Is iThmbConv.exe safe? Yes, no threats found.

What We Detected

This is a small Windows executable (about 105 KB) first seen on Feb 7, 2011. None of the 72 antivirus engines that checked it flagged it, and the 18 highest-trust engines all returned a clean verdict. The file is not compressed or packed, its code section sits at normal entropy, and nothing in its structure suggests obfuscation.

Two community detection patterns matched during reputation lookups. One is explicitly a demonstration rule and the other targets macro documents, which this executable is not. No engine on either of our top two trust tiers picks the file up, and the analysis runs found nothing to corroborate them, so they read as coincidental pattern matches rather than evidence of a real threat.

Threat Behavior

Five sandbox runs were completed and the combined result was clean. The runs recorded no injection into other processes, no persistence through the registry or startup locations, no program markers and no credential or defence-tampering artefacts. The behaviour that was logged — reading system information, ordinary network calls and library loading — is the same set of techniques seen in everyday software.

Network activity was limited to analysis-machine background traffic: the domains and addresses observed during the runs are the analysis environment's own contacts, not the program's. We checked eleven hosts against our reputation data and none were known to be harmful.

What To Do Now

No action is needed for this file. Because it is an old, unsigned program, keep security software switched on when you run it and download it only from the place you originally obtained it, so you know exactly which copy you are using.
