A New Mirai based IoT RAT Spreading Through 2 0-day Vulnerabilities

Netlab observed a new IoT botnet exploits two Tenda router 0-day vulnerabilities to install a Remote Access Trojan (RAT).

The botnet dubbed Ttint was found to be active since November 2019, along with DDoS capabilities it includes 12 remote access functions.

Ttint IoT Botnet Attack

Attackers used following Tenda router 0-day vulnerability (CVE-2018-14558 & CVE-2020-10987) to distribute the Ttint samples.

The Tint remote access Trojan based on Mirai code, it includes 10 Mirai DDoS attack instructions & 12 control instructions such as Socket5 proxy for router devices, tampering with router DNS, setting iptables, executing custom system commands.

Once the Ttint gets executed “it deletes its files, manipulates the watchdog, and prevents the device from restarting, it runs as a single instance by binding the port; then modifies the process name to confuse the user; it finally establishes a connection with the decrypted C2, Reporting device information.”

Ttint Bot supports for 22 commands, 10 DDoS commands inherited from Mirai, and 12 new commands.

12run “nc” command
13run “ls” command
15Execute system commands
16Tampering with router DNS
18Report device information
14Config iptables
11run “ifconfig” command
19Open Socks5 proxy
20Close Socks5 proxy
22Reverse shell

According to Netlab analysis, “the attacker first used a Google cloud service IP, and then switched to a hosting provider in Hong Kong.”

All the communication with the C2 server is encrypted and for communication, it uses WSS (WebSocket over TLS) protocol.

As with any new technology, IoT promises to be the future of the Internet, bringing better connectivity and ease of use of the devices we use, but as these two botnet attacks show, an equal amount of stress must be placed on security.

Tenda router users are recommended to check their device firmware and make the necessary update, here you can find the IoCs.

Low Rate DDoS Attack

9 of 10 sites on the AppTrana network have faced a DDoS attack in the last 30 days.
Some DDoS attacks could readily be blocked by rate-limiting, IP reputation checks and other basic mitigation methods.
More than 50% of the DDoS attacks are employing botnets to send slow DDoS attacks where millions of IPs are being employed to send one or two requests per minute..
Key takeaways include:

  • The mechanics of a low-DDoS attack
  • Fundamentals of behavioural AI and rate-limiting
  • Surgical mitigation actions to minimize false positives
  • Role of managed services in DDoS monitoring
