Tech industry quietly patches FragAttacks Wi-Fi flaws that leak data, weaken security

The dozen vulnerabilities affect all Wi-Fi security protocols since the wireless networking technology debuted in 1997, from WEP up through WPA3.
One design flaw is in the frame aggregation functionality, and another two are in the frame fragmentation functionality, explains Vanhoef in his paper. These design flaws enable an adversary to forge encrypted frames in various ways, which in turn enables exfiltration of sensitive data.
He also identified flaws in the way frame aggregation – combining multiple network data frames – and frame fragmentation – splitting network data frames into smaller pieces – are implemented that magnify the impact of potential attacks.
The 802.11 frame aggregation flaw involves flipping an unauthenticated flag in a frame header, which allows the encrypted data payload to get parsed as if it were multiple aggregated frames instead of a simple network packet. ....

Domain Shadowing: Leveraging CDNs for Robust Blocking-Resistant Communications

by mingkui | April 22, 2021
We invited guest blog author, Mingkui Wei, to submit a summary of their research to the blog this week. This blog post is based on the upcoming Usenix Security paper (full version here). Note that the domain shadowing ideas presented herein are intended to be a building block for a future system that doesn t exist for end-users yet. We hope this post will help system designers to think in new ways, and use those ideas to build new censorship circumvention tools.
What is Domain Shadowing?
Domain shadowing is a new censorship circumvention technique that uses Content Distribution Networks (CDNs) as its leverage to achieve its goal, which is similar to domain fronting. However, domain shadowing works completely differently from domain fronting and is stronger in terms of blocking-resistance. Compared to domain fronting, one big difference among many is that the user in domain shadowing is in charge of the whole procedure. In other words ....
