KYIV, Ukraine (AP) — Hackers on Friday briefly shut down dozens of Ukrainian authorities web sites, inflicting no main harm however including to simmering tensions whereas Russia amasses troops on the Ukrainian border. Separately, in a uncommon gesture to the U.S. at a time of chilly relations, Russia stated it had arrested members of a significant ransomware gang that focused U.S. entities.
The occasions, although seemingly unrelated, got here throughout a frenetic interval of exercise because the U.S. publicly accused Moscow of getting ready an extra invasion of Ukraine and of creating a pretext to do so. They underscored how cybersecurity stays a pivotal concern — that the escalating animosity dangers not solely precise violence but in addition damaging digital assaults that would have an effect on Ukraine and even the U.S.
The White House stated Friday that President Joe Biden had been briefed on the disruptions, which focused about 70 web sites of nationwide and regional authorities our bodies, but it surely didn’t point out who may be accountable.

But even with none attribution of duty, suspicions had been solid on Russia, with its historical past of peppering Ukraine with damaging cyberattacks. Ukraine’s Security Service, the SBU, stated preliminary outcomes of an investigation indicated involvement of “hacker teams linked to Russia’s intelligence providers.” It stated most of the web sites had resumed operations, and that content material was not altered and private information not leaked. The SBU stated the culprits “hacked the infrastructure of a industrial firm that had entry, with administrator privileges, to web sites affected by the assault.”
The White House stated it was nonetheless assessing the affect of the defacements however described it as “restricted” thus far. It didn’t instantly touch upon a separate, and curious, growth — the arrests by Russian intelligence officers of alleged ransomware gang members, an operation Moscow stated was performed on the request of U.S. authorities.
Russia’s previous cyber operations in opposition to Ukraine embody a hack of its voting system earlier than 2014 nationwide elections and of its energy grid in 2015 and 2016. In 2017, Russia unleashed one of probably the most damaging cyberattacks on report with the NotPetya virus, which focused Ukrainian companies and induced greater than $10 billion in harm globally. Moscow has beforehand denied involvement in cyberattacks in opposition to Ukraine.
Ukrainian cybersecurity professionals, aided by the U.S., have been fortifying the defenses of vital infrastructure ever since. NATO Secretary-General Jens Stoltenberg stated Friday the alliance will proceed to present “robust political and sensible help” to Ukraine in mild of the cyberattacks.
Experts say Russian President Vladimir Putin may use cyberattacks to destabilize Ukraine and different ex-Soviet international locations that want to be a part of NATO with out having to commit troops. Tensions between Ukraine and Russia are excessive, with Moscow amassing an estimated 100,000 troops close to its intensive border with Ukraine.
“If you’re making an attempt to use it as a stage and a deterrent to cease folks from shifting ahead with NATO consideration or different issues, cyber is ideal,” Tim Conway, a cybersecurity teacher on the SANS Institute, informed the AP final week.
The major query for the web site defacements is whether or not they’re the work of Russian freelancers or half of a bigger state-backed operation, stated Oleh Derevianko, a number one personal sector professional and founder of the ISSP cybersecurity agency.
A message posted by the hackers in Russian, Ukrainian and Polish claimed Ukrainians’ private information had been positioned on-line and destroyed. It informed Ukrainians to “be afraid and count on the worst.” In response, Poland’s authorities famous Russia has an extended historical past of disinformation campaigns and that the Polish within the message was error-ridden and clearly not from a local speaker.
Researchers from the worldwide danger suppose tank Eurasia Group stated the Ukraine defacements don’t “essentially level to an imminent escalation of hostilities by Russia” — they rank low on its ladder of cyber choices. They stated Friday’s assault quantities “to trolling, sending a message that Ukraine may see worse to come.”
The defacements adopted a 12 months wherein cybersecurity grew to become a high concern as a result of of a Russian-government cyberespionage marketing campaign focusing on U.S. authorities businesses and ransomware assaults launched by Russia-based legal gangs.
On Friday, Russia’s Federal Security Service, or FSB, introduced the detention of members of the REvil ransomware gang. The group was behind final 12 months’s Fourth of July weekend supply-chain assault focusing on the software program agency Kaseya, which crippled greater than 1,000 companies and public organizations globally.
The FSB claimed to have dismantled the gang, however REvil successfully disbanded in July. Cybersecurity consultants say its members largely moved to different ransomware syndicates. They solid doubt Friday on whether or not the arrests would considerably have an effect on ransomware gangs, whose actions have solely reasonably eased after high-profile assaults on vital U.S. infrastructure final 12 months, together with the Colonial Pipeline.
The FSB stated it raided the houses of 14 group members and seized over 426 million rubles ($5.6 million), together with in cryptocurrency, in addition to computer systems, crypto wallets and 20 elite vehicles “purchased with cash obtained by legal means.” All these detained have been charged with “unlawful circulation of means of cost,” a legal offense punishable by up to six years in jail. The suspects weren’t named.
According to the FSB, the operation was performed on the request of U.S. authorities, who had recognized the group’s chief. It’s the primary important public motion by Russian authorities since Biden warned Putin final summer time that he wanted to crack down on ransomware gangs.
Experts stated it was too early to know if the arrests sign a significant Kremlin crackdown on ransomware criminals — or if they could simply have been a piecemeal effort to appease the White House.
“The follow-through on sentencing will ship the strongest sign a technique or one other as to IF there has really been a change in how tolerant Russia might be sooner or later to cyber criminals,” Bill Siegel, CEO of the ransomware response agency Coveware, stated in an e-mail.
Yelisey Boguslavskiy, analysis director at Advanced Intelligence, stated these arrested are possible low-level associates — not the individuals who ran the ransomware-as-a-service, which disbanded in July. REvil additionally apparently ripped off some associates so it had enemies within the underground, he stated.
REvil’s assaults crippled tens of hundreds of computer systems worldwide and yielded not less than $200 million in ransom funds, Attorney General Merrick Garland stated in November when saying costs in opposition to two hackers affiliated with the gang.
Such assaults drew important consideration from legislation enforcement officers all over the world. Hours earlier than the U.S. introduced its arrests, European legislation enforcement officers revealed the outcomes of a months-long, 17-nation operation that yielded the arrests of seven hackers linked to REvil and one other ransomware household.
The AP reported final 12 months that U.S. officers, in the meantime, shared a small quantity of names of suspected ransomware operators with Russian officers, who stated they had been investigating.
Brett Callow, a ransomware analyst with the cybersecurity agency Emsisoft, stated no matter Russia’s motivations could also be, the arrests would “actually ship shockwaves by means of the cybercrime neighborhood. The gang’s former associates and enterprise associates will invariably be involved in regards to the implications.”
