Detection Tool
See If Your System Has Been Affected by ServHelper Trojan
The ServHelper Trojan is an active backdoor malware which uses a very complex infection method to deliver another threat called “FlawedGrace”. The first instances of the attack campaign were identified back in November 2018 when the signs of its samples were detected.
The initial infection was done via a small-sized email phishing campaign which targeted financial institutions. They posed as internal communications, service notifications or other messages that were very likely to be opened by the recipients. Their will include attached documents of all popular formats: rich text documents, spreadsheets, databases and presentations. As soon as they are opened by the victims a prompt will appear asking them to enable the built-in scripts. This will lead to the payload delivery.
The next campaign targeted the retail industry with a combination of different attachments, namely “.doc”, “.pub”, or “.wiz”.
December 2018 saw another release of the ServHelper Trojan this time using a mix of various techniques — not only the phishing documents, but also PDF messages containing links to malicious sites described as “Adobe PDF plugins”. The body contents of the email messages can also contain direct links to the virus files. The PDF files that are being distributed coerce the users into believing that they need to download a new version of the Adobe Reader application in order to correctly view it. They are shown links to the dangerous strains.
This means that it is very possible for other delivery methods to be used as well:
Bundle Installers — The criminals can attempt to create setup files of popular software that contain the virus code. This is done by taking the legitimate files from their official sources and including the necessary instructions. Popular choices include system utilities, creativity suites, productivity and office apps and etc.
Malware Sites — The hackers can create phishing sites that imitate well-known download portals, product landing pages, search engines and others. They are made by using similar sounding domain names and security certificates that can be either self-signed or bought from certificate authorities using fake or stolen credentials.
Browser Hijackers — They represent malicious plugins that are made compatible with the most popular web browsers. These instances can mostly be found on the relevant repositories being posted with fake user reviews and developer information. The posted descriptions will promise feature additions and performance optimizations. At the same time as soon as they are installed important changes can occur to the browsers — the modification of settings such as the default home page, search engine and new tabs page. This is done in order to redirect the victims to a predesigned hacker-controlled page.
File-Sharing Networks — The files can also be shared on networks like BitTorrent where Internet users actively post both legitimate and pirate content.
As the campaigns progress further we anticipate that new phishing campaigns will be launched as the malware itself is updated.
ServHelper Trojan – Detailed Description
As soon as the ServHelper Trojan has infected the hosts it will launch a behavior pattern based on the current configuration. The main engine itself is written in Delphi which means that the source code can easily be modified between the iterations.
Almost all of them will instantly set up a local Trojan client allowing the attackers to set up a secure connection to their own servers. The “tunnel” version of the ServHelper Trojan will configure a reverse SSH tunnel. This means that the criminals will be able to use common Remote Desktop software in order to access the infected computers. As soon as this is done the malware engine will automatically analyze the system and locate all user accounts. They will be hijacked as well as any stored web browser credentials. This means that the ServHelper Trojan can access all important parameters of the most popular web browsers:
Cookies
Settings
Bookmarks
History
Stored Site Preferences
Stored Account Credentials
All known variants of the Trojan use port 443 which are used for HTTPS sessions and 80 which is for normal web server page delivery. From a network administrator’s perspective the compromised machines will send legitimate traffic as some remote desktop applications can route the traffic via these ports.
Most of the hacker-controlled servers are located on “.pw” top-level domains which can be a warning sign for administrators. Some of the later versions also feature some top-level domains of the “.bit” type which are also associated with the Namecoin cryptocurrency.
The POST information contained in the command and control servers have been found to signal encoded parameters: “key” which represents the ID of the threat which is hardcoded in each separate virus version. The “sysid” parameter will show the unique ID which is generated for every different host. The captured samples use an algorithm that uses the following data as input values: campaign ID, Windows version, System architecture, username and a random integer. A third parameter called “resp” contains the responses from the hacker controllers.
A list of all available commands that have been captured from the live network analysis reveals the following arsenal:
nop — This will enable a keep-alive functionality which will constantly probe the network connection in order to keep it running.
tun — This will set up a tunnel connection from the compromised hosts originating from the RDP port (3389). Some of the captured samples have been found to run an extensive array of commands. They will extract and drop and OpenSSH binary, configure the local RDP Warapper Library Software and create an associated username called “supportaccount” with a preset password of “Ghar4f5”. This user will be added to the “Remote Desktop Users” and “Administrators” groups. Later versions will replace this third-party app with the built-in Windows remote desktop application.
slp — This will set a hacker-defined sleep timeout.
fox — This will instruct the local instance to copy the Mozilla Firefox user profile.
chrome — This will do the same for Google Chrome.
killtun — This will kill an active SSH tunnel process.
tunlist — This command will list all active SSH tunnels.
killalltuns — Kills all SSH tunnel processes.
shell — This will execute a given shell command and send the response to the active C&C server.
load — This command will download and run an executable from a specific URl. The output will be reported to the hacker-controlled server.
socks — This will create a reverse SSH tunnel which is to be run between the C&C server and other clients.
selfkill — This will remove the active malware from the infected machines.
loaddll — This is very similar to “load” but for DLL files.
bk — This will set the reverse SSH tunnel to use a C&C specified remote host instead of the hardcoded server.
hijack — This command will hijack a given user account with a known person. This is done by creating a preset batch file that will interact with the Windows Registry and Scheduled tasks service.
forcekill — This will kill all processes using the Windows “taskkill” command.
sethijack — This will control a built-in “alert” mechanism. This is done by a separate program which monitors the user login events. When a legitimate user logs a built-in behavior pattern will automatically start: the “chrome” and “fox” commands will be run, the profiles will be copied to the “supportaccount” user and alerting the hacker controllers.
chromeport — This implements the same functionality as “chrome”. This will also lead to the “FlawedGrace” malware delivery.
Most of the ServHelper Trojan aim to deliver the FlawedGrace RAT. It is a payload that is delivered through the Trojan which acts as a dropper. As soon as it is launched a built-in behavior pattern will be started. It will create, encrypt and store a configuration file that contains information about the hacker-controlled server. The FlawedGrace RAT uses a separate binary protocol for communications and it can use a different port for communication as defined by its controllers. The default one is 443.
A list of the commands that have been identified from a network analysis is the following:
The fact that the ServHelper Trojan and the associated FlawedGrace RAT are bundled together in most of the attack campaigns shows that the threat actor behind it is experienced. All delivery campaigns so far target companies and not individual users. We anticipate that future versions will be developed having an even more dangerous arsenal of malicious actions.

4. Try to Restore files encrypted by ServHelper Trojan
Try to Restore Files Encrypted by ServHelper Trojan
Ransomware infections and ServHelper Trojan aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
