Data Breach and Privacy Loss Cases
Medical Practice Data Breach: HIPPA Issues
In this case, McCann digital forensic investigators were retained by a medical clinic who believed that “a hacker had obtained medical information of our clients.” They were also not sure that the data breach had been stopped, or if more information had been leaked. They first discovered the issue when the client began receiving emails with the content of other patients’ medical information, which included names and detailed lab tests. McCann CIRT team responded and determined the source of the data leak. The leak was fixed in cooperation with the IT provider, and it was determined that the total number of possibly exposed records was minimal. McCann reviewed the network security for additional flaws and discovered a few other possible issues via a complete IVA and EVA. The impacted patients were contacted and changes to the clinics security were implemented.
Public Data Breach: Credit Cards, Bank Records and License Plates
In this case, McCann digital forensic investigators were retained by a toll road to determine the extent of a data breach potentially impacting hundreds of thousands of users of a major toll road. The client was unsure if the data loss was via an external attack or an internal attack conducted by a recently fired director of IT security. McCann investigators were able to determine that the former IT security director had been slowly using client credit card information to steal small amounts of money from many thousands of accounts. A complex attempted cover up by the suspect was not enough to stop our team. McCann investigators worked with the toll road’s security director to document the wiring of funds to the suspect’s bank account.
Hacked Email Account and Distribution of Embarrassing Information
In this case, McCann investigators were contacted to investigate the “hacking” of a high profile executive’s personal email account. The contents of the email account included personal photos, some of which were sexual in nature and would be considered damaging. McCann cyber investigators were able to determine the possible IP address of the hacker, the executive’s former assistant and “scorned ex-lover.” The attorney for our client was successfully able to notify the former assistant and effectively remind her of the consequences of illegally accessing private information. The contents of his email remained private.
Data Breach and Extortion: “Pay or We Release Info”
A law firm had been contacted a few weeks prior with an extortion threat detailing with the disclosure of their private email communications. The extortionist, claiming to be an Eastern European hacker, disclosed that they had gathered three years of emails between the firm’s attorneys and clients and were going to publish them online unless the firm paid them $200K. The hacker provided details of emails between attorneys that would be extremely damaging to the firm. McCann digital forensic investigators were able to determine the timing and source of the email breach. It appeared that the source was the outsourced IT provider. The Eastern European hacker, was using a USA-based IP address that happened to be located at a coffee shop across the street from the tech’s home.
