Six new cases of the malware Narilam have been detected in the last month.
The worm is designed to attack databases by modifying and deleting existing information. Unlike many malwares, the aim is purely to sabotage and not to replicate or steal. The malware is most likely to be an attack from one small to medium business on another competitor.
The malware was first detected in 2009 and effects computers operating Windows 7, Vista, XP and Windows Server 2008. The majority of cases have occurred in the middle east but a few cases have erupted in the UK and the USA.
