Menlo Security Finds Cloud Migration and Remote Work Gives Rise to New Era of Malware, Highly Evasive Adaptive Threats (HEAT)

February 2, 2022Menlo Security, a leader in cloud security, today announced it has identified a surgeincyberthreats, termed Highly Evasive Adaptive Threats (HEAT) thatbypasstraditional security defenses.HEAT attacks are a class of cyber threats targeting web browsers as the attack vector and employs techniques to evade detection by multiple layers in current security stacks including firewalls, Secure Web Gateways, sandbox analysis, URL Reputation, and phishing detection. HEAT attacks are used to deliver malware or to compromise credentials, which in many cases leads to ransomware attacks.

In an analysis of almost 500,000 malicious domains, The Menlo Security Labs research team discovered that 69% of these websites used HEAT tactics to deliver malware.These attacks allow bad actors to deliver malicious content to the endpoint by adapting to the targeted environment. Since July 2021, Menlo Security has seen a 224% increase in HEAT attacks.

“With the abrupt move to remote working in 2020, every organization had to pivot to a work from anywhere model and accelerate their migration to cloud-based applications. An industry report found that 75% of the working day is spent in a web browser, which has quickly become the primary attack surface for threat actors, ransomware and other attacks. The industry has seen an explosion in the number and sophistication of these highly evasive attacks and most businesses are unprepared and lack the resources to prevent them,” said Amir Ben-Efraim, co-founder and CEO of Menlo Security. “Cyber Threats are a mainstream problem and a boardroom issue that should be on everyone’s agenda. The threat landscape is constantly evolving, ransomware is more persistent than ever before, and HEAT attacks have rendered traditional security solutions ineffective.”

HEATattacksleverage one or more of the following core techniques that bypass legacy network security defenses:

“Highly Evasive Adaptive Threat (HEAT) attacks evade existing security defenses by understanding all the technology integrated into the existing security stack and building delivery mechanisms to evade detection,” said John Grady, ESG Senior Analyst. “Organizations should focus on three key tenets to limit their susceptibility to these types of attacks: shifting from a detection to a prevention mindset, stopping threats before they hit the endpoint, and incorporating advanced anti-phishing and isolation capabilities.”
