ICE Block, an app that lets users warn others about the location of ICE officers, and which for a short while was the top of the social media App Store chart, does protect users privacy and doesnt share your location with third parties, according to a recent analysis from a security researcher. ICE Block already claimed that it did not collect any data from the app; the analysis now corroborates that.Its not uploading your location at all, when you make a report that report isnt associated with your device in any way, and there are no third party services that it talks to or sends data to, Cooper Quintin, senior public interest technologist at the Electronic Frontier Foundation (EFF), who analyzed the ICE Block app, told 404 Media.Do you know anything else about this app? I would love to hear from you. Using a non-work device, you can message me securely on Signal at joseph.404 or send me an email at joseph@404media.co.ICE Block lets users report nearby sightings of ICE officials. The app launched in April, but skyrocketed in popularity after CNN covered the app in June. Department of Homeland Security (DHS) head Kritsi Noem then said that were working with the Department of Justice to see if we can prosecute [CNN] for that.There is no indication that what ICE Block is doing is illegal, nor the coverage of the app. Its App Store page says Stay informed about reported ICE sightings, within a 5 mile radius of your current location, in real-time while maintaining your privacy.Joshua Aaron, ICE Blocks developer, told 404 Media there are no legal issues with the app. Multiple constitutional and criminal attorneys looked at it before it launched and all agreed this is protected under the First Amendment.He added Quintins analysis was great because he confirmed everything weve been saying about the app. It is 100% anonymous and we are not collecting or storing any identifiable user information. Aaron declined to say how much the app was costing to run. He said Apple has not contacted him at all about the app and doesnt expect them to.To analyze ICE Block, Quintin said he viewed its network traffic, which would show what data was being transferred or not, viewed logs, and looked up what software libraries were used in the app.404 Media recently reported on a different app called FuckLAPD.com that uses facial recognition to reveal the identity of LAPD officers. The developer of that project also made ICEspy, which is designed to provide the name of ICE officials, but at the time the underlying dataset was out of date.
