Securing Business Emails Against Spear Phishing

Spear phishing is a highly targeted form of email phishing in which an attacker impersonates a trusted sender to trick victims into sharing sensitive credentials or downloading ransomware on corporate systems.

What Is Securing Business Emails Against Spear Phishing?

Spear phishing is becoming an increasingly popular attack vector because it is generally more successful than conventional phishing. As opposed to sending hundreds of thousands of relatively generic emails out at a time, spear phishing campaigns involve researching victims and using advanced intelligence strategies to compose just a select few highly convincing messages.

Anatomy of a Securing Business Emails Against Spear Phishing Attack

The majority of spear phishing attacks follow the same four phases:

Phase 1


Select Targets

Cyberthieves collect data available on the Internet from data breach, social media profiles and corporate websites to build their target list.

Phase 2


Build Attack

Prior to launching the attack campaign, cybercriminals develop their payloads such as building phony websites impersonating legitimate organizations or brands to deceive their victims.

Phase 3


Launch Campaign

Cybercriminals launch spear phishing campaigns targeting the victims they’ve identified in their target list. Emails sent in these campaigns do not necessarily rely on malicious links or attachments to deceive recipients. Instead, attackers use stealthy impersonation tactics such as spoofing, look-alike domains, or display name deception.

Phase 4


Reap Rewards

Once the victim takes the action requested in the email, such as clicking a phishing link or opening a malicious attachment, attackers are able to login to the victim’s account or access their system to steal confidential information that can be monetized for personal gain.
