Angler emerged in 2013 and now is one of the most famous and sophisticated exploit kits in the cyber criminal community. It features aggressive tactics to avoid being detected by security products and can exploit a vast array of software vulnerabilities to infect unsuspecting victims with malware. Because it’s usually spread through drive-by downloads, Angler is extremely difficult to detect and can infect users without any interaction. It also features fileless infection capabilities and it’s able to deliver a variety of payloads, from ransomware, to Trojans, rootkits and backdoor Trojans. Its prevalence is also consolidated by the fact that cyber criminals don’t need advanced technical skills to use it and the fact that it’s a constantly evolving threat.
