19 Billion Passwords Leaked in 2025: What You Need to Know and How to Protect Yourself

Added on: 08/05/2025 In what cybersecurity experts are calling one of the largest password leaks in internet history, over 19 billion compromised credentials have surfaced in a massive data dump dubbed “RockYou2024.” This trove of exposed data is not from a single breach but a massive aggregation of credentials from more than 200 past incidents, spanning over a decade. First revealed by Forbes, this leak is now widely circulating on hacker forums and underground markets—posing a serious threat to personal and corporate cybersecurity.

What Is the RockYou2024 Password Leak?

The RockYou2024 leak, analysed by cybersecurity researchers at Cybernews, is a 19-billion-entry compilation of previously stolen passwords, many of which are still actively used. The passwords are in plaintext format, which means hackers don’t need to decrypt anything—they can use them immediately.

Key stats from the leak include:
• 19,030,305,929 passwords compiled from global breaches
• 94% of passwords are reused across multiple sites
• Popular entries include “123456”, “password”, and “admin”
• Most passwords are between 8–10 characters and lack complexity
This dataset isn’t just big—it’s weaponisable, giving cybercriminals an enormous arsenal for launching attacks on personal, business, and government systems.

Why This Password Leak Is So Dangerous

1. Credential Stuffing Attacks
Using automated tools, hackers test these passwords on thousands of sites. If you reuse passwords, they’ll likely gain access to your email, bank account, social profiles, or worse.

2. Phishing and Scams
Once attackers have partial information, they can launch targeted phishing campaigns—often using fake emails, phone calls, or messages to extract more sensitive data.

3. Business Security Risks
Employees using compromised credentials for workplace accounts can expose entire organisations to ransomware, data loss, or financial fraud.

4. Brute Force Optimisation
This leak acts as fuel for brute force tools. Because the passwords are real and common, these tools become more efficient and successful.

3. Enable Multi-Factor Authentication (MFA)

Even if a password is leaked, MFA provides an extra layer of protection. Use authenticator apps (like Google Authenticator or Authy) instead of SMS whenever possible.

4. Check If Your Accounts Are Affected

Use breach alert services like:
• Have I Been Pwned
• Cybernews Password Checker

If any of your emails or passwords appear in those tools, update them immediately using Sentrya’s password generator.

5. Watch for Phishing and Scams

After major leaks, phishing campaigns spike. Stay alert for:
• Fake account recovery emails
• Messages pretending to be from banks or tech companies
• Unusual login alerts

If in doubt, don’t click. Visit the service’s official website instead.

The RockYou2024 password leak proves that password reuse is no longer just risky—it’s reckless. With more than 19 billion credentials circulating in the cybercriminal underground, every reused or weak password becomes a liability.

Fortunately, with proactive tools like Sentrya, you can reclaim control of your digital footprint:
• Remove your personal info from data brokers
• Block phishing scams
• Generate ironclad passwords for every account

The internet is more dangerous than ever—but with the right tools, you don’t have to be the next victim.

How to Clean 80% of Spam in 2 Days in 2025

Personal data is the new gold, and as a result, scammers make bank by taking advantage of us — did you know that they made over $1 trillion from scams two years ago? That’s more than half of Canada’s GDP… I’ve seen many people just give up their long-term email accounts just because it got filled with spam, scams and phishing emails — and it’s just sad. I don’t know about you, but I’m pretty emotional about my account I made almost 2 decades ago, and I really don’t want to lose it or just give up on it. This is exactly what pushed my research for a permanent solution to get rid of all the junk from my inbox, and give my account a second chance to life - by the way, my next checklist is made strictly for Gmail (that’s what I’m using), so if you’re an Outlook, Yahoo or other type of user, this might not be for you. Let me dive into what I discovered, how it works and how quickly it turned my inbox around. <h2 class= "text-heading">What I discovered</h2> My journey started about 15 years ago, when I used to get more spam than legit emails in my inbox, and it made me wonder why that happens. I didn’t know much at the time, so I got left with just the question. It wasn’t until 6 years ago when I got a job as a data entry assistant for a start-up operating in the data protection industry, and got introduced to this brand new world - that was my ‘Aha!’ moment. I learned a lot there, found what data is collected about us, consumers, by a lot of companies, how entitled many of them feel to do anything they want with our information, and how a large number of them “get back” at us when we try to distance ourselves from them. In simple terms, from the data they collect about us (name, email, phone number, shopping, browsing etc.), they can generate inferred data, like net worth, how much we’re worth to them as customers, and even predict future spending habits. In terms of “getting back” at us, many of them sell our information to others as soon as we unsubscribe from their marketing emails — this way they make up some of the loss resulted from their inability to market their products directly to us. <h2 class= "text-heading">How it works (how I turned my inbox around)</h2> It took me a good while to figure out how to get rid of spam and junk. I first started to look at how I can filter out these types of emails, but since even tech giants like Google or Microsoft haven’t figured it out, I clearly had no chance of doing it, especially by myself. And then it clicked! Instead of chasing after scammers, which use an email or domain as a one-time thing, where they send a bunch of scams once and switch to a different email/domain, I asked myself - what’s constant? Scammers or actual subscriptions? I think it’s pretty obvious that subscriptions are constant for a lot of us. We may have hundreds of opened accounts, but in reality, we use only a handful. So I started fiddling with some filters to see what would happen if I changed my inbox to accept emails only coming from a set list of senders. In 2 days, I got only 2 or 3 emails after I set up that filter. This was my “holy sh*t” moment, and it changed my inbox ever since. I made this filter (along with some other things) into a digital product, but I want to share the “secrets” here with you, so you can get a better email experience, and avoid having to give up on it. Here’s how to create a complete and comprehensive filter: - Make a list of services and subscriptions you still need, and are important to you (important in the next step) - Click on the filter icon in Gmail’s web app, and add the list you made in the “Doesn’t have” field using this format: {(from:sender1 OR from:sender2 OR from:sender3)} - Next, select the “Delete it” option. This way, all emails not included in your filter will be sent to trash, and permanently deleted in 30 days The best thing about this is that it clears all unwanted emails (junk, spam, scams and phishing), and ensured you won’t miss new emails since they’ll just be sent to trash - you can then update the filter and add the new sender to it next. Of course, this will you take you some time to do, but it’s not impossible or overwhelming. Now to the ‘selling’ part - I mentioned that I made this into a digital product called <a href= "https://sentrya.net" class= "content-link">sentrya.net</a>. Sentrya is for privacy-conscious people who don’t want to spend hours manually searching for subscriptions and creating the filter I mentioned earlier. Basically, Sentrya does all the heavy lifting for you, saves you time and gives you peace of mind. Here’s a short comparison between using Sentrya and doing it yourself: Do it yourself: - It’ll take you a few hours gathering all (or almost all) subscriptions - You have to remember to look in your Trash folder every time a new sender emails you - You need to manually update the filter if you want to add a new sender to it With Sentrya: - It takes about 10 minutes to see a list of active subscriptions - You select (mark as Important) the ones you need - Create the filter with a tap - Get notified when a new sender emails you - Update the filter with a tap This is available for free on Sentrya - Remove your information from unwanted subscriptions (to avoid data selling) - Remove your information from a lot of data brokers (avoid having spammers buying your data) - Find if and when your data appears on the dark web These are available under paid plans Thanks for reading all the way here, and I hope you found this article to be useful in saving your email account :) PS: If you know someone on the brink of giving up on their email, send them this article and spare them the heartache of losing their account Read more

Morocco CNSS Data Breach: A Wake Up Call for Consumer Data Protection

In April 2025, Morocco experienced a significant cybersecurity incident when the National Social Security Fund (Caisse Nationale de Sécurité Sociale – CNSS) was compromised. The breach resulted in the unauthorised release of sensitive data pertaining to millions of Moroccan workers and hundreds of thousands of businesses. The fallout from this breach has raised serious concerns about consumer privacy and the adequacy of data protection measures. <h2 class= "text-heading">The CNSS Breach: What Happened?</h2> On April 8, 2025, a hacker group identifying itself as JabaRoot DZ claimed responsibility for the cyberattack on CNSS. The group leaked over 50,000 official documents, including personal identification numbers, salary declarations, employment contracts, and correspondence involving foreign diplomatic entities. The leaked data was disseminated through various channels, including encrypted messaging platforms and public file-sharing websites. Cybersecurity analysts suggest that the attackers may have exploited vulnerabilities in outdated file storage protocols or gained access through compromised administrator accounts. The breach potentially began weeks or months before the data was released, allowing the attackers ample time to exfiltrate information undetected. <h2 class= "text-heading">Implications for Consumer Privacy</h2> The CNSS breach has exposed nearly 2 million employees and approximately 470,000 companies to potential risks, including identity theft, financial fraud, and targeted phishing attacks. The leaked information encompasses a wide range of personal and financial data, making it a valuable resource for malicious actors. This incident underscores the vulnerabilities inherent in centralised data repositories and the critical need for robust cybersecurity measures to protect consumer information. It also highlights the importance of transparency and prompt communication from institutions in the event of data breaches. <h2 class= "text-heading">Sentrya: Empowering Consumers to Protect Their Data</h2> In the wake of such breaches, you must take proactive steps to safeguard your personal information. <a href= "https://sentrya.net" class= "content-link">Sentrya</a> offers a comprehensive solution designed specifically for individual users.

Trump Administration Reverses Data Privacy Protections Exposing Americans to Increased Risks

In a significant policy reversal, the Trump administration has dismantled a Biden-era initiative aimed at limiting the sale of Americans’ personal data by data brokers. This move raises substantial concerns about consumer privacy and national security. <h2 class= "text-heading">Background: The Biden-Era Initiative</h2> Under President Biden, the Consumer Financial Protection Bureau (CFPB) proposed regulations to subject data brokers to oversight akin to credit bureaus. The goal was to protect consumers from the unregulated sale of sensitive personal information, which could be exploited for identity theft, scams, and even national security threats. <h2 class= "text-heading">The Reversal and Its Implications</h2> On May 14, 2025, the CFPB announced the withdrawal of the proposed regulations, stating that they no longer align with the bureau’s policy objectives. Consumer advocacy groups, such as Consumer Reports, have expressed alarm, warning that this decision leaves consumers vulnerable to scams and identity theft. The rollback also includes the withdrawal of proposals related to digital payment technologies and the prohibition of certain terms in consumer finance products. <h2 class= "text-heading">Risks to Consumer Privacy</h2> The unregulated sale of personal data poses several risks: • Identity Theft: Personal information can be used to impersonate individuals, leading to financial loss and reputational damage. • Scams and Phishing: Data brokers can sell information to malicious actors who craft targeted scams and phishing emails. • National Security Threats: Sensitive data about government officials and military personnel can be exploited by foreign adversaries for espionage. <h2 class= "text-heading">Sentrya: A Consumer-Focused Solution</h2> In light of these developments, consumers seeking to protect their personal information can turn to services like <a href= "https://sentrya.net" class= "content-link">Sentrya</a>. Sentrya offers tools to remove personal data from the web and data brokers, and to clear inboxes of scams and phishing emails.
