How to Protect From Ransomware Attacks?
Get A Good Protect Ransomware Attacks Steps
Update your software
Security experts believe the malware that spurred this global attack, called WannaCry, may have initially infected machines by getting people to download it through email. After that, the malicious code was able to easily travel to a broader network of computers that were linked together through the Windows file-sharing system. (Users of Macs or other non-Windows computers were not affected.)
The most disheartening revelation from the cyber attack was that there was a fix available for the ransomware before the attack. Microsoft, which makes Windows, released a patch for the WannaCry vulnerability eight weeks ago, the chief technology officer of Vera code, an application security company.
In other words, if people had simply stayed on top of security updates, their machines would not have been infected. “People kind of got complacent and not vigilant about updating their machines.
Consumers can remedy this by configuring their Windows machines to automatically install the latest software updates.
Even though WannaCry specifically targeted Windows machines, that does not mean Mac or Linux users are off the hook in the future. Other breeds of malware may infect various operating systems, so no matter which device you are using, you should regularly update your software to install the latest security enhancements.
Install antivirus software
In addition to keeping Windows up-to-date with the latest security enhancements, antivirus software can prevent malware from infecting your computer. its 30 percent of popular antivirus systems were capable of detecting and neutralizing the ransomware.
Of course, with antivirus software, the same principle applies: Make sure to keep the antivirus app up-to-date, too, so it blocks the latest emerging malware. Also, download antivirus apps only from reputable vendors like Kaspersky Lab, Bitdefender or Malwarebytes and othes.
Beware of suspicious emails and pop-ups
Security experts believe WannaCry may have initially infected machines via email attachments. The lesson: Avoid clicking links inside dubious emails.
How do you spot a fishy email? Look carefully at the email address of the sender to see if it is coming from a legitimate address. Also, look for obvious typos and grammatical errors in the body. Hover over hyperlinks (without clicking on them) inside emails to see whether they direct you to suspicious web pages. If any email appears to have come from your bank, credit card company or internet service provider, keep in mind that they will never ask for sensitive information like your password or social security number.
In addition, ransomware developers often use pop-up windows that advertise software products that remove malware. Do not click on anything through these pop-ups, then safely close the windows.
Create backups of your data
In the event that a hacker successfully hijacks your computer, you could rescue yourself with a backup of your data stored somewhere, like on a physical hard drive. That way, if a hacker locked down your computer, you could simply erase all the data from the machine and restore it from the backup.
In general, you should be creating a copy of your data in the first place, in case your computer fails or is lost. To be extra safe from hackers, after backing up your data onto an external drive, unplug the drive from the computer and put it away.
security plan Create For business
For larger and small businesses with hundreds or thousands of employees, applying security updates organization wide can be difficult. If one employee’s machine lacks the latest security software, it can be infect other machines across the company network.
it businesses could learn from how WannaCry spread through the Windows file-sharing system by developing a strict schedule for when computers company wide should automatically install the latest software updates. Businesses should determine the best time to apply these security updates to office computers without interrupting productivity, he added.
Information technology professionals should also regularly educate and test employees on spotting suspicious emails, junk mails, vice president of Crypsis, a cybersecurity firm.
What to do if already infected
If you are already a victim of ransomware, the first thing to do is disconnect your computer from the internet so it does not infect other machines. Then report the crime to law enforcement and seek help from a technology professional who specializes in data recovery to see what your options might be. If there are none, don’t lose hope: There may be new security tools to unlock your files in the future.
In some extreme cases, it might make sense to pay a ransom if you have no backups and the encrypted files are valuable. But added that with WannaCry, people definitely should not pay the ransom.
