Credential harvesting malware refers to a category of malicious software specifically designed to steal login credentials, such as usernames and passwords, from unsuspecting victims. These credentials can then be used to access sensitive accounts, steal identities, or commit other types of fraud. Credential harvesting malware can take many forms, including keyloggers, screen scrapers, and phishing attacks.
Credential harvesting malware is a serious threat to businesses and individuals alike. According to a recent study, over 80% of data breaches involve the use of stolen credentials. This type of malware can cause significant financial losses, reputational damage, and identity theft. In some cases, it can even lead to legal liability.
There are a number of steps that businesses and individuals can take to protect themselves from credential harvesting malware. These include:
- Using strong passwords and two-factor authentication
- Being cautious of phishing emails and websites
- Keeping software up to date
- Using a reputable antivirus program
1. Keyloggers
Keyloggers are a type of credential harvesting malware that can be used to steal login credentials, passwords, and other sensitive information. They work by recording every keystroke that a user makes, including passwords and other sensitive information. This information can then be used to access sensitive accounts, steal identities, or commit other types of fraud.
-
How keyloggers work
Keyloggers can be installed on a computer or mobile device in a variety of ways, including through phishing emails, malicious websites, or drive-by downloads. Once installed, the keylogger will run in the background and record every keystroke that the user makes. This information is then sent to the attacker, who can use it to steal login credentials and other sensitive information. -
Types of keyloggers
There are a variety of different types of keyloggers, each with its own unique features and capabilities. Some of the most common types of keyloggers include:- Hardware keyloggers: These keyloggers are small devices that are attached to the keyboard or USB port. They record every keystroke that is made and store it on a internal memory chip.
- Software keyloggers: These keyloggers are software programs that are installed on the computer or mobile device. They record every keystroke that is made and store it on the hard drive or other storage device.
- Web-based keyloggers: These keyloggers are scripts that are embedded in websites. When a user visits a website that contains a web-based keylogger, the script will record every keystroke that the user makes on that website and send it to the attacker.
