Stealthy Linux backdoor malware spotted after three years of minding your business??

openSUSE devs, Don't know if the powers that be are up on this, but quite alarming and I still can't figure out how to test for it. Apparently corrupt versions of systemd-daemon and gvfsd-helper have been used -- for years. https://www.theregister.com/2021/04/29/stealthy_linux_backdoor_malware_spott... Any body got more on this? -- David C. Rankin, J.D.,P.E.
