In the case of this Crossrider variant, the configuration profile that is installed forces both Safari and Chrome to always open to a page on chumsearchcom. These profiles can configure a Mac to do many different things, some of which are not otherwise possible. Configuration profiles provide a means for IT admins in businesses to control the behavior of their Macs. It turns out that this is caused by a configuration profile installed on the system by the adware. Safari’s homepage setting is still locked to a Crossrider-related domain, and cannot be changed. After removing Advanced Mac Cleaner, and removing all the various components of Crossrider that have been littered around the system, there’s still a problem.
This is all very blasé, as far as malware goes.īut something interesting has happened behind the scenes.
(No such problems actually exist, of course.) Safari also pops open and then closes again suspiciously. In the course of installation, it dumps a copy of Advanced Mac Cleaner, which commences to announce that it has found problems with your system using Siri’s voice.

Opening the installer results in a familiar install process, with nothing unique about it. It’s yet another fake Adobe Flash Player installer, looking like the thousands of others we’ve seen over the years. This new Crossrider variant doesn’t look like much on the surface. So malware creators are often stuck using the same old methods of persistence that are easy to spot. After all, what good is it to infect a machine if the malware stops running as soon as the computer restarts? There are some cases where that can still be useful (ransomware, for example), but in most cases, that’s not desired behavior. However, the use of a configuration profile introduces a unique new method for maintaining persistence. For the most part, this variant is still quite ordinary, doing some of the same old things that we’ve been seeing for years in Mac adware. A new variant of the Crossrider adware has been spotted that is infecting Macs in a unique way.
