PayPal is notifying nearly 35,000 users that their accounts had been compromised between December 6 and 8.
Although PayPal was not compromised, threat actors used credential stuffing to exploit previously leaked login information that people reused for their PayPal accounts.
According to PayPal, the credential stuffing attack took place between December 6 and December 8, 2022. The company detected and mitigated it immediately, but it also launched an internal investigation to determine how the hackers gained access to the accounts. PayPal completed its investigation by December 20, 2022, confirming that unauthorized third parties logged into the accounts using valid credentials.
PayPal claims that this was not the result of a system breach and that there is no evidence that the user credentials were obtained directly from them.
According to PayPal’s data breach reporting, the incident affected 34,942 of its users. Hackers gained access to account holders’ full names, dates of birth, postal addresses, social security numbers, and individual tax identification numbers over the course of two days.
PayPal accounts also provide access to transaction histories, linked credit or debit card information, and PayPal invoicing data.
