183 million email passwords leaked: Check yours now
NEWYou can now listen to Fox News articles!
A massive online leak has exposed more than 183 million stolen email passwords gathered from years of malware infections, phishing campaigns and older data breaches. Cybersecurity experts say it is one of the largest compilations of stolen credentials ever discovered.
Security researcher Troy Hunt, who runs the website Have I Been Pwned, found the 3.5-terabyte dataset online. The credentials came from infostealer malware and credential stuffing lists. This malware secretly collects usernames, passwords and website logins from infected devices.
Researchers say the data contains both old and newly discovered credentials. Hunt confirmed that 91% of the data had appeared in previous breaches, but about 16.4 million email addresses were completely new to any known dataset.

The real risk behind the password leak
The leak puts millions of users at risk. Hackers often collect stolen logins from multiple sources and combine them into large databases that circulate on dark web forums, Telegram channels and Discord servers.
If you have reused passwords across multiple sites, attackers can use this data to break into your accounts through credential stuffing. This method tests stolen username and password pairs on many different platforms.
The risk remains real for anyone using old or repeated credentials. One compromised password can unlock social media, banking and cloud accounts.

Google responds to the reports
Google confirmed there was no Gmail data breach. In a post on X, the company stated “reports of a Gmail security breach impacting millions of users are false. Gmail’s defenses are strong, and users remain protected.”
Google clarified that the leak came from infostealer databases that compile years of stolen credentials from across the web. These databases are often mistaken for new breaches when, in fact, they represent ongoing theft activity. Troy Hunt also confirmed the dataset originated from Synthient’s collection of infostealer logs, not from a single platform or recent attack. While no new breach occurred, experts warn that leaked credentials remain dangerous because cybercriminals reuse them for future attacks.
How to check if you were exposed
To see if your email was affected, visit Have I Been Pwned. It is the first and official source for this newly added dataset. Enter your email address to find out if your information appears in the Synthient leak.
Many password managers also include built-in breach scanners that use the same data sources. However, they may not yet include this new collection until their databases update.
If your address shows up, treat it as compromised. Change your passwords immediately and turn on stronger security features to protect your accounts.

9 steps to protect yourself now
Protecting your online life starts with consistent action. Each step below adds another layer of defense against hackers, malware and credential theft.
1) Change your passwords immediately
Start with your most important accounts, such as email and banking. Use strong, unique passwords with letters, numbers and symbols. Avoid predictable choices like names or birthdays.
Never reuse passwords. One stolen password can unlock multiple accounts. Each login should be unique to protect your data.
A password manager makes this simple. It stores complex passwords securely and helps you create new ones. Many managers also scan for breaches to see if your current passwords have been exposed.
Next, check whether your email has been caught in a recent credential leak. Our No. 1 password manager pick includes a built-in Breach Scanner that searches trusted databases, including the newly added Synthient data from Have I Been Pwned. It helps you find out if your email or passwords have appeared in any known leaks. If you see a match, change any reused passwords right away and secure those accounts with strong, unique credentials.
Check out the best expert-reviewed password managers of 2025 at Cyberguy.com.
2) Enable two-factor authentication (2FA)
Turn on 2FA wherever possible. It adds a powerful second layer of defense that blocks intruders even if they have your password. You will receive a code by text, app or security key. That code ensures only you can log in to your accounts.
3) Use an identity theft service for continuous monitoring
Identity Theft companies can monitor personal information like your Social Security number (SSN), phone number and email address, and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals. It’s a smart way to stay one step ahead of hackers.
See my tips and best picks on how to protect yourself from identity theft at Cyberguy.com.
4) Protect your devices with strong antivirus software
Infostealer malware hides inside fake downloads and phishing attachments. A strong antivirus software scans your devices to stop threats before they spread. Keep your antivirus updated and run frequent scans. Even one unprotected device can put your whole digital life at risk.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

5) Avoid saving logins in your web browser
Browsers are convenient but risky. Infostealer malware often targets saved passwords in your web browser.
6) Keep software updated
Updates fix security flaws that hackers exploit. Turn on automatic updates for your operating system, antivirus and apps. Staying current keeps threats out.
7) Download only from trusted sources
Avoid unknown websites that offer free downloads. Fake apps and files often contain hidden malware. Use official app stores or verified company websites.
8) Review your account activity often
Check your accounts regularly for unusual logins or device connections. Many platforms show a login history. If something looks off, change your password and enable 2FA immediately.
9) Consider a personal data removal service
The massive leak of 183 million credentials shows just how far your personal information can spread and how easily it can resurface years later in aggregated hacker databases. Even if your passwords were part of an old breach, data like your name, email, phone number or address may still be available through data broker sites. Personal data removal services can help reduce your exposure by scrubbing this information from hundreds of these sites.
While no service can guarantee total removal, they drastically reduce your digital footprint, making it harder for scammers to cross-reference leaked credentials with public data to impersonate or target you. These services monitor and automatically remove your personal info over time, which gives me peace of mind in today’s threat landscape.

Google pulls AI overviews for some medical searches
In one case that experts described as “really dangerous”, Google wrongly advised people with pancreatic cancer to avoid high-fat foods. Experts said this was the exact opposite of what should be recommended, and may increase the risk of patients dying from the disease.
In another “alarming” example, the company provided bogus information about crucial liver function tests, which could leave people with serious liver disease wrongly thinking they are healthy.

10 ways to protect seniors from email scams
Cyber expert shares tips to avoid AI phishing scams
Kurt ‘The CyberGuy’ Knutsson shares practical ways to avoid falling victim to AI-generated phishing scams and discusses a report that North Korean agents are posing as I.T. workers to funnel money into the country’s nuclear program.
NEWYou can now listen to Fox News articles!
Email scams have become one of the fastest ways scammers steal money from older adults. A single click can expose bank accounts, personal data and retirement savings built over a lifetime. That growing risk is what prompted Bob to write to us with a question many families are now facing:
“My friend’s father is 95 and absolutely lives through his phone/laptop. He refuses to give up either and often clicks on email links. A few years ago, he got caught up in a gift card scam that almost cost him his life savings. It’s not taking away the car keys anymore; it is taking away the email and access to online banking! What do you recommend that his daughter do to protect his online presence?”
Bob is right. For many seniors, email and online banking have replaced car keys as the most dangerous access point. The goal is not to take devices away. It is to quietly put guardrails in place so one bad click does not turn into a financial disaster.
Here is a practical plan families can actually use.

1) Separate money from daily email use
Start by limiting how much damage a single click can cause. If possible, remove online banking access from the devices used for email. When that is not realistic, open a second checking account with only everyday spending money and link it to a debit card for routine purchases.
Keep primary savings accounts offline or set to view-only access. If available, require in-branch or phone verification for transfers above a set amount. This way, even if credentials are compromised, the largest accounts remain protected.
2) Lock down email to stop scams targeting seniors
Email is the number one entry point for scams targeting seniors. Strong filtering matters. Use an email provider with advanced spam protection, such as Gmail or Outlook.com. In the email settings:
- Turn off automatic image loading
- Disable link previews
- Block or auto-quarantine attachments from unknown senders
- Automatically move messages from unknown senders to a Review folder
If available, enable warnings for emails that use familiar display names but come from unfamiliar addresses. This helps stop impersonation scams that pretend to be family, banks or service providers. These steps slow scammers down and reduce impulse clicks before damage happens.
Email is dominant, but voicemail and callback scams are also growing fast among seniors, often as a follow-up to phishing emails. If possible, silence unknown callers and block voicemail-to-email transcription for unfamiliar numbers, since many scams now start with urgent callback messages rather than links.
Email scams often start with messages that look routine but hide urgent threats designed to trigger quick clicks. (Kurt “CyberGuy” Knutsson)
3) Add a trusted second set of eyes
Next, add safety nets that notify family members when something looks wrong. Enable banking alerts for large withdrawals, new payees, password changes, unusual logins and new device sign-ins. Add his daughter as a trusted contact wherever the bank allows it. If available, enable delays or approval requirements for first-time transfers to new payees. This creates a cooling period that can stop scam-driven transactions. For email accounts, set up a recovery contact so that his daughter is notified immediately if someone attempts to access or reset the account.
Enable two-factor authentication (2FA) on email and banking accounts, but pair it with device and transfer alerts, since many scams now succeed even when 2FA is enabled.
4) Harden devices so clicks do not equal catastrophe
Devices should be set up to fail safely. Keep operating systems and browsers updated. Make sure the laptop uses a standard user account instead of an administrator account. This prevents software from installing without approval. Install real-time protection that blocks scam sites before they load. Strong antivirus software helps block malicious links and fake login pages automatically.
The best way to safeguard yourself from malicious links that install malware, potentially accessing your private information, is to have strong antivirus software installed on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

5) Use a password manager to block fake logins
Password reuse makes scams far more dangerous. Fake pop-ups and lookalike websites are designed to trick people into typing usernames and passwords by hand. A password manager removes that risk by storing credentials securely and autofilling them only on legitimate websites. If a page is fake or malicious, the password manager will not fill anything. That simple refusal often prevents account takeovers before they start. Password managers also reduce frustration by eliminating the need to remember or reuse passwords across email, banking and shopping accounts. When set up correctly, this protection works quietly in the background on both phones and laptops.
Many phishing scams no longer rely on obvious fake emails. They rely on realistic login pages. Autofill protection is one of the most effective ways to stop these attacks without changing daily habits.
Next, see if your email has been exposed in past breaches. Our No. 1 password manager pick includes a built-in breach scanner that checks whether your email address or passwords have appeared in known leaks. If you discover a match, immediately change any reused passwords and secure those accounts with new, unique credentials.

6) Freeze credit and monitor identity exposure
If scammers already have personal information, prevention alone is not enough. Freeze credit with Experian, TransUnion and Equifax to prevent new accounts from being opened. Also, place freezes with ChexSystems and the National Consumer Telecom and Utilities Exchange to stop criminals from opening bank accounts, phone lines, or utility services in his name.
If possible, request an IRS Identity Protection PIN to prevent tax-related identity theft.
Add ongoing identity monitoring so suspicious activity triggers alerts quickly. Identity Theft companies can monitor personal information like your Social Security number (SSN), phone number and email address, and alert you if it is being sold on the dark web or being used to open an account. They can also assist you in freezing your bank and credit card accounts to prevent further unauthorized use by criminals.

7) Set clear rules around scams and payments
Technology helps, but expectations matter. Have one calm conversation and agree on simple rules:
- No gift cards for urgent emails or texts
- No sending money through unfamiliar apps or cryptocurrency
- Always call a trusted family member before acting on urgency
Post these rules near the computer or phone. Visual reminders reduce panic decisions. Also, before setting rules, choose one primary trusted contact. Multiple helpers can slow response during urgent scams and create confusion when fast decisions matter. That person should be the default call for anything urgent involving money, account access, or unexpected requests.

8) Reduce exposure with a data removal service
Scammers often find seniors by pulling personal details from public data broker websites. These sites publish phone numbers, addresses, relatives and age information that make targeting easier. A data removal service works behind the scenes to opt seniors out of these databases and reduce how much personal information is publicly available online. Fewer exposed details means fewer scam calls, fewer phishing emails and fewer impersonation attempts. This step does not stop every scam, but it significantly lowers how often seniors are targeted in the first place.

9) Use senior-friendly monitoring tools the right way
Many tools designed for child safety also work well for seniors when used thoughtfully. When configured correctly, they add protection without interfering with daily routines.
Below are device-specific steps families can use today.
iPhone and iPad
Apple’s built-in Screen Time tools provide strong protection without installing extra apps.
What to set up:
- Open Settings and tap Screen Time
- Turn on Screen Time for the device
- Tap Content & Privacy Restrictions and turn it on
- Under App Store Purchases, set app installs to Don’t Allow
- Tap Web Content and limit access to approved or safe websites
- Set a Screen Time passcode known only to the caregiver
If the caregiver wants remote visibility or control, add the device to Family Sharing and manage Screen Time from the caregiver’s Apple ID.
BROWSER EXTENSION MALWARE INFECTED 8.8M USERS IN DARKSPECTRE ATTACK
Why this helps: It blocks many scam sites, prevents accidental app installs and stops fake update prompts from causing damage.
Android phones and tablets
Android offers built-in protections and optional supervised controls.
What to set up:
Settings may vary depending on your Android phone’s manufacturer
- Open Settings and go to Digital Wellbeing & parental controls
- Turn on parental controls for the device
- Restrict app installs and require approval for new downloads
- Enable Safe Browsing and website filtering
- Turn on alerts for new app installs and account changes
For families who want shared oversight, Google Family Link can be used to supervise app installs and receive alerts, as long as both parties agree.
Why this helps: Many Android scams rely on fake app installs. These settings block that path.
Windows computers
Windows protection works best when user accounts are set correctly.
What to set up:
- Create a standard user account for daily use
- Keep the caregiver account as the only administrator
- Turn on Microsoft Family Safety if available
- Enable SmartScreen and browser phishing protection
- Block software installs without administrator approval
Why this helps: Malware often installs silently on admin accounts. This setup prevents that.
Mac computers
macOS includes built-in controls similar to those on iPhone and iPad.
What to set up:
- Create a standard user account for the senior
- Limit administrator access to a trusted caregiver
- Open System Settings and enable Screen Time
- Restrict app installs and system changes
- Keep built-in malware and phishing protections enabled
Simple digital guardrails can reduce risk while allowing seniors to keep their devices and independence. (Kurt “CyberGuy” Knutsson)
Why this helps: It prevents fake software updates and malicious downloads from installing.
10) Best practices for all devices
- Use alert-only or limited-control settings whenever possible
- Review settings together so expectations are clear
- Avoid tools that feel invasive or confusing
- Focus on blocking harm, not monitoring behavior
This is not about spying. It is about adding digital seatbelts while preserving independence. When used respectfully, these tools reduce risk without changing daily habits.
Pro Tip: Use a secure email service for added privacy
For families looking to go a step further, switching to a secure email service can significantly reduce scam exposure. Privacy-focused email providers are designed to limit tracking, block hidden tracking pixels, and reduce how much data advertisers or scammers can collect from inbox activity. Many secure email services also offer disposable or alias email addresses for one-time signups. If an alias starts receiving spam or scam messages, it can be disabled without affecting the main email account. This makes it easier to keep a primary email address private and limit long-term exposure. Secure email platforms typically include features like encrypted messages, no advertising and stronger privacy controls. While switching email providers is optional, it can be a useful upgrade for seniors who receive large volumes of spam or have been repeatedly targeted by scams.
Why it matters: Less tracking means fewer scam attempts. Aliases reduce how often personal email addresses are exposed, without changing daily habits.

Musk says he’s going to open-source the new X algorithm next week
In 2023, what was then still called Twitter, open-sourced at least portions of the code that decided what it served up in your feed. But that GitHub repository is hopelessly out of date, with the vast majority of the files appearing to be from the initial upload three years ago. Elon Musk says that in seven days, he will open-source X’s new algorithm and finally give people a peek behind the curtain and possibly a technical explanation as to why your feed is 90 percent rage bait.
Elon has always made promises to open-source parts of X, and has followed through to at least some degree, including Grok-1 in 2024. But xAI is now on Grok-3, and the Grok GitHub repository hasn’t been updated in two years. The timing of the announcement open-sourcing the X algorithm is also likely to be met with some suspicion, as Musk is fending off criticism from across the globe and the political spectrum regarding Grok’s willingness to make deepfake nudes.
Musk says this release of the X algorithm will include “all code used to determine what organic and advertising posts are recommended to users.” He also says this will be just the first, with updates coming every four weeks, and that those will include developer notes highlighting any changes. Of course, considering how things played out in 2023, you’ll have to forgive us for taking that promise with a grain of salt.
