The German newspaper Handelsblatt beforehand reported that the hackers used the Black Cat ransomware, citing a report from Germany’s Federal Workplace for Data Safety. The 2 individuals accustomed to the investigation confirmed that account to Bloomberg Information.
Black Cat’s ransomware code is written in Russian and is thought for its “sophistication and innovation,” in response to a report printed in January by researchers at Unit 42, a cybersecurity crew at Palo Alto Networks. The gang, which has been energetic since November 2021, has recruited “associates” on cybercrime boards who successfully hire out the ransomware to hack corporations and organizations, in response to the report.
