Is JJBotv3.exe safe?
A completed sandbox produced a malware verdict, requiring caution despite zero antivirus detections, only ambient techniques, and no corroborating family or hostile domain evidence.
A completed sandbox marked the executable as malware, which outweighs the otherwise reassuring static scan under the applicable safety rule. However, 0 of 75 engines detected it, another sandbox result was clean, and no malware family or offensive technique was identified, so the finding has substantial false-positive potential.

Before running
Do not run it. Delete this file from the device, then empty the Recycle Bin or Trash.
If you already ran it
Disconnect from the internet, start a full or offline antivirus scan, then secure important accounts from a clean device.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
A completed sandbox marked the executable as malware, which outweighs the otherwise reassuring static scan under the applicable safety rule. However, 0 of 75 engines detected it, another sandbox result was clean, and no malware family or offensive technique was identified, so the finding has substantial false-positive potential.
The decisive concern is behaviour.hasMaliciousSandboxVerdict=true from a completed runtime analysis. Static scanning is strongly reassuring, with 0 of 75 engines flagging the file and all 17 reporting tier-1 engines returning no detection. Runtime details show seven ambient techniques but no malware-exclusive techniques, persistence, written files, or dropped hashes. Both observed domains were checked and had no malicious or suspicious cache findings, although the contacted IPs lacked equivalent coverage. Because the runtime verdict conflicts with the engine results and lacks family-level corroboration, confidence remains moderate and the sample should be handled cautiously pending another isolated analysis.
What We Detected
One completed sandbox result marked the executable as malware, while another recorded sandbox result was clean. At the same time, 0 of 75 antivirus engines detected the sample, including 17 reporting tier-1 engines.
Threat Behavior
The runtime record contains seven ambient MITRE techniques, including T1059 and T1497.001, but behaviour.offensiveCount=0. No persistence indicators, written files, or dropped hashes were recorded. The two contacted domains—res.public.onecdn.static.microsoft and www.microsoft.com—were fully checked and had no malicious or suspicious cache findings; the listed IP addresses were not covered by that check.
What To Do Now
Do not run the executable on a production system while the conflicting runtime result remains unresolved. Keep endpoint protection enabled, verify the file's source and hash, and obtain a fresh sandbox analysis or a known-good copy from the original publisher.
Where this verdict could be wrong4 caveats
- The antivirus results are uniformly non-detecting: 0/75 engines flagged the executable, including all 17 reporting tier-1 engines.
- The runtime verdicts conflict: sandboxVerdicts records one malicious result and one clean result.
- The file is unsigned (signing.signed=false), but unsigned status alone does not establish harmful behavior.
- Host-reputation coverage included both contacted domains but not the 11 entries in behaviour.contactedIps, so the network cross-check was incomplete overall.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/75 engines detected the file
- engines.tier1ReportedClean=17 and tier1Malicious=0
- behaviour.offensiveCount=0
- contactedHosts found no malicious or suspicious result for both contacted domains
- externalIntel.yaraify.ruleCount=0 and MalwareBazaar hit=false
- behaviour.hasMaliciousSandboxVerdict=true
- Conflicting runtime verdicts: one malicious and one clean
- signing.signed=false for a Win32 executable
- T1497.001 indicates virtualization or sandbox awareness
- No complete reputation coverage for behaviour.contactedIps
Quarantine the file and avoid executing it on production devices until its source is verified and an independent isolated run resolves the conflicting sandbox results. Keep endpoint protection enabled.

What this file does
Observed actions and their security significance
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: Checked the environment for virtualisation or analysis tools.
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.
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.
