TLAPIA - 1.8% Detection Rate *
Did you just find a download or a file on your computer that has a digital signature from TLAPIA? If so, please read on.
You will typically notice TLAPIA when clicking to run the file. The publisher name is then displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:
You can also view the TLAPIA certificate with the following steps:
- Open up Windows Explorer and locate the TLAPIA file
- Right-click the file and select Properties
- Click on the Digital Signatures tab
- Click on the View Certificate button
Here is a screenshot of a file that has been digitally signed by TLAPIA:
As you can see in the screenshot above, Windows states that "This digital signature is OK". This implies that the file has been published by TLAPIA and that the file has not been tampered with.
If you click the View Certificate button shown in the screengrab above, you can examine all the details of the certificate, such as when it was issued, who issued the certificate, how long it is valid, etc. You can also see the address for TLAPIA, such as the street name, city and country.
VeriSign Class 3 Code Signing 2010 CA has issued the TLAPIA certificates. You can also examine the details of the issuer by clicking the View Certificate button shown in the screenshot above.
