As with COMB, the original data in this breach was actually leaked years ago (in 2019). The breach exposed the personal information of over 500 million Facebook users worldwide. The breach: In April, security researchers discovered a trove of Facebook user data being shared in an online hacking forum. For this reason, if you haven’t updated your passwords in a while, or if you’re still not using two-factor authentication (2FA), there’s no time like the present to strengthen your defenses! What’s noteworthy here is the way that older breaches can gain new life as they’re compiled, traded, or sold on hacking forums and the dark web. The takeaway: The COMB breach highlights the long-term nature of the data breach threat, as well as the way that the underground hacking “economy” works. The difference is that now these breached records are available to the bad guys as a single, searchable database. As the name implies, COMB wasn’t a single data breach, but a compilation of numerous data breaches from past years. ![]() COMB comprised credentials from over 3.2 billion users. The breach: The Compilation of Many Breaches (COMB) data breach hit in February, and has been the biggest (by the numbers) data breach of 2021 so far. We’ll focus on data breaches that both affected a large number of people - and that tell us something about the current cybersecurity threat landscape. In this article, we’ll take a look at eight of the most significant data breaches of 2021 so far. We’re at the halfway point of 2021, and it’s already been another big year for data breaches. 8 of the most important data breaches of 2021 (so far)
