“The research focused on five obfuscation techniques that were explained in our previous blog,” Akamai says. “There was a significant increase in four of the monitored techniques between November 2019, and August 2020. The techniques that increased the most during the recorded period are content escaping obfuscation techniques (72%), Base64 encoding (800%), hex encoding variable name obfuscation (86%), and eval execution obfuscation (400%).”
The researchers note that this activity began rising dramatically around the beginning of May 2020, which Akamai believes was due to an increase in phishing activity due to the pandemic.
Most of the impersonated brands were in three sectors: high technology (29.2%), financial (21.4%), and social media (20.6%). Phishing scams impersonating media, e-commerce, and dating companies were also common.
Akamai believes these techniques will grow more common as attackers try to stay ahead of the security industry.
New-school security awareness training can enable your employees to thwart the phishing attacks that don’t get blocked by technical solutions.
