File scan report
Verdict Suspicious
Is bdnwrtn. exe safe? Treat it as suspicious.
Unsigned xlsx file with direct-IP network activity and no AV detections but rare-new prevalence.
Why Suspicious? Unsigned file.
Limited evidence · One sign points to a problem; nothing else confirms it.
Exercise caution; the file shows no confirmed malicious behaviour but exhibits an unusual direct-IP network pattern on an unsigned document.
What to do now4 steps
Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.
What to do
Don't run it unless you're sure where it came from.
Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.
If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.
If you already ran it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.
Not sure what to do?
Ask the MalwareTips community before you run it. If you already ran it, follow the cleanup guide.

Why we think so
3 points against it and 2 in its favour, checked against the scan evidence.
The reasoning behind this verdict
The sample is unsigned, only one day old, and triggered a rule for contacting seven external IPs without using DNS. Sandbox analysis found no malicious behaviour and no malicious files it created were dropped.
The file is an Office Open XML spreadsheet that performed routine WMI and system-discovery calls while contacting seven Microsoft-related IPs directly. The triggered one of our behaviour rules flags this pattern as suspicious because legitimate Office documents normally resolve domains. With no signing, no prior history, and rare-new prevalence, the evidence is mixed and does not reach a definitive safe or malicious threshold.
What We Detected
66 of the 65 antivirus engines that checked it scanned the file; none returned a malicious or suspicious label. 17 major antivirus engines explicitly classified it as clean. The sample is an unsigned .xlsx that executed inside Excel and performed seven MITRE techniques common in legitimate software (T1033, T1071, T1082, T1203, T1221, T1497, T1573). It wrote several temporary Office files and created program markers typical of Microsoft Office sessions.
Threat Behavior
The file contacted seven external IP addresses (52.110.7.9, 52.110.7.7, 52.110.7.37, 52.123.250.168, 162.159.36.2, 150.171.109.77, 52.182.141.63) without any domain resolution. One rule flagged this direct-IP pattern. No malicious sandbox verdicts, no malicious files it created, and no external-intel hits were recorded.
What To Do Now
Do not open the file on production systems. If the document was received unsolicited, treat it as potentially risky. Re-scan after more submissions accumulate or request a deeper sandbox trace with network emulation enabled.
Where this verdict could be wrong1 caveat
- Direct-IP contacts (52.110.7.9, 52.110.7.7, etc.) without DNS resolution is unusual for benign Office documents and could indicate a control server, but sandbox returned 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.
- No malicious sandbox verdict
- No malicious files it created
- Unsigned file
- rare and prevalence (0 days old)
- Direct-IP contacts without DNS (7 IPs)
