"value" : "Attackers have been successfully deploying RATs for years to remotely control users systems - giving them full access to the victim\u00e2\u20ac\u2122s files or resources such as cameras, recording key strokes, or downloading further malware. Traditionally RATs have been deployed when a user opens an email attachment, or downloads a file from a website or peer-to-peer network. In both cases, these vectors involve use of files to deliver the payload - which are easier to detect.\r\n\r\nRecently we detected a more sophisticated technique that a handful of countries across Asia are actively using to infect systems with RATs. This new technique ensures that the payload/file remains in memory through its execution, never touching the disk in a de-encrypted state. In doing so, the attacker can remain out of view from antivirus technologies, and even \u00e2\u20ac\u02dcnext-generation\u00e2\u20ac\u2122 technologies that only focus on file-based threat vectors. Also, the samples analyzed have the ability detect the presence of a virtual machine to ensure it\u00e2\u20ac\u2122s not being analyzed in a network sandbox.\r\n\r\nAnd finally it\u00e2\u20ac\u2122s important to highlight that the RAT itself is not new. In fact this technique can be used to deliver any \u00e2\u20ac\u0153known\u00e2\u20ac\u009d RAT to a victim\u00e2\u20ac\u2122s system. We analyzed this sample against our SentinelOne EPP to confirm is does not evade our behavior-based detection mechanisms. This is due to the fact that we\u00e2\u20ac\u2122re monitoring all processes at the user-space/kernel-space interface - and because all communication between the application and the kernel must be unencrypted, we detect the sample at both process-injection points."
