T-Mobile Data Breach: T-Mobile has suffered another data breach, this time affecting around 37 million postpaid and prepaid customers who've all had their data accessed by hackers. The company claims that while it only discovered the issue on January 5th of this year, the intruders are thought to have been exfiltrating data from the company's systems since late November 2022.
As discussed in the introduction to this article, this is not the first time that T-Mobile has fallen victim to a high-profile cyber attack impacting millions of customers. In the aftermath of last year's attack, during which 76 million customers had their data compromised, the company pledged it would spend $150 million to upgrade its data security – but the recent attack raises serious questions over whether this has been well spent.
PayPal Data Breach: A letter sent to PayPal customers on January 18, 2023, says that on December 20, 2022, “unauthorized parties” were able to access PayPal customer accounts using stolen login credentials.
PayPal goes on to say that the company has “no information” regarding the misuse of this personal information or “any unauthorized transactions” on customer accounts and that there isn't any evidence that the customer credentials were stolen from PayPal's systems.
Chick-fil-A Data Breach: fast food chain Chick-fil-A is investigating “suspicious activity” linked to a select number of customer accounts.

Twitter Data Breach: Twitter users' data was continuously bought and sold on the dark web during 2022, and it seems 2023 is going to be no different. According to recent reports, a bank of email addresses belonging to around 200 million Twitter users is being sold on the dark web right now for as little as $2. Even though the flaw that led to this leak was fixed in January 2022, the data is still being leaked by various threat actors.
Slack Security Incident: Business communications platform Slack released a statement just before the new year regarding “suspicious activity” taking place on the company's GitHub account.
“Upon investigation, we discovered that a limited number of Slack employee tokens were stolen and misused to gain access to our externally hosted GitHub repository. Our investigation also revealed that the threat actor downloaded private code repositories on December 27,” the company said. However, Slack confirmed that “no downloaded repositories contained customer data, means to access customer data, or Slack’s primary codebase”.
SevenRooms Data Breach: Threat actors on a hacking forum posted details of over 400GB of sensitive data stolen from the CRM platform's servers. The information included files from big restaurant clients, promo codes, payment reports, and API keys. However, it seems that the servers that were breached did not store any customer payment details.
LastPass Data Breach: Password manager LastPass has told some customers that their information was accessed during a recent security breach. According to LastPass, however, no passwords were accessed by the intruder. This is not the first time LastPass has fallen victim to a breach of their systems this year – someone broke into their development environment in August, but again, no passwords were accessed.
AirAsia Data Breach: AirAsia Group has, according to reports, suffered a ransomware attack orchestrated by “Daixin Team”. The threat group told DataBreaches.net that they obtained “the personal data of 5 million unique passengers and all employees.” This included name, date of birth, country of birth, location, and their “secret question” answer.
Dropbox data breach: Dropbox has fallen victim to a phishing attack, with 130 Github repositories copied and API credentials stolen after credentials were unwittingly handed over to the threat actor via a fake CricleCI login page.
However, Dropbox confirmed in a statement relating to the attack that “no one's content, passwords or payment information was accessed” and that the issue was “quickly resolved”. Dropbox also said that they were in the process of adopting the “more phishing-resistant form” of multi-factor authentication technique, called “WebAuthn”.
Medibank Data Breach: Medibank Private Ltd, currently the largest health insurance provider in Australia, said today that data pertaining to almost all of its customer base (nearly 4 million Australians) had been accessed by an unauthorized party.

Toyota Data Breach: In a message posted on the company's website, the car manufacturer stated that almost 300,000 customers who had used its T-Connect telematics service had had their email addresses and customer control numbers compromised.

Optus Data Breach: Australian telecoms company Optus – which has 9.7 million subscribers – has suffered a “massive” data breach. According to reports, names, dates of birth, phone numbers, and email addresses may have been exposed, while a group of customers may have also had their physical addresses and documents like driving licenses and passport numbers accessed.
The attackers are thought to be a state-sponsored hacking group or some sort of criminal organization and breached the company's firewall to get to the sensitive information. Australia's Information Commissioner has been notified.
The Australian government has said Optus should pay for new passports for those who entrusted Optus with their data, and Prime Minister Antony Albanese has already suggested it may lead to “better national laws, after a decade of inaction, to manage the immense amount of data collected by companies about Australians – and clear consequences for when they do not manage it well.”
American Airlines Data Breach: The personal data of a “very small number” of American Airlines customers has been accessed by hackers after they broke into employee email accounts, the airline has said. Information accessed could have included customers' date of birth, driver's license, passport numbers, and even medical information, they added.

Rockstar Data Breach: Games company Rockstar, the developer responsible for the Grand Theft Auto series, was victim of a hack which saw footage of its unreleased Grand Theft Auto VI game leaked by the hacker. In addition, the hacker also claims to have the game's source code, and is purportedly trying to sell it. The breach is thought to have been caused through social engineering, with the hacker gaining access to an employee's Slack account. The hacker also claims to be responsible for the Uber attack earlier in the month.
In a statement, Rockstar said: “We recently suffered a network intrusion in which an unauthorized third party illegally accessed and downloaded confidential information from our systems, including early development footage for the next Grand Theft Auto.”

TikTok Data Breach Rumour: Rumours started circulating that TikTok had been breached after a Twitter user claimed to have stolen the social media site's internal backend source code. However, after inspecting the code, a number of security experts have dubbed the evidence “inconclusive”, including haveibeenpwned.com's Troy Hunt. Users commenting on YCombinator's Hacker News, on the other hand, suggested the data is from some sort of ecommerce application that integrates with TikTok.
Responding to a request for comment from Bloomberg UK, a spokesperson for TikTok said that the company's “security team investigated this statement and determined that the code in question is completely unrelated to TikTok’s backend source code.”
Samsung Data Breach: Samsung announced that they'd fallen victim to a “cybersecurity incident” when an unauthorized party gained access to their systems in July.

Uber Data Breach Cover-Up: Although this data breach actually took place way back in 2016 and was first revealed in November 2017, it took Uber until July 2022 to finally admit it had covered up an enormous data breach that impacted 57 million users, and even paid $100,000 to the hackers just to ensure it wasn't made public. The case will see Uber's former chief security officer, Joe Sullivan, stand trial for the breach – the first instance of an executive being brought to the dock for charges related to a data breach.
Twitter Data Breach: The first reports that Twitter had suffered a data breach concerning phone numbers and email addresses attached to 5.4 million accounts started to hit the headlines on this date, with the company confirming in August that the breach was indeed genuine. The vulnerability that facilitated the breach was known by Twitter at the turn of the year and had been patched by January 13, 2022, so data theft must have happened within that short window.
Neopets Data Breach: On this date, a hacker going by the alias “TarTaX” put the source code and database for the popular game Neopet’s website up for sale on an online forum.

Data Breaches vs Data Leaks vs Cyberattacks
This article largely concerns data breaches. A data breach occurs when a threat actor breaks into (or breaches) a company, organization, or entity’s system and purposefully lifts sensitive, private, and/or personally identifiable data from that system. When this happened, companies are sometimes forced to pay ransoms, or their information is stolen ad posted online. According to one estimate, 5.9 billion accounts were targeted in data breaches last year.
This is different from a data leak, which is when sensitive data is unknowingly exposed to the public/members of the public, such as the Texas Department for Insurance leak mentioned above. The term “data leak” is often used to describe data that could, in theory, have been accessed by people it shouldn't of, or data that fell into the hands of people via non-malicious means. A government employee accidentally sending someone an email with sensitive data is usually described as a leak, rather than a breach.
Although all data breaches fall under the umbrella of a “cyber attack“, cyber attacks are not limited to data breaches. Some cyber attacks have different motivations – such as slowing a website or service down or causing some other sort of other disruption. Not all cyberattacks lead to the exfiltration of data, but many do.
