Explanation
Account hijacking is a malicious activity primarily aimed at gaining unauthorized access to a user’s online accounts, such as email, social media, or financial accounts, for a variety of nefarious purposes. The perpetrators, commonly known as hackers or cybercriminals, use a range of techniques such as phishing, social engineering, and exploiting weak passwords to compromise users’ account security.
Once a user’s account is commandeered, the hacker can then utilize it for various malicious activities such as identity theft, financial fraud, spreading disinformation, or even launching attacks on other systems, thereby extending the reach of their malicious campaign. One of the primary purposes of account hijacking is to exploit the sensitive data held within these accounts for personal or financial gains.
This could include anything from stealing financial information for making fraudulent transactions to accessing and leaking personal or business data for extortion. A hijacked account can also be weaponized by an attacker to spread disinformation or harm the reputation of the user, through sharing inappropriate messages or content.
To combat the threat of account hijacking, it is vital for individuals and organizations to maintain robust cybersecurity practices such as using strong, unique passwords, enabling multi-factor authentication, and keeping systems updated with the latest security patches.
Examples of Account Hijacking
Twitter Hack 2020: In July 2020, several high-profile Twitter accounts, including those of celebrities and prominent political figures such as Barack Obama, Joe Biden, Elon Musk, and Bill Gates, were compromised.

The attackers gained access to email addresses, passwords, phone numbers, and other confidential user data which were later sold on the dark web. The widespread account hijacking is considered one of the largest data breaches in history. Yahoo faced severe criticism for its lack of security measures and slow response, as well as financial losses related to the incidents, leading to the company’s acquisition by Verizon Communications in
iCloud Celebrities Hack 2014: In August 2014, a large-scale account hijacking event, dubbed “The Fappening” or “Celebgate”, took place, affecting many celebrities, including Jennifer Lawrence, Kate Upton, and Kirsten Dunst.
