HP Wolf Security has announced the discovery of a new epidemic of malware infection using PDF files.
According to experts, the attackers send an e-mail with a notification of payment and an attached PDF document. Once opened, Adobe Reader prompts you to run the DOCX document contained in the file, which will trigger the virus. In addition, it became known that hackers also learned to cheat security systems and present the file as verified.
This scheme uses vulnerability CVE-2017-11882, which was closed in November 2017, but it still occurs on the computers of some users who do not care about security.
According to a report by HP Wolf Security, in the first quarter of this year, more than 45% of stopped attacks on computers used Microsoft Office formats in one way or another.
