This entry is about ransomware called Mole03 that gets into PC around the world, and corrupts their files. In this entry we've compiled complete info about Mole03's essence, and the uninstalling of Mole03 from the laptop. Furthermore, we'll explain how to get back the cyphered files and is it possible.

Mole03 ransomware already infected many machines around the world with help of basic way: fraud messages with viral attachments. Sometimes web-criminals use exploits to penetrate the system, but they are quickly fixed. After penetration, Mole03 scans the computer memory to find the folders to be encrypted and their general value. Currently, any modern ransomware can encrypt text, video, image and audio info in all known extensions. Virus corrupts all folders, but the ones that look like business documents go first. All programs in the system will be unaffected since criminals are interested only in information. The process is executed via famous encryption algorithms, and its intricacy is so above the average level that it cannot be bruteforced. Such complexity creates base for impressive effectuality of ransomware in recent years: an ordinary PC operator, even if he has a fairly good experience in suchlike things, will never recover the files, and will be forced to pay the price. The single manner to decrypt files is to find the fraudster's site and obtain the master key. Also there's a way to get encryption keys through flaws in viruse's program code.

Mole03 ransomware virus

The knowledge of computers is very significant in our world, since it helps customer to protect the system from hazardous software. For encrypting software it's very relevant, as, unlike common unwanted software, after eliminating ransomware from the computer, the consequences of its actions do not vanish anywhere. It's very easy to minimize the chances to get ransomware by following these rules:

    • Pay attention to the pop-up windows. If the machine is polluted by ransomware, it will seek to eliminate the shadow copies of your files, to make the decryption less possible. The deletion of copies requires admin rights and user's verification. Thus, if you do not accept changes from a suspicious program at the proper moment, you will save the opportunity to decrypt all encrypted information for free.
    • Attentively examine your mailbox, particularly those messages that have attached files. If this letter was sent from an unknown address and it notifies about obtaining some prize, a lost parcel or anything like that, this could be a scam letter. The second most common type of scam messages is a "business letters". complaints, Invoices for products and services, lawsuits, summaries and similar sensitive files don't come accidentally, and the receiver should know the sender. In all other cases it is a scam.
    • Don't neglect the signs that your computer shows. Information encrypting is a intricate process that uses a lot of hardware resources. If you see an abnormal decrease in workstation power or detect a weird string in the Process Manager, you should unplug the machine, start it in safe mode, and scan for malware. These measures, if the PC is really infected, will save a lot of your files.
