AmiMoJo shares a BBC report: Christoph Brandstatter is managing director of the four-star Seehotel, Jagerwirt, in Austria's Alps. His hotel's electronic door locks and other systems were hacked for ransom four times, between December 2016 and January 2017. "We got a ransomware mail which was hidden in a bill from Telekom Austria." His hotel's door keys became unusable after he clicked on a link to his bill. So was his hard drive. "Actually, as a small business you do not really think that anybody's interested in you for hacking, so we had no plan what to do," he recalls. He paid a ransom of two bitcoins, saying "at that time it was about $1,882." He has now installed firewalls and new antivirus software, and has trained his staff to recognise phishing emails that may seem genuine but actually contain malware. And he's moved back to traditional metal keys.
