Anecdotes, news reports, and policy briefings collectively suggest that Internet censorship
practices are pervasive. The scale and diversity of Internet censorship practices makes it …

In this paper, we report a subtle yet serious side channel vulnerability (CVE-2016-5696)
introduced in a recent TCP specification. The specification is faithfully implemented in Linux …

Protecting network protocols within an encrypted tunnel, using technologies such as Virtual
Private Networks (VPNs), is increasingly important to millions of users needing solutions to …

In this study, we discover a subtle yet serious timing side channel that exists in all
generations of half-duplex IEEE 802.11 or Wi-Fi technology. Previous TCP injection attacks …

Cyber Security can be thought of as a set of techniques used to protect the secrecy, integrity,
and availability of computer data against threats. Scanning attack itself is not a technique; In …

We present a novel attack for detecting the presence of an active TCP connection between a
remote Linux server and an arbitrary client machine. The attack takes advantage of side …

In this paper, we report a subtle yet serious side channel vulnerability (CVE-2016-5696)
introduced in a recent transmission control protocol (TCP) specification. The specification is …

Recent work has showcased the presence of subtle TCP side channels in modern operating
systems, that can be exploited by off-path adversaries to launch pernicious attacks such as …

Active Internet measurements face challenges when some measurements require many
remote vantage points. In this paper, we propose a novel technique for measuring remote …

We present ONIS, a new scanning technique that can perform network measurements such
as: inferring TCP/IP-based trust relationships off-path, stealthily port scanning a target …
