Called Ransomware for IoT or R4IoT by Forescout, it's a "Novel, proof-of-concept ransomware that exploits an IoT device to gain access and move laterally in an IT network and impact the OT network." This potential pivot is based on the rapid growth in the number of IoT devices as well as the convergence of IT and OT networks in organizations.

The security firm's Vedere Labs team said it developed a proof-of-concept strain of this type of next-generation malware, which they called R4IoT. After gaining initial access via IoT devices, the malware moves laterally through the IT network, deploying ransomware and cryptocurrency miners while also exfiltrating data, before taking advantage of operational technology systems to potentially physically disrupt critical business operations, such as pipelines or manufacturing equipment. These types of increasingly destructive attacks, combined with the growing number of internet-connected devices led the researchers to consider: what if ransomware exploited IoT gear to get into a corporate network.

A group of academics has devised a system that can be used on a phone or a laptop to identify and locate Wi-Fi-connected hidden IoT devices in unfamiliar physical spaces. With hidden cameras being increasingly used to snoop on individuals in hotel rooms and Airbnbs, the goal is to be able to pinpoint such rogue devices without much of a hassle.

A fresh look at the Fronton DDoS-focused botnet reveals the criminal tool has more capabilities than previously known. The Fronton botnet first made the headline in March 2020.

"This system includes a web-based dashboard known as SANA that enables a user to formulate and deploy trending social media events en masse. The system creates these events that it refers to as Инфоповоды, 'newsbreaks,' utilizing the botnet as a geographically distributed transport." The existence of Fronton, an IoT botnet, became public knowledge following revelations from BBC Russia and ZDNet in March 2020 after a Russian hacker group known as Digital Revolution published documents that it claimed were obtained after breaking into a subcontractor to the FSB, the Federal Security Service of the Russian Federation.

An unpatched Domain Name System bug in a popular standard C library can allow attackers to mount DNS poisoning attacks against millions of IoT devices and routers to potentially take control of them, researchers have found. "The flaw is caused by the predictability of transaction IDs included in the DNS requests generated by the library, which may allow attackers to perform DNS poisoning attacks against the target device," Nozomi's Giannis Tsaraias and Andrea Palanca wrote in the post.

Cybersecurity researchers have disclosed an unpatched security vulnerability that could pose a serious risk to IoT products. The issue, which was originally reported in September 2021, affects the Domain Name System implementation of two popular C libraries called uClibc and uClibc-ng that are used for developing embedded Linux systems.

A new Mirai-based botnet malware named Enemybot has been observed growing its army of infected devices through vulnerabilities in modems, routers, and IoT devices, with the threat actor operating it known as Keksec. The particular threat group specializes in crypto-mining and DDoS; both supported by botnet malware that can nest in IoT devices and hijack their computational resources.

SentinelOne this week detailed a handful of bugs, including two critical remote code execution vulnerabilities, it found in Microsoft Azure Defender for IoT. These security flaws, which took six months to address, could have been exploited by an unauthenticated attacker to compromise devices and take over critical infrastructure networks. Microsoft Azure Defender for IoT is supposed to detect and respond to suspicious behavior as well as highlight known vulnerabilities, and manage patching and equipment inventories, for Internet-of-Things and industrial control systems.

Nearly half of businesses do not protect their full IoT suite. New research from Kaspersky indicates that 43% of businesses don't protect their full IoT business suite, leaving them vulnerable to cybersecurity breaches and data compromises.
