What is Win32/Injector.DOCR infection?
In this article you will discover regarding the definition of Win32/Injector.DOCR as well as its unfavorable influence on your computer. Such ransomware are a kind of malware that is clarified by on the internet frauds to demand paying the ransom by a victim.
It is better to prevent, than repair and repent!
Most of the instances, Win32/Injector.DOCR ransomware will advise its targets to start funds transfer for the objective of counteracting the changes that the Trojan infection has actually introduced to the sufferer’s device.
These adjustments can be as complies with:
- Executable code extraction. Cybercriminals often use binary packers to hinder the malicious code from reverse-engineered by malware analysts. A packer is a tool that compresses, encrypts, and modifies a malicious file’s format. Sometimes packers can be used for legitimate ends, for example, to protect a program against cracking or copying.
- At least one process apparently crashed during execution;
- Injection (inter-process);
- Injection (Process Hollowing);
- Injection with CreateRemoteThread in a remote process;
- Presents an Authenticode digital signature;
- Creates RWX memory. There is a security trick with memory regions that allows an attacker to fill a buffer with a shellcode and then execute it. Filling a buffer with shellcode isn’t a big deal, it’s just data. The problem arises when the attacker is able to control the instruction pointer (EIP), usually by corrupting a function’s stack frame using a stack-based buffer overflow, and then changing the flow of execution by assigning this pointer to the address of the shellcode.
- Starts servers listening on 127.0.0.1:32767, 127.0.0.1:32768;
- Reads data out of its own binary image. The trick that allows the malware to read data out of your computer’s memory.
Everything you run, type, or click on your computer goes through the memory. This includes passwords, bank account numbers, emails, and other confidential information. With this vulnerability, there is the potential for a malicious program to read that data.
- Drops a binary and executes it. Trojan-Downloader installs itself to the system and waits until an Internet connection becomes available to connect to a remote server or website in order to download additional malware onto the infected computer.
- The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Executed a process and injected code into it, probably while unpacking;
- Queries information on disks, possibly for anti-virtualization. Since VMs share the same disk space so it is expected that they won’t be getting as much space as an application running on
native hardware will have access to.
- Attempts to remove evidence of file being downloaded from the Internet;
- Crashed cuckoomon during analysis. Report this error to the Github repo.;
- A process attempted to delay the analysis task by a long amount of time.;
- Tries to unhook or modify Windows functions monitored by Cuckoo;
- Attempts to repeatedly call a single API many times in order to delay analysis time. This significantly complicates the work of the virus analyzer. Typical malware tactics!
- Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;
- Steals private information from local Internet browsers;
- Installs itself for autorun at Windows startup. There is simple tactic using the Windows startup folder located at:
C:\Users\[user-name]\AppData\Roaming\Microsoft\Windows\StartMenu\Programs\Startup. Shortcut links (.lnk extension) placed in this folder will cause Windows to launch the application each time [user-name] logs into Windows.
The registry run keys perform the same action, and can be located in different locations:
- Spoofs its process name and/or associated pathname to appear as a legitimate process;
- Creates a hidden or system file. The malware adds the hidden attribute to every file and folder on your system, so it appears as if everything has been deleted from your hard drive.
- Checks the system manufacturer, likely for anti-virtualization;
- Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;

- Creates a copy of itself;
- Harvests credentials from local FTP client softwares;
- Harvests information related to installed instant messenger clients;
- Harvests information related to installed mail clients;
- Creates a slightly modified copy of itself;
- Collects information to fingerprint the system. There are behavioral human characteristics that can be used to digitally identify a person to grant access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
- Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Ciphering the papers situated on the sufferer’s hard disk — so the target can no more use the data;
- Preventing routine accessibility to the target’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
One of the most common channels where Win32/Injector.DOCR Ransomware Trojans are infused are:
- By means of phishing e-mails;
- As an effect of user winding up on a resource that holds a malicious software;
As soon as the Trojan is efficiently injected, it will either cipher the information on the victim’s PC or avoid the device from functioning in a correct manner – while also putting a ransom money note that discusses the requirement for the sufferers to impact the repayment for the purpose of decrypting the documents or restoring the data system back to the initial problem. In a lot of instances, the ransom money note will come up when the client restarts the COMPUTER after the system has currently been damaged.
Win32/Injector.DOCR distribution channels.

Nevertheless, the ransom money notes and tricks of obtaining the ransom amount may differ relying on particular local (regional) settings. The ransom money notes and also techniques of obtaining the ransom quantity may vary depending on particular regional (regional) settings.

Faulty declarations regarding illegal web content.
In nations where software program piracy is much less prominent, this method is not as effective for the cyber frauds. Additionally, the Win32/Injector.DOCR popup alert might falsely declare to be originating from a police institution as well as will certainly report having situated kid pornography or other prohibited data on the gadget.
Win32/Injector.DOCR popup alert may falsely claim to be acquiring from a regulation enforcement establishment and will certainly report having situated youngster pornography or other illegal information on the tool.
