Verdict:	Malicious activity
Threats:	Mallox is a ransomware strain that emerged in 2021, known for its ability to encrypt files and target database servers using vulnerabilities like RDP. Often distributed through phishing campaigns and exploiting exposed SQL servers, it locks victims' data and demands a ransom. Mallox operates as a Ransomware-as-a-Service (RaaS), making it accessible to affiliates who use it to conduct attacks. Ransomware is a type of malicious software that locks users out of their system or data using different methods to force them to pay a ransom. Most often, such programs encrypt files on an infected machine and demand a fee to be paid in exchange for the decryption key. Additionally, such programs can be used to steal sensitive information from the compromised computer and even conduct DDoS attacks against affected organizations to pressure them into paying.
