Managed.com has taken their servers and web hosting systems offline as they struggle to recover from a weekend REvil ransomware attack. Ransomware-as-a-Service known as REvil demands a $500,000 ransom in Monero to receive a decryptor. At the time of this writing, websites for clients continue to be unavailable, leading to some clients switching their web hosting to another provider. REvil has been responsible for large attacks in the past, including Travelex, Kenneth Cole, SeaChange, Brown-Forman and celebrity law firm.
