The hacker collective Anonymous Sudan released on Thursday a list of Israeli airlines and tourism companies that they claim have been targeted in cyber attacks.
The sites affected include Arkia, El Al, Israir, and Challenge Airlines IL.
The hackers, who reportedly support the Palestinian cause, have issued a warning that the attacks will continue until Friday, with a major assault expected at the conclusion of their campaign.
In recent days, the group has successfully taken down numerous websites using a potent Russian-developed offensive cyber tool, according to industry experts.
