Zyxel has informed customers about vulnerabilities in their router hardware, advising them to replace affected models to maintain security. Although the article highlights the widespread use of Zyxel routers, critics argue that it exaggerates the risk by referencing millions of users while only a small number of vulnerable models (1,500) were actually identifiable online. Concerns were raised regarding the effectiveness of such replacements and the financial implications for users who have already invested in Zyxel hardware. There is skepticism about the proactive measures taken by Zyxel, questioning the actual impact of replacing these devices on security vs. the costs involved for consumers.
