Iranian Hackers Deploy IOCONTROL Malware to Target IoT and OT Devices in the US and Israel

A notorious Iranian hacking group, CyberAv3ngers, has been linked to a series of cyberattacks targeting IoT (Internet of Things) and OT (Operational Technology) devices in the United States and Israel. The custom-built malware behind these attacks, dubbed IOCONTROL, is designed to infiltrate critical infrastructure, raising alarms among cybersecurity experts and governments alike.

State-Sponsored Threats to Critical Infrastructure

CyberAv3ngers, which claims to be a hacktivist group, has been tied to Iran’s Islamic Revolutionary Guard Corps (IRGC). The group has previously targeted industrial control systems (ICS) at water facilities in Ireland and the United States, causing significant disruptions. For instance, in one 2023 attack on a water utility in Pennsylvania, the hackers exploited poorly secured ICS, leading to two days of water supply outages.

The concerning aspect of these attacks is their reliance on basic vulnerabilities. Many ICS and OT devices are left exposed to the internet with default passwords, making them easy targets for attackers without needing advanced hacking techniques. These gaps in security highlight the ongoing risks posed by weak infrastructure protections.

How IOCONTROL Malware Operates

According to researchers at Claroty, IOCONTROL is a cyberweapon specifically designed to target embedded Linux-based devices in IoT and OT environments. The malware is versatile and can be customized for different devices, including:

  • IP Cameras
  • Routers
  • SCADA Systems
  • PLCs (Programmable Logic Controllers)
  • HMIs (Human-Machine Interfaces)
  • Firewalls

Notable vendors affected include Baicells, D-Link, Hikvision, Phoenix Contact, Teltonika, and Unitronics, among others. This broad targeting suggests that the malware can exploit multiple types of devices integral to industrial and operational networks.

IOCONTROL communicates with its operators via the MQTT protocol, a lightweight machine-to-machine communication standard. This allows attackers to execute arbitrary code, perform port scans, and spread malware laterally across networks, gaining deeper control over compromised systems.

Recent High-Profile Attacks

One of the most alarming campaigns occurred in October 2023, when CyberAv3ngers claimed to have disrupted 200 gas pumps in Israel. The attack exploited devices linked to Orpak Systems, a company providing gas station management solutions.

Claroty’s analysis of IOCONTROL revealed a sample obtained from a Gasboy fuel control system—closely tied to Orpak—indicating that the group had potentially relaunched its campaign in mid-2024. Despite ongoing investigations, it remains unclear how the malware was initially distributed.

The Broader Implications

The attacks attributed to IOCONTROL highlight the increasing focus on civilian critical infrastructure as a target for state-sponsored cyber campaigns. By exploiting IoT and OT vulnerabilities, groups like CyberAv3ngers can cause widespread disruptions, from interrupting water supplies to halting fuel distribution. These actions not only pose risks to public safety but also create geopolitical tension.

In response, the US government has offered a reward of up to $10 million for information leading to the identification or arrest of individuals associated with CyberAv3ngers. This underscores the seriousness of these cyber threats and the urgent need for stronger defenses against them.

Protecting Against IOCONTROL and Similar Threats

Organizations managing IoT and OT devices should take the following steps to mitigate risks:

  1. Change Default Credentials: Many attacks succeed because of weak, factory-default passwords. Implement strong password policies immediately.
  2. Network Segmentation: Isolate ICS and OT devices from internet-facing networks to limit potential access points for attackers.
  3. Regular Updates and Patching: Ensure all devices are running the latest firmware and security updates.
  4. Monitor for Anomalies: Deploy intrusion detection systems to identify unusual activity, such as port scans or unauthorized access attempts.
  5. Limit Remote Access: Restrict access to ICS and OT devices, allowing connections only from trusted IP addresses.

Final Words

The IOCONTROL malware campaign is a stark reminder of the vulnerabilities inherent in IoT and OT systems. As state-sponsored groups like CyberAv3ngers increasingly target critical infrastructure, organizations must adopt proactive cybersecurity measures to defend against these evolving threats. By securing their networks, they can prevent attacks that could have devastating impacts on public safety and essential services.
