for nearly three years, with only Zillya flagging it among 74 engines. Sandbox telemetry includes process-injection and LSASS-related indicators, but it produced no malicious runtime verdict, and the observed IP contacts were not reputation-checked completely.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
The executable has verified Rockstar Games signing and has circulated broadly for nearly three years, with only Zillya flagging it among 74 engines. Sandbox telemetry includes process-injection and LSASS-related indicators, but it produced no malicious runtime verdict, and the observed IP contacts were not reputation-checked completely.
Zillya supplied the only detection among 74 engines, and none of the 17 tier-1 engines flagged the sample. The executable carries a verified Rockstar Games signature with no detected brand conflict. Its 14,250 submissions from 3,741 sources over 1,070 days are inconsistent with a narrowly distributed new threat. One sandbox mapped several concerning techniques, including process injection and LSASS-related activity, but did not issue a malicious verdict or identify a malicious dropped child. Because host-reputation coverage is unavailable for the observed IP traffic, that portion remains unresolved rather than clean.
What We Detected
Zillya was the sole detector among 74 engines, labeling the executable as ShellcodeRunner. All 17 tier-1 engines reported it clean, and there was no multi-engine family consensus. The file has a verified Rockstar Games signature, no detected brand mismatch, and extensive established prevalence with 14,250 submissions from 3,741 sources.
Threat Behavior
One sandbox run mapped ten offensive techniques, including T1055.003 process injection, and recorded LSASS-related process activity. It did not produce a malicious sandbox verdict, and none of ten inspected dropped children was identified as malicious, though their individual verdicts remain unknown. The sample contacted multiple IP addresses, but no complete host-reputation result is available, so those connections cannot be characterized as benign or malicious.
What To Do Now
Use a copy obtained through the official FiveM or Rockstar-associated release channel and verify that the digital signature remains valid before running it. Keep endpoint protection enabled; quarantine and investigate if the signature is invalid, the hash differs, or unexpected credential-access or persistence activity appears.
Where this verdict could be wrong4 caveats
- The completed sandbox mapped ten offensive techniques, including T1055.003, and a heuristic associated process activity with LSASS; these observations warrant caution despite lacking a malicious sandbox verdict.
- Zillya labeled the sample 'Trojan.ShellcodeRunner.Win64.8355', although no other engine corroborated that family.
- contactedHosts=null leaves the observed direct-IP traffic without a complete host-reputation result.
- signing.signerStats.totalSamples=1 provides only a small historical sample for the signer.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Only 1/74 engines detected the file.
- All 17 tier-1 engines reported clean.
- The Rockstar Games digital signature is verified.
- The file has 14,250 submissions from 3,741 sources over 1,070 days.
- No inspected dropped child was identified as malicious.
- Sandbox telemetry mapped T1055.003 process injection.
- Heuristic evidence associated process activity with LSASS.
- Ten offensive MITRE techniques were recorded in one sandbox.
- Multiple direct IP contacts lack a complete reputation cross-check.
- Zillya reported Trojan.ShellcodeRunner.Win64.8355.
Prefer the official distribution channel and confirm the Rockstar Games signature and SHA-256 before execution. Keep endpoint protection enabled and investigate any unexpected credential-access behavior.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
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\Explorer.EXESandbox 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.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
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.
