Government, financial, and industrial organizations located in Asia, Africa, and Latin America are the target of a new campaign dubbed PassiveNeuron , according to findings from Kaspersky. The cyber espionage activity was first flagged by the Russian cybersecurity vendor in November 2024, when it disclosed a set of attacks aimed at government entities in Latin America and East Asia in June, using never-before-seen malware families tracked as Neursite and NeuralExecutor. It also described the operation as exhibiting a high level of sophistication, with the threat actors leveraging already compromised internal servers as an intermediate command-and-control (C2) infrastructure to fly under the radar. "The threat actor is able to move laterally through the infrastructure and exfiltrate data, optionally creating virtual networks that allow attackers to steal files of interest even from machines isolated from the internet," Kaspersky noted at the time. "A plugin-based ap...

Cybersecurity researchers have disclosed details of a high-severity flaw impacting the popular async-tar Rust library and its forks, including tokio-tar, that could result in remote code execution under certain conditions. The vulnerability, tracked as CVE-2025-62518 (CVSS score: 8.1), has been codenamed TARmageddon by Edera, which discovered the issue in late August 2025. It impacts several widely-used projects, such as testcontainers and wasmCloud. "In the worst-case scenario, this vulnerability has a severity of 8.1 (High) and can lead to Remote Code Execution (RCE) through file overwriting attacks, such as replacing configuration files or hijacking build backends," the Seattle-based security company said . The problem is compounded by the fact that tokio-tar is essentially abandonware despite attracting thousands of downloads via crates.io. Tokio-tar is a Rust library for asynchronously reading and writing TAR archives built atop the Tokio runtime for the programmi...

TP-Link has released security updates to address four security flaws impacting Omada gateway devices, including two critical bugs that could result in arbitrary code execution. The vulnerabilities in question are listed below - CVE-2025-6541 (CVSS score: 8.6) - An operating system command injection vulnerability that could be exploited by an attacker who can log in to the web management interface to run arbitrary commands CVE-2025-6542 (CVSS score: 9.3) - An operating system command injection vulnerability that could be exploited by a remote unauthenticated attacker to run arbitrary commands CVE-2025-7850 (CVSS score: 9.3) - An operating system command injection vulnerability that could be exploited by an attacker in possession of an administrator password of the web portal to run arbitrary commands CVE-2025-7851 (CVSS score: 8.7) - An improper privilege management vulnerability that could be exploited by an attacker to obtain the root shell on the underlying operating sys...

Meta on Tuesday said it's launching new tools to protect Messenger and WhatsApp users from potential scams. To that end, the company said it's introducing new warnings on WhatsApp when users attempt to share their screen with an unknown contact during a video call so as to prevent them from giving away sensitive information like bank details or verification codes. On Messenger, users can opt to enable a setting called "Scam detection" by navigating to Privacy & safety settings. Once it's turned on, users are alerted when they receive a potentially suspicious message from an unknown connection that may contain signs of a scam. "Because detection happens on your device, chats with end-to-end encryption stay secure," Meta said in a support document. "If you’re notified that a chat may contain signs of a scam, we'll ask if you'd like to send recent messages you received to AI review. Messages that are shared with AI are no longer end-...

Cybersecurity researchers have shed light on the inner workings of a botnet malware called PolarEdge . PolarEdge was first documented by Sekoia in February 2025, attributing it to a campaign targeting routers from Cisco, ASUS, QNAP, and Synology with the goal of corralling them into a network for an as-yet-undetermined purpose. The TLS-based ELF implant, at its core, is designed to monitor incoming client connections and execute commands within them. Then, in August 2025, attack surface management platform Censys detailed the infrastructural backbone powering the botnet, with the company noting that PolarEdge exhibits characteristics that are consistent with an Operational Relay Box (ORB) network. There is evidence to suggest that the activity involving the malware may have started as far back as June 2023. In the attack chains observed in February 2025, the threat actors have been observed exploiting a known security flaw impacting Cisco routers (CVE-2023-20118) to download a ...
