Is OnlyOfficePortable_9.2.0_online.paf.exe safe?
Unsigned portable installer with one low-trust detection and direct-IP traffic but no tier-1 consensus.
One low-trust engine flagged the file; 73 others did not. The sample is unsigned and shows direct-IP connections, yet no tier-1 engine or sandbox verdict supports malice.

Before running
Do not run it until the source and publisher can be verified independently.
If you already ran it
Stop using it, scan the device, and watch for unexpected behavior or security alerts. Get a fresh copy from the developer's official site or an official app store.
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.
One low-trust engine flagged the file; 73 others did not. The sample is unsigned and shows direct-IP connections, yet no tier-1 engine or sandbox verdict supports malice.
The single malicious label comes from a low-trust engine, leaving tier1Malicious at zero. The file is unsigned, which is common for portable packages but removes the safety net of a trusted signer. Similar imphash matches are mostly suspicious rather than malicious, suggesting installer-framework noise. Direct-IP traffic triggered a heuristic, yet sandbox results and dropped children remain clean. Medium prevalence and portable filename further reduce the likelihood of a targeted threat.
What We Detected
74 engines scanned the file; only APEX returned a malicious result. No tier-1 engine agreed. The binary is unsigned and contains no code-signing certificate.
Threat Behavior
Sandbox execution extracted two ZIP archives and wrote legitimate OnlyOffice binaries. Two MITRE techniques (T1134, T1486) were observed, but no malicious sandbox verdict or malicious child file was produced. Six direct IP addresses were contacted without domain names.
What To Do Now
Keep Windows Defender and other endpoint protection enabled. If the file originated from the official OnlyOffice portable project, compare its SHA-256 against their published checksums before execution.
Where this verdict could be wrong1 caveat
- similarHashes[1-4] returned suspicious verdicts on same imphash, indicating installer-framework noise rather than consistent malicious family.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 70 of 74 engines returned clean
- medium prevalence across 63 sources
- no malicious dropped children
- unsigned executable
- direct-IP network traffic
- one low-trust malicious label
Treat as unverified; verify the SHA-256 against the vendor before running or obtain a signed build from the official site.

What this file does
Observed actions and their security significance
High concern: Encrypted files or data, behaviour commonly associated with ransomware.
High concern: Changed an auto-start location that can make code run after sign-in or restart.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
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: Scans through your files and folders.
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.

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.
