Following the initial dataset, a larger set of records was released, reaching a total impact of 103,077 unique email addresses. The supported data classes are email addresses, names, and usernames. The password field is not listed in this record. Due to the educational and coding practice context, the incident is still significant, as students, instructors, and prospective developers may reuse the same identity across different educational, school, and technical platforms.\u003C\u002Fp>\u003Ch2>Leaked Data Types and Risks\u003C\u002Fh2>\u003Cp>The CodeStepByStep record includes email address, name, and username. Since these fields do not directly contain a password, the risk of account takeover is more limited compared to password leaks. However, the educational ID, school affiliation, or coding username could be matched with different platforms. Attackers may send targeted messages using themes such as fake course notifications, assignment alerts, account closure messages, certificate offers, or developer community invitations. Passwords, phone numbers, addresses, grades, payment information, or source file contents are not listed under this record, so they have not been included.\u003C\u002Fp>\u003Ch2>Verified Scope and Boundaries\u003C\u002Fh2>\u003Cp>The record is kept in a verified status, and the existence of the incident is also supported by the platform's own statements. However, data classes are limited. Since there is a difference in numbers between the initially announced record set and the larger data group published later, the updated total impact has been used in this record. Since there is no password field, it is not described as if the user's password has been leaked. The incident should be considered as a risk of matching educational ID and email. It should not be assumed that every user is affected in the same detail or that course content has been leaked.\u003C\u002Fp>\u003Ch2>User Groups at Risk\u003C\u002Fh2>\u003Cp>Students, instructors, computer science course participants, and people who use the same username on Git-based platforms, technical forums, or school systems are at risk. The combination of name and email makes fake educational messages more convincing. If the username is the same as technical profiles, attackers can correlate accounts on different platforms. Users registered with a school or course email should be cautious of assignment, grade, or access messages that appear to be sent on behalf of the institution.\u003C\u002Fp>\u003Ch2>Urgent Measures to Be Taken\u003C\u002Fh2>\u003Cp>Users with a CodeStepByStep match should check their account security settings and review privacy settings on technical platforms where they use the same username. Since the password field is not listed, mandatory password panic is not necessary; however, if the password used for the same service is weak or reused elsewhere, it should be changed. Emails related to education, assignments, exams, certificates, or account access should not be opened directly from the link but should be verified through the known domain. If a school account is being used, the institution's security guidelines should be followed.\u003C\u002Fp>\u003Ch2>Long-Term Security Strategies\u003C\u002Fh2>\u003Cp>Using the same username, email, and real name everywhere on educational and coding platforms increases the risk of profile matching. Users should keep their personal, school, and developer accounts as separate as possible. A unique password should be used for each platform, and two-factor authentication should be enabled on technical accounts. Students should regularly check profiles on old course platforms and close accounts that are no longer used. Instructors should use only official channels for class lists and student communications.\u003C\u002Fp>\u003Ch2>Record Control and User Action\u003C\u002Fh2>\u003Cp>If there is a match in CodeStepByStep during LeakData monitoring, the user should consider this as a warning regarding the visibility of their education ID and email. The match does not indicate a password or payment data leak. The first step is to check whether the same username is used on other technical platforms. The second step is to develop a habit of verification against education-themed phishing messages. The third step is to make two-factor authentication and the use of unique passwords permanent on school or developer accounts.\u003C\u002Fp>","CodeStepByStep Data Breach (103.1 Thousand Reported Records)","CodeStepByStep Data Breach. 103.1 Thousand reported records are reported.
