OONI measurements showed [] messaging apps are being blocked via RST packet injection during the TLS handshake. The same technique can be used to stop VPN connections, as was observed to block VPNs during the Telegram disruptions in Oct + Nov 2020. (2/6)
🔴Today OONI data shows that
#Cuba
started blocking WhatsApp, Telegram & Signal amid protests.
Blocking appears to be happening by injecting a TCP RST packet during the TLS handshake.

The repressive Cuban government is attempting to squash protests by cutting off internet access. Yet, over 146,000 Cubans continue to have daily access to the internet thanks to open-source tools supported by the bipartisan Open Technology Fund my colleagues and I championed.
