Booster scripts are add-on scripts for
High Orbit Ion Cannon (HOIC), a denial-of-service (DoS) tool used widely by the hacktivist group Anonymous. Booster scripts come in the form of .hoic text files, allowing HOIC users to implement some anti-DDoS randomization counter measures as well as increase the magnitude of his or her attack. While HOIC - similarly to
Low Orbit Ion Cannon (LOIC) - still has no significant obfuscation or anonymization techniques to protect the user, the use of .hoic booster scripts allows a user to specify a list of rotating target URLs, referrers, user agents, and headers in order to more effectively cause a
DoS condition by attacking multiple pages on the same site, as well as make it seem like attacks are coming from a number of different users.
