Major Incidents or Breaches

Attackers exploited an authentication bypass vulnerability in N-able N-central, gaining remote administrative access to servers and potentially reaching customer systems managed through those servers. The vendor’s initial fix was incomplete, allowing continued exploitation until a subsequent update was released ^[2].
A vulnerability in COLDCARD hardware wallet firmware enabled attackers to steal approximately $88.6 million in Bitcoin from thousands of wallets, by exploiting flawed random number generation during wallet seed creation ^[5].

Thermo Fisher Scientific patched a vulnerability in select Applied Biosystems human identification software that allowed tampering with data files before analysis, making such alterations nearly undetectable ^[1].
Three high-severity vulnerabilities in Hugging Face’s Diffusers library were disclosed, which could allow malicious model repositories to execute arbitrary code on systems that load the models ^[3].

The cybersecurity threat landscape in 2026 is characterized by increasingly specialized threat actors, the use of trusted platforms as attack vectors, and the emergence of new attack surfaces due to evolving technologies ^[9].
Google is developing a Chrome security feature to block policy-installed extensions from hijacking the New Tab page or altering the default search engine by default ^[6].
