What is LummaC2 Stealer

LummaC2 Stealer, also known as Lumma Stealer or LummaC2, is a malicious program classified as an information stealer. It is written in the C programming language and is known for targeting cryptocurrency wallets, browser extensions, and two-factor authentication (2FA) mechanisms to steal sensitive information from victims’ machines. This malware has been sold on underground forums since December 2022 and operates under a Malware-as-a-Service (MaaS) model, making it accessible to a wide range of cybercriminals. The stealer is lightweight, approximately 150-200 KB in size, and can infect operating systems from Windows 7 to Windows 11. It is capable of collecting a variety of data, including passwords, credit card numbers, bank accounts, and other personal information. LummaC2 can also take screenshots of users’ desktops or active windows without their knowledge. It is important to note that the removal process can be complex due to the malware’s evasion techniques and the potential for additional payloads delivered by the stealer.
