The group behind the Duqu cyberespionage tool has compromised at least two telecommunications operators and one electronic equipment manufacturer, in addition to a cybersecurity firm and venues that hosted high-level nuclear negotiations between world powers and Iran.
On Wednesday, Moscow-based antivirus firm Kaspersky Lab, which has been deeply involved in exposing sophisticated cyberespionage campaigns over the past few years, revealed that it too fell victim to such an attack.
