Malware (Malicious Software) is any software intentionally designed to damage, disrupt, or gain unauthorized access to computer systems, networks, or data. It is a major cybersecurity threat used by attackers to steal information, spy on users, or cause system failures.
In cybersecurity, malware can infect devices through downloads, email attachments, unsafe websites, or infected software. Once installed, it can operate silently or cause visible damage depending on its type.
For example:
- A virus corrupts files and spreads to other systems.
- Ransomware locks a user’s data and demands payment to unlock it.
- Spyware secretly collects user activity and personal information.
- Trojans disguise themselves as legitimate software but perform harmful actions.
Common types and concepts related to malware include:
- Virus
