Time Warner Cable Business Class

We've seen a recent resurgence of older breaches surfacing in aggregated credential stuffing lists, likely due to the increasing sophistication of botnets and their ability to test vast combinations of usernames and passwords. What caught our attention with this particular resurfaced breach wasn't its size, but the continued relevance of the targeted organization: Time Warner Cable Business Class. The data, dating back to February 2015, contains credentials that, if still valid, could provide access to sensitive business accounts and infrastructure. This highlights the long tail of risk associated with breaches, even those nearly a decade old.

Time Warner Cable Business Class data from 2015 surfaces in credential stuffing lists

A database breach impacting 3,174 users of Time Warner Cable Business Class has recently resurfaced on several credential stuffing lists. While the breach itself occurred on February 28, 2015, its reappearance underscores the enduring risk posed by exposed credentials. The data includes a mix of information that can be highly valuable to attackers: email addresses, usernames, and hashed passwords. The passwords themselves are of particular concern, as even if hashed, weak or commonly used passwords can be cracked relatively easily, especially with modern cracking tools. The breach's reappearance now matters to enterprises because the exposed credentials could still be valid for some users, granting unauthorized access to Time Warner Cable Business Class accounts. This risk is amplified if users have reused these credentials across multiple platforms, a common practice that expands the potential impact of a single breach.

• Total records exposed: 3,174
• Types of data included: Email addresses, usernames, hashed passwords
• Sensitive content types: Account credentials
• Source structure: Database
• Leak location(s): Credential stuffing lists
• Date of first appearance: February 28, 2015

The re-emergence of this Time Warner Cable Business Class data aligns with a broader trend of older breaches being weaponized in automated attacks. As noted by security researcher Troy Hunt, large collections of breached credentials are often compiled and sold on the dark web, forming the basis of credential stuffing attacks. These lists are constantly updated and refined, making even older breaches a persistent threat. The fact that this breach is now circulating again suggests that attackers are actively targeting Time Warner Cable Business Class accounts, or at least including them in their broad sweeps of potential targets.
