A new attack technique known as ‘HTML smuggling’ spreads malware via email and is increasingly targeting all organizations.
What Is HTML Smuggling and How Does It Work?
Staying Safe From HTML Smuggling Attacks
To successfully defend against HTML smuggling, a layered security approach is required. Microsoft advises stopping the attack chain before it starts. Begin by contacting an IT provider who can assist you in remaining secure.
JENLOR recommends the following measures to protect against HTML smuggling and other attacks that are likely to slip through perimeter defenses:
- Limit an attacker’s ability to move laterally by segmenting networks.
- Utilize services such as Microsoft Windows Attack Surface Reduction, which protects machines at the operating system level from malicious scripts and the spawning of invisible child processes.
- Ensure that firewall rules are configured to block traffic from known malicious domains and IP addresses.
JENLOR can help organizations concerned about HTML smuggling by providing security awareness training as well as email security with targeted threat protection, attachment protection, and URL protection.
