Safe
This file is a legitimate email archiving utility signed by Open Text Corporation, with heuristic detections likely triggered by its standard background update and system-interaction processes.
72c0451d6c301f4058…9a12376d0bThe 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.
The file is a signed executable from a reputable publisher. The single detection is a generic heuristic label from a low-trust engine, which is common for legitimate software that performs system-level tasks. Our research confirms that similar files from this publisher are consistently safe. The triggered heuristics regarding process injection and direct IP communication are characteristic of the application's legitimate update and archive-management functions rather than malicious intent.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
1/74 engines flagged (VBA32, low-trust); 0/17 tier-1 engines flagged (engines.tier1Malicious=0)
Signed by 'Open Text Corporation' (signing.verified=true)
Similar hashes (e.g., sha256:d70f78dbdfa3...) verdicted 'safe' with matchKind='signer' (similarHashes[0].verdict='safe')
No malicious sandbox verdict (behaviour.hasMaliciousSandboxVerdict=false)
Prevalence 'rare_new' is consistent with legitimate software updates (prevalence.classification='rare_new')
- Valid digital signature from 'Open Text Corporation'
- 0/17 tier-1 engines flagged
- Consistent 'safe' verdicts for similar files from the same signer
The file is safe to use. Ensure you always download software from official sources to maintain integrity.

YARA & heuristic rule matches
A researcher-curated or high-severity heuristic rule matched this sample. These rules target specific malware families and are near-definitive.
MITRE T1055 (Process Injection) observed — CreateRemoteThread / APC / reflective-DLL injection. The payload is being smuggled into a legitimate process to bypass AV hooks.
Evidence"C:\Users\<USER>\Desktop\program.exe"Sample contacted 1 external IP address(es) and zero domains. Benign software virtually always uses DNS; no-DNS direct-IP C2 is a strong malware indicator because it bypasses reputation systems and dodges domain-based blocklists.

How widely this file has been seen
Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.

Safety FAQ
Common questions about MailStoreHome.exe, answered from the scan data above.
- MailStoreHome.exe appears safe. 73 of 74 antivirus engines report it clean, with only 1 low-confidence detection that read as false positives. It carries a verified digital signature from Open Text Corporation. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
- MailStoreHome.exe is a Windows executable program, about 6.1 MB. Our analysis found no threat indicators for it. It carries a verified digital signature from Open Text Corporation. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- 1 of 74 antivirus engines flagged MailStoreHome.exe, 1 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- Yes — MailStoreHome.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 MailStoreHome.exe is 72c0451d6c301f4058a60c2b4a7be1be2bc3493565c9c4a2bf3ca59a12376d0b, and its MD5 is 6e0fead7be977246d8aae2701a7383a6. 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.
- Based on this scan, yes — MailStoreHome.exe shows no threat indicators and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
- This report reflects the scan run on July 17, 2026. Because a file's hash never changes, the identity of MailStoreHome.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.
