AutoLocky Ransomware – Distribution

To spread to various systems, this ransomware may use several different distribution methods. One of them is via malicious links posted on social media, comments or as replies on forums. The other distribution method that you are more likely to encounter is via spam e-mails. The spam e-mails may contain different malicious files in an archive. Some of those files are usually Microsoft Word, Excel or .PDF documents with infected macros. This means that when the document is opened, and editing is enabled by the user, the malware may use a malicious macro script that will infect the user with malware.

AutoLocky Ransomware In Detail

Once activated on the victim PC, AutoLocky creates several files in key Windows folders:

→ Startup executable located in the “%UserProfile%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\Start.lnk.” file.
“%UserProfile%\Desktop\info.html – Ransom note

The ransomware then begins to look for the following files to encrypt:

→ .pptx,.sql,pat,fxg,fhd,fh,dxb,drw,design,ddrw,ddoc,dcs,wb2,psd,p7c,p7b,p12,pfx,pem,crt,cer,der,pl,py,lua,css,js,asp,php,incpas,asm,hpp,h,cpp,c,csl,csh,cpi,cgm,cdx,cdrw,cdr6,cdr5,cdr4,cdr3,cdr,awg,ait,ai,agd1,ycbcra,x3f,stx,st8,st7,st6,st5,st4,srw,srf,sr2,sd1,sd0,rwz,rwl,rw2,raw,raf,ra2,ptx,pef,pcd,orf,nwb,nrw,nop,nef,ndd,mrw,mos,mfw,mef,mdc,kdc,kc2,iiq,gry,grey,gray,fpx,fff,exf,erf,dng,dcr,dc2,crw,craw,cr2,cmt,cib,ce2,ce1,arw,3pr,3fr,mdb,sqlitedb,sqlite3,sqlite,sql,sdf,sav,sas7bdat,s3db,rdb,psafe3,nyf,nx2,nx1,nsh,nsg,nsf,nsd,ns4,ns3,ns2,myd,kpdx,kdbx,idx,ibz,ibd,fdb,erbsql,db3,dbf,db-journal,db,cls,bdb,al,adb,backupdb,bik,backup Source: BleepingComputer

So far it is believed that the ransomware uses strong RSA-2048 and AES-128 encryption algorithms which are practically near impossible to decipher directly. After file encryption, the ransomware displays the following ransom message:

→ “Locky Ransomware
All of you files are encrypted with RSA-2048 and AES-128 ciphers.
More information about the RSA and AES can be found here:
{links to Wikipedia}
Decrypting of your files is only possible with the following steps.
How to buy decryption?
1.You can make a payment with BitCoins; there are many methods to get them.
2.You should register BitCoin wallet (simplest online wallet OR some other methods of creating wallet)
3.Purchasing Bitcoins – Although it’s not yet easy to buy bitcoins, it’s getting simpler every day.”

The ransomware has been reported to demand around 0.75 BTC as ransom money from the victims. However malware research experts report that it does not use Tor networking like the original Locky Ransomware, and it uses different programming language than Locky’s C++.
