• A T-Mobile repeat data breach event resulted from unauthorized access to 200,000 customer accounts, including call records.
  • It is the fourth time T-Mobile has sent a data breach notification since 2018. The T-Mobile data breach in December was the second one in 2020.
  • An investigation into the SolarWinds data hack has not revealed any evidence suggesting the attackers sought or stole mass amounts of personal information. The target appears to be either intellectual property or the personal information of particular individuals for espionage purposes.
  • For information about recent data breaches, consumers and businesses should visit the Identity Theft Resource Center’s (ITRC) new data breach tracking tool, notifiedTM.
  • Keep an eye out for the ITRC’s 15th Annual Data Breach Report. The 2020 Data Breach Report will be released on January 27, 2021. 
  • For more information, or if someone believes they are the victim of identity theft, consumers can contact the Identity Theft Resource Center toll-free at 888.400.5530 or via live-chat on the company website. 

Welcome to the Identity Theft Resource Center’s (ITRC) Weekly Breach Breakdown for January 8, 2021. Each week, we look at the most recent and interesting events and trends related to data security and privacy. We started this podcast and a sister monthly program in 2020 in response to the shifts in privacy, security and identity issues: the changes in how criminals collect and use consumer and, increasingly, business information.

One of the trends that the ITRC has identified, and will explore in a report this spring, is the rise in the number of repeat data breaches, even as the overall number of data events is declining. That leads us to the title of this week’s episode – “Second Verse, Same as the First.”

While most of us were prepping for a socially distanced Christmas celebration, one of the largest mobile telephone companies posted a data breach notice on its website. It was not the first time T-Mobile issued a breach notice; it was the fourth time since 2018.

T-Mobile Repeat Data Breach Event

T-Mobile announced that an unauthorized party accessed a small percent of customer accounts, about 200,000 accounts, in early December 2020. The compromised data may have included call records — such as when a call was made, how long the call lasted, the phone numbers called and other information that might be found on a customer’s bill.

T-Mobile says the hackers did not access names, home or email addresses, financial data and account passwords or PINs. An investigation is on-going.

The December data event is the second time an attacker accessed customer information in the same year. Just months into 2020, a breach of the T-Mobile employee email system allowed criminals to see customer data and potentially misuse it. Information about more than one million prepaid customers was exposed in 2019, and cybercriminals compromised nearly two million accounts in 2018.

A Shift in Data Thieves Tactics

Research conducted by the ITRC shows the number of consumers who report being the victim of more than one identity crime has increased 33 percent in the past 18 months. It comes at a time when data thieves are shifting their tactics and targets. Our research shows they are focusing more on business data and less on mass amounts of consumer personal data.

While data breaches are dropping, cyberattacks are rising. The two are not the same. That’s an important distinction as a large and consequential cybersecurity breach occurred in late December 2020 and is likely still underway.

SolarWinds Data Hack Update

We talked about the attack in our last podcast before the holiday break, but the scope of this attack warrants an update.

Here’s what happened: A group of professional cybercriminals affiliated with the Russian government’s intelligence service was able to insert software into a common technology service used by governments and private companies, known as SolarWinds. An estimated 18,000 organizations have been exposed to the malware, including some of the largest agencies in the U.S. government – the Departments of Commerce, Treasury, Justice, State and most of the Fortune 500.

The good news for consumers is at this point, after nearly a month of investigation, there is no indication the attackers sought or stole mass amounts of personal information. As is common with this particular group of threat actors, the target appears to be intellectual property or the personal information of specific individuals for espionage purposes – not profit.

We will release a detailed report on the impact of identity-related crimes in May. We will issue our report on 2020 data breaches and trends on January 27, just a few weeks from now.
