Ransomware is a type of malicious software that denies access to your data or threatens to publish or delete it until a ransom is paid. It’s called ransomware because the hacker “ransoms” your data by demanding money in exchange for its return.
Ransomware typically propagates as an email attachment, but can also come from drive-by download attacks on unpatched websites or other malware. Once run, it encrypts all files on the computer and then displays a message stating that those files have been encrypted and demanding payment to decrypt them.
The most common form of ransomware locks down users' computers with strong encryption, preventing access even to the user's own administrator account.
1. Keep your antivirus up to date and run it regularly
In addition, make sure that you also have a firewall enabled on all of your devices. This will help prevent unauthorized strangers from accessing the networks in your home or office, which could potentially lead to their downloading ransomware onto your device without you knowing.
2. Make backups! Ransomware can be very difficult for IT professionals to remove because once an infection takes hold, it locks the PC down so tight that even system administrators might not be able to get to data directories where user files are stored in order to restore them from backup copies.
3. Pay attention to what you download
Check the file extensions of any attachments that are sent to you before opening them, not all .exe files are malicious! Sometimes hackers attach a .txt or .jpg file extension to an executable in order to fool users into thinking it is not dangerous.
4. Avoid using the same password for multiple user accounts
If a hacker gets your password to your email or online banking account, they could potentially get access to everything you have!
5. Be smart when browsing the Internet
Do not visit suspicious looking websites, they may contain malicious code that can infect your computer with ransomware or other cyber threats. Make sure to always keep your operating system and application software up to date in order to minimize the chances of being hit with ransomware or any other type of malware!
One of the biggest cyber security concerns for businesses is ransomware. This type of malicious software locks access to computers, rendering them virtually useless until a fee is paid to unlock them.
After an attack, business owners are often left with no data and no way to get their files back without paying some sort of ransom fee that can cost thousands of dollars.
The best way to prevent ransomware attacks is staying informed about the latest cyber security trends and taking measures to protect your business.
As more businesses go online, there has been an increase in cyber crime activity. Cyber criminals are finding new ways to attack both public and private computer systems all over the world, including in your city or town.
This article will discuss the latest ransomware attacks, how to prevent them from taking place and what measures you can take to protect your business.
According to a cyber security analyst at Kaspersky Lab, a Russian software company that provides cyber security products, about 75% of all ransomware infections target businesses rather than individuals.
They also found that one business is attacked with ransomware every 40 seconds and the average ransom fee is $16,000.
Just last year, a Los Angeles hospital was forced to pay $17,000 after an employee opened a phishing email containing ransomware on their computer.
This particular attack locked access to all of the hospital's medical records, preventing doctors from accessing patients' information. They were forced to revert back three days in time to avoid other critical issues.
Ransomware attacks are even more prevalent now than they were last year due to an increase in sophisticated malware that has adapted over the years and continues to grow in popularity among cyber criminals.

Cyber security threats are a rapidly growing issue for businesses as hackers begin to take advantage of the lack of cybersecurity knowledge from business owners. Ransomware is one such cyber security threat that has been on the rise over the past several years and is becoming increasingly common in 2018 alone.
Ransomware locks up a user's files or otherwise prevents them from using their. Cyber criminals can create ransomware, install it onto unsuspecting user's computers, and then demand payment in the form of Bitcoin or other cryptocurrency to unlock the files which have been trapped up (i.e., encrypted). The average ransom amount is between $300-$400 according to the FBI Internet Crime Complaint Center; however, individuals have been hit with much higher ransom amounts.
To prevent ransomware, keep software updated on your computer(s), do not open unsolicited emails, and utilize backups to recover files after being hit by this type of malware.
Step 1: Make sure that Office applications are closed. This is the main way that Ransomware can get into a system or network, through an Office application.
Step 2: Be wary of new updates from Microsoft. As soon as new updates become available for Office products, apply them immediately to mitigate any risk of infection from Ransomware.
Step 3: Use a good antivirus and firewall program, and keep them up-to-date. Make sure that the programs are always turned on and set to automatically update. This is just as important as the first step.
Step 4: Ensure that all Windows Updates have been applied and that patches are always up-to-date. Be sure to have the most current updates available for all Windows products, as well as any other software that is used on a system or network.
Step 5: Use strong passwords and change them often. Do not use the same password for multiple accounts, and make sure they are long and complex. A good way to create a password is to come up with a phrase and use the first letter of each word as the password. For example: "Thisisareallylongpassword" could be changed to TiaLrsp.
Step 6: Make sure that all employees are educated on how Ransomware works, and what the methods of infiltration are. This will help them to identify suspicious behavior or software.
Step 7: Be sure that all employees are aware of social engineering tricks, and what these types of scams look like. The more education on cybersecurity the better.
These seven steps will prevent Ransomware from infecting a system or network. To ensure that data is secured after a ransomware attack, a company should have data backups that are stored in a location not connected to the network. This will ensure that even if Ransomware encrypts the data on a system or network, the backup files remain unencrypted and available for recovery.
And it is no wonder; with an increasing number of hacking cases and data breaches leading to financial and identity theft, Internet criminals are finding innovative ways to exploit the vulnerabilities of companies' cyber security systems.
One such increasingly popular method of attack is ransomware – a type of malware that locks you out of your own computer and threatens to delete all your data and documents until you pay a ransom fee.
Experts suggest that ransomware attacks will only increase in the future, impacting companies both small and large across many sectors of business.
If you want to prevent ransomware from affecting your business then it is important that you understand what ransomware is and how it operates.
The term ransomware may sound intimidating, but it is actually relatively simple in its operation. Data thieves begin by finding the security gaps in your business's cyber security system. They then exploit these vulnerabilities to install ransomware onto your computer systems and lock you out until you pay a ransom fee to restore access. More often than not, paying this ransom fee is simply handing over your hard earned cash to criminals that will continue to run ransomware attacks on other businesses.
So what can you do to prevent this? The key thing is education. Once you understand how ransomware works and what it does, you can begin making the necessary steps towards protecting yourself and your business from an attack.
Knowledge is power, and this applies to knowing how ransomware attacks your business just as much as it applies to understanding the ins and outs of owning a business.
It is important that you educate yourself on what ransomware is, what are the most common types of infection vectors, how ransomware infiltrates systems, where are they usually hidden, how can you remove them, and what are the best practices in protecting your business against ransomware.
These are all important questions that you should be asking yourself, because it is only when you know the answers to these questions that you can begin taking steps towards preventing ransomware from infiltrating your network.
1. Back up your data regularly and keep a backup copy off-site. Make sure that this is a reliable backup service that you trust, as it may be the only thing standing between you and a successful ransomware attack.
2. Educate yourself on how ransomware works and how it affects your business. This way you can learn to prevent ransomware from infiltrating your systems in the first place.
3. Make sure that you use strong passwords for all user accounts, but especially for administrator accounts on computers and servers. Never reuse the same password across multiple accounts, and also make sure that you never write down passwords in public places.
4. Use a commercial antivirus software to protect your network from malware, spyware and ransomware downloads.
5. Secure remote access to the business's internal networks and computers (e.g., via VPN), and use multi-factor authentication for all external services that support it (e.g., Gmail).
6. Educate all employees on how ransomware works and how it affects your business, so that everyone can take part in preventing a successful attack.
7. Be careful when opening documents received from users of other systems, unless you are certain that they come from a trusted source.
