Where this verdict could be wrong1 caveat
  • If this hash is a polymorphic-collision with a legitimate build, the MB label would be misleading — but MB curation makes this extremely rare.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Delete this Java file from the device, then empty the Recycle Bin or Trash. Run a full-system antivirus scan.

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: Created or modified a system service, which can keep code running.

  • High concern: Attempted to impair or bypass security controls.

  • Moderate concern: Contained obfuscated or packed code that makes inspection harder.

  • 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.

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.

9 evidence-based answers
Is WaterClientV6.jar a virus?
Evidence-based answer
Yes — WaterClientV6.jar is malicious. Do not open or run it. Delete this Java file from the device, then empty the Recycle Bin or Trash. 0 of 75 antivirus engines flag it (family: SilentNet). It behaves as a trojan — malware disguised as something harmless to trick you into running it. It's also a confirmed malware sample catalogued by the abuse.ch threat-intelligence community. If you've already opened or run it, see the removal and recovery steps below.
What is WaterClientV6.jar?
Evidence-based answer
WaterClientV6.jar is a Java application or archive, about 2.2 MB. Our analysis identifies it as malicious (family: SilentNet) — a trojan — malware disguised as something harmless to trick you into running it. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
How many antivirus engines detected WaterClientV6.jar?
Evidence-based answer
None — 0 of 75 antivirus engines flagged WaterClientV6.jar, but that does not make it safe: antivirus engines often miss new or targeted samples. The malicious verdict is supported by an exact-hash match in a researcher malware catalogue and the wider saved evidence.
What should I do if I already opened or ran WaterClientV6.jar?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove WaterClientV6.jar?
Evidence-based answer
To remove WaterClientV6.jar: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this Java file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is WaterClientV6.jar?
Evidence-based answer
WaterClientV6.jar is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the SilentNet family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
Has WaterClientV6.jar been seen before?
Evidence-based answer
Yes — this exact file is a known, catalogued malware sample in the abuse.ch MalwareBazaar threat-intelligence feed (tracked as SilentNet), first seen on October 4, 2026. A confirmed listing there is strong, independent evidence that the file is malicious.
What is the SHA-256 hash of WaterClientV6.jar?
Evidence-based answer
The SHA-256 hash of WaterClientV6.jar is 094af8818e148c4324e65b3a09b9c9b05a336497642fbd116037310e6b1ca8b3, and its MD5 is 63c13a0ea6cfb18c44cb01c6736e7015. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of WaterClientV6.jar?
Evidence-based answer
This report reflects the scan run on October 5, 2026. Because a file's hash never changes, the identity of WaterClientV6.jar is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
