A critical security flaw has been disclosed in the Microchip Advanced Software Framework (ASF) that, if successfully exploited, could lead to remote code execution. The vulnerability, tracked as CVE-2024-7490 , carries a CVSS score of 9.5 out of a maximum of 10.0. It has been described as a stack-based overflow vulnerability in ASF's implementation of the tinydhcp server stemming from a lack of adequate input validation. "There exists a vulnerability in all publicly available examples of the ASF codebase that allows for a specially crafted DHCP request to cause a stack-based overflow that could lead to remote code execution," CERT Coordination Center (CERT/CC) said in an advisory. Given that the software is no longer supported and is rooted in IoT-centric code, CERT/CC has warned that the vulnerability is "likely to surface in many places in the wild." The issue impacts ASF 3.52.0.2574 and all prior versions of the software, with the agency also noting th

Cybersecurity researchers have uncovered a never-before-seen botnet comprising an army of small office/home office (SOHO) and IoT devices that are likely operated by a Chinese nation-state threat actor called Flax Typhoon (aka Ethereal Panda or RedJuliett). The sophisticated botnet, dubbed Raptor Train by Lumen's Black Lotus Labs, is believed to have been operational since at least May 2020, hitting a peak of 60,000 actively compromised devices in June 2023. "Since that time, there have been more than 200,000 SOHO routers, NVR/DVR devices, network attached storage (NAS) servers, and IP cameras; all conscripted into the Raptor Train botnet, making it one of the largest Chinese state-sponsored IoT botnets discovered to-date," the cybersecurity company said in a 81-page report shared with The Hacker News. The infrastructure powering the botnet is estimated to have ensnared hundreds of thousands of devices since its formation, with the network powered by a three-tiered

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,

Nearly 1.3 million Android-based TV boxes running outdated versions of the operating system and belonging to users spanning 197 countries have been infected by a new malware dubbed Vo1d (aka Void). "It is a backdoor that puts its components in the system storage area and, when commanded by attackers, is capable of secretly downloading and installing third-party software," Russian antivirus vendor Doctor Web said in a report published today. A majority of the infections have been detected in Brazil, Morocco, Pakistan, Saudi Arabia, Argentina, Russia, Tunisia, Ecuador, Malaysia, Algeria, and Indonesia. It's currently not known what the source of the infection is, although it's suspected that it may have either involved an instance of prior compromise that allows for gaining root privileges or the use of unofficial firmware versions with built-in root access. The following TV models have been targeted as part of the campaign - KJ-SMART4KVIP (Android 10.1; KJ-SMA

A years-old high-severity flaw impacting AVTECH IP cameras has been weaponized by malicious actors as a zero-day to rope them into a botnet. CVE-2024-7029 (CVSS score: 8.7), the vulnerability in question, is a "command injection vulnerability found in the brightness function of AVTECH closed-circuit television (CCTV) cameras that allows for remote code execution (RCE)," Akamai researchers Kyle Lefton, Larry Cashdollar, and Aline Eliovich said . Details of the security shortcoming were first made public earlier this month by the U.S. Cybersecurity and Infrastructure Security Agency (CISA), highlighting its low attack complexity and the ability to exploit it remotely. "Successful exploitation of this vulnerability could allow an attacker to inject and execute commands as the owner of the running process," the agency noted in an alert published August 1, 2024. It's worth noting that the issue remains unpatched. It impacts AVM1203 camera devices using firmwar

Cybersecurity researchers have discovered a new variant of the Gafgyt botnet that's targeting machines with weak SSH passwords to ultimately mine cryptocurrency on compromised instances using their GPU computational power. This indicates that the "IoT botnet is targeting more robust servers running on cloud native environments," Aqua Security researcher Assaf Morag said in a Wednesday analysis. Gafgyt (aka BASHLITE, Lizkebab, and Torlus), known to be active in the wild since 2014, has a history of exploiting weak or default credentials to gain control of devices such as routers, cameras, and digital video recorders (DVRs). It's also capable of leveraging known security flaws in Dasan, Huawei, Realtek, SonicWall, and Zyxel devices. The infected devices are corralled into a botnet capable of launching distributed denial-of-service (DDoS) attacks against targets of interest. There is evidence to suggest that Gafgyt and Necro are operated by a threat group calle

Cybersecurity researchers have identified a number of security shortcomings in photovoltaic system management platforms operated by Chinese companies Solarman and Deye that could enable malicious actors to cause disruption and power blackouts. "If exploited, these vulnerabilities could allow an attacker to control inverter settings that could take parts of the grid down, potentially causing blackouts," Bitdefender researchers said in an analysis published last week. The vulnerabilities have been addressed by Solarman and Deye as of July 2024, following responsible disclosure on May 22, 2024. The Romanian cybersecurity vendor, which analyzed the two PV monitoring and management platforms, said they suffer from a number of issues that, among others, could result in account takeover and information disclosure. A brief description of the issues is listed below - Full Account Takeover via Authorization Token Manipulation Using the /oauth2-s/oauth/token API endpoint  Deye

Security vulnerabilities have been disclosed in the industrial remote access solution Ewon Cosy+ that could be abused to gain root privileges to the devices and stage follow-on attacks. The elevated access could then be weaponized to decrypt encrypted firmware files and encrypted data such as passwords in configuration files, and even get correctly signed X.509 VPN certificates for foreign devices to take over their VPN sessions. "This allows attackers hijacking VPN sessions which results in significant security risks against users of the Cosy+ and the adjacent industrial infrastructure," SySS GmbH security researcher Moritz Abrell said in a new analysis. The findings were presented at the DEF CON 32 conference over the weekend. Following responsible disclosure, the issues have been addressed in firmware versions 21.2s10 and 22.1s3 as part of an advisory [PDF] issued by Ewon on July 29, 2024 - CVE-2024-33892 (CVSS score: 7.4) - Information leakage through cookies

Cybersecurity researchers have uncovered weaknesses in Sonos smart speakers that could be exploited by malicious actors to clandestinely eavesdrop on users. The vulnerabilities "led to an entire break in the security of Sonos's secure boot process across a wide range of devices and remotely being able to compromise several devices over the air," NCC Group security researchers Alex Plaskett and Robert Herrera said . Successful exploitation of one of these flaws could allow a remote attacker to obtain covert audio capture from Sonos devices by means of an over-the-air attack. They impact all versions prior to Sonos S2 release 15.9 and Sonos S1 release 11.12, which were shipped in October and November 2023. The findings were presented at Black Hat USA 2024. A description of the two security defects is as follows - CVE-2023-50809 - A vulnerability in the Sonos One Gen 2 Wi-Fi stack that does not properly validate an information element while negotiating a WPA2 four-wa

The Problem The "2024 Attack Intelligence Report" from the staff at Rapid7 [1] is a well-researched, well-written report that is worthy of careful study. Some key takeaways are:  53% of the over 30 new vulnerabilities that were widely exploited in 2023 and at the start of 2024 were zero-days . More mass compromise events arose from zero-day vulnerabilities than from n-day vulnerabilities. Nearly a quarter of widespread attacks were zero-day attacks where a single adversary compromised dozens to hundreds of organizations simultaneously. Attackers are moving from initial access to exploitation in minutes or hours rather than days or weeks. So the conventional patch and put strategy is as effective as a firetruck showing up after a building has burned to the ground! Of course, patch and put could prevent future attacks, but taking into account that patch development takes from days to weeks [2] and that the average time to apply critical patches is 16 days [3], devices are vulner

Apple has released a firmware update for AirPods that could allow a malicious actor to gain access to the headphones in an unauthorized manner. Tracked as CVE-2024-27867, the authentication issue affects AirPods (2nd generation and later), AirPods Pro (all models), AirPods Max, Powerbeats Pro, and Beats Fit Pro. "When your headphones are seeking a connection request to one of your previously paired devices, an attacker in Bluetooth range might be able to spoof the intended source device and gain access to your headphones," Apple said in a Tuesday advisory. In other words, an adversary in physical proximity could exploit the vulnerability to eavesdrop on private conversations. Apple said the issue has been addressed with improved state management. Jonas Dreßler has been credited with discovering and reporting the flaw. It has been patched as part of AirPods Firmware Update 6A326, AirPods Firmware Update 6F8, and Beats Firmware Update 6F8. The development comes two week

Cybersecurity researchers have disclosed multiple security flaws in Cinterion cellular modems that could be potentially exploited by threat actors to access sensitive information and achieve code execution. "These vulnerabilities include critical flaws that permit remote code execution and unauthorized privilege escalation, posing substantial risks to integral communication networks and IoT devices foundational to industrial, healthcare, automotive, financial and telecommunications sectors," Kaspersky  said . Cinterion modems were originally developed by Gemalto before the business was  acquired  by Telit from Thales as part of a deal announced in July 2022. The findings were  presented  at the OffensiveCon held in Berlin on May 11. The list of eight flaws is as follows - CVE-2023-47610  (CVSS score: 8.1) - A buffer overflow vulnerability that could allow a remote unauthenticated attacker to execute arbitrary code on the targeted system by sending a specially crafted S

The U.K. National Cyber Security Centre (NCSC) is calling on manufacturers of smart devices to comply with new legislation that prohibits them from using default passwords, effective April 29, 2024. "The law, known as the  Product Security and Telecommunications Infrastructure act  (or PSTI act), will help consumers to choose smart devices that have been designed to provide ongoing protection against cyber attacks," the NCSC  said . To that end, manufacturers are required to not supply devices that use guessable default passwords, provide a point of contact to report security issues, and state the duration for which their devices are expected to receive important security updates. Default passwords can not only be easily found online, they also act as a vector for threat actors to log in to devices for follow-on exploitation. That said, a unique default password is permissible under the law. The law, which aims to enforce a set of minimum security standards across the b

Cisco is warning about a global surge in brute-force attacks targeting various devices, including Virtual Private Network (VPN) services, web application authentication interfaces, and SSH services, since at least March 18, 2024. "These attacks all appear to be originating from TOR exit nodes and a range of other anonymizing tunnels and proxies," Cisco Talos  said . Successful attacks could pave the way for unauthorized network access, account lockouts, or denial-of-service conditions, the cybersecurity company added. The attacks, said to be broad and opportunistic, have been observed targeting the below devices - Cisco Secure Firewall VPN  Check Point VPN Fortinet VPN SonicWall VPN RD Web Services  MikroTik  Draytek  Ubiquiti  Cisco Talos described the brute-forcing attempts as using both generic and valid usernames for specific organizations, with the attacks indiscriminately targeting a wide range of sectors across geographies. The source IP addresses for

A botnet previously considered to be rendered inert has been observed enslaving end-of-life (EoL) small home/small office (SOHO) routers and IoT devices to fuel a criminal proxy service called Faceless. " TheMoon , which  emerged  in  2014 , has been operating quietly while growing to over 40,000 bots from 88 countries in January and February of 2024," the Black Lotus Labs team at Lumen Technologies  said . Faceless,  detailed  by security journalist Brian Krebs in April 2023, is a malicious residential proxy service that's offered its anonymity services to other threat actors for a negligible fee that costs less than a dollar per day. In doing so, it allows the customers to route their malicious traffic through tens of thousands of compromised systems advertised on the service, effectively concealing their true origins. The Faceless-backed infrastructure has been assessed to be used by operators of malware such as  SolarMarker  and  IcedID  to connect to their comm

Due to the rapid evolution of technology, the Internet of Things (IoT) is changing the way business is conducted around the world. This advancement and the power of the IoT have been nothing short of transformational in making data-driven decisions, accelerating efficiencies, and streamlining operations to meet the demands of a competitive global marketplace. IoT At a Crossroads IoT, in its most basic terms, is the intersection of the physical and digital world with distinct applications and purposes. It is devices, sensors, and systems of all kinds harnessing the power of interconnectivity through the internet to provide seamless experiences for business. Up until today, we, as security professionals, have been very good at writing about the numerous and varying IoT applications and uses and have agreed upon the fact that the security of the IoT is important. However, have we really understood the big picture? And that is for IoT to really reach its full potential as a fully inter
