Threat response is a cornerstone of cloud security, but its roots lie in the early days of antivirus software. Back then, responding to threats was fairly linear and straightforward — stop the malicious process, quarantine it, remove or delete if necessary, and move on. However, modern cloud environments have revolutionized how threats operate, making it clear just how much the game has changed.

Cloud security teams are often faced with an onslaught of noise from their detection tooling, making it nearly impossible to distinguish truly malicious threats from benign behaviors. Many threats will go uninvestigated simply because there aren’t enough analysts for the sheer amount of alerts, leaving organizations exposed to potential breaches.

Plugins are shared libraries that conform to a documented API, hooking into the core functionalities of Falco to allow things such as adding new event sources that can be evaluated using filtering expressions/Falco rules. Since Falco is open source, users can build plugins for just about any arbitrary 3rd party event source. In recent blog posts, we discussed how Falco can be extended to event stream sources such as Gitlab, Salesforce and Box via the Falco Plugin architecture.

Vulnerability management in the cloud is more challenging than ever. Security teams are drowning in vulnerability alerts, asked to deal with them quickly even as the list continues to expand. What they lack is a clear path to remediation. Legacy tools flood teams with critical alerts, while offering little guidance on which fixes will be most impactful. Vulnerability management isn’t just about identifying the biggest risks — it’s about taking decisive action.

Organizations benefit from the speed of the cloud, but with great power comes great responsibility. An inadvertent cloud misconfiguration can leave the door open to bad actors. While cloud configuration issues most often stem from human error or lack of awareness, they are unfortunately a leading cause of data breaches.

Identities have become one of the most common ways modern threat actors gain a foothold in the cloud. From stolen credentials to overly permissive roles and privilege escalation, attackers use a range of tactics to exploit identities and use them to launch devastating breaches. Once inside your environment, they can move laterally, exploit resources, or steal sensitive data, leaving security teams scrambling to contain the damage.

Since the Sysdig Threat Research Team (TRT) discovered LLMjacking in May 2024, we have continued to observe new insights into and applications for these attacks. Large language models (LLMs) are rapidly evolving and we are all still learning how best to use them, but in the same vein, attackers continue to evolve and grow their use cases for misuse.

In the early 2000s, one of the hardest choices many of us faced online was selecting our MySpace “Top 8” — the ultimate public display of friendship. Choosing which friends to feature required serious thought, some strategic prioritization, and let’s be honest — risking a few hurt feelings. I wonder if Tom still thinks about the impossible position he created for a generation of young internet users.
