Evasion at its core:
Understanding the malicious power of HTML smuggling
HTML smuggling allows attackers to encode a malicious script within a specially crafted HTML attachment or web page. When the target user opens the HTML in their web browser, the browser decodes the malicious script, assembling the payload on the host device. Unlike traditional malware delivery methods, HTML smuggling ensures that the malicious executable is built locally behind a firewall, evading network-based security measures.
Without comprehensive security solutions in place, organizations may find themselves manually searching for indicators of HTML smuggling and other sophisticated threats. Security Operation Center (SOC) analysts equipped with sufficient information about specific threats can conduct manual investigations, but relying solely on manual efforts can be time-consuming and resource-intensive.
To effectively combat the risks associated with HTML smuggling and other advanced attack techniques, organizations should prioritize the implementation of advanced security solutions that provide holistic protection across multiple layers of the IT infrastructure. By adopting a proactive approach and investing in robust security measures, organizations can safeguard their systems, data, and operations against the evolving threat landscape.
