Over half of malware-infected emails had Microsoft Office files attached
Although the numbers of malware-infected emails decreased, the issue remains. In 2019, nearly 47% of emailed malicious files were Microsoft Office Word .doc and .docx files, while over 7% were Excel .xls or .xlxs files.
Cybercriminals use Microsoft Office Word or Google Docs quite often. Attaching an infected Word or Docs file is one of the easiest ways they gain access to sensitive information.
According to an article shared by Wired, sending infected Google Docs files is the future of phishing: it tricks the user into granting permissions to a third-party application that looks like a Google docs file, opening new possibilities of exploiting sensitive data.
Typical phishing schemes take visitors to malicious websites. Meanwhile, visitors giving access to third-party applications allow hackers to get access to their emails or address books.
The second most common type of emailed malware were portable executable format files. In 2019, over 28% of malware-infected files sent over email were in the .exe format.
At the same time, more than 8% of malicious files sent through email were in .HTML format. Typically, malicious HTML files direct to breached web pages or phishing sites. By entering the latter, visitors get their credentials stolen.
