Have your backups of data been destroyed following a ransomware attack? This notorious cyberattack can infect all your files, and thereby paralyze your operations. It is always accompanied by ransom demands that lead to harassment. Rest assured, you are not obliged to give in to cybercriminals’ pressure to recover your files. Chronodisk, your expert in data recovery, explains how to easily recover your backups after a ransomware attack.
How does a ransomware attack manifest?
Ransomware is a highly ingenious attack developed by hackers to make money from businesses. It infects the files on storage servers, then holds them hostage by locking access to them. Consulting the files in question then becomes impossible, and cybercriminals impose a ransom that is very often high. Many companies that fall victim to these attacks don’t know how to react, and give in to the hackers’ pressure given the importance of their data.
Also known as ransomware, this attack encrypts all hijacked files, and sometimes destroys the backups set up for saving and archiving data. It specifically exploits weaknesses in the operating system to spread throughout all storage systems. After completely neutralizing your backups, this malicious software restarts your machines, then displays a new window with a message explaining how to pay the ransom. The payment deadline is short, and the amount is often between $500 and $1000. If no backup has been made on an external medium such as an external hard drive or virtual machines in the cloud, you are forced to pay. If you refuse, you risk having your data handed over to a competitor or published on the Internet.
How can you recover your data in the event of a ransomware attack?
Backups are a backup system that copies and archives files so they can be restored in the event of theft or loss. For a company, they represent the best internal solution for recovering destroyed data.
However, backups are recovery software that hackers already manage to infect. This is why a carefully designed ransomware attack destroys them and blocks access to them. Nevertheless, no cyberattack is perfect, and ransomware is no exception. Indeed, cybercriminals carry out their intrusion very quickly, and don’t have time to encrypt every file. Some fragments of data remain in their original state, and make it possible to know how to rewrite the entire content. This is why it is essential to have a large stock of backups, since we will use a copy to recover all your files. Thanks to our expertise, you will no longer need to respond to ransom demands. Our storage services include Veeam backups to quickly recover your files and prevent intrusions.
Our success stories in this field are tied to the measures we use to know how to recover all lost files:
- Isolating network workstations and servers suspected of containing viruses, to prevent the ransomware from spreading throughout the entire system.
- Determining the scope of the infection by identifying the business software that infiltrated your system. Indeed, each ransomware attack destroys a particular category of files, and spreads in its own specific way.
- Carrying out an inventory of the storage hardware by determining the number of destroyed servers and any available replicas.
- Assessing the destroyed files to identify their nature (databases, office documents, etc.), as well as the departments most affected by this loss.
- Limiting the risk of mishandling, which often reduces the chances of recovering the files. These bad practices concern operations carried out on the servers.
- Shutting down the storage servers to prevent the virus from randomly deleting certain files.
- Optimizing backup systems to facilitate file recovery.
- Checking and preserving backups launched automatically before the cybercriminals’ attack. The goal is to prevent the destroyed files from damaging those still in good condition.
- Support from a team of experts in cybercrime, as well as in storage, reintegration, and securing of data.
- Calling on the services of experts in data recovery
How can you effectively secure your data?
Ransomware attacks are becoming increasingly sophisticated, and are giving businesses a hard time. Yet a few basic measures can help counter this threat. The first is to keep your antivirus software up to date, along with your operating system. Next, you should set up several backups to optimize file backup and recovery. In addition, it is necessary to have external storage media available. A practical solution is to use the cloud. Also, when you share files over the internet, make sure the transmission line is properly secured.
