Infosec.exchange

infosec.exchange is an instance on the ActivityPub fediverse which allows the presence of CISA, a US "Homeland Security" agency. Because of this, many other instances are defederating from them, and TootCat decided on 2022-11-23 to invoke a silence on 11/30 so as to give users a chance to do any migration or following that would not be possible afterwards.

Incidents

• 2022-11-22 scholar.social/@researchfairy: «It took ~ 35 mins for users on infosec.exchange to start sending us harassing messages» after S.S briefly re-federated with I.E to allow a user to migrate there. (There is additional discussion in the thread.)

Discussion

• 2022-11-30 @woozle discusses the core issue and options for resolving it
• 2022-11-30 @dredmorbius asks: «@jerry Checking my understanding: CISA is an informational and advisory agency, not an intelligence agency per se. / It principally advises US organisations (commercial, governmental, and others) on practices and risks. It may have some monitoring elements. What it is not so far as I can tell is a surveillance or law enforcement entity. Though it does operate under the Dept. of Homeland Security. / As such, rationale for silencing an instance based on hosting CISA accounts seems ... questionable.»
