10 Cybersecurity Myths

Myth1.png

A new infographic by Varonis, titled “10 Cyber Security Myths Putting Your Business at Risk” identifies what is the myth and what is the reality. If you are like most small business owners, you probably aren’t a digital security expert. So, having a look at this infographic may be the best way to identify weaknesses in your security protocol.

With small businesses increasingly becoming targets of cyber-attacks, it is extremely important for owners to stay abreast of the latest developments in digital security.

On the official Varonis blog, Senior Director of Inbound Marketing Rob Sobers writes, “The proliferation of high-profile hacks in the news cycle often tricks small- and medium-sized businesses into thinking that they won’t be targets of attack.”

But this may not be the case, Sobers warns. Staying in the know makes it much harder for you to fall victim to the relentless attacks by cybercriminals.

Sobers ads, “If you or your employees believe any of the myths below, you could be opening up your business to unknown risk.”

strong-passwords-myth

The number one myth listed on the new infographic? ‘A strong password is enough to keep your business safe’. Although a strong password is important — and certainly better than ‘Admin1234′ — you need to do more.

Having a two-factor authentication and data monitoring adds another level of protection. And adding this layer of protection is in many cases enough to drive the average hacker to look for easier targets.

small-businesses-hacked-myth

Another myth listed on the infographic? “Small and medium-size businesses aren’t targeted by hackers. This is obviously false because hackers are opportunists who will target anyone as long as they can benefit from it. And small businesses are not excluded from this.

The 2018 Verizon Data Breach Investigations Report has revealed 58 percent of data breach victims are small businesses, so the idea the size of your business might exclude you is definitely a myth.

Cybercriminals hack computer systems for a variety of reasons. Once they breach your security, they could use it to launch a DDoS attack, use your IP address for other nefarious purposes and more.

industries-vulnerable-hacking-myth

Much like some businesses believe they won’t be attacked because of their size, other businesses wrongly assume that they won’t be attacked because of the industry they’re in. This myth also goes hand-in-hand with the belief that some companies don’t have anything “worth” stealing. The reality is that any sensitive data, from credit card numbers to addresses and personal information, can make a business a target.

What’s more, even if the data being targeted doesn’t have resale value on the dark web, it may be imperative for the business to function. Ransomware, for example, can render data unusable unless you pay for a decryption key. This can make attacks very profitable for cybercriminals, even if the data is deemed “low value.”

anti-virus-myth

Anti-virus software is certainly an important part of keeping your organization safe — but it won’t protect you from everything. The software is just the beginning of a comprehensive cybersecurity plan. To truly protect your organization, you need a total solution that encompasses everything from employee training to insider threat detection and disaster protection.

insider-vs-outsider-threats

While outsider threats are certainly a concern and should be monitored extensively, insider threats are just as dangerous and should be watched just as closely. In fact, research suggests that insider threats can account for up to 75 percent of data breaches.

These threats can come from anyone on the inside, from disgruntled employees looking for professional revenge to content employees without proper cybersecurity training, so it’s important to have a system in place to deter and monitor insider threats.

IT-cybersecurity-responsibility

While IT has a big responsibility when it comes to implementing and reviewing policies to keep companies cyber safe, true cybersecurity preparedness falls on the shoulders of every employee, not just those within the information technology department.

For example, according to Verizon, 49 percent of malware is installed over email. If your employees aren’t trained on cybersecurity best practices, like how to spot phishing scams and avoid unsafe links, they could be opening up your company to potential threats.

public-wifi-password-myth

If your business has employees who travel often, work remotely or use shared workspaces, they may incorrectly assume that a password keeps a Wi-Fi network safe. In reality, Wi-Fi passwords primarily limit the number of users per network; other users using the same password can potentially view the sensitive data that’s being transmitted. These employees should invest in VPNs to keep their data more secure.

computer-infected-myth

A decade or so ago it may have been true that you could tell immediately if your computer was infected with a virus — tell-tale signs included pop-up ads, slow-to-load browsers and, in extreme cases, full-on system crashes.

However, today’s modern malware is much more stealthy and hard to detect. Depending on the strain your computer or network is infected with, it’s quite possible that your compromised machine will continue running smoothly, allowing the virus to do damage for some time before detection.

BYOD-security-myth

Employees often assume that their personal devices are immune to the security protocols the company’s computers are subjected to. As such, Bring Your Own Device (BYOD) policies have opened up companies to the cyber risk they may not be aware of. Employees who use their personal devices for work-related activities need to follow the same protocols put in place on all of the network’s computers.

These rules aren’t limited to cell phones and laptops. BYOD policies should cover all devices that access the internet, including wearables and any IoT devices.

cybersecurity-preparedness-myth

Cybersecurity is an ongoing battle, not a task to be checked off and forgotten about. New malware and attack methods consistently put your system and data at risk. To truly keep yourself cyber safe, you have to continuously monitor your systems, conduct internal audits, and review, test, and evaluate contingency plans.

Keeping a business cyber safe is a continuous effort and one that requires every employee’s participation. If anyone at your company has fallen victim to one of the myths above, it may be time to rethink your cybersecurity training and audit your company to assess your risk.

2012 Norton Cyber Crime Report

2012 Norton Cyber Crime Report, a worrying scenario:

This report covers different technologies including social networking and mobile reporting the impact on final customers in economic terms.

The report involved 13018 participants across 24 countries aged 18-64 and a pool of expert collaborators.

The impact of cybercrime is worrying with 556 million of victims per year, 2 on 3 adults have been victims of on line illegals in their lifetime and the total economic loss is 110 Billion with an average cost per victim of $197.

The Asian region is the most affected by cybercrime, the global price tag of consumer cyber crime for China amounts to 46 Billion, followed by US with 21 Billion and European Area with 16 Billion.

The highest numbers of cyber crime victims were found in Russia (92 percent), China (84 percent) and South Africa (80 percent).

The technologies that have suffered the major increase in cybercrime are social networking and mobile.

It has been registered an increase in cybercrime which takes advantage of social networks and mobile technology. Mobile users are very vulnerable to attacks, 2/2 adults use a mobile device to access the internet and the mobile vulnerabilities doubled in 2011 respect previous year.

44% of users aren’t aware of the existence of solutions for mobile environments, and 35 of adults have lost their mobile device or had it stolen.

Of particular concern is an improper use of social networks, wrong management of sessions, absence of validation of visited links and a total ignorance of any security setting expose users to fraudulent activities.

15 percent of users have had their account infiltrated, and 1 in 10 have been victims of fake links or scams.

Other behaviour extremely worrying is the way in which people use public networks and operate on it, for example accessing to private services such as email.

The email accounts are one of the most appetible targets for cybercriminals because they represent a simple way to access to sensible information.

“When using public connections, 67 percent access email, and 63 percent use social networking and 24 percent access their bank account, according to the report.”

40% people don’t use complex passwords or change their passwords regularly.

Computer Virus

Computer Virus:  Like most people, you run a Windows-based operating system (or perhaps something else), you run anti-virus software. Perhaps you’re even diligent about keeping your virus definitions up-to-date. Are you completely protected against viruses?  Of course not. Let’s examine what viruses and Trojans are, and how they find their way onto your computer. We all have heard the terms Virus, Worms, Trojans and spyware but only a few of us know the difference between them. We generally consider everything that is detected by an antivirus as virus but this is not the case. All these can be harmful to your computer hardware and software. To differentiate all these terms from each other. let’s start with the introduction to viruses.

Virus: A virus is a self-replicating program that attaches itself to an executable file. When  the file is executed the virus automatically gets executed and enters into the system memory .Once it enters into the system memory it either searches for other files that can be infected or stays in the background and infects the files that  uses the virus infected program.

Worms: Worms are very similar to viruses but differ in way that they do not bind themselves to executable files instead they uses the network to replicate themselves. If you find excessive use of your network bandwidth then you may be infected by a worm. So, a worm does not require a user to execute any file for its execution it can work without user intervention.

Trojan horse: A Trojan horse is harmful program which may seem harmless to the user before its installation but instead it is programmed or reverse engineered to facilitate unauthorised remote access to the computer. Trojan’s do not replicate themselves.

  The name Trojan horse comes from that fateful episode in the novel The IliadThe limitation of Trojans is that the user needs to be convinced to accept/run them, just as the Trojans had to first accept the Greek gift of the wooden horse, in order for them to have their way. So they are typically mislabeled, or disguised as something else, to  fool the user into running them.

Spyware: A spyware is a program that secretly monitors and collects pieces of information. It usually runs in stealth mode and cannot be detected easily. Key loggers is a great example of spyware software. It is not limited to just spying but can also send data to remote computers.

Rootkit:  A rootkit is a collection of tools (programs) that enable administrator-level access to a computer or computer network. Typically, a cracker installs a rootkit on a computer after first obtaining user-level access, either by exploiting a known vulnerability or by cracking a password. Once the rootkit is installed, it allows the attacker to mask intrusion and gain root or privileged access to the computer and, possibly, other machines on the network.

A rootkit may consist of spyware and other programs that: monitor traffic and keystrokes; create a “backdoor” into the system for the hacker’s use; alter log files; attack other machines on the network; and alter existing system tools to escape detection.

If a rootkit is detected, however, the only sure way to get rid of it is to completely erase the computer’s hard drive and reinstall the operating system.

Botnets: Once users’ computers are infected with viruses, the computers are turned into “zombies”. These computers, serving as “Bots” controlled by hackers, are used to send a large number of forged data packets or junk data packets to the pre-defined target for launching a DOS (Denial-of-service ) attack. As a result, the attacked target breaks down.

 Grayware: The spyware and rogue software are software designed by certain immoral companies to collect users’ habits in browsing Web pages for working out their advertisement push policies. The grayware does not harm computers greatly. The privacy of victims, however, is compromised and collected by others. Once being installed, the gray-ware cannot be deleted or uninstalled normally. For example, advertisement software designed for the Internet Explorer can change and lock default homepages automatically, and load the toolbars of advertisement companies.

 Malware: Malware is mischief. Malware is not infectious, but can also lead to serious consequences. For example, when certain malware is run, hard disks are formatted automatically, which causes the great losses of users’ important data.

 Features of Computer Viruses:

  • Destructive  

               When a computer is infected with viruses, normal programs cannot be run, and important data may be damaged or stolen. Thus, huge losses are caused.

  • Infectious

                     Computer viruses are destructive as well as infectious. The infectivity is more harmful. Once viruses are reproduced or virus variations are generated, the spread speed is rather fast. The viruses are hard to be defended. Viruses can spread through multiple means such as storage media and networks. Among them, the network becomes a major means of virus spread.

  • Covered

                   Computer viruses are well-covered. For common users, computer viruses are difficult to sense.

  • Latent

                   Certain viruses have “latent periods”. These viruses burst out sometime in the future. For example, in 1999, CIH viruses damaged the BIOS. The CIH viruses burst out on April 26 every year. If latent periods of viruses are long, viruses can exist in systems for a long time. Thus, the infectious scale of viruses is large.

Basically, viruses are programs that the programmer designed to do something you generally would not want to have happen if you were aware of their function. These programs usually get onto your computer through some sort of trickery. They pretend to be something else, they’re attached to a program you wanted, or they arrive on media you inserted without knowing it was infected. They can also be placed by a remote attacker who has already compromised your security.

How does anti-virus software work? Before program execution can take place, the anti-virus software will scan the program or media for “bad things,” which usually consist of viruses, Trojans, and even a few potential hacker tools.

               Keep in mind, though, that your anti-virus software vendor is the sole determiner of what to check for, unless you take the time to develop your own signature files. Signature files are the meat of most anti-virus programs. They usually consist of pieces of code or binary data that are (you hope) unique to a particular virus or Trojan. Therefore, if you get a virus that does not appear in the database, your anti-virus software cannot help you.

             So why is the process so slow? In order to produce a signature file, an antivirus vendor has to get a copy of the virus or Trojan, analyse it, produce a signature, update the signature file (and sometimes the anti-virus program too) and publish the update. Finally, the end user has to retrieve and apply the update. As you might imagine, there can be some significant delays in getting new virus information to end users, and until they get it they are vulnerable. You cannot blindly run any program or download any attachment simply because you run anti-virus software. Not so long ago, anti-virus software could usually be relied upon, because viruses propagated so slowly, relying on people to move them about via diskettes or shared programs. Now, since so many computers connect to the Internet, that connectivity has become a very attractive carrier for viruses. They spread via Web pages, e-mail and downloads. Chances are much greater now that you will see a new virus before your anti-virus software vendor does. And don’t forget that a custom virus or Trojan may be written specifically to target you at any time. Under those circumstances, your anti-virus software will never save you.

Steps to remove virus from computers: 

    1. If the computer is on then restart. Keep tapping F8 and start the computer simultaneously and select “safe mode with networking” from the Advanced Boot Menu by using the arrow keys and press the “Enter” key on the keyboard.

Note: The reason we go to safe mode is because, most viruses do not function in safe mode.   

                 

2. Delete Temp (temporary) files.

For Windows XP – Click on “start” button from the desktop and select “Run”. In the run text box type “%temp%” and press “Enter”.

For Windows Vista and Windows 7 – Click on “Windows logo” and on the search box just above the Windows logo, type “%temp%” and press “Enter”.

Now the “Temp” folder will open. Select all the files and press Shift + Delete to delete the files.

3. Delete prefetch files.

For Windows XP – Click on “start” button from the desktop and select “Run”. In the run text box type “prefetch” and press “Enter”.

For Windows Vista and Windows 7 – Click on “Windows logo” and on the search box just above the Windows logo, type “prefetch” and press “Enter”.

Now the “Prefetch” folder will open. Select all the files and press Shift + Delete to delete the files.

4. In Windows XP , MS Removal Tool is running or keeps popping up, look for them in the task manager and close it. Also, you can disable them in services. To access services follow the steps below:

For Windows XP – Click on “start” button from the desktop and select “Run”. In the run text box type “services.msc” and press “Enter”.

For Windows Vista and Windows 7 – Click on “Windows logo” and on the search box just above the Windows logo, type “services.msc” and press “Enter”.

5. Download the free version of Malwarebytes and run a virus scan. Following the scan if there is any infection it will show and give you the option to delete . After you remove the virus, it may ask you to restart.

6. If Malwarebytes does not help, then try Hitman pro. Before downloading check whether the system is 32 bit or 64 bit as Hitman Pro has different version for 32 bit and 64 bit.

7. Try TDS Killer from Kaspersky. Download TDS Killer.exe file and run a scan for Rootkits.

8. Try Combofix. It is a freeware but  very good software to remove virus. It is available for free download. While you run Combofix you may lose Internet connection temporarily.

9. You may also try SuperAntispyware. You may try this only when none of the other software given here helped.

10. If you are unable to run or access the computer even in safe mode then create a new user account and login to that. Now start running the software. If they do not detect anything, go to the user account which is affected and look for suspicious files. Confirm with the user, if they are aware of such file, if not, delete it. Then try going to the affected user account and run the anti virus software.

11. If after virus removal, you face issues with file association or running .exe files on Windows XP, then try the tweaks from Kellys Korner XP.

12. If nothing works and severe damage is done. Then we have two options left:

  • If there is important data on the computer then you should take the hard disk to a local vendor to check if the data can be backed up. Then perform a clean installation of operating system. That is, you should format your hard drive and install your Windows OS again.
  • If there is no important data, then you can go ahead and do a clean installation of Windows OS.

World Computer Security Day

Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users  from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.

Protect your hardware:
Safety and security start with protecting computers. Install a security suite (antivirus, antispyware, and firewall) that is set to update automatically. Keep your operating system, Web browser, and other software current as well and back up computer files on a regular basis.

Use strong passwords:
Make sure that your password is long, complex and combines, letters, numerals, and symbols. Ideally, you should use a different password for every online account you have. If you need to write down your password to remember it, store it somewhere away from your computer.

Email:
Before opening any email attachments, be sure you know the source of the attachment. It is not enough that the mail originated from an address you recognize. The Melissa virus spread precisely because it originated from a familiar address. Malicious code might be distributed in amusing or enticing programs.

Keep personal info personal:
Be cautious about how much personal information you provide on social networking sites. The more information you post, the easier it may be for a hacker or someone else to use that information to steal your identity, access your data, or commit other crimes such as stalking.
