A malware attack is a type of cybersecurity threat that involves malicious software infiltrating systems to cause harm or achieve unauthorized access to sensitive data. This can occur without the user's knowledge, as malware can operate in the background while the user continues their activities. Once the malware is active on a system, it can perform various actions, such as stealing data, corrupting files, or granting unauthorized access to attackers, all without any visible signs for the user.

In contrast, a ransomware attack typically requires the user to notice that their files have been encrypted and is generally more visible due to the demands for ransom that follow. A service level agreement (SLA) policy violation relates to contractual agreements rather than a direct cybersecurity threat impacting data integrity or confidentiality. Incomplete data input is an issue related to data management rather than a cybersecurity threat, as it does not involve malicious intent or unauthorized access to systems. Therefore, the unique characteristic of malware's stealthy operation makes it the correct answer to the question regarding cybersecurity threats that can lead to information being stolen or damaged without the user ever being aware.
