Threat intelligence firm GreyNoise has warned of a "coordinated brute-force activity" targeting Apache Tomcat Manager interfaces. The company said it observed a surge in brute-force and login attempts on June 5, 2025, an indication that they could be deliberate efforts to "identify and access exposed Tomcat services at scale." To that end, 295 unique IP addresses have been found to be engaged in brute-force attempts against Tomcat Manager on that date, with all of them classified as malicious. Over the past 24 hours, 188 unique IPs have been recorded, a majority of them located in the United States, the United Kingdom, Germany, the Netherlands, and Singapore. In a similar vein, 298 unique IPs were observed conducting login attempts against Tomcat Manager instances. Of the 246 IP addresses flagged in the last 24 hours, all of them are categorized as malicious and originate from the same locations. Targets of these attempts include the United States, the Uni...

Two security vulnerabilities have been disclosed in SinoTrack GPS devices that could be exploited to control certain remote functions on connected vehicles and even track their locations. "Successful exploitation of these vulnerabilities could allow an attacker to access device profiles without authorization through the common web management interface," the U.S. Cybersecurity and Infrastructure Security Agency (CISA) said in an advisory. "Access to the device profile may allow an attacker to perform some remote functions on connected vehicles such as tracking the vehicle location and disconnecting power to the fuel pump where supported." The vulnerabilities, per the agency, affect all versions of the SinoTrack IoT PC Platform. A brief description of the flaws is below - CVE-2025-5484 (CVSS score: 8.3) - Weak authentication to the central SinoTrack device management interface stems from the use of a default password and a username that's an identifier pr...

A now-patched critical security flaw in the Wazur Server is being exploited by threat actors to drop two different Mirai botnet variants and use them to conduct distributed denial-of-service (DDoS) attacks. Akamai, which first discovered the exploitation efforts in late March 2025, said the malicious campaign targets CVE-2025-24016 (CVSS score: 9.9), an unsafe deserialization vulnerability that allows for remote code execution on Wazuh servers. The security defect , which affects all versions of the server software including and above 4.4.0, was addressed in February 2025 with the release of 4.9.1. A proof-of-concept (PoC) exploit was publicly disclosed around the same time the patches were released. The problem is rooted in the Wazuh API, where parameters in the DistributedAPI are serialized as JSON and deserialized using "as_wazuh_object" in the framework/wazuh/core/cluster/common.py file. A threat actor could weaponize the vulnerability by injecting malicious JSON...

Embedded Linux-based Internet of Things (IoT) devices have become the target of a new botnet dubbed PumaBot . Written in Go, the botnet is designed to conduct brute-force attacks against SSH instances to expand in size and scale and deliver additional malware to the infected hosts. "Rather than scanning the internet, the malware retrieves a list of targets from a command-and-control (C2) server and attempts to brute force SSH credentials," Darktrace said in an analysis shared with The Hacker News. "Upon gaining access, it receives remote commands and establishes persistence using system service files." The botnet malware is designed to obtain initial access via successfully brute-forcing SSH credentials across a list of harvested IP addresses with open SSH ports. The list of IP addresses to target is retrieved from an external server ("ssh.ddos-cc[.]org"). As part of its brute-force attempts, the malware also performs various checks to determine if...

Cybersecurity researchers have disclosed that a threat actor codenamed ViciousTrap has compromised nearly 5,300 unique network edge devices across 84 countries and turned them into a honeypot-like network. The threat actor has been observed exploiting a critical security flaw impacting Cisco Small Business RV016, RV042, RV042G, RV082, RV320, and RV325 Routers (CVE-2023-20118) to corral them into a set of honeypots en masse. A majority of the infections are located in Macau, with 850 compromised devices.

What do a source code editor, a smart billboard, and a web server have in common? They've all become launchpads for attacks—because cybercriminals are rethinking what counts as "infrastructure." Instead of chasing high-value targets directly, threat actors are now quietly taking over the overlooked: outdated software, unpatched IoT devices, and open-source packages. It's not just clever—it's reshaping how intrusion, persistence, and evasion happen at scale. ⚡ Threat of the Week 5Socks Proxy Using IoT, EoL Systems Dismantled in Law Enforcement Operation — A joint law enforcement operation undertaken by Dutch and U.S. authorities dismantled a criminal proxy network, known as anyproxy[.]net and 5socks[.]net, that was powered by thousands of infected Internet of Things (IoT) and end-of-life (EoL) devices, enlisting them into a botnet for providing anonymity to malicious actors. The illicit platform, active since 2004, advertised more than 7,000 online proxies daily, with infected ...

A joint law enforcement operation undertaken by Dutch and U.S. authorities has dismantled a criminal proxy network that's powered by thousands of infected Internet of Things (IoT) and end-of-life (EoL) devices, enlisting them into a botnet for providing anonymity to malicious actors. In conjunction with the domain seizure, Russian nationals, Alexey Viktorovich Chertkov, 37, Kirill Vladimirovich Morozov, 41, Aleksandr Aleksandrovich Shishkin, 36, and Dmitriy Rubtsov, 38, a Kazakhstani national, have been charged by the U.S. Department of Justice (DoJ) for operating, maintaining, and profiting from the proxy services. The DoJ noted that users paid a monthly subscription fee, ranging from $9.95 to $110 per month, netting the threat actors more than $46 million by selling access to the infected routers. The service is believed to have been available since 2004.

The Evolving Healthcare Cybersecurity Landscape   Healthcare organizations face unprecedented cybersecurity challenges in 2025. With operational technology (OT) environments increasingly targeted and the convergence of IT and medical systems creating an expanded attack surface, traditional security approaches are proving inadequate. According to recent statistics, the healthcare sector experienced a record-breaking year for data breaches in 2024, with over 133 million patient records exposed. The average cost of a healthcare data breach has now reached $11 million, making it the most expensive industry for breaches.  What's changed dramatically is the focus of attackers. No longer content with merely extracting patient records, cybercriminals are now targeting the actual devices that deliver patient care. The stakes have never been higher, with ransomware now representing 71% of all attacks against healthcare organizations and causing an average downtime of 11 days per inc...

Cybersecurity researchers have detailed a malware campaign that's targeting Docker environments with a previously undocumented technique to mine cryptocurrency. The activity cluster, per Darktrace and Cado Security , represents a shift from other cryptojacking campaigns that directly deploy miners like XMRig to illicitly profit off the compute resources. This involves deploying a malware strain that connects to a nascent Web3 service called Teneo, a decentralized physical infrastructure network (DePIN) that allows users to monetize public social media data by running a Community Node in exchange for rewards called Teneo Points , which can be converted into $TENEO Tokens. The node essentially functions as a distributed social media scraper to extract posts from Facebook, X, Reddit, and TikTok. An analysis of artifacts gathered from Darktrace's honeypots has revealed that the attack starts with a request to launch a container image " kazutod/tene:ten " from the ...

Cybersecurity researchers are warning of continued risks posed by a distributed denial-of-service (DDoS) malware known as XorDDoS , with 71.3 percent of the attacks between November 2023 and February 2025 targeting the United States. "From 2020 to 2023, the XorDDoS trojan has increased significantly in prevalence," Cisco Talos researcher Joey Chen said in a Thursday analysis.  "This trend is not only due to the widespread global distribution of the XorDDoS trojan but also an uptick in malicious DNS requests linked to its command-and-control (C2) infrastructure. In addition to targeting commonly exposed Linux machines, the trojan has expanded its reach to Docker servers, converting infected hosts into bots." Nearly 42 percent of the compromised devices are located in the United States, followed by Japan, Canada, Denmark, Italy, Morocco, and China. XorDDoS is a well-known malware that has a track record of striking Linux systems for over a decade. In May 2022...

A critical security vulnerability has been disclosed in the Erlang/Open Telecom Platform (OTP) SSH implementation that could permit an attacker to execute arbitrary code sans any authentication under certain conditions. The vulnerability, tracked as CVE-2025-32433 , has been given the maximum CVSS score of 10.0. "The vulnerability allows an attacker with network access to an Erlang/OTP SSH server to execute arbitrary code without prior authentication," Ruhr University Bochum researchers Fabian Bäumer, Marcus Brinkmann, Marcel Maehren, and Jörg Schwenk said . The issue stems from improper handling of SSH protocol messages that essentially permit an attacker to send connection protocol messages prior to authentication. Successful exploitation of the shortcomings could result in arbitrary code execution in the context of the SSH daemon . Further exacerbating the risk, if the daemon process is running as root, it enables the attacker to have full control of the device, in ...

An unpatched security flaw impacting the Edimax IC-7100 network camera is being exploited by threat actors to deliver Mirat botnet malware variants since at least May 2024. The vulnerability in question is CVE-2025-1316 (CVSS v4 score: 9.3), a critical operating system command injection flaw that an attacker could exploit to achieve remote code execution on susceptible devices by means of a specially crafted request. Web infrastructure and security company Akamai said the earliest exploit attempt targeting the flaw dates back to May 2024, although a proof-of-concept (PoC) exploit has been publicly available since June 2023. "The exploit targets the /camera-cgi/admin/param.cgi endpoint in Edimax devices, and injects commands into the NTP_serverName option as part of the ipcamSource option of param.cgi," Akamai researchers Kyle Lefton and Larry Cashdollar said . While weaponizing the endpoint requires authentication, it has been found that the exploitation attempts are...
