Ransomware attacks<\/b> are a serious threat to businesses and individuals across the globe. They\u2019re extremely effective, costing companies worldwide millions of dollars every year. However, that doesn\u2019t mean you\u2019re powerless in preventing these attacks. Steps can be taken to minimize the damage and protect yourself and your business from ransomware.<\/span><\/p>\n\n\n\n

Read on to find out identification methods, preparation tactics, and <\/span>how to prevent ransomware attacks<\/b>.<\/span><\/p>\n\n\n\n

Ransomware Definition<\/h2>\n\n\n\n

What is a ransomware attack<\/b>? Ransomware is defined as a form of malware that locks and encrypts a victim\u2019s data, holding it hostage with a key that only the attacker has access to. This can range from an automated virus that returns data once payment has been received or a specific demand realized, to a simple encryption virus that the attacker manually releases once they\u2019ve received what they want. <\/span>Ransomware attacks<\/b> as a whole are extremely dangerous and exceedingly effective.<\/span><\/p>\n\n\n\n

Ransomware Types<\/h3>\n\n\n\n

While there\u2019s no limit to variations of this attack type, ransomware generally falls into three primary categories.<\/span><\/p>\n\n\n\n

Locker Ransomware<\/h4>\n\n\n\n

Locker ransomware completely shuts down and blocks access to vital systems. These viruses can make a computer impossible to access. The most common  types create a pop-up that blocks access to the system. A message conveying urgency then appears. It\u2019s usually something along the lines of \u201cthe device was used to visit sites with \u201cillegal content.\u201d A fine must be paid in order to restore access.\u201d<\/span><\/p>\n\n\n\n

Crypto-Ransomware<\/h4>\n\n\n\n

Crypto-ransomware is another common type of ransomware that spreads rapidly, encrypting important files. While it doesn\u2019t block access to the entire system, attempting to access the infected files triggers a similar pop-up demanding a fee.<\/span><\/p>\n\n\n\n

Double Extortion Ransomware<\/h4>\n\n\n\n

Double extortion ransomware is essentially a blackmail virus. It encrypts files and sends the uncorrupted versions to the attacker. When someone attempts to access the files, they\u2019re met with a demand for a fee, similar to crypto-ransomware. However, the key difference is that the attacker threatens to publicly release or publish the stolen data if the demands aren\u2019t not.<\/span><\/p>\n\n\n\n

How Do Ransomware Attacks Work?<\/h2>\n\n\n\n

Now that we\u2019ve covered the different types, it\u2019s time to take a deeper look into ransomware. How do these attacks start, and<\/span> how does ransomware work<\/b>?<\/span><\/p>\n\n\n\n

Where Do Ransomware Attacks Come From?<\/h3>\n\n\n\n

Ransomware is an advanced virus created by hackers like any other sort of malware. However, a <\/span>ransomware attack<\/b> doesn\u2019t use an entirely new virus. While they may change and evolve, overall ransomware consists of a few different widely-used malicious software (Bad Rabbit, Cryptolocker, Petya, Locky, and Jigsaw, to name a few).<\/span><\/p>\n\n\n\n

These forms of malware can be picked up and used by just about anyone\u2014not only skilled hackers. This is what makes ransomware so dangerous. As more and more people get their hands on it, it\u2019s becoming more and more prevalent. Even business models involving selling ransomware exist, but more on those below.<\/span><\/p>\n\n\n\n

How Does Ransomware Spread?<\/h3>\n\n\n\n

While it depends on the ransomware type, the infection methods are all relatively similar. Most ransomware is initially delivered to a device through an email or a message. Once you inadvertently interact with it, the virus takes hold\u2014similar to any other malware. <\/span><\/p>\n\n\n\n

Once its roots are planted, ransomware starts looking for the most valuable data to collect and encrypt. It also searches for any other systems connected to its current root system in order to spread further and have access to a greater data pool.<\/span><\/p>\n\n\n\n

Once it has a sufficient data collection of valuable data under its grasp, the ransomware locks down. Most ransomware won\u2019t risk detection by locking data immediately, so it\u2019ll attempt to spread as far as it can before encrypting and locking files. However, this isn\u2019t exactly much of a grace period where the system is safe. Most ransomware spreads extremely quickly.<\/span><\/p>\n\n\n\n

What is Ransomware Detection?<\/h2>\n\n\n\n

As you probably guessed, the faster you find the malware, the better. Early detection is key for an efficient response to any ransomware attacks. It gives you more time to decide on the appropriate response while relieving the risk of infection spreading indefinitely. Ransomware detection typically works in three ways:<\/span><\/p>\n\n\n\n

By Signature<\/h3>\n\n\n\n

Signature detection is the most simple of the three. It compares the signature of incoming files and data with its own library to see if it recognizes and trusts the signature However, this form is quickly becoming less useful as malware evolves. Ransomware is being built and adapted to \u201ccloak\u201d its signature and pass under the radar.<\/span><\/p>\n\n\n\n

By Behavior<\/h3>\n\n\n\n

Behavior detection watches any new file activity to see if any actions are similar to malware processes. This detection is useful because ransomware often has obvious strange behavior compared to normal files. Any files attempting to interact with other files on the system without reason are flagged as suspicious.<\/span><\/p>\n\n\n\n

By Abnormal Traffic<\/h3>\n\n\n\n

Rather than a single system, abnormal traffic detection watches the entire network for signs of anything strange. Out-of-place traffic for various systems on the network, such as rapid data jumping from system to system is reported. This prevents ransomware from slipping across devices undetected.<\/span><\/p>\n\n\n\n

How to Prevent Ransomware Attacks?<\/h2>\n\n\n\n

Here we\u2019ll cover <\/span>how to prevent ransomware attacks<\/b> before they happen. This is the best-case scenario, as stopping such an before infection starts is the only way to ensure utter safety.<\/span><\/p>\n\n\n\n

Prevention tips for ransomware<\/span><\/a> are similar to other malware mitigation methods. Use trusted, updated antivirus software to keep your devices protected and clean. Employ the use of a trusted VPN service<\/a> for better control of who has a hold of your network IP. And, of course, interact with emails and attachments cautiously, especially those from unknown senders.<\/span><\/p>\n\n\n\n

However, with ransomware, in particular, it\u2019s <\/span>extremely<\/span><\/i> vital to keep backups of important files stored on separate systems. That way, even in the event of a total system lockdown, you aren\u2019t helpless to retrieve your encrypted files. Having up-to-date backups on the same system can be helpful, yes. But it also runs the risk of ransomware encrypting your backups as well, or even locking down the whole system, rendering the backups useless.<\/span><\/p>\n\n\n\n

How to Stop Ransomware in Action?<\/h2>\n\n\n\n

While it\u2019s much more difficult to <\/span>fight against ransomware in action<\/span><\/a>, it\u2019s not impossible. There are a few immediate steps you can take to avoid further damage:<\/span><\/p>\n\n\n\n

Isolate any infected devices and disconnect them from the network ASAP. This will stop the virus from spreading to other hardware. It also prevents the ransomware from seeking new devices to infect.<\/span><\/p>\n\n\n\n

Now, begin looking into the damages. See what was infected, what was lost, and try to find where the infection started.<\/span><\/p>\n\n\n\n

Establish what data was breached and whether you have uncorrupted backups. In a best-case scenario, you may have enough healthy backups that nothing important was lost. However, this isn\u2019t usually the case.<\/span><\/p>\n\n\n\n

Once you\u2019ve figured out how bad the damage is, it\u2019s time to do some research. Figure out what strain of ransomware you\u2019ve been hit with. This will determine how you go about handling the matter. Some strains are easier to recover from than others.<\/span><\/p>\n\n\n\n

Some websites and online services offer decryption tools for free for victims of <\/span>ransomware attacks<\/b>. While they don\u2019t work for every attack, it\u2019s certainly worth looking into. And in a worst-case scenario, if all else fails, you\u2019ll need to decide how you\u2019ll respond. You can either meet the demands and hope they honor their end of the deal or simply let the lost data go.<\/span><\/p>\n\n\n\n

What is Ransomware as a Service (RaaS)?<\/a><\/h2>\n\n\n\n

Similar to the popular \u201cSoftware as a Service (SaaS)\u201d business model, Ransomware as a Service (RaaS) is a term for subscription-based ransomware. The ransomware virus is pre-developed, and the attacker uses it to force companies and individuals to pay the ransom. On any successful payouts, the attacker and the developer of the ransomware share the profit.<\/span><\/p>\n\n\n\n

This service is a growing danger to companies, as it allows dangerous malware to fall into the hands of just about anyone with an internet connection.<\/span><\/p>\n\n\n\n

Why Shouldn\u2019t I Just Pay the Ransom?<\/h2>\n\n\n\n

It\u2019s estimated that about <\/span>83% of all ransomware victims<\/span><\/a> meet the demands of the attacker and pay the ransom. It\u2019s not hard to see why. When your important files and data are held hostage and you\u2019re given a short timeframe to respond, it\u2019s easy to make unwise decisions to deal with the situation. But why shouldn\u2019t you meet the demand? What if all that corrupted data is well worth the money being demanded?<\/span><\/p>\n\n\n\n

Unfortunately, ransomware attackers aren\u2019t exactly saints bound to their word. Not every ransomware strain automatically unlocks once payment is made. The attacker usually has some sort of say whether the lock comes off or not. And all too often, it doesn\u2019t.<\/span><\/p>\n\n\n\n

Meeting these demands won\u2019t always guarantee the safe return of your data. More often than not, these actions just tell the hacker that you and your company are willing to bend a knee to recover what\u2019s stolen\u2014which isn\u2019t a good reputation to have.<\/span><\/p>\n\n\n\n

Can Ransomware Infect Cloud Storage Solutions?<\/h2>\n\n\n\n

Recent years have seen more and more ransomware built specifically to infect cloud infrastructures. The cloud is no longer impenetrable when it comes to ransomware viruses. In fact, some of the new ransomware strains built for the cloud actually spread faster than most other versions, meaning cloud users should be extra cautious when it comes to malware like this.<\/span><\/p>\n\n\n\n

Are Ransomware Attacks Increasing?<\/h2>\n\n\n\n

In short, yes. As more and more individuals and groups get their hands on this kind of malware, the number of <\/span>ransomware attacks<\/b> on a yearly basis is increasing. Pair this with the world\u2019s recent transition of companies taking their businesses online, and hackers have all the more reason to step up their game.<\/span><\/p>\n\n\n\n

Ransomware attacks<\/b>, both small-scale and large-scale, are growing more and more common. And while the means of defense and prevention against these attacks are evolving as well, it takes extreme caution and care from business owners to defend themselves and their team from such attacks.<\/span><\/p>\n\n\n\n

Is There a Single Solution Against Ransomware?<\/h2>\n\n\n\n

Like with most malware, no. There\u2019s no magic shield that keeps ransomware from ever getting into your company\u2019s systems. However, a combination of safety measures, common sense, and taking online precautions proves more than effective in reducing your network\u2019s chances of being infected with ransomware and falling prey to an attacker\u2019s demands.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
