Duqu

Duqu is a sophisticated form of malicious software (malware) that was discovered around 2011. It is designed to spy on organizations by collecting sensitive information and possibly gathering data to help with future cyberattacks. Unlike typical viruses, Duqu uses advanced techniques to remain hidden and avoid detection. It often targets corporate networks to steal information such as intellectual property, credentials, or strategic data. Think of it as a highly skilled digital spy that infiltrates systems quietly, sneaks around collecting information, and then leaves without obvious signs of damage, making it a serious threat to cybersecurity.
