Microsoft 365 Becomes Prime Target for Cybercriminals
Summary
Hide ▲
Show ▼
Microsoft 365 has emerged as a primary target for cybercriminals due to its widespread adoption and integrated suite of applications. With over 400 million paid seats, the platform's dominance in email and collaboration services makes it an attractive target. Attackers exploit the interconnected nature of Microsoft 365 services, using vulnerabilities in one application to gain access to others. Recent vulnerabilities in SharePoint highlight the cascading risks associated with compromising a single service within the ecosystem. Backup systems often fail to adequately protect against sophisticated attacks, potentially reintroducing threats during recovery. Organizations must implement robust security measures, including zero-trust architecture and advanced threat protection, to mitigate these risks.

GitHub Strengthens npm Supply Chain Security with 2FA and Short-Lived Tokens
GitHub is implementing enhanced security measures to protect the npm ecosystem, including mandatory two-factor authentication (2FA) and short-lived tokens. These changes aim to mitigate supply chain attacks, such as the recent "s1ngularity", "GhostAction", and "Shai-Hulud" attacks, which involved a self-replicating worm and compromised thousands of accounts and private repositories. The measures include granular tokens with a seven-day expiration, trusted publishing using OpenID Connect (OIDC), and automatic generation of provenance attestations for packages. Additionally, GitHub is deprecating legacy tokens and TOTP 2FA, expanding trusted publishing options, and gradually rolling out these changes to minimize disruption. GitHub removed over 500 compromised packages and blocked new packages containing the Shai-Hulud malware's indicators of compromise. The company encourages NPM maintainers to use NPM-trusted publishing and strengthen publishing settings to require 2FA. Ruby Central is also tightening governance of the RubyGems package manager to improve supply-chain protections.
