That is done by selecting that option in the Flash pane of System Preferences.
DECRYPTEDFILE DMG UPDATE
Could be something new but I did think of another possibility.Įffective with the latest versions of Flash, users have the option of allowing Flash Player to update itself in the background. Restarting may well have erased it if it was, in fact, a temp file. I restarted my computer only to find that the "decryptedFile.dmg" and "Flash Player" had disappeared. If you find it come back here and I'll make arrangements to have it tested.
DECRYPTEDFILE DMG PASSWORD
I recommend you download Find Any File and search for "decryptedFile.dmg" (hold the option key down when clicking the "Find" button and supply your admin password to search everywhere on your hard drive). The reason for that is as I said before, that file is normally destroyed during the installation process or upon reboot and as you said is technically not a threat in and of itself. I know for a fact that the F-Secure tool does not check for the presence of the Flashback download/installer and I'm currently looking into the mashable script to see if it does.
That's good news, as it means the Flashback Trojan was not installed. Since posting my question, I ran the Flashback detection tool from F-Secure and a tool from. Past my bed time, so I'll have to pick this back up in the AM.
DECRYPTEDFILE DMG INSTALL
If you bought it used there is no telling what is there and you should quickly back up any user files you have, erase the drive and install the OS from the original disks. New or used? As far as I know that variant of Flashback has not been seen in the wild since late last year. Since you say you see "Flash Player" underneath, it sounds like it's mounted and the Trojan is ready for installation. dmg it should tell you next to "Write Status:" if it's not mounted. It should have been downloaded to a temp area which is normally emptied of everything on reboot, but it sounds to me like something may have gone wrong with that.ĭisk Utility has a habit of remembering files that it has mounted in the past and displaying them in an unmounted state. If it's actually still on your hard drive then it is capable of installing/reinstalling one of the older variants of Flashback. Underneath the name of my hard drive and SuperDrive is "decryptedFile.dmg" and underneath that on a sub-level is "Flash Player." I researched online and found that "decryptedFile.dmg" is a sign of the Flashback trojan, but I've also read that it is a harmless 'leftover' from installing Flash Player. I opened Disk Utility and noticed that a seemingly strange file was showing up. It makes a big difference on how we approach this.įirst off, I am a new Mac user, so bear with me.
Since you are posting to the iMac (Intel) forum, I know that much, but what OS X are you running. You haven't filled out your profile yet, so I don't know a lot about your setup. its_Targeted_Attacks_and_Possible_APT_linkĬrisis OS X Trojan is an effective spy tool…Ĭheck now whether your Mac is infected by Backdoor.Flashback.39! The most current flashback removal instructions are F-Secure's Trojan-Downloader:OSX/Flashback.K. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot. If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so.
