This means the the hackers behind the Sony Pictures hack attacks are now leaking digitally signed Sony Pictures certificates to cyber criminals. This may be done for a price according to report.
As per the image above, the certificate which has been obtained by Kaspersky has been signed on December 5, 2014 and the Sony hack attack occurred in last week of November, 2014 which means that there may be more malware which come signed with certificates of Sony Pictures in near future. The old certificate which previously observed is a non signed form, as MD5: 6467c6df4ba4526c7f7a7bc950bd47eb and appears to have been compiled in July 2014.
The Sony hack attack is so massive that it has leaked unreleased Sony movies, the salary, ssn and other personal details of Sony employees and Hollywood celebrities and now the presence of digital certificate in a malware points to the fact that the aftershocks of the #GOP hack may be far from over.
