The DDoS extortionists who pretend to be "Fancy Bear" exerted pressure on companies in October 2019 with DDoS attacks to get Bitcoins. The extortion letters available to the LSOC from autumn last year and from the current wave are largely identical in text. The Bitcoin addresses differ so that the attackers can check who paid. The attacked companies currently have seven days before four to transfer the bitcoins.

The extortionists announce warning attacks to underline the seriousness of their demands and carry them out. The attacks are characterized by very high bandwidths and long-lasting, great intensity.

In view of the very aggressive behavior of the perpetrators, the LSOC recommends taking the extortion seriously. As soon as they receive a ransom email, companies should proactively activate their DDoS protection systems. If the protection solution is not designed for volume attacks of several hundred Gbps and beyond, it is important to find out how the company-specific protection bandwidth can be increased in the short term and manifested using SLA.

In addition, the LSOC advises the attacked company not to respond to the extortion and instead to report it to the law enforcement authorities. The Alliance for Cybersecurity offers an overview of the respective contact persons for Cybercrime in the individual federal states.
