Is BongoCat_1.1.0_x64-setup.exe safe?
This unsigned installer exhibits suspicious process injection and credential-dumping behavior, indicating it is likely a malicious trojan masquerading as legitimate software.
Our analysis identified this file as malicious due to its lack of a digital signature and observed high-risk runtime behaviors. Specifically, the installer attempted process injection and targeted the Windows credential store (LSASS), which are common indicators of credential-stealing malware.

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.
Our analysis identified this file as malicious due to its lack of a digital signature and observed high-risk runtime behaviors. Specifically, the installer attempted process injection and targeted the Windows credential store (LSASS), which are common indicators of credential-stealing malware.
The file is unsigned and lacks a verified publisher, which is highly unusual for a legitimate software installer. During sandbox execution, the file performed process injection and attempted to access the LSASS process, which is a critical security violation. While engine detection is currently low, these behavioral signals are strongly indicative of malicious intent. Similar files sharing this installer framework have consistently been flagged as suspicious in our database.
What We Detected
The file BongoCat_1.1.0_x64-setup.exe is an unsigned executable that attempts to perform unauthorized system operations. While it presents as a standard installer, our analysis detected high-risk behaviors including process injection (MITRE T1055) and attempts to access the Windows Local Security Authority Subsystem Service (LSASS) process (MITRE T1134).
Threat Behavior
The file's attempt to interact with lsass.exe is a classic indicator of credential-dumping activity, often associated with tools like Mimikatz. Furthermore, the process injection observed during execution suggests the file is attempting to hide its activity or escalate privileges within the system. These behaviors are not consistent with a legitimate software installer.
What To Do Now
Do not execute this file. If you have already run it, we strongly recommend performing a full system scan with reputable security software, changing your saved passwords, and monitoring your accounts for unauthorized access. Remove the file and any associated directories created in C:\Program Files\BongoCat.
Where this verdict could be wrong2 caveats
- Only 1 of 75 engines flagged the file, which could suggest a false positive or a very new, undetected threat.
- The file has a medium prevalence (335 submissions), which is relatively high for a malicious sample, though this may reflect widespread distribution of a compromised installer.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- unsigned executable
- process injection (T1055)
- LSASS access attempt (T1134)
- similar hashes flagged as suspicious
- installer framework imphash collision
Delete the file immediately and do not run it. If already executed, perform a full system scan and reset your credentials.

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: Changed an auto-start location that can make code run after sign-in or restart.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Scans through your files and folders.
Moderate concern: Checks which security software you have installed.
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.

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.
