Trojan:Win32/Masson.A!ac Summary

These adjustments 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 (255 unique times);
• A process created a hidden window;
• 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;
• Attempts to delete volume shadow copies;
• 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!

Trojan:Win32/Masson.A!ac distribution methods

The biggest share of Trojan:Win32/Masson.A!ac virus distribution is after these methods:

Email spamming became a very popular 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 send by a cybercriminals has a strange sender address – something like f0138skbeu@gmail.com, while 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 kind of ads. However, if they are generated by adware which is 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 to 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.
