Description: Account hijacking is a form of identity theft where an attacker takes control of a user’s account, whether on social media, email, or online service platforms. This type of attack is carried out through various techniques, such as phishing, where the attacker deceives the victim into revealing their credentials, or through the use of malware that captures sensitive information. Once the attacker gains access to the account, they can perform malicious actions, such as sending fraudulent messages, stealing personal information, or making unauthorized transactions. The relevance of account hijacking has increased with the growth of digitalization and the use of online services, leading to a greater focus on web application security. The main characteristics of this type of attack include psychological manipulation of the victim, exploitation of vulnerabilities in application security, and the potential to cause significant harm to both individuals and organizations. Preventing account hijacking involves implementing robust security measures, such as two-factor authentication, strong passwords, and educating users about safe online practices.
