ThreatsDay Bulletin: Defender 0-Day, SonicWall Brute-Force, 17-Year-Old Excel RCE and 15 More Stories

Recent cybersecurity reports highlight a surge in sophisticated supply chain attacks, malicious app store fraud, and critical vulnerabilities affecting major platforms like Microsoft, WordPress, and various cloud environments.

Key Points

  • Cryptocurrency service Zerion lost $100,000 after a North Korean threat actor, UNC1069, used AI-enabled social engineering to compromise a team member's credentials.
  • A fraudulent "Ledger Live" app on the Apple App Store drained $9.5 million from over 50 victims before its removal.
  • WordPress permanently removed 180,000 installations of Essential Plugin after attackers acquired the company to inject backdoors into websites.
  • Microsoft released patches for a Windows Defender privilege escalation vulnerability (RedSun) and updated RDP protections to mitigate phishing risks.
  • Raspberry Pi OS version 6.2 now disables passwordless sudo by default to improve security against unauthorized administrative access.
  • The Triad Nexus cybercrime syndicate continues to operate a $200 million fraud network by using front companies to bypass U.S. sanctions.

Why it Matters

These incidents demonstrate that even official app stores and trusted software vendors are increasingly vulnerable to sophisticated supply chain and social engineering attacks. Organizations and individual users must adopt a "zero-trust" mindset, as attackers are successfully leveraging legitimate tools and brand impersonation to bypass traditional security defenses.
