![]() ![]() Huawei was informed of the vulnerability on November 27, a few days later it published a security advisory that notified the issue to the users and provided the following recommendations to prevent the exploitation of the flaw:“The customers can deploy Huawei NGFWs (Next Generation Firewall) or data center firewalls, and upgrade the IPS signature database to the latest version IPS_H20011000_2017120100 released on Decemto detect and defend against this vulnerability exploits initiated from the Internet,” reads the advisory published by Huawei.Experts noticed that the Satori bot floods targets with manually crafted UDP or TCP packets, it first attempts to resolve the IP address of a C&C server using DNS request with the hardcoded domain name, then gets the addresses from the DNS response and tries to connect via TCP on the hardcoded target port (7645).The C&C server, in turn, provides the number of packets used for the flooding action and their corresponding parameters, and can also pass an individual IP for attack or a subnet. This service is supposedly carrying out a firmware upgrade action by sending a request to “/ctrlt/DeviceUpgrade_1″ (referred to as controlURL ) and is carried out with two elements named`NewStatusURL` and `NewDownloadURL`,” continues the analysis.“The vulnerability allows remote administrators to execute arbitrary commands by injecting shell meta-characters “$()” in the NewStatusURL and NewDownloadURL.” The attackers exploited the vulnerability to download and execute the Satori bot. From looking into the UPnP description of the device, it can be seen that it supports a service type named `DeviceUpgrade`. A variant of Satori was discovered which attacks Ethereum mining clients,” states the report published by NetScout.Below the key findings for the new Mirai variants discovered by the experts:In December 2017, security experts from Check Point Security firm discovered a new variant of the Mirai botnet dubbed Satori that was responsible for hundreds of thousands of attempts to exploit a recently discovered vulnerability in Huawei HG532 home routers.The activity of the Satori botnet has been observed over the past month by researchers from Check Point security.The new botnet attempted to compromise Huawei HG532 devices in several countries, including the USA, Italy, Germany, and Egypt.The attacks associated with the new botnet attempted to exploit the CVE-2017-17215 zero-day vulnerability in the Huawei home router caused by the fact that the TR-064 technical report standard, which was designed for local network configuration, was exposed to WAN through port 37215 (UPnP – Universal Plug and Play).“In this case though, the TR-064 implementation in the Huawei devices was exposed to WAN through port 37215 (UPnP). The Mirai source is not limited to only DDoS attacks. We analyze your responses and can determine when you are ready to sit for the test.Since the release of the source code of the Mirai botnet, crooks have improved their own versions by implementing new functionalities and by adding new exploits.A recent report published by NetScout’s Arbor Security Engineering and Response Team (ASERT) confirmed the intense activities of threat actors related to the Mirai botnet, in a few months experts spotted at least four Mirai variants in the wild tracked as Satori, JenX, OMG, and Wicked.The availability of the Mirai source code allows malware author to create their own version.“Using Mirai as a framework, botnet authors can quickly add in new exploits and functionally, thus dramatically decreasing the development time for botnets.
