Ranstop stops Sodinokibi ransomware
Ransomware test subject – Sodinokibi
A very serious vulnerability (CVE-2019-2725), with a CVSS score of 9.8 (out of 10) affected a few versions of Oracle’s WebLogic servers. The vulnerability allowed the attackers to remotely download and execute malware – without authentication – like this ransomware, called Sodinokibi, affecting businesses and disrupting operations.
What this really means is that the cybercriminals don’t even have to bother to send you emails, fool you to click on links or to open attached documents. All they have to do is to find your vulnerable server and simply execute the malware on it. And that’s that. Your files are gone.
Fortunately, in this case, only a few versions of WebLogic were affected, and the vulnerability was patched a few days ago, so you better update your products as soon as possible.
This isn’t the only case of remote code execution vulnerability. There are many in even more products that we can count. They happen to be because of the complexity of IT ecosystems, even though software companies are doing absolutely everything they humanly can to avoid them.
Sodinokibi ransomware – test findings
The unfortunate part is that the cybercriminals exploiting this vulnerability happened to push ransomware, making the aftermath even more catastrophic.
Once executed on the attacked servers, it immediately starts encrypting important files. On our test machine, Sodinokibi encrypted most, but not all of our test files, and appended a new file extension with each run. This means that every time the ransomware executes, your files will be renamed differently. It will also delete shadow volume copies of files (these are backups automatically made by the operating system, if the feature is activated). The malware also makes it difficult to access Windows Startup Repair.
Once done, it will change the desktop wallpaper and drop a ransom note in each attacked folder. The ransom note contains a link and a code, which the user needs to paste into a tor webpage. Afterward, the price of recovery is returned. Because the cybercriminals target businesses, the price of recovery is steep, between $2500-$5000 in Bitcoins.
Sodinokibi ransomware vs Ranstop – test results
TEMASOFT Ranstop detects this version of Sodinokibi ransomware soon after it starts encrypting files. Upon detection, alerts are fired off, and the malware process is stopped and quarantined. The affected files are automatically recovered so that the user doesn’t lose any important document.
