Hackers claimed to be selling a dataset of **15.8 million PayPal credentials**, including login emails, plaintext passwords, and associated URLs, allegedly stolen in May 2025. The leaked data was advertised for automated credential stuffing and identity theft attacks. However, experts questioned its authenticity due to the **small sample size provided for verification**, the **suspiciously low pricing** (unusual for high-value stolen data), and its resemblance to **infostealer malware logs** from past incidents rather than a direct breach of PayPal’s systems.PayPal denied any new breach, attributing the claims to a **2022 security incident** involving credential stuffing that exposed only **35,000 accounts**—far fewer than the current claim. The incident highlights risks from **reused credentials**, as compromised logins from infected user devices (not PayPal’s servers) could still enable fraud. While the legitimacy of the 2025 dataset remains unconfirmed, the scenario underscores persistent threats from **stolen credentials circulating on dark web marketplaces**, enabling long-term identity theft and financial fraud risks for users who reuse passwords across platforms.
