Verdict Suspicious
Is Bloomclient- crackedby648k. exe. jar safe? Treat it as suspicious.
No antivirus engine detected the JAR, but conflicting sandbox labels and its cracked-tool presentation leave its intent and safety unresolved.
Read the whole reasonShow less
Why Suspicious? One sandbox test run rated it malicious while another found nothing; nothing else confirms it.
Limited evidence · One sign points to a problem; nothing else confirms it.
If it came from a link, an attachment or a stranger, delete it.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't open or run it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already opened or ran it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.
Not sure what to do?

Why we think so
4 points against it and 3 in its favour, checked against the scan evidence.
The reasoning behind this verdict
None of the 63 antivirus engines that checked it flagged the file, and no malware-specific rules, malicious files it created, or public sample-database entries corroborate the hostile sandbox label. However, the sandbox evidence conflicts, with one combined label indicating malware or a trojan and another indicating clean activity, so the file should not be trusted without further verification.
None of the 63 antivirus engines that checked it flagged the JAR, including the major engines represented in the scan. The sandbox evidence is contradictory: one combined label indicates malware or trojan activity, while another indicates clean activity. The mapping does not identify any injected process and therefore does not establish process injection. No malware-specific community rules, malicious files it created, persistence indicators, or sample-database entries corroborate the hostile label. Because the file is presented as a cracked client and was first seen on Oct 17, 2026, the clean antivirus result alone is not a sufficient benign anchor.
What We Detected
None of the 63 antivirus engines that checked it flagged this Java archive. No malware-specific community rules or public sample-database entries matched it, and none of the inspected files it created had a malicious finding.
Threat Behavior
The sandbox evidence is split: one combined label reported malware or trojan activity, while another reported clean activity. A T1055 technique mapping was present, but no injected process was recorded, so it does not demonstrate actual process injection. No sample-attributed network contact or persistence activity was recorded; the only listed address was identified as analysis-environment background traffic. A complete contacted-host reputation check is not available.
What To Do Now
Do not run the archive on a primary system or enter account credentials into it. Obtain the software from its original developer or another verifiable release channel, and keep security software enabled if further controlled testing is necessary.
Where this verdict could be wrong3 caveats
- A combined sandbox label identified malware or trojan activity, although it conflicts with a clean combined label.
- The file name presents the archive as a cracked client, an untrusted distribution context that deserves caution.
- No complete reputation result is available for contacted hosts, although the only recorded address was identified as analysis-environment background traffic.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- None of the 63 antivirus engines that checked it flagged the file.
- No malware-specific community rules or public sample-database entries matched the hash.
- No malicious file it created, persistence indicator, or sample-attributed network destination was recorded.
- The sandbox evidence conflicts, with one combined label indicating malware or trojan activity and another indicating clean activity.
- The archive is presented as a cracked client, which implies an unofficial and potentially modified distribution.
- The file has a limited observation history, first seen on Oct 17, 2026.
- A complete reputation check for contacted hosts is not available.

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Ran commands or a script on the test computer.
Moderate concern: Hid files or windows on the test computer.
Note: Read basic details of the test computer, such as its Windows version.
Note: Loaded extra code modules while running.
Note: Checked which security software was installed on the test computer.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as downloading a file, but no download was recorded.
Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.
Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
