Ukraine's problems with cyberattacks aren't over -- far from it. The country reports that intruders attacked the network for Kiev's main airport, Boryspil, last week. Officials aren't accusing any specific party just yet, but they note that the attack originated from a server in Russia. Moreover, there are hints that this might be linked to the power grid attacks from December, which leaned on a common trojan (BlackEnergy) to get in.
There's no known evidence that the airport is the victim of a state-sponsored attack, but the Ukrainian government isn't waiting for answers to take action. It's launching a review of antivirus databases for key transportation systems, and its Computer Emergency Response Team is asking system administrators nationwide to double-check their traffic. Whoever's responsible, this isn't going to help the already very tense relations between Ukraine and Russia.
