Apple fighting back against quantum attacks with new security system for iMessage
Apple is giving iMessage a big security boost as the company looks to protect users from future quantum attacks, which are cyberattacks that use the power of quantum computers to break the encryption methods used by most online services today.
While hackers don’t have access to quantum computers just yet, the new upgrade takes away a potential avenue for them down the road. Apple is calling it “the most significant cryptographic security upgrade in iMessage history.”

What is PQ3?
PQ3 is Apple’s new encryption upgrade for iMessage to secure conversations. According to Apple, the upgrade provides level 3 security. iMessage currently uses level 1 protections.

How does PQ3 work?
It uses special codes that are difficult for even quantum computers to break. These codes are constantly changing, making it even harder for anyone to intercept your messages. It works behind the scenes, so you don’t need to do anything to benefit from it.

PQ3 is set to roll out in beta versions of iOS 17.4, iPadOS 17.4, macOS 17.4 and watchOS 10.4 soon. Apple says the upgrade will roll out to all iOS devices by the end of the year.
Why is a new security measure needed?
Regular computers struggle to break the codes used in iMessage. However, powerful quantum computers, which are still under development, could potentially crack these codes. PQ3 protects your messages even if that happens.
While PQ3 is supposed to protect you from future hacks, it also provides a way to stop “harvest now, decrypt later” attacks. Although hackers usually want data or information they can use now, “harvest now, decrypt later” attacks steal your information now and will use a more advanced computer to decrypt it in the future.
What are the 3 major benefits of PQ3?
1) Stronger protection: It makes iMessage more secure against current and future threats.
2) Self-healing: If someone tries to steal your messages, PQ3 can automatically fix the problem and protect future messages.
3) No impact on message size: You won’t notice any difference in how quickly your messages are sent or received.

How to protect yourself from hackers
To prevent hackers from accessing your data now or in the future, you should take some precautions. Here are five tips to follow.
1) Keep your phone software updated
You’ll especially want to update your iPhone when iOS 17.4 is available to help protect you from quantum attacks. You should always keep your iPhone’s software and apps updated regularly as Apple releases patches for vulnerabilities as they are discovered. Updating your phones can also prevent hackers from exploiting security flaws.
2) Change your passwords
Change the passwords for all your online accounts, including your email, social media and banking accounts. Do not use easy-to-guess information such as your birthday or address. Use strong, unique passwords that are difficult to guess, preferably ones that are alphanumeric and, if applicable, include special symbols. Be sure to do this on another device in case there is malware monitoring you on your phone. Consider using a password manager to generate and store complex passwords. It will help you to create unique and difficult-to-crack passwords that a hacker could never guess.
3) Enable two-factor authentication
Enabling two-factor authentication on all your online accounts will add an extra layer of security to your accounts and make it more difficult for hackers to gain access.
4) Have good antivirus software on your phone
Having good antivirus software actively running on your devices will alert you of any malware in your system and warn you against clicking on any malicious links that may install malware on your devices, allowing hackers to gain access to your personal information. Find my review of Best Antivirus Protection here.
5) Watch your connections
When possible, do not connect to unprotected or public Wi-Fi hotspots or Bluetooth connections. Turn off the Bluetooth connection when not in use. On most iPhones, you can choose who to receive files or photos via AirDrop (a Bluetooth feature) from by selecting to receive from no one, people in your Contacts or Everyone. We suggest you set it to “no one” and only turn it on when you are with the person you are sending or receiving a file or photo from.

Kurt’s key takeaways
PQ3 feels like it’s going to be a massive upgrade for iMessage users. While other messaging services use encryption, it doesn’t seem like anything is as focused on quantum computing. If this is as secure as Apple says it is, this would be a gold standard for encryption.
Do you feel more secure using iMessage knowing that Apple is being proactive against future cyberattacks? What would you like to see Apple do to further protect users? Let us know by writing us at Cyberguy.com/Contact.

Microsoft is disabling Office 2019 for Mac next month
Microsoft’s Office 2019 apps for Mac will stop working next month, because the company isn’t renewing a certificate that validates Office licenses. Owners of Office 2019 for Mac are being warned they’ll have to purchase Office 2024 or a Microsoft 365 subscription if they want to continue editing documents.
Microsoft previously promised that “all your Office 2019 apps will continue to function,” when it announced end of support in 2023. The company then quietly updated that support note last month to remove the mention of apps continuing to function, replacing it with “Rest assured that all your Office 2019 apps won’t lose any data.”
Starting on July 13th, Office 2019 for Mac and Office 2021 for Mac will both run in “reduced functionality mode,” allowing people to open files but not edit, save, or create new documents. The reduced functionality will impact Word, Excel, PowerPoint, Outlook, and OneNote.
While Microsoft is providing a certificate update for Office 2021 as it’s still supported until October 13th, 2026, the company is leaving Office 2019 for Mac users out in the cold as support for these apps ended a few years ago. “Office 2019 for Mac reached end of support on October 10, 2023, and no longer receives updates,” says Microsoft. “Because Office 2019 cannot be updated to the required version, this issue cannot be resolved by updating or reinstalling Office 2019 for Mac.”
JimmyTech points out that old versions of Microsoft 365 apps on Mac and iOS will also be affected by this certificate issue, but a simple update will fix it for those users.
Microsoft regularly ends support of software and there’s always the risk you could run into issues running older apps or versions of Windows. It’s still surprising to not see Microsoft make an exception here though, particularly because this certificate issue breaks the main functionality of an app you’ve paid a one-time license fee for.

Android fake call detection warns you about scams
NEWYou can now listen to Fox News articles!
You know that little moment when your phone rings and the name on the screen makes you drop everything?
Maybe it says your spouse, your daughter, your boss or your best friend. You answer because you trust the name. Then the voice sounds familiar too.
That is exactly what makes the latest phone scams so dangerous.

Scammers no longer have to call from a strange number. They can spoof a trusted contact’s phone number. Then they can use AI voice tools to sound like someone you know. Android is now rolling out a new feature called fake call detection to help warn you when that familiar call may be a fake.

What is Android fake call detection?
Android fake call detection is a new protection built into Phone by Google. It is designed to spot suspected spoofed calls when both people on the call use Phone by Google.
Think of it as your phone quietly asking, “Is this call really coming from that person’s device?” If the answer looks suspicious, your phone can show a warning and advise you to hang up. That small alert could stop a scam before fear, panic or confusion takes over.
ANDROID SECURITY UPGRADES OUTSMART SCAMS AND PROTECT YOUR PRIVACY
How Android fake call detection works
The feature works automatically in the background. You do not need to answer a quiz, scan a code or press a button during the call. When a trusted contact calls you, their phone sends a silent confirmation signal to your phone. That signal helps prove the call really came from their device.
If a scammer spoofs your contact’s number, that confirmation signal may be missing. Your phone then checks with your contact’s actual device. If the real device says it is not placing a call, your screen can warn you that the call may be fake.
The system uses end-to-end encrypted RCS technology, so the check happens privately. You can also turn the feature off in Phone by Google settings.
AI DEEPFAKE ROMANCE SCAM STEALS WOMAN’S HOME AND LIFE SAVINGS
Why fake calls are getting harder to spot
For years, caller ID gave people a sense of control. If the name looked familiar, most of us felt safer picking up. That old habit now works in the scammer’s favor.
Scammers can use internet-based calling tools to spoof numbers. That means your phone may display the name of someone you trust, even though the call comes from somewhere else.
Then comes the AI voice trick. With today’s audio tools, scammers can make a fake voice sound shockingly real. They may pretend to be a family member in trouble, a bank employee warning about fraud or a manager asking for urgent help.

That combination makes the call feel personal and immediate. It also makes you more likely to act before you think.
Why Android is adding this protection now
Impersonation scams have become a major global problem. INTERPOL’s March 2026 Global Financial Fraud Threat Assessment cited impersonation fraud as one of the leading contributors to more than $400 billion in global losses.
In the U.S., impersonation scams remain one of the top fraud categories reported to the FTC. Losses reached $2.95 billion in 2024.
GLOBAL SCAM CRACKDOWN LEADS TO 276 ARRESTS
Those numbers tell you why this feature deserves attention. Scammers go where the money is. Right now, they know trusted voices and trusted names can open the door.
Which Android phones get fake call detection?
Google says fake call detection is rolling out globally in Phone by Google this month, starting with Pixel devices.
The feature is available on Android 12 and newer devices with Phone by Google, Contacts and Google Messages installed. It also requires RCS capability in Google Messages.
SAMSUNG MESSAGES ENDING? WHAT ANDROID OWNERS MUST KNOW
There is one key limitation. Both you and the person calling you must use Phone by Google for fake call detection to work.
Phone by Google already comes as the default phone app on many Android devices. If your phone uses a different calling app, you can install Phone by Google from the Play Store and set it as your default phone app.
How Android fake call detection protects you
This feature gives you an extra warning at the exact moment you need it most. That timing is important. Scam calls often rely on emotion. The caller may say someone got arrested, a loved one had an accident or a bank account faces an urgent threat.
SSA IMPERSONATION SCAMS ARE GETTING MORE PERSONAL
When the voice sounds familiar, your guard drops. A warning on your screen can interrupt that emotional rush. It gives you a reason to stop, hang up and verify the story another way.
What Android fake call detection cannot do
This new tool helps, but it cannot protect you from every scam. It may not work if the other person does not use Phone by Google. It also may not cover calls from businesses, unknown numbers or contacts using unsupported devices. So you still need basic scam rules.
If someone asks for money, gift cards, crypto, account codes or remote access to your device, hang up. Then call the person or company back using a number you already trust.
Also, never stay on the line just because the caller tells you to. That is one of the oldest pressure tactics in the scammer playbook.

How to protect yourself from AI voice scams
AI voice scams work because they sound personal, urgent and believable, so your best defense is to slow the conversation down before you act.
1) Create a family safe word
Pick a simple word or phrase that only your close family knows. It should be easy to remember but hard for a scammer to guess. Then, if someone calls with an emergency and asks for money, ask for the safe word. If they cannot give it, hang up and verify the story another way.

2) Pause when the call feels urgent
Scammers want you scared because fear makes people act fast. That is why fake emergency calls often sound intense, emotional and rushed. Take a breath before you do anything. A real loved one, bank or employer will let you verify what is happening.
3) Call back using a trusted number
If a call feels suspicious, hang up. Then call the person back using a number saved in your contacts or one you know is real. Do not use a number, link or instruction the caller gives you. That could send you right back to the scammer.
4) Never send money or codes during the call
Do not send gift cards, crypto, wire transfers or payment app transfers because a caller sounds convincing. Also, never share a one-time passcode, PIN or account login code over the phone. Once scammers get that information, they can move fast.
5) Turn on scam protections on your phone
Use the built-in protections already available on your device. Pixel and Samsung users can enable Scam Detection in the Phone by Google app to help flag suspicious calls. Also, consider using strong antivirus software that includes AI-powered scam protection to help detect scams in texts, online content and deepfake videos. Keep an eye on call warnings too. If your phone tells you something looks risky, treat that alert seriously. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android & iOS devices at Cyberguy.com
6) Keep your phone apps updated
Update Phone by Google, Google Contacts and Google Messages when updates are available. These tools work best when your apps and phone software stay current. Updates often include security improvements, bug fixes and new scam protections.
Here’s how to check for updates on Android:
- Open the Google Play Store app.
- Tap your profile icon in the top right corner.
- Tap Manage apps & device.
- Under Updates available, tap See details.
- Look for Phone by Google, Google Contacts and Google Messages.
- Tap Update next to each app, or tap Update all.
You can also turn on automatic app updates by opening the Google Play Store app, tapping your profile icon, then going to Settings > Network preferences > Auto-update apps. From there, choose whether to update apps over Wi-Fi, over Wi-Fi or mobile data, with limited mobile data or not at all.

Android’s fake call detection is a smart step in the fight against AI-powered phone scams. It recognizes something many people already know: the name on your caller ID no longer proves the person calling you is real. This feature gives Android users another layer of protection when scammers try to hijack trust. Still, the safest move remains simple. Slow down, verify the call and never let panic make the decision for you.

Congress just gave DHS another $70 billion
Congress narrowly voted to fund President Donald Trump’s mass deportation agenda, giving the Department of Homeland Security $70 billion over the next three years.
The house voted 214 to 212 in favor of the reconciliation bill Tuesday, following the Senate’s 52-47 vote last Friday morning. The vote fell largely along party lines. Sen. Lisa Murkowski (R-AK) was the only Senate Republican to vote against it. Rep. Tim Walberg (R-MI), initially voted against the bill — meaning it would have failed — but changed his vote after huddling with House Majority Leader Steve Scalise (R-LA) and Appropriations Chair Tom Cole (R-OK), according to The Hill. No Democrats voted in favor of the funding bill, which was done through a budget reconciliation process to avoid a Democratic filibuster.
In a speech on the House floor ahead of the Tuesday vote, Rep. Mary Gay Scanlon (D-PA) criticized Republicans for using the budget reconciliation process to avoid negotiating with Democrats, and emphasized ICE’s lack of popularity with the American people.
“At its core, this Republican reconciliation budget bill is a statement about priorities, and the priorities represented in this budget bill could not be more out of step with the needs and values of the American people,” Scanlon said.
Scanlon noted that DHS has yet to spend $100 billion of the nearly $200 billion it received under Trump’s One Big Beautiful Bill Act. She added that Trump has not only expanded ICE’s reach by increasingly going after legal immigrants but also weaponized DHS against its critics. The bill, she said, will “supercharge” Trump’s abuses.
After the House markup last Friday, Rep. Rosa DeLauro (D-CT), ranking member of the House Appropriations Committee, noted that the bill not only lacks sufficient reforms but also cuts funding for cybersecurity and TSA, whose workers went weeks without pay during the DHS shutdown.
The funding bill comes at a time of deep unpopularity for ICE. One recent poll found that just 33 percent of voters approve of how the agency is doing its job.
And it comes amid yet another threat from border czar Tom Homan to flood New York City with ICE agents. In an interview with Fox News on Monday, Homan said he would send “more ICE agents than you’ve ever seen” to New York City if the state government passed a bill limiting cooperation with DHS.
“Providing a quarter trillion dollars to an administration promising that the public ‘ain’t seen shit yet’ when it comes to mass deportation is a historic mistake,” Todd Schulte, president of the immigration reform group FWD.us, said in a statement. “Supercharging the funding for these already out of control systems will come with terrible human consequences and continue to be met with increasing opposition from voters.”
Correction, June 9th: A previous version of this story said Rep. Tim Walberg voted against the funding bill. He initially voted against it but then changed his vote to support it.
Update, June 9th: This story has been updated to include comment from FWD.us president Todd Schulte.
