High-Severity Flaws in ConnectedIO's 3G/4G Routers Raise Concerns for IoT Security

High-Severity Flaws in ConnectedIO's 3G/4G Routers Raise Concerns for IoT Security

Oct 09, 2023 Vulnerability / IoT Security
Multiple high-severity security vulnerabilities have been disclosed in ConnectedIO's ER2000 edge routers and the cloud-based management platform that could be exploited by malicious actors to execute malicious code and access sensitive data. "An attacker could have leveraged these flaws to fully compromise the cloud infrastructure, remotely execute code, and leak all customer and device information," Claroty's Noam Moshe  said  in an analysis published last week. Vulnerabilities in 3G/4G routers could expose thousands of internal networks to severe threats, enabling bad actors to seize control, intercept traffic, and even infiltrate Extended Internet of Things (XIoT) things. The shortcomings impacting the ConnectedIO platform versions v2.1.0 and prior, primarily the 4G ER2000 edge router and cloud services, could be chained, permitting attackers to execute arbitrary code on the cloud-based devices without requiring direct access to them. Flaws have also been unea

Sep 15, 2023 IoT Security / Cyber Threat
The  Internet of Things (IoT)  is transforming efficiency in various sectors like healthcare and logistics but has also introduced new security risks, particularly IoT-driven DDoS attacks. This article explores how these attacks work, why they're uniquely problematic, and how to mitigate them. What Is IoT? IoT (Internet of Things) refers to online, interconnected devices that collect and exchange data. This broad category of devices includes sensors, cameras, network routers, and advanced machinery, and their integration into everyday life and work processes results in an ecosystem that can automate operations, improve decision-making, and enhance user experience. IoT: A Breeding Ground for Botnets IoT's rapid adoption amplifies its vulnerability, as poorly secured devices become easy prey for attackers and may become part of a botnet. Controlled by attackers, botnets can scale and rapidly execute various attacks, including DDoS, data theft, ad fraud, cryptocurrency mining, spam a

The Secret Weakness Execs Are Overlooking: Non-Human Identities

Oct 03, 2024Enterprise Security / Cloud Security
For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

New Flaws in TPM 2.0 Library Pose Threat to Billions of IoT and Enterprise Devices

Mar 03, 2023 Enterprise Security / IoT
A pair of serious security defects has been disclosed in the Trusted Platform Module ( TPM ) 2.0 reference library specification that could potentially lead to information disclosure or privilege escalation. One of the vulnerabilities,  CVE-2023-1017 , concerns an out-of-bounds write, while the other,  CVE-2023-1018 , is described as an out-of-bounds read. Credited with discovering and reporting the issues in November 2022 is cybersecurity company Quarkslab. "These vulnerabilities can be triggered from user-mode applications by sending malicious commands to a TPM 2.0 whose firmware is based on an affected TCG reference implementation," the Trusted Computing Group (TCG)  said  in an advisory. Large tech vendors, organizations using enterprise computers, servers, IoT devices, and embedded systems that include a TPM can be impacted by the flaws, Quarkslab  noted , adding they "could affect billions of devices." TPM is a hardware-based solution (i.e., a crypto-pro

New Mirai Botnet Variant 'V3G4' Exploiting 13 Flaws to Target Linux and IoT Devices

Feb 17, 2023 IoT Security / Cyber Attack
A new variant of the notorious Mirai botnet has been found leveraging several security vulnerabilities to propagate itself to Linux and IoT devices. Observed during the second half of 2022, the new version has been dubbed  V3G4  by Palo Alto Networks Unit 42, which identified three different campaigns likely conducted by the same threat actor. "Once the vulnerable devices are compromised, they will be fully controlled by attackers and become a part of the botnet," Unit 42 researchers  said . "The threat actor has the capability to utilize those devices to conduct further attacks, such as distributed denial-of-service (DDoS) attacks." The attacks primarily single out exposed servers and networking devices running Linux, with the adversary weaponizing as many as 13 flaws that could lead to remote code execution (RCE). Some of the notable flaws relate to critical flaws in Atlassian Confluence Server and Data Center, DrayTek Vigor routers, Airspan AirSpot, and Geu
Critical Infrastructure at Risk from New Vulnerabilities Found in Wireless IIoT Devices

Critical Infrastructure at Risk from New Vulnerabilities Found in Wireless IIoT Devices

Feb 09, 2023 Network Security / IoT Security
A set of 38 security vulnerabilities has been uncovered in wireless industrial internet of things (IIoT) devices from four different vendors that could pose a significant attack surface for threat actors looking to exploit operational technology (OT) environments. "Threat actors can exploit vulnerabilities in Wireless IIoT devices to gain initial access to internal OT networks," Israeli industrial cybersecurity company Otorio  said . "They can use these vulnerabilities to bypass security layers and infiltrate target networks, putting critical infrastructure at risk or interrupting manufacturing." The flaws, in a nutshell, offer a remote entry point for attack, enabling unauthenticated adversaries to gain a foothold and subsequently use it as leverage to spread to other hosts, thereby causing serious damage. Some of the identified shortcomings could be chained to give an external actor direct access to thousands of internal OT networks over the internet, security
Researchers Detail New Attack Method to Bypass Popular Web Application Firewalls

Researchers Detail New Attack Method to Bypass Popular Web Application Firewalls

Dec 10, 2022 Web App Firewall / Web Security
A new attack method can be used to circumvent web application firewalls (WAFs) of various vendors and infiltrate systems, potentially enabling attackers to gain access to sensitive business and customer information. Web application firewalls are a  key line of defense  to help filter, monitor, and block HTTP(S) traffic to and from a web application, and safeguard against attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection (SQLi). The generic bypass "involves appending  JSON syntax  to SQL injection payloads that a WAF is unable to parse," Claroty researcher Noam Moshe  said . "Most WAFs will easily detect SQLi attacks, but prepending JSON to SQL syntax left the WAF blind to these attacks." The industrial and IoT cybersecurity company said its technique successfully worked against WAFs from vendors like Amazon Web Services (AWS), Cloudflare, F5, Imperva, and Palo Alto Networks, all of whom have since released updates

Hackers Exploiting Abandoned Boa Web Servers to Target Critical Industries

Nov 23, 2022
Microsoft on Tuesday disclosed the intrusion activity aimed at Indian power grid entities earlier this year likely involved the exploitation of security flaws in a now-discontinued web server called Boa . The tech behemoth's cybersecurity division  said  the vulnerable component poses a "supply chain risk that may affect millions of organizations and devices." The findings build on a prior report  published  by Recorded Future in April 2022, which delved into a sustained campaign orchestrated by suspected China-linked adversaries to strike critical infrastructure organizations in India. The cybersecurity firm attributed the attacks to a previously undocumented threat cluster called Threat Activity Group 38. While the Indian government described the attacks as unsuccessful "probing attempts," China denied it was behind the campaign. The connections to China stem from the use of a modular backdoor dubbed  ShadowPad , which is known to be shared among several

Jun 21, 2022
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
U.S. Warns of APT Hackers Targeting ICS/SCADA Systems with Specialized Malware

U.S. Warns of APT Hackers Targeting ICS/SCADA Systems with Specialized Malware

Apr 14, 2022
The U.S. government on Wednesday warned of nation-state actors deploying specialized malware to maintain access to industrial control systems (ICS) and supervisory control and data acquisition (SCADA) devices. "The APT actors have developed custom-made tools for targeting ICS/SCADA devices," multiple U.S. agencies  said  in an alert. "The tools enable them to scan for, compromise, and control affected devices once they have established initial access to the operational technology (OT) network." The joint federal advisory comes courtesy of the U.S. Department of Energy (DoE), the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), and the Federal Bureau of Investigation (FBI). The custom-made tools are specifically designed to single out Schneider Electric programmable logic controllers (PLCs), OMRON Sysmac NEX PLCs, and Open Platform Communications Unified Architecture (OPC UA) servers. On top of that, the unnamed actors

IoT/connected Device Discovery and Security Auditing in Corporate Networks

Feb 07, 2022
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
Detecting Evasive Malware on IoT Devices Using Electromagnetic Emanations

Detecting Evasive Malware on IoT Devices Using Electromagnetic Emanations

Jan 03, 2022
Cybersecurity researchers have proposed a novel approach that harnesses electromagnetic field emanations from the Internet of Things (IoT) devices as a side-channel to glean precise knowledge about the different kinds of malware targeting the embedded systems, even in scenarios where obfuscation techniques have been applied to hinder analysis. With the rapid adoption of IoT appliances presenting an attractive attack surface for threat actors, in part due to them being equipped with higher processing power and capable of running fully functional operating systems, the latest research aims to improve malware analysis to mitigate potential security risks. The findings were presented by a group of academics from the Research Institute of Computer Science and Random Systems (IRISA) at the Annual Computer Security Applications Conference ( ACSAC ) held last month. "[Electromagnetic] emanation that is measured from the device is practically undetectable by the malware," the res

Eavesdropping Bugs in MediaTek Chips Affect 37% of All Smartphones and IoT Globally

Nov 24, 2021
Multiple security weaknesses have been disclosed in MediaTek system-on-chips (SoCs) that could have enabled a threat actor to elevate privileges and execute arbitrary code in the firmware of the audio processor, effectively allowing the attackers to carry out a "massive eavesdrop campaign" without the users' knowledge. The discovery of the flaws is the result of reverse-engineering the Taiwanese company's audio digital signal processor ( DSP ) unit by Israeli cybersecurity firm Check Point Research, ultimately finding that by stringing them together with other flaws present in a smartphone manufacturer's libraries, the issues uncovered in the chip could lead to local privilege escalation from an Android application.  "A malformed inter-processor message could potentially be used by an attacker to execute and hide malicious code inside the DSP firmware," Check Point security researcher Slava Makkaveev  said  in a report. "Since the DSP firmware h
A Critical Random Number Generator Flaw Affects Billions of IoT Devices

A Critical Random Number Generator Flaw Affects Billions of IoT Devices

Aug 09, 2021
A critical vulnerability has been disclosed in hardware random number generators used in billions of Internet of Things (IoT) devices whereby it fails to properly generate random numbers, thus undermining their security and putting them at risk of attacks. "It turns out that these 'randomly' chosen numbers aren't always as random as you'd like when it comes to IoT devices," Bishop Fox researchers Dan Petro and Allan Cecil  said  in an analysis published last week. "In fact, in many cases, devices are choosing encryption keys of 0 or worse. This can lead to a catastrophic collapse of security for any upstream use." Random number generation ( RNG ) is a  crucial process  that undergirds several cryptographic applications, including key generation, nonces, and salting. On traditional operating systems, it's derived from a cryptographically secure pseudorandom number generator (CSPRNG) that uses entropy obtained from a high-quality seed source.
