BPASS is the safest and most modern password management platform in Brazil. The ideal solution for you, your team or company. Enterprise-level security with the practicality you need.
The material was reportedly found in a compilation of around 30 different databases, with millions and even billions of records. Although the exact volume of unique data is under question, the alert has been issued: passwords may be being used by criminals on a large scale.
Despite the alarming scale, cybersecurity experts urge caution. The company Bleeping Computer stated that part of the information may be made up of recycled old data — which has already happened in previous cases, such as RockYou2024, which also caused a stir by revealing almost 10 billion passwords, many of which had already been compromised in previous leaks.
Is this really new data or an inflated compilation?
The debate revolves around the authenticity and currentness of the data. Cybernews claims that the files contain recent information, much of it obtained through infostealers — malicious software that invades devices and extracts confidential information without the user noticing.
On the other hand, the company Hudson Rock argues that, to reach the 16 billion passwords mentioned, it would be necessary to invade around 320 million computers — which raises doubts about the plausibility of the number. The company considers the estimate "inflated" and claims that the data may contain many repetitions, outdated information or even artificially generated credentials.
The impact on Brazil and the world
There is still no official confirmation that Brazilian users are among those affected. However, the largest database on the list is potentially linked to Portuguese-speaking populations, which raises a red flag for Brazilians.
Researcher Troy Hunt, creator of the famous Have I Been Pwned website, which monitors leaks, stated that he is still investigating whether the new database can be integrated into the platform. The FBI, in turn, issued statements reinforcing guidelines against phishing via SMS and warning about the risk of scams linked to these leaks.
How to protect yourself: recommendations from experts
In view of the massive exposure of credentials, digital security professionals list immediate actions to mitigate risks:

Every week, technological advances push the boundaries of science fiction. What once seemed like a distant dream is becoming reality – and sometimes a nightmare. From DARPA’s wireless energy transmission to the invasion of humanoid robots in Chinese hotels, to Tesla’s RoboTaxis stumble, the world watches, with both fascination and fear, as a new era dawns.
Brazil has come to a standstill in the face of a brutal tragedy that took place in Itaperuna, in the interior of Rio de Janeiro. A 14-year-old teenager confessed to having shot and killed his father, mother and 3-year-old brother, in what is already considered one of the most shocking crimes of the year in the country. The case, which sounds like a movie script, reveals a complex and dark scenario
As the clashes between Israel and Iran escalate — with missile exchanges since June 13 — fears of a global conflict are also growing. However, instead of outright panic, many Gen Zers are turning to dark humor to cope with the tension, creating memes that are going viral on TikTok, Instagram and X (formerly Twitter).
