The new malware variant (detected by Trend Micro as Backdoor.Linux.MIRAI.VWIPI and Backdoor.Linux.BASHLITE.AME) was detected in early January of 2019 from a compromised website in Colombia tailoring to security and alarm integration, widening the possible impact to small and big businesses alike according to Palo Alto’s report. Out of the 27 exploits that this Mirai variant uses – previously used to target embedded devices such as IP cameras, network storage devices, and routers via Apache Struts – 11 are new to the malware
Much like prior campaigns, the new botnet variant is capable of scanning for exposed Telnet ports and using default access credentials with infected devices. It is also capable of scanning for specific devices and unpatched

Trend Micro also found the last Mirai variant, Yowai, in January, and cybercriminals are expected to continue using and developing Mirai to exploit the increasing number of IoT devices in the market. Given the larger and more damaging effects of malware that infects business systems, IoT device users are advised to immediately change their default credentials to lock out bad actors using this particular method. Systems should be patched immediately using available updates released by legitimate vendors to remove exploitable vulnerabilities.
