ZenBusiness Data Breach: 5.1M Records and SSNs Leaked

5.1 million ZenBusiness customer records hit a public data-breach index in mid-April. The dump reportedly includes names, emails, phones, and Social Security numbers from people who used the platform to form an LLC. ShinyHunters claimed responsibility on March 26th, demanded a ransom, and went public after non-payment. The group claims the data came out of three SaaS platforms ZenBusiness uses — Salesforce, Snowflake, and Mixpanel. Per Google's threat researchers, the group's documented technique against Salesforce isn't a software exploit but a vishing call: operators pose as IT and walk an employee through authorizing what looks like a routine connected app, then bulk-export the customer database. Whether that's how ZenBusiness was hit specifically, neither side has said. ZenBusiness has not, as of recording, publicly acknowledged the breach. Class-action attorneys are advertising for plaintiffs.
