Then obtain system info, start a key logger and continue exploiting the network. repository metadata shall be laid out in this section. Unlike the tens of BlueKeep proof-of-concept exploits that have been uploaded on GitHub over the past months, this module can achieve code execution.

In sections 3.2 and 3.3 we presented actual measuremen, ing our claim that the attack described in this paper is indeed dangerous to a certain. only provide rather rough estimates based on existing research. As a consequence and main conclusion of this paper, we suggest multiple preventive measures that should be implemented as soon as possible.

GitHub API as defined in its documentation. Because the attacker has enough information about the person (real name, contributed, repositories, favored programming languages), the person may actually be tricked into. . instead of the primary email address provided by the user. When those commits are pushed to remote hosting services like GitHub, those email addresses become visible not only to fellow developers, but also to malicious actors aiming to exploit them. In contrast to other countermeasures, this feature doesn’t aim to defend the collec-, tion of data in the first place, but rather prevent accoun, malicious actor already achieved to collect user creden, In this chapter we describe the attack: Using public GitHub rep, analyze it to get detailed information about real persons and finally exploit it on a large, measurements resulting from an actual implementation of the first part of this attac, The following sections will address the respective methods and procedures of the three, GitHub Search API. cloning huge amounts of repositories and therefore significantly mitigate their effect.
