Threat actors are capitalizing on the growing popularity of proxyware platforms like Honeygain and Nanowire to monetize their own malware campaigns, once again illustrating how attackers are quick to  repurpose and weaponize legitimate platforms  to their advantage. "Malware is currently leveraging these platforms to monetize the internet bandwidth of victims, similar to how malicious cryptocurrency mining attempts to monetize the CPU cycles of infected systems," researchers from Cisco Talos  said  in a Tuesday analysis. "In many cases, these applications are featured in multi-stage, multi-payload malware attacks that provide adversaries with multiple monetization methods." Proxyware, also called internet-sharing applications, are legitimate services that allow users to carve out a percentage of their internet bandwidth for other devices, often for a fee, through a client application offered by the provider, enabling other customers to access the internet using ...

Cybersecurity researchers on Tuesday disclosed details about a zero-click security vulnerability in the Linphone Session Initiation Protocol ( SIP ) stack that could be remotely exploited without any action from a victim to crash the SIP client and cause a denial-of-service (DoS) condition. Tracked as  CVE-2021-33056  (CVSS score: 7.5), the issue concerns a NULL pointer dereference vulnerability in the " belle-sip " component, a C-language library used to implement SIP transport, transaction, and dialog layers, with all versions prior to  4.5.20  affected by the flaw. The weakness was discovered and reported by industrial cybersecurity company Claroty. Linphone is an open-source and cross-platform SIP client with support for voice and video calls, end-to-end encrypted messaging, and audio conference calls, among others. SIP, on the other hand, is a signaling protocol used for initiating, maintaining, and terminating real-time multimedia communication sessions for...

Cybersecurity could be described as a marathon for security teams that spend most of their time building sustained defenses that prevent threats day after day. However, they must be ready to hit a sprint whenever an attack succeeds since attack duration, and the resulting damages are directly correlated.  Reacting to a successful attack is a major challenge for lean security teams today since speed tends to be a result of size. Large teams with abundant resources can respond to incidents much faster as they can expend those resources freely. Lean security teams face the same costs and resource needs but with a much smaller pool to call from. A new live webinar by XDR provider Cynet shows why that doesn't have to be the case ( register here ).  The webinar breaks down how even large enterprises struggle with time to response. Look at any of the major breaches of the past years and you'll find large security teams that overlooked red flags or mishandled their incident respons...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...

Network-attached storage (NAS) appliance maker QNAP said it's  currently   investigating  two recently patched security flaws in OpenSSL to determine their potential impact, adding it will release security updates should its products turn out to be vulnerable. Tracked as CVE-2021-3711 (CVSS score: 7.5) and CVE-2021-3712 (CVSS score: 4.4), the  weaknesses  concern a high-severity buffer overflow in SM2 decryption function and a buffer overrun issue when processing ASN.1 strings that could be abused by adversaries to run arbitrary code, cause a denial-of-service condition, or result in disclosure of private memory contents, such as private keys, or sensitive plaintext — CVE-2021-3711  - OpenSSL SM2 decryption buffer overflow CVE-2021-3712  - Read buffer overruns processing ASN.1 strings "A malicious attacker who is able present SM2 content for decryption to an application could cause attacker chosen data to overflow the buffer by up to a maximum o...

New vulnerabilities have been discovered in Fortress S03 Wi-Fi Home Security System that could be potentially abused by a malicious party to gain unauthorized access with an aim to alter system behavior, including disarming the devices without the victim's knowledge. The two unpatched issues, tracked under the identifiers CVE-2021-39276 (CVSS score: 5.3) and CVE-2021-39277 (CVSS score: 5.7), were discovered and reported by cybersecurity firm Rapid7 in May 2021 with a 60-day deadline to fix the weaknesses. The Fortress S03 Wi-Fi Home Security System is a do-it-yourself (DIY) alarm system that enables users to secure their homes and small businesses from burglars, fires, gas leaks, and water leaks by leveraging Wi-Fi and RFID technology for keyless entry. The company's security and surveillance systems are used by "thousands of clients and continued customers,"  according  to its website. Calling the vulnerabilities "trivially easy to exploit," Rapid7 re...

A group of academics has proposed a machine learning approach that uses authentic interactions between devices in Bluetooth networks as a foundation to handle device-to-device authentication reliably. Called " Verification of Interaction Authenticity " (aka VIA), the recurring authentication scheme aims to solve the problem of passive, continuous authentication and automatic deauthentication once two devices are paired with one another, which remain authenticated until an explicit deauthentication action is taken, or the authenticated session expires. "Consider devices that pair via Bluetooth, which commonly follow the pattern of pair once, trust indefinitely. After two devices connect, those devices are bonded until a user explicitly removes the bond. This bond is likely to remain intact as long as the devices exist, or until they transfer ownership," Travis Peters, one of the co-authors of the study,  said . "The increased adoption of (Bluetooth-enabled)...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  added  single-factor authentication to the short list of "exceptionally risky" cybersecurity practices that could expose critical infrastructure as well as government and the private sector entities to devastating cyberattacks. Single-factor authentication is a  method  of signing in users to websites and remote systems by using only one way of verifying their identity, typically a combination of username and password. It's considered to be of low-security, since it heavily relies on "matching one factor — such as a password — to a username to gain access to a system." But with weak, reused, and common passwords posing a grave threat and emerging a lucrative attack vector, the use of single-factor authentication can lead to unnecessary risk of compromise and increase the possibility of account takeover by cybercriminals. With the latest development, the  list of bad practices  ...
