Now published through @CarnegieEndow – "Iran’s Cyber Threat: Espionage, Sabotage, and Revenge" – the decade long history of Iranian cyber operations against foreign and domestic targets. By me and @ksadjadpour.

Looks like internet access in Iran has been restored, at least to a basic degree for some providers.

Good lord, after two decades, is Iran's internet still: Broadband/National Networks <-> Telecommunication Infrastructure Company <-> Rest of the World, with most of the strangest dark arts and interference happening in AS49666?.

Missed that Lloyd Miller passed in December. Mormon missionary found his way to Iran, started a Jazz show as Kurosh Ali Khan, attempted to smuggle arms to resist the Russian invasion of Afghanistan. What a life. This Gol-e Gandom version is a banger.

Pretty sure this is the first time a company had ever been sanctioned after accidentally leaving an NFS server open to the public.

(Thread) Never going to be able to do anything with this, so here's a free research lead: in 2016, when sinkholing the Infy malware, I noticed an IP prefix would repeat beacons from Iran a few days after. Someone was parroting Iranian malware infected communications.

I’ll stop here for now. tldr; Iran was clearly ready for this moment to disconnect, but it was still surprisingly a scattershot/broken approach. But, it worked. I’ll also note that much of this has also been covered by the great folks: @OpenObservatory @gatech_ioda @DougMadory.

For everyone else, the VPN providers are essentially fighting a dozen fires. Each ISP is in their own unique way breaking some fundamental part of the internet (DNS, routing, TCP connectivity). And then, when you figure that out, the TCI will step in and cut everything off.

In Kurdistan or Sistan and Baluchestan, there's no options. Either residents need to find an office place with connectivity, but it's probable that those blackouts are more complete. And, Starlink is not going to get to either place anytime soon.

The net effect is that for those on Rightel during the curfew anti-filtering tools will not work. The only way out is to tunnel traffic through web hosting companies inside Iran, which is risky because hosting companies generally require national ID cards and bank accounts.

Another aside: blackouts are not uncommon in Iran now, see: But, I never knew that they seem to happen with a certain frequency in Sistan and Baluchestan.

Data from Iran's internet shutdown now posted. Interesting to see which government ministries and public institutions were disconnected (Health, universities), and which stayed online (Interior, Foreign Affairs, Parliament). . #IranProtests #KeepItOn
