On May 11, 2021, D-Link became aware of the public disclosure of "FragAttack", a collection of security vulnerabilities that affect Wi-Fi devices.
D-Link is investigating these reported security issues and if any D-Link Brand WiFi products are affected by these vulnerable.


The Industry Consortium for Advancement of Security on the Internet (ICASI) recently disclosed this collection of security vulnerabilities called FragAttacks (fragmentation and aggregation attacks) affecting Wi-Fi devices. Some vulnerabilities are widespread design flaws in the Wi-Fi standard or widespread programming mistakes in Wi-Fi products.
