Critical Bugs Could Let Attackers Remotely Hack, Damage APC Smart-UPS Devices

Critical Bugs Could Let Attackers Remotely Hack, Damage APC Smart-UPS Devices

March 09, 2022Ravie Lakshmanan
Three high-impact security vulnerabilities have been disclosed in  APC Smart-UPS devices  that could be abused by remote adversaries as a physical weapon to access and control them in an unauthorized manner. Collectively dubbed  TLStorm , the flaws "allow for complete remote takeover of Smart-UPS devices and the ability to carry out extreme cyber-physical attacks," Ben Seri and Barak Hadad, researchers from IoT security company Armis, said in a report published Tuesday. Uninterruptible power supply ( UPS ) devices function as emergency backup power providers in mission-critical environments such as medical facilities, server rooms, and industrial systems. Most of the afflicted devices, totaling over 20 million, have been identified so far in healthcare, retail, industrial, and government sectors. TLStorm consists of a trio of critical flaws that can be triggered via unauthenticated network packets without requiring any user interaction, meaning it's a zero-click att

IoT/connected Device Discovery and Security Auditing in Corporate Networks

Today's enterprise networks are complex environments with different types of wired and wireless devices being connected and disconnected. The current device discovery solutions have been mainly focused on identifying and monitoring servers, workstation PCs, laptops and infrastructure devices such as network firewalls, switches and routers, because the most valuable information assets of organizations are being stored, processed and transferred over those devices, hence making them the prime target of security breaches and intrusions. However, a new trend has been emerging in the past four years,  where attackers have been targeting purpose-built connected devices  such as network printers and video conferencing systems as an entry point and data exfiltration route. These devices cannot be identified properly by the current IT asset discovery solutions for the following main reasons: Proprietary protocols are often used for managing and monitoring such devices that are not know
New iLOBleed Rootkit Targeting HP Enterprise Servers with Data Wiping Attacks

New iLOBleed Rootkit Targeting HP Enterprise Servers with Data Wiping Attacks

A previously unknown rootkit has been found setting its sights on Hewlett-Packard Enterprise's Integrated Lights-Out ( iLO ) server management technology to carry out in-the-wild attacks that tamper with the firmware modules and completely wipe data off the infected systems. The discovery, which is the first instance of real-world malware in iLO firmware, was documented by Iranian cybersecurity firm Amnpardaz this week. "There are numerous aspects of iLO that make it an ideal utopia for malware and APT groups: Extremely high privileges (above any level of access in the operating system), very low-level access to the hardware, being totally out of the sight of the admins, and security tools, the general lack of knowledge and tools for inspecting iLO and/or protecting it, the persistence it provides for the malware to remain even after changing the operating system, and in particular being always running and never shutting down," the researchers  said .
