Duqu history
Duqu was first discovered in 2011. Its discovery sent shockwaves through the cybersecurity community due to its connection to the infamous Stuxnet worm, which targeted Iran’s nuclear program. Named Duqu after the .DQ file extension it used, this malware was found to possess advanced capabilities such as evading detection due to its modular nature.
Duqu is closely intertwined with Stuxnet. It shared similarities in its code and attack methods, indicating a possible common origin or collaboration. Like Stuxnet, Duqu was designed for targeted espionage, focusing on gathering sensitive information rather than causing immediate disruption or damage to systems.
Duqu primarily infiltrated systems through spear-phishing emails or by exploiting vulnerabilities in software. Once inside a network, it spread laterally to other systems, aiming to establish persistence and expand its reach.
The last reported activities and variants of Duqu were observed in 2012. Since then, there have been no significant reports or indications of active campaigns or new versions of Duqu. However, as the ever-evolving cybersecurity landscape suggests, companies should stay vigilant because Duqu or similar malware can emerge again.
