Recently, several corporations around the world have been victims of hacker attacks, including Brazilian government websites.
Among the various victims reported, we can mention PlayStation Network, Telefónica and even the Barretos Cancer Hospital. In addition, the FBI and NASA have also been hack victims.
Considering that large institutions such as those mentioned have already suffered from the action of hackers, it is possible that your company is also vulnerable to attacks.
Generally, the method most used by hackers to attack companies is the Distributed Denial of Service (DDoS) — or Denial of Service Attack, in Portuguese translation.
This type of attack, unlike what is imagined by many, does not directly use the attackers' machines. The process takes place in another way, using company servers and personal computers.
With news of cyber attacks being seen more often and in more places, like the one brought down systems of public agencies and companies around the world, it's important to make sure your business is protected.
So, here are the top tips on how to avoid being another victim of criminals.
When you fall victim to a ransomware attack, the biggest direct damage you can take is the loss of files, since, until a ransom is paid, the virus encrypts them. It is worth remembering that victims do not always have their documents decrypted even after payment.
In this case, the best alternative is to store the files on a completely independent system, such as an offline hard drive or a secure storage system. cloud backup, for example. Generally, companies save copies of this data on external servers so that they cannot be affected in the event of an attack on the company's network.
To infect machines using ransomware, cybercriminals need to install malicious software on the victim's equipment, initiating the attack.
The most used way is via phishing emails, malicious advertisements on websites and suspicious programs and applications.
Therefore, care must be taken when opening websites and emails from suspicious sources, as well as avoiding downloading software that has not been verified by an official store or specialized company.
Also, it is recommended to read the review and information about the software before installing it.
Antivirus systems manage to prevent ransomware from being downloaded onto a machine, in addition to identifying them in case they are somehow transferred to the computer.
Most software in this category can review files for malicious code before the download is complete. They can also block the installation of secret programs that do not ask for user authorization.
Users need to be aware of operating system updates made available by manufacturers, so that the number of breaches and the installation of undesirable programs can be reduced.
Therefore, it is very important to have the latest versions of software as soon as they are available.
It is critical that victims never pay the ransom amount that hackers demand. In addition to the fact that there is no guarantee that the criminals will comply with the agreement and return your files, this attitude will certainly serve as an incentive for future attacks.
Experts recommend that you check to see if your email address — or that of your company — is on an internet leak list. According to Rafael Zanatta, an expert at Idec, this needs to be the first step.
For this, there is a free and secure tool, developed by Troy Hunt, — data security expert and Microsoft MVP — called Have I Been Pwned.
The website is able to check if your email address is on any list of hacked accounts in recent times. In addition, it is possible to create an automatic notification in case the given address appears in any leak list in the future.
If the email account in question is on a list of leaks, urgently change the password on all services that use that address.
For this, use strong and unique passwords, mixing letters, numbers and, who knows, even special characters such as dollar signs, exclamation marks, among others. Also, it is recommended to think of random phrases rather than words and not use the same password for multiple online services.
