Hackers, though, are looking at all sorts of targets, not just big brand name companies. 'Even a smaller carrier like T-Mobile with roughly 10% market share still represents tens of millions of customers and massive troves of data,' he said.

'Telecommunication carriers are ideal targets for threat actors,' Levin said.

Unfotunately, Levin said, the general public has become numb to the endless news cycle of data breaches, cyber attacks, ransomware attacks and phishing campaigns. Levin said the possible crimes are nearly limitless and called the information 'an El Dorado for scammers and identity thieves.' 'The T-Mobile breach is of great concern, especially for the 40 million people whose names, Social Security numbers and driver's license details were exposed,' said Adam Levin, founder of CyberScout and host of the podcast 'What the Hack with Adam Levin.' Stolen ID information can be used for all sorts of nefarious activities including enabling crooks to open a credit card in your name, apply for jobless benefits using your ID, rent an apartment, get a job using your Social Security number, file fake tax returns to steal tax refund cash and commit medical identity theft.

Someone who is able to control your phone number can control your online world. Carriers put safeguards in place but the possibility of outsiders taking over your phone number exists, if the right information is available. Schaffer noted that consumers access a great deal on their phones, making the risks of a SIM-swap -where your phone's number can be stolen - quite concerning. If those numbers get out there, experts warn there's a greater threat that bad actors would be able to take over accounts and possibly access your bank account via the app on your phone at some point. International Mobile Equipment Identity numbers are not as commonly available to crooks, as say your birth date, name and Social Security number, so they can be quite valuable to hackers. T-Mobile has not said if IMEI numbers - which are unique identifiers tied to your phone - were compromised. It made the climate ripe for fraudsters,' Schaffer said. But consumers have to be aware that they now must pay closer attention as more information relating to them could be in the hands of bad actors. Hacking incidents may seem so common that we only pay attention to big ones these days. If you keep passwords on your phone - which you shouldn't do - she said you'd want to make sure to delete those passwords, too.
