It is better to prevent, than repair and repent!
Most of the cases, Trojan.Win32.Bsymem ransomware will instruct its victims to start funds transfer for the purpose of reducing the effects of the modifications that the Trojan infection has actually presented to the target’s device.
These modifications can be as follows:
- 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.
- 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.
- A process attempted to delay the analysis task.;
- Attempts to connect to a dead IP:Port (7 unique times);
- At least one IP Address, Domain, or File Name was found in a crypto call;
- A process created a hidden window;
- 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.
- HTTP traffic contains suspicious features which may be indicative of malware related traffic;
- Performs some HTTP requests;
- Unconventionial language used in binary resources: Malay (Brunei Darussalam);
- The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Uses Windows utilities for basic functionality;
- Checks for the presence of known windows from debuggers and forensic tools;
- 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!
- Steals private information from local Internet browsers;
- Network activity contains more than one unique useragent.;
- 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:
- 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.
- Attempts to identify installed AV products by installation directory;
- Checks the CPU name from registry, possibly for anti-virtualization;
- Detects VirtualBox through the presence of a registry key;
- Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
- Attempts to create or modify system certificates;
- 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.
- Uses suspicious command line tools or Windows utilities;
- Ciphering the papers found on the sufferer’s hard disk — so the sufferer can no longer make use of the information;
- 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.
The most common channels whereby Trojan.Win32.Bsymem Trojans are infused are:
- By methods of phishing emails;
- As an effect of user ending up on a source that holds a destructive software application;
As soon as the Trojan is efficiently injected, it will certainly either cipher the information on the victim’s computer or avoid the tool from working in an appropriate manner – while also putting a ransom note that states the demand for the targets to impact the settlement for the objective of decrypting the files or bring back the file system back to the preliminary condition. In most instances, the ransom money note will come up when the client restarts the PC after the system has actually currently been damaged.
