‘No Java Detected’ Pop-Up Alert

The ‘No Java Detected’ pop-up alert is a kind of attack that often is loaded by general CDN (Content Delivery Networks) like Rvzr-a.akamaihd.net. Unlike a real Java alert, the ‘No Java Detected’ pop-up alert may appear even for PCs who have settled the most recent version of Java already, and is meant strictly to install unwanted or threatening software. Because a ‘No Java Detected’ pop-up alert may include different payloads between different instances of its attacks, malware researchers must recommend general security strategies for dealing with the ‘No Java Detected’ pop-up alert, including the use of anti-malware programs to disinfect your PC after any encounters with this criminal pop-up.

When You Get a Little Something Added to Your Cup of Java


In a just world, a Java update warning would appear for PCs who only, truly require an update and would be associated with a redirect to an officially sanctioned download from Java.com. However, back in the real world, pop-ups like the ‘No Java Detected’ pop-up alerts are, just as often, used to attack the PCs of users who are interested in updating their software without considering the potential consequences. As malware experts have seen in previous attacks like the ‘Java Software Critical Update’ pop-up alert, the circumstances of these attacks are flexible, but may correspond to a fake media site pretending that some of its content has failed to load. This pretense then is followed by the launching of a ‘No Java Detected’ pop-up alert or similar pop-up, which claims that outdated or nonexistent Java is responsible for this issue.

There are two major ways by which the ‘No Java Detected’ pop-up alert differentiates itself from a legitimate Java update alert: in the first place, the fact that the ‘No Java Detected’ pop-up alert loads without any attempt to detect Java, and secondly that the ‘No Java Detected’ pop-up alert doesn’t install Java at all.
