Security reports have appeared regarding a network vulnerability, identified as Ingreslock backdoor. Ingreslock is a legitimate service that locks parts of an Ingres database and uses TCP 1524 (Transmission Control Protocol). What is troublesome is that the 1524 port is often used by Trojans as a backdoor into a system.

What Is Ingres Database?
Ingres Database is a commercially supported, open-source SQL relational database management system that supports big commercial and government programs. Being open-source, Ingres Database has a large community of contributors. Actian Corporation, however, controls the development of Ingres and makes certified binaries available for download, and provides worldwide support.
Ingreslock Backdoor Technical Review
As already said, the Ingreslock port – 1524/TCP may be used as a backdoor by various programs, which may exploit RPC (remote procedure call) services. According to security experts, the Ingreslock backdoor may be used as an intentional backdoor by malicious actors to obtain access to a system. Malicious actors only need to connect to the port, and they will be logged in, having the same privileges as the user running the service.
A researcher has analyzed a unique attack carried out with the help of Ingreslock port 1524/TCP (for more details, click on the link). The analyzed rootkit that was installed during the malicious operation contained:
trojaned binaries, a couple of DoS tools, solaris patches, sshd backdoor, log cleaner, sniffer, file resizer, and a psy-bnc binary.
This set of tools could have been applied in various malicious operations, including targeted network attacks.
Backdoors, in general, are used to bypass regular authentication in software products and operating systems. When in the hands of malicious actors, backdoors are deployed to gain unauthorized access to a victim’s system. In the current state of cyber crime, backdoors are often used in ransomware attacks. Basically, if a backdoor is open to a system, any malware can enter at any time.
Apart from the attack scenarios described above, a McAfee user has reported seeing Chrome processes that show ports “ingreslock” and “pptp”. The interesting thing is the user says he doesn’t have Ingres Database installed:
I have Tcpview running from startup, and today I noticed something I’ve not seen before. Tcpview showed the local ports being used for two Chrome processes not as numbers but as “ingreslock” and “pptp”. I should have taken a screenshot, because after a couple of minutes – while I was busy Googling to find out what these new things were – the processes ended and vanished from the list.[…] Note, I do not have an Ingres database.
If you have witnessed a similar activity in any of your browsers, you should think of immediately scanning your system to make sure it isn’t compromised by a backdoor.
For now, there is no official explanation as to why these processes appear in systems that don’t have Ingres. We will keep you updated.
Ingreslock Backdoor TCP 1524 Mitigation and Removal
Besides running a full system scan, users who have suspicions that a backdoor has sneaked into their systems should lock down the TCP 1524 port at the firewall. The best way to fix this problem is to call your Internet provider, explain the issue and ask them to lock down the troublesome port for you.
Then, use a powerful anti-malware utility to determine whether your system is compromised or protected.

Preparation before removing Ingreslock Backdoor.
Before starting the actual removal process, we recommend that you do the following preparation steps.
- Make sure you have these instructions always open and in front of your eyes.
- Do a backup of all of your files, even if they could be damaged. You should back up your data with a cloud backup solution and insure your files against any type of loss, even from the most severe threats.
- Be patient as this could take a while.
- Scan for Malware
- Fix Registries
- Remove Virus Files
Step 1: Scan for Ingreslock Backdoor with SpyHunter Anti-Malware Tool
Step 2: Clean any registries, created by Ingreslock Backdoor on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Ingreslock Backdoor there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by Ingreslock Backdoor on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
