Vulnerability

Why It’s Important To Change Your Router’s Default Log-in

October 25, 2016

Mike Simonelli is a network technician for Tech Experts.

It’s a pretty common scenario: a small business wishes to add Wi-Fi to its existing network infrastructure. A quick trip to the nearest big-box store reveals several Wi-Fi capable routers or access points to choose from. Grabbing up the mid-priced model, the business owner heads back to the shop and uses the included Ethernet cable to plug the new device into an existing switch and, just like that, instant Wi-Fi.

There are a couple of concerns regarding the above scenario that the savvy business owner should be having. The first and most obvious: “I plugged it in and now everyone with a laptop has unrestricted access to my network.” How do you control who can connect to your Wi-Fi?

The answer is to enable a wireless security protocol on the router or access point. WEP is an acronym for Wired Equivalent Privacy (or Wireless Encryption Protocol) and it was designed to provide the same level of security as that of a hard-wired Ethernet connection.

Because wireless networks broadcast messages using radio waves, they are subject to eavesdropping. WEP provides security by encrypting the data to protect it as it is transmitted from one point to another. Almost all wireless devices will support WEP and instructions for enabling it on a particular device should be readily found in the documentation.

Enabling WEP will keep people without the correct password off your Wi-Fi and also prevent unauthorized eavesdropping of network traffic.

Another often overlooked concern is changing the default credentials that are needed to login and administer the new wireless device.

I can’t tell you how many times that I’ve connected to a wireless network and browsed to the default gateway I was assigned (normally something like http://192.168.0.1) and typed in “admin” and “password” on the login form that is presented and gained access to the router’s configuration.

The username “Admin” and the password “password” are typically the default credentials as they come pre-configured on Linksys routers, as well as some other brands.

If these credentials work, then potentially anyone can have unrestricted access to your router’s configuration. At this point, no wireless security protocol such as WEP will protect you since it can simply be turned off in the router’s administration interface.

Worse yet, an intruder can set his/her own password and change the admin password to something else. Once this happens, usually the only way to regain access to your own Wi-Fi network is to factory reset the device, which removes all of your configurations.

The bottom line – never leave a wireless device at its default settings when you connect it to your network. By taking the time to follow these simple guidelines, you will make your wireless device a worthwhile addition to your infrastructure, as well as making your network that much more secure.

Anti-Virus Advice For Your Small Business

August 15, 2016

Brian Bronikowski is a field service technician for Tech Experts.

Anti-virus has always been a major concern for users at all levels. From trojans and keylogging programs, to ransomware and malicious software, there is always a new threat on the table.

When we purchase an anti-virus software, there is a certain feeling of security we expect to have, that there is no worry when it comes to those malicious attacks. That’s what the money goes towards. The problem is that sometimes anti-virus actually does quite the opposite.

In a recent study, household name Symantec (Norton) was labelled with multiple critical vulnerabilities that in fact make the system less secure than if it was running without an anti-virus program.

One would hope that a company of this size would be able to resolve these before they’re discovered — or at the very least, promptly look for ways to clean up their act. Unfortunately, Symantec wanted to put on the brakes and wait before patching these flaws that affect every product associated with the company.

Most of the affected systems have been patched since the first reports from June. When you see a report like this and pair it with the performance-degrading effects large anti-virus companies impose, it becomes a simple question: what do you do?

There are a multitude of protection software on the Internet and in-store. Some of these will go back and forth in terms of highest rankings. Some are big brands that are pre-installed on most computers. Others are less well known, but gaining ground. It’s all about finding the right one for you.

More often than not, we will see the likes of McAfee and Norton on systems. These are loaded for you when you buy a new system and will start as a trial. Users will often purchase the system instead of going through the arduous task of properly removing an anti-virus program.

The problem here is that generally the user will purchase whatever is “recommended” which will often be an entire security suite. These will bring a low-end computer to a halt and greatly degrade the mid-range and higher end computers.

It is important to stay away from the big names like these as there is little innovation and plenty of flaws. Some of these flaws may be performance alone and others are security flaws.

Some of the lesser known programs are often times a good alternative. With these, it’s always good to look at any recent vulnerabilities or complaints users have had.

Some protection systems have deleted files or overwritten system files in the past. Research is important for these situations. That said, common free programs, such as AVG and Avast, are found on millions of systems.

Keep in mind, most free protection softwares have one catch or another. Spam-like interfaces that constantly ask for purchase or the requirement for manual scanning are the most common culprits. If you are able to stay on top of things, these can work out well enough.

Unfortunately, most users are unable to due to the workload given to them. Protection ends up being an afterthought; one that can cost a lot more than the software itself. There is one nearly foolproof way to get rid of these worries for good: allowing professionals to take care of your protection.

Tech Experts is able to supply a managed anti-virus that is inexpensive, well-reviewed, and kept up-to-date with the latest virus definitions. We are able to install it in both home and business environments.

With that in mind, it’s an easy choice when picking what you want to shield you from the dangers of the digital world.

How An End User Might Accidentally Undermine Your Security

July 28, 2016

Michael Menor is Vice President of Support Services for Tech Experts.

If you’re like every other small business out there, you know that the more employees you hire, the more technology that you have to procure. However, when you have more end-users, you provide more avenues for threats to slip into your network infrastructure unnoticed.

When all it takes is one simple mistake from a single end-user, how can you minimize the chances of falling victim to an untimely hacking attack? We’ve put together a list of honest mistakes that any end-user can make – and how they can be prevented.

Clicking on malicious links
With so much information on the Internet, it’s easy for an employee to search through countless pages without any regard to the sites and links that they’re clicking on.

You need to emphasize the importance of safe browsing, including double-checking the destination of a link before clicking on it. You can do so by hovering over the link and looking in the bottom-left corner of your browser.

Using weak passwords
Employees frequently use passwords that aren’t strong enough to keep hackers out. Often times, they’ll simply use something of personal significance, like the name of their pet or a specific date.

This isn’t the right way to approach password security. Instead, users should attempt to put together passwords that are private, randomized strings of numbers, letters, and symbols.

Losing unencrypted devices
It’s not unheard of for an employee to use company devices in public places. If they accidentally leave their smartphone on the bus or their tablet on a park bench, there’s always the risk that it can be stolen.

Unless you practice proper encryption protocol, any information available on the device can be accessed by the person who finds it, be it a good Samaritan or a tech-savvy thief.

Implementing unapproved solutions
Some employees simply prefer to use solutions that aren’t provided by the company to get their work done. The problem here is that the employee is moving forward without consulting IT about it and that your data is being used in a solution that you can’t control.

Plus, if the employee is using free or open-source software, these often come bundled with unwanted malware that can put your data in even greater peril.

Personal email use
It’s one thing to check your personal email account while at work, but another entirely to use your personal email account to perform work purposes.

As the recent debacle with Hillary Clinton shows, people don’t take kindly to sensitive information being leaked via an unsecured email server that their organization has no control over.

Add in the fact that personal email accounts are often not as secure as those in a professional productivity suite and you have a recipe for disaster. You need to reinforce that your team should keep their work and personal email separate.

Leaving workstations unattended
Besides the fact that some tech-savvy employees are practical jokers, it’s a security risk to leave a workstation unlocked and unattended for long periods of time.

Imagine if someone from outside of your organization walked into your office and accessed confidential files without authorization; that’s on the employee who got up and left the device unattended.

Encourage your employees to always log off of their workstations, or at least lock them, before stepping away from it. User error is a primary cause for concern among businesses, but it can be mostly avoided by providing your staff with the proper training.

Ransoming Your Business One Step At A Time

May 26, 2016

When it comes to business security, today’s climate is a careful one. It seems like every week the latest and most dangerous ransomware is coming for us.

These can come through a variety of ways, like employees, clients, and websites. The most recent threat we’ve seen is called Rokku. Built upon predecessors, it’s only the next step in the fight against business security systems. Ransomware is a dangerous thing. The main concept is a mix of fear tactics and file encryption. After the system is infected, the virus will normally lay dormant for a time.

Once every file is found and changed to an encrypted state, a message will display, stating the worst.

All of your files are locked until you pay whatever sum the developers demand. Once in this state, you are generally given only a number of hours before your files and content are deleted permanently.

In this instant, many people will jump up to pay for their files in order to save further expense and headache. Unfortunately, doing so rarely helps the issue.

After the ransom is paid, you are supposedly granted access to the files and everything continues on unhindered. That said, there are many times you can send the money in and receive nothing in return.

Your files will still have their encrypted extensions (e.g. *filename*.rokku) and you will be in an even bigger hole than before. Some of the older encryptions have programs made by third parties to help those infected, but this is also often not the case.

In the Rokku scenario, there is no progress made in decryption. No patterns have been found and files are completely distorted in comparison to their original state.

As if it isn’t already enough, there is still more to worry about. Rokku as well as other ransomwares will not stop at only the infected computer. Network shares are also subject to complete encryption.

In short order, your entire network is no longer your own. With this in mind, the question is simple. What can you do?

Ransomware is definitely a problem and is not going away anytime soon.

That said, there is more progress these days than when we first started seeing it pop up on systems. Using Rokku as an example, some newer versions are built off of older attacks.

As such, they can often follow the same patterns and can be taken care of. Anti-virus and anti-malware services are also more and more proactive against these threats.

User error can, however, still cause alarm and ruin things very quickly. Rokku and many of its predecessors are sent through email attachments. Once opened, they will start to run and everything will spiral downward from there.

It is important to know and keep others informed on basic safety practices when it comes to operating computers. Keep in mind to not trust strange sites, emails, or messages that you were not expecting or do not know the sender. Also, be aware of common spam signs.

Misspellings, exaggerated results, and poor grammar are often giveaways.

If you want to review your current computer climate, we recommend giving us a call. With preventive maintenance, business class protection, corporate antivirus, and monitors running to ensure a steady flow, we can ensure the safety and reliability of any network and the important files that it may contain.

The absolute best way to avoid a disaster such as Rokku and other ransomwares is to stop it before it happens.

Do You Have A Blind Spot In Your Security?

May 26, 2016

Security is only as good as its weakest link — one blind spot and a company can be compromised. It is important that each aspect of a company’s security is understood and up to date.

With the following best security practices, it can be better understood what to be aware of and how to better advance a company’s security.

From remote hackers, to in-person social engineering, and even your own e-mail, there are different methods of attacks and means of defense to maintain a company’s integrity.

Physical Security
The basic defense that predates IT security is physical security. Locked doors, restricted access, and watch patrol are some of the oldest methods to prevent aggressive physical security breaches.

Technology has only made physical security even better with security cameras, alarm systems, RFID badges, and biometric systems that identify a person from their physical being. Having the appropriate physical security is key to preventing and deterring break-ins and stolen items.

Social Engineering
With the right words and story, some people gain access to compromising areas and information that can give a company a real bad time.

Without a physical break-in or even a computer, social engineering works against human psychology, finding the vulnerabilities of staff and workers to trick and deceive their way past security. The best way to defend from this is to have a strong and easily understood security policy that educates staff and workers not give out credentials and access to unauthorized personnel.

Phishing
Billions of emails are sent out every day — promising a vacation, warning people about their bank accounts, or asking for charity — that are entirely design to steal or compromise a person or company. Phishing targets everybody, asking for credit card numbers, asking a person to sign in to their account on a fake site, or taking something in other ways.

Do not open emails or download email attachments with suspicious or unknown origins. If an email looks odd or is too good to be true, call or check a website directly to confirm if an email is legitimate.

Clicking or falling for phishing could end with a stolen identity, stolen money, or a locked PC or network demanding ransom money. Be smart and wise about checking emails.

Hackers
There are people that spend most of their day trying to break security codes, finding software loop holes, and other abstract means to force their way through digital security to gain illegal access to computers.

There are just as many (if not more) people working together to prevent such people from ever gaining access with new security measures and patches. To protect a PC or a company from hackers, always update your security definitions on Windows and antivirus software. Knowing what software to trust and what updates are needed are important ensuring digital security. We at Tech Experts make it our business to keep digital security online and updated at all times, so that no one has to fall victim to the unseen security threat.

Being aware of these different security risk and knowing how to defend from them can give a strong basis in understanding and learning in what needs to be done to keep a company or person secure.

Security is always evolving and changing, but having a modern understanding with security in place can make the difference between a secure environment and a risky work place that could come to a grinding halt when security is breached. Be safe, be smart, and be productive with good security.

Ransomware Now Targeting Mac Computers

April 18, 2016

While ransomware has been around for some time, it has never appeared to pose a threat to Apple’s Mac computers. That recently changed with the first attack of its kind last month. Ransomware is a malicious software that, once downloaded, essentially locks important files on a computer and then prompts users to pay a fee to have those files unlocked. There have undoubtedly been attempts to target Mac users in this way in the past, but this incident involving KeRanger software transmitted through the peer-to-peer file sharing network BitTorrent was the first successful one.

The attack affected approximately 6500 Mac users who downloaded the malicious KeRanger software. In the scheme of things, that number is quite low. The incident, however, proves that Mac users aren’t immune to this type of threat. As John Bambeneck of Fidelis Cybersecurity notes, “It’s a small number but these things always start small and ramp up huge. There’s a lot of Mac users out there and a lot of money to be made.” In this case, Palo Alto Networks detected the ransomware quickly, which is why Apple was able to neutralize the problem.

In the future, however, ransomware attacks on Macs may become more subtle. Apple reports that it has increased its security measures and revoked the digital certificate that was responsible for launching the KeRanger software.

Severe Security Vulnerabilities Patched By Microsoft

March 8, 2016

Early last month, Microsoft released 13 security patches as part of Patch Tuesday.

While such security measures are usual, this one was particularly important because six of those patches were categorized as critical and require user attention to be put into place.

These six patches addressed programming flaws that had the potential to give cyber-attackers the means to gain full user rights in a wide array of Microsoft’s software programs. The remaining seven patches address the elevation of privileges, denial of service, and ways to bypass security features.

The programs that were at risk from these flaws included all supported versions of Microsoft Windows, the new Edge browser, Internet Explorer, Microsoft Office (including Services and Web Apps), Microsoft Server Software, Adobe Flash Player, and Microsoft .NET Framework.

According to Microsoft, these flaws were detected before any actual security breaches stemming from these issues actually occurred.

If they had not been discovered, cybercriminals may have been able to gain user rights to Microsoft programs via specially crafted websites from remote locations.

Microsoft strongly urges Windows Vista and later operating system users to ensure the latest updates have been installed, especially if they do not have their systems set for Automatic Updates.

Five Things Small Business Owners Need To Know About Identity Theft

November 24, 2015

Thomas Fox is president of Tech Experts, southeast Michigan’s leading small business computer support company.

We often hear about issues with personal identity theft, and the havoc it can wreak on your credit and reputation. Less discussed, though, is small business identity theft, and how it can affect your company. Here are five things business owners need to know.

Small businesses are liable for their bank accounts
If someone steals money out of your personal account, chances are your bank is going to cover that. But if a small business account gets drained, small business owners are on their own.

Banks typically won’t cover these types of losses. Sometimes, a computer crime endorsement on your business insurance policy is available, and may cover some of your losses. With nearly all banks offering online access to account information, experts recommend you regularly monitor your accounts.

Does Your Company Need An Internet Usage Policy?

July 27, 2015

Scott Blake is a Senior Network Engineer with Tech Experts.

With the growth and expansion of the Internet, it is important to make sure that your business has a policy in place to protect its assets.

Depending on your business, an Internet Usage Policy (IUP) can be long and drawn out or short and to the point.

An IUP will provide your employees with guidelines on what is acceptable use of the Internet and company network. IUPs not only protect the company, but also the employee.

Employees are informed and aware of what is acceptable when it comes to websites and downloading files or programs from the Internet.

When employees know there will be serious consequences for breaking the IUP, such as suspension or termination of employment, companies tend to notice a decrease in security risks due to employee carelessness.

You will need to make sure your IUP covers not only company equipment and your network, but also employee-owned devices such as smart phones and tablets. You may be surprised at the number of employees that feel they do not have to follow the IUP because they are using their own device to surf or download from the Internet.

Make sure you address proper usage of company-owned mobile devices. Your business may have satellite employees or a traveling sales force. Even when they are away, they need to be aware they are still representatives of the business and must follow the business IUP.

After all, it would not go over well if your sales staff was giving a presentation to a prospective client and suddenly, “adult content” ads popped-up on the screen because one of your employees was careless in their web habits.

The downloading of files and programs is a security risk in itself. Private, internal company documents and correspondence downloaded from your company’s network can become public, causing unrepairable damage.

On the same thought, employees downloading from the Internet open your company’s network up to malware attacks and infections.

There are a lot of hackers that prey upon the absent-minded employee downloading a video or song file by hiding a piece of malware within the download. Once the malware makes it into your network, there’s no telling what damage it can cause.

As for non-work related use of the company network and Internet, make sure your employees know there is no expectation of personal privacy when using the company’s network and Internet connection.

Make it well-known that the network and Internet are in place to be used for work purposes only. Improper use of the network can reduce bandwidth throughout the company network.

This includes all mobile devices owned by the company. This way, your employees know that no matter where they are they still must follow the guidelines of the IUP.

Make sure all of your employees sign the IUP and fully understand what it is they are signing. Make sure you answer any and all questions they may have.

This will help clear up any confusion your employees may have. This way, there can be no excuses as to why the IUP was broken.

Whenever you update the IUP, make sure you have all of your employees sign and understand the new additions and/or changes to the IUP. It may seem like overkill, but you’ll be glad you did if you ever run into any violations of your company’s IUP.
