Malware

The term malware (MALicious softWARE) refers to any program, document or message designed to harm a computing system.

What are the objectives of malware?

There are different types of malware, each with its threat level. Nevertheless, generally speaking, malware has the following objectives:

  • Provide an attacker with remote access to an infected computer.
  • Send spam from the infected computer to other systems.
  • Access the infected user's local network.
  • Steal sensitive information.

 

These are the most dangerous types of malware:

Scams: Trick users with fake travel promotions or winning lottery tickets, asking for money to provide access to the 'prize'.

Worms: Infect computers, slowing down networks and even blocking communications.

Phishing: Refers to creating fake websites to steal users' data and spoof their identities to, among other things, access their bank accounts.

Backdoor Trojans: Open a backdoor on compromised computers and let attackers take control of infected systems.

Keyloggers: Record, store and send keystrokes to attackers.

ATP (Advanced Persistent Threats): Enter infected computers for monitoring and control purposes, aiming to extract data on a continuous basis for corporate or political espionage.

Trojans: Install applications on infected computers, enabling attackers to take control of the affected system and its files and steal confidential information.

Exploits: Take advantage of security holes or vulnerabilities in communications protocols to enter computers.

Spyware: Gathers names, account details, passwords and, in general, any useful data from an organization.

Bots: Programs which, once installed on a computer, allow the attacker to take control of it remotely.

Ransomware: Blocks and takes control of computers, encrypting files and demanding a ransom to restore access to the system.
