In the majority of the instances, Trojan:Win32/Occamy.C hacktool will not show any signs of its presence. However, the user may notice the changes in the components he uses every day because this virus can’t make everything quiet.

Trojan:Win32/Occamy.C Summary

These modifications can be as adheres to:

• 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 flow of execution by assigning this pointer to the address of the shellcode.
• 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.
• Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.

Trojan:Win32/Occamy.C distribution ways

The majority of cases of Trojan:Win32/Occamy.C malware delivery goes to these ways:

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.

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 f0138skbeu@gmail.com. Simultaneously, 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.

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.

Making several complicated manipulations with the system security settings. The virus disables a visible security mechanism and turns off the methods used by the system to prevent malware execution. Under this term, I mean the forbid to launch the VBS scripts, disabled by default MS Office macroses or remote registry editing facilities.

Password extraction. Users who make use of a local Windows account may lose their credentials. The local account password is stored in a separate area of the Winlogon process in encrypted form. The virus may easily call the decrypt function and get the password of your account, as well as passwords of all users of your PC and local network.
