How confident are you that you can spot a fake text from your bank or a fraudulent "urgent" email from a coworker?

As digital threats become more sophisticated, the traditional advice to just "look for typos" no longer cuts it. 

Scammers now use high-quality branding and psychological triggers to bypass our natural skepticism. 

Here's a Cool Tip:  Play the "Be Scam Ready" Game from Google.

This "Be Scam Ready" game puts you in the hot seat to test your instincts against realistic, real-world scenarios.

Cut the Jargon: Why This Game Might Be the Security Game You Need to Play

The nonstop flood of cybersecurity acronyms is more than a nuisance.  It creates confusion that can weaken defenses. BeyondTrust’s new game, Acronym Overload, aims to fix that problem in a surprisingly effective way.

By Rodger Mansfield, Technology Editor

September 12, 2025

Think about the last time you sat in a security meeting. 

Someone probably said, “We need to shore up IAM, JIT, ZTNA, and ABAC” and you nodded along even though at least one of those terms was fuzzy. 

Most of us have been there. Acronyms dominate security conversations, but too many shortcuts can bury meaning. 

When clarity slips, risks grow.

Here's a Cool Tip:  Play the Acronym Overload game.

BeyondTrust has built a short browser game called Acronym Overload to bring the problem into focus. 

It feels playful, but the purpose is serious: to keep your team speaking the same language when it matters most.

What You'll Gain

• Securely lend your computer to others.
• Protect your personal data from prying eyes.

Urgent Chrome Security Alert: Update NOW to Patch Zero-Day Exploit (CVE-2024-4671)

Urgent Chrome Security Alert: Update NOW to Patch Zero-Day Exploit (CVE-2024-4671)

Google has released a critical security update for Chrome to address a zero-day vulnerability actively exploited by hackers. 

Update your browser to version 124.0.6367.201/.202 IMMEDIATELY.

By Rodger Mansfield, Technology Editor

May 11, 2024

Have you updated your Google Chrome browser recently? 

If not, you may be at risk. Google has issued an urgent security patch to address a zero-day vulnerability actively exploited by cybercriminals. 

Here's a Cool Tip.  Update Chrome Immediately!

What is a Zero-Day Exploit?

A zero-day exploit is a software vulnerability that hackers discover and exploit before the software developer can release a patch. 

This makes them incredibly dangerous because there's no defense against them until a fix is available.

The CVE-2024-4671 Vulnerability

The vulnerability in question, tracked as CVE-2024-4671, exists in Chrome's Visuals component. 

It's a "use-after-free" issue that can potentially allow attackers to execute malicious code on your device remotely. 

This could lead to data theft, malware installation, or other harmful actions.

Why You Need to Update Immediately

This zero-day exploit is already being used in the wild, meaning your computer is at risk if you haven't updated Chrome. 

While Google hasn't released details about the attacks, the urgency of the update indicates the threat is serious.

Here's how to do it.

1. Launch your Google Chrome browser.
2. In the top right corner, click the three vertical dots.
3. Hover over "Help" and click "About Google Chrome."
4. Chrome will automatically check for updates and install them if available.
5. After the update is installed, click "Relaunch" to restart Chrome.

fig. 1 - Update Chrome Immediately

The Benefits of Updating Go Beyond Security

• Enhanced Security: Protect yourself from this specific exploit and other potential threats.
• Improved Performance: Updates often include bug fixes and optimizations for a smoother experience.
• New Features: Some updates bring exciting new functionalities to your browser.

A similar zero-day exploit was discovered in Chrome earlier this year (CVE-2024-0519). 

Hackers used it to gain unauthorized access to sensitive information and crash unpatched browsers. 

Conclusion

Updating your Google Chrome browser is a simple yet crucial step to protect yourself from cyber threats. 

Don't delay—update now to version 124.0.6367.201/.202 and safeguard your digital life. 

Remember, cybersecurity is an ongoing battle, and staying updated is your best defense.

AT&T Data Breach: Millions of Customers' Information Exposed on Dark Web

AT&T confirms a data breach potentially exposing the personal information of over 70 million current and former customers.  The company is investigating the source and offering affected customers credit monitoring.

By Rodger Mansfield, Technology Editor

April 2, 2024

Is your personal information safe with AT&T?  

That's the question swirling in the minds of millions of customers after the telecommunications giant confirmed a significant data breach. 

A dataset containing the information of approximately 73 million customers surfaced on the dark web. 

Should you be worried, and what can you do to protect yourself?

Here's a Cool Tip.   Be informed and protect your privacy.

This significant breach raises serious concerns about the security of customer data held by AT&T.  

Affected individuals should remain vigilant in the coming weeks and months to protect themselves from potential identity theft and financial fraud.

AT&T has launched a full-scale investigation into the data breach incident. 

While they've confirmed some AT&T-specific data was present, the full scope of the exposed information and its original source remain under investigation.  

Preliminary findings suggest the information dates back to 2019 or earlier.

What information might be exposed?

While the investigation is ongoing, the types of data potentially exposed could include:

• Social Security Numbers
• Contact Details (addresses, phone numbers)
• Account Passcodes
• Other personal identifiers

What AT&T is doing

AT&T is proactively notifying affected customers. 

The company states they will offer credit monitoring services at their expense where applicable.

How to Protect Yourself

• Change Passwords: Change your AT&T account passwords immediately, and update passwords on any other accounts where you may have reused them.
• Monitor Your Accounts: Keep a close eye on your credit reports and financial accounts for any signs of unusual activity.
• Consider Credit Monitoring: Even if not offered by AT&T, consider subscribing to a credit monitoring service for extra protection.
• Be Wary of Scams: Fraudsters may try to capitalize on the breach, so be cautious of phishing emails or suspicious calls.

The Takeaway

Data breaches are an unfortunate reality in today's digital landscape. 

This AT&T incident underscores the importance of taking proactive measures to safeguard your personal information. 

Regularly updating passwords, monitoring your accounts, and utilizing credit monitoring services can significantly reduce your risk of identity theft and fraud.

FBI Warns Parents About Internet Connected Toys

Beware of the toys.  They may be watching, listening and sharing.

That's the warning to parents from the US Federal Bureau of Investigation (FBI) about internet connected toys.

The FBI's Internet Crime Complaint Center (IC3) recently issued a statement to parents "to consider cyber security prior to introducing smart, interactive, internet-connected toys into their homes or trusted environments."

The concern is that the toys could pose identity theft and exploitation threats due to microphones, cameras and geo-location data that is improperly used, shared or stored.  

The full notice is worth reading but here are a few points:

• Only connect and use toys with trusted and secure Wi-Fin internet access.
• Closely monitor children’s activity with the toys (such as conversations and voice recordings) through the toy’s partner parent application, if such features are available
• Ensure the toy is turned off, particularly those with microphones and cameras, when not in use
• Use strong and unique login passwords when creating user accounts (e.g., lower and upper case letters, numbers, and special characters)
• Carefully read disclosures and privacy policies

Should we be concerned?  Maybe to Probably.  It can happen.

Nearly two years, we warned readers about the problem caused by one company.  

In that case, Vtech a major tech toy company, poorly stored sensitive children data on the web.

So the best thing we can do is to be cautious and knowledgeable.

Protect Your Online Accounts with Two Factor Authentication

Gaining access to our online accounts with just a few clicks brings both benefits and drawbacks.

Sure, you can log into your Google, Facebook or Yahoo accounts from wherever you are. 

But so can someone else.

That's why always using secure passwords is a must.

But what else can you do to protect your accounts from nefarious hackers and data breaches?

Two Factor Authentication is the answer.

What?

Two Factor authentication provides an additional layer of protection when you log into your online accounts.

When you login with two factor authentication, you'll receive a special code sent by text to your mobile phone that also must be entered to provide access to your account.

That prevents someone who doesn't know both your password AND this special one-time code from gaining access to your account.

Many of your most popular sites such as Google, Facebook, YAHOO, Twitter and LinkedIn all provide this valuable security feature.

Here's how to enable two factor authentication for Google, Facebook and YAHOO:

Google

• Click HERE to start the Google 2-Step Verification set-up process for your Google account.

Facebook

To start the two factor authentication for your Facebook account:

• Go to your Security and Login Settings by clicking  in the top-right corner of Facebook and clicking Settings > Security and Login.
• Scroll down to Use two-factor authentication and click Edit
• Choose the authentication method you want to add and follow the on-screen instructions
• Click Enable once you've selected and turned on an authentication method

YAHOO

To enable two factor authentication for your YAHOO account:

• Sign in to your Yahoo Account info page.
• Click Account Security.
• Next to Two-step verification, click the On/Off icon .
• Enter your mobile number.
• Click Send SMS to receive a text message with a code or Call me to receive a phone call.
• Enter the verification code | click Verify.
• The next window refers to the use of apps like iOS Mail or Outlook. Click Create app password to reconnect your apps. See the section below for more info.
• Want to turn it off? Simply click the On/Off icon  under Two-step verification.
• Using two-step verification with apps
• Some apps (like iOS Mail, Android Mail, Outlook, and Yahoo messenger for PC) require a specific password to connect that app with Yahoo. If you enable two-step verification, you'll need to create a third-party app password to use in apps like these.

Remove Apple QuickTime To Prevent Hacker Attack

US-CERT, the United States Computer Emergency Readiness Team has issued a warning this week for Windows PC users to remove Apple's QuickTime software from their computers.

Apple has announced that it is ending support for the software.  While the software will continue to work, it is vulnerable to malicious exploitation by hackers.

Apple has detailed instructions HERE on how to remove QuickTime.

QuickTime was Apple's proprietary multimedia software and they aggressively promoted its use for years.  Often, it was a required download with other Apple software such as iTunes software.

So you may have it installed and not even know it.

It's a quick thing to do on my Windows machines.

Uninstall at your first opportunity.

Your PC will thank you.

Edit: added additional information concerning QuickTime.

What to Do If You Are Affected by the Vtech Hack Attack

Vtech, a worldwide provider of electronic products, has been hacked.

Specifically, the Learning Lodge app store used for the interactive toys made by Vtech was attacked.

Millions of users are affected.  Emails, Passwords and other account information was stolen.

The Learning Lodge site is currently offline.

Vtech was quick to point out that credit card information was not involved.

But here's the real problem.  

User's emails, passwords and -- most importantly -- the questions and answers to security questions for password retrieval were stolen.

That means if users used the same email, passwords and security answers on OTHER websites, their credit card and financial information is possibly as risk. 

So what can you do?

Be sure to change the passwords and security question answers of OTHER sites that shared the Vtech password and security answers.

And going forward, do not use the same passwords and security question answers on other sites.

That's hard to do but your online identity is worth protecting.

Affected customers with questions can contact Vtech at the following emails:

• US: vtechkids@vtechkids.com
• Canada: toys@vtechcanada.com
• France: explora_park@vtech.com
