Oasis Ticket Sales Scams: How to Stay Safe
During our weekly meetings with the banking industry and Police Scotland, we continue to see a significant increase in ticket scams over the last three…
Scalable Vector Graphics (SVG) files are a popular format for web graphics because they can be resized without losing quality. However, cybercriminals are now exploiting SVGs to deliver malware, posing a new threat to unsuspecting users.
Traditionally, SVG files would download malicious content from external sources. This made detection easier, as security software could identify and block these external connections. However, attackers are now finding ways to embed malicious code directly within the SVG file itself. A tool called AutoSmuggle has even been developed to streamline this process for criminals.
There are two main categories of SVG-based attacks:
JavaScript-based attacks: These attacks use JavaScript embedded within the SVG file to download malicious payloads from a remote server.
Archive-based attacks: These attacks involve tricking a user into opening a downloaded archive containing a malicious SVG file.
In both cases, once the SVG file is executed, the malware can steal sensitive information, such as login credentials and credit card details, or take control of the infected device.
The Rise of SVG Malware
Two recent examples highlight the growing danger of SVG malware:
Agent Tesla Keylogger: This keylogger can be hidden within an SVG file and used to capture a user’s keystrokes, including passwords and other sensitive data.
XWorm RAT (Remote Access Trojan): This RAT can also be embedded in SVG files and gives attackers complete control over an infected device.
These are just two examples, and security experts warn that SVG malware is likely to become more prevalent in the future.
