Megaleak of 2.2 Billion Records Found in the Wild

Hackers have compiled a voluminous collection of more than 2.2 billion unique usernames and passwords that is now being distributed freely online. The database, dubbed “Collection 2-5”, weighs in at a whopping 845 gigabytes and contains more than 25 billion records in total. Speaking to Wired, Chris Rouland, a cybersecurity researcher, said, “This is the biggest collection of breaches we’ve ever seen.” While many of the stolen credentials appear to have come from previous breaches, the size of the collection is unprecedented and will more than likely lead to a surge in account takeover attempts.

Facebook’s Surveillance App Banned from App Store

Facebook is facing scrutiny for its data practices yet again. As reported by TechCrunch, Facebook paid users between the ages of 13 to 35 to install a Facebook Research VPN, codenamed Project Atlas, that tracked and siphoned up all of their phone and network activity for a mere $20 per month.

59,430 Data Breaches Disclosed Under GDPR

Since the EU’s General Data Protection Regulation went into effect in May 2018 there have been over 59,000 data breaches reported to European data regulators. Countries with the most breaches include the Netherlands (15,400), Germany (12,600), and the UK (10,600). When ranked by breaches per capita, Netherlands comes out on top with 89.8 breaches per 100,000 population, followed closely by Ireland (79.4) and Denmark (53.3). Of the 59,430 disclosed breaches, fines were levied in only 91 of the cases, with the largest coming in January when French data protection watchdog CNIL imposed a $56.8 million fine on Google for violating GDPR consent provisions. As regulators make their way through a backlog of GDPR breach notifications, analysts believe billion Euro fines could be on the horizon.

Discover Card Accounts Compromised

Discover notified California’s Attorney General that a data breach in August of last year compromised an unknown number of Discover card accounts, with hackers having potentially stolen credit card numbers, security codes, and personally identifiable information.
