Is 13211621092027.VHDX safe?
Two tier-1 engines flagged this newly observed VHDX, but family disagreement and absent runtime or external corroboration leave the threat identity unresolved.
Three of 74 engines detected the file, including two independent tier-1 engines, so it should not be opened or mounted casually. Only ESET-NOD32 identified Valley, while Ikarus used a generic trojan label; no runtime analysis or complete network-reputation check is available to resolve the disagreement.

Before opening
Do not open it until the source can be verified independently.
If you already opened 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.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
Three of 74 engines detected the file, including two independent tier-1 engines, so it should not be opened or mounted casually. Only ESET-NOD32 identified Valley, while Ikarus used a generic trojan label; no runtime analysis or complete network-reputation check is available to resolve the disagreement.
The strongest concern is that two independent tier-1 engines flagged the sample among 3 of 74 detections. ESET-NOD32 named Valley, but Ikarus supplied a generic Crypt trojan label, leaving no strong family consensus. The VHDX is newly observed with only one submission, so prevalence cannot establish legitimacy. Conversely, 15 tier-1 engines did not detect it, and researcher-curated intelligence produced no corroborating hit. Because no completed runtime observation or complete contacted-host reputation result is available, the evidence supports caution without establishing a specific malware family.
What We Detected
Three of 74 antivirus engines flagged the VHDX. Two are tier-1 detections: ESET-NOD32 reported Win32/Valley.J trojan, while Ikarus reported Trojan.Win32.Crypt; Google supplied a nonspecific detection. Only one engine named Valley, so the family attribution is not independently confirmed.
Threat Behavior
No completed sandbox observation is available, so execution, persistence, payload delivery, and other runtime behavior were not observed. The contacted-host reputation cross-check was also unavailable, meaning no complete network-risk conclusion can be drawn. No malicious dropped child was reported, but the dropped-children block itself is absent.
What To Do Now
Do not mount, boot, or extract this VHDX on a production system. Keep endpoint protection enabled, quarantine the file, verify its source and expected hash, and use an isolated analysis environment if examination is necessary.
Where this verdict could be wrong3 caveats
- 15 of 17 reporting tier-1 engines did not flag the sample, including Microsoft, Kaspersky, BitDefender, Avast, and Fortinet.
- externalIntel.malwareBazaar.hit=false, externalIntel.yaraify.ruleCount=0, and externalIntel.circl.hit=false provide no independent malicious corroboration, although absence of a hit does not prove benignity.
- The two tier-1 detections disagree on a specific family: only ESET-NOD32 names Valley, while Ikarus uses a generic cryptic-trojan label.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 15 of 17 reporting tier-1 engines did not flag the sample
- No strong tier-1 family consensus
- No MalwareBazaar, YARAify, or CIRCL hit
- No brand mismatch detected
- No confirmed hacktool or test-file labeling
- Two independent tier-1 antivirus detections
- Three detections among 74 engines
- Newly observed sample with one submission
- VHDX contents were not validated through runtime observation
- No complete contacted-host reputation result
- No verified publisher identity applies to this file type
Quarantine the VHDX and avoid mounting or booting it until its origin and hash are verified. Keep endpoint protection enabled and inspect it only in a properly isolated environment.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. 3 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.
