Securing Business Emails Against Ransomware

Ransomware is a dangerous type of malware designed to block access to a victim’s computer system by encrypting critical files until a hefty sum of money demanded by the attacker is paid. The vast majority of ransomware is distributed via email.

Anatomy of a Ransomware Attack

While modern ransomware attacks range from simple “ransomware in a box” to customized malware designed specifically
to evade detection, attacks generally follow the same four phases:

Phase 1


Cybercriminals can easily purchase ransomware on the Dark Web or quickly launch attacks using hosted ransomware services.

Phase 2


Threat actors launch attack campaigns, often masquerading as a known or trusted individual or organization.

Phase 3


Tricked into thinking that the email is from a trusted partner or colleague, the recipient unsuspectedly opens the malicious attachment it contains. Once opened, the ransomware is activated and payment is demanded.

Phase 4


When activated, the ransomware locks up the victim’s system until payment is made to the attackers in the form of untraceable Bitcoin. In many instances, victims never regain control of their systems - even once the specified ransom is paid.
