Is 67ClientCrackedByDexter .jar safe?
No antivirus engine identified malware, but runtime mappings for process injection and defense impairment warrant caution with this unofficially named Java archive.
All 74 antivirus engines avoided flagging this JAR, including 17 tier-1 engines, and curated intelligence produced no malware match. However, one sandbox mapped activity to process injection and defense impairment, while four dropped files remain unresolved, so the archive should not be trusted solely from the clean detection count.

Before opening or running
Do not open or run it until the source and publisher can be verified independently.
If you already opened or ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the publisher's official site and verify its exact hash when possible.
Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
All 74 antivirus engines avoided flagging this JAR, including 17 tier-1 engines, and curated intelligence produced no malware match. However, one sandbox mapped activity to process injection and defense impairment, while four dropped files remain unresolved, so the archive should not be trusted solely from the clean detection count.
The strongest evidence is the absence of detections across all 74 engines, including 17 tier-1 products. One completed sandbox run did not issue a malicious verdict or record network contacts, but it mapped activity to T1055 and T1562.001. Those mappings are concerning, although the process-injection heuristic explicitly does not establish the exact method or intent. Four dropped children were inspected without a confirmed malicious result, but each remains unclassified rather than proven benign. Curated intelligence sources supplied no family identification or matching rules, and no complete contacted-host reputation result is available.
What We Detected
None of 74 antivirus engines flagged the Java archive, including 17 tier-1 engines. Curated intelligence checks also returned no MalwareBazaar family, CIRCL match, or YARAify rule hit. The sample has been submitted 308 times by 256 sources, providing moderate exposure without a known threat label.
Threat Behavior
One completed sandbox run mapped activity to T1055 (Process Injection) and T1562.001 (Impair Defenses). These are meaningful risk indicators, but the sandbox did not issue a malicious verdict, and the available mapping does not prove the exact injection technique or intent. No network contacts were recorded during that run; contacted-host reputation was not checked or saved. Four dropped files were inspected with no confirmed malicious child, although all four remain unclassified.
What To Do Now
Treat the archive cautiously because its filename suggests an unofficial cracked distribution and its runtime mappings include offensive techniques. Prefer an authentic release from the original developer, keep endpoint protection enabled, and avoid running this copy on a primary system or with sensitive accounts.
Where this verdict could be wrong4 caveats
- The saved runtime mapping includes T1055 process injection and T1562.001 impairment of defenses, techniques associated with offensive activity even though no engine or sandbox issued a malware finding.
- All four dropped children have unknown verdicts, so droppedChildren.hasMaliciousChild=false does not establish that those files are benign.
- contactedHosts=null means no complete host-reputation result is available; however, the sandbox recorded no domains, IP addresses, or URLs to cross-check.
- The filename indicates a cracked client, which suggests an unofficial or modified distribution even though it is not independently corroborated as malware.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 antivirus engines reported a malicious or suspicious detection.
- 17 tier-1 engines reported no detection.
- behaviour.hasMaliciousSandboxVerdict=false in one completed sandbox run.
- externalIntel.yaraify.ruleCount=0 and both CIRCL and MalwareBazaar returned no hit.
- droppedChildren.hasMaliciousChild=false across 4 inspected files.
- behaviour.offensiveTechniques includes T1055 process injection.
- behaviour.offensiveTechniques includes T1562.001 impairment of defenses.
- The filename suggests an unofficial cracked or modified client.
- All 4 inspected dropped children remain unknown.
- contactedHosts=null leaves host-reputation coverage unavailable.
Do not use this unofficial cracked copy; obtain the software from its original developer or another verified release channel. Keep endpoint protection enabled and isolate the archive if further testing is necessary.

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.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Transferred a file over the network; malware can use this to fetch additional payloads.
Moderate concern: Checks which security software you have installed.
Note: Collects details about your system.
Note: Loads extra code modules while running.
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.

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.
