Mal/JavaKnE-H Description

Mal/JavaKnE-H is a malicious Java applet that's used to install Trojans (such as the recently-identified Dropper.MsPMs and Troj/Agent-XNE). If you have Java enabled in your browser, visiting a site that hosts Mal/JavaKnE-H results in automatic attacks against your PC, and even updating Java isn't an adequate defense – since Mal/JavaKnE-H's exploit hasn't had a corresponding patch to remedy this security flaw. malware researchers have been unable to find any symptoms related to Mal/JavaKnE-H's attack, which is hosted on the domain Trojans that are installed by Mal/JavaKnE-H are potentially high-level security threats, and you should remove such PC threats as soon as you can analyze your machine with anti-malware software whenever you suspect any contact with Mal/JavaKnE-H.

Why Mal/JavaKnE-H May Strike Despite All of Your Precautions

Mal/JavaKnE-H loads on malicious or hacked sites as a Java applet without visible symptoms – and with a Trojan payload that resolves itself as Troj/Agent-XNE. You should always scan your PC with anti-malware software after any potential contact with Mal/JavaKnE-H-hosting websites, and malware research team additionally encourages you to disable Java routinely whenever it's not required by a trustworthy site. Mal/JavaKnE-H's Java exploit (which shouldn't be confused with JavaScript-based ones) launches automatically unless you have other security measures enabled – such as anti-malware programs that can detect Mal/JavaKnE-H or its current website, Cxweb/BadDlod-G.

Java versions JRE 1.7x are all vulnerable to Mal/JavaKnE-H's exploit, and, if Oracle keeps to its usual patching cycle, will not receive security patches for Mal/JavaKnE-H until October this year. malware experts also note that Mal/JavaKnE-H has compatibility with multiple web browsers, although, as far as operating systems are concerned, Mal/JavaKnE-H appears to be limited to Windows (so far).

Mal/JavaKnE-H's sole purpose is to install malicious software onto your PC, and you should consider your PC potentially infected after any possible exposure to a Mal/JavaKnE-H-hosting site – or even advertisement.

Where Mal/JavaKnE-H Goes from Here

Mal/JavaKnE-H's Java exploit has been recently made public and, as a consequence, is very likely to be included in other attacks in the future – such as BEK or Blacole attacks that are configurable to deliver many types of PC threats across many platforms. Current Mal/JavaKnE-H payloads are focused on delivering backdoor Trojans that are capable of granting access to your PC to remote attackers. Consequences of such security breaches can include:

  • The installation of other PC threats on your hard drive.
  • Security programs (Task Manager, anti-virus scanners) being disabled.
  • Security features that are changed to be inactive – usually via the Windows Registry. For example, Trojans installed by Mal/JavaKnE-H may change Internet Explorer's security zones to make web-browsing unsafe.
  • Loss of confidential information due to spyware-related attacks or direct access to the relevant information through the associated backdoor Trojan.
