New research warns that more and more emails are arriving with malicious or harmful HTML attachments.
The number of malicious HTML attachments is growing
The Barracuda report found that almost half (46%) of the HTML attachments in the emails they scanned were malicious. Barracuda claims that Hypertext Markup Language (HTML) is increasingly being used in phishing, credential theft and other forms of cyberattacks.
The CTO also states that HTML threats are distributed through an infinite number of individual attacks, rather than a few mass events.
“7. In March, a total of 672,145 malicious HTML artifacts were detected, comprising 181,176 different items. This means that about a quarter (27%) of the detected files were unique, and the rest were duplicated or distributed in bulk. However, on March 23, nearly nine out of ten (85%) of the total 475,938 malicious HTML artifacts were unique, meaning that almost every attack was different,” Shi said.
Data indicates that HTML attachments remain one of the most common ways malware is delivered via email, the blog concluded, adding that it is critical that businesses have appropriate security solutions in place. “This means that it is necessary to have effective, AI-based email protection that can assess the content and context of emails.”
Multi-factor authentication, untrusted access controls, and response automation and attack mitigation are also essential to any organization’s cybersecurity technology stack, along with employee training, Shi concluded.
