The Iranian threat actor known as MuddyWater is continuing its time-tested tradition of relying on legitimate remote administration tools to commandeer targeted systems. While the nation-state group has previously employed  ScreenConnect, RemoteUtilities, and Syncro , a  new analysis  from Group-IB has revealed the adversary's use of the SimpleHelp remote support software in June 2022. MuddyWater, active since at least 2017, is assessed to be a subordinate element within Iran's Ministry of Intelligence and Security (MOIS). Some of the top targets include Turkey, Pakistan, the U.A.E., Iraq, Israel, Saudi Arabia, Jordan, the U.S., Azerbaijan, and Afghanistan. "MuddyWater uses SimpleHelp, a legitimate remote device control and management tool, to ensure persistence on victim devices," Nikita Rostovtsev, senior threat analyst at Group-IB, said.

Cybersecurity researchers have found critical security flaws in two popular industrial remote access systems that can be exploited to ban access to industrial production floors, hack into company networks, tamper with data, and even steal sensitive business secrets. The flaws,  discovered  by Tel Aviv-based OTORIO, were identified in B&R Automation's SiteManager and GateManager, and MB Connect Line's mbCONNECT24, two of the popular remote maintenance tools used in automotive, energy, oil & gas, metal, and packaging sectors to connect to industrial assets from anywhere across the world. Six Flaws in B&R Automation's SiteManager and GateManager According to an  advisory published by the US Cybersecurity and infrastructure Security Agency (CISA) on Wednesday, successful exploitation of the B&R Automation vulnerabilities could allow for "arbitrary information disclosure, manipulation, and a denial-of-service condition." The flaws, ranging from p...
