Pincode Search & Find

We noticed a concerning aggregation of credentials surfacing on a well-established underground forum, dated August 21, 2018. The dataset, totaling 16,437 unique entries, appears to originate from the now-defunct Indian information portal, Pincode Search & Find. What struck us immediately was the inclusion of plaintext passwords alongside email addresses, a significant vulnerability that amplifies the risk of credential stuffing attacks against other services. The relatively small size of the dataset, when compared to larger, more recent breaches, might suggest it's an older, but still potent, source of compromised credentials.

The breach breakdown reveals a straightforward database exfiltration, likely facilitated by a vulnerability within the Pincode Search & Find infrastructure. The exposed data primarily consists of email addresses and their corresponding plaintext passwords. This combination is a goldmine for threat actors, enabling them to attempt logins on numerous other platforms where users commonly reuse credentials. The source structure indicates a direct dump from a user account database, and the leak location was a prominent hacking forum, suggesting an intent to distribute or monetize the compromised information. The fact that the website is defunct does not diminish the threat; these credentials remain highly valuable for opportunistic attacks.

While this specific incident from 2018 did not generate widespread mainstream news coverage at the time, the practice of selling credential dumps on hacking forums is a persistent and well-documented threat. Open-source intelligence (OSINT) consistently highlights the ongoing trade of such datasets, often aggregated and resold multiple times. Research from various cybersecurity firms, such as those focusing on credential stuffing and identity theft, frequently references the enduring impact of older, but still potent, data breaches. The exposure of plaintext passwords, even from a defunct service, contributes to the broader landscape of compromised credentials that fuel cybercrime.
