We’ve just added detection and description for a new Symbian Series 60 trojan that we named Fontal.A.
This is a SIS file trojan that installs a corrupted file which causes phone to fail at reboot. If user tries to reboot the infected phone, it will be permanently stuck on the reboot, and cannot be used before disinfecting.
Currently the only known method of repairing the phone is to use the reformat key combination, which causes the phone to lose all data. And because of that, we are not writing the code here on the weblog.
The Fontal.A is a trojan, and as such it does not spread by itself, not over bluetooth or any other channel. Most likely way to user to get infected would be to get the file from IRC or Peer to Peer fileshare and install it to the phone. So to avoid Fontal and other trojans, download files only from legal sources.
It’ll be interesting to see how this one pans out…
CherryOS developer MXS caused quite a stir late last year with the announcement of CherryOS, an application that would emulate the Macintosh operating system on a Windows PC. Soon after news of CherryOS hit, fans of the open source PearPC cried foul saying that CherryOS had copy code from the open source project and were selling it as commercial software.
