Increase in phishing attacks with SVG files detected
Since January 2025, the Sophos X-Ops security team has seen a significant increase in malware and phishing attacks distributed via SVG graphic files.
Cyber criminals use the SVG format to circumvent protection mechanisms and infiltrate malicious code into computer systems unnoticed. SVG files, which are widely used as scalable vector graphics, contain XML code in addition to image information. This feature enables attackers to embed malicious code directly into the files, which is executed in the background when opened. This allows traditional detection mechanisms to be bypassed. The security experts at Sophos X-Ops have been monitoring this attack strategy more closely since 2024.
"We know that cyber criminals use the SVG file format for their attacks, and we have adapted our protection solutions accordingly. What is particularly problematic is that the user receives no visible indication of a threat, as the attacks take place in the background. That's why detection methods, especially AI-based technologies, need to be increasingly trained to identify unusual activity," explains Michael Veit, cybersecurity expert at Sophos.
Increasingly sophisticated attacks
According to Sophos X-Ops, attack methods are constantly evolving. In addition to technically improved attack techniques, targeted localized phishing pages have also been discovered that are designed in the victims' respective national language. This increases the credibility of the attacks and makes them more difficult to detect.
