An info stealer is a type of malicious software (malware) designed to extract sensitive information from infected devices. Common targets include login credentials, credit card numbers, banking information, and personal identification details.
Info stealers are often used in conjunction with phishing attacks, enabling cybercriminals to maximize the data they collect from victims.
How Info Stealers Work
Info stealers operate covertly, frequently evading detection by traditional antivirus solutions. They utilize a variety of techniques to gather sensitive data including keystroke logging, which involves recording the user’s keystrokes to capture passwords and other input.
This technique is commonly used by keyloggers, a specific type of malware that specializes in stealing credentials like passwords or login information and often acts as a precursor to more extensive
Screenshot capturing is another popular method, where snapshots of the user’s screen are taken to record sensitive information, along with file and system access, or directly extracting stored data from files or system directories.
Then, once the data is collected, it is often compiled into a stealer log—a detailed record of the stolen information. These logs are then transmitted to remote servers controlled by attackers, enabling them to exploit the data for financial gain, identity theft, or further cyberattacks.
RisePro Info Stealer
An example of a sophisticated info stealer is the RisePro Info Stealer. This malware is designed to stealthily extract sensitive data, including:
- Login credentials
- Banking details
- Personal identification information
RisePro exemplifies the evolving nature of info stealers, operating undetected and posing significant risks to both individuals and organizations. It highlights how cybercriminals leverage these tools to enhance phishing schemes and execute large-scale data breaches.

Info Stealers and Stealer Logs
As mentioned above, info stealers are closely associated with the concept of stealer logs, which serve as comprehensive records of the data harvested from infected systems.
Stealer logs can include:
- Passwords
- Credit card numbers
- Other sensitive information stored or entered on the device
These logs represent a critical threat in the cybersecurity landscape, as they are often sold or shared among cybercriminals to enable further exploitation or attacks.
The stealthy and efficient nature of info stealers makes them a potent tool in the arsenal of cybercriminals. Their ability to evade detection and extract valuable information underscores the importance of robust cybersecurity measures, such as advanced threat detection systems and employee awareness training, to mitigate these risks.
