This is why browsing these kind of websites using Internet Explorer and an outdated Flash is a bad idea. There was a new exploit revealed that is similar to this CVE.

I expect this will make it way into Rig EK at some point. Read more about that here:. The malware has a fairly easy to identify C2 checkin with interesting headers.

From the looks of it, it may be trying to patch itself. At the bottom of this long POST request filled with all of my systems data is a base64 encoded part which decodes listing registry key names, software, etc.

These were not all on my system so it seems to be static list. NET framework open-source remote access trojan family used in cyber-criminal and cyber-espionage campaigns to target Windows operating system devices.

The out-of-the-box server could not communicate with the client sample owing to the previously documented modifications that we had observed. We incorporated those changes into our build, discovering that this worked for most sample versions with almost no further modification.

Both the client and the server use the same code to serialize and encrypt the communications. Instead of compiling a different server for each client, our server uses the code from within the client to communicate with it.

Using Reflection, the server can load the assembly of the client to find the relevant functions and passwords.

This was more complex. In some cases these objects are completely different, for example the server commands to get the file system.

Our sample communicates with app. Each of these layers seems to be different to some extent in the various samples we found.

The IPacket, Serialization and Encryption framework code is shared between the client and the server, therefore we can use it with Reflection. However the Server handlers and command function are not, so we cannot create a completely perfect simulation.

After the TCP handshake completes, the server starts another handshake with the client by sending packets in the following order Figure The client returns data to the server about the victim computer, which is displayed in the server GUI Figure The server and client then enter into a keep-alive mode, where the attacker can send commands to the client and receive further responses.

The attacker can issue commands not all commands appear in different samples through the Quasar server GUI for each client:.

With further analysis of the Quasar RAT C2 Server, we uncovered vulnerabilities in the server code, which would allow remote code execution.

We did not apply this to any live C2 servers — we only tested this with our own servers in our lab.

Quasar server includes a File Manager window, allowing the attacker to select victim files, and trigger file operations — for example, uploading a file from victim machine to server.

Quasar server does not verify that the size, filename, extension, or header of the uploaded file is the same as requested. When the Quasar server retrieves the name of the uploaded file from the victim, it does not verify that it is a valid file path.

Quasar server does not even verify that a file was requested from the victim. We can respond to those commands by instead sending two files of our choice to the Quasar server.

Again, we control the content of the file, the size and the path and filename. Although Downeks has been publicly examined to some extent, our analysis found several features not previously described.

Earlier Downeks samples were all written in native code. However, among our Downeks samples, we found new versions apparently written in.

We observe many behavioral similarities and unique strings across both the native-Downeks versions, and the new. Almost all of the strings and behaviors we describe in this analysis of a.

NET version are also present in the native version. As seen in previous Downeks versions, it uses masquerades with icons, filenames and metadata imitating popular legitimate applications such as VMware workstation Figure 1 and CCleaner, or common file formats such as DOC and PDF.

All 3 samples were compiled with the same timestamp. Downeks is a backdoor with only very basic capabilities. It runs in an infinite loop, in each iteration it requests a command from the C2, and then it sleeps for a time period it receives in the C2 response defaulting to 1 second if no sleep-time sent.

The data that is sent in the POST is serialized with json, which is then is encrypted, and finally encoded in base Unfortunately, we were unable to get any C2 servers to issue download commands to any samples that we tested in our lab.

Downeks can also be instructed to execute binaries that already exist on the victim machine. After successful execution, Downeks returns the results to the C2 server.

The filenames across the two variants bear striking similarities. This is a pseudo-unique ID for each machine, based on install date taken from the registry, volume serial number, OS version and service pack, Processor architecture, and computer name.

Downeks enumerates any antivirus products installed on the victim machine and transmits the list to the C2.

It constructs this list using the WMI query:. Downeks has static encryption keys hardcoded in the code. Notify me of followup comments via e-mail.

These four bytes are a CRC32 sum, and the malware then proceeds to brute force what 6-byte values will give this CRC32 sum. Once it finds this array of 6 bytes it performs an MD5 hash sum on the bytes, this value is used as the key.

The first 16bytes of the encrypted resource are then used as the IV for decryption Finally, using AES it decrypts the embedded resource.

A script mirroring this routine can be found in appendix C.
