Evdebir

We noticed a recent resurgence of interest in a 2018 data breach impacting Evdebir, a now defunct Turkish e-commerce platform. The initial discovery of this incident occurred when the compromised data began circulating on a prominent cybercrime forum. What struck us was the longevity of this particular dataset, resurfacing years after its initial compromise, suggesting its continued utility in credential stuffing attacks or for building more sophisticated threat profiles. The relatively small pwned count of 6030 records belies the potential impact of such a breach when combined with other, similarly compromised datasets.

The Evdebir breach, dating back to August 26, 2018, exposed 6030 unique user records. The core of the compromised information consists of email addresses and their corresponding password hashes, specifically MD5, which were also accompanied by their respective salts. This latter detail, the inclusion of salts, is crucial as it mitigates the effectiveness of pre-computed rainbow tables against the MD5 hashes, forcing attackers to perform individual cracking operations. The data was disseminated on a well-known cybercrime forum, indicating a deliberate attempt to monetize or weaponize the information. The breach type is categorized as a database compromise, with the resulting data likely contributing to or being utilized as a combolist for further malicious activities.

While this particular breach did not garner significant mainstream news coverage at the time, its reappearance on dark web forums is a recurring theme in cybersecurity. The longevity of such datasets underscores the persistent threat posed by credential stuffing and account takeovers. Researchers have repeatedly highlighted the dangers of using weak hashing algorithms like MD5, even with salting, as computational power continues to advance, making brute-force attacks increasingly feasible over time. The fact that this data is still being circulated and potentially utilized is a testament to the enduring value of compromised credentials in the underground economy.
