What does the notification with Win32/Injector.CXX detection mean?

The Win32/Injector.CXX detection you can see in the lower right corner is shown to you by Microsoft Defender. That anti-malware application is pretty good at scanning, but prone to be mainly unstable. It is unprotected to malware invasions, it has a glitchy interface and problematic malware clearing capabilities. For this reason, the pop-up which states concerning the Injector is simply a notification that Defender has found it. To remove it, you will likely need to make use of a separate anti-malware program.

Microsoft Defender: “Win32/Injector.CXX”

The exact Win32/Injector.CXX infection is a really nasty thing. It is present into your computer disguised as a part of something benevolent, or as a piece of the app you downloaded at a forum. Then, it makes all possible steps to weaken your system. At the end of this “party”, it injects other malicious things – ones which are wanted by crooks who manage this virus. Hence, it is impossible to predict the effects from Injector actions. And the unpredictability is one of the baddest things when it comes to malware. That’s why it is rather not to choose at all, and don’t give it even a single chance to complete its task.

Threat Behaviour

Click to expand
  • 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.
  • Injection (inter-process);
  • Injection (Process Hollowing);
  • 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.
  • Unconventionial language used in binary resources: Finnish;
  • Executed a process and injected code into it, probably while unpacking;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.

Is Win32/Injector.CXX dangerous?

As I have mentioned , non-harmful malware does not exist. And Win32/Injector.CXX is not an exception. This malware changes the system setups, modifies the Group Policies and registry. All of these things are vital for correct system functioning, even when we are not talking about system safety. Therefore, the virus which Injector contains, or which it will inject after some time, will squeeze out maximum profit from you. Crooks can steal your personal data, and then sell it at the black market. Using adware and browser hijacker functions, embedded in Win32/Injector.CXX virus, they can make profit by showing you the banners. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.

How did I get this virus?

It is not easy to trace the origins of malware on your PC. Nowadays, things are mixed, and distribution methods utilized by adware 5 years ago can be utilized by spyware nowadays. But if we abstract from the exact spreading way and will think about why it has success, the explanation will be really uncomplicated – low level of cybersecurity understanding. People click on promotions on weird sites, open the pop-ups they get in their web browsers, call the “Microsoft tech support” believing that the scary banner that states about malware is true. It is important to recognize what is legitimate – to prevent misconceptions when trying to find out a virus.

Nowadays, there are two of the most common tactics of malware spreading – lure emails and also injection into a hacked program. While the first one is not so easy to avoid – you should know a lot to understand a counterfeit – the 2nd one is very easy to handle: just do not utilize cracked apps. Torrent-trackers and other sources of “free” applications (which are, in fact, paid, but with a disabled license checking) are really a giveaway place of malware. And Win32/Injector.CXX is simply among them.
