Data breaches are becoming more prevalent, affecting organizations across all industries without exception. In this post, we'll discuss some of the most significant data breaches that happened in 2022.
Twitter Data Breach 2022
In July 2022, a cybercriminal using the pseudonym 'devil' made a post on the hacking forum BreachForums claiming to possess the information of 5.4 million Twitter accounts, which they intended to sell.
The stolen data included email addresses and phone numbers of various entities such as celebrities, companies, and general Twitter users known as "OGs". OGs are Twitter handles that are short, consisting of one or two letters, or a desirable word as a screen name, such as a first name with no misspelling, numbers, or punctuation. The hacker 'devil' stated that they would not accept offers below $30,000 for the database.

Advocate Aurora Health
Advocate Aurora, a non-profit health system that runs hospitals in Illinois and Wisconsin, experienced a data breach that affected 3 million patients.
According to the health system, certain patient information was shared with other companies due to the use of tracking technologies such as pixels from Facebook and Google on its websites.
The pixels were used to monitor patient trends and preferences but were disabled after the breach. The health system stated that patient information was transmitted through pixels and other technologies on its patient portals, MyChart and LiveWell websites, and scheduling widgets. As a precautionary measure, Advocate Aurora is assuming that all users of the affected accounts and widgets may have been impacted, although it has not found any evidence of fraudulent activity. The health system also mentioned that the use of pixels would be unlikely to result in identity theft or financial harm.

BidenCash Data Breach 2022
Dark web platforms called carding marketplaces facilitate the exchange of stolen credit card information among users who seek to commit financial fraud, typically involving substantial amounts of money. On October 12, 2022, the carding marketplace named BidenCash made public the information of 1.2 million credit cards at no cost. The posted file contained data on credit cards that will expire between 2023 and 2026, as well as other details required for online transactions.
BidenCash had previously disclosed the details of several thousand credit cards in June 2022 to promote the platform. However, after experiencing a series of DDoS attacks, the carding marketplace was compelled to establish new URLs in September, and some cybersecurity experts suggested that this latest release of information could be another attempt at an advertisement.
