Cybersecurity News Roundup: Week of August 29, 2022

The country’s Interior Ministry reported last week that a government agency had had its systems and online services disrupted by ransomware targeting Windows and VMware ESXi servers. In the Dominican Republic, the country’s national cybersecurity center said on August 24 that the Dominican Agrarian Institute (IAD) of its Ministry of Agriculture was targeted. He has, so far, refused to pay the $650,000 ransom. Earlier in August, Argentina’s justice system in Córdoba was hit with ransomware, forcing the organization to shut down systems and services.

The Balkan country of Montenegro has also been hit with ransomware, and the hackers are demanding a whopping $10 million. The attack, which targeted its critical infrastructure, struck on August 19. According beeping computer, several government spokesmen initially blamed the incident on “Russian services”. However, the Cuba ransomware gang claimed responsibility for the attack.

The Portuguese public airline TAP Air Portugal is the victim of an attack carried out by the ransomware gang Ragner Locker. First disclosed on August 26, the incident appeared to have been successfully blocked. The company, at the time, said it found no evidence of improper access to customer data.

In the UK, a massive cyberattack on its National Health Service (NHS) has continued to wreak havoc since the incident was announced in early August. This week the NHS announced that some services could be offline for another three months. The attack impacted key services, including those used for patient records and medical notes. As a result, some staff had to rely on pen and paper. It is also likely that it will take months to process the increasing amounts of medical documents.

NATO is investigating the leak of data allegedly stolen from European missile systems company MBDA Missile Systems, which hackers put up for sale on the Dark Web. According to a recent BBC History the data includes blueprints of weapons used by NATO allies during the Ukraine War. MBDA Missile Systems has admitted that its data was stolen but claims that no classified files were part of it. Information was hacked from a compromised external hard drive. The data was leaked to be sold on Russian and English language forums after MBDA refused to pay the nearly $300,000 ransom.

Student loan holders from the Oklahoma Student Loan Authority (OSLA) and EdFinancial received bad news this week about a data breach via Nelnet Servicing.
