Hackers have started adding data-wiping routines to malware that's designed to infect internet-of-things and other embedded devices. Two attacks observed recently displayed this behavior but likely for different purposes. Researchers from Palo Alto Networks found a new malware program dubbed Amnesia that infects digital video recorders through a year-old vulnerability. Amnesia is a variation of an older IoT botnet client called Tsunami, but what makes it interesting is that it attempts to detect whether it's running inside a virtualized environment. The malware performs some checks to determine whether the Linux environment it's running in is actually a virtual machine based on VirtualBox, VMware, or QEMU. Such environments are used by security researchers to build analysis sandboxes or honeypots. Virtual machine detection has existed in Windows malware programs for years, but this is the first time when this feature has been observed in malware built for Linux-ba
