“Wsearch.net/?unknown” Is it a new DNSChanger?

As mentioned in my previous post, there has been a report about browser hijacking. However, as days goes by more and more Mac OS X users shares the same experience.

Unfortunately, this site serves unwanted pop-ups (Ads) although no malwares yet found.

So what’s happening here ?

1st of June, MozillaZine Forum user reported this incident and found his DNS search domain was set to “mygateway.net”. From the thread, they suspected that it was coming from the ISP (Rogers Cable).

A month after, another MozillaZine Forum user feels that the issue covers 3 possible source: 1) Zlob DNSChanger 2) DNS hijacking caused by SMC wireless routers 3) Rogers “service” hijacking URL searches

As more and more user experiencing this issue, I wonder if this is indeed related to Zlob’s DNSChanger. Unless someone can provide a DMG or URL for analysis, we can’t conclude this incident as new DNSChanger related activity.

    This is problem with SMC wireless router/modems. I am an Interent Support Rep and have seen this problem with customer and described on other sites. The problem is that the default search domain on these routers is set to mygateway.net. Changing this to a legitimate search domain is a work around for the problem, but I have seen no explaination for why the default serch domain is set to this. It has been reported for more than one ISP so it not something that just one ISP is doing.
