Is Bookworm-Adventures_Win_EN_Rip.zip safe?
Only Kingsoft flagged this longstanding, widely submitted archive, while tier-1 engines, sandbox verdicts, dropped-child checks, and researcher intelligence supplied no malware corroboration.
One of 74 antivirus engines flagged the archive with a generic label, while no tier-1 engine detected it. Its long circulation history and lack of corroboration support a likely isolated false positive, although direct-IP traffic and T1562.001 justify obtaining the game from a reputable source.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
One of 74 antivirus engines flagged the archive with a generic label, while no tier-1 engine detected it. Its long circulation history and lack of corroboration support a likely isolated false positive, although direct-IP traffic and T1562.001 justify obtaining the game from a reputable source.
The archive received one generic Kingsoft detection among 74 engines, with no tier-1 detections or family consensus. It has circulated for more than three years across 159 sources and 173 submissions, which weighs against a newly distributed threat. One completed sandbox run did not produce a malicious conclusion, and no inspected child was identified as malicious. However, runtime evidence included T1562.001 and two direct-IP contacts, and no complete host-reputation result is available for those addresses. No CIRCL, MalwareBazaar, or YARAify corroboration was present, making the lone detection most consistent with a false positive.
What We Detected
Kingsoft was the only engine among 74 to flag the archive, using the generic label “malware.kb.a.750.” No tier-1 engine detected it, and there was no shared malware-family identification. The archive has been observed for 1244 days across 159 sources and 173 submissions.
Threat Behavior
One sandbox run recorded T1562.001 and connections to 13.107.6.158 and 23.209.116.41, but it did not produce a malicious sandbox conclusion. Because contactedHosts is unavailable, those IP addresses do not have a complete saved reputation cross-check. Ten children were inspected without a malicious child finding, although their individual verdicts remain unknown. Researcher intelligence supplied no CIRCL, MalwareBazaar, or YARAify hit.
What To Do Now
Prefer an authorized or otherwise reputable distribution source and scan the extracted executable before launching it. Keep endpoint protection enabled, especially because repackaged game archives can be modified independently of the original software.
Where this verdict could be wrong3 caveats
- behaviour.offensiveTechniques includes T1562.001, an impairment-of-defenses technique that warrants caution despite the absence of a malicious sandbox conclusion.
- MalwareTips.Synth.DirectIpC2 fired after contacts to 13.107.6.158 and 23.209.116.41; contactedHosts=null means no complete host-reputation result is available.
- The 10 dropped children have unknown individual verdicts, so droppedChildren.hasMaliciousChild=false does not establish that every extracted component is benign.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- No tier-1 engine detected the archive.
- Only 1/74 engines reported a malicious result.
- The file has 1244 days of history across 159 unique sources.
- behaviour.hasMaliciousSandboxVerdict=false.
- No CIRCL, MalwareBazaar, or YARAify hit was present.
- Kingsoft supplied the sole generic detection among 74 engines.
- T1562.001 appeared in the completed sandbox observation.
- Direct-IP contacts were observed without a complete saved host-reputation cross-check.
- All 10 extracted children have unknown individual verdicts.
Use a reputable source and rescan the extracted executable before running it. Keep antivirus and endpoint protection enabled.

Detection sources at a glance
The available sources did not agree on a named threat category.
MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
Behavioral heuristics matched patterns associated with malware. Corroborating evidence determines how much weight they carry.
The sample contacted an external IP address directly and no application domain was recorded. Direct-IP traffic also occurs in legitimate installers and infrastructure, so this is supporting context only and requires corroboration from host reputation and other runtime evidence.
