An active campaign has been spotted that utilizes HTML smuggling to deliver malware, effectively bypassing various network security solutions, including sandboxes, legacy proxies and firewalls.
Krishnan Subramanian, security researcher with Menlo Security, told Threatpost that the campaign uncovered on Tuesday, dubbed “Duri,” has been ongoing since July.

Learn more about this latest attack and how enterprises can protect themselves from HTML-smuggling attacks, during this week’s Threatpost podcast.
