While cybercriminals are constantly looking for new ways to compromise IT systems, sometimes the old ways work just fine. Two cybersecurity vendors recently noted malware getting spread through a tried-and-true method: Microsoft Word documents.

In one case, cybercriminals were using interest in Microsoft’s new operating system, Windows 11, to lure victims into downloading a malware-laden Word document, according to research from Anomali Threat Research. The Windows 11-themed documents, distributed in June and July, contained a JavaScript backdoor used to compromise the victim’s PC.
