The threat intel team at Recorded Future, a US-based cyber-security firm, claims to have identified the hacker who assembled and then sold a massive collection of email addresses and passwords known as Collection #1.
The company’s experts believe a hacker going online by the pseudonym of “C0rpz” is the person who rigorously and meticulously collected billions of user records over the past three years. This includes records from companies that were hacked in the past and whose data was posted or sold online.
Recorded Future says that C0rpz isn’t only responsible for assembling and selling Collection #1, a data trove of 773 million unique email addresses and just under 22 million unique passwords that grabbed headlines at the start of the year, but many more other data collections.
Researchers say Collection #1 was part of a larger package containing seven other “collections” in total.
- “ANTIPUBLIC #1” (102.04 GB)
- “AP MYR & ZABUGOR #2” (19.49 GB)
- “Collection #1” (87.18 GB)
- “Collection #2” (528.50 GB)
- “Collection #3” (37.18 GB)
- “Collection #4” (178.58 GB)
- “Collection #5” (40.56 GB)
Of the seven, the AntiPublic collection had already leaked online and had been shared among other hackers since April 2017. The rest appear to be new items, that hadn’t been seen online until this month.
In total, these databases appear to contain more than 3.5 billion user records, in combinations such as email addresses and passwords, usernames and passwords, and cell phone numbers and passwords.
Recorded Future says C0rpz sold this data to other hackers, who are now disseminating it for free via online sharing portal MEGA and via torrent magnet links.
Some of the hackers who bought this data from C0rpz are Sanix, another hacker who infosec journalist Brian Krebs first identified as the source of Collection #1, and Clorox, the person who initially shared Collection #1 for free on Raid Forums at the start of the month, inadvertently exposing this huge data trove to security researchers and journalists.
“Neither of three actors has ever been on our radar,” Andrei Barysevich, Director of Advanced Collection at Recorded Future, told ZDNet in an email today. “However, we did find a previous online footprint on all actors, which does not suggest that these actors are sophisticated.”
Barysevich also told ZDNet that his team didn’t find “any proof” that the named three, including C0rpz, are hackers, responsible for actual breaches at any company.
“We believe they have merely aggregated the data over the time,” Barysevich told us.
But Recorded Future experts aren’t 100 percent sure in their attribution of these data collections to C0rpz –as no attribution that involves self-aggrandizing and braggadocio hackers can truly ever be 100 percent. Experts are also looking into another possible source of the leak, which they did not name yet.
“On January 10, 2019, an actor on a well-known Russian-speaking hacker forum posted both a magnet link and a direct download link to a database containing 100 billion user accounts hosted on a personal website,” Recorded Future said in a report published earlier today. “The following week, the actor made clear that the data dump referenced in Troy Hunt’s [Collection #1] article was included in their dump as well.”
To be fair, it doesn’t really matter who assembled, sold, or shared this data in the end. All this data was previously available for years. The difference was that in past, this data was shared in individual packages, per site of origin.
It’s only become a recent trend for data hoarders (hackers who collected data from hacked sites) to assemble these smaller leaks and breaches into gigantic packages.
This became a trend because more and more companies are getting hacked, and the value of individual leaks became smaller. Data sellers adapted and started merging leaks together to continue to make a profit.
There are likely hundreds of similar mega-packages being shared on hacking forums out of the public eye as we speak, which have not made the light of day yet.
Eventually, they will. When that happens, cyber-crime groups will collect these aggregated leaks, extract any new user records they don’t have, and use this information to spam our email inboxes, attempt brute-force attacks against our online accounts, or, even worse, use these details for extortion or financial fraud.
It is highly likely that most of our data has already leaked online by now. All, we, the users, can do is protect our accounts with strong passwords that are unique per site, enable multi-factor authentication wherever possible, and avoid entrusting our data to any company that asks for our details for no good reason.
Now, if we could only get journalists to stop blowing these “collections” out of proportion every time one of them surfaces online.

Key Criteria for Evaluating Unified Endpoint Management
Endpoint management is one of the most significant challenges in the enterprise today. An increasingly large percentage of our workforce is distributed and demands flexibility to work wherever they want, whenever they want. We must respond by giving them access to the services they require to do their jobs effectively. The alternative is that we, as a business, will suffer, lose good people, and become less competitive. However, we must achieve this essential access while maintaining security and control of our business’s data assets.
An appropriate endpoint management strategy is key to addressing these issues. Our approach should be holistic and unified, bringing together control of devices, management of applications, security of data, and access controls.
Unified endpoint management (UEM) is the approach to meeting this challenge. It has evolved from traditionally disparate solutions for endpoint management, application delivery, and security into a single platform. This single platform delivers a consistent end-user experience across all devices, applications, and locations while maintaining security and control of data assets. The leading solutions allow us to enroll devices easily into our control, provide support, and ensure constituency and compliance while managing access to our applications and data.
This GigaOM Key Criteria Report describes UEM solutions and identifies key criteria and evaluation metrics for selecting such a solution. The corresponding GigaOm Radar Report identifies vendors and products that excel in this sector. Together, these reports give decision-makers an overview of the market to help them evaluate existing platforms and decide where to invest.

The file and cloud experts will discuss the limitations of traditional NAS architectures in today’s corporate environments and how organizations are implementing distributed cloud file storage to solve remote collaboration, ransomware protection, and unstructured data growth challenges.
Signoretti and Brand will also examine the recently published GigaOm Radar for Distributed Cloud File Storage, in which CTERA was named the leader. They will review the report’s key criteria and evaluation metrics for choosing a distributed cloud file storage platform, helping IT leaders to understand which vendors are most aligned to their needs today as well as 12-18 months down the road.

High Performance Application Security Testing – Cloud WAF Security Platforms
This free 1-hour webinar from GigaOm Research features analyst Jake Dolezal and will focus on comparing Web Application Firewall (WAF) security platforms in an enterprise with high performance needs.
This webinar will discuss web application security mechanisms deployed in the cloud. The cloud enables enterprises to differentiate and innovate with microservices at a rapid pace. However, the cloud is just as vulnerable, if not more so, to attacks and breaches as on-premises APIs and apps are. Our focus is specifically on approaches to securing apps, APIs, and microservices that are tuned for high performance and availability. We define “high performance” as companies that experience workloads of more than 1,000 transactions per second (tps) and require a maximum latency below 30 milliseconds across the landscape.
In this webinar, we will reveal the performance tests of security mechanisms on NGINX, AWS, and Azure, specifically: ModSecurity, NGINX App Protect WAF, AWS Web Application Firewall (WAF), and Azure WAF.
Register now to join GigaOm and NGINX for this free expert webinar.
