What is Thanatos ransomware? And how does it carry out its attack?

Thanatos ransomware is a malicious program designed to lock files using an encryption algorithm. This generic file-encoding Trojan first appeared on February 17, 2018. According to researchers, it reaches a system through phishing messages that may look like it was sent by trusted companies like Amazon, eBay, Facebook and so on. Based on the initial analysis done by security experts, it seems that Thanatos ransomware uses a modular framework. Meaning to say, any future updates that will be applied on this crypto-malware can reshape it and model the strains in an entirely different manner.
Thanatos ransomware is programmed to target several data types, which according to researchers are as follows:
.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp
Thanatos ransomware makes use of a resource fork file containing all the malware commands. This kind of infection is a specific one that in some cases can be used to conceal information and hacker-set parameters. Aside from that, Thanatos ransomware also contains information about extracting module that can query the operating system kernel. The malware engine can collect the list of all the running processes and terminate all of them so that it can carry out its attack without any interference.
The information harvesting module found in Thanatos ransomware has been found to collect information about the infected PC as well as information about the user. Usually, the kind of information gathered is classified into two – one is anonymous data while the second one is personally identifiable information.
In addition, Thanatos ransomware also modifies the Registry so it can run on every startup. However, what has security experts worried is that this crypto-malware is found to be bundled with the Thanatos virus which can modify the proxy settings of the infected computer. As a result, the compromised computer routes all the internet traffic through the hacker-controlled server which allows cyber crooks to utilize man-in-the-middle attacks and spy on its victims. Not only that, as this threat can also download files prior to the encryption process. Once Thanatos ransomware is done carrying out its attack, it drops a file named README.txt which contains the following message:
“Your computer is encrypted. All data will be lost if you do not pay 0.01 BTC to the specified BTC wallet
after payment, you will receive the decryption code from this mail
[email protected]
How does Thanatos ransomware spread its malicious payload?
Thanatos ransomware may spread as an infected attachment in spam emails that care sent out by crooks, making the email look like it was sent out by a famous company like Amazon, eBay, etc. which is why you have to be careful when you encounter these kinds of emails because chances are, it might contain a malicious payload of harmful cyber threats like Thanatos ransomware. It would also be best if you always keep your antivirus program and system updated to guard your system against malware and other viruses.
