Sub is a giant control subroutine containing a very large and ugly switch statement with cases:. There are buttons in this menu to manage the bridges, update data on victims, change builder settings and then interestingly buttons for support and help. Inside the pages served at these domains was the following code: The beginning of a PE file is pretty obvious in this snippet. Besides seeing that there appears to be a user-agent construction section within this subroutine, there are also a bunch of unlabeled calls in there. The delph1. GetWindowText the result of which is stored Sub 45D74C is used to identify the presence of services on the victim machine by the port that is in use. The support button actually gives us the following popup:. Uh, how about, stop writing malware?

Some apps or games will have checks when modifying so it will not allow modifications. It seems that the malware uses this to load and parse a PE header from a file probably the UPX-packed file we are discussing and then appears to use the code to then load a bunch of SQL Lite functions. S3curity RAT v0. The Bridge Taking a quick look at the. I found several sites hosting a page with the following appearance:. Based on this, it looks like the ransomware will search through fixed drives first, then removable likely USB drives next, followed by network drives. Static and Dynamic Analysis Taking a look at the stub. Ans In Android 4.

Sub CF0 is another subroutine that has been greatly filled in via the debugger. Prank RATs are generally not harmful, and won't log keystrokes or store information about the system on the computer. Many trojans and backdoors now have remote administration capabilities allowing an individual to control the victim's computer. IsWow64Process and determines the architecture based on the returned value. The other file, pd4ta. In doing some reading on the subject, this appears to be another way to detect certain sandbox environments. A final deadline can also be specified, which by default is four days. Within this switch statement, there are several cases that will pass the locations of stored credentials for the supported browsers and then call sub E60 to acquire them. You can use LocalBitcoins.

This way, by sending a malware to VirusTotal with small detection rates, you ensure that it will be highly detectable in a few days or even hours and will need to spend money on crypters. Keep in mind that, as the encryption key is kept out of the victim machine, brute force is really the only option. I should note that this particular copy of the builder was said to be cracked, and I noticed no network traffic related to this user creation process, so I suppose this is because of the crack or perhaps this is a local account set up on the Philadelphia builder. This change log gives us some idea of the pace of development of Philadelphia:. During our development, we used VirusCheckMate. The cases and associated functionality are as follows:. The default extensions to target are:. Sections of this page.

This is apparently a Darktrack 5. I went ahead and built a test Agent and Bridge. Darktrack 4. I have very little experience with AutoIT, but I would really like to see what else can be decoded from this file since this appears to be the actual script that handles the ransomware functionality in the client. Other evasion subroutines I found are as follows, with their associated product:. One subroutine that I am very interested in is sub 45A4EC. The encryption was done using a secret key that is now on our servers. Looking through the rest of the stuff revealed in memory suggests the following capabilities for Darktrack, though this needs to be confirmed by deeper digging:. Static and Dynamic Analysis Taking a look at the stub.

Right clicking on the connected Darktrack client reveals some options. Moving back over to the evasion subroutine beginning at AC, I set a new entry point to put us back in the various anti-analysis tests. Yes, we like to play with security, as you might have guessed. Running the stub. Pivoting off of whatever information I could find, it appears that the registrant of Join with us. The other file, pd4ta. This part of the Agent panel is where the settings for this feature can be specified.

Uh… yeah. One subroutine that I am very interested in is sub 45A4EC. Download Link 1. Sub C controls this. Socket based on the parameters being passed. So this is really something to ignore. Subroutine 45F looks like the overall system inventory sub. Yes, we like to play with security, as you might have guessed. Sections of this page. Sub is a giant control subroutine containing a very large and ugly switch statement with cases:.

At this point, the stack should just have the proc name on it. Definitively, you do not deserve congratulations for that. In the meantime, I suppose it would be possible to take the code from the malware, put it into some format of your choice, and use that to decypher traffic. We really recommend you to read every topic of this help file before your first adventure with Philadelphia. I took a class on hardware RE back in June , and it took me until now to actually get some basic equipment together like a power supply, microscope, etc. Once you open the card, you can see the rough outline of where some of the internals are — I tried to outline it a bit with a pencil Figure 2 :. The lack of a working client builder is a major issue, but this might have been an issue introduced by whoever cracked this particular copy of Darktrack. Once this was done, I was able to finish installation. Vestibulum sit amet sodales est, a lacinia ex.

None of those other domains are currently hosting anything. Do NOT turn off your machine. Please wait while we decrypt your files. I actually tried this just to be sure — I took the final encyphered text, put it where the plaintext should go, and watched as I ran the malware again and it decyphered what it had previously encyphered with this subroutine. Once you open the card, you can see the rough outline of where some of the internals are — I tried to outline it a bit with a pencil Figure 2 :. Sub C controls this. Right clicking on the connected Darktrack client reveals some options. When the breakpoint hit, I saw something very interesting which looks a lot like RAT C2 communication being used here:. You can also see the default password and host and

Speaking of the USB spreader, what I saw is that the ransomware drops an autorun. Looking through the rest of the stuff revealed in memory suggests the following capabilities for Darktrack, though this needs to be confirmed by deeper digging:. None of those other domains are currently hosting anything. The cases and associated functionality are as follows:. Given that the RAT has to use port and seems to like , one could be aware of strange traffic on these ports. Darktrack 4. I believe this is some sort of encryption subroutine. Ans The app needs to be opened once at least then it will automatically hide the icon.

This subroutine falls under case 0x61 in the main C2 subroutine and is also a switch statement with 15 cases. In the meantime, I suppose it would be possible to take the code from the malware, put it into some format of your choice, and use that to decypher traffic. The remote shell functionality is very easy to use, also. Secondly, never delete the Philadelphia files on a infected machine or make it impossible to run. If the user cannot open it, then there will be no way for recovering the files. When I ran it, this builder appeared to be clean. The cases and associated functionality are as follows:. GetTickCount to add this timing check to the other anti-analysis techniques. Opening this in Ida 5.

The operator controls the RAT through a network connection. After stepping through this subroutine and trying to keep things going in the right direction by modifying memory or the code, I was able to get the stub to connect to my panel: Right clicking on the connected Darktrack client reveals some options. I also found an evasion subroutine at F Perhaps the beginning was just copied and pasted from somewhere else. It then tries to start a remote thread in that notepad. I should note that this particular copy of the builder was said to be cracked, and I noticed no network traffic related to this user creation process, so I suppose this is because of the crack or perhaps this is a local account set up on the Philadelphia builder. Pretty easy to read it, but the p argument appears to be the action taken on the flat file; OS info shows the installed OS of the victim; user is the username of the victim on the infected machine; country is self explanatory; av appears to indicate the antivirus software if any ; locate shows character encoding on the victim machine; and finally the ucd argument appears to be the key. Do NOT turn off your machine.

See below from my debugger: Sub CF0 is another subroutine that has been greatly filled in via the debugger. It appears that this also allows the ransomware controller to specify which folders to attack first. Possible explanations include: — Someone is registering these domains and then hosting the malware themselves — These domains are being registered and then are used to host legitimate content, but someone compromises the sites to host the malicious file see this comment on VirusTotal for someone else putting this idea forward. I found this sample being hosted in the same way at a bunch of other sites, as well as what might be a Zeus sample: Ramnit fd6c69cf1ef0a5bbeba78d58e2cb03cedf 7team[.

With Stampado, we could be able to understand what ransomware buyers seek on new products. Once this was done, I was able to finish installation. How friendly it is. But DroidJack is a legit tool, why do we need to go to these lengths? Some flaws emerged from examining this sample. Perhaps notepad. There are a bunch of names to look into someday, plus also what appears to be the website for Darktrack at www. After pulling the UPX file out of the stub with Hiew, I unpacked it and it appears to just be a regular sqlite3.

With Stampado, we could be able to understand what ransomware buyers seek on new products. This is apparently a Darktrack 5. Good to know. This refers to the functionality in the ransomware that will help account for unforeseen transaction or other fees that might dip into the payment made by the victim and still count this payment as valid. At this point, the stack should just have the proc name on it. After stepping through this subroutine and trying to keep things going in the right direction by modifying memory or the code, I was able to get the stub to connect to my panel:. While, in a side, there is nothing we can do about it and any ransomware or encryption algorithm is vulnerable to it , in other side, there is also nothing to grant that the user is going to see the files back. I tried manipulating various things in sub CF0 which appears to be the subroutine to connect to the RAT host. IsDebuggerPresent and even a reference to SoftIce? Philadelphia takes all the hard work and presents to you a panel where you can take the control onto your hands.

Breaking News Loading Darktrack RAT has a nice user interface and contains a lot of functionality that would be of interest to a malicious actor. I noticed that the Darktrack builder appears to store victim information in a SQL Lite file, so maybe the developer just uses SQL Lite for storing the various information about victims both on the panel machine and on each victim machine. The delph1. Its primary function is for one computer operator to gain access to remote PCs. Looking at this, it seems fairly normal until you get to around k into the file, and then it looks like we have something there. Social Media. DroidJack is what you need for that.

I soldered a couple of wires to where the batteries hook up, then tried seeing what I could see at various connectors on the board trying to find a ground and anything else. So this is really something to ignore. Taking the case off reveals another four screws holding the circuit board in place, as well as what appears to be a rudimentary speaker all it seems to do is beep, such as when a button is pressed or at power on.
