Protonmail, an email firm located in Switzerland, has reputedly paid a figure in excess of £3,600 to prevent cyber criminals from flooding its site with data, but attacks continue to cripple the company.
The company was warned ahead of the initial distributed denial of service (DDoS) attack when a demand for money was made and ignored. A DDoS attack then followed, which halted service on the site for about 15 minutes. The following day, another attack hit the site, halting its service and affecting hundreds of other companies using the same internet service provider. Protonmail then agreed to pay the 15 bitcoin ransom, only to find that attacks were still coming.
Swiss Agencies have stated that the crime was carried out by a group called the Armada Collective which has targeted other Swiss organisations over the last few weeks. Their advice has been to resist any ransom demands and instead seek guidance from experts as to the best way to rebuff an attack.
