The increased use of Counterfeit Digital Certificates in Malware

The previous trend of using stolen certificates to digitally sign malware (to circumvent OS’s requirements for valid digital signatures om files to install SW) has been overtaken by black hats issuing counterfeit certificates pretending to be the institution the certificates are issued to. Social engineering to the next leve is one way of looking at this. Recorded Future has an analysis of the current market place, with a tracking of the 3 largest dark web merchants and their volumes over the last 5 years. Also a breakdown of the current offerings available. Note that the high-end  certs are Symantec Certs, the CA that got phased ut by the browser vendors after numerous issues, so the hope is that this will remove the EV certificates from this kind of use.
