Hacktivism refers to the use of computer hacking skills, cyber techniques, and digital tools to promote, advance, or protest a social, political, or environmental issue. Hacktivists, or individuals who engage in hacktivism, often employ tactics such as website defacement, distributed denial-of-service (DDoS) attacks, data breaches, or the release of sensitive or confidential information to make a statement or raise awareness about a cause. Anonymous, a group of hacktivist, employs coordinated cyberattacks against various world governments, corporations or other groups, often in the name of social or political causes. On February 25, 2022, Anonymous declared that they had launched 'cyber operations' against the Russian Federation, in retaliation for the invasion of Ukraine ordered by Russian president Vladimir Putin. Since then, the group has claimed responsibility for various cyberattacks that disabled websites and leaked data from Russian government agencies.
