‘Key’ ransomware suspect arrested in Ukraine: Europol

US, European and Ukrainian police have arrested a ringleader of a notorious hacker gang operating from Ukraine which used ransomware to fleece hundreds of millions of euros from their victims, Europol said Tuesday (28 November).

Law enforcement officers swarmed 30 properties in western and central Ukraine including in Kyiv and Cherkasy on the Dnipro River, as well as Vinnytsa and Rivne last Tuesday, the Hague-based Europol said.

“In an unprecedented effort, law enforcement and judicial authorities from seven countries have joined forces with Europol and Eurojust to dismantle and apprehend in Ukraine key figures behind significant ransomware operations,” it said in a statement.

“The operation comes at a critical time as the country grapples with the challenges of Russia’s military aggression against its territory,” Europol added.

Police arrested a 32-year-old man alleged to have been a ringleader in the gang, as well as four accomplices.

More than 20 investigators from France, Germany, Norway and the United States were deployed to Kyiv to help local police.

Meanwhile Europol set up a virtual command post in The Netherlands to analyse data seized during the Ukrainian house searches in real time.

The latest arrests follow police action in 2021 in which 12 suspected ransomware gang members were arrested in Ukraine and Switzerland.

Ransomware attacks typically access vulnerable computer systems and encrypt or steal data, before sending a ransom note demanding payment in exchange for decrypting the data or not releasing it publicly.

In this case the hackers focused their attacks against organisations in 71 countries, infecting some 250 servers “resulting in losses exceeding several hundreds of millions of euros.”

“These cyber actors are known for specifically targeting large corporations, effectively bringing their business to a standstill,” Europol said.

The gang members played different roles, some breaking into networks, others laundering the cryptocurrency payments made by the victims to have their files decrypted.

“Once inside the networks, the attackers remained undetected and gained additional access using other tools in order to compromise as many systems as possible before triggering ransomware attacks,” Europol said.

EU praise

The European Commission’s vice president on Monday praised Ukraine’s fight against corruption, but said additional efforts were needed in the country that hopes to join the European Union.

In November, the Commission recommended that the 27-member EU formally start accession talks once Ukraine satisfies several remaining conditions, including strengthening anti-corruption efforts.

While on a visit to Kyiv on Monday, Commission Vice President Věra Jourová compared current efforts with the situation the country was in back in 2017, saying she was impressed with the improvement.

“… I did not feel the energy and strong intention. Now I am in a totally different state, compared with 2017. I think that Ukrainians are fed up with old Ukraine, and they want a new system. They will want to see institutions well functioning, prosecuting and investigating cases of organized crime corruption at all levels, not only the big fish but also lower levels.”

Jourová, though, said there still were things to be done, including the adoption of a law on lobbying.

“Good laws, strong institutions, and the right people doing the jobs (are needed). I have a very strong feeling that now it’s in place,” she said.

Jourova also stressed that the EU needed “to think about our absorption capacity” when it comes to new members’ accession, and adapt the system.

President Volodymyr Zelenskyy, meanwhile, said he told Commission President Ursula von der Leyen in a telephone conversation that Ukraine would fulfil all EU recommendations before the bloc’s December summit, including pledges on minority rights and the strengthening of anti-corruption bodies.
