5 Tips to Prevent Ransomware Attacks in your Business

The ransomware attacks, a data-hijacking malware, previously known as a threat to online security for home users and small businesses, are now confirmed as a popularized threat. To get an idea of the size of the problem, in Latin America, Brazil is the leader in this type of attacks and the fourth in the world, according to the study by Kaspersky Lab. These attacks happen through the delivery of e-mails, spam or phishing, and the users are deceived when clicking on the malicious links, leaving the systems, devices, and files inaccessible until some type of payment is made. It is a hijacking of the information. To protect company data and assets from such attacks, organizations must adopt security measures for cyber attacks that include the entire infrastructure, from storage to mobile networks. Specialists point out that these types of attacks were increasingly successful because one in three security professionals is willing to pay for data recovery. The numbers are even higher when respondents are professionals whose companies have been targeted by ransomware attacks. However, what can your company actually do to protect itself? Here are tips to prevent your business from ransomware:

1. Make a copy of your data in backup
One of the first indications is always to make a backup of your data. There are many ways to do them automatically, from an external server or even options for automatic configurations in the cloud. These services can protect you and your company in the event of a physical disaster, such as earthquakes, fires and other acts of nature. If this option is not automatic, ideally there should be a calendar scheduled to remind you when the last backup was performed. Ideally, it should be done weekly, at least.

2. Attention to the emails always check the origin of e-mail messages
If in doubt, it is best to always check with the sender who sent you the message and avoid opening attachments. Beware of e-mails with similar senders. A simple change of a letter in the address of the person who sent you may be a sign that it is a message with bad intentions.

3. Educating the users for the cases of phishing
It is important that users become aware of the tactics used in those mechanisms that can lead people to click on malicious links and attachments. In that case, teaching good Internet browsing practices and using e-mails is a great ally to avoid falling into those traps. Moreover, that approach can be in many ways, such as tutorials or even make employees aware through training. Inform the team of recent attacks and how they can appear on machines, ask them not to click and not share information that they are unclear about if they are safe. Officials, in that case, end up acting as vigilantes and are more attentive in phishing identification, as they can come from several reliable sources, such as a friend, a co-worker or even a favorite store of the user.

4. Software Update
 Adopt a secure computer Update software, software, and applications, as one of the techniques used by ransomware authors, is to explore vulnerabilities in popular software applications such as Adobe Reader, Adobe Flash, Java, Google Chrome, iTunes, Skype, and Firefox. Always update the latest version of those applications, as they offer you protection from online threats.

5. Control access, limit access, and share data
Keep work data and personal data in separate files and do not allow family members to use devices that are used on the job. Such simple precautions can minimize threats. If you have already been exposed to an attack, the ideal thing is to disconnect to prevent this malware from spreading to other systems or even other devices.
