In December, hackers successfully cut off a fifth of the electricity in the city of Kiev. A first which could only be a trial run.
It is a discovery that is cold in the back. According to two cybersecurity firms, the power grid in the city of Kiev was hacked last December. For an hour, a fifth of the city had their electricity cut. At the time, nothing abnormal was detected. But in reality, as revealed on Monday June 12 by ESET and Drago Inc., this cut was a sign that the electrical network had been manipulated by a group of hackers.
This attack is the worst ever seen since Stuxnet, the malware used in 2009 by the Israeli intelligence services to remotely stop the Iranian centrifuges. The researchers gave it a code name: Industroyer for ESET, Crash Override for Drago Inc .. A more sophisticated, modifiable and dangerous attack than experts thought so far.
A particularly sophisticated attack
The operation is the second in two years targeting the Ukrainian electricity network. At the same time of the year in 2015, hackers broke into the computers of 3 regional Ukrainian companies and then physically moved to "shut down" regional power stations. The two attacks appear to originate in Russia, but without any certainty, as is customary with cyber attacks.
In the case of Crash Override, the hackers infiltrated the computers of Ukrenergo, the Ukrainian electricity company, without anyone knowing exactly how. From there, their malware automatically analyzed how the network worked and returned data to them before initiating the December power outage. Once made, the attack destroyed all the files inside the infected computers.
A degree of automation rarely achieved
