Most common and high risking cyber security threats that are on a alarming phase

Cyber attacks are exploitations of those vulnerabilities, just as pollution was a side effect of the Industrial Revolution, so are the many security vulnerabilities that come with increased Internet connectivity. For the most part, individuals and businesses have found ways to counter cyber attacks using a variety of security measures. This article will focus on cyber security risks. We'll look at eight of the most frequent cyber security dangers that your company may encounter, as well as how to avoid them.

So before we jump into the session let me give you how the session will work we are going to discuss the most eight common cyber threats we’re going to discuss in particular what they are how the threat works and how to protect yourself. So let’s jump in now cyber attacks are taking place all the time even as we speak the security of some organizations big or small is being compromised for example if you visit the site out here that is a threat cloud you can view all the cyber attacks that are happening right now.

To begin, we'll look at malware, which is an umbrella word for a wide range of cyber threats such as Trojans, and Viruses. Malware is simply described as computer code that has a malevolent aim, such as stealing data or destroying files. The manner malware goes about causing harm might assist you to figure out what sort of virus you're dealing with. So, first and foremost, viruses, like their biological namesakes, attach themselves to clean files and infect other clean files, and they can spread uncontrollably, causing damage to the system's core functionality as well as deleting or corrupting files. Viruses typically appear as executable files.

If you might have downloaded from the internet then there are also Trojans now this kind of malware disguises itself as legitimate software or is included as illegitimate software that can be tampered with it tends to act as backdoors in your security to let others malware in. Then we have worms, entire networks of devices either local or across the internet by using the network’s interfaces it uses each consecutive infected machine to infect more.

Then we have bonnets and such where botnets are networks of infected computers that are made to work together under the controller of an attacker. So basically you can encounter malware if you have some OS vulnerabilities or if you download some pirated software from somewhere, or if you have some other email attachment that was compromised.

So how exactly do you remove malware or how exactly do you fight against it well each form of malware has its way of infecting and damaging computers and data. So each one requires a different malware removal method, the best way to prevent malware is to avoid clicking on links or downloading attachments from unknown senders, and this is sometimes done by deploying a robust and updated firewall. Which prevents the transfer of large data files over the network in the hope to weed out attachments that may contain malware, it's also important to make sure your computer's operating system whether it is Windows Mac OS Linux uses the most up-to-date security updates.

Moreover, software programmers update programs frequently to address any holes or weak points and it’s important to install all these updates as well as to decrease your system weaknesses so next up on our list of cyber threats. We have phishing so what exactly is phishing well often posing as a request for data. Third-party phishing attacks are sent via e-mail and ask users to click on a link and enter their data.

Phishing emails have gotten much more sophisticated recently and making it difficult for some people to discern a legitimate request for information from a false one now phishing emails often fall into the same category as spam but are way more harmful than just a simple ad so how exactly does phishing book. Well, most people associate phishing with an email message that spoofs or mimics bank credit card companies or other businesses like Amazon eBay and Facebook. These messages look authentic and attempt to get victims to reveal their personal information but email messages are only one small piece of a phishing scam from beginning to end.

The process involves five steps the first step is planning, the fissure must decide which business to target and determine how to get email addresses for the customers of that business then they must go through the setup phase once they know which business to spoof and who their victims are. Fisher's create methods for delivering the messages and collecting the data then they have to execute the attack and this is the step most people are familiar with.

That is the Fishers end the phony message that appears to be from a reputable source. After that the Fisher records the information the victims enter into the webpage or pop-up windows and in the last step which is identity theft and fraud. The Fisher's use the information they've gathered to make illegal purchases or otherwise commit fraud and as many as 1/4 of the victims never fully recover.

So, how exactly can you be preventing yourself from getting fished well the only thing that you can do is being aware of how phishing emails work. So first of all a phishing email has some very specific properties. So firstly, you will have something like a much generalized way of addressing someone like your client then your message will not be actually from a very reputable source. You should report this email to your administrators or anybody else that you think is supposed to be concerned with this.

Also let me share that a quick demonstration on how phishing works from the perspective of an attacker so first of all I have created a phishing website for harvesting Facebook credentials. I simply just took the source code of the Facebook login page and pasted it and then made a back-endc ode in PHP which makes a log file of all the Facebook passwords that get entered onto the phishing page. Now I've also sent myself an email as to make sure this looks legitimate but this is only for spreading awareness so please don't use this method for actually harvesting credentials that's a very illegal thing to do

So let's get started first of all you will go to your email and see that you get some email saying that our Facebook credentials have been compromised. So when you open it, it looks pretty legit. The point out here is to make you feel as if it is real and from the official side. We have strong reasons to believe that your credentials may have been compromised and might have been used by someone else we have locked your Facebook account please click here to unlock, sincerely Facebook associate team.

So if we click here we are redirected to a nice-looking Facebook page which is exactly how Facebook looks like. When you're logging in, now suppose I were to log into my Facebook account which I won’t I’ll just use some random ID like this is an email address email com and let’s put password as admin one two three and we click login now since my Facebook is already logged in. It'll just redirect to facebook.com and you might just see me logged in but on a normal computer it'll just redirect you to “www.facebook.com” which should just show this site again.

Okay so once I click login out here, all that the backend code that I've written in PHP out here will do is that it's going to take all the parameters that have entered into this website. That is my email address and password and just generates a log file about. So this is how exactly phishing works you enter an email address and you're entering the email address on a phishing website and then it just redirects you to the original site, but by this time you’ve already compromised your credentials.

So always be careful when dealing with such emails so now jumping back to our session the next type of cyber attacks we are going to discuss is passing with the docs. So an attempt to obtain or decrypt user's password for illegal use is exactly what a password attack is. Hackers can use cracking programs dictionary attacks and password sniffers and password attacks password cracking refers to various measures used to discover computer passwords. This is usually accomplished by recovering passwords from data stored in or transported from a computer system.

Password cracking is done by either repeatedly guessing the password usually through a computer algorithm in which the computer tries numerous combinations until the password is successfully discovered. Now password attacks can be done for several reasons but the most malicious reason is to gain unauthorized access to a computer with the computers.

Owners awareness not being in place now this results in cybercrime such as stealing passwords to access bank information now today there are three common methods used to break into password-protected system. The first is a brute-force attack a hacker uses a computer program or script to try to login with possible password combinations usually starting with the easiest to guess password. So just think if a hacker has a company list, he or she can easily guess user names if even one of the users has a password one two three. She/he will quickly be able to get in.

Next comes the dictionary attacks, now a hacker uses a program or script try to login by cycling through the combinations of common words in contrast with brute-force attacks. Where a large proportion key space is searched systematically, a dictionary attack try is only those possibilities which are most likely to succeed typically derive from a list of words. For example, a dictionary generally dictionary attacks succeed because most people tend to choose passwords which are short or such as single words found in the dictionaries or simple easy predicted variations on words such as appending a digit also.

Now, the last kind of password attacks are used by key logger attacks a hacker uses a program to track all of the user's keystrokes so at the end of the day everything the user has typed including the login IDs and passwords have been recorded. A key logger attack is different than a brute-force or dictionary attack in many ways not the least of which the key login program used is a malware that must first make it onto the user's device and the key logger attacks are also different because stronger passwords don't provide much protection against them. Which is one reason that multi-factor authentication is becoming a must-have for all businesses and organizations.

Now the only way to stop you from getting killed in the whole password attack conundrum is by actually practicing the best practices that are being discussed in the whole industry about passwords. So, you should update your password regularly, you should use alpha numeric’s in your password, and you should never use words that are actually in the dictionary. It's always advisable to use garbage words that make no sense for passwords. As they just increase your security.

So moving on we're going to discuss “DDoS attacks”, so what exactly is a DDoS or a DOS attack. Well first of all it stands for distributed denial of service and a dos attacks focuses on disrupting the service to a network as the name suggests attackers send high volume of data of traffic through the network until the network becomes overloaded and can no longer function. So there are a few different ways attackers can achieve dos attack, but the most common is the distributed denial of service attack. This involves the attacker using multiple computers to send the traffic or data that will overload the system. In many instances a person may not even realize that his or her computer has been hijacked and contributing to the DOS attack.

Now disrupting services can have serious consequences relating to security and online access many instances of. Large-scale dos attacks have been implemented as a single sign of protests towards governments or individuals and have led to severe punishment including major jail time. So, how can you prevent dos attacks against yourself?

Firstly, unless your company is huge it's rare that you would be even targeted by an outside group or attackers for a DOS attack. Your site or network could still fall victim to one. However, if another organization on your network is targeted, now the best way to prevent an additional breach is to keep your system as secure as possible.

With regular software updates online security monitoring and monitoring of your data flow to identify any unusual or threatening spikes in traffic before they become a problem. These attacks can also be perpetrated by simply cutting a table or dislodging a plug that connects your website server to the Internet, so due diligence in physically monitoring your connections is recommended as well. Okay, so next upon a list is a man-in-the-middle attack, so by impersonating the endpoints in an online information exchange.

The man-in-the-middle attack can obtain information from the end user and the entity he or she is communicating with. For example, if you are banking online the man in the middle would communicate with you by impersonating your bank and communicate with the bank by impersonating you.

The man in the middle would then receive all of the information transferred between both parties which could include sensitive data such as bank accounts and personal information. So, how does it exactly work, normally hacker gains access through an on encrypted wireless access point which does not use “WEP” or “WPA” or any of the other security measures. Then they would have to access all the information being transferred between both parties by actually spoofing something called “Address Resolution Protocol” that is used when you are connecting to your gateway from your computer.

So how can you exactly prevent such attacks from happening against you? Firstly, you have to use an encrypted WAP that is an encrypted wireless access point next you should always check the security of your connection because when somebody is trying to compromise your security. The user will try to strip down the SC DPS or SSD’s that is being injected in the website. Which are the security protocols so if something likes this HTTPS is not appearing in your website, you're on an insecure website where your credentials or your information can be compromised.

The last and the final measure that you can use is by investing in a virtual private network which spoofs your entire IP and you can just browse the Internet with perfect comfort. Next up on our list is drive-by downloads, so gone are the days where you have to click to accept a download or install a software update to become infected. Now just opening a compromised webpage could allow dangerous code to install on your device.

You just need to visit or drive by a webpage without stopping or to click accept any software add the malicious code can download in the background to your device a drive-by download refers to the un-intentional download of a virus or malicious software onto your computer or mobile device. A drive-by download will usually take advantage or exploit a browser or app or operating system that is out of date and has security flaws this initial code that is downloaded. It is often very small and since this job is often simply to contact another computer of where it can pull down the rest of the code onto your smart phone tablet or other computers often a web page will contain several different types of malicious code in hopes that one of them will match a weakness on your computer.

So, how does this exactly work well? First you visit the site and during the 3-way handshake connection of the “tcp/ip” protocol a back end script is triggered. As soon as a connection is made while the last ACK packet is sent, a download is also triggered and the malware is injected into your system. Now, the best advice I can share about avoiding drive-by downloads is to avoid visiting websites that could be considered dangerous or malicious this includes adult content file sharing websites or anything that offers you a free trip to the Bahamas. Now some other tips to stay protected include keep your internet browser and operating system up-to-date. Use a safe search protocol that warns you when to navigate to a malicious site and use comprehensive security software on all your devices, keeping it up to date. Okay, so that was it about drive-by downloads.

Next up is malware via advertising, which intentionally infect people and businesses these can be any ad on any site often ones which you use as a part of your everyday internet usage and it is a growing problem. As is evident by a recent US Senate report and the establishment of bodies like trust in ads now whilst the technology being used in the background is very advanced the way it presents to the person being infected is simple to all intents and purposes. The advertisement looks the same as any other but has been placed by. Criminal now without your knowledge a tiny piece of code hidden deep in the advertisement is making your computer go to the criminal servers these and catalog details about your computer and its location before choosing which piece of malware to send you and this doesn't need a new browser window and you won't know about it. So, you're redirected to some criminal server the malware injection takes place and you're infected. It's a pretty dangerous thing.

So, how exactly can you stop magnetizing, well first of all you need to use an ad blocker which is a very must in this day and age you can have ad blocker extensions installed on your browser whether it be Chrome Safari or Mozilla. Also regular software updates of your browser and other software's that work peripheral to your browser always help. Next is some commonsense any advertisement that is about lottery that's offering you free money is probably going to scam you and inject malware too. So, never click on those ads, so the last kind of cyber-attacks we are going to discover is rogue software. So, rogue security software is a form of malicious software and Internet fraud that misleads users into believing that there is a virus on their computer and manipulates them into paying money for a fake malware removal tool. It is a form of scare that manipulates users through fear and a form of ransomware rogue security software has been a serious security threat in desktop computing since 2008.

So, now how does rogue security software book these scams manipulating users into download the program through a variety of techniques? Some of these methods include ads offering free or trial versions of security programs. Often pricey upgrades are encouraging, the purchase of the deluxe versions then also pop-ups warning that your computer is infected with the virus which encourages you to clean it by clicking on the program and then manipulated SEO rankings that put infected website as the top hits when you search these links then read directly to a landing page that claims your machine is infected and encourages you a free trial of the rogue security program. Now once the scare ware is installed it can steal all your information slow your computer or corrupt your files, disable updates, limit antivirus software or even prevent you from visiting other websites, and security software vendor sites.

While talking about prevention the best defense is a good offense and in this case an updated firewall makes sure that you have a working one in your office that protects you and your employees from these type of attacks it is also a good idea to install a trusted antivirus or anti-spyware software program that can detect threats like these and also a general level of distrust on the internet and not believing anything right off the bat is the way to go ok. So, that was all about the different types of cyber threats and how they work and how you could prevent them I also hope you enjoyed the article.
