A previously undocumented China-aligned advanced persistent threat (APT) group named PlushDaemon has been linked to a supply chain attack targeting a South Korean virtual private network (VPN) provider in 2023, according to new findings from ESET. "The attackers replaced the legitimate installer with one that also deployed the group's signature implant that we have named SlowStepper – a feature-rich backdoor with a toolkit of more than 30 components," ESET researcher Facundo Muñoz said in a technical report shared with The Hacker News. PlushDaemon is assessed to be a China-nexus group that has been operational since at least 2019, targeting individuals and entities in China, Taiwan, Hong Kong, South Korea, the United States, and New Zealand. Central to its operations is a bespoke backdoor called SlowStepper, which is described as a large toolkit consisting of around 30 modules, programmed in C++, Python, and Go. Another crucial aspect of its attacks is the hijackin...

Oracle is urging customers to apply its January 2025 Critical Patch Update (CPU) to address 318 new security vulnerabilities spanning its products and services. The most severe of the flaws is a bug in the Oracle Agile Product Lifecycle Management (PLM) Framework (CVE-2025-21556, CVSS score: 9.9) that could allow an attacker to seize control of susceptible instances. "Easily exploitable vulnerability allows low privileged attackers with network access via HTTP to compromise Oracle Agile PLM Framework," according to a description of the security hole in the NIST National Vulnerability Database (NVD). It's worth noting that Oracle warned of active exploitation attempts against another flaw in the same product (CVE-2024-21287, CVSS score: 7.5) in November 2024. Both vulnerabilities affect Oracle Agile PLM Framework version 9.3.6. "Customers are strongly advised to apply the January 2025 Critical Patch Update for Oracle Agile PLM Framework as it includes patche...

Web infrastructure and security company Cloudflare on Tuesday said it detected and blocked a 5.6 Terabit per second (Tbps) distributed denial-of-service (DDoS) attack, the largest ever attack to be reported to date. The UDP protocol-based attack took place on October 29, 2024, targeting one of its customers, an unnamed internet service provider (ISP) from Eastern Asia. The activity originated from a Mirai -variant botnet. "The attack lasted only 80 seconds and originated from over 13,000 IoT devices," Cloudflare's Omer Yoachimik and Jorge Pacheco said in a report. That said, the average unique source IP address observed per second was 5,500, with the average contribution of each IP address per second around 1 Gbps. The previous record for the largest volumetric DDoS assault was also reported by Cloudflare in October 2024, which peaked at 3.8 Tbps. Cloudflare also revealed it blocked approximately 21.3 million DDoS attacks in 2024, a 53% increase from 2023, and th...

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 -...

Cybersecurity researchers have warned of a new large-scale campaign that exploits security flaws in AVTECH IP cameras and Huawei HG532 routers to rope the devices into a Mirai botnet variant dubbed Murdoc Botnet. The ongoing activity "demonstrates enhanced capabilities, exploiting vulnerabilities to compromise devices and establish expansive botnet networks," Qualys security researcher Shilpesh Trivedi said in an analysis. The campaign is known to be active since at least July 2024, with over 1,370 systems infected to date. A majority of the infections have been located in Malaysia, Mexico, Thailand, Indonesia, and Vietnam. Evidence shows that the botnet leverages known security flaws such as CVE-2017-17215 and CVE-2024-7029 to gain initial access to the Internet of Things (IoT) devices and download the next stage payload by means of a shell script. The script, for its part, fetches the botnet malware and executes it depending on the CPU architecture. The end goal of ...

A global network of about 13,000 hijacked Mikrotik routers has been employed as a botnet to propagate malware via spam campaigns, the latest addition to a list of botnets powered by MikroTik devices. The activity "take[s] advantage of misconfigured DNS records to pass email protection techniques," Infoblox security researcher David Brunsdon said in a technical report published last week. "This botnet uses a global network of Mikrotik routers to send malicious emails that are designed to appear to come from legitimate domains." The DNS security company, which has codenamed the campaign Mikro Typo , said its analysis sprang forth from the discovery of a malspam campaign in late November 2024 that leveraged freight invoice-related lures to entice recipients into launching a ZIP archive payload. The ZIP file contains an obfuscated JavaScript file, which is then responsible for running a PowerShell script designed to initiate an outbound connection to a command-a...

A former analyst working for the U.S. Central Intelligence Agency (CIA) pleaded guilty to transmitting top secret National Defense Information (NDI) to individuals who did not have the necessary authorization to receive it and attempted to cover up the activity. Asif William Rahman, 34, of Vienna, was an employee of the CIA since 2016 and had a Top Secret security clearance with access to Sensitive Compartmented Information (SCI). He was charged with two counts of unlawfully transmitting NDI in November 2024 following his arrest in Cambodia. He has pleaded guilty to two counts of willful retention and transmission of classified information related to the national defense. He is expected to be sentenced on May 15, 2025, potentially facing a maximum penalty of 10 years in prison. According to court filings , Rahman is alleged to have retained without authorization two documents classified as Top Secret on or about October 17, 2024, and delivered it to multiple individuals who wer...

Imagine receiving a penetration test report that leaves you with more questions than answers. Questions like, "Were all functionalities of the web app tested?" or " Were there any security issues that could have been identified during testing?" often go unresolved, raising concerns about the thoroughness of the security testing. This frustration is common among many security teams. Pentest reports, while crucial, frequently lack the depth and detail necessary to truly assess the success of the project. Even with years of experience working with cybersecurity teams and managing ethical hacking projects, we frequently encountered these same issues. Whether collaborating with external pentest providers or managing our own projects as founders of Hackrate , we often faced difficulties in ensuring that the testing was as comprehensive as it needed to be. This realization inspired us to create HackGATE , a managed gateway solution built to bring transparency and contro...

Cybersecurity researchers are calling attention to a series of cyber attacks that have targeted Chinese-speaking regions like Hong Kong, Taiwan, and Mainland China with a known malware called ValleyRAT. The attacks leverage a multi-stage loader dubbed PNGPlug to deliver the ValleyRAT payload, Intezer said in a technical report published last week. The infection chain commences with a phishing page that's designed to encourage victims to download a malicious Microsoft Installer (MSI) package disguised as legitimate software.  Once executed, the installer deploys a benign application to avoid arousing suspicion, while also stealthily extracting an encrypted archive containing the malware payload. "The MSI package uses the Windows Installer's CustomAction feature, enabling it to execute malicious code, including running an embedded malicious DLL that decrypts the archive (all.zip) using a hardcoded password 'hello202411' to extract the core malware components,...

The Computer Emergency Response Team of Ukraine (CERT-UA) is warning of ongoing attempts by unknown threat actors to impersonate the cybersecurity agency by sending AnyDesk connection requests. The AnyDesk requests claim to be for conducting an audit to assess the "level of security," CERT-UA added, cautioning organizations to be on the lookout for such social engineering attempts that seek to exploit user trust. "It is important to note that CERT-UA may, under certain circumstances, use remote access software such as AnyDesk," CERT-UA said . "However, such actions are taken only after prior agreement with the owners of objects of cyber defense through officially approved communication channels." However, for this attack to succeed, it's necessary that the AnyDesk remote access software is installed and operational on the target's computer. It also requires the attacker to be in possession of the target's AnyDesk identifier , suggesting th...

New research has uncovered security vulnerabilities in multiple tunneling protocols that could allow attackers to perform a wide range of attacks. "Internet hosts that accept tunneling packets without verifying the sender's identity can be hijacked to perform anonymous attacks and provide access to their networks," Top10VPN said in a study, as part of a collaboration with KU Leuven professor and researcher Mathy Vanhoef. As many as 4.2 million hosts have been found susceptible to the attacks, including VPN servers, ISP home routers, core internet routers, mobile network gateways, and content delivery network (CDN) nodes. China, France, Japan, the U.S., and Brazil top the list of the most affected countries. Successful exploitation of the shortcomings could permit an adversary to abuse a susceptible system as one-way proxies, as well as conduct denial-of-service (DoS) attacks. "An adversary can abuse these security vulnerabilities to create one-way proxies an...

The Threat actor known as DoNot Team has been linked to a new Android malware as part of highly targeted cyber attacks. The artifacts in question, named Tanzeem (meaning "organization" in Urdu) and Tanzeem Update, were spotted in October and December 2024 by cybersecurity company Cyfirma. The apps in question have been found to incorporate identical functions, barring minor modifications to the user interface. "Although the app is supposed to function as a chat application, it does not work once installed, shutting down after the necessary permissions are granted," Cyfirma noted in a Friday analysis. "The app's name suggests that it is designed to target specific individuals or groups both inside and outside the country." DoNot Team, also tracked as APT-C-35, Origami Elephant, SECTOR02, and Viceroy Tiger, is a hacking group believed to be of Indian origin, with historical attacks leveraging spear-phishing emails and Android malware families to...
