I have much criticism about the Israeli government information security status and activity. Lots of PR and marketing for being a “Cyber Nation” but it is true mostly for the selling of knowledge, services and products. Not so much doing the “dirty work” of protecting the Israeli Internet facing IT, including the one of the Israel government itself.
So, I started this weekend to operate a mini-project of checking the quality of HTTPS sites of the gov.il sub-domains. I publish the results in a public spreadsheet, accessible as read-only (viewing, downloading and printing is allowed anonymously) from Google – https://docs.google.com/spreadsheets/d/1Fez2A1FwqesWRuc2DowpdG20okh-KDbYfO5qnl8nZ-U/edit?usp=sharing
While running these checks I found something alarming:
One of gov.il’s DNS servers, a server called dns3.gov.il, at 62.219.20.20 – replied at port 22 TCP, i.e. SSH, a service used to manage mostly Unix/Linux servers. Yes, open, allowing me try to login…
As I found it, in the afternoon of Friday, 31-Jan-20, I sent this finding at 16:28 to the Israeli national CERT and after ten minutes I also managed to correspond with someone I am in contact with, who was senior in government’s information security department, and he forwarded this issue to another security senior in the government’s IT, and he passed the details on to those who can fix this issue.
It took a few hours, but at the last check I did, around 21:30 that evening – access was blocked as this port has been closed, so it seemed to me that the issue had been addressed. Quite fast for almost Friday evening (the beginning of Shabbat in Israel).
Another point was that the SSH server identification was SSH-2.0-OpenSSH_7.4p1 Debian-10 + deb9u6, which means that the OpenSSH version is 7.4p1 that was released in December 2016, and since then several versions and a few security fixes for various security issues were released for OpenSSH, which are probably missing now from server. I hope they will update what is needed as soon as possible.
