Title: JasperLoader targets Europe with Gootkit banking trojan
Description: A loader known as “JasperLoader” has been increasingly active over the past few months and is currently being distributed via malicious spam campaigns primarily targeting central European countries, with a particular focus on Germany and Italy. JasperLoader employs a multi-stage infection process that features several obfuscation techniques that make analysis more difficult. It appears that this loader was designed with resiliency and flexibility in mind, as evidenced in later stages of the infection process.
