Jaff encryption stems from Locky ransomware, comes from deadly Necrus botnet
The first report on Jaff encryption-for-ransom dates back to May 11, 2017. A powerful botnet called Necrus spreads its copies at the astonishing rate. The infection vector leverage account hacked and included into the network controlled by hackers. Despite the tactic is primitive, targeting so many users eventually yields a number of victims.
The ransomware is not a brand dew strain. It is rather a rough remake of the notorious Locky encryption trojan. Anyway, Jaff virus makes use of a good deal of its components and schemes. In particular, the two viruses share a single HTML for the ransom transfer purposes.

The latest attempts to totally eliminate damages caused by the malware installation have not yielded a satisfactory outcome. Unfortunately, the encryption algorithms applied are strong enough. The search for any flaws and vulnerabilities is ongoing.
Most of the users get the ransom plague onboard as they open an email titled according to the following pattern Scan_[set of random digits]. The spam includes attachment, a DOCM file. Even at this stage you still can avoid the encryption. Just do not open the content. Even if you do, the malware cannot install unless you click Enable Content.
If you have downloaded the attachment, remove it without opening. That is the last plausible chance to get rid of Jaff ransomware before it malicious encryption completes.
The installed instance of the ransomware is going to connect to the remote Command-and-Control Centre. However, unlike its counterparts, the trojan is not going to wait for approval. It proceeds with the encryption even if the compromised device suddenly goes offline. It only communicates to the remote server unique details of the hacked machine so that the hackers are aware and record the successful installation. The only response received is ‘Created’.

AES cipher applies as the ransomware hacks the files of over 400 extensions on a host machine. Frankly, it hardly omits a single meaningful bit of data. The only exemption extends to critical system files. That ensures the victim is going to read the ransom note and visit the payment website.
The infection creates a dedicated file for the desktop wallpaper. It is the same as ReadMe.*, where ‘*’ is the file format. If you read it, the obvious message will notify you that your files are encrypted. The only offered salvation is the application of private key to be purchased for nearly 4,000 USD in bitcoins.
Most of the victims reasonably discard such a generous offer. If you are among them, proceed with relevant ransom-free anti-encryption workarounds below.
Automated cleanup to remove Jaff encryptor
Infection vector for ransomware typically features a trojan. The one in question definitely subscribes to that routine. The trojan drops its body into target computer and proceeds with disabling the detecting functionality of any security solution installed. The antivirus is thus unable to spot introduction of virus from the remote server.
The ransomware invasion is indicative of its dropper residing in the computer memory. It also hints at other invasions. The PC can hardly be considered properly protected due to the impacts of the above trojan.
Ultimate option implies a total formatting for any drives of your PC. That is not an option for many users, for it destroys all the data hosted by the machine. The best solution to pick would be in-depth system examination with a reliable security suite.
The trojan that has installed Jaff ransomware, unless removed, is to trigger its installation campaign as soon as a new strain of ransomware is available. Thereby, it is critical to kill it as soon as possible.
The technique successfully overcomes malicious software, including any ransoming threats. It deploys a reputable security suite that offers not a single chance for malicious components to avoid detection and extermination. The software is incredibly user-friendly and operates on a single-click basic.
It is good to note the removal of Jaff ransomware does not recover the data affected. However, the virus is subject to compulsory extermination or else is going to introduce related infections into the machine.
1. Click the button to download the stub installer and go through several setup dialogs. Once the tool is up and running, click Start Computer Scan
2. Wait until the cleaner checks the PC for Jaff malicious code. As soon as the scan is completed, the report will list all malware objects spotted in the system. Make sure the entries for detected infections are checked, and select the Fix Threats feature. This will result in malware removal and system remediation, so you should now be good to go.
Restore the encrypted files
Jaff ransomware encryption is a sophisticated data modification. There is no simple and single solution to cover all the cases. Transferring the ransom as demanded by the crooks is not the way either.Kindly apply the methods outlined below as they have been carefully developed to provide a recovery help for the most severe cases of encrypting assaults.
Data recovery with automatic software
Good news is that the virus actually deals with copies of the files. The originals have been deleted. The removed data still can be restored by virtue of such tools as Data Recovery Pro.
Shadow Volume Copies
As Windows creates backups at given periods of time, a victim is advised to address relevant restore points. Unfortunately, the method cannot apply unless the System Restore had been enabled prior to the invasion. Please also note the recovery returns files as saved before the time associated with the restore point addressed.
- Previous Versions dialog to target individual files
One can open Properties for any file. The menu has a tab called Previous Versions. It indicates versions of a file that have been backed up.
To make use of the feature, right-click an affected file and choose Properties in the drop-down list. Proceed with clicking the above-mentioned tab. You can opt between the Copy or Restore procedures, the former enabling to copy the item into the location specified by the user.
Backups and removing remaining traces of Jaff ransomware
Prevention is the best cure. If you stick to making regular reserve copies of your data and store those outside your operating system, the impacts by the ransomware are very limited. However, prior to copying the data from backups into the system hit by Jaff encryptor, make sure the removal of this virus has completed.
Your manual removal attempts may kill the ransomware in general. In most of the cases, some remnants manage to survive and are still capable of causing a significant damage. Please apply a reliable anti-malware scanner to detect and remove, if applicable, any remaining infections.
