## 1 Types of Malware - **Viruses**: Infect executable files and spread when the infected file is executed. - **Worms**: Autonomous malware that replicates itself and spreads over networks, without depending on the execution of files. - **Trojan Horses**: Appear as legitimate software, but contain hidden malicious functions. - **Ransomware**: Blocks access to data or systems and demands payment of a ransom. - **Spyware/Adware**: Collects information from the system or displays advertisements without the user's consent. ##
C++ Language and Malware Although viruses can be written in various languages, C++ is a common choice due to its efficiency and low-level control of the system. An educational example of how a C++ program can modify the system would be the use of libraries such as WinAPI to manipulate processes and files, although this knowledge should be used to create protections. Here is a basic C++ example for manipulating files (a technique that could be used by malware, but here is used to understand how to protect the system): ```cpp #include #include #include int main() { std::string filename = "test.txt"; // Opening a file for writing std::ofstream outfile(filename); // Writing data outfile << "Example of file manipulation in C++" << std::endl; // Closing the file outfile.close(); // Opening the file for reading std::ifstream infile(filename); std::string content; // Reading the file content while (std::getline(infile, content)) { std::cout << content << std::endl; } infile.close(); return 0; } ``` ##
Defense against malware - **Antivirus and Antimalware**: Use protection software that scans for and eliminates known malware. - **Firewalls and IDS (Intrusion Detection Systems)**: Monitor network traffic and identify suspicious activity. - **Security Education and Practices**: Never download or run files from unknown sources; keep the system and software up to date.
