Digital Signatures
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When analyzing and verifying digital signatures, it is important to confirm that the signature’s root authority is a well-known and trustworthy entity and that the status of the signature is good. Malware is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a malware author with no verification). Malware may also be signed by legitimate signatures that have an invalid status, and by signatures from questionable root authorities with fake or misleading “Signer” names.| Signer | Root | Status |
|---|---|---|
| CRYPTOCOMPANY OÜ | DigiCert EV Code Signing CA (SHA2) | Hash Mismatch |
| CRYPTOCOMPANY OÜ | DigiCert EV Code Signing CA (SHA2) | Self Signed |
