MT AI Engine · Verdict analysis

The reasoning behind this verdict

The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.

65%Confidence
High
Reasoning

Zero malicious detections and a verified Open Text signature provide strong benign signals. Five similar hashes sharing the same signer were previously classified safe under ai:benign_signed_installer. The counter-evidence is the rare_new prevalence classification, absence of signer history, and the MalwareTips.Synth.ProcessInjection heuristic citing T1055. Sandbox execution produced no malicious verdict and no malicious children or hosts were observed.

Key signals · 5

Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

  1. engines: 0 malicious detections across 69 reporting engines

  2. signing.verified=true, signer='Open Text Corporation'

  3. similarHashes: 5/5 prior verdicts 'safe' (matchKind=signer)

  4. triggeredHeuristics: MalwareTips.Synth.ProcessInjection (T1055) fired

  5. prevalence.classification=rare_new, signerStats.found=false

Points in its favour
  • 0/73 engines malicious
  • verified signature from Open Text Corporation
  • 5 similar hashes previously safe (signer match)
Points against
  • rare_new prevalence (1 submission)
  • no prior signer history
  • T1055 process-injection heuristic triggered
Recommended action

Treat as untrusted until more samples or official Open Text confirmation appears; isolate execution or request additional analysis.

What this file does

What it attempted when executed in an isolated sandbox

  • High concern: Hides inside another running program to evade antivirus.

  • High concern: Talks to a remote server to take commands or send out your data.

  • High concern: Downloads more malware onto your PC.

  • High concern: Tries to disable or bypass your security software.

  • High concern: Hijacks how Windows loads programs so it runs automatically.

  • Moderate concern: Obfuscates or packs its code to avoid detection.

  • Moderate concern: Runs hidden system commands (script or shell).

Translated from the file's technical behaviour during analysis. It never ran on your device.

What to do now

We couldn't fully clear this file. Treat it with caution.

  1. Don't run it unless you're certain it came from a source you trust.

  2. Check where you got it — an email attachment or a random download link is a red flag.

  3. If you're unsure, delete it. You can always re-download a clean copy from the official source.

  4. If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

Safety FAQ

Common questions about MailStorePDFEmbeddedFilesExtractor.exe, answered from the scan data above.

  • MailStorePDFEmbeddedFilesExtractor.exe is suspicious — treat it as unsafe until you're sure. 0 of 73 antivirus engines flag it, which isn't a strong consensus but is enough to be cautious. Don't run it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
  • MailStorePDFEmbeddedFilesExtractor.exe is a Windows executable program, about 20 KB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
  • None — all 73 antivirus engines we queried report MailStorePDFEmbeddedFilesExtractor.exe as clean. That's reassuring, though brand-new malware can briefly evade detection before vendors add signatures, so we also weigh the file's behaviour and reputation.
  • 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.
  • To remove MailStorePDFEmbeddedFilesExtractor.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 the original MailStorePDFEmbeddedFilesExtractor.exe file and empty the Recycle Bin/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.
  • Yes — MailStorePDFEmbeddedFilesExtractor.exe carries a valid digital signature from Open Text Corporation, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
  • The SHA-256 hash of MailStorePDFEmbeddedFilesExtractor.exe is 6314facf6aca4c4e1dc4c4004b4195d353232863468db0bbd33f2dfa15d5de5a, and its MD5 is aeafc3eb17b9230f15809a72dca65e3d. 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.
  • This report reflects the scan run on July 17, 2026. Because a file's hash never changes, the identity of MailStorePDFEmbeddedFilesExtractor.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.

Files are processed in a streaming pass-through — MalwareTips never stores the binary on its servers. Only the scan result (hash, detections, verdict) is retained so the next person who scans the same file gets an instant answer. If you ran this file on your computer and are worried, scan your system with an up-to-date antivirus and change critical passwords from a different device.
