What is Dablio ransomware? And how does it execute its attack?
Dablio ransomware is a crypto-virus created using Python programming language and seems to have similarities with another crypto-virus named HolyCrypt which is also created using the same programming language. These two ransomware threats also use the same extension in marking encrypted files which is “(encrypted)”. Since developers of this crypto-malware uses Python, it allowed them to add various module to the base threat.
As soon as it enters a targeted computer, it starts to execute a sequence of attack. First, it employs a data gathering module used to collect information from the system. The information collected is classified into two, namely personal information and anonymous metric. After that, it uses the second module called stealth protection to bypass certain applications and services like antivirus programs, firewalls, and sandbox environments. Once these two modules are completed, Dablio ransomware will start to modify system setting specifically the Windows Registry where it messes with some registry keys and sub-keys, allowing it to automatically run on every system boot.
Once all the prior components have finished running, the actual ransomware module is then executed. It starts by scanning the system for files which have the following extensions:
.txt, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .jpg, .png, .csv, .sql, .mdb, .sln, .php, .asp, .aspx, .html, .xml and .psd.
After it finds its targeted files, Dablio ransomware encrypts them using a sophisticated encryption algorithm and appends the “(encrypted)” suffix to every encrypted file. Once the encryption is completed, Dablio ransomware locks the screen of the infected computer. The locked screen contains a message that states:
Good Morning. Good afternoon. Good evening.
I’m sorry to inform you that your computer was ENCRYPTED.
ALL YOUR FILES WERE COMMITED.
