Final Answer:
The type of cybercrime on social media that spreads attacks by posting updates on the victim's newsfeed is commonly known as "Social Engineering" or more specifically, "Social Media Impersonation."
Step-by-step explanation:
Social Engineering involves manipulating individuals into divulging confidential information or taking specific actions. In the context of spreading attacks on social media, perpetrators often use deceptive tactics to gain access to an individual's account and post malicious content on their newsfeed. This can include phishing schemes where users unknowingly share sensitive information, enabling attackers to compromise their accounts. Social Media Impersonation, a subset of social engineering, involves attackers posing as the victim to spread false or harmful information. By exploiting trust within the social network, these cybercriminals aim to amplify the impact of their attacks.
In the realm of cybersecurity, understanding the mechanisms behind social engineering is crucial. Perpetrators employ psychological techniques to exploit human vulnerabilities, making individuals more susceptible to falling victim to these attacks. Through careful observation of online behavior and the creation of convincing phishing messages, attackers gain unauthorized access to accounts, allowing them to manipulate victims' newsfeeds. As social media platforms continue to play a significant role in communication, education about these tactics and the promotion of secure online practices are essential for mitigating the risks associated with social engineering attacks. Vigilance and education are key components in the ongoing effort to protect individuals from falling prey to such cybercrimes.
