The Axios NPM package was compromised through a supply chain attack attributed to North Korean threat actors. Attackers exploited a long-lived NPM access token to bypass GitHub Actions' OIDC-based CI/CD publishing workflow, enabling them to push backdoored versions of the package. This breach allows malicious code to be distributed to developers and applications relying on Axios, a widely used HTTP client library in JavaScript environments. Although no known exploits in the wild have been reported yet, the potential for widespread impact exists due to Axios's extensive use in web and mobile applications. The attack highlights vulnerabilities in CI/CD pipeline security and token management. Mitigation requires immediate revocation of compromised tokens, strengthening CI/CD authentication mechanisms, and vigilant monitoring of package integrity. Countries with significant software development sectors and heavy reliance on JavaScript ecosystems, including the United States, India, Germany, South Korea, Japan, and the United Kingdom, are most at risk. Given the ease of exploitation and potential for supply chain compromise, the severity is assessed as high despite the current low severity rating. Defenders must prioritize securing CI/CD workflows and verifying package authenticity to prevent similar attacks.
In March 2026, a new MaaS active campaign was discovered promoting previously unknown malware in private Telegram chats. The Trojan features an extensive arsenal of capabilities. On the panel provided to third‑party actors, in addition to the standard features of RAT‑like malware, a stealer, keylogger, clipper, and spyware are also available.
A sophisticated malware campaign targeting WhatsApp users has been observed since February 2026. The attack chain begins with malicious Visual Basic Script files sent via WhatsApp messages, which, when executed, initiate a multi-stage infection process. The malware uses renamed Windows utilities, retrieves payloads from trusted cloud services, and installs malicious MSI packages. The campaign employs social engineering, stealth techniques, and cloud-based payload hosting to establish persistence and escalate privileges on victim systems. The attackers utilize legitimate tools and trusted platforms to reduce visibility and increase the likelihood of successful execution. The final stage involves the delivery of unsigned MSI installers that enable remote access to compromised systems.
A coordinated supply chain attack targeted the axios npm package, compromising two versions (1.14.1 and 0.30.4) by injecting a malicious dependency. The attack delivered a cross-platform Remote Access Trojan to macOS, Windows, and Linux systems. The compromise occurred through the lead maintainer's npm account, bypassing normal publishing workflows. The malicious payload performed system reconnaissance, established persistence on Windows, and provided remote access capabilities. The attack affected numerous organizations and potentially exposed sensitive credentials. Immediate mitigation steps include pinning to safe versions, removing malicious dependencies, rotating credentials, and blocking the command and control server.

GhostSocks is an emerging threat that turns compromised devices into residential proxy nodes, enabling attackers to evade detection. Originally marketed on Russian underground forums as Malware-as-a-Service, it has gained popularity due to its partnership with Lumma Stealer. Written in GoLang, GhostSocks uses SOCKS5 proxy protocol and TLS encryption to blend malicious traffic into normal network activity. It also incorporates backdoor functionality for running arbitrary commands and deploying additional payloads. Darktrace observed an increase in GhostSocks activity, detecting it alongside Lumma Stealer in customer networks. The malware's versatility in converting devices into proxy nodes while enabling covert network access illustrates how threat actors maximize the value of compromised infrastructure.
CrySome is a sophisticated .NET-based remote access trojan designed for persistent command-and-control operations. It features advanced persistence mechanisms, including recovery partition abuse and offline registry modification, allowing it to survive system resets. The malware incorporates an aggressive defense evasion module, disabling security products and blocking updates. Key capabilities include command execution, file operations, surveillance, credential theft, and hidden virtual desktop control. CrySome's modular architecture and structured packet-based protocol enable a wide range of remote operations. Its emphasis on stealth, resilience, and comprehensive system control makes it a significant threat for long-term covert access to compromised environments.
A sophisticated phishing campaign targeting LinkedIn users has been identified. The attack uses fake LinkedIn message notifications to lure victims into clicking on malicious links. The emails closely mimic legitimate LinkedIn communications, including spoofed display names and formatting. Upon clicking, users are redirected to a convincing but fraudulent LinkedIn login page designed to steal credentials. The phishing page uses a deceptive domain name similar to 'LinkedIn' to further trick users. This campaign demonstrates the evolving tactics of cybercriminals in exploiting human trust and curiosity. The analysis emphasizes the importance of vigilance, source verification, and caution when interacting with seemingly routine notifications.

Ransomware is increasingly targeting home backups on NAS, cloud storage, and external drives. Here’s how these attacks work, and how to keep your family photos and documents safe.
An unknown threat actor compromised the npm account of an axios maintainer, publishing two malicious versions of the package. These versions introduced a dependency on plain-crypto-js, a newly created malicious package. Despite quick removal, axios's widespread usage led to rapid exposure. The malicious package includes a dropper that downloads and executes platform-specific second-stage payloads, functioning as remote access trojans. These payloads can execute remote shells, inject binaries, browse directories, list processes, and perform system reconnaissance. Organizations are advised to audit their environments, remove malicious artifacts, rotate exposed credentials, investigate potential compromise paths, and monitor for suspicious activity.
In case of a cyber incident, most organizations fear more of data loss (via exfiltration) than regular data encryption because they have a good backup policy in place. If exfiltration happened, it means a total loss of control of the stolen data with all the consequences (PII, CC numbers, …).

A lot of the information seen on DShield honeypots [1] is repeated bot traffic, especially when looking at the Cowrie [2] telnet and SSH sessions. However, how long a session lasts, how many commands are run per session and what the last commands run before a session disconnects can vary. Some of this information could help indicate whether a session is automated and if a honeypot was fingerprinted. This information can also be used to find more interesting honeypot sessions.
TeamPCP launched a sophisticated attack on the Telnyx Python SDK, publishing malicious versions 4.87.1 and 4.87.2 to PyPI. The attack represents an evolution from their previous LiteLLM campaign, incorporating WAV-based steganography, split-file code injection, and expanded platform support. The payload, activated on import, uses stealthy techniques to download and execute credential-stealing malware across Linux, macOS, and Windows systems. Key changes include the use of audio steganography to hide malicious code, improved evasion through split-file injection, and the addition of Windows support with Startup folder persistence. The attackers shifted from HTTPS to plaintext HTTP infrastructure, potentially exposing their activities to network monitoring. Organizations are advised to downgrade to the last clean version and treat affected systems as compromised.
