Attackers conceal phishing lures using invisible Unicode characters

BleepingComputer

Researchers have discovered that cybercriminals are using a technique called ASCII smuggling in their phishing attacks, which involves the use of invisible Unicode characters to bypass email security filters. This method allows malicious links to appear legitimate, making it easier for attackers to trick users into clicking on them. As a result, individuals and organizations may be more susceptible to phishing attempts, leading to potential data breaches or financial loss. Email security systems may struggle to detect these hidden threats, underscoring the need for users to be vigilant when assessing the legitimacy of links in emails. Companies should consider updating their security measures to better identify and mitigate this evolving tactic.
