I also use Ollama for coding. I have a 32G M2 Mac, and the models I can run are very useful for coding and debugging, as well as data munging, etc. That said, sometimes I also use Claude Sonnet 3.5 and o1. (BTW, I just published an Ollama book yesterday, so I am a little biassed towards local models.)
The flip side is companies that are not active participants in the open source community (but know they use open source), are pinging all their engineering managers and asking "are we exposed to this!? how do you know!?".
So while it's useless noise to you, it's likely triggered by being on the receiving end of communications like "Hey, my boss is asking if $PROJECT is vulnerable because of a terrible article he read in $MAINSTREAM_MEDIA_PROPERTY?" times however many bosses are harassing their reports.
"I don't want to craft an email reply to every single person, just put up the no-op blog post and be done with it."
I've generally seen this with Unix installers from commercial software vendors.
You get a giant .sh file that displays a license, asks you to accept, then upon acceptance, cats itself, pipes through head/tail, into cpio to extract the actual assets.
Furthermore, the attacker covered their tracks on the initial payload with an innocuous paragraph in the README. ("Nothing to see here!")
bad-3-corrupt_lzma2.xz has three Streams in it. The first and third
streams are valid xz Streams. The middle Stream has a correct Stream
Header, Block Header, Index and Stream Footer. Only the LZMA2 data
is corrupt. This file should decompress if --single-stream is used.
The strings of `####Hello####` and `####World####` are there so that if you actually follow the instructions in the README, you get a seemingly valid result.
They're shell comments so it won't interfere with payload execution.
And lastly, they act as a marker that can be used by a later regex to locate the file _without_ referencing it by name directly nor using the actual Hello and World strings.
Change Healthcare is a transaction clearinghouse, or effectively an API, translation, and routing gateway.
Think of it as a private SWIFT vendor.
They were acquired by UHC, which is why you see the Optum name. But this is not specific to UHC/Optum patients.
Providers (hospitals, doctors, software vendors) interface with CH’s REST+JSON APIs and in turn CH emits EDI records to the insurance company backends (and translate the responses from EDI to JSON/XML/etc).
This affects general healthcare EDI messages (claims, benefits eligibility verification, ACH notices, etc).
The people impacted do not have direct EDI implementations with the insurance companies. If they did, they could side step this.
