As a result of the Russian invasion of Ukraine, several certificate authorities, like DigiCert and Sectigo, have revoked certificates of Russian entities or are refusing to issue new certificates for them. In response, Russian government authorities have created their own certificate authority.
Users in Russia are advised to either install the new root certificate in their browser or use one of the Russian-based Yandex and Atom browsers.
Unsurprisingly the operation of a state CA outside the normal web PKI system raises concerns. The root certificate could be used to perform man-in-the-middle attacks against users that have installed it. A previous case in which the country of Kazakhstan asked its users to install a root CA, which we have covered in this newsletter before, has been mentioned often.
Yandex has put up a blog post with more details (the post is in the Russian language; here’s a version translated with Google Translate). Notably, Yandex claims that its browser will only accept certificates issued by the new CA if they are in a list of domains actually approved for the use of this CA. This may limit the potential security impact of man-in-the-middle attacks. Yandex also mentions that it plans to operate a Certificate Transparency log for this new CA.
This subscription is just for the newsletter; we won't send you anything else.
Here are some interesting jobs we've come across in the last month:
If you know of similar jobs that our readers might be interested in, for example cryptography, TLS, or PKI, let us know and we may add them to future newsletters.
Designed by Ivan Ristić, the author of SSL Labs, Bulletproof TLS and PKI, and Hardenize, our course covers everything you need to know to deploy secure servers and encrypted web applications.
Remote and trainer-led, with small classes and a choice of timezones.
