Critical Security Flaws Uncovered in Honeywell Experion DCS and QuickBlox Services

Critical Security Flaws Uncovered in Honeywell Experion DCS and QuickBlox Services

Jul 14, 2023 Vulnerability/ Cyber Threat
Multiple security vulnerabilities have been discovered in various services, including Honeywell Experion distributed control system (DCS) and QuickBlox, that, if successfully exploited, could result in severe compromise of affected systems. Dubbed Crit.IX, the nine flaws in the Honeywell Experion DCS platform allow for "unauthorized remote code execution, which means an attacker would have the power to take over the devices and alter the operation of the DCS controller, whilst also hiding the alterations from the engineering workstation that manages the controller," Armis said in a statement shared with The Hacker News. Put differently, the issues relate to lack of encryption and adequate authentication mechanisms in a proprietary protocol called Control Data Access (CDA) that's used to communicate between Experion Servers and C300 controllers, effectively enabling a threat actor to take over the devices and alter the operation of the DCS controller. "As a resul

Multiple Critical Flaws Discovered in Honeywell Experion PKS and ACE Controllers

Oct 06, 2021
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday  released  an advisory regarding multiple security vulnerabilities affecting all versions of Honeywell Experion Process Knowledge System C200, C200E, C300, and ACE controllers that could be exploited to achieve remote code execution and denial-of-service (DoS) conditions. "A Control Component Library (CCL) may be modified by a bad actor and loaded to a controller such that malicious code is executed by the controller," Honeywell  noted  in an independent security notification published earlier this February. Credited with discovering and reporting the flaws are Rei Henigman and Nadav Erez of industrial cybersecurity firm Claroty. Experion Process Knowledge System (PKS) is a distributed control system ( DCS ) that's designed to control large industrial processes spanning a variety of sectors ranging from petrochemical refineries to nuclear power plants where high reliability and security is imp

How Nation-State Actors Target Your Business: New Research Exposes Major SaaS Vulnerabilities

Feb 15, 2024SaaS Security / Risk Management
With many of the highly publicized 2023 cyber attacks revolving around one or more SaaS applications, SaaS has become a cause for genuine concern in many boardroom discussions. More so than ever, considering that GenAI applications are, in fact, SaaS applications. Wing Security (Wing), a SaaS security company, conducted an analysis of 493 SaaS-using companies in Q4 of 2023.  Their study reveals  how companies use SaaS today, and the wide variety of threats that result from that usage. This unique analysis provides rare and important insights into the breadth and depth of SaaS-related risks, but also provides practical tips to mitigate them and ensure SaaS can be widely used without compromising security posture.  The TL;DR Version Of SaaS Security 2023 brought some now infamous examples of malicious players leveraging or directly targeting SaaS, including the North Korean group UNC4899, 0ktapus ransomware group, and Russian Midnight Blizzard APT, which targeted well-known organizat
