Posted by Matthew Suozzo, Google Open Source Security Team (GOSST) Today we're excited to announce OSS Rebuild, a new project to strengthen trust in open source package ecosystems by reproducing upstream artifacts. As supply chain attacks continue to target widely-used dependencies, OSS Rebuild gives security teams powerful data to avoid compromise without burden on upstream maintainers. The project comprises: Automation to derive declarative build definitions for existing PyPI (Python), npm (JS/TS), and Crates.io (Rust) packages. SLSA Provenance for thousands of packages across our supported ecosystems, meeting SLSA Build Level 3 requirements with no publisher intervention. Build observability and verification tools that security teams can integrate into their existing vulnerability management workflows. Infrastructure definitions to allow organizations to easily run their own instances of OSS Rebuild to rebuild, generate, sign, and…

The China-linked cyber espionage group tracked as APT41 has been attributed to a new campaign targeting government IT services in the African region. "The attackers used hardcoded names of internal services, IP addresses, and proxy servers embedded within their malware," Kaspersky researchers Denis Kulik and Daniil Pogorelov said. "One of the C2s [command-and-control servers] was a captive

Cybersecurity researchers have unearthed new Android spyware artifacts that are likely affiliated with the Iranian Ministry of Intelligence and Security (MOIS) and have been distributed to targets by masquerading as VPN apps and Starlink, a satellite internet connection service offered by SpaceX. Mobile security vendor Lookout said it discovered four samples of a surveillanceware tool it tracks

By 2025, Zero Trust has evolved from a conceptual framework into an essential pillar of modern security. No longer merely theoretical, it’s now a requirement that organizations must adopt. A robust, defensible architecture built on Zero Trust principles does more than satisfy baseline regulatory mandates. It underpins cyber resilience, secures third-party partnerships, and ensures uninterrupted

Even in well-secured environments, attackers are getting in—not with flashy exploits, but by quietly taking advantage of weak settings, outdated encryption, and trusted tools left unprotected. These attacks don’t depend on zero-days. They work by staying unnoticed—slipping through the cracks in what we monitor and what we assume is safe. What once looked suspicious now blends in, thanks to
