OOOOOOOOOOOOooooooooooooooooo helloooooo there
Gonna write up a full topic tomorrow(unless someone else beats me to it), an interesting hiccup in the above and other info.
I definitely like the idea of a security ticker/news-wire; but since at the moment this thread is not seeing many updates, might I recommend using the ISC Podcast and site as a source:
Seems to be the closest equivalent of what this thread aims to be.
Feel free to add when you come across things. I intend to pop things in here as i come across interesting or emerging info.

So, they bought something to build something that’s supposed to do something they claimed they’d be doing already?

Alert: Potential legacy risk from malware targeting QNAP NAS devices
Campaigns
The NCSC and CISA have identified two campaigns of activity for QSnatch malware. The first campaign likely began in early 2014 and continued until mid-2017, while the second started in late 2018 and was still active in late 2019. The two campaigns are distinguished by the initial payload used as well as some differences in capabilities. This alert focuses on the second campaign as it is the most recent threat.It is important to note that infrastructure used by the malicious cyber actors in both campaigns is not currently active, but the threat remains to unpatched devices.
Although the identities and objectives of the malicious cyber actors using QSnatch are currently unknown, the malware is relatively sophisticated, and the cyber actors demonstrate an awareness of operational security.
Global distribution of infections
Analysis shows a significant number of infected devices. In mid-June 2020, there were approximately 62,000 infected devices worldwide; of these, approximately 3,900 were in the UK and 7,600 were in the US.

GNU-TLS CVE-2020-13777
old notice, but of severity that I felt it important to include; was previously mentioned in News thread

CVE-2020-13777 GnuTLS audit: be scared
… You are reading this correctly: supposedly encrypted TLS connections made with affected GnuTLS releases are vulnerable to passive cleartext recovery attack (and active for 1.3, but who uses that anyways).
