Flashpoint researchers have found that the monthly fee for the Rubella Macro Builder crimeware kit dropped to $40 on the underground market. Rubella was used as the first-stage loader by two criminal gangs in two recent but separate campaigns that used the Panda and Gootkit banking malware. The kit runs on Windows machines and does not utilize any vulnerabilities for its functionality. It can generate Microsoft Word (.DOC) and Microsoft Excel (.XLS) payloads. The macro can evade anti-virus software as well.”]
