Ukrainian hackers take out hundreds of Russian space research servers and supercomputers


The cyber warfare between Russia and Ukraine continues as hackers from the latter launch an attack and destroy the database and infrastructure of Russia’s Far Eastern Research Center of Space Hydrometeorology, “Planeta”.

According to Ukraine’s military intelligence agency, the attack resulted in two petabytes of data and 280 servers being destroyed. Additionally, a digital array valued at US$10 million was also lost in the attack, as well as disabling the research centre’s supercomputers beyond repair through the destruction of software.

“One such computing device together with software costs US$350,000. In the conditions of strict sanctions against Russia, to get such a software again it is impossible,” wrote Ukrainian Defence.

Data included satellite and meteorological data used by the Roscosmos space agency, Russian Defence, emergency situations ministries and other government departments.

Adding salt to the wound, airconditioning, emergency power, and humidification systems were also disabled.

“In total, dozens of strategic companies of the Russian Federation, which work on ‘defense’ and play a key role in supporting Russian occupation troops, will remain without critically important information and services for a long time,” the agency added.

“Glory to Ukraine!”

The attack is the latest in a series between Ukraine and Russia, with the latter recently disabling Ukraine’s largest telco, Kyivstar.

The attack, which occurred in December last year, resulted in service outages the telco originally said were the fault of a technical failure, before confirming a cyber attack.

The attack left Kyivstar’s over 25 million customer base, over half the country’s population, without mobile and home internet services.

A day after the incident, the attack was claimed by Russian hackers from the Solntsepek group, which said they wiped thousands of servers and 10,000 computers.

“We, the Solntsepek hackers, take full responsibility for the cyber attack on Kyivstar. We destroyed 10 thousand computers, more than 4 thousand servers, all cloud storage and backup systems,” said the group on Telegram.

“We attacked Kyivstar because the…

Ukrainian Police Arrest Cryptojacking Hacker


The Ukrainian National Police said on Friday that they had arrested a hacker in the southern city of Mykolaiv in connection with a sophisticated scheme to hijack cloud computers to mine cryptocurrencies, a ploy known as “cryptojacking.”

Ukraine HackerUkrainian police seized electronic devices, SIM and bank card from the suspected hacker. (Photo: Національна поліція України, License)Over the last two years, the 29-year-old suspect allegedly managed to mine nearly US$2 million in cryptocurrencies. The authorities did not release either the suspect’s name or the name of the U.S. company whose server was allegedly misused.

The suspect is accused of infecting that server with malware, known as a “miner virus” — malicious software that steals a computer’s resources to generate cryptocurrency, allowing the hacker to steal money and transfer it to controlled electronic wallets.

According to the police, the suspect hacked 1,500 accounts belonging to the unnamed company’s clients, using a technique known as brute force—self-developed software for automatic password selection.

He then used the compromised accounts to gain access to the cloud computing provider, secretly infecting the company’s server with the malicious software.

The suspect used its computational power to mine cryptocurrencies, allowing him to avoid paying for server time and power.

The stolen computer time typically cost more than the profits mined, so that compromised account holders were left with substantial cloud bills.

During the search of the suspect’s home, the police seized “computer equipment, bank and SIM cards, electronic media, and other evidence of illegal activity.”

The investigation into the case continues, with authorities targeting potential accomplices of the suspect and examining his possible connections with a pro-Russian hacker group, according to Ukrainian police.

Europol, the European Union Agency for Law Enforcement Cooperation, which supported the operation, said that the arrest followed “months of intensive collaboration between Ukrainian authorities, Europol and a cloud provider, who worked tirelessly to identify and locate the individual behind the…

Hackers from the Blackjack group, allegedly related to the Security Service of Ukraine (SBU), hacked the Moscow Internet provider M9com and demolished its servers, an informed source told Interfax-Ukraine on Tuesday.

Data from the company’s mail server and client databases were also posted online. Hackers called the attack on M9com a “warm-up” as part of a retaliation campaign for a hacker attack on the servers of the Ukrainian mobile operator Kyivstar.
