It started with the MBAM team discovering a forum thread at the IOBit forum with a user questioning the scan results from their new Security 360 product. The scan result is:
Dont.Steal.Our.Software.A, File, G:\Nothing Much\Anti-Spyware\Malwarebytes' Anti-Malware v1.39\Key_Generator.exe, 9-30501The definition classification of Don't.Steal.Our.Software.A. is the exact same one that Malwarebytes' uses in their virus definitions for various MBAM serial code generators. The MBAM staff found it strange that IOBit would detect MBAM keygens and at the same time use the classification that they themselves made up. This led them to become suspicious and to dig deeper into the IOBit virus definitions. What they discovered was that this was not a unique incident and that there were other definitions that were copied directly from their database as well.
To finally confirm that they were indeed stealing their definitions, MBAM created a definition for a fake and nonexistent Rogue program called Rogue.AVCleanSweepPro and created fake and harmless test files to go along with this test. This is not a real infection and was made up by the Malwarebytes' development team in order to catch IOBit in the act. Therefore, the only place this definition should exist is in the Malwarebytes program definitions. Within two weeks, though, IOBit was flagging this same infection under almost the exact same names. So let's recap. A company makes up a program and two weeks later it appears in another company's program? Seems pretty obvious that they are stealing their definitions.
Malwarebytes` has also stated that they have discovered that IOBit may have stolen definitions from other competitors databases as well. At this time we do not who these other competitors are and what was stolen. This is not the first time that malware definitions have been stolen from competitors, but no matter how you look at it, this is a criminal act as the virus definitions are the intellectual property of the creators.
After the announcement, there has been a strong community outcry on the purported behavior of IOBit as seen by the Malwarebytes's announcement topic listed below. As IOBit is located in China, there has not been much of a response back from them as of yet. The only thing we have seen are threads being deleted from the IOBit forums when the subject is broached, and just recently, and new thread created by a IOBit staff member that is supposed to be used to post questions about the accusations by Malwarebytes'.
We will continue to cover this and provide any updates as we get them.
