South Korean Web Hosting Provider Pays $1 Million In Ransomware Demand (bleepingcomputer.com)

An anonymous reader writes: Nayana, a web hosting provider based in South Korea, announced it is in the process of paying a three-tier ransom demand of nearly $1 million worth of Bitcoin, following a ransomware infection that encrypted data on customer' servers. The ransomware infection appears has taken place on June 10, but Nayana admitted to the incident two days later, in a statement on its website.

Attackers asked for an initial ransom payment of 550 Bitcoin, which was worth nearly $1.62 million at the time of the request. After two days of negotiations, Nayana staff said they managed to reduce the ransom demand to 397.6 Bitcoin, or nearly $1 million. In a subsequent announcement, Nayana officials stated that they negotiated with the attackers to pay the ransom demand in three installments, due to the company's inability to produce such a large amount of cash in a short period of time.

On Saturday, June 17, the company said it already paid two of the three payment tranches. In subsequent announcements, Nayana updated clients on the server decryption process, saying the entire operation would take up to ten days due to the vast amount of encrypted data. The company said 153 Linux servers were affected, servers which stored the information of more than 3,400 customers.
