Compromised websites possibly the result of DNS redirection attack
A hacktivist group calling itself Kdms Team, known on Twitter as @KdmsTeam and claiming to hail from Palestine, took credit on Twitter for several recent attacks against websites, including those belonging to cross-platform instant messaging service WhatsApp, computer security company AVG Technologies, and anti-virus software company Avira.
Any visitor to those websites within the past 24 hours may have been greeted by the Palestinian national anthem, along with an image containing a message by the hacktivists.
The problem has been reported as a domain name system (DNS) redirection attack stemming from domain name registration company Network Solutions, which manages DNS records for the aforementioned websites. If this is the case, it is unclear how Kdms Team gained access to the records.
