Considerations for Operational Technology Cybersecurity

Apr 30, 2024 Operational Technology / Cybersecurity
Operational Technology (OT)  refers to the hardware and software used to change, monitor, or control the enterprise's physical devices, processes, and events. Unlike traditional Information Technology (IT) systems, OT systems directly impact the physical world. This unique characteristic of OT brings additional cybersecurity considerations not typically present in conventional IT security architectures. The convergence of IT and OT Historically, IT and Operational Technology (OT) have operated in separate silos, each with its own set of protocols, standards, and cybersecurity measures. However, these two domains are increasingly converging with the advent of the Industrial Internet of Things (IIoT). While beneficial in terms of increased efficiency and data-driven decision-making, this convergence also exposes OT systems to the same cyber threats that IT systems face. Unique Cybersecurity Considerations for OT Real-time requirements Operational Technology systems often opera

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

SHQ Response Platform and Risk Centre to Enable Management and Analysts Alike

May 13, 2024Threat Detection / SoC / SIEM
In the last decade, there has been a growing disconnect between front-line analysts and senior management in IT and Cybersecurity. Well-documented challenges facing modern analysts revolve around a high volume of alerts, false positives, poor visibility of technical environments, and analysts spending too much time on manual tasks. The Impact of Alert Fatigue and False Positives  Analysts are overwhelmed with alerts. The knock-on effect of this is that fatigued analysts are at risk of missing key details in incidents, and often conduct time-consuming triaging tasks manually only to end up copying and pasting a generic closing comment into a false positive alert.  It is likely that there will always be false positives. And many would argue that a false positive is better than a false negative. But for proactive actions to be made, we must move closer to the heart of an incident. That requires diving into how analysts conduct the triage and investigation process. SHQ Response Platfo

Getting off the Attack Surface Hamster Wheel: Identity Can Help

Getting off the Attack Surface Hamster Wheel: Identity Can Help

Jan 10, 2024 Attack Surface / Cybersecurity
IT professionals have developed a sophisticated understanding of the enterprise attack surface – what it is, how to quantify it and how to manage it.  The process is simple: begin by thoroughly assessing the attack surface, encompassing the entire IT environment. Identify all potential entry and exit points where unauthorized access could occur. Strengthen these vulnerable points using available market tools and expertise to achieve the desired cybersecurity posture.  While conceptually straightforward, this is an incredibly tedious task that consumes the working hours of CISOs and their organizations. Both the enumeration and the fortification pose challenges: large organizations use a vast array of technologies, such as server and endpoint platforms, network devices, and business apps. Reinforcing each of these components becomes a frustrating exercise in integration with access control, logging, patching, monitoring, and more, creating a seemingly endless list of tasks.  However
New NKAbuse Malware Exploits NKN Blockchain Tech for DDoS Attacks

New NKAbuse Malware Exploits NKN Blockchain Tech for DDoS Attacks

Dec 15, 2023 Blockchain / Internet of Things
A novel multi-platform threat called  NKAbuse  has been discovered using a decentralized, peer-to-peer network connectivity protocol known as  NKN  (short for New Kind of Network) as a communications channel. "The malware utilizes NKN technology for data exchange between peers, functioning as a potent implant, and equipped with both flooder and backdoor capabilities," Russian cybersecurity company Kaspersky  said  in a Thursday report. NKN, which has over 62,000 nodes, is  described  as a "software overlay network built on top of today's Internet that enables users to share unused bandwidth and earn token rewards." It incorporates a blockchain layer on top of the existing TCP/IP stack. While threat actors are known to take advantage of emerging communication protocols for command-and-control (C2) purposes and evade detection, NKAbuse leverages blockchain technology to conduct distributed denial-of-service (DDoS) attacks and function as an implant inside com

KmsdBot Malware Gets an Upgrade: Now Targets IoT Devices with Enhanced Capabilities

Aug 28, 2023 Internet of Things / Malware
An updated version of a botnet malware called  KmsdBot  is now targeting Internet of Things (IoT) devices, simultaneously branching out its capabilities and the attack surface. "The binary now includes support for  Telnet scanning  and support for more CPU architectures," Akamai security researcher Larry W. Cashdollar  said  in an analysis published this month. The latest iteration, observed since July 16, 2023, comes months after it emerged that the botnet is being offered as a  DDoS-for-hire service  to other threat actors. The fact that it's being actively maintained indicates its effectiveness in real-world attacks. KmsdBot was  first documented  by the web infrastructure and security company in November 2022. It's mainly employed to target private gaming servers and cloud hosting providers, although it has since set its eyes on some Romanian government and Spanish educational sites. The malware is designed to scan random IP addresses for open SSH ports and
New Cryptocurrency Mining Campaign Targets Linux Systems and IoT Devices

New Cryptocurrency Mining Campaign Targets Linux Systems and IoT Devices

Jun 23, 2023 Cryptocurrency / IoT
Internet-facing Linux systems and Internet of Things (IoT) devices are being targeted as part of a new campaign designed to illicitly mine cryptocurrency. "The threat actors behind the attack use a backdoor that deploys a wide array of tools and components such as rootkits and an IRC bot to steal device resources for mining operations," Microsoft threat intelligence researcher Rotem Sde-Or  said . "The backdoor also installs a patched version of OpenSSH on affected devices, allowing threat actors to hijack SSH credentials, move laterally within the network, and conceal malicious SSH connections." To pull off the scheme, misconfigured Linux hosts are brute-forced to gain initial access, following which the threat actors move to disable shell history and fetch a trojanized version of OpenSSH from a remote server. The rogue OpenSSH package is configured to install and launch the backdoor, a shell script that allows the attackers to distribute additional payloads a

3 New Vulnerabilities Affect OT Products from German Companies Festo and CODESYS

Nov 30, 2022
Researchers have disclosed details of three new security vulnerabilities affecting operational technology (OT) products from CODESYS and Festo that could lead to source code tampering and denial-of-service (DoS). The vulnerabilities, reported by Forescout Vedere Labs, are the latest in a long list of flaws collectively tracked under the name  OT:ICEFALL . "These issues exemplify either an insecure-by-design approach — which was usual at the time the products were launched – where manufacturers include dangerous functions that can be accessed with no authentication or a subpar implementation of security controls, such as cryptography," the researchers  said . The most critical of the flaws is  CVE-2022-3270  (CVSS score: 9.8), a critical vulnerability that affects Festo automation controllers using the Festo Generic Multicast (FGMC) protocol to reboot the devices without requiring any authentication and cause a denial of service (DoS) condition.

Lumos System Can Find Hidden Cameras and IoT Devices in Your Airbnb or Hotel Room

Lumos System Can Find Hidden Cameras and IoT Devices in Your Airbnb or Hotel Room

May 25, 2022
A group of academics has devised a system that can be used on a phone or a laptop to identify and locate Wi-Fi-connected hidden IoT devices in unfamiliar physical spaces. With hidden cameras being  increasingly   used  to  snoop  on  individuals  in hotel rooms and Airbnbs, the goal is to be able to pinpoint such rogue devices without much of a hassle. The system, dubbed Lumos , is designed with this intent in mind and to "visualize their presence using an augmented reality interface,"  said  Rahul Anand Sharma, Elahe Soltanaghaei, Anthony Rowe, and Vyas Sekar of Carnegie Mellon University in a new paper. At its core, the platform works by snuffing and collecting encrypted wireless packets over the air to detect and identify concealed devices. Subsequently, it estimates the location of each identified device with respect to the user as they walk around the perimeter of the space. The localization module, for its part, combines signal strength measurements that are avail

New Hacker Group Pursuing Corporate Employees Focused on Mergers and Acquisitions

May 03, 2022
A newly discovered suspected espionage threat actor has been targeting employees focusing on mergers and acquisitions as well as large corporate transactions to facilitate bulk email collection from victim environments. Mandiant is tracking the activity cluster under the uncategorized moniker UNC3524, citing a lack of evidence linking it to an existing group. However, some of the intrusions are said to mirror techniques used by different Russia-based hacking crews like  APT28  and  APT29 .  "The high level of operational security, low malware footprint, adept evasive skills, and a large Internet of Things (IoT) device botnet set this group apart and emphasize the 'advanced' in Advanced Persistent Threat," the threat intelligence firm  said  in a Monday report. The initial access route is unknown but upon gaining a foothold, attack chains involving UNC3524 culminate in the deployment of a novel backdoor called QUIETEXIT for persistent remote access for as long as

Bugs in Wyze Cams Could Let Attackers Takeover Devices and Access Video Feeds

Mar 31, 2022
Three security vulnerabilities have been disclosed in the popular Wyze Cam devices that grant malicious actors to execute arbitrary code and access camera feeds as well as unauthorizedly read the SD cards, the latter of which remained unresolved for nearly three years after the initial discovery. The security flaws relate to an authentication bypass (CVE-2019-9564), a remote code execution bug stemming from a stack-based buffer overflow (CVE-2019-12266), and a case of unauthenticated access to the contents of the SD card (no CVE). Successful exploitation of the bypass vulnerability could allow an outside attacker to fully control the device, including disabling recording to the SD card and turning on/off the camera, not to mention chaining it with CVE-2019-12266 to view the live audio and video feeds. Romanian cybersecurity firm Bitdefender, which  discovered the shortcomings , said it reached out to the vendor way back in May 2019, following which Wyze released patches to fix CVE

TrickBot Malware Abusing MikroTik Routers as Proxies for Command-and-Control

Mar 17, 2022
Microsoft on Wednesday detailed a previously undiscovered technique put to use by the TrickBot malware that involves using compromised Internet of Things (IoT) devices as a go-between for establishing communications with the command-and-control (C2) servers. "By using MikroTik routers as proxy servers for its C2 servers and redirecting the traffic through non-standard ports, TrickBot adds another persistence layer that helps malicious IPs evade detection by standard security systems," Microsoft's Defender for IoT Research Team and Threat Intelligence Center (MSTIC)  said . TrickBot, which emerged as a banking trojan in 2016, has evolved into a sophisticated and persistent threat, with its modular architecture enabling it to adapt its tactics to suit different networks, environments, and devices as well as offer access-as-a-service for next-stage payloads like Conti ransomware. The expansion to TrickBot's capabilities comes amid reports of its  infrastructure goin
