Is ATTACKSHARKX8.zip safe?
No antivirus engine detected malware, but apparent LSASS targeting and three offensive techniques create a behavioral concern that merits cautious source verification.
The archive received no detections from 75 antivirus engines, including 17 tier-1 products, and its only observed host had no cached threat match. However, one sandbox run indicated apparent LSASS targeting alongside T1485, T1548, and T1562.001, so the package should only be used if obtained from the hardware vendor’s official channel.

Before opening or extracting
Do not open or extract it until the source can be verified independently.
If you already opened or extracted it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the original trusted source and verify its exact hash when possible.
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 archive received no detections from 75 antivirus engines, including 17 tier-1 products, and its only observed host had no cached threat match. However, one sandbox run indicated apparent LSASS targeting alongside T1485, T1548, and T1562.001, so the package should only be used if obtained from the hardware vendor’s official channel.
Static scanning produced no detections from 75 antivirus engines, with all 17 tier-1 products silent. The sample is also established rather than newly observed, appearing in 360 submissions from 301 sources over 331 days. One completed sandbox run did not issue a malicious verdict, and the sole contacted domain was fully checked without a cached threat match. Against that, the runtime record includes apparent LSASS targeting and offensive techniques T1485, T1548, and T1562.001. That behavioral signal is not corroborated by engine detections, external intelligence, or a malicious dropped child, making a false alarm plausible but leaving enough uncertainty to require source verification.
What We Detected
The archive was not flagged by any of 75 antivirus engines, including 17 tier-1 products such as Avast, BitDefender, ESET-NOD32, and Kaspersky. No malware family was identified, and CIRCL, MalwareBazaar, and YARAify supplied no corroborating hit. The file has also been submitted 360 times by 301 sources over 331 days, which is more consistent with established software than a newly distributed payload.
Threat Behavior
One completed sandbox run did not produce a malicious verdict. It observed installation into an Attack Shark Software directory and contact with svc.ha-teams.office.com; the host-reputation check covered that sole observed domain and found no cached malicious or suspicious match. However, the run also produced an apparent LSASS-targeting signal and recorded T1485, T1548, and T1562.001. Those behaviors can indicate credential access, elevation, or defense impairment, although installer and peripheral-control activity can sometimes trigger broad behavioral heuristics. Eight dropped files were inspected without a malicious child finding, but their individual verdicts remain unknown.
What To Do Now
Confirm that this exact archive came from the official Attack Shark support or download channel and verify any vendor-provided checksum. Keep endpoint protection enabled, scan the extracted executables before launching them, and avoid using the package if its origin cannot be established.
Where this verdict could be wrong3 caveats
- The MalwareTips.Synth.CredentialDumper heuristic indicates apparent LSASS targeting, behavior associated with credential theft, despite the otherwise clean engine results.
- All 8 inspected dropped children have unknown individual verdicts, so hasMaliciousChild=false does not establish that those components are benign.
- T1485, T1548, and T1562.001 are offensive techniques that warrant caution even though the sandbox supplied no malicious verdict.
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 antivirus engines reported a malicious or suspicious detection.
- All 17 tier-1 engines reported no detection.
- The completed sandbox run did not issue a malicious verdict.
- The sole observed contacted domain was fully checked with no cached malicious or suspicious match.
- The sample has 360 submissions from 301 sources over 331 days.
- MalwareTips.Synth.CredentialDumper reported apparent LSASS targeting.
- Runtime evidence includes offensive techniques T1485, T1548, and T1562.001.
- All 8 dropped child files have unknown individual verdicts.
- The ZIP container has no applicable code-signing identity to authenticate its publisher.
Use the archive only if its hash and download source match the hardware vendor’s official release. Keep endpoint protection enabled and remove the package if unexpected credential-access or security-control changes occur.

What this file does
Observed actions and their security significance
High concern: Attempted to impair or bypass security controls.
Moderate concern: Removed execution artefacts or logs, which can conceal activity.
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Note: Reads your Windows user-account details.
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.
