Phishing attacks are evolving faster than ever, and cybercriminals are now leveraging SVG (Scalable Vector Graphics) attachments to slip past email filters. This new technique isn’t just clever—it’s dangerous. Here’s what you need to know to protect your organisation from falling victim.
Why SVG Attachments Are the New Phishing Frontier
SVG files are commonly used for graphics and icons due to their scalability and lightweight design. However, they also have a lesser-known capability: they can embed JavaScript and other interactive elements. Cybercriminals exploit this by using SVG attachments in phishing emails to execute malicious scripts when the file is opened.
This tactic has several advantages for attackers:
- Bypassing Email Filters: Traditional security tools may not flag SVG files because they are often used for legitimate purposes.
- Embedding Malicious Code: Attackers can include scripts that download malware or redirect users to fake websites designed to steal credentials.
- Deceptive Appearance: Since SVGs are image files, they can appear harmless to unsuspecting recipients.
How These Phishing Attacks Work
A typical phishing email using an SVG attachment might:
- Include a “harmless-looking” file: The email could claim to be a receipt, invoice, or other routine document.
- Redirect to a malicious website: When the SVG is opened, embedded JavaScript could redirect the user to a phishing site disguised as a legitimate login page.
- Steal credentials or deploy malware: The victim unknowingly provides sensitive information or downloads a malicious payload.
What This Means for Your Business
SVG phishing attacks highlight a broader problem: attackers are constantly finding ways to exploit common file types. Without robust security measures, organisations risk exposing sensitive data, falling victim to ransomware, or suffering reputational damage.
How to Protect Your Organisation
Here are steps you can take to defend against this emerging threat:
