On March 31, NSFOCUS CERT detected that the npm repository of the HTTP client library Axios was poisoned by the supply chain. The attacker bypassed the normal GitHub Actions CI/CD pipeline of the project, changed the account email address of the axios maintainer to an anonymous ProtonMail address, and manually released a malicious version with a Trojan backdoor through the npm CLI. When the user installs it, a persistent remote control will be established on the host. The impact is wide-ranging, and relevant users are requested to take measures for investigation and protection as soon as possible.
This is the fifth update to the TeamPCP supply chain campaign threat intelligence report, "When the Security Scanner Became the Weapon" (v3.0, March 25, 2026). Update 004 covered developments through March 30, including the Databricks investigation, dual ransomware operations, and AstraZeneca data release. This update consolidates two days of intelligence through April 1, 2026.
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.

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.

Phishing campaigns using EvilTokens target employees in finance, HR, logistics, and sales, primarily for Business Email Compromise attacks.
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.

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.
