Cyber security experts say this week's attack on at least 14 US airport websites, including those in Los Angeles and Chicago, appears to be the work of a Russian hacker group. As Voice of Aerica correspondent Mike O'Sullivan reports, the outages did not cause major problems for airline passengers, but experts say they highlight a major threat.
The disabling attack targeted the websites of 14 US airports, flooding them with traffic in an attempt to shut them down or make them difficult to use.
According to experts, the attack was carried out by the Russian hacker group "Killnet", which has tens of thousands of followers on its channels on "Telegram", a platform that is widely used in Russia and Ukraine.
Russian hackers are retaliating against Western sanctions against Russia over the war in Ukraine, which they call an act of aggression.
"They have claimed that any group that is on the side of Ukraine or that provides support to Ukraine is contributing to this aggression against Russia. That is why they are carrying out these cyber attacks. "I remember in May 2022, Killnet officially declared war on 10 countries, including the US, Great Britain, Germany and Italy," says Cyber Threat Intelligence analyst Ivan Righi.
"Killnet" is fighting the cyber war, while the physical war continues. On October 8, an explosion damaged the bridge connecting Russia and the occupied Crimean peninsula.
The Russians retaliated.
Experts and a senior US official say there is still no evidence that the Russian government is behind this cyber attack. According to them, the influence of the hackers was limited.
"They are attacking critical organizations, but they are not actually targeting the organization directly. They are attacking the websites connected to these organizations, which really have nothing to do with the operations", assesses the deputy head of intelligence analysis at the "Mandiant" organization.
Airline operations were not affected.
Hackers display varying skill levels, from novice to expert, and they publish their successes.
"They are very interested in the attention in the media as this is how they have built the image of a successful group", assesses analyst Ivan Righi.
Although they have star status in Russia, experts say the damage from attacks like this latest one is minimal.
"They are really superficial, they are short-term attacks, but at the end of the day, they are not easy to ignore," says Mr. Hultquist of the Mandiant organization.
The expert from the Mandiant organization says that such attacks are likely to continue.
