Insider threats have to be taken seriously and accounted for in some form or manner. Although business owners would hope this would not be an issue, and employees can be trusted, at times it still is. Business owners or senior management should always be aware of the potential for insider issues since an attack from the inside has the potential to be devastating, especially when the insider is acting maliciously.
A recent and unfortunate incident involved SunTrust. One of their former employees in February 2018 attempted to steal data on an estimated 1.5M clients. The prior employee’s intent was to sell this to a third party for criminal purposes.
Any data stolen is not a good thing for the institution and the clients. In this case, it could have been much worse. The data stolen was the client’s name, their address, phone number, and account balances. Fortunately, the PII (e.g. social security number, account number, PIN, User ID, password, or driver’s license number) was not.
Although the prior employee did work to copy the data, the employee was not able to remove the data from the bank.
In other insider malicious attacks, the results have been far worse. The more data that is stolen and exfiltrated, the greater level of potential liability. To alleviate a majority of this potential issue, the businesses should put in place a robust program or set of programs to monitor the behavior of employees. This would act to safeguard the data and report issues in a timely manner.
