Malware is malicious software designed to disrupt operations, gain unauthorized access, steal data, or establish persistent control over a system.
Attackers distribute malware through phishing attachments, malicious downloads, compromised websites, or exploited vulnerabilities, often using obfuscation to evade detection.
Malware enables attackers to spy, steal, disrupt, or move laterally within environments, frequently acting as the foundation for larger attacks such as data exfiltration or ransomware campaigns.
In 2025, cybersecurity researchers observed BlackLotus UEFI malware being used in targeted campaigns against enterprise and cloud environments. The malware infected systems at the firmware level, enabling stealthy persistence and evasion of traditional security controls. Attackers distributed it through compromised installers and malicious payloads, allowing them to maintain long-term access and execute further malicious activities without detection.
