- Cybersecurity experts have identified a new vulnerability in Microsoft 365’s antiphishing feature, which can be bypassed using CSS style tags.
- This revelation raises significant concerns about the robustness of current security measures and the need for immediate updates to protect users.
Microsoft 365, which is widely used by businesses and organizations, has a critical flaw in its antiphishing system. Attackers are using CSS style tags to bypass this security feature and thus allow phishing emails to go unnoticed by the users’ systems. It involves embedding malicious content into CSS code, something that the antiphishing does not identify as dangerous.
Various cybersecurity firms’ experts are concerned that it is quite complex to detect such technique. They use CSS to hide malicious links and contents from the antiphishing filter so they look harmless. Consequently, naïve individuals may become victims of phishing activities hence compromising sensitive information or even organization’s security.
Microsoft has admitted this problem and is working on solving it. However, it takes time for them to develop and deploy updates, leaving the users open to potential risks at their unsure moment. In turn, security professionals recommend extra precautions like two-factor authentication or training staffs about different aspects related to email employees do scams.
This event just demonstrates how dynamic cyber threats have become today, calling for flexible defense mechanisms. Moreover, organizations must realize that they must be kept well-informed about any loopholes that could provide entrance points for unwanted intruders.
