What is ABC ransomware? And how does it execute its attack?

ABC ransomware is a recently-discovered crypto-malware that stealthily infiltrates computer systems. Since this ransomware’s activity is low, security experts are still puzzled and trying to figure out what ransomware group ABC ransomware belongs to but if you observe its appended file extension, it might actually refer to the Globe Imposter virus – developers of this malware keeps on bothering the virtual community by creating new versions of crypto-malware every now and then. On the other hand, there is also a possibility that ABC ransomware is related to ABCLocker which emerged in summer this year and it seems to be an independent crypto-malware.
Just like other ransomware infections, ABC ransomware functions as a file-encrypting threat that makes use of both RSA and AES ciphers to encrypt its targeted files. During its invasion, it looks for the following file formats on the entire computer drive:
.7z; .rar; .m4a; .wma; .avi; .wmv; .csv; .d3dbsp; .sc2save; .sie; .sum; .ibank; .t13; .t12; .qdf; .gdb; .tax; .pkpass; .bc6; .bc7; .bkp; .qic; .bkf; .sidn; .sidd; .mddata; .itl; .itdb; .icxs; .hvpl; .hplg; .hkdb; .mdbackup; .syncdb; .gho; .cas; .svg; .map; .wmo; .itm; .sb; .fos; .mcgame; .vdf; .ztmp; .sis; .sid; .ncf; .menu; .layout; .dmp; .blob; .esm; .001; .vtf; .dazip; .fpk; .mlx; .kf; .iwd; .vpk; .tor; .psk; .rim; .w3x; .fsh; .ntl; .arch00; .lvl; .snx; .cfr; .ff; .vpp_pc; .lrf; .m2; .mcmeta; .vfs0; .mpqge; .kdb; .db0; .DayZProfile; .rofl; .hkx; .bar; .upk; .das; .iwi; .litemod; .asset; .forge; .ltx; .bsa; .apk; .re4; .sav; .lbf; .slm; .bik; .epk; .rgss3a; .pak; .big; .unity3d; .wotreplay; .xxx; .desc; .py; .m3u; .flv; .js; .css; .rb; .png; .jpeg; .txt; .p7c; .p7b; .p12; .pfx; .pem; .crt; .cer; .der; .x3f; .srw; .pef; .ptx; .r3d; .rw2; .rwl; .raw; .raf; .orf; .nrw; .mrwref; .mef; .erf; .kdc; .dcr; .cr2; .crw; .bay; .sr2; .srf; .arw; .3fr; .dng; .jpeg; .jpg; .cdr; .indd; .ai; .eps; .pdf; .pdd; .psd; .dbfv; .mdf; .wb2; .rtf; .wpd; .dxg; .xf; .dwg; .pst; .accdb; .mdb; .pptm; .pptx; .ppt; .xlk; .xlsb; .xlsm; .xlsx; .xls; .wps; .docm; .docx; .doc;
As you can see, this ransomware is quite threatening as it targets various file formats. During the encryption, it applies the RSA and AES encryption algorithm to leave files unreadable and then append random 8 characters to every affected file. It leaves a text file named READ_IT.html on every folder where there is an encrypted file. It contains the ransom message that reads as follows:
“All your files have been encrypted!
You have to pay for decryption in Bitcoins. The price depends on how fast you write to us. After payment we will send you the decryption tool that will decrypt all your files.

How is ABC ransomware disseminated?
Since the activity of this ransomware is still low, it’s still hard to tell how it is disseminated exactly. However, it might be spreading in spam emails as an infected attachment like a macro-enabled document or a malicious executable file. That’s why you have to be careful in opening any kind of emails especially if you don’t know the sender or if the sender is representing a well-known group or company. It is also important that you keep both your antivirus program and system updated always so that you can prevent the infiltration of ransomware infections.

Step 7: Close the File Explorer.
Step 8: Empty the Recycle Bin.
Try to recover your encrypted files using their Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if the crypto-malware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
To restore the encrypted file, right-click on it and select Properties, a new window will pop-up, then proceed to Previous Versions. It will load the file’s previous version before it was modified. After it loads, select any of the previous versions displayed on the list like the one in the illustration below. And then click the Restore button.
