HEAT attacks: A new spin on browser exploit techniques
It is no secret that the web browser is becoming an increasingly popular target for cybercriminals looking to compromise an endpoint to gain entry to a network. The increased business use of the browser (remote work) on networks that lack the perimeter security infrastructure of traditional campus networks has made them easier to exploit. In recent months, we have seen an increase in cyberattacks and data leaks caused by browser-related security incidents, including a data breach caused by a phishing attack on Dropbox that gained the hacker access to over 100 of the company’s code repositories in November, and December’s CircleCi breach resulting from an infection of information-stealing malware.
Highly Evasive Adaptive Threats, or HEAT attacks, are a new spin on existing browser exploit techniques that make them much more dangerous. These attacks exploit browsers by leveraging features and tools to bypass traditional security controls and then attack from within, including compromising credentials or deploying ransomware. Comprised of known tactics such as phishing messages, HTML smuggling and dynamic drive-by downloads, these attacks frequently target SaaS applications and other web-based tools that are critical to productivity.
