Recent healthcare breaches are similar to past incidents which lead to $112.7M losses

Several healthcare organizations have recently reported data breaches, affecting the data of around 300,000 individuals. The breaches, affecting Central Florida Inpatient Medicine, Kaiser Permanente and Alameda Health System, were all a result of email account breaches, probably stemming from credentials stolen following a phishing attack. Stolen credentials are the main way organizations are breached, as stated in the 2022 version of the Data Breach Investigations Report (DBIR). As threat actors seek to acquire and capitalize on stolen credentials, the number of stolen and compromised credentials is growing, and it has been stated that as of 2022, there are over 24 billion account credentials exposed online, a 65% increase since 2020. 

This simple and ubiquitous means of access has very expensive consequences for data breach victims.

Kovrr’s cyber incidents database, which contains both threat intelligence and financial data on a vast collection of cyber incidents, includes details on many breaches affecting the healthcare industry. 

Example of a similar breach: 

A 2021 data breach of a large US-based healthcare system which exposed personal information of former and current employees and clients (the data of around 150,000 individuals is estimated to have been affected), cost the company a total of $112.7M.

Crypto Hackers Steal $100 Million With Horizon Bridge Attack

It has “begun working with national authorities and forensic specialists to identify the culprit and retrieve the stolen funds.” Horizon, which offers cross-chain transfers between Ethereum and Binance, marks the third major bridge hack this year. In February, hackers stole more than $300 million from the Wormhole bridge. In late March, Ronin Bridge lost about $620 million to hackers. Even before the Horizon hack, money stolen from bridges exceeded $1 billion, researcher Chainalysis has estimated

Confidential Record Leak Leaves CalBar, Lawyers, Clients Exposed

California’s state bar association, which is responsible for licensing and regulating more than 250,000 lawyers, is under scrutiny for a data leak that allowed confidential client complaint and attorney disciplinary record data to be captured by a free court records website. As many as 322,500 such documents were vacuumed up by JudyRecords.com between Oct. 2021 and Feb. 2022, according to a proposed class action filed against the California bar by two lawyers, a former judge, and three people with attorney grievances, all of whom are proceeding anonymously. When a state bar experiences a data breach, confidential information stored in disciplinary files could be a target, and releasing those files could potentially lead to doxing, extortion, or identity theft, as well as to litigation against the bar, according to attorneys who spoke to Bloomberg Law about the matter.
