An identical version for the Mac is also due shortly (a month or two) after the Windows version is released- and a demo shown. The new name, ThiefQuest, is also more fitting for our updated understanding of the malware.Create index Create IOC.

![]() ![]() It is not yet known what the purpose of these files or this additional appended data is.Even more bizarre—and still inexplicable—was the fact that the malware also modified the following files: /Users/user/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Helpers/crashpad_handler/Users/user/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Helpers/GoogleSoftwareUpdateDaemon/Users/user/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Helpers/ksadmin/Users/user/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Helpers/ksdiagnostics/Users/user/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Helpers/ksfetch/Users/user/Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle/Contents/Helpers/ksinstallThese files are all executable files that are part of GoogleSoftwareUpdate, which are most commonly found installed due to having Google Chrome installed on the machine. It contained a copy of the patch file, with a second copy of the data from that file appended to the end, followed by an additional 9 bytes: the hexidecimal string 03705701 00CEFAAD DE. Since it’s quite rare for anyone to actually log in as root, this doesn’t serve any practical purpose.Strangely, the malware also copied itself to the following files: /Users/user/Library/.ak5t3o0X2The latter was identical to the original patch file, but the former was modified in a very strange way. Both variants installed copies of the patch file at the following locations: /Library/AppQuest/com.apple.questd/Users/user/Library/AppQuest/com.apple.questd/private/var/root/Library/AppQuest/com.apple.questdIt also set up persistence via launch agent and daemon plist files: /Library/LaunchDaemons/com.apple.questd.plist/Users/user/Library/LaunchAgents/com.apple.questd.plist/private/var/root/Library/LaunchAgents/com.apple.questd.plistThe latter in each group of files, found in /private/var/root/, is likely to be due to a bug in the code that creates the files in the user folder, leading to creation of the files in the root user’s folder. InfectionOnce the infection was triggered by the installer, the malware began spreading itself quite liberally around the hard drive. I left it running on a real machine for some time with no results, then started playing with the system clock. BehaviorThe malware installed via the Mixed In Key installer was similarly reticent to start encrypting files for me. However, Chrome will see that the files have been modified, and will replace the modified files with clean copies as soon as it runs, so it’s unclear what the purpose here is. Access eq on spotify for macThis is common with malware, as having a debugger attached to the process or being run inside a virtual machine are both indications that a malware researcher is analyzing it. Screenshot of encryption message posted to RUTracker forum CapabilitiesThe malware includes some anti-analysis techniques, found in functions named is_debugging and is_virtual_mchn. Other apps would also freeze periodically, but the Finder freezes could only be managed by force quitting the Finder.Although others have reported that a file is created with instructions on paying the ransom, as well as an alert shown, and even text-to-speech used to inform the user they have been infected with ransomware, I was unable to duplicate any of these, despite waiting quite a while for the ransomware to finish. Error displayed after the keychain was encrypted by the ransomwareThere were other very obvious indications of error, such as the Dock resetting to its default appearance.The Finder also began showing signs of trouble, with spinning beachballs frequently appearing when selecting an encrypted file. This resulted in an error message when logging in post-encryption. It appeared to encrypt a number of settings files and other data files, such as the keychain files. Ioc Editor Plus The FactWhat the malware does with this capability is not known. This helps to disguise the source of the malware, as the malicious behavior may not be immediately associated with a program installed three days before.This, plus the fact that the malware includes functions with names like ei_timer_create, ei_timer_start, and ei_timer_check, probably means that the malware runs on a time delay, although it’s not yet known what that delay is.Patrick also points out that the malware appears to include a keylogger, due to presence of calls to CGEventTapCreate, which is a system routine that allows for monitoring of events like keystrokes. For example, the first ever Mac ransomware, KeRanger, included a three day delay between when it infected the system and when it began encrypting files. It’s not unusual for malware to include delays. The is_virtual_mchn function actually does not appear to check to see if the malware is running in a virtual machine, but rather tries to catch a VM in the process of adjusting time. Malwarebytes for Mac will detect this malware as OSX.ThiefQuest and remove it. Post-infectionIf you get infected with this malware, you’ll want to get rid of it as quickly as possible. For example, what kind of encryption does this malware use? Is it secure, or will it be easy to crack (as in the case of decrypting files encrypted by the FindZip ransomware)? Will it be reversible, or is the encryption key never communicated back to the criminals behind it (also like FindZip)?There’s still more to be learned, and we will update this post as more becomes known. Open questionsThere are still a number of open questions that will be answered through further analysis.
