The cyber attacks targeting the energy sector in Denmark last year may not have had the involvement of the Russia-linked Sandworm hacking group,  new findings  from Forescout show. The intrusions, which  targeted around 22 Danish energy organizations  in May 2023, occurred in two distinct waves, one which exploited a security flaw in Zyxel firewall (CVE-2023-28771) and a follow-on activity cluster that saw the attackers deploy Mirai botnet variants on infected hosts via an as-yet-unknown initial access vector. The first wave took place on May 11, while the second wave lasted from May 22 to 31, 2023. In one such attack detected on May 24, it was observed that the compromised system was communicating with IP addresses (217.57.80[.]18 and 70.62.153[.]174) that were previously used as command-and-control (C2) for the now-dismantled  Cyclops Blink  botnet. Forescout's closer examination of the attack campaign, however, has revealed that not only were the two waves unrelated, but also

A collection of 21 security flaws have been discovered in Sierra Wireless AirLink cellular routers and open-source software components like  TinyXML  and  OpenNDS . Collectively tracked as  Sierra:21 , the issues expose over 86,000 devices across critical sectors like energy, healthcare, waste management, retail, emergency services, and vehicle tracking to cyber threats, according to Forescout Vedere Labs. A majority of these devices are located in the U.S., Canada, Australia, France, and Thailand. "These vulnerabilities may allow attackers to steal credentials, take control of a router by injecting malicious code, persist on the device and use it as an initial access point into critical networks," the industrial cybersecurity company  said  in a new analysis. Of the 21 vulnerabilities, one is rated critical, nine are rated high, and 11 are rated medium in severity. This includes remote code execution (RCE), cross-site scripting (XSS), denial-of-service (DoS), unauthori

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

Nearly five dozen security vulnerabilities have been disclosed in devices from 10 operational technology (OT) vendors due to what researchers call are "insecure-by-design practices." Collectively dubbed  OT:ICEFALL  by Forescout, the 56 issues span as many as 26 device models from Bently Nevada, Emerson, Honeywell, JTEKT, Motorola, Omron, Phoenix Contact, Siemens, and Yokogawa. "Exploiting these vulnerabilities, attackers with network access to a target device could remotely execute code, change the logic, files or firmware of OT devices, bypass authentication, compromise credentials, cause denials of service or have a variety of operational impacts," the company said in a technical report. These vulnerabilities could have disastrous consequences considering the impacted products are widely employed in critical infrastructure industries such as oil and gas, chemical, nuclear, power generation and distribution, manufacturing, water treatment and distribution, min
