Each dataset contains a URL alongside usernames and passwords, suggesting that malicious software was used to collect login details from infected devices. While some overlap exists among the records, the overall size and spread of the leak make it difficult to determine how many unique users have been compromised.
Except for one dataset previously identified by cybersecurity researcher Jeremiah Fowler—which included over 185 million unique credentials—most of the remaining 29 databases had not been publicly reported before. These leaked collections are often only temporarily available online before being removed, but new compilations are regularly uploaded, often every few weeks, with fresh data that could be weaponized by cybercriminals. The exact sources and individuals behind these leaks remain unknown.
To avoid falling victim to similar malware attacks, experts advise staying away from third-party download platforms, especially when obtaining software for macOS. Users are encouraged to download apps directly from the Mac App Store or, if not available there, from a developer’s official website. Using cracked or pirated software significantly increases the risk of malware infection.
Phishing scams remain another common threat vector. Users should be cautious about clicking on links in unsolicited emails or messages. Even if a message appears to come from a trusted company, it’s vital to verify the sender’s address and inspect URLs carefully. You can do this by copying the link and pasting it into a text editor to see its actual destination before clicking.
To reduce the chance of visiting malicious sites, double-check the spelling of URLs typed manually and consider bookmarking commonly used sites. Alternatively, using a search engine and clicking on verified results can reduce the risk of visiting typo-squatting domains.
If you suspect your credentials may have been compromised, take immediate action. Start by updating passwords on any affected services and enabling two-factor authentication for added security. It’s also wise to check your financial statements for unauthorized activity and consider placing a freeze on your credit file to prevent fraudulent account openings.
Additionally, tools like Have I Been Pwned can help verify if your email address has been part of a known breach. Always install the latest system and app updates, as they often include crucial security patches. Staying current with updates is a simple but effective defense against vulnerabilities and threats.
