Between November 2019 through April 2020, Karen Serobovich Vardanyan also known as Karl Lagerfeld also known as Maneeken illegally accessed computer networks of victim companies to deploy Ryuk ransomware on compromised servers and workstations. Ryuk ransomware is a type of malicious software designed to encrypt data on a victim's computer or network and prevents the victim from accessing the encrypted files until a ransom is paid.

As part of the scheme, ransom payments were extorted from victim companies in exchange for decryption keys to regain access to their data. A ransom note was placed on the computer systems demanding ransom payments in Bitcoin, a form of cryptocurrency, and provided an email address that victims could use to communicate with the cybercriminals.

Vardanyan worked with his co-conspirators to attack a company in Michigan that paid 200 bitcoin or over $1.1 million at the time of payment to restore access to their network. They also attacked a company in Wilsonville, Oregon, and in February 2020 attacked a school in Texas.
