Insider Breach: T-Mobile Czech Employee Steals and Sells 1.5 Million Users Data

Jun 20, 2016
T-Mobile is the latest in the list of recent high-profile data breaches, though this time the breach is not carried out by "Peace" - the Russian hacker who was behind the massive breaches in some popular social media sites including LinkedIn , MySpace , Tumblr , and VK.com .

Yes, the customer service staff member tried to sell the T-Mobile customer marketing database, though it is not clear that how much of names, e-mail addresses, account numbers and other personal data of over 1.5 Million customers the database contained.

Top Cyber Attacks of 2020

Top Cyber Attacks of 2020

Jan 27, 2021
With so much of the world transitioning to working, shopping, studying, and streaming online during the coronavirus pandemic, cybercriminals now have access to a larger base of potential victims than ever before. "Zoombomb"  became the new photobomb—hackers would gain access to a private meeting or online class hosted on Zoom and shout  profanities and racial slurs  or flash  pornographic images . Nation-state hacker groups mounted attacks against organizations involved in the coronavirus pandemic response, including the World Health Organization and Centers for Disease Control and Prevention, some in an attempt to politicize the pandemic. Even garden-variety cyber attacks like email phishing, social engineering, and refund theft took on a darker flavor in response to the widespread economic precarity brought on by the pandemic.  "Hackers were mostly trying to take advantage of people's fear by offering medical equipment like thermometers and masks for cheap...
Virgin Media Data Leak Exposes Details of 900,000 Customers

Virgin Media Data Leak Exposes Details of 900,000 Customers

Mar 06, 2020
On the same day yesterday, when the US-based telecom giant T-Mobile admitted a data breach , the UK-based telecommunication provider Virgin Media announced that it has also suffered a data leak incident exposing the personal information of roughly 900,000 customers. What happened? Unlike the T-Mobile data breach that involved a sophisticated cyber attack, Virgin Media said the incident was neither a cyber attack nor the company's database was hacked. Rather the personal details of around 900,000 Virgin Media UK-based customers were exposed after one of its marketing databases was left unsecured on the Internet and accessible to anyone without requiring any authentication. "The precise situation is that information stored on one of our databases has been accessed without permission. The incident did not occur due to a hack, but as a result of the database being incorrectly configured," the company said in a note published on its website on Thursday night. Acc...
How Searchable Encryption Changes the Data Security Game

How Searchable Encryption Changes the Data Security Game

Jul 29, 2024 Data Security / Encryption
Searchable Encryption has long been a mystery. An oxymoron. An unattainable dream of cybersecurity professionals everywhere. Organizations know they must encrypt their most valuable, sensitive data to prevent data theft and breaches. They also understand that organizational data exists to be used. To be searched, viewed, and modified to keep businesses running. Unfortunately, our Network and Data Security Engineers were taught for decades that you just can't search or edit data while in an encrypted state. The best they could do was to wrap that plaintext, unencrypted data within a cocoon of complex hardware, software, policies, controls, and governance. And how has that worked to date? Just look at the T-Mobile breach, the United Healthcare breach, Uber, Verizon, Kaiser Foundation Health Plan, Bank of America, Prudential… and the list goes on. All the data that was stolen in those breaches remained unencrypted to support day-to-day operations. It's safe to conclude that the way we...
Reliance Jio Customers' Data Allegedly Hacked – Company Denies Breach

Reliance Jio Customers' Data Allegedly Hacked – Company Denies Breach

Jul 10, 2017
Personal details of some 120 Million customers have been allegedly exposed on the Internet in probably the biggest breach of personal data ever in India. Last night, an independent website named Magicapk.com went online, offering Reliance Jio customers to search for their identification data (Know Your Customer or KYC) just by typing in their Jio number. Reliance set up the Jio 4G network across the length and breadth of India in September last year and gained more than 50 million subscribers within a span of just 83 days. The company gave seven months of free internet, unlimited calls, unlimited music to its subscribers. Although the website that claimed to have hacked into Jio database is no longer accessible, many users confirmed their personal data showed up on the website, displaying their names, email addresses and most alarmingly, in some cases, Aadhaar numbers. Aadhaar is a 12-digit unique identification number issued by the Indian government to every resident of In...
New Survey Uncovers How Companies Are Confronting Data Security Challenges Head-On

New Survey Uncovers How Companies Are Confronting Data Security Challenges Head-On

Sep 27, 2023 Data Security / Cyber Attack
Data security is in the headlines often, and it's almost never for a positive reason. Major breaches, new ways to hack into an organization's supposedly secure data, and other threats make the news because well, it's scary — and expensive.  Data breaches, ransomware and malware attacks, and other cybercrime might be pricey to prevent, but they are even more costly when they occur, with the  average cost  of a data breach reaching $4.35 million and counting.  Accordingly, companies are investing in solutions that combat these problems and focusing on their Data security and protection more than ever, based on the results of the  WinZip Enterprise survey  of leading industry professionals responsible for implementing and maintaining security at their organizations.  Confidence is Up Among Data Security Pros While the media is reporting on a wide range of security threats, many of those surveyed reported a certain level of confidence in their organiz...

A subset of these records also contained one or more cell site identification numbers , potentially allowing the threat actors to triang...
