Ransomware is a type of malware that locks computers and blocks access to files in lieu of a payment. Companies targeted with ransomware must pay the ransom via cryptocurrency or find another way to restore files and rebuild computer networks.

The FBI estimates that at least US$144.35mil in Bitcoin have been paid from 2013 to 2019 as ransom to hackers.

Founded in 1939, Boggi Milano is among the best known premium Italian menswear brands. The company operates about 200 shops in 38 countries.
