In recent years, malware is increasingly applying means of hidden communication. The emergence of network-capable stegomalware applies such methods to communication networks. In this paper, we introduce and evaluate two covert channels that utilize reconnections to transmit hidden information in WiFi networks. We implement these covert channels in the 802.11 protocol by abusing the authentication mechanism of these networks. Furthermore, we propose detection methods and countermeasures for bo...In recent years, malware is increasingly applying means of hidden communication.

We implement these covert channels in the 802.11 protocol by abusing the authentication mechanism of these networks. Furthermore, we propose detection methods and countermeasures for both covert channels. Our implementation and quick-start guide are available as open source code on GitHub to aid replicability.» weiterlesen » einklappen
