Important Steps to Take Before You Recycle a Mobile Phone Number 

It’s not unusual to change a mobile number from time to time. For example, when you move, you may want a number that is local to the area you just moved to. Companies also may end up recycling mobile numbers throughout their staff as people come and go.

If you don’t properly detach your mobile phone number from all the accounts it’s used with, you can leave yourself open to identity theft, credit card fraud, and other crimes.

In a 2021 Princeton University study, it was found that 66% of mobile numbers listed as available by major mobile service providers were still connected to accounts on popular sites (Amazon, PayPal, etc.). 

So, after the former owners had turned in the number, it was available for someone else to use when signing up for mobile service. And that number was still being used on the former owner’s cloud accounts, allowing those accounts to easily be breached.

Because our mobile numbers are connected to much of our online and offline life, it’s important to take certain steps to ensure that you don’t leave yourself at risk when recycling your phone number.

Change Your Phone Number for Online Accounts

We all generally have more online accounts than we immediately remember. The average person must juggle 100 passwords, and most of those passwords will be to a website or cloud app service of some kind.

The first thing you want to do is begin visiting your online accounts and cloud applications to update your mobile phone number. Many of these apps now use a text message to your number as a form of verification if you’ve lost your password.

You want to ensure any password reset messages go to you and not someone that has requested your old number for the express purpose of identity theft or account compromise.

Change Your Number for Social Media Accounts

Technically, a social media account is also an online account, but many people think of them as a separate entity. When a Facebook or LinkedIn account is compromised, the hacker often will send social phishing messages out to your friend connections to try to gain access to sensitive data or scam them out of money.

Make sure to change the phone number listed in your social media accounts. If you are using WhatsApp, which is tied directly to your mobile number, make sure to follow their instructions on changing your number so your communications will remain secure.

Change Your Phone Number for Service Providers That Send You Texts

Text messaging is beginning to replace email for many types of communications. This includes things like shipping notices, confirmations of payments from utility companies, appointment reminders, and sale notices from retailers.

This puts you more at risk if you change your mobile number because the texts you receive from various service providers can be used for identity theft.

Make sure to connect with any services you use that contact you by calling or texting your mobile number to update your information. These offline services could be a:

• Plumbing or HVAC company
• Dentist or doctor’s office
• Pharmacy
• Local retailer
• Utility company

Double Check All Your Multi-Factor Authentication Prompts

One of the big dangers of having a stranger able to receive your text messages is that they could have access to your codes for multi-factor authentication (MFA).

MFA is designed as a safeguard to help prevent an account breach, even if the perpetrator has your username and password. But if the criminal gets the MFA codes sent to your old number, they can easily get in and change your password, locking you out of your own account.

As you go through the process to update your mobile number in your online accounts, double-check the MFA prompt for any that use this form of authentication security. You want to make sure it’s been properly changed to send a message to your new number.

Review Your Text Message History for Anything You’ve Missed

Inevitably, there will be online accounts or service providers that you’ve missed. For example, that place you always order flowers for on a loved one’s birthday every year but never visit at other times.

Scroll through your text message history to find any other accounts that you may have forgotten to update.

Text Friends, Family & Colleagues from the New Number

Once your online security is taken care of, you want to stop friends, family, and colleagues from accidentally texting your old number. This can happen in both one-on-one and group SMS chats.

Send a text message from your new number asking them to immediately update your contact with that number when they receive it. Then go the additional step by asking them to delete any messages that used your old phone number. This can help prevent them from accidentally grabbing that message instead of your new one when texting you in the future.

How Secure Is Your Mobile Device?

Mobile devices are increasingly being attacked by malware and phishing. Is your device properly secured? Don’t leave yourself at risk, request a mobile security check to protect your personal data and identity.

Top 5 Cybersecurity Mistakes That Leave Your Data at Risk

The global damage of cybercrime has risen to an average of $11 million USD per minute, which is a cost of $190,000 each second.

60% of small and mid-sized companies that have a data breach end up closing their doors within six months because they can’t afford the costs. The costs of falling victim to a cyberattack can include loss of business, downtime/productivity losses, reparation costs for customers that have had data stolen, and more.

You may think that this means investing more in cybersecurity, and it is true that you need to have appropriate IT security safeguards in place (anti-malware, firewall, etc.). However, many of the most damaging breaches are due to common cybersecurity mistakes that companies and their employees make.

The 2021 Sophos Threat Report, which looked at thousands of global data breaches, found that what it termed “everyday threats” were some of the most dangerous. The report stated, “A lack of attention to one or more aspects of basic security hygiene has been found to be at the root cause of many of the most damaging attacks we’ve investigated.”

Is your company making a dangerous cybersecurity mistake that is leaving you at high risk for a data breach, cloud account takeover, or ransomware infection?

Here are several of the most common missteps when it comes to basic IT security best practices.

Not Implementing Muti-Factor Authentication (MFA)

Credential theft has become the top cause of data breaches around the world, according to IBM Security. With most company processes and data now being cloud-based, login credentials hold the key to multiple types of attacks on company networks.

Not protecting your user logins with multi-factor authentication is a common mistake and one that leaves companies at a much higher risk of falling victim to a breach.

MFA reduces fraudulent sign-in attempts by a staggering 99.9%.

Ignoring the Use of Shadow IT

Shadow IT is the use of cloud applications by employees for business data that haven’t been approved and may not even be known about by a company.

Shadow IT use leaves companies at risk for several reasons:

• Data may be used in a non-secure application
• Data isn’t included in company backup strategies
• If the employee leaves, the data could be lost
• The app being used might not meet company compliance requirements

Employees often begin using apps on their own because they’re trying to fill a gap in their workflow and are unaware of the risks involved with using an app that hasn’t been vetted by their company’s IT team.

It’s important to have cloud use policies in place that spell out for employees the applications that can and cannot be used for work.

Thinking You’re Fine With Only an Antivirus Application

No matter how small your business is, a simple antivirus application is not enough to keep you protected. In fact, many of today’s threats don’t use a malicious file at all.

Phishing emails will contain commands sent to legitimate PC systems that aren’t flagged as a virus or malware. Phishing also overwhelmingly uses links these days rather than file attachments to send users to malicious sites. Those links won’t get caught by simple antivirus solutions.

You need to have a multi-layered strategy in place that includes things like:

• Next-gen anti-malware (uses AI and machine learning)
• Next-gen firewall
• Email filtering
• DNS filtering
• Automated application and cloud security policies
• Cloud access monitoring

Not Having Device Management In Place

A majority of companies around the world have had employees working remotely from home since the pandemic, and they’re planning to keep it that way. However, device management for those remote employee devices as well as smartphones used for business hasn’t always been put in place.

If you’re not managing security or data access for all the endpoints (company and employee-owned) in your business, you’re at a higher risk of a data breach.

If you don’t have one already, it’s time to put a device management application in place, like Intune in Microsoft 365.

Not Providing Adequate Training to Employees

An astonishing 95% of cybersecurity breaches are caused by human error. Too many companies don’t take the time to continually train their employees, and thus users haven’t developed the skills needed for a culture of good cybersecurity.

Employee IT security awareness training should be done throughout the year, not just annually or during an onboarding process. The more you keep IT security front and center, the better equipped your team will be to identify phishing attacks and follow proper data handling procedures.

Some ways to infuse cybersecurity training into your company culture include:

• Short training videos
• IT security posters
• Webinars
• Team training sessions
• Cybersecurity tips in company newsletters

When Did You Last Have a Cybersecurity Checkup?

Don’t stay in the dark about your IT security vulnerabilities. Schedule a cybersecurity audit to uncover vulnerabilities so they can be fortified to reduce your risk.

Making Your VoIP Network Bulletproof (Six Tips to Protect Your VoIP from Cyberattacks)

Hardly any phone call system in a business beats VoIP when it comes to efficiency and flexibility. However, it’s not immune to cyberattacks. Discover how you can secure your VoIP ASAP.

What kind of communication system are you using for your business?

I asked because many modern-day businesses have now switched to the Voice Over Internet Protocol (VoIP). This technology allows employees to perform voice calls using only their internet connection. 

It’s often a wise choice considering that using VoIP comes with several benefits to a business.

Among its benefits include lower operating costs, greater convenience than traditional services, increased accessibility, higher scalability, and the ability to multitask. VoIP also comes with advanced features for teams of all sizes, is completely portable, and offers superior voice quality. 

However, VoIP systems also have limitations, with cyberattacks being their number one downside. 

The good news is that it’s possible to protect a business’s VoIP system from hackers. And if you already implemented this in your business, it’s not too late to secure it.

Read on to discover the most common threats to your network and tips on preventing them.

The Need for VoIP Protection

All VoIP systems require a stable internet connection to function properly. Unfortunately, their reliability on the internet makes them vulnerable to various security issues.

Some of the most frequent ones include:

Security Issue #1. Denial of Service

Denial of Service (DoS) is a common threat to VoIP systems comprising attacks designed to shut down a machine or network and make it inaccessible for use. 

When this happens, legitimate users of VoIP technology may not be able to access their information systems and devices. And call centers can be affected by lower call quality, uptime, and latency. 

Security Issue #2. War Dialling

War dialing is an attack that controls the company’s private branch exchange (PBX) and scans for other phone networks. This means hackers can dial numbers and connect to modems and other extensions.

Security Issue #3. Toll Fraud

Toll fraud is a threat that consists of making calls to outside lines from a company’s existing system. 

For example, hackers will dial costly international numbers intending to rack up toll charges to your business. 

Security Issue #4. Phishing

This is a common threat wherein attackers send fraudulent messages designed to trick victims into revealing sensitive information. Often, the unsuspecting victims would divulge information about passwords, internal IP networks, and similar data. 

Security Issue #5. Malware

It’s a threat where attackers install malicious software via email or phone. A file or code gets delivered over a network and has the goal of infecting, stealing, or exploring the information contained within a system. 

After infecting the system with malware, VoIP hackers can enter your network and access critical business information. 

Security Issue #6. Call Interception

The call interception attacker uses unsecured networks to intercept the Session Initiation Protocol (SIP) traffic that serves to initiate, maintain, and terminate real-time voice and video sessions. 

A victim of a call interception attack can be redirected to another line hosted by the hacker, for example.

6 Tips for Boosting VoIP Security

Given the variety of threats imposed by attackers on VoIP systems, it’s necessary to optimize your VoIP security ASAP. 

Here are 6 valuable tips to get you started.

Tip #1. Set Up a Firewall 

Secure firewalls are necessary for all VoIP systems. It’s important to make your VoIP software and hardware firewalls scan information that goes in and out of the system and ensure it’s secure. 

If spam or a threat comes your way, the firewall will identify and gain control over it, shielding your system shielded from the attack.

Also, a good firewall will allow the data packets you send to travel unhindered. 

Tip #2. Use Strong Passwords 

Your VoIP system is no different from any other software or platform you use for handling sensitive information. For this reason, it needs to be protected with strong and regularly updated passwords. 

Aim for combinations of at least 12 characters, including numbers, upper- and lower-case letters, and special symbols. And for ultimate protection, go for passwords consisting of a random character series. 

It’s crucial to set a password as soon as you configure your VoIP system. Otherwise, you’re likely to forget about it later. 

Also, remember that some VoIP phones come with pre-set passwords, often available publicly. That’s why you should change yours as soon as you get a chance. 

Ideally, try to change your passwords every three months.

Tip #3. Restrict Calling

Many VoIP attacks happen due to toll fraud. So, if your business runs locally, there’s no need to have the international call option enabled. This allows you to be on the safe side and avoid paying expensive bills you weren’t even responsible for making. 

You can let your VoIP service block 1-900 numbers to avoid toll fraud. 

Tip #4. Encourage Your Team to Report Suspicious Behaviour 

Many of the VoIP attacks arrive due to irresponsible behavior. To prevent this from happening, educate your team on how they can best do their job without affecting the system’s security. 

For starters, they should know how to spot unusual network activity, handle passwords, and report suspicious behavior. They should also report ghost calls and missing voicemails whenever received. Staff also shouldn’t store voicemail for too long. 

The reality is that sometimes, cybersecurity training during onboarding often isn’t enough. That’s why you should do periodical training to keep your VoIP safe at all times. 

Tip #5. Deactivate Web Interface Use 

Ideally, you should deactivate the web interface used for your VoIP system. 

Why?

Using phones on a desktop computer opens an area of weakness to attackers. It’s enough for a single phone user falling prey to leave the whole system exposed to an external party. All your data can be stolen in text format as a result. 

So, unless it’s absolutely necessary for you to use the web interface, be sure to secure it very strictly.

Tip #6. Use a VPN for Remote Workers

Virtual Private Networks (VPNs) are great software that encrypts traffic regardless of your employee’s location. 

You can set up such a network for your remote staff to prevent data leaks and breaches. The good news is that using this service won’t degrade the call quality. 

(Re)Gaining Control Over Your VoIP Security

VoIP systems are a fantastic alternative to landlines. After all, they offer many more features and flexibility at a fraction of the cost. However, their reliability on the internet also makes them susceptible to cyberattacks. 

If you have just set up a VoIP system for your company or are thinking of starting one, securing it should be your number one priority. Don’t risk falling prey to toll fraud, malware, phishing, and other attacks. Take some time to secure your business by following the tips from this article. 

And if you need more help to implement these changes or would like to further discuss securing your business’s VoIP system, reach out to us and we can set up a 10-15-minute chat.
