Windows SprySOCKS Malware: Advanced Kernel-Level Rootkit Targets Government Organizations via Supply Chain Vulnerabilities

The Windows variant of SprySOCKS malware, developed by the Chinese threat group Earth Lusca, targets government entities globally and features advanced capabilities such as rootkit-level stealth and extensive command-and-control (C2) functionalities. It operates on Windows systems, utilizing two main variants: WINDRV, which includes kernel drivers for stealth operations, and WINPLUS, a streamlined backdoor. The malware can communicate over TCP, UDP, and WebSocket, offering over 30 C2 commands for various operations, including system information gathering and keystroke logging. WINDRV loads a driver named ‘RawWNPF’ into memory using another signed kernel driver, allowing it to conceal processes and achieve persistence. The malware's design incorporates open-source elements and exploits vulnerabilities in the software supply chain, notably using a leaked certificate for driver signing. To combat SprySOCKS, organizations are advised to implement advanced endpoint detection and response (EDR) solutions, maintain regular patching, and manage supply chain risks vigilantly. The malware's adaptability and reliance on legitimate certificates complicate detection efforts, necessitating continuous refinement of security practices.

Android Apps Get Public Verification System to Stop Supply Chain Attacks

Google has launched an enhanced Binary Transparency initiative for Android to strengthen the ecosystem against supply chain attacks. This initiative builds on the Pixel Binary Transparency framework introduced in October 2021, which ensures Pixel devices operate on verified OS software through a public cryptographic log of factory images. The new initiative aims to address the increasing sophistication of binary supply chain attacks, emphasizing that a binary's digital signature alone is insufficient for guaranteeing its authenticity. Starting May 1, 2026, all production Android applications released by Google will include a cryptographic entry confirming their authenticity. This initiative covers various Google applications and provides a transparent 'Source of Truth' for users to verify the software on their devices. Google is also offering verification tools for users and researchers to confirm the transparency state of supported software types, enhancing user privacy and security.

Google expands Android Binary Transparency to counter supply chain attacks

Supply chain attacks targeting mobile software have increased due to the reliance on smartphones for essential functions. In response, Google has launched an enhanced Binary Transparency program for Android, which includes a public ledger that records cryptographic entries for production applications. This program initially covers two software layers: Google Applications and Mainline Modules. For Pixel device owners, it complements the Pixel System Image Transparency feature introduced in 2023, allowing users to verify the authenticity of system images and Google applications. The program aims to address the gap in software trust by distinguishing between digital signatures, which confirm the identity of the binary's creator, and binary transparency, which indicates the intent for public release. If a Google-signed application released after May 1, 2026, is not listed in the ledger, it means Google did not authorize it as production software. Verification tools are available on GitHub for assessing software against the ledger. Google employs "defense-in-depth" protocols to mitigate insider risks, ensuring that no single individual can publish a binary without triggering cryptographic verification. The ledger acts as a public record to deter unauthorized modifications. Google is also working to extend Binary Transparency to third-party developers to enhance the security of the global software supply chain.

Brazilian LofyGang Resurfaces After Three Years With Minecraft LofyStealer Campaign

A Brazilian cybercriminal group known as LofyGang has re-emerged after three years, targeting Minecraft players with malware called LofyStealer, also known as GrabBot. This malware is disguised as a Minecraft hack named 'Slinky' and uses the official game icon to attract young users. The group has been active since late 2021 and previously leaked thousands of Minecraft accounts. The attack begins with the 'Slinky' hack, which deploys LofyStealer (identified as "chromelevator.exe") to harvest sensitive information from web browsers, including cookies, passwords, and credit card information, sending this data to a command-and-control server. ZenoX reports a shift in LofyGang's tactics from JavaScript supply chain attacks to a malware-as-a-service model, offering both free and premium tiers. Cybercriminals are increasingly exploiting trusted platforms like GitHub to distribute malware through bogus repositories and various deceptive tactics, including fake security alerts and counterfeit accounts. This trend highlights a strategy focused on volume targeting rather than precision, prompting cybersecurity experts to prioritize threats from GitHub-hosted downloads that appear legitimate.

CanisterSprawl: pgserve Compromised on npm: Malicious Versions Harvest Credentials and Exfiltrate to a Decentralized ICP Canister

On April 21, 2026, compromised versions of pgserve (1.1.11, 1.1.12, and 1.1.13) were published on npm, containing a 1,143-line credential-harvesting script that executes during the postinstall phase of npm install. The malware functions as a supply-chain worm, reinjecting itself into other packages if it finds an npm publish token. Stolen credentials are encrypted using RSA-4096 and AES-256 and exfiltrated to a decentralized Internet Computer Protocol (ICP) canister. The last legitimate release was v1.1.10, published on April 17, 2026. The malware was detected by StepSecurity AI Package Analyst and Harden Runner, which flagged the compromised versions as Critical / Rejected and confirmed live exfiltration during analysis. The injected script performs operations such as harvesting environment variables, collecting filesystem secrets, encrypting payloads, and propagating to other npm packages and Python packages if a PyPI token is detected. The exfiltration domains have been added to a global block list.

“This was not opportunistic. It was precision.” — How North Korean hackers used Microsoft Teams and Slack to compromise Windows PCs with an elaborate ploy

On March 30, 2026, axios, a JavaScript HTTP client library, was temporarily compromised by suspected North Korean hackers who hijacked maintainer Jason Saayman's account. This allowed them to publish two malicious versions of axios on npm. The malicious versions were identified and removed within three hours by StepSecurity. A post-mortem blog on GitHub provided security measures for users of Windows, macOS, and Linux, highlighting risks from a Remote Access Trojan (RAT) introduced during the breach. The attack was attributed to a group known as UNC1069, which has been active since at least 2018. Two weeks prior to the breach, Saayman was targeted in a social engineering campaign where attackers posed as a legitimate company founder, leading him to install the RAT via a fake update during a Microsoft Teams meeting. Microsoft Teams was not compromised; it was used as a delivery method for the Trojan. Saayman noted the operation's sophistication.
