“EvilProxy” Phishing Tool Puts Microsoft Outlook Users at Risk: How to Protect Your Network
Microsoft Outlook is a widely used email client across the globe. Unfortunately, a new security vulnerability in the desktop client could potentially allow attackers to gain unauthorised access to your network. This vulnerability, known as “EvilProxy,” is a phishing attack that can easily trick users into downloading and executing malicious software.
What is EvilProxy?
EvilProxy is a phishing tool that takes advantage of a critical security flaw in Microsoft Outlook. When a user opens an email that contains a specially crafted attachment, the EvilProxy tool can bypass Outlook’s security features and launch a malware attack on the user’s computer.
The tool exploits a vulnerability in how Outlook handles embedded images in HTML emails. By embedding an image with a specific URL, attackers can access a user’s network without needing any user interaction.
How to Defend Yourself from EvilProxy?
There are several steps you can take to defend yourself against EvilProxy and other phishing attacks:
- Update Your Software: Ensure you have the latest version of Microsoft Outlook installed on your computer. Microsoft regularly releases security updates to address known vulnerabilities.
- Be Wary of Email Attachments: Do not open email attachments from unknown senders. Even if the sender is known, verify the legitimacy of the attachment before opening it.
- Educate Your Staff: Educate your staff on the dangers of phishing attacks and how to spot them. Ensure your employees know what to look for and how to report any suspicious activity.
- Conditional access is an effective way to prevent unauthorised access to your network from external locations. By setting policies allowing access only from trusted devices or locations, you can ensure your network remains secure. You can also use conditional access to limit access to specific resources or applications, reducing the risk of data breaches.
