Why the Microsoft 365 Copilot bug matters for data security
NEWYou can now listen to Fox News articles!
You trust your email security settings for a reason. So when an AI assistant quietly reads and summarizes messages marked confidential, that trust takes a hit.
Microsoft says a bug in Microsoft 365 Copilot allowed its AI chat feature to process sensitive emails since late January.
The issue bypassed Data Loss Prevention policies that organizations rely on to protect private information. Put simply, emails that were supposed to stay locked down were being summarized anyway.

Microsoft 365 Copilot bug summarized confidential emails
Microsoft says a coding error impacted Microsoft 365 Copilot Chat, specifically the “work tab” feature. The AI assistant helps business users summarize content, draft responses and analyze information across Word, Excel, PowerPoint, Outlook and OneNote.
Beginning Jan. 21, an internal bug labeled CW1226324 caused Copilot to read and summarize emails stored in Sent Items and Drafts folders.
The real concern runs deeper. Several of those messages carried confidentiality or sensitivity labels.
Companies apply those labels along with DLP policies to block automated systems from accessing restricted content. Despite those safeguards, Copilot still generated summaries.
We reached out to Microsoft, and a spokesperson provided CyberGuy with the following statement:
“We identified and addressed an issue where Microsoft 365 Copilot Chat could return content from emails labeled confidential authored by a user and stored within their Draft and Sent Items in Outlook desktop. This did not provide anyone access to information they weren’t already authorized to see. While our access controls and data protection policies remained intact, this behavior did not meet our intended Copilot experience, which is designed to exclude protected content from Copilot access. A configuration update has been deployed worldwide for enterprise customers.”
Why the Microsoft 365 Copilot bug matters for data security
AI tools feel helpful. They save time and reduce busy work. But they also rely on deep access to your data. When safeguards fail, even temporarily, sensitive content can move in ways you did not expect.

For businesses, that could mean:
Legal discussions summarized outside intended controls
Financial projections processed despite restrictions
HR communications are exposed to automated analysis
Even if no data leaves the organization, the bypass itself raises concerns about how AI integrates with enterprise security systems.

How Microsoft is fixing the Microsoft 365 Copilot bug
Microsoft says it began rolling out a fix in early February. The company continues to monitor deployment and is contacting some affected users to verify the fix works.
However, Microsoft has not provided a final timeline for full remediation. It has also not disclosed how many organizations were affected.
The issue is tagged as an advisory, which usually signals limited scope or impact. Still, many security professionals will want deeper clarity before feeling comfortable.
What this Microsoft 365 Copilot issue reveals about AI security
This incident highlights something many companies are wrestling with right now. AI assistants sit inside productivity platforms. They need access to email, documents and collaboration tools to work well.

At the same time, those platforms contain your most sensitive information. When AI features expand quickly, security policies must evolve just as fast. Otherwise, even a small code mistake can create unexpected exposure.

Ways to stay safe after the Microsoft 365 Copilot bug
If your organization uses Microsoft 365 Copilot, here are practical steps to reduce risk:
1) Review Copilot access settings
Work with your IT team to confirm which folders and data sources Copilot can access.
2) Revalidate DLP policies
Test sensitivity labels and DLP (Data Loss Prevention) rules to ensure they block AI processing as intended.
3) Monitor advisory updates
Stay current on Microsoft service alerts and verify that the fix is fully deployed in your tenant.
4) Limit AI scope during investigations
If you have concerns, consider temporarily restricting Copilot features until verification is complete.
5) Train employees on AI boundaries
Remind staff that AI assistants can process drafts and send messages. Encourage careful handling of sensitive content.
6) Audit Copilot activity logs
Review audit logs to see whether Copilot accessed or summarized labeled emails. This helps determine actual exposure rather than assumed risk.
7) Review sensitivity label configuration
Confirm that confidential labels are configured to block AI processing where required. Misconfigured labels can create gaps even after a bug is fixed.
8) Reassess retention and draft policies
Because the issue involved Sent Items and Drafts, evaluate whether sensitive drafts should be stored long-term or deleted after sending.
9) Limit Copilot to specific user groups
Instead of enabling Copilot organization-wide, consider a phased deployment to departments with lower sensitivity exposure.
10) Conduct a post-incident security review
Use this moment to reassess how AI tools integrate with compliance controls. Treat it as a learning opportunity rather than a one-time glitch.
Pro Tip: This Copilot bug centers on enterprise controls. Even so, AI tools operate on your devices and accounts, so keeping software up to date and using strong antivirus software adds an important layer of defense.

Considering a more private email provider
Enterprise AI bugs raise a bigger question: how much access should email platforms have to your data in the first place? If you want an added layer of privacy beyond mainstream providers, privacy-focused email services are worth exploring.
Some offer end-to-end encryption, support for PGP encryption and a strict no-ads business model that avoids scanning messages for marketing purposes.
AI WEARABLE HELPS STROKE SURVIVORS SPEAK AGAIN
Many also allow you to create disposable email aliases, which can reduce spam and limit exposure if one address is compromised.
While no provider is immune to software bugs, choosing an email service built around privacy rather than data monetization can limit how much of your information is accessible to automated systems in the first place.
For individuals, journalists and small businesses especially, that added control can make a meaningful difference.

Kurt’s key takeaways
AI assistants are becoming part of daily work life. They promise speed, efficiency and smarter workflows. But convenience should never outrun security.
This Copilot bug may have a limited impact. Still, it serves as a reminder that AI tools are only as strong as the guardrails behind them.
When those guardrails slip, even briefly, sensitive information can move in unexpected ways. As AI becomes more embedded in business software, trust will depend on transparency, fast fixes and clear communication.
Here is the real question: If your AI assistant can see everything you write, are you fully confident it respects every boundary you set? Let us know by writing to us at Cyberguy.com

Dyson’s powerful 360 Vis Nav robovac is down to $279.99 for a limited time
If you’re tired of running your vacuum multiple times just to get the dirt and debris out of the carpets in your living room, Dyson’s 360 Vis Nav is worth a look. It’s one of the more powerful robot vacuums currently available, and now through May 11th (or while supplies last), it’s on sale at Woot for an all-time low of $279.99 ($919 off) with a full two-year warranty.
The last-gen 360 Vis Nav offers a whopping 65 air watts of suction, allowing it to pull dirt, dust, and pet hair from carpets impressively well. In her brief time testing the robovac, my colleague Jennifer Pattison Tuohy said the Dyson “demolished a pile of dry oatmeal in seconds,” adding that she briefly worried it might even suck up the tassels on her large rug (it didn’t). By comparison, many robot vacuums — including Dyson’s new $1,200 Spot + Scrub AI — require multiple passes to fully eradicate the same kind of mess on your floor.
What’s more, the robovac’s small, D-shaped design and the location of its ultra-fluffy brush allow it to dig into edges and corners more effectively than many of the more roundish robot vacuums, while its lower profile lets it easily get under most beds and sofas. The roomy 500ml dustbin also means you likely won’t need to empty it too often, while Dyson’s built-in handle and terrific quick-release button make removing said bin a relatively simple task when it’s time to do so.
While it is undeniably powerful, it’s worth noting that the 360 Vis Nav lacks a few features found on some of its more modern rivals. Although its navigation worked well enough during our testing, it lacks AI-powered obstacle avoidance and doesn’t come with a self-emptying dock. Battery life is also relatively short at around 65 minutes per charge. Nonetheless, if your top priority is quickly removing dust, dirt, and pet hair from carpets without multiple passes, the Dyson remains an option worth considering, especially at this discounted price.

Global scam crackdown leads to 276 arrests
NEWYou can now listen to Fox News articles!
We’ve often warned you about romance scams and crypto “investment” opportunities that feel too good to pass up. Now, there’s a major update that shows just how organized these operations have become.
The Department of Justice and Federal Bureau of Investigation announced a sweeping international operation that led to at least 276 arrests and the shutdown of multiple scam centers tied to cryptocurrency fraud. These networks targeted Americans and drained millions of dollars from victims.
The operation spanned continents and involved coordinated efforts by law enforcement and tech companies.

TOP 5 SCAMS SPREADING RIGHT NOW

How the cryptocurrency scam crackdown unfolded
Authorities worked with partners around the world, including the Dubai Police and law enforcement agencies in Thailand and beyond. Together, they dismantled at least nine scam centers linked to large-scale crypto fraud.
Several suspects now face federal charges in the United States, including wire fraud and money laundering. Investigators say these operations functioned like businesses, with recruitment, management layers and structured systems designed to deceive victims.
Officials made it clear that this effort sends a message. Fraud crosses borders, and enforcement is now doing the same.
How crypto investment scams target victims
These schemes often follow a pattern known as “pig-butchering.” It is a slow, calculated tactic that builds trust before any money is involved.
A scammer may reach out through social media or a messaging app and start a casual conversation. Over time, that interaction turns more personal. In some cases, it feels like a real relationship. Once trust is established, the topic shifts toward investing, often framed as a unique crypto opportunity.
Victims are guided through setting up accounts and transferring funds to platforms that appear legitimate. The dashboards may even show fake gains to build confidence. At that point, control of the money is already gone. Funds are quickly moved through multiple accounts and eventually end up with the scammers.
Many victims are encouraged to keep going, sometimes borrowing money or taking out loans to invest more. By the time the truth becomes clear, the losses can be devastating.
How Meta Platforms, Inc. helped track scam networks
Meta Platforms, Inc. played a key role in the investigation by providing data that helped law enforcement identify and track these networks.
The company says it has taken aggressive action across its platforms. In 2025 alone, Meta removed more than 159 million scam ads and shut down 10.9 million accounts linked to scam centers. More recently, it disabled over 150,000 accounts connected to these networks as part of a coordinated enforcement effort.
“Meta is committed to combatting online fraud and scams, and we are proud to partner with law enforcement in these efforts,” Chris Sonderby, Meta’s vice president and deputy general counsel, said. “We applaud the DOJ and FBI for their leadership in holding criminal scammers accountable and protecting American consumers.”

New tools to stop cryptocurrency scams in real time
Meta is also rolling out new protections across its apps to help users spot scams before they get pulled in.
On Facebook, users may see alerts tied to suspicious friend requests, especially when an account shows unusual behavior such as limited connections or inconsistent location details.
On WhatsApp, new warnings are designed to prevent scammers from linking their own devices to someone else’s account, giving users a chance to pause before approving a risky request.
Messenger is also expanding its scam detection tools. When a conversation shows patterns linked to common fraud tactics, users may receive prompts that explain the risk and suggest actions like blocking or reporting the account.
Why this cryptocurrency scam crackdown matters to you
This operation highlights how organized these scam networks have become. These are not random messages from a single person. They are coordinated groups running structured operations designed to build trust, create urgency and move money quickly.
Even with hundreds of arrests, the threat remains. New networks continue to emerge, often using the same playbook with slight changes. That means staying informed is still one of the most effective ways to protect yourself.
Ways to stay safe from cryptocurrency scams
Scammers follow familiar patterns, which means there are clear warning signs you can watch for and simple steps you can take to protect yourself.
1) Slow down unexpected connections
If someone you do not know reaches out and quickly builds a personal connection, slow things down and question the situation. Scammers rely on momentum, so taking a pause can help you spot inconsistencies.
2) Verify investment platforms before sending money
Before sending money to any investment platform, take time to verify that it is legitimate. A professional-looking website or app does not guarantee it is real. Look for independent reviews and official registration details.
3) Avoid sending crypto to unknown sources
Avoid sending cryptocurrency to individuals or platforms you cannot confirm. Once those transactions go through, they are extremely difficult to recover.
4) Watch for pressure and urgency
Be aware of pressure. If someone pushes you to act quickly or invest more, that urgency is often a warning sign.
5) Use strong antivirus protection
Strong antivirus software can help block malicious links, fake investment sites and other threats before they reach you, adding another layer of defense against scam attempts. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.

6) Limit your personal data exposure
Scammers often rely on publicly available information to build trust. Reducing how much of your personal data appears online by using a data removal service can make it harder for them to target you in the first place. Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting CyberGuy.com.
7) Strengthen your account security
It also helps to strengthen your digital security. Enable two-factor authentication (2FA) on your accounts and use trusted security tools to reduce exposure to malicious links and messages.
8) Report scams as soon as possible
If you believe you have been targeted or defrauded, report it to the FBI’s Internet Crime Complaint Center at ic3.gov as soon as possible.
Kurt’s key takeaways
This global crackdown is a meaningful step forward. It shows what can happen when law enforcement, tech companies and international partners work together. At the same time, these scams are not going away. The tactics will continue to evolve, and new networks will take the place of those that were shut down. Awareness and caution remain your strongest defenses.

Asus chases Elgato with its own secondary touchscreen display
Asus’s latest gaming monitor is a little smaller than usual. The ROG Strix XG129C, announced on Friday, is a 12.3-inch touchscreen IPS display that’s intended to be a sidekick for a larger main monitor, similar to the 14.1-inch secondary display in the 2020 Asus ROG Zephyrus Duo 15. It’s a slightly smaller competitor to Corsair’s Xeneon Edge, which has a 14.5-inch display, but the same 720p resolution.
Asus says the XG129C covers 125 percent of the sRGB color gamut and 90 percent of the DCI-P3 color gamut. It also comes with a one-year subscription for the hardware monitoring tool AIDA64 Extreme, which would usually cost $65. Besides acting as a performance monitor for your PC, sidekick displays like this can also be handy as an extension for streaming or editing setups, much like Elgato’s Stream Deck.
Along with the little XG129C, Asus also announced the ROG Strix OLED XG34WCDMS, a 34-inch RGB Tandem QD-OLED gaming monitor. It features a 280Hz refresh rate and a 3440 x 1440p resolution, and, according to Asus, covers 99 percent of the DCI-P3 color gamut. Asus has not yet officially announced pricing for either display.
