Malware Analysis of Remcos RAT: Exploitaion and Detection ExplainedExecutive SummarySHA256 hash:2e5c4d023167875977767da513d8889f1fc09fb18fdadfd95c66a6a890b5ca3fRemcos is a commercially available Remote Access Tool (RAT) marketed for legitimate use in surveillance and penetration testing. However, it has been leveraged in various unauthorized hacking initiatives. When deployed, Remcos establishes a backdoor, allowing comprehensive remote control over the affected system. The tool is a product of BreakingSecurity, a company specializing in cybersecurity solutions.Hackers are getting smarter by using tricks like hiding their code and adding fake code, which makes it harder for security experts to figure out how their attacks work. They're using things like image files and compression to disguise their activities.YARA signature rules are attached in Appendix A. Malware sample and hashes have been submitted to VirusTotal for further examination.High-Level Technical SummaryRemcos is an advanced remote access tool that breaks into computers using a series of hidden codes, starting with a malicious file which can be delivered from mail or dropper. It cleverly disguises its next steps within an image file, and then uses another DLL to make sure it stays on the computer even after it's restarted. Remcos can record keystrokes to steal passwords and other private information, which it logs into a file. It stays in contact with the hacker's server to send out this stolen information and to get new orders, allowing the hacker to keep a close watch and control over the infected computer.Malware CompositionThis composition of remcos consists of the following components:2e5c4d023167875977767da513d8889f1fc09fb18fdadfd95c66a6a890b5ca3fEmbedded_Remcos.exeIn a C# dropper, there's a sneaky way that malware developers are hiding bad code. They put this code inside the InitializeComponent() method. This method is normally used just for setting up how the app looks, like buttons and menus. But now, it's being used to hide something harmful. The tricky part is that this bad code looks just like regular setup code, so it's hard to spot. It's like hiding something bad inside something good, so people don't notice it.This makes it hard to find and fix the problem. It's a clever trick by hackers, and it shows how they can use parts of an app we usually trust to do sneaky things.It is extracting a byte array from a resource, possibly a file or other data embedded in the application and generating another byte array from a hard coded string.The code is setting up a user interface for a form and then performing an operation on a data resource (“SHP”) using a generated key.The _data before the encryption looks like this.The for loop processes the Data_ array in a complex way. It goes through each byte of Data_ and modifies it based on a calculation involving both Data_ and KeyGen.The calculation inside the loop involves bitwise XOR (^), addition, and modulo operations. It appears to be some form of data manipulation or encryption/decryption, where Data_ is being altered using the KeyGen byte array.First, a MethodBase object named methodBase is assigned the value kb. The MethodBase class in C# is part of the reflection namespace and is used to discover information about methods (like constructors and other methods) at runtime.Then, an array of objects named array is created and initialized with string values. This array includes this.VC, this.VR, and the literal string “Boilerplate”. VC and VR are private string fields of the class, initialized to “57775972” and “6C7978”, respectively. Therefore, the array contains these two strings along with “Boilerplate”.Finally, the Invoke method on methodBase is called, passing obj and array as arguments. This means the method represented by methodBase is being executed with obj as the target and the string array as the parameters.Before the inoke there was binary loaded successfully in modules.And if look closely it in kb.Fullname it is calling dr,hA.wP method in Ben dll.Ben DLLBy adding breakpoint after loading from module we catch the debugger.The code performs image processing, uses reflection to invoke a method, and dynamically loads an assembly from a byte array. This kind of operation is typical in applications that need to manipulate images, dynamically execute code, and potentially load plugins or modules at runtime.Sleep for 16secnew MemoryStream(array2): This creates a new MemoryStream object using array2 as its buffer. array2 is assumed to be a byte array (byte[]) that contains data compressed using the GZip algorithm. The MemoryStream is a stream based on a memory buffer, allowing for reading from and writing to memory.new GZipStream(…): This creates a new GZipStream object. The GZipStream class is used to compress and decompress data in the GZip data format. In this case, it's constructed with the previously created MemoryStream and the CompressionMode.Decompress. This indicates that the GZipStream should be used for decompression, i.e., to decompress the data contained in array2.It's part of a process involving dynamic loading and reflection. It reads and possibly processes data from a MemoryStream, uses that data to load an assembly or access its contents, and then retrieves a specific type from that assembly.Rd is designed to dynamically load a .NET assembly from a byte array, denoted as u0020. It employs a nested, infinite loop structure with a switch statement for control flow. Initially, it attempts to load the assembly using Assembly.Load(u0020). The code's flow is influenced by the result of global::dr.hA.EV(), a method call whose purpose is unclear. If EV() returns a non-null value, the method exits the loop prematurely via a go to statement. The method's coding style, characterized by unconventional variable naming and complex looping, suggests a potential for obfuscation, possibly to conceal the actual functionality or make reverse-engineering more challenging.ReactionDiffusionAfter loading assembly we get a new binary in modules with the name of ReactionDiffusion.Then it disposes the “memorystream” which means the work of the memory stream is done here. Probably it will now move on to the next binary.After that it also dispose the gzip stream which was used to get the binary.Now let's track where it would go next in ReactionDiffusion. If we investigate the object where it is pointing its type show us the destination namespace and class.Since there were no method calls from previous binary. So, we created break point at constructor at it hit exact on it.There was nothing useful in ReactionDiffusion there, maybe it was all decoy code. Let's see what next the Ben binary does, in case 8 it gets bitmap from resources.RS MethodThe RS method in C# is designed to retrieve a Bitmap image from resources using reflection and obfuscated code patterns. It starts by declaring a ResourceManager to access embedded resources, using a dynamically constructed resource name from the first-string parameter, u0020. This parameter, along with a similarly named second parameter, is used in a nested, infinite loop structure with a switch statement. Bitmap is obtained by the method global::dr.hA.rY, which likely extracts the image from the resources. The control flow includes checks with global::dr.hA.EV() and global::dr.hA.m3(), whose purposes are unclear, but they seem to influence the flow and decision-making within the method. The use of obfuscated names (like u0020) and complex control flow suggests an intent to mask the code's functionality or purpose.Loading the assembly from byte arrayIt defines a private static method named Rd that takes a byte array u0020 as its parameter.It initializes an integer variable num with the value 1.Inside an infinite loop (for (;;)), the code performs the following actions: a. It declares a variable num2 and assigns it the value of num. b. It enters another loop (for (;;)). c. Within the inner loop, there is a switch statement with two cases:Case 1:It attempts to load an assembly using Assembly.Load(u0020), where u0020 represents the byte array passed as a parameter to the method.If the assembly is successfully loaded, it sets num2 to 0.It then checks whether global::dr.hA.EV() is not null. If it's not null, the code proceeds to the Block_1 label.If global::dr.hA.EV() is null, it effectively exits the loop and returns the loaded assembly.Default case:If none of the cases match, it returns the assembly variable, which would have been assigned earlier in the code. d. The Block_1 label is used to indicate the point where the code should continue if global::dr.hA.EV() is not null. It doesn't contain any specific code logic in the provided snippet.TyroneIt looks like another binary is coming. Another DLL loaded in modules with the name Tyrone.Invoking AJBqklj3Jn from tyorne { YcMqTyPiynJnoycycL.MhMHeAYqAZ6AJWSu3o}This is more obfuscated than previous binaries.Checking for the presence of a named mutex, which may be used by malware for synchronization or coordination purposes. “wnmJOXavioKPdkNYG”It tried to open but since if there is no mutex it goes to exception. If it exists it will end itself in second line.Creating MutexIt creates a new Mutex object with the name “wnmJOXavioKPdkNYG”. Mutexes are synchronization primitives used to control access to shared resources among multiple threads or processes.This was all to get path of appdata and then append it with “EiHjExP.exe”.“C:UsersusernameAppDataRoamingEiHjExP.exe”Check if not there Copy it.Change Directory PermissionIt adds access control entries to the directorySecurity object using the MhMHeAYqAZ6AJWSu3o.PR6qMi9p2U method. These entries seem to define permissions for specific file system rights (e.g., Read, ReadAndExecute, Delete, Write, etc.) with different access control types (e.g., Allow, Deny). The permissions are set for various inheritance flags and propagation flags, which determine how permissions are inherited by child objects.It removes “currentuser” security to change file and write permission.As you can see the permission are denied nowRemcos is doing this because it makes it safe from being changed or deleted from disc.Then it gets a base64 encoded text fetched from modules of this tyrone binary with this code.I decode this string from https://www.base64decode.org/ and it turns out that it is xml.There is code for decoding also in the remcos.Then this function is called to play with Microsoft Security. This function decodes the text which was fetched from module.It then creates a new process, assign a new stratinfo with it and give file name “powershell” which it gets from the module. In arguments of process, it gives @”Add-MpPreference -ExclusionPath “”C:UsersshaddyAppDataRoamingEiHjExP.exe”””Set process's window hidden.Windows ExclusionIt will be added to the exclusion but keep in mind that I was running it from admin, if not performing analysis from admin it will be able to add since so far there was not privilege escalation performed.Path.GetTempFileName(); it will return a string that represents a unique temporary file name. This file name is generated using a combination of a temporary directory path and a unique identifier, making it highly unlikely to clash with other temporary files in the system.It gets the identity of current user, exe path to update the xml. In the breakpoint it is updating the xml and saving it in text variable.The clean xml code.PersistenceAfter that it is writing all xml in tmp file.It then loads the command of scheduling task from modules and sets startupinfo of process. Process is executed with window style hidden, Filename “schtask.exe” and with following arguments.@”/Create /TN “”UpdatesEiHjExP”” /XML “”C:UsersshaddyAppDataLocalTemptmp66E3.tmp”””This command appears to be creating a new scheduled task with the name “UpdatesEiHjExP” and configuring it using an XML file located at “C:UsersshaddyAppDataLocalTemptmp66E3.tmp.”It is triggering the exe after every system restarts.Then it deletes the tmp file.After that it loads new assembly “xF7siMsac” from its resource manager.It is injecting this final binary and executing it. Let's see its injection inside process hacker.Another binary which is extracted and DE obfuscated from resources.Remcos / 5thstageAfter saving the binary from u0020 it looks exactly like client agent built from the original remcos agent from hxxps://breakingsecurity.net/remcos/. The logo is also the same, but its signature was not present in any online threat intelligence.https://www.virustotal.com/gui/search/f55fc4f4e1bcbe957d20750f56cd98869c717c18c14c8b6d42698557b254ad51This final stage was developed in c++ language. And before analysis when we perform strings filter there was something linking to remcos, this pattern comes almost in every remcos rat.Now let's start the debugger to look more into it. We can see some more identifications.It starts with calling GetAddrInfoW API which is pointing to rungmotors20.ddns.net:60247.GetAddrInfoW is a Windows API function that is used for network operations. It's part of the Windows Sockets (Winsock) API and is typically called to resolve network addresses or to perform name resolution, converting a hostname like a domain or a URL into an IP address that can be used to establish network connections.If running from admin privileges, it creates a directory [C:\ProgramData\remcos] using CreateDirectoryW API.CreateDirectoryW is a function in the Windows API that is used to create a new directory. The W at the end of CreateDirectoryW indicates that this function uses wide characters (Unicode), as opposed to CreateDirectoryA, which uses ANSI characters.After creating Directory, it creates file with name logs.dat using CretaeFileW api.There are privileges check also it is handling both cases smoothly. It is just paths which it used separately.While executed from admin it uses [ C:\ProgramData\remcos folder]. It creates thread and that thread in loop performs these steps.If executed from normal permission, it uses [C:\Users\username\Local\VirtualStore\ProgramData\remcos\logs.dat]It sets its mark on the system in registry. It sets exepath, licence and time for thread.Patching TLSAll traffic was encrypted so we must check what is being sent. There was TLS check which was on in our client rate.Since we cannot see what it is sending to server, because of TLS flag is on. It will send all the traffic encrypted. After patching this, we can analyze the traffic.After finding the check I was able to turn off the TLS and see all the traffic clearly. It was sending the device identification after every few seconds to server.This was sample data that rat was sending.$ KRemoteHost||DESKTOP-002IHON/shaddy||US||Windows 10 Enterprise (64 bit)||||8588939264||4.9.2 Pro||C:ProgramDataremcoslogs.dat||C:UsersshaddyDesktop5thstage.exe||||5thstage.exe — PID: 3308 — Module: 5thstage.exe — Thread: Main Thread 6232 — x32dbg [Elevated]||1||47||48556593||1||rungmotors20.ddns.net||Rmc-ZT6SIL||0||C:UsersshaddyDesktop5thstage.exe||12th Gen Intel(R) Core(TM) i7–12700KF||Exe||||Clipboard and Process recordingInside the thread it was performing three major activities because the one who built it, he/she only want to record clipboards, records keylogging and setting some registries.

Photo by Beth Jnr on UnsplashIn both the offensive and defensive penetration testing , grabbing a banner is the first and, it seems, the most crucial step. This post will introduce you to the concept of “Banner Grabbing” and explain how various web interfaces and command-line tools may be used to capture a webserver's banner along with its active services.Introduction“Banner Grabbing” is often termed as “Service Fingerprinting”.Banner refers to a text message received from the host, usually, it includes information about the open ports and services with their version numbers.Why Banner Grabbing?Banner Grabbing allows an attacker to discover network hosts and running services with their versions on the open ports and moreover operating systems so that he can exploit the remote host server.Banner Disclosure is the most common vulnerability with a “CWE-200 i.e. Exposure of Sensitive Information to an Unauthorized Actor” and a “CVSS Score of 5.0 with the Risk factor as Medium.”In order to clear the vision, we'll consider an attack scenario:As we all know that Microsoft Windows 7 are exploitable by Eternal Blue (CVE-2017–0143) directly with SMBv1 service. In order to enumerate this server, the attacker needs to grabs a service banner which displays whether the SMB service with a vulnerable version is running over it or not. If running, he/she can easily exploit the Microsoft server directly with the Eternal Blue attack.Types of Banner GrabbingActive Banner grabbing –In this, the attacker craft or modify his/her own packets and send them to the remote host server and analyses the response data in order to get the operating system information and the services running with their versions.Passive Banner grabbing –Here the attacker collecting data about our target using publically available information i.e. by analyzing the server either with the help of “Error Messages” or by “Sniffing up the Network Traffic”.Up till now, you might have gained a lot of information about what is Banner Grabbing and why it is used?Let's continue this journey by exploring the most aggressive and direct methods of grabbing a service banner.Banner grabbing using Kali LinuxWhatweb“WhatWeb” recognizes websites, which helps us to grab the web-applications banner by disclosing the server information with its version, the IP address, the webpage Title and running operating system.Type the following command in order to capture the essentials.whatweb <website URL>whatweb http://192.168.0.11cURLThe cURL command includes the functionality for retrieving the banner details from HTTP servers. Just execute the following command, and discover what we grab:curl –s –I 192.168.0.11However to fetch a clean result, we are using the -s flag to prevent the progress of the error messages from being displayed, and the -I flag to simply print out the header information of all requested pages.WgetWe will be using the wget command to capture the HTTP banner of the remote server.wget –q –S 192.168.0.11The –q flag will cover-up the progress of our output, while the -S flag will print out the header information of all requested pages.TelnetWe will be using the Telnet protocol in order to interact with services to grab their banners.Type following command to grab the FTP banner of the remote server.telnet 192.168.0.11 21As a result, it will dumb “220 (vsFTPd 3.0.3)”NetcatNetcat is a network utility that will again help us to grab the FTP banner of the remote host server.nc 192.168.0.11 21From the above image, you can check that it dumbs up “220 (vsFTPd 3.0.3)”NiktoNikto is an open-source web-application scanner, which we'll be using to grab a banner of a website running on an Ubuntu server.Type the following command in order to capture the installed web server — its version, the configuration index files, the HTTP server options and a list of other useful details.nikto –h http://192.168.0.11The –h flag is used to specify the host.NmapWe'll use Nmap as a simple banner grabber which connects to an open TCP port and prints out anything sent by the listening service within a couple of secondsType following command which will grab banner for the SSH service running on port 22 in the remote host.nmap -sV –p22 192.168.0.11The -sV flag prints out the version of the running service.From the above screenshot, you can read the SSH service and its version, fetched by NMAP as “OpenSSH 7.6p1 Ubuntu 4ubuntu0.3”DmitryDmitry (Deepmagic Information Gathering Tool) has the ability to gather as much information as possible about a host. Base functionality is able to gather possible subdomains, email addresses, uptime information, tcp port scan, whois lookups, and many more.The –pb flag is used to grab the banner for all the open-ports of the remote host.Fire the following command to grab the banners of the running services.dmitry –pb 192.168.0.11Banner Grabbing over BurpsuiteWhile performing an attack or a penetration test, we all use burp suite somewhere or the other, but does it help us to identify the target's web server?Yes, we can simply grab the server's information through the response generated by the repeater.From the below screenshot you can see that I've sent the interpreted request into the repeater. As soon as I hit the send button, the response will be executed and on the right-hand side you will get the captured server details as Apache/2.4.29 (Ubuntu)Banner Grabbing using NetcraftNetcraft is one of the most operatable information gathering web-interface which help us to check the technologies and the infrastructure of the web-applications.So I'll be using a demo website over Netcraft in order to grab some service banners and capture all the possible information.From the above image, you can see that I have grabbed the Hosting History of testphp.vulnweb.com, which shows up the IP addresses, the operating systems and the webservers along with their last seen.Banner Grabbing through Browser ExtensionsSometimes it's a bit time consuming while grabbing banners of multiple web applications. Thus in order to make our work faster, we will be setting up some browser extensions that will help us to capture the server information with their version numbers, the running operating systems and the other frameworks that drive up the web applications.WappalyzerWappalyzer is a free browser extension available for both Mozilla Firefox and Google Chrome.
