RansomwareRansomware is a type of malware that encrypts a victim’s files or entire system, rendering them inaccessible. Attackers demand a ransom payment in exchange for a decryption key to restore access.
Trojan HorseTrojan horses are disguised as legitimate software but contain malicious code. They often trick users into downloading and installing them, allowing attackers to gain unauthorized access to the victim’s system.
SpywareSpyware secretly collects information about a user’s online activities, keystrokes, and personal data. It’s often used for stealing sensitive information or monitoring user behavior.
WormsWorms are self-replicating malware that spreads without human intervention. They exploit vulnerabilities in computer systems and networks to propagate, causing widespread infections.
BotnetsBotnets are networks of compromised computers (bots) controlled by a single entity. They are used to perform various malicious activities, such as launching DDoS attacks or distributing spam.
AdwareAdware displays unwanted advertisements to users. While not always inherently malicious, aggressive adware can negatively impact user experience and compromise privacy.
KeyloggersKeyloggers record keystrokes on a victim’s device, allowing attackers to capture sensitive information like passwords, credit card numbers, and personal messages.
Unwanted ApplicationsUnwanted applications are software programs that are often bundled with legitimate software downloads. They may lead to undesirable behaviors, such as displaying ads, collecting user data, or changing browser settings.
Browser HijackerBrowser hijackers modify browser settings without the user’s consent. They redirect users to malicious websites or unwanted search engines, causing inconvenience and potential security risks.
Coin MinersCoin miners, also known as cryptojacking malware, use the victim’s computer resources to mine cryptocurrencies without their knowledge. This can slow down the system and lead to increased energy consumption.
BackdoorBackdoors are hidden entry points created by attackers to gain unauthorized access to a system. They allow attackers to control the compromised system, steal data, or launch further attacks.
