While T-Mobile is giving the victims two years of free identity protection, the company should have done more to protect its customer’s data, considering this isn’t the first time the mobile carrier is being targeted.Ī classic solution is data partitioning. The issue made the access point publicly available on the internet – all the actors had to do was find the gate. T-Mobile could have avoided the attack if the company conducted a proper scoped penetration test and used internal network monitoring tools.Īccording to the hackers, this was a configuration problem on the access point the company uses for testing. A complex organization is generally its own worst enemy with operational debt causing systematic accrual of risk.

Is T-Mobile to blame?Ī data breach as massive as T-Mobile’s usually occurs because of a series of mistakes or an absence of security control. That’s especially true considering that T-Mobile wasn’t aware of the attack until the hackers posted it on the dark web. A malicious insider could have abused their privileges as an authorized user to carry out the attack against T-Mobile’s information systems.Īnd because the user is legitimate, it can be hard to detect these types of attacks. The attack could also have been instigated from inside the company.

The attackers could have used several methods including password cracking software, password sniffers, and dictionary attack, to hack into T-Mobile’s GGSN router.

While there are several attack vectors, the T-Mobile breach could have been a case of a brute force authentication attack against internal systems.Ī brute force attack involves cracking credentials to guess usernames and passwords to gain unauthorized access to a system via trial and error. The attack allows the actors to exploit the system vulnerabilities.Īttack vectors include e-mail attachments, pop-up windows, viruses, deception, chat rooms, and instant messages. What is an attack vector? Common attack vectorsĪ vector attack is a path which cybercriminals use to access a computer or network server to execute a payload with the intention of a malicious outcome. One of the supposed hackers by the pseudonym Anton Lyashevesky told Information Security Media Group that the hackers infiltrated T-Mobile after the company’s misconfigured Gateway GPRS Support Node (GGSN) was exposed on the internet.Īccording to Lyashevesky, the criminals pivoted to the company’s LAN before proceeding to over one hundred Oracle databases containing the user data.įurther, a tweet handle the information was extracted from multiple T-Mobile data centers named Titan and Polaris.
The question is, How did hackers penetrate T-Mobile?Įven though the hackers’ identity remains shrouded in mystery, chats with the seller point to a vector attack. The records appeared for sale on a dark web forum, with the seller asking for 6 bitcoin (approximately $290,000 at the time of writing this).

According to Vice’s Motherboard magazine, the information includes Social Security Numbers, account pins, driver’s license numbers, names, and phone numbers.
The compromised data is as sensitive as it could get. Preliminary analysis revealed that the breach affected nearly eight million current postpaid customers and forty million former or prospective clients who had applied for credit with the company. “In addition, despite large breaches of personal data by all carriers over time these incidents do not appear to have led to more SIM jacking or identity theft incidents,”Broomhead said.Mobile carrier T-Mobile suffered a massive data breach recently, the 5th such occurrence in the last four years. “While there are state-level data breach disclosure laws in place, this timing barely meets most of them at 30 days and clearly does not meet the 10-day requirement in states like New York and Massachusetts.”īroomhead gives credit to T-Mobile, and other telecommunications companies that have been affected by cyber attacks, for being proactive in highlighting threats and deploying solutions for emerging cyber-attack vectors such as IoT and endpoint security. “Any delays in customer notification increases the risk and severity of individuals being exploited,” Broomhead said. “We expect to see organizations like T-Mobile provide more detailed analysis on the technical cause of the data breach - by providing a more detailed analysis, it would help the entire industry to take proactive steps to avoid similar issues,” Mandy said.īud Broomhead, CEO at Viakoo, said what he found most concerning is the time between the breach being detected (March 27) and when customers were notified (April 28). Mandy continued that it is also disappointing that details provided by T-Mobile on how the breach occurred and what data was actually impacted is still vague.
