Researchers with the Russian multi-national security company Kaspersky have discovered a new OS X malware, dubbed Ventir. Reportedly it contains a keylogger, a Trojan, and a backdoor that allows the hackers to keep on accessing compromised machines. Reportedly, Ventir is lined up next to the most sophisticated computer malware, which can only suggest that hackers are now targeting Macs more increasingly. OS X used to be untouched by crooks in the past, but as the market value of the Apple products increased, the attention of the cybercriminals got drawn them.
What Does Ventir Do?
As the Ventir infiltrates the targeted machine, the dropper component of the Trojan tries to establish if it has root access to the compromised PC. This is of highest importance to the process of installation of the malware. In case it manages to gain root access, Ventir can do way more harm to the affected machine. This is why computer users, both Windows and Mac, are recommended to avoid using administrator-privileged accounts when they browse the Web.
The keylogging component of the new malware piece is able to log every key that is being pressed on the victim’s PC and send the logs to the creators of the malware. This way the cyber-crooks can get their hands on email addresses, passwords, search queries, browsing history, contacts, etc.
Ventir Involved in Data Theft Campaigns?
Researchers believe that Ventir may have been used in data theft campaigns recently. They associate the malware from the same family as Ventir with the current leaks of credentials from Gmail, Mail.ru and Yandex.
The keylogger’s kernel extension of the malware is open-source code that is available on GitHub for free, which according to the security experts makes it easier for the hackers to create new malware versions. Users should only expect the amount of Trojan-Spy programs to increase in the feature.
Kaspersky Lists the Following Features of Ventir
As soon as it is launched, the dropper checks whether it has root access by calling the geteuid () function. The result of the check determines where the Trojan’s files will be installed:
- If it has root access, the files will be installed in /Library/.local and /Library/LaunchDaemons;
- If it does not have root access, the files will be installed in ~/Library/.local and ~/Library/LaunchAgents (“~” stands for the path to the current user’s home directory).
- All files of the Trojan to be downloaded to the victim machine are initially located in the “__data” section of the dropper file.
EventMonitor spying component is used only if elevated privileges are not obtained. “Immediately before processing a keystroke, the malware determines the name of the process whose window is currently active,” says Kuzin in a blog post.
As a result, the following files will be installed on the infected system:
- Library/.local/updated – re-launches files update and EventMonitor in the event of unexpected termination.
- Library/.local/reweb – used to re-launch the file updated.
- Library/.local/update – the backdoor module.
- Library/.local/libweb.db – the malicious program’s database file. Initially contains the Trojan’s global settings, such as the C&C address.
- Library/LaunchAgents (or LaunchDaemons)/com.updated.launchagent.plist – the properties file used to set the file Library/.local/updated to autorun using the launchd daemon.
Depending on whether root access is available:
А) if it is – /Library/.local/kext.tar. The following files are extracted from the archive:
- updated.kext – the driver that intercepts user keystrokes
- Keymap.plist – the map which matches the codes of the keys pressed by the user to the characters associated with these codes;
- EventMonitor – the agent which logs keystrokes as well as certain system events to the following file: Library/.local/.logfile.
B) if it isn’t – ~/Library/.local/EventMonitor. This is the agent that logs the current active window name and the keystrokes to the following file: Library/.local/.logfile.
What experts suggest in order to protect your system from this and some other malicious software is to not log with administrator rights when just browsing the internet or using programs that don’t require it.
