This method exploits vulnerabilities in an operating system’s clipboard feature to steal copied data. If sensitive information is copied, attackers can access that data without the victim’s knowledge. - 🎣 Credential Harvesting
Credential harvesting is the process of collecting user login information through deceptive tactics, often involving phishing emails or fake websites. This method aims to capture sensitive data for unauthorized access. - 📧 Business Email Compromise (BEC)
In BEC scams, attackers pose as trusted partners, such as vendors or high-level executives, to manipulate employees into transferring money or sensitive information. These attacks often rely on social engineering tactics and thorough research on the targeted company. - 🐳 Impersonation of Executives (Whaling)
Whaling is a highly targeted form of phishing aimed at high-profile individuals, such as company executives. Attackers impersonate these executives to solicit sensitive information or funds, often exploiting the authority associated with their positions. - 📧 Email Account Compromise (EAC)
This sophisticated attack occurs when cybercriminals gain unauthorized access to legitimate email accounts, using techniques like password spraying or phishing. Once inside, attackers can impersonate the victim, manipulate email communications, and potentially access sensitive information. - 📱 Addquishing
This tactic combines address book hijacking and phishing. Attackers compromise a victim’s address book to send phishing messages to their contacts, effectively using the victim’s trust against them to spread the attack. - 📧 Spim
Spim refers to spam messages sent over instant messaging platforms. Just like email spam, it can contain malicious links or requests for personal information, often leveraging social engineering to manipulate recipients. - 🔗 Quishing
Quishing attacks utilize QR codes that direct victims to malicious websites, often leading to data theft or malware downloads. As QR codes become more popular, this method can catch victims off guard by seeming legitimate.
II. Social Media and Communication-based Attacks
- 💼 Reverse Social Engineering
In this scheme, attackers create a situation that causes the victim to seek help from them, thereby voluntarily providing sensitive information. This tactic turns the victim’s need for assistance into a vulnerability for exploitation. - 🧠 Psychological Manipulation
Attackers exploit psychological triggers and cognitive biases to influence their victims’ decisions. By appealing to emotions such as fear, urgency, or greed, attackers can manipulate behavior to gain sensitive information. - 👤 Pretexting
This involves crafting a false narrative or scenario to convince victims to divulge information. Attackers fabricate identities or situations, making it easier for them to extract personal or confidential information. - 🎰 Quid Pro Quo
In quid pro quo attacks, the attacker offers a service or benefit in exchange for sensitive information or access. This reciprocal arrangement can manipulate victims into divulging confidential information. - 🥷 Hoax Calls
Making fake emergency or crisis calls, attackers manipulate individuals or organizations into disclosing sensitive information or taking specific actions under duress, often invoking fear or urgency. - 📞 TOAD (Telephone Oriented Attack Delivery)
TOAD is a refined vishing technique utilizing automated systems to conduct large volumes of calls. This method, often employing social engineering tactics, aims to trick victims during the phone call.
