Spear phishing is a highly targeted cyberattack in which criminals research a victim and send convincing phishing emails. More specifically, it is a targeted email attack aimed at a specific individual or organization where attackers use personal or organizational details to craft convincing messages that trick recipients into revealing sensitive information, transferring funds, or downloading and installing malware.
The difference between spear phishing and conventional phishing is that spear phishing is designed for a specific target, whereas conventional phishing campaigns look to cast a wide net.
How Spear Phishing Works
Spear phishing is highly detailed and requires extensive research to successfully impersonate a known individual and win the target's trust. Spear phishers can research their victims on social media, company websites, and the dark web before sending a convincing message.
Primary Goals
The primary goals of spear phishing are financial theft and data exfiltration.
Spear phishing attacks are particularly dangerous because they are highly personalized and difficult to detect with traditional security tools. The attacker may reference specific projects, colleagues, or recent events to make the email appear legitimate.
How to Stop Spear Phishing
Organizations can defend against spear phishing by deploying advanced email security solutions that use AI to analyze the content, context, and behavioral signals of every email. Employee security awareness training is also critical, as is implementing multi-factor authentication to limit the damage if credentials are compromised. Pangratis detects spear phishing attacks by analyzing the precise signals that indicate targeted impersonation, even when the email passes authentication checks and contains no known malicious links or attachments.
