According to the investigators no ransom demands were made by the hackers which could indicate that the hospital was targeted by mistake.

12. WestRock, one of the world’s largest paper and packaging companies suffered an attack which affected some of its operational and information technology systems. WestRock is working with security experts on system recovery efforts to minimize the impact on its customers. In a press release the company described the incident as likely leading to a loss of revenue and incremental costs that could affect its bottom line.

13. Palfinger, an Austria-based Hydraulics Engineering company experienced a global cyberattack that took down their e-mail system and disrupted business operations. A security notice titled ‘Cyberattack’ stated that their Enterprise resource planning (ERP) systems were down and that “a large proportion of the group’s worldwide locations were affected.” The company that operates in almost 30 countries has made it official that its email systems were the worst hit in the file encrypting malware related attack.

14. Tennessee Wesleyan University (TWU) revealed in a press release that all of the university’s networks were closed after staff and campus officials became aware of a ransomware attack. Online learning was unaffected but staff and students were asked not to use the university systems.

15. Pan-Asian retail giant Dairy Farm were hit by a REvil ransomware attack with the attackers allegedly demanding a $30 million ransom. The group operates over 10,000 outlets across grocery, convenience store, health and beauty, home furnishing, and restaurants in Asia.

February saw a total of 23 attacks, up from 16 in 2020. South America reported some large attacks including two major utility companies, the Ministry of Finance and Ecuador’s largest bank. The apparent attack on Kia made a lot of headlines during the month as the company continues to dispute the attack, despite the cybercriminals posting their data on the dark web. Here’s a look at what we uncovered for the month.

1. The first reported attack of the month involved Brazilian state-owned energy company Companhia Paranaense de Energia (Copel). The attack was the work of the Darkside gang who claimed to have stolen more than 1000 GB of sensitive data.

The Egregor gang has been linked to the attack.

7. British Columbia-based real estate agency Remax Kelowna was hit with an attack by the Conti ransomware gang who listed them as a victim on their leaks website. According to the firm, the attack occurred at the same time as they were overseeing a software update. They reported that the ransomware was not launched and while some files has been copied, the data was allegedly non-personal in nature.

8. Ness Digital Engineering Company, an Israeli-based U.S. IT provider was hit by Ragnar Locker ransomware affecting its computer networks in India, the U.S. and Israel. The company said that their clients who include government ministries, hospitals, and local municipalities were not compromised in the attack. A screenshot of the ransom note read “Hello ness-digital-engineering! If you (sic) reading this message, it means your network was PENETRATED and all of your files and data has (sic) been ENCRYPTED by RAGNAR LOCKER!” The text then directed the company to get in touch via live chat to make a deal.

An independent security researcher shared a Tor web page acting as a ransom negotiation page with media outlet BleepingComputer. RansomExx was behind the attack.

11. Dax-Côte d’Argent Hospital Center in France was the next reported incident. The attack by the Egregor gang caused major disruptions across their network and forced the hospital to only accept major emergencies. A spokesperson from the hospital administration commented that everything from reading a medical file to the catering system had been affected and the facility was back to pen and paper following the attack.

12. The second education incident of the month goes to Central Piedmont Community College in North Carolina. The school tweeted that they had experienced a ransomware attack, but it’s not known what gang was responsible. It has so far been reported that no employee or student data was compromised.

13. Discount Car and Truck Rental, part of the Enterprise group and one of Canada’s biggest rental agencies, was hit by the Darkside ransomware gang.

14. International law firm Jones Day were the victims of a ransomware attack carried out by the Clop gang. The law firm claimed that its network had not been compromised and that the theft of data involved a file-sharing company that it used to store files. The gang however claimed that they had obtained 100 gigabytes of files from servers belonging to the firm and that they had begun publishing the exfiltrated data as proof of their successful attack.

15. The attack on Kia Motors America is probably the most interesting of the month. The incident became known when it was reported that the company was suffering a major IT outage across the U.S., affecting the internal sites used by dealers, mobile apps, and phone and payment systems. It later transpired that the DoppelPaymer gang has claimed the attack and they had demanded a ransom of $20 million for a decryptor and not to leak the stolen data. The Tor victim page stated that a “huge amount” of data had been exfiltrated and would be released in 2-3 weeks if the company refused to negotiate with the hackers. Kia denied they were under attack. The gang then released data belonging to parent organization Hyundai Motor Company but interesting both are denying the attack. In an official statement Kia described the unavailability of its services, including remote start and heating as an “extended systems outage” that began on February 13th. They continued by saying, “we are aware of online speculation that Kia is subject to a ransomware attack. At this time, and based on the best and most current information, we can confirm that we have no evidence that Kia or any Kia data is subject to a ransomware attack.” It’s hard to imagine that this is a hoax on the part of the cybercriminals and experts say it’s possible but not probable.

16. Yuba County in California was the victim of a ransomware cyberattack which infected some of the county’s computer systems with malware. The malware encrypted the affected systems and the attacker demanded payment from the county in order to obtain a decryption key.

21. Banco Pichincha, Ecuador’s largest private bank was the next victim of the Hotarus Corp gang. Following the attack the bank published an official statement stating that a marketing partner had been hacked and not their internal systems. They confirmed that fraudulent (phishing) emails were sent on behalf of the bank to clients in order to carry out illegitimate transactions. However, in an interview with BleepingComputer, the hacking group disputed the banks statement and said they used the marketing company’s attack as a launchpad into the banks internal systems. They claim to have stolen “31,636,026 Million customer records and 58,456 sensitive system records,” including credit card numbers.

22. Saginaw Township Community Schools in Michigan became the victim of a ransomware attack and the gang behind the attack is unknown.

Systems have been mostly restored but the investigation continues and at this time it is not known if any personal data was compromised in the attack.

23. In the last reported attack of the month, Staring College in the Netherlands reported that had been attacked and that they had paid the ransom.
