Attacks On The Rise

40% of Ransomware Attacks Start as a Phishing Email

Phishing attacks, the leading delivery vehicle for ransomware, are on the rise. Why? Cybercriminals know that they can craft messages that bypass legacy email security solutions and evade detection.
Most legacy phishing tools largely rely on a rule based approach, as well as on a threat intelligence engine, consisting of previously known attack signatures to detect phishing attacks. As a result, organizations learn about these attacks when it’s too late – usually after the compromise has occurred.


Know Your Risks

Detecting Ransomware is Difficult

Detecting and preventing ransomware is extremely difficult because:
  • There can be multiple threat vectors attacking the organization and in several different ways, making the chances of a successful ransomware attack higher,
  • Email is a delivery mechanism of choice for ransomware and phishing attacks have become increasingly sophisticated. CryptoLocker, NotPetya, Locky and TeslaCrypt are some famous examples where phishing was used as a means to deliver a ransomware payload.
  • Legacy, rule-based email security solutions leave organizations unequipped to deal with these advanced threats.
