Unlike other types of malware, you can't just clean it ransomware and continue your day. A run-of-the-mill virus will destroy all your data and backups. For this ransomware is a risk for which you will need to prepare in advance.
Are you in danger?
Definitely an attack ransomware is dangerous, but not all risks are the same. For example, an asteroid strike is a known hazard. Should we spend trillions of dollars defending ourselves against this threat that occurs once every 100 million years? Not necessarily, because the risk of an immediate hit is quite low. So, for the ransomware, we must consider the level of risk for a permanent data loss.
Part of the risk assessment is to see how well prepared we are for such an attack. There are many things we can do to keep our data safe. Because the ransomware can and will encrypt all the files it finds on your computer or on a connected network, we need to choose a backup solution that makes our files inaccessible.
One such solution is the "air gapping" of your backup disk, which means that it is not constantly connected to your computer or network. Another option is a backup tool so you can restore your files. If you have a secure, isolated backup, an attack ransomware It may be unpleasant, but you can get over it without too much difficulty.
Combined with other precautions, such as not clicking on links that you do not trust, may be sufficient for the security of your computer.
There are also some easy ways in which you can add protection for ransomware on your computer without installing any other security software. The existing Windows antivirus package already offers some protection. Windows Defender, the default antivirus for Windows 10, has some built-in protection ransomware, but is disabled by default.
If you enable protection for ransomware Windows Defender "Folder Access Control" software will protect your shared folders, such as Documents and Images, from unauthorized changes. If an application ransomware can not access the Documents folder, can not encrypt your files. There are also free apps like RansomBuster of Trend Micro, which works the same way.
Unfortunately, this approach is not infallible and can become very annoying in practice. Many programs need to access your document folders regularly, so you may need to grant them multiple permissions.
The Ransomware remains a serious threat
Some experts believe that ransomware does not hit home computers. Criminals tend to focus their efforts on victims with deep pockets. Check Point's recently published Cyber Security 2020 report agrees with this assessment:
"In 2019, we saw an escalation of sophisticated and targeted attacks ransomware. Certain sectors have suffered serious casualties, such as state and local agencies, as well as health services. ”
The 2019 titles were full of such attacks on more than 70 state and local authorities. If you are not a bank or government of a city, you may have to worry less about ransomware in 2020 than several years ago, as the current attacks ransomware are more targeted.
This is good news for your home computer, however, do not rejoice…
It is easy to conclude that ransomware It is no longer a problem for consumers, but we know that cybercrime, and tactics, are cyclical. They keep coming back.
Jonny Pelter, CEO of SimpleCyberLife.com reports:
"The volume of attacks ransomware has begun to decline, but the level of attacks is still high.
Of course, this will make its development and distribution ransomware by cybercriminals much more lucrative, Unfortunately, I'm afraid we are entering a period of complacency. As the attacks ransomware abandoned by the mainstream media, and people misinterpret it as a reduction in the number of attacks by ransomware, which is far from reality, unfortunately. ”
Prevention software Ransomware
All this means that you can be relatively safe in the short term, but it is still a good idea to protect yourself with some prevention software. ransomware. Home computers have been relatively vulnerable for several years, but today there are many packages anti-ransomware from which you can choose - free and paid.
Almost all standard antivirus packages now offer some level of protection against them ransomware. However, many of them (and most free packages) are based on the same technology used by traditional antivirus programs. Detect signatures of known software to identify malware. The disadvantage of this approach, of course, is that it leaves you vulnerable to 0day.
In contrast, most individual packages ransomware, As the Acronis Ransomware Protection , the Check Point ZoneAlarm Anti-Ransomware and Malwarebytes Anti-Ransomware Beta, detect malware by its behavior.
These programs monitor the activity of quarantined applications and processes that have suspicious activity, such as creating an encryption key or initiating file encryption.
This makes these applications much more effective at shutting down ransomware from the beginning, whether it is some well-known software or a brand new malware.
