The US and European Union on Tuesday mentioned Russia was accountable for a cyberattack in February that crippled a satellite network in Ukraine and neighboring international locations, disrupting communications and a wind farm used to generate electrical energy.

The February 24 assault unleashed wiper malware that destroyed thousands of satellite modems utilized by prospects of communications firm Viasat. A month later, safety agency SentinelOne mentioned an evaluation of the wiper malware used within the assault shared a number of technical similarities to VPNFilter, a bit of malware found on greater than 500,000 home and small office modems in 2018. A number of US authorities businesses attributed VPNFilter to Russian state risk actors.

Tens of 1000’s of modems taken out by AcidRain

“At present, in help of the European Union and different companions, the USA is sharing publicly its evaluation that Russia launched cyber assaults in late February in opposition to business satellite communications networks to disrupt Ukrainian command and management through the invasion, and these actions had spillover impacts into different European international locations,” US Secretary of State Antony Blinken wrote in a statement. “The exercise disabled very small aperture terminals in Ukraine and throughout Europe. This consists of tens of 1000’s of terminals exterior of Ukraine that, amongst different issues, help wind generators and present Web companies to personal residents.”

AcidRain, the title of the wiper analyzed by SentinelOne, is a beforehand unknown piece of malware. Consisting of an executable file for the MIPS {hardware} in Viasat modems, AcidRain is the seventh distinct piece of wiper malware related to Russia’s ongoing invasion of Ukraine. Wipers destroy information on arduous drives in a manner that can’t be reversed. Generally, they render units or whole networks fully unusable.

SentinelOne researchers mentioned they discovered “non-trivial” however finally “inconclusive” developmental similarities between AcidRain and “dstr,” the title of a wiper module in VPNFilter. The resemblances included a 55 % code similarity as measured by a instrument often known as TLSH, equivalent part header strings tables, and the “storing of the earlier syscall quantity to a worldwide location earlier than a brand new syscall.”

Viasat officers mentioned on the time that the SentinelOne evaluation and findings have been in line with the result of their very own investigation.

One of many first indicators of the hack occurred when greater than 5,800 wind generators belonging to the German power firm Enercon have been knocked offline. The outage didn’t cease the generators from spinning, nevertheless it prevented engineers from remotely resetting them. Enercon has since managed to get many of the affected generators again on-line and change the satellite modems.

“The cyberattack took place one hour earlier than Russia’s unprovoked and unjustified invasion of Ukraine on 24 February 2022 thus facilitating the navy aggression,” EU officers wrote in an official statement. “This cyberattack had a big impression inflicting indiscriminate communication outages and disruptions throughout a number of public authorities, companies and customers in Ukraine, in addition to affecting a number of EU Member States.”

In a separate statement, British International Secretary Liz Truss mentioned: “That is clear and stunning proof of a deliberate and malicious assault by Russia in opposition to Ukraine which had vital penalties on odd folks and companies in Ukraine and throughout Europe.”

Repeat cyber offender

The cyberattack was one among many Russia has carried out in opposition to Ukraine over the previous eight years. In 2015 and once more in 2016, hackers working for the Kremlin prompted electrical energy blackouts that left tons of of 1000’s of Ukrainians with out warmth throughout one of many coldest months.

Beginning round January 2022, within the lead-up to Russia’s invasion of its neighboring nation, Russia unleashed a bunch of different cyberattacks in opposition to Ukrainian targets, together with a sequence of distributed denial-of-service assaults, web site defacements, and wiper attacks.

Moreover the 2 assaults on Ukrainian electrical energy infrastructure, proof exhibits Russia can be accountable for NotPetya, one other disk wiper that was launched in Ukraine and later unfold world wide, the place it prompted an estimated $10 billion in injury. In 2018, the US sanctioned Russia for the NotPetya assault and interference within the 2016 election.

Critics have lengthy said that the US and its allies didn’t do sufficient to punish Russia for NotPetya or the 2015 or 2016 assaults on Ukraine, which stay the one identified real-world hacks to knock out electrical energy.
