Since mid-July 2015, I've noticed an increase in malicious spam (malspam) caught by my employer's spam filters with java archive (.jar file) attachments. These .jar files are most often identified as Adwind. Adwind is a Java-based remote access tool (RAT) used by malware authors to infect computers with backdoor access. There's no vulnerability involved. To infect a Windows computer, the user has to execute the malware by double-clicking on the .jar file. Of course, you have to have the Java Runtime Environment installed, which many people do. I previously associated Adwind with targeted phishing attempts in limited amounts. I had found very few examples of non-targeted malspam using this RAT.
