Ransomware on the Rise: What You Can Do To Protect Your Organisation From The Attack
Ransomware is malicious software used by the cyber criminals to hold your computer files or data and demand for a payment from you to release the data back. This is the popular method used by malware authors to extract money from organisations or individuals. Different ransomware varieties are used to get on to a person’s computer, but the most common technique is to install a software or use social engineering tactics, like displaying fake messages from law enforcement department, to attack on a victims computer. The criminals do not restore the computer access until the ransom is paid.
Ransomware is very scary as the files once damaged are almost beyond repair. But you can overcome this attack if you have prepared your system. Here are a few measures that will help you to protect your organisation from the attack.
To defeat ransomware, it is important to regularly backup your data. Once you get attacked, you will lose all your documents; but if you could clean your machine, restore your system and other lost documents from backup then you need not worry. So backup the files to an external hard drive or backup service, then you should can turn off your computer and start over with a new setup after attack.
Use Reputable Security Precaution
Using both antivirus software and a firewall will prevent you. It is critical to keep the software up-to-date and maintain a strong firewall, otherwise the hacker might easily exploit through security holes. Also purchase antivirus software from a reputable company because there are many fake software.
Ransomware Awareness Training
It is important to be aware of the cyber security issues and get properly trained to identify the phishing attempts. Creating awareness to staffs will help them to take action and deal with the ransomware. As the methods used by hackers constantly change it is necessary to keep your users up-to-date. Also, it is tough for untrained users to question the origin of a well-crafted phishing email. So, providing security training to staffs is the best way to prevent malware infection through social engineering.
Disconnect from Internet
If you are suspicious about a file or receive a ransomware note then immediately stop communicating with server. By disconnecting from the internet you might lessen the damage, as it takes some time to encrypt all your files. This isn’t foolproof but disconnecting from internet is better than nothing. As you can always re-install software if you have backed up your data.
Check File Extensions
Always see the full file extension, it helps to easily spot suspicious files. If possible try to filter the files in your mail by extension, like you can deny mails sent with ‘.EXE’ files. In case you exchange .EXE files in your organisation then it is better to use ZIP files with password-protection.
Exercise Caution, Warn Authorities, Never Pay
Avoid any links inside emails and suspicious websites. It is better to use another computer to research details if your PC falls under attack. Also, inform the local FBI or cybercrime about the attack. Finally, never pay them as it would be a mistake because they may continue to further demand from you and will not release your information as well. So, taking precautions to protect your data and being alert are the best ways to prevent ransomware attack.
In reality, dealing with ransomware requires an effective backup plan so you could protect your organisation from the attack.
