What is Social Engineering?
Social engineering is a tactic of manipulating, influencing, or deceiving a victim to gain over their computer systems to steal personal and financial information. Social engineering attacks happen in one more step, the perpetrator first investigates the intended victim to gain the necessary background information such as potential points of entry and weak security protocols. Next, the attack uses a form of pretexting such as impersonation to gain a victim’s trust and provide stimuli to break security practices to reveal sensitive information or grant access to critical resources.
Types of Social Engineering Attacks
Phishing
Process of attempting to acquire sensation information such as usernames, passwords, and credit card details by pretending to be a trustworthy entity using bulk email, SMS or phone. Phishing messages create a sense of urgency, curiosity, or fear in the recipients of the message to encourage revealing sensitive information, clicking on links to malicious websites, or opening attachments that contain malware.
Spear Phishing
This is a more targeted version of a phishing scam where an attacker chooses specific individuals or enterprises. The attacker tailor their messages based on characteristics job positions, and contacts belonging to their victims. Spear phishing requires a lot of effort to research its victims and compromise accounts, this often takes weeks and months to pull off. However, they are much harder to detect and have better success rates if done skilfully.
