Malwarebytes uncovers digital certificate-spoofing Trojan

Security vendor Malwarebytes has uncovered a banking Trojan capable of bypassing traditional security by spoofing legitimate digital certificates.

The certificate used by the malware is usually legitimate but it's now being sent out by a fake-company set up to get hold of the certificates from Digicert.

The certificate allows the hacker to sneak a malicious PDF file infected with the Trojan past most computer security systems. Malwarebytes said that the malware had already targeted a slew of high-profile firms. "The malware is a banking/password stealer using email to spread. It appears to be a PDF invoice with a valid certificate issued to a real Brazilian software company which was issued by SSL certificate authority DigiCert," senior security researcher at Malwarebytes Jerome Segura told V3.
