Named ISOMorph, the campaign uses HTML smuggling to drop the first stage malware through the web browser . Attack the browser

The researchers explain that HTML smuggling helps deliver malware by effectively bypassing various network security solutions including sandboxes, legacy proxies, and firewalls .

We believe attackers are using HTML Smuggling to deliver the payload to the endpoint because the browser is one of the weakest links without network solutions blocking it, notes Menlo Security in a blog post analyzing the ISOMorph campaign.

HTML Smuggling was also used in the most recent spear-phishing campaign by
the Nobelium group, the threat actor which perpetrated the SolarWinds supply-chain attack .

Popular with web developers as a means to optimize file downloads , threat actors use HTML smuggling to bypass standard perimeter security, explains Menlo Security.
