The Good
The cyber ecosystem witnessed many organizations and agencies making strides in enhancing their approaches toward malware and vulnerabilities detection. Microsoft, along with Intel, launched a new tactic called STAMINA to analyze malware using deep learning. On the other hand, Forum of Incident Response and Security Teams (FIRST) released an updated version of ‘The Guidelines for Multi-Party Vulnerability Coordination and Disclosure’ to improve the coordination and communication of vulnerability disclosure.
- Microsoft and Intel jointly released a new malware detection approach, dubbed STAMINA. Referred to as STAtic Malware-as-Image Network Analysis, the approach consists of four steps, viz. preprocessing, transfer learning, evaluation, and interpretation.
- FIRST released an updated version of ‘The Guidelines for Multi-Party Vulnerability Coordination and Disclosure’. The purpose of the guidelines is to improve coordination and communication across different stakeholders during a vulnerability disclosure.
- Microsoft is open-sourcing its threat knowledge to help the security community build protective solutions for users. The initiative has been taken following the increase in Coronavirus-related threats.
