Late last week cybersecurity company Red Canary published an article revealing a new strain of macOS malware they discovered. Looking at data provided by Malwarebytes they determined that this new malware, which they dubbed “Silver Sparrow,” had already infected nearly 30,000 macOS endpoints around the world.
The Uptycs threat research team recently came across multiple document samples that download Revenge RAT. The campaign currently seems to be active in Brazil. All of the malware samples we received have the same properties. One of the samples we received has the name “Rooming List Reservas para 3 Familias.docx” (SHA-256: 91611ac2268d9bf7b7cb2e71976c630f6b4bfdbb68774420bf01fd1493ed28c7). The document has only a few detections in VirusTotal.
Despite the fact that Linux server endpoints comprise 90% of cloud workloads and a majority of on-premises enterprise workloads, they don’t usually get as much attention as productivity endpoints. Most EDR solutions focus on end users and don’t meet the unique requirements for production Linux servers, such as the need for 100% uptime and low resource consumption.
Today, Uptycs is introducing enhanced detection capabilities, including a new detections UI that correlates signals (events and alerts), assigns a composite threat score, and maps the associated signals to the MITRE ATT&CK matrix. This new experience equips analysts with the context they need to quickly triage their detections queue without feeling like they’re missing anything. Watch the demo video below to see the new functionality in action.
