is a tag in HTML that is used to create a division or section in a webpage. It is a useful tool for organizing content and applying styles to specific sections. In this article, we learn about a new phishing campaign that uses HTML files to conceal malicious scripts. The attack involves an email disguised as an urgent company-related payment request with an HTML attachment. Once the user opens the HTML file, they are redirected to a spoofed Microsoft login page, where they are prompted to enter their credentials. This attack underscores the importance of email security and the need for comprehensive solutions that can detect and remediate deceptive threats in enterprise users’ inboxes.

The attack is more sophisticated than typical phishing models. The HTML attachment is encoded and contains multiple layers of obfuscation. Standard email security systems may overlook these complex layers, making it difficult to detect the malicious script. However, advanced email security solutions that harness image recognition technologies can help detect even the subtlest of phishing scams. Organizations can also integrate incident response services into their cybersecurity solutions to proactively prevent and remediate attacks.

Phishing attacks are becoming increasingly prevalent and sophisticated. According to Perception Point’s latest Cybersecurity Trends Report, advanced phishing attacks skyrocketed by 436% in 2022. This highlights the need for organizations to prioritize email security and deploy multi-layered security solutions to protect sensitive personal data. While it is important for employees to exercise caution and scrutiny when dealing with emails, it is also crucial for organizations to take proactive measures to prevent and remediate attacks.
