The use of crypto-ransomware in targeted attacks has become an ordinary occurrence lately: new incidents are being reported every month, sometimes even more often.
On July 23, Garmin, a major manufacturer of navigation equipment and smart devices, including smart watches and bracelets, experienced a massive service outage. As confirmed by an official statement later, the cause of the downtime was a cybersecurity incident involving data encryption. The situation was so dire that at the time of writing of this post (7/29) the operation of the affected online services had not been fully restored.
According to currently available information, the attack saw the threat actors use a targeted build of the trojan WastedLocker. An increase in the activity of this malware was noticed in the first half of this year.
