Is Setup.exe safe?
A corroborated crack-tool classification, seven tier-1 detections, and possible T1055 process injection make this unsigned installer unsafe to execute.
The executable drew detections from 27 of 74 engines, including seven tier-1 engines, and its crack-tool label is independently corroborated. One sandbox also recorded activity mapped to T1055 process injection; avoid running it and obtain the software only through its legitimate publisher.

If you already installed it
Disconnect from the internet, start a full or offline antivirus scan, then secure important accounts from a clean device.
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.
The executable drew detections from 27 of 74 engines, including seven tier-1 engines, and its crack-tool label is independently corroborated. One sandbox also recorded activity mapped to T1055 process injection; avoid running it and obtain the software only through its legitimate publisher.
Detection volume is substantial: 27 of 74 engines flagged the executable, including seven tier-1 engines. ESET-NOD32 explicitly identified a Crack hacktool, while Fortinet and several other engines independently used Crack, riskware, or trojan labels. A completed sandbox recorded activity mapped to MITRE T1055, which supports concern about possible process injection, although the sandbox itself did not issue a malware verdict. The executable is unsigned and lacks an established publisher history. The direct-IP connection has not received a complete host-reputation check, so its no complete contacted-host reputation result was available or malicious from the available evidence.
What We Detected
Twenty-seven of 74 antivirus engines flagged this unsigned Windows executable, including seven tier-1 engines. ESET-NOD32 identified Win32/HackTool.Crack.ES, Fortinet reported Riskware/Crack, and additional engines used crack, hacktool, or trojan labels. The hacktool identification is corroborated rather than resting on one low-trust detector.
Threat Behavior
One completed sandbox run recorded behavior mapped to MITRE T1055, indicating possible process injection. It also observed a connection to 162.159.36.2; however, no complete host-reputation cross-check is available for that address, so the connection alone cannot be characterized as command-and-control. No malicious dropped child was confirmed, but all ten inspected children remain unclassified.
What To Do Now
Do not execute the installer. Delete or quarantine it while keeping endpoint protection enabled, and obtain the intended application from the publisher's official release channel. If it already ran, perform a full security scan and review the system for unexpected processes, software, and account activity.
Where this verdict could be wrong5 caveats
- engines.tier1FamilyConsensus is not strong: only 2 engines agree on Crack, while other tier-1 labels are generic or name differing trojans.
- behaviour.hasMaliciousSandboxVerdict=false, and all 10 inspected dropped children remain unclassified rather than confirmed malicious.
- externalIntel.yaraify.ruleCount=0 and externalIntel.circl.hit=false provide no researcher-curated corroboration.
- PE analysis reports peAnalysis.highEntropyCode=false and peAnalysis.likelyPacked=false.
- The one safe similar-hash verdict is an imphash-only match with signerCoMatch=false, so it may reflect an installer-framework collision.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No completed sandbox issued a malicious verdict
- No inspected dropped child was confirmed malicious
- No strong tier-1 family consensus was established
- No YARAify or CIRCL hit was present
- Static PE analysis found neither high-entropy code nor likely packing
- 27 of 74 antivirus engines reported malicious or unwanted content
- Seven tier-1 engines flagged the executable
- Corroborated Crack hacktool classification
- Possible process injection mapped to MITRE T1055
- Unsigned executable with no publisher history
- Direct-IP contact to 162.159.36.2 without a completed reputation check
Do not run this installer; quarantine or remove it while keeping endpoint protection enabled. If execution already occurred, run a full scan and replace it with a copy from the legitimate publisher.

What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal 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: Reads your Windows user-account details.
Note: Listed running processes; both legitimate software and malware may do this.
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.
Threat context
How hacktools are abused
This is a hacking or cracking tool — the kind used to bypass software licences, generate fake keys, or attack other systems. Even when the tool 'works', these downloads very often carry hidden malware.
Bottom line:Running one means trusting an anonymous author with full access to your PC — rarely worth the risk.

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:\Users\<USER>\AppData\Local\Temp\is-BLJ0S.tmp\Setup.tmp /SL5=$1100E8,8572006,153088,C:\Users\<USER>\Downloads\Setup.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.
