KRACK (Key Reinstallation Attack) is a Wi-Fi vulnerability discovered in 2017
It exposed a flaw in the WPA2 security protocol
Attackers within range of a network could interfere with the Wi-Fi connection process
This forced devices to reuse encryption keys
The attack did not require the Wi-Fi password
What this allowed
Interception of Wi-Fi traffic
Reading sensitive data
Modification of unencrypted traffic
Higher risk for unpatched and legacy devices
Who was affected
Mobile phones and laptops using WPA2
Home and enterprise Wi-Fi routers
Devices connected to public Wi-Fi networks
Current situation
Security patches released after 2017 fixed the issue
Devices that never received updates may still be vulnerable
Key takeaway
Even strong security protocols can have design flaws
Regular updates and patching are essential
WPA3 offers stronger protection going forward
