Worth noting: the warning originally had a direct mention that the attack was from a surveilling government, but they removed that part after being asked.
Quoting the government portion
Apple declined to elaborate on the specific spyware attack since doing so could tip off the attackers about the company’s detection techniques. Still, the email references commercial surveillance provider NSO Group, an Israeli company notorious for developing the Pegasus spyware, which can sometimes hijack a smartphone simply by sending the user a single message. In the past, Pegasus has been found on phones belonging to activists, journalists, and politicians, with additional evidence pointing to governments possibly buying access to the spyware tech.
These spyware attacks can cost millions of dollars to develop. They can then expire once the software vulnerabilities they exploit are patched. As a result, commercial spyware providers and their government customers tend to deploy such attacks in a targeted fashion, rather than through mass deployment. Still, Apple’s alert underscores how pervasive commercial spyware has become, targeting users in nearly half of the world’s countries.
What was the surveiling government? I did a quick search on the article and didn't see it mentioned
It was never mentioned by name, only being referred to by apple as "being state-sponsored". They also do openly mention Israel in connection with NSO Pegasus though.
Darn it. From the way it was phrased -- or maybe how I misread it -- I thought the implication was that the government was initially named in the article
