Brinztech Alert: Unauthorized SQL Access to Repka.ua (Ukrainian E-Commerce) is on Sale

Dark Web News Analysis

A threat actor on a known cybercrime forum is advertising the sale of unauthorized SQL access to Repka.ua, a prominent Ukrainian e-commerce platform specializing in electronics and home goods. The access is being offered for a low price of $300.

Brinztech Analysis: This listing describes a classic Web Application Attack vector.

• The Vulnerability: The seller explicitly identifies the method as a Time-Based SQL Injection (SQLi). This is a technique where an attacker sends database queries that pause for a specific time (e.g., WAITFOR DELAY '0:0:5') if a condition is true. It allows them to slowly extract the entire database character by character.
• The Payload: The sale includes not just the vulnerability, but the “Full Database Dump” and “Admin Login Creds For Backend.” This suggests the attacker has already exploited the flaw to steal the data and compromise the administrative panel.
• The Data: The leak reportedly contains all customer data. While passwords are noted as “hashed,” the admin credentials allow for immediate site takeover.

This incident targets a Ukrainian business during a period of heightened cyber-physical conflict. However, the low price ($300) and the transactional nature of the post point to a financially motivated cybercriminal rather than a state-sponsored wiper attack.

Key Cybersecurity Insights

This alleged access sale presents a critical and immediate threat to the retailer and its customers:

• Critical Web Application Vulnerability (SQLi): The explicit mention of “Time-Based SQLi” highlights a fundamental coding error in Repka.ua’s web application. This type of vulnerability allows unauthorized users to bypass authentication and read the entire backend database.
• Backend Compromise Potential: The inclusion of “Admin Login Creds” means the buyer can do more than steal data; they can manipulate the store. Attackers could change product prices, reroute payments, or inject Magecart skimmers to steal credit cards from future customers.
• High Risk for Low Cost: The $300 price point makes this access accessible to even low-level threat actors (“script kiddies”). This increases the likelihood of the data being sold quickly and used for spam, phishing, or credential stuffing campaigns.
• Confirmed Data Breach: The seller’s claim of a “Full Database Dump” indicates that exfiltration has likely already occurred. The hashes, depending on the algorithm used (e.g., MD5 vs. bcrypt), may be easily cracked.

Mitigation Strategies

In response to this claim, Repka.ua and e-commerce administrators must take immediate action:

• Immediate Vulnerability Remediation (Patch SQLi): The IT team must urgently identify the vulnerable input fields (likely search bars, login forms, or product ID parameters) and sanitize them using Prepared Statements (Parameterized Queries).
• Enhanced Web Application Firewall (WAF): Deploy or tune a WAF to block common SQL injection patterns (like UNION SELECT, SLEEP, or BENCHMARK). A WAF can provide a “virtual patch” while the code is being fixed.
• Credential Reset: Immediately invalidate and reset all administrative and system credentials. Check the list of admin users for any unauthorized accounts created by the attacker.
• Customer Notification: If the database dump is confirmed, the company must notify customers to change their passwords, especially if they reuse them on other platforms.
