On Nov. 22, 2022 Microsoft announced research findings about an ongoing supply chain attack against IoT devices running Boa web servers. The Boa web server, an open-source small-footprint web server suitable for embedded applications, was discontinued in 2005, but many software development kits still use this lightweight server on IoT hardware. Since being discontinued, vulnerabilities were discovered in Boa that make every version out there exploitable.

Amazon Security Lake allows customers to build security data lakes from integrated cloud and on-premises data sources as well as from their private applications. Directing your security telemetry into a unified data lake makes it easier to manage, analyze, and route security-log and event data to third-party SIEM solutions that leverage that telemetry.

One of our core features at LimaCharlie is building an extensible platform that security teams can use to build a robust detection and response platform. One way we accomplish this is native integration with multiple types of detection engines and languages.

The Corelight Labs team prides itself on the ability to create novel Zeek and Suricata detection content that delves deep into packet streams by leveraging the full power of these tools. However this level of additional sophistication is not always required: sometimes there are straightforward approaches that only require queries over standard Zeek logs. It’s always valuable when developing detections to keep in mind that “sometimes simple does just fine.”
