The latest OT/IoT security report from Nozomi Networks Labs finds wiper malware, IoT botnet activity, and the Russia/Ukraine war impacted the threat landscape in the first half of 2022.
Since Russia began its invasion of Ukraine in February 2022, Nozomi Networks Labs researchers saw activity from several types of threat actors, including hacktivists, nation-state APTs, and cyber criminals. They also observed the robust usage of wiper malware, and witnessed the emergence of an Industroyer variant, dubbed Industroyer2, developed to misuse the IEC-104 protocol, which is commonly used in industrial environments.
Additionally, in the first half of 2022, malicious IoT botnet activity was on the rise and growing in sophistication. Nozomi Networks Labs set up a series of honeypots to attract these malicious botnets and capture their activity in order to provide additional insights into how threat actors target IoT. In this research, Nozomi Networks Labs analysts uncovered growing security concerns for both hard-coded passwords and internet interfaces for end-user credentials. From January to June 2022, Nozomi Networks honeypots found:
- March was the most active month with close to 5,000 unique attacker IP addresses collected.
- The top attacker IP addresses were associated with China and the United States.
- “root” and “admin” credentials were most often targeted and used in multiple variations as a way for threat actors to access all system commands and user accounts.
On the vulnerability front, manufacturing and energy continue to be the most vulnerable industries followed by healthcare and commercial facilities. In the first six months of 2022:
- CISA released 560 Common Vulnerabilities and Exposures (CVEs) – down 14% from the second half of 2021
- The number of impacted vendors went up 27%
- Affected products were also up 19% from the second half of 2021
“This year’s cyber threat landscape is complex,” said Roya Gordon, Nozomi Networks OT/IoT Security Research Evangelist. “Many factors including increasing numbers of connected devices, the sophistication of malicious actors, and shifts in attack motivations are increasing the risk for a breach or cyber-physical attack. Fortunately, security defenses are evolving too. Solutions are available now to give critical infrastructure organizations the network visibility, dynamic threat detection, and actionable intelligence they need to minimize risk and maximize resilience.”
