Is exportrsa.exe safe?

Verdict
Malicious

Hacktool for exporting non-exportable RSA private keys, confirmed by YARA rule HKTL_ExportRSA_Feb22_1, process injection (T1055), and evasion tags.

This unsigned executable matches a known hacktool via community YARA rule for ExportRSA, exhibiting process injection and direct IP connections typical of offensive tools. Tier-1 engines like TrendMicro detect it as Trojan.URSU. Despite majority clean detections, behavioral heuristics and anti-analysis tags confirm malicious intent as a hacktool.

Do not run this file

Treat as confirmed hacktool and remove. Monitor for private key tampering or injected processes; full system scan recommended.

Analyst conclusion

This unsigned executable matches a known hacktool via community YARA rule for ExportRSA, exhibiting process injection and direct IP connections typical of offensive tools. Tier-1 engines like TrendMicro detect it as Trojan.URSU. Despite majority clean detections, behavioral heuristics and anti-analysis tags confirm malicious intent as a hacktool.

Where this verdict could be wrong4 caveats
  • tier1ReportedClean=15/17 — majority of high-trust engines undetected.
  • behaviour.hasMaliciousSandboxVerdict=false; no consensus in 1 sandbox.
  • droppedChildren.hasMaliciousChild=false; child SHA256 2a3a3e99... unknown verdict.
  • prevalence.classification=common_old (159 submissions) but reputation=0 may indicate niche tool.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Treat as confirmed hacktool and remove. Monitor for private key tampering or injected processes; full system scan recommended.

What this file does

Observed actions and their security significance

  • High concern: Injected code into another process, a technique that can conceal execution.

  • Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.

  • Moderate concern: Checked the environment for virtualisation or analysis tools.

  • Note: Collects details about your system.

  • Note: Loads extra code modules while running.

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.

Threat context

How hacktools are abused

This is a hacking or cracking tool — the kind used to bypass software licences, generate fake keys, or attack other systems. Even when the tool 'works', these downloads very often carry hidden malware.

Bottom line:Running one means trusting an anonymous author with full access to your PC — rarely worth the risk.

What to do now

This file is dangerous. Treat it as harmful and remove it.

  1. Recovery step 01

    Don't run this file. Delete this file from the device, then empty the Recycle Bin or Trash.

  2. Recovery step 02

    If you already ran it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.

  3. Recovery step 03

    If you typed any passwords while it was open, change them from a device you trust.

  4. Recovery step 04

    Get a fresh copy from the developer's official site or an official app store.

8 evidence-based answers
Is exportrsa.exe malware?
Evidence-based answer
Yes — exportrsa.exe is malicious. Do not run it. Delete this file from the device, then empty the Recycle Bin or Trash. 4 of 76 antivirus engines flag it (family: ExportRSA). It behaves as a hacktool — dual-use offensive tooling that is dangerous regardless of intent. If you've already run it, see the removal and recovery steps below.
What is exportrsa.exe?
Evidence-based answer
exportrsa.exe is a Windows executable program, about 18 KB. Our analysis identifies it as malicious (family: ExportRSA) — a hacktool — dual-use offensive tooling that is dangerous regardless of intent. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
How many antivirus engines detected exportrsa.exe?
Evidence-based answer
4 of 76 antivirus engines flagged exportrsa.exe, 4 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
I already downloaded and ran exportrsa.exe — what should I do?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove exportrsa.exe?
Evidence-based answer
To remove exportrsa.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is exportrsa.exe?
Evidence-based answer
exportrsa.exe is classified as a hacktool — dual-use offensive tooling that is dangerous regardless of intent. Engines attribute it to the ExportRSA family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of exportrsa.exe?
Evidence-based answer
The SHA-256 hash of exportrsa.exe is 99e23a621c888545780f610f418d6dc63f1decc4a0e8838ccf7bcf6aa3b0a97b, and its MD5 is d42f9177a7636f549d19491c4ef2a966. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of exportrsa.exe?
Evidence-based answer
This report reflects the scan run on May 9, 2026. Because a file's hash never changes, the identity of exportrsa.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
