\"\"The new JavaJar-B Trojan horse was discovered a few short days ago. This new malware has, thus far, only been found exploiting Oracle\u2019s update to Java, and only affects the newest version of runtime.<\/p>\n

Sophos, a security company that excels in finding malware and viruses that exploit computer systems, has described the new exploit as a \u201czero-day attack,\u201d which means that the Trojan was able to infect computers before anyone had a chance to investigate it and fix the problem. Not even Sophos is sure how to describe this vulnerability, but they included this information in its entry in the National Vulnerability Database:<\/p>\n

“Unspecified vulnerability in Oracle Java 7 Update 10 and earlier allows remote attackers to execute arbitrary code via unknown vectors, possibly related to “permissions of certain Java classes,” as exploited in the wild in January 2013, and as demonstrated by Blackhole and Nuclear Pack.”<\/p>\n

The Trojan has not been seen on Apple machines, though Linux and Windows have both seen their fair share of JavaJar-B. However, Apple products are expected to see this virus soon, as it is being distributed in Blackhole and Nuclear Packs, two hacker kits designed to exploit weaknesses in different operating systems.<\/p>\n

Fortunately, if you\u2019ve downloaded Java 7 already, you can take several steps to help secure your computer.<\/p>\n

    \n
  1. Go to the Java Control Panel.<\/li>\n
  2. In the Security section, uncheck \u201cEnable Java content in the browser.\u201d Your browser plug-in will be disabled.<\/li>\n
  3. This single action will prevent any unwanted execution of exploits that could happen as you wander around the Internet.<\/li>\n
  4. Then, change your security level in the same Security panel. Increase it from the default system of \u201cMedium\u201d to \u201cHigh\u201d or \u201cVery High\u201d. The high level will require approval each and every time unsigned Java code asks to run.<\/li>\n<\/ol>\n

    <\/a>If you do not have Java installed, then this Trojan cannot and will not affect your computer.<\/p>\n
