Locky Ransomware Returns to Infect Windows XP and Vista

The deadly Locky RAnsomware is back once again but this time it seem like a half-baked effort from associated cyber-criminals as it is only targeting the older Windows versions namely XP and Vista only. It is being distributed through spam emails by the Necurs botnet. In early researches, there has been hint that the same Necurs botnet was also behind the Locky ransomware which was released last year and recently, the Jaff ransomare which is considered as a successor of Locky by many cyber-researchers. In recent times, Necurs has shown a shift to Jaff rather than locky.
