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 |
| CRYPTOCOMPANY OÜ | DigiCert EV Code Signing CA (SHA2) | Self Signed |
Block Information
Block Information
During analysis, EnigmaSoft breaks file samples into logical blocks for classification and comparison with other samples. Blocks can be used to generate malware detection rules and to group file samples into families based on shared source code, functionality and other distinguishing attributes and characteristics. This section lists a summary of this block data, as well as its classification by EnigmaSoft. A visual representation of the block data is also displayed, where available.| Total Blocks: | 22,237 |
|---|---|
| Potentially Malicious Blocks: | 167 |
| Whitelisted Blocks: | 13,279 |
| Unknown Blocks: | 8,791 |
