JungleSec ransomware – IPMI exploit removal

5 min read
JungleSec ransomware, a unique infection capable of impacting different operating systems, is on the rise, so here’s a heads-up on this new crypto threat.

The ransomware climate has been generally dull lately, with lookalike blackmail cyber-pests splashing onto the scene and vanishing shortly afterwards without leaving any noteworthy footprint. The one called JungleSec is a rare exception, though. What makes it stand out in the first place is the platform coverage. Whereas the overwhelming majority of file-encrypting viruses are Windows-only, this pest additionally supports Linux and Mac. Furthermore, it primarily zeroes in on servers rather than desktop computers, so it is primarily a headache of system admins. Yet another distinguishing feature of the JungleSec ransomware is the very peculiar distribution technique bolstering its adverse success. The architects of this campaign, which has been underway since about November, execute the perpetrating code on target machines manually. This is possible due to the exploitation of improperly secured or misconfigured IPMI (Intelligent Platform Management Interface) devices.

For the record, IPMI is a management console allowing system administrators to perform a number of maintenance and control activities with servers manually. Some of the options include turning the equipment on or off, retrieving system statistics, and accessing KVM (kernel-based virtual machines), to name a few. The interface in question can be either embedded in server motherboards or installed as a separate extra module. Given the indisputable convenience of the remote access functions, these consoles are used in numerous Internet-facing server set-ups. The flip side of this handiness is that cybercriminals have managed to find loopholes in their security. Although the entirety of entry points haven’t been unveiled at this point, one of the possible attack vectors comes down to the use of default IPMI access credentials. It’s also within the realms of possibility that the malefactors have been harnessing some zero-day vulnerabilities of said interface to infiltrate Linux, Windows, and Mac systems and run the malicious program.

Once JungleSec is in, it scans all disks for potentially valuable files. Interestingly, it may even attempt to scour virtual machine drives in the same way. Every data element spotted during this stealth traversal is subject to encryption with ccrypt, a cross-platform solution leveraging the Rijndael block cipher to securely encode files and streams. Upon completion of the crypto procedure, the ransomware stains all the locked-down files with the .jungle@anonymousspechcom or .cpt extension. It also drops a ransom notification named ENCRYPTED.md (see above). This Markdown document in plaintext format gives the victim some initial clues on what happened and how to sort things out. It says all data has been encrypted and warns the infected user about irreversible loss of the information in case they attempt to brute-force the decryption key, change filenames or alter the current path.

The attackers’ way of recovering the hostage files is all about ransom. They instruct the victim to send 0.3 Bitcoin (worth about $1,100 at the time of writing) to a BTC address indicated in the ENCRYPTED.md note. As soon as the payment is made, the user is supposed to contact the felons at junglesec@anonymousspeech.com and include the IP address of their server or computer in this message. In response, the extortionists will allegedly send the details of the recovery process within 24 hours. However, although quite a few victims have reportedly paid up, they never got any decryption steps in return. The takeaway is to refrain from submitting the ransom – while this is a standard recommendation of security experts, it is particularly relevant in this scenario. Some of the worthwhile data recovery tips backed by commonplace forensics might turn out much more effective than expecting the adversary to stay true to their promises.

JungleSec ransomware automated removal and data recovery

Owing to an up-to-date database of malware signatures and intelligent behavioral detection, the recommended software can quickly locate the infection, eradicate it and remediate all harmful changes. So go ahead and do the following:

1. Download and install the antimalware tool. Open the solution and have it check your PC for PUPs and other types of malicious software by clicking the Start Computer Scan button

2. Rest assured the scan report will list all items that may harm your operating system. Select the detected entries and click Fix Threats to get the troubleshooting completed.

Data recovery toolkit to the rescue

Some strains of ransomware are known to delete the original files after the encryption routine has been completed. As hostile as this activity appears, it can play into your hands. There are applications designed to revive the information that was obliterated because of malfunctioning hardware or due to accidental removal. The tool called Data Recovery Pro by ParetoLogic features this type of capability therefore it can be applied in ransom attack scenarios to at least get the most important files back. So download and install the program, run a scan and let it do its job.

Some ransomware strains terminate themselves after completing the encryption job on a computer, but some don’t. Furthermore, the JungleSec blackmail virus may prevent victims from using popular antimalware tools in order to stay on board for as long as possible. Under the circumstances, it may be necessary to utilize the Safe Mode with Networking or System Restore functionality.

Remove JungleSec ransomware using Safe Mode with Networking

Boot into Safe Mode with Networking. The method to do it depends on the version of the infected operating system. Follow the instructions below for your OS build.

  • Restart the machine. When the system begins loading back up, keep pressing the F8 key with short intervals. The Windows Advanced Options Menu (Advanced Boot Options) screen will appear.Boot into Safe Mode with Networking on Windows Vista and 7
  • Use arrow keys to select Safe Mode with Networking and hit Enter. Log on with the user account infected by the ransomware.
  • Click on the Search icon next to the Start menu button. Type msconfig in the search field and select the System Configuration option in the results. Go to the Boot tab in the upper part of the GUI.Boot options on Windows 8, 8.1 and 10
  • Under Boot options, select Safe boot and click the Apply button. A prompt will appear to reboot the computer so that the changes take effect. Select the Restart option and wait for the system to load into Safe Mode. Again, log on with the ransomware-stricken user account.

In Safe Mode, the ransom Trojan won’t keep security software from running or otherwise thwart troubleshooting. Open your preferred web browser, download and install an antimalware tool of choice and start a full system scan. Have all the detected ransomware components removed in a hassle-free way.

Get rid of JungleSec ransomware using System Restore

Get rid of JungleSec ransomware using System Restore

System Restore enables Windows users to roll back all changes made to the OS since the latest restore point creation time. This feature can help eliminate the most persistent ransomware. Before going this route, though, make sure System Restore had been enabled prior to the breach, otherwise the method will be inefficient.

  • Open Windows Advanced Options Menu as described in the previous section: hit F8 repeatedly when the PC is starting up. Use arrow keys to highlight the Safe Mode with Command Prompt entry. Hit Enter.Safe Mode with Command Prompt
  • In the Command Prompt window, type cd restore and hit Entercd restore command
  • Type rstrui.exe in the new command line and press EnterType rstrui.exe command
  • When the System Restore screen pops up, click Next, select a restore point that predates the contamination, and use the application’s controls to roll back the system to this earlier state.System Restore window

Be advised that even after the ransomware is removed, files will still be encrypted and inaccessible. The malicious code cleanup part, however, is important because it keeps a relapse of the infection from occurring further on and eliminates all opportunistic malware.

Ways of non-ransom recovery of files encrypted by JungleSec ransomware

Cracking the crypto used by this ransom Trojan is more of a science fiction thing rather than an attainable prospect for the masses. This is why the troubleshooting in predicaments of this sort is a matter of two approaches: one is to pay the ransom, which isn’t an option for many victims; and the other is to apply instruments that take advantage of the ransomware’s possible weaknesses. If the latter is your pick, the advice below is a must-try.

Backups can make your day

Backups can make your day

Not only are you a lucky person in case you’ve been backing up your most important files, but you’re also a wise and prudent user. This isn’t necessarily a resource-heavy activity these days – in fact, some providers of online services are allocating a sufficient size of cloud storage space for free so that every customer can easily upload their critical data without paying a penny. Having removed JungleSec, therefore, all you have to do is download your stuff from the remote server or transfer it all from an external piece of hardware if that’s the case.

Restore previous versions of encrypted files

Restore previous versions of encrypted files

A positive upshot of using this technique depends on whether or not the ransomware has erased the Volume Shadow Copies of the files on your PC. This is a Windows feature that automatically makes and keeps the backups of data elements on the hard drive as long as System Restore is enabled. The cryptoware in question is programmed to switch off the Volume Shadow Copy Service (VSS), but it has reportedly failed to in some cases.

Checking one’s options regarding this workaround is doable in two ways: through the Properties menu of each file or by means of the remarkable open-source tool called Shadow Explorer. We recommend the software-based way because it’s automated, hence faster and easier. Just install the app and use its intuitive controls to get previous versions of the encrypted objects reinstated.
Shadow Explorer

Alternatively, you can leverage the Previous Versions feature, which is native to Windows operating system. This method is more cumbersome that the use of ShadowExplorer, but it can help restore the most important individual files on condition that the ransomware failed to disable the Volume Snapshot Service on the computer. Right-click on a file of choice and select Properties. Then, go to the Previous Versions tab as illustrated below.
Previous Versions

Go ahead and pick the file’s latest backup version on the list. Use the Copy or Restore buttons to reinstate this object to a new path or to its original folder, respectively.

Ransomware Prevention Tips

To avoid JungleSec and other file-encrypting infections in the future, follow several simple recommendations:

  • Toggle your email provider’s anti-spam settings to filter out all the potentially harmful incoming messages. Raising the bar beyond the default protection is an important countermeasure for ransom Trojans

  • Define specific file extension restrictions in your email system. Make sure that attachments with the following extensions are blacklisted: .js, .vbs, .docm, .hta, .exe, .cmd, .scr, and .bat. Also, treat ZIP archives in received messages with extreme caution

  • Rename the vssadmin.exe process so that ransomware is unable to obliterate all Shadow Volume Copies of your files in one shot

  • Keep your Firewall active at all times. It can prevent crypto ransomware from communicating with its C&C server. This way, the threat won’t be able to obtain cryptographic keys and lock your files

  • Back up your files regularly, at least the most important ones. This recommendation is self-explanatory. A ransomware attack isn’t an issue as long as you keep unaffected copies of your data in a safe place

  • Use an effective antimalware suite. There are security tools that identify ransomware-specific behavior and block the infection before it can do any harm.
These techniques are certainly not a cure-all, but they will add an extra layer of ransomware protection to your security setup.

Revise your security status

Post-factum assessment of the accuracy component in malware removal scenarios is a great habit that prevents the comeback of harmful code or replication of its unattended fractions. Make sure you are good to go by running an additional safety checkup.
