Is content.js safe?
No antivirus engine detected this script, but inconclusive sandbox mappings to process injection and LSASS activity justify caution pending direct code review.
All 76 antivirus engines were free of detections, including 17 tier-1 engines, and no malicious sandbox verdict or known-malware intelligence was recorded. However, one sandbox mapped activity to T1055 and LSASS-related behavior; because those findings derive from process entries rather than demonstrated injection or memory access, they are concerning but not conclusive.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 76 antivirus engines were free of detections, including 17 tier-1 engines, and no malicious sandbox verdict or known-malware intelligence was recorded. However, one sandbox mapped activity to T1055 and LSASS-related behavior; because those findings derive from process entries rather than demonstrated injection or memory access, they are concerning but not conclusive.
The strongest evidence is the absence of detections across 76 antivirus engines, including all 17 participating tier-1 engines. One completed sandbox run did not issue a malicious verdict and observed no contacted domains, IPs, or URLs. It nevertheless mapped activity to T1055 and raised an LSASS-related heuristic, but the stored evidence only lists ordinary system process command lines and does not prove injection or credential access. Research intelligence supplied no matching YARA rules or known-malware records. The dropped child remains unclassified, and no saved host-reputation cross-check is available, leaving enough uncertainty to recommend caution rather than unconditional trust.
What We Detected
None of 76 antivirus engines flagged the 2,055-byte JavaScript file, and all 17 participating tier-1 engines reported no detection. Research intelligence also returned no matching YARA rules or known-malware records.
Threat Behavior
One completed sandbox run mapped activity to MITRE T1055 and raised an LSASS-related credential-access heuristic. However, the retained evidence consists of process entries for svchost.exe and lsass.exe; it does not establish that the script injected code or read process memory. The sandbox issued no malicious verdict and recorded no network contacts. One dropped child was inspected but remained unclassified, while no complete host-reputation result was saved.
What To Do Now
Do not execute the script directly with Windows Script Host unless its source and purpose are trusted. Review its JavaScript contents, test it in an isolated environment, and keep endpoint protection enabled.
Where this verdict could be wrong3 caveats
- The runtime mapping includes MITRE T1055, which can indicate process injection and warrants caution despite the absence of engine detections.
- MalwareTips.Synth.CredentialDumper associates the process list with LSASS, although the evidence does not prove that LSASS memory was read.
- The one dropped child was not fully classified, and contactedHosts=null means no saved host-reputation cross-check is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/76 antivirus engines reported a detection.
- All 17 participating tier-1 engines reported no detection.
- behaviour.hasMaliciousSandboxVerdict=false.
- externalIntel.yaraify.ruleCount=0 and externalIntel.malwareBazaar.hit=false.
- droppedChildren.hasMaliciousChild=false.
- One sandbox mapped the execution to MITRE T1055.
- An LSASS-related credential-dumper heuristic fired.
- The dropped child remained unclassified.
- No complete contacted-host reputation result is available.
Quarantine the script until its source code and origin are verified, then test only in an isolated environment if execution is necessary. Keep endpoint protection enabled.

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: Manipulated how the operating system loads code, which can redirect execution.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Note: Collects details about your system.
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.

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\System32\svchost.exe -k NetworkService -pSandbox observed process activity targeting LSASS (Windows credential store). Legitimate software has no business reading LSASS memory — this is Mimikatz-shape behaviour.
