What is Assembly ransomware? And how does it carry out its attack?
Assembly ransomware is a crypto-virus which belongs to the category of mid-tier ransomware. This newly discovered crypto-malware is created based on the open-source platform, HiddenTear. It uses the same encryption algorithm that Sorry HT ransomware and Deos ransomware uses which is the AES cipher.
Assembly ransomware carries out its attack using a malicious executable file named “assembly.exe” on infected systems. This malicious executable file is used to modify Windows system files as well as the Windows Registry so it can avoid detection from any security programs installed in the computer and so it can also run on every system boot. It then scans the system looking for certain files to encrypt that has the following extensions:
.asp, .aspx, .cpp, .csx, .csv, .doc, .docx, .html, .jpg, .mdb, .odt, .pdf, .php, .png, .ppt, .pptx, .psd , .raw, .rtf, .sln, .sql, .txt, .vb, .xls, .xlsx, .xml
Assembly ransomware creates its ransom note named “READ_ME.txt” which might be placed in the Documents and Desktop folders. This ransom note contains the following context:
“All files have been encrypted
Send 1000 $ in BTC to
and send your computername to
in order to decrypt the files.”
According to security experts, there were some victims who went ahead and paid the ransom demanded by the crooks which amount less than $1000. This is such a huge amount so don’t make the same mistakes that other victims did for you will only waste your money. Instead, you must make the elimination of Assembly ransomware your topmost priority. And once you have that covered, you can find alternative ways to recover your encrypted files and use backup copies of the encrypted files for the meantime.
How is the malicious payload of Assembly ransomware disseminated?
Assembly ransomware is believed to arrive in the system using spam emails. Cybercrooks often use malicious files like documents with macro scripts. These macro scripts are used to download and install Assembly ransomware into the system. In addition, the malicious payload could also be a file pretending to be a fake software or software update so you also have to be cautious on websites that offer these kinds of updates or software.
