Cybersecurity Brief – 2025-06-09
Major Incidents or Breaches
- A supply chain attack targeting npm and PyPI ecosystems has been identified, affecting over a dozen packages associated with GlueStack. The attack delivers malware via a change to “lib/commonjs/index.js,” potentially impacting millions globally.
- Over 700 users across Latin America, primarily in Brazil, have been infected since early 2025 through a campaign distributing malicious Chromium-based browser extensions designed to steal user data.
Newly Discovered Vulnerabilities
- A command injection vulnerability in TBK DVR-4104 and DVR-4216 digital video recording devices is being actively exploited by a new Mirai botnet variant, enabling attackers to hijack vulnerable devices.
Notable Threat Actor Activity
- Cybercriminals are leveraging software supply chain attacks by compromising widely used npm and PyPI packages to distribute malware at scale.
- Threat actors are targeting Latin American users with malicious browser extensions, focusing on Chromium-based browsers to exfiltrate sensitive information.
- Mirai botnet operators have adapted their malware to exploit vulnerabilities in digital video recorders, expanding their botnet infrastructure through IoT device compromise.
Trends, Tools, or Tactics of Interest
- Increased targeting of software supply chains, particularly open-source package repositories (npm, PyPI), as a vector for widespread malware distribution.
- Use of browser extensions as a method for credential and data theft, specifically targeting users in Latin America.
- Continued adaptation of IoT botnets (Mirai) to exploit newly discovered vulnerabilities in networked devices, maintaining persistence and expanding reach.
