HijackLoader is a modular malware acting as a vehicle for distributing different types of malicious software on compromised systems. It gained prominence during the summer of 2023 and has since been used in multiple attacks against organizations from various sectors, including hospitality businesses.

A loader is malicious software that infiltrates devices to deliver malicious payloads. This malware is capable of infecting victims’ computers, analyzing their system information, and installing other types of threats, such as trojans or stealers. Criminals usually deliver loaders through phishing emails and links by relying on social engineering to trick users into downloading and running their executables. Loaders employ advanced evasion and persistence tactics to avoid detection.
