T-Mobile security breach will be discussed in detail in this article. Almost 2 months ago, T-Mobile confirmed it was the subject of a massive data breach in which the personal information of at least 50 million people was disclosed. This information includes first and last name, date of birth, social security number, and driver’s license information.
The information primarily belongs to the people who applied for accounts with T-Mobile and provided the information for a credit check. This means that even people who are not customers will be affected if they have previously tried to open an account.
T-Mobile security breach list
This is the fourth data breach that the “non-carrier” has suffered in recent years. There were further violations in March 2020, 2019 and 2018. A data breach is an unauthorized collection or use of sensitive personal information that presents a significant risk of identity theft or fraud. Data breaches can result from cybercrime such as hacking or ransomware, or employee mistakes such as B. emailing information to the wrong person.
Below are some steps you can take to help keep your sensitive data safe from hackers, whether or not your data has been implicated in a series of data breaches.
Use a credit monitoring service
Keeping track of your credit report is an easy way to ensure that someone is not misusing your information. Some companies offer free credit monitoring to data breach victims, but it is often temporary. For example, T-Mobile is offering those affected by the latest security breach the McAfee Identity Theft Protection service free of charge for two years. Take advantage of offers like this if your data has been affected by a data breach, but once the limited-time offer expires, you can sign up for another service.
There are several credit monitoring services out there to help you keep an eye on your credit report and using one could mean receiving an alert and hopefully detecting the fake accounts as soon as they occur.
Sign up for the identity theft watch
Monitoring your credit report is an important step; however, there is so much more that can be done with your personal information. In addition to monitoring your Social Security number and credit, an identity surveillance service monitors the dark web for anyone selling or trading your personal information, or making arrests on your behalf. It should reassure you when someone tries to do something with your personal information.
Get a password manager to create and save your login credentials
Using a unique, strong password for every online account you have is an easy way to ensure that breaking a service doesn’t result in malicious people gaining access to more of your online accounts where you have used the same password.
Instead of reusing a password – or a series of passwords – you rely on a password manager to automatically create, save and fill in your credentials. T-Mobile also shares best practices for resetting PINs and passwords with customers to keep their data and connections safe.
Don’t wait to protect your personal information
The most important aspect of taking action after a hack or security breach is reported is not to wait for the affected companies to announce how to deal with it. After you’ve locked your credit and started monitoring services, it’s time to look at suggestions from affected companies.
In response to the breach, T-Mobile offered affected customers free identity theft protection services for two years, but it may be too late for many. With their data leaks available on the Internet, it is only a matter of time before crooks use this data for targeted phishing attacks. These targeted attacks are known as “spear-phishing” and use personal information such as your name, location, and interests to impersonate a trusted source like your boss. Because these attacks are highly personalized, they are much more effective than the more general phishing attacks.
SMS-based 2FA considerations
If you have ever received an SMS with a one-time password to log into your bank or another online service, you have used SMS two-factor authentication, or 2FA for short. Many finances, healthcare, and government organizations use SMS-based 2FA as an extra layer of security to prevent unauthorized access with just a username and password.
However, two-factor authentication using SMS messages isn’t as secure as you can imagine. Because IMSI is the unique identifier of a cell phone’s SIM card, a hacker can use stolen IMSI data to duplicate a person’s SIM card and gain access to their phone number. Then, by requesting that a one-time passcode be sent to the phone number, they can access their victims’ accounts, transfer money from their bank accounts, and even block them entirely.
Cyber security experts have been asking consumers to stop using 2FA SMS for years, citing the growing trend of SIM swap attacks that allow hackers to read their victims’ SMS messages, including those with password codes. Since SMS is built into the infrastructure of cellular networks, the security of SMS-based two-factor authentication depends on the security of those networks – which can be compromised, like the recent breach by T-Mobile.
SMS-based 2FA is popular for its convenience – users don’t need to download another app and can receive text messages on any type of cell phone. However, this convenience reduces the security of SMS messages. Instead, it is advisable using an authentication app like Authy or Google Authenticator for two-factor authentication. Instead of receiving one-time access codes via SMS, you can generate these security codes via the app, which can only be accessed on one device. By restricting 2FA to trusted devices instead of phone numbers, hackers cannot easily access user accounts.
