Once used exclusively by the cybercriminals behind REVil ransomware and the Gootkit banking trojan, GootLoader and its primary payload have evolved into an initial access as a service platform—with Gootkit providing information stealing capabilities as well as the capability to deploy post-exploitation tools and ransomware.
GootLoader is known for using search engine optimization (SEO) poisoning for its initial access. Victims are often enticed into clicking on malicious adware or links disguised as legitimate marketing, or in this case a legitimate Google search directing the user to a compromised website hosting a malicious payload masquerading as the desired file. If the malware remains undetected on the victim’s machine, it makes way for a second-stage payload known as GootKit, which is a highly evasive info stealer and remote access Trojan (RAT) used to establish a persistent foothold in the victim’s network environment.
