With so many overlapping and self-serving definitions of XDR (Extended Detection and Response), embracing the innovations in technology first require that we parse the alphabet soup. We agree with several industry analysts covering the space that XDR is a vendor push with no real customer demand, but the problem spaces within XDR are of significant customer interest. Consensus has emerged on a few XDR elements such as: cloud-native/SaaS, improved detection, and improved response.

A lot has changed since Sumo Logic last gave our two cents on how to secure Office 365. In the meantime, Office 365 has become Microsoft 365 (M365), and Sumo has continued evolving and expanding its security offering. Today’s threat actor is adept at compromising M365 accounts through various methods. Stealing credentials through phishing email campaigns and brute-force attacks has become commonplace.

The Sumo Logic Threat Labs team previously outlined the risks associated with unprotected cloud credentials found on Windows endpoints. This article builds on that work by providing detection and hunting guidance in the context of endpoints that run the Linux operating system. Although workloads that support business functionality are increasingly moving to the cloud, these workloads are often managed through an endpoint that is often found on premises.

Open source security tools are no longer experimental or only used by hobbyists. They protect some of the largest global enterprises and critical digital infrastructure. This evolution occurred more rapidly than anyone imagined or predicted.

The need for fast incident response is a given. No industry professional would deny how critical a rapid response is when dealing with a cyber threat and an incident. However, it is equally important to understand that the quickest response is not always the best in cybersecurity. Security operations centers (SOCs) and organizations must factor in other variables, too, when preparing for the inevitable, as recent cyber stats suggest.

Almost every day we hear of another data breach. There has been no shortage of headline-hitting breaches here in Australia, such as Medibank and Optus. The old-school method of ransomware encrypting any data it has access to and requesting a ransom for the decryption key to restore data has evolved. It is now a more insidious and far-reaching problem involving bad actors exfiltrating data and requesting a ransom to keep from exposing that data publicly.
