16 Billion Accounts Compromised in Largest Data Breach Ever — Big Tech on High Alert

According to cybersecurity researchers, they have recently discovered a vast database that contains over 16 billion usernames and passwords, rendering it the most significant data exposure in history.

As per recent reports, the passwords that were revealed were probably created by several thieves who stole usernames and passwords using different types of infostealing software.

It turns out that these login credentials were collected from a variety of sources, including developer portals, business platforms, social media, and VPNs. Between tens of millions to over 3.5 billion records with accounts from Google, Apple, Facebook, GitHub, Telegram, and other platforms were found in 30 publicly available datasets of varying sizes, according to the researchers.

 According to the study, "none of the exposed datasets were reported previously," with the exception of the Jeremiah Fowler-reported collection that included over 184 million passwords.

Blueprint of Mass Exploitation

Researchers go on to say that this is a roadmap for broad exploitation rather than merely a leak. Cybercriminals now have unparalleled access to personal credentials that may be exploited for identity theft, account takeover, and highly targeted phishing, since more than 16 billion login records have been made public.

The structure and recentness of these databases are particularly worrisome; they are not merely repeated breaches from the past. This is large-scale, new intelligence that can be used as a weapon. Additionally, these recently found datasets were only made available online for a short time utilising unprotected Elasticsearch and object storage instances.

This was sufficient for security researchers to find the dataset without discovering who was in possession of it. According to the research, most of the data that was exposed comes from "a mix of details from stealer malware, credential stuffing sets, and repackaged leaks."

Furthermore, these databases probably contain some duplicate information, even though there is no way to compare them. Because of this, it is challenging to estimate the number of individuals impacted by the data breach.

Datasets Recovered Followed a Set Pattern

The majority of the information in these datasets had a specific format, consisting of a URL followed by a username and password. For those who don't know, this is precisely how malware that steals information gathers and transmits it to threat actors.

The researchers also discovered that phishing efforts, ransomware attacks, business email compromises, and account takeovers frequently employ these massive datasets of usernames and passwords.

Tokens, cookies, and metadata were also included in these accessible datasets, making them risky for businesses and services without multi-factor authentication. Additionally, some of these were only referred to as "credentials" and "logins".
