The Elastic Common Schema (ECS) provides an open, consistent model for structuring your data in the Elastic Stack. By normalizing data to a single common model, you can uniformly examine your data using interactive search, visualizations, and automated analysis. Elastic provides hundreds of integrations that are ECS-compliant out of the box, but ECS also allows you to normalize custom data sources. Normalizing a custom source can be an iterative and sometimes time-intensive process.

How often do you check your event log monitor for potential security breaches? Did you know that many potential security breaches, events, and other problems are logged to event logs? Unfortunately, even the most skilled IT professionals have a hard time making sense of what to watch for that could indicate security issues or even a potential breach until it is too late. Event logs contain a ton of information that can be useful.

A ransomware attack is a bug that we can’t shake off. Or perhaps, it can even be called a shape-shifter that somehow finds a way into networks, no matter how many armed sentries you’ve deployed in and around your perimeter. The line between ransomware and a data breach is slowly fading. Threat actors prefer ransomware over other modes of attack because they work.

CVE-2020-13942 is a critical vulnerability that affects the Apache open source application Unomi, and allows a remote attacker to execute arbitrary code. In the versions prior to 1.5.1, Apache Unomi allowed remote attackers to send malicious requests with MVEL and OGNL expressions that could contain arbitrary code, resulting in Remote Code Execution (RCE) with the privileges of the Unomi application.

Microsoft recently announced a campaign by a sophisticated nation-state threat actor, operating from China, to exploit a collection of 0-day vulnerabilities in Microsoft Exchange and exfiltrate customer data. They’re calling the previously unknown hacking gang Hafnium. Microsoft has apparently been aware of Hafnium for a while — they do describe the group’s historical targets.
