Monitor contextual data about a file that may highlight embedded payloads, which may include information such as name, the content (ex: signature, headers, or data/media), file size, etc. Abnormal file sizes may be an indicator of embedded content. Monitor for newly constructed files containing large amounts of data.

On Windows 10, enable Attack Surface Reduction (ASR) rules to prevent execution of potentially obfuscated scripts. Īnti-virus can be used to automatically detect and quarantine suspicious files.

The SMOKEDHAM source code is embedded in the dropper as an encrypted string. Netwalker's DLL has been embedded within the PowerShell script in hex format. MacOS.OSAMiner has embedded Stripped Payloads within another run-only Stripped Payloads.
Invoke-PSImage can be used to embed payload data within a new image file. ĭtrack has used a dropper that embeds an encrypted payload as extra data. The DEADEYE.EMBED variant of DEADEYE has the ability to embed payloads inside of a compiled binary. ĬomRAT has embedded a XOR encrypted communications module inside the orchestrator module. įor C0021, the threat actors embedded a base64-encoded payload within a LNK file. For example, an embedded module may be injected into default browsers, allowing adversaries to then communicate via the network. These embedded then injected payloads may be used as part of the modules of malware designed to provide specific features such as encrypting C2 communications in support of an orchestrator module. Įmbedded content may also be used as Process Injection payloads used to infect benign system processes. Adversaries have also been observed nesting payloads (such as executables and run-only scripts) inside a file of the same format. įor example, adversaries have been observed embedding payloads within or as an overlay of an otherwise benign binary. This is similar to Steganography, though does not involve weaving malicious content into specific bytes and patterns related to legitimate digital media formats. Īdversaries may embed payloads in various file formats to hide payloads. In some cases, embedded payloads may also enable adversaries to Subvert Trust Controls by not impacting execution controls such as digital signatures and notarization tickets. Otherwise seemingly benign files (such as scripts and executables) may be abused to carry and obfuscate malicious payloads and content. Adversaries may embed payloads within other files to conceal malicious content from defenses.
