New Fodcha Botnet Attacks More Than 100 Victims Daily

Qihoo 360 (360 Netlab) experts report the discovery of a new Fodcha botnet that launches DDoS attacks on hundreds of victims every day. According to the company, the threat is growing rapidly and is replenished with new bots, including routers, DRVs and vulnerable servers.

From March 29 to April 10, the Fodcha botnet included more than 62,000 devices. The number of unique IP addresses associated with the malware fluctuates, with experts monitoring around 10,000 Fodcha bots using Chinese IP addresses every day, with most of them using the services of China Unicom (59.9%) and China Telecom (39.4%).

Based on direct data that we received from the information security community, the number of live bots exceeds 56,000 daily. The dissemination looks pretty massive, with over 10,000 active bots (IPs) registered daily in China alone, as well as over 100 DDoS attack victims daily.the experts write.

Fodcha is known to infect new devices using exploits designed to use vulnerabilities in a number of devices, as well as the Crazyfia brute force tool. The list of devices and services that Fodcha attacks include:

  1. Android: Android ADB Debug Server RCE;
  2. GitLab: CVE-2021-22205;
  3. Realtek Jungle SDK: CVE-2021-35394;
  4. MVPower DVR: unauthenticated execution of shell commands in JAWS Webserver;
  6. TOTOLINK Routers: backdoor in TOTOLINK routers;
  7. ZHONE Router: Web RCE in ZHONE routers.

Fodcha operators use the results of Crazyfia scans to gain access to vulnerable devices and then deploy malware payloads on them. Experts write that the botnet can be capable of MIPS, MPSL, ARM, x86 and other architectures.

The botnet is known to have been using folded[.]in as the domain for the command-and-control server since January 2022, and switched to fridgexperts[.]cc in March when the cloud service provider disabled the first domain.

The new C&C server maps to over a dozen IP addresses and is distributed across multiple countries including the US, Korea, Japan, and India, and more cloud providers associated with it, including Amazon, DediPath, DigitalOcean, Linode, and more.the Qihoo 360 report noted.

Let me remind you that we also wrote that U.S. Authorities Disrupt Cyclops Blink Botnet, and that FritzFrog botnet is active again.

I was always interested in computer sciences, especially data security and the theme, which is called nowadays "data science", since my early teens. Before coming into the Virus Removal team as Editor-in-chief, I worked as a cybersecurity expert in several companies, including one of Amazon's contractors. Another experience: I have got is teaching in Arden and Reading universities.
