What is Qmam4 Ransomware
Qmam4 is a high-risk infection categorized as a cryptovirus. The reason why it is named that way lies in its after-attack behavior – the virus demands victims to pay a sum of money in cryptocurrency upon blocking access to data. Such infections are also known as ransomware. They encrypt personal data and blackmail victims into paying the ransom. During encryption, Qmam4 attaches a string of random characters and the new .qmam4 extension to each affected file. For instance, 1.pdf will change to 1.pdf.{random sequence}.qmam4 becoming no longer accessible. Following this, Qmam4 creates a text file called D4RT_HOW_TO_DECRYPT.txt that illustrates how victims can unlock their data.

Follow the guidelines below to avoid losing your data:
- Do not modify, rename or delete *.key.qmam4 files. Your data will be
undecryptable.
- Do not modify or rename encrypted files. You will lose them.
- Do not report to the Police, FBI, etc. They don't care about your business.
They simply won't allow you to pay. As a result you will lose everything.
- Do not hire a recovery company. They can't decrypt without the key.
They also don't care about your business. They believe that they are
good negotiators, but it is not. They usually fail. So speak for yourself.
- Do not reject to purchase. Exfiltrated files will be publicly disclosed.
It is said victims can decrypt and prevent important data from being sold on dark web resources. To do this, victims are instructed to contact cyber criminals using the Tor link. After getting in touch with the developers, they will supposedly tell you to send money in cryptocurrency and retrieve a special decryption tool afterward. Should victims refuse to follow instructions, the collected data will be leaked to the hands of third-party figures. Unfortunately, collaboration with cybercriminals might be the only way to decrypt your data and avoid publicly exfiltrated data. It is less likely that some third-party tool will be able to decrypt your data for free without the help of attackers. You can definitely restore your data using backup copies, however, this will not stop the attackers from manipulating your data to their personal benefit. Note that it is important to delete the infection before recovering data without cybercriminals. Otherwise, it may continue encryption and impact other devices that will be connected to the system. To do this and learn more about recovery methods, follow the guidelines below.
How Qmam4 Ransomware infected your computer
Ransomware infections are mainly distributed via email phishing messages, trojans, fake software updates/installers, exploits, web-injects, backdoors, keyloggers, and various other vectors. Email phishing is simply when cybercriminals set up bots to send spam letters containing malicious attachments. These letters are likely to be disguised as something legitimate and trick users into opening files or links. The attached files are usually macro-based Word, Excel, PDF, EXE, or Javascript files capable of executing the installation of malware. Beware of such messages and do not download software from unofficial resources. You may also be bombarded by dubious ads on third-party pages offering to download an antivirus because your system is allegedly infected. However, instead of delivering an actual antimalware utility, such websites promote trojans that are meant to install different malware. We encourage you to follow our tutorial below and learn how one can protect himself against such threats in the future.

How to protect computer from viruses, like Qmam4 Ransomware, in future
1. Get special anti-ransomware software
Use ZoneAlarm Anti-Ransomware
Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.
2. Back up your files
As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. Qmam4 Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
