Types of spear phishing
Spear phishing manifests in various forms, each exploiting different avenues to achieve malicious objectives. Understanding these distinct types of spear phishing is crucial for individuals and organizations seeking to fortify their defencesdefenses against evolving cyber threats. Let’s explore some common types:
- Business Email Compromise (BEC):
Objective: BEC attacks involve compromising business email accounts to conduct fraudulent activities.
Tactics: Attackers often impersonate executives or employees, manipulating trust to request unauthorized fund transfers, sensitive information, or changes to financial processes.
- Whaling Attacks:
Target: Whaling attacks focus on high-profile individuals within an organization, such as executives or CEOs.
Exploitation: By exploiting the authority and access these individuals possess, cybercriminals aim to gain privileged information or execute actions detrimental to the organization.
- Malicious Links and Attachments:
Delivery Mechanism: Spear phishing often involves the delivery of malware through malicious links or attachments.
Deception: Cybercriminals create compelling narratives, enticing targets to click on links or download attachments that, once opened, install malware on the victim’s system.
- Credential Harvesting Attacks:
Objective: Attackers aim to harvest login credentials by tricking individuals into providing usernames and passwords.
Impersonation: The attackers may pose as trusted entities, such as IT support or colleagues, urging the target to disclose sensitive authentication information.
- CEO Fraud Attacks:
Impersonation: In CEO fraud attacks, cybercriminals impersonate high-ranking executives to manipulate employees.
Instructions: The attackers issue instructions to employees, often related to financial transactions or confidential information sharing.
