Sonicbids Data Breach (2019): What Was Exposed & What To Do

In December 2019, the online booking platform Sonicbids reported a data breach that exposed records belonging to 752,000 users. The company attributed the incident to a data privacy event involving its third-party cloud hosting services. The exposed information included names, usernames, email addresses, and passwords stored as PBKDF2 hashes. The dataset later reached breach notification services through breachbase.pw.

What happened

The breach was made public on December 30, 2019. Sonicbids stated that the incident stemmed from a data privacy event at a third-party cloud hosting provider. The compromised records numbered 752,000 and contained names and usernames, email addresses, and passwords stored using the PBKDF2 hashing algorithm. No further details on the timing of access, the method of intrusion, or the volume of data exfiltrated have been disclosed by the organization.

How a breach like this happens

Incidents involving third-party cloud hosting services often begin with the compromise of credentials, misconfigured access controls, or vulnerabilities in the provider’s infrastructure. Once an attacker obtains entry, they can extract stored user data without necessarily interacting directly with the customer organization’s own systems. In many such cases, the customer learns of the exposure only after the provider detects the activity or after the data later appears in public or semi-public repositories.

Sonicbids and its sector

Sonicbids operates an online marketplace that connects musicians and bands with promoters and venues for live performances. Platforms of this type maintain accounts for performers and bookers, storing contact details and authentication credentials to facilitate bookings and communications. A breach at such a service can affect individuals whose professional activities depend on the platform, as well as any personal or business email addresses they used for registration.

What data was at risk

The records confirmed as exposed contained names, usernames, email addresses, and passwords stored as PBKDF2 hashes. The exact scope of additional fields, if any, remains undisclosed. Organizations in the live-events sector commonly hold further details such as phone numbers, location information, and payment or billing data, but no confirmation exists that such information was included in this incident.

The real-world impact

Exposed email addresses and usernames can be used for targeted phishing or account takeover attempts on other services where the same credentials may have been reused. Passwords protected by PBKDF2 hashing present a higher barrier to recovery than unsalted or weakly hashed values, yet offline attacks remain possible if the hashes are obtained. For the organization, the incident creates notification obligations and potential loss of user trust, though the scale of any resulting fraud or account abuse has not been publicly quantified.

If your data was in this breach

Individuals can change passwords on Sonicbids and any other sites where the same credentials were used. Enabling multi-factor authentication where available reduces the value of a leaked password. Monitoring email accounts for unusual login attempts or unsolicited messages provides an early indicator of misuse. Readers may also run a free exposure scan of their email address against known breach data to determine whether their information appears in this or other incidents.
