Top Vulnerabilities Reported in the Last 24 Hours

Bugs in VoIP apps

Five memory-corruption vulnerabilities were discovered in open-source PJSIP, which supplies an API used by VoIP phones and conference apps. The flaws can be exploited for remote code execution (RCE) in applications that use the PJSIP library. JFrog Security recommends upgrading PJSIP to version 2.12 to address the flaws.

Vulnerable medical infusion pumps

Data collected from over 200,000 medical infusion pumps reveal that 75% of them have vulnerabilities that hackers could exploit. The report shows that tens of thousands of devices are vulnerable to six critical-severity flaws reported in 2019 and 2020.

Cisco patches critical vulnerabilities

Cisco announced patches that address a couple of critical vulnerabilities in its Expressway Series and TelePresence Video Communication Server unified communications products. Tracked as CVE-2022-20754 and CVE-2022-20755, with a CVSS score of 9.0, the two vulnerabilities can be exploited by attackers to write files or execute code on the underlying operating system with root privileges.

RCE vulnerability uncovered in Hashnode

A remote code execution attack chain caused due to a local file inclusion bug in Hashnode, a blogging platform, has been discovered by security researchers. The local file inclusion vulnerability allowed users to fetch internal server files.

A stealthy browser extension called Rilide has resurfaced with improved evasion capabilities and support for Chrome’s latest extension framework. Disguised as a utility for Google Drive, it quietly collects data, particularly those tied to cryptocurrency wallets. Ongoing campaigns have used lures ranging from fake PowerPoint documents to spoofed Twitter notifications, all aimed at embedding the extension into Chromium-based browsers. On GitHub, a seemingly innocent coding challenge is being used as a delivery mechanism for malware. A malicious repository targets Polish-speaking developers and installs FogDoor, a backdoor capable of data theft, remote command execution, and persistence. The campaign uses clever techniques, while quietly harvesting sensitive information. Kubernetes environments are facing serious risk after the discovery of IngressNightmare - a collection of five critical flaws in the Ingress NGINX Controller. These bugs open the door to unauthenticated remote code execution and expose thousands of clusters to full compromise. In the wrong hands, this vulnerability could allow attackers to exfiltrate secrets across all namespaces, effectively granting full control over affected clusters.

A newly surfaced threat actor, UAT-5918, has been quietly embedding itself into Taiwan’s critical infrastructure since 2023. With a focus on information theft, the group has been targeting multiple sectors using a mix of off-the-shelf tools and stealthy web shells. The threat actor also boasts of an extensive toolkit. Meanwhile, the Medusa ransomware operation is refining its ability to bypass defenses using a malicious driver disguised as a legitimate security component. Dubbed ABYSSWORKER, the driver is signed with compromised certificates. Once deployed, it disables anti-malware tools and clears the path for ransomware delivery through a loader. On the plugin front, a critical vulnerability in WP Ghost has put thousands of WordPress sites at risk. If certain non-default settings are enabled, the bug can be used to load arbitrary files - opening the door to remote code execution. Though a patch has been issued in version 5.4.02, the exposure window combined with the plugin’s wide install base makes this a notable concern for site admins still lagging on updates.

Cybercriminals don’t just break in; they move in and redecorate. The DollyWay malware campaign, active since 2016, has now compromised over 20,000 WordPress sites, according to GoDaddy. By February 2025, it was redirecting 10 million users each month to scam sites. Originally a ransomware operation, it has evolved into a redirection scam using the VexTrio and LosPollos affiliate networks. Hackers have found a new disguise for malware—virtual hard disk files. Threat actors are distributing VenomRAT through phishing emails with .VHD files masked as purchase orders. These files help the malware evade detection while a hidden batch script self-replicates, maintains PowerShell persistence, and steals data using HVNC and Pastebin-based C2 communication. Meanwhile, a year-old sophisticated phishing campaign has shifted gears. After successfully tricking Windows users with fake Microsoft security alerts on windows[.]net, attackers are now targeting macOS users. For detailed Cyber Threat Intel, click ‘Read More’.

A new ransomware strain isn’t just locking up files, it’s locking out hope of recovery. Researchers uncovered EByte Ransomware, a Golang-based malware that’s actively targeting Windows systems with advanced cryptographic techniques, making decryption nearly impossible without the attackers' key. A simple-looking PDF is all it takes for attackers to hijack your system. A new malware strain, Phantom Goblin, is being spread through RAR attachments in phishing campaigns, tricking users into opening a malicious LNK file disguised as a document. It also abuses VSCode tunnels for remote access. Attackers don’t need new tricks when unpatched systems do the job for them. The CISA has flagged five new vulnerabilities under active exploitation, affecting Advantive VeraCore and Ivanti Endpoint Manager. The VeraCore flaw exploitation is linked to a likely Vietnamese threat group, while the Ivanti EPM vulnerabilities allow attackers to coerce credentials for further access.

When cybercriminals upgrade their arsenal, staying hidden becomes easier than ever. Several ransomware and cybercrime groups are leveraging the Ragnar Loader malware toolkit to maintain long-term access to compromised systems. Constantly evolving with new features, Ragnar Loader has become more modular and harder to detect. A single flaw in a widely used API almost handed attackers full control over vulnerable applications. The Volt API for Livewire recently patched a critical remote code execution vulnerability. The issue has been fixed in version 1.7.0, and users are strongly urged to update to prevent exploitation. A billion devices, a hidden backdoor, and tens of undocumented commands that could change everything. Security researchers have uncovered a major issue in ESP32 revealing 29 undocumented commands that attackers could exploit for spoofing devices, unauthorized data access, and long-term persistence. This vulnerability raises concerns over supply chain security, as OEMs could unknowingly ship compromised devices.
