Exploiting Vulnerabilities: The Risks of Exposed SharePoint Servers

Risky Biz returns after two weeks off, and there sure is cybersecurity news to catch up on. Patrick Gray and Adam Boileau discuss:

• Microsoft tried to make outsourcing the Pentagon’s cloud maintenance to China okay (it was not)
• She shells Sharepoint by the sea-shore (by ‘she’ we mean ‘China’)
• Four (alleged) Scattered Spider members arrested (and bailed) in the UK
• Hackers spend $2700 to buy creds for a Brazilian payment system, steal $100M
• Fortinet has SQLI in the auth header, Citrix mem leak is weaponised, HP hardcodes creds and Sonicwalls get user-moderootkits. Just security vendor things!

This week’s episode is sponsored by Airlock Digital. CEO David Cottingham talks through what it takes to build a mature, resilient management platform for a security critical system.

This episode is also available on Youtube.
