What is Trojan:Win32/Wacatac.B!ml infection?
In this post you will certainly find about the definition of Trojan:Win32/Wacatac.B!ml and its adverse influence on your computer. That trojan virus is noted as a “preparing virus” for the further ransomware attack. DeathRansom ransomware is an example of ransomware that is distributed in pair with Wacatac.B!ml trojan
In the majority of the situations, Trojan:Win32/Wacatac.B!ml infection will not try to show its presence in your system. The more time that virus will be active, the more data it will steal from the user’s PC.
These modifications 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.
- 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 a shellcode isn’t a big deal. It’s just data. The problem arises when the attacker can control the instruction pointer (EIP), usually by corrupting a function’s stack frame using a stack-based buffer overflow and then changing the execution flow by assigning this pointer to the address of the shellcode.
- The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
- Network activity detected but not expressed in API logs. Microsoft built an API solution right into its Windows operating system. It reveals network activity for all apps and programs that ran on the computer in the past 30-days. This malware hides network activity.
- Changes in networking settings. The virus makes several additional entries in the HOSTS file and also modifies various registry keys.
Trojan:Win32/Wacatac.B!ml distribution methods
The biggest share of Trojan:Win32/Wacatac.B!ml virus distribution is after these methods:
Email spamming became a prevalent malware distribution method since the users do not raise suspicion on notifications from DHL or Amazon about the incoming delivery. However, it is quite easy to distinguish the malevolent email from the original one. One which is sent by cybercriminals has a strange sender address – something like firstname.lastname@example.org. At the same time, the original email address has a specific domain name (@amazon.com or @dhl.us) and can also be seen on the official website in the “Contact us” tab.
Malicious advertisements on the web, however, is an old-timer of malware distribution. And the advice to stop clicking the blinking advertisements on untrustworthy websites exists as long as the ads on the Internet. You can also install ad-blocking plugins for your web browser – they will deal with any ads. However, if they are generated by adware already present on your PC, ad blockers will be useless.
Software bundling is a widespread practice among the virus developers. Users who hack the programs to make them usable without purchasing a license approve any offer to include another program in the pack because they are gaining money in such a way. Check precisely the installation window for signs like “Advanced installation settings” or so. The ability to switch off the malware installation often hides under such items.
Signs of Trojan:Win32/Wacatac.B!ml presence.
In different edges of the world, victims of the Trojan:Win32/Wacatac.B!ml say about different signs of virus activity. Nonetheless, the common sign that your PC was infected is that its behavior differs from the one you used to.
Trojan:Win32/Wacatac.B!ml activity is quite hard to detect. And it is not a thing you need to wonder about – viruses like this one must stay undetected to be more effective and bring more effects. All changes it does are far away from the places where the user works. Group Policies, notifications settings, registry, Task Scheduler – these parts of the operating system are visited only when something goes wrong. And users get the fact that something is wrong only after the successful Wacatac activity.
It is quite hard to detect the changes done in registry and Group Policies because of the huge amount of entries in these system elements. But the notifications settings, and, especially, Task Scheduler, are elementary to control. If you see that the programs you are used to receiving notifications have stopped sending them to you or several programs added to the list, it is better to raise suspicion. The scheduler is a rare-used application, so if you had nothing scheduled and now see that something appeared in it, launch the anti-malware program.
