Therefore, it’s always OK to reference self when assigning a lazy variable. Which in turn means that it can’t be accessed until self exists, because otherwise there’s no way to access it. The point of the lazy variable is that it won’t be assigned until its needed. What do you do if you want to use one of these objects as a property, but also use self as the delegate? And that leads to a terrible head-scratcher. In all these cases, you have to provide the object with its delegate (or target) at initialization time. Using Lazy Variables to Work Around Swift Initialization Rules Organizations which want to maintain this visibility will need to update their tools and techniques. As online services start adopting TLS 1.3, organizations which rely on passive sniffing of encrypted connections may start losing visibility into those connections. TLS 1.2 is still completely supported and will be for a long time. Unfortunately it’s also used by legitimate security tools for more efficient monitoring. This is a pretty big weakness, which has been used in attacks. We call this Perfect Forward Secrecy, if you want to look it up. The proposed updates to TLS use a different key for every connection, so there is no master key which could allow unrestricted monitoring. They could also decrypt any previously recorded traffic protected with that key. It could enable someone with a copy of the master key to sniff all encrypted traffic. What exactly is the security weakness TLS 1.3 eliminates? – Version 1.3 eliminates support for an older way of setting up encrypted connections using a master key. This is impossible to verify.Ĭontacts iOS iOS 10 iOS App Privacy Sarahah Although Sarahah does in some cases ask for permission to access contacts, it does not disclose that it uploads such data, nor does it seem to make any functional use of the information.Īfter this piece was published, the app’s creator, Zain al-Abidin Tawfiq, tweeted that the contacts functionality would be removed in a future release and had been intended for a “‘find your friends’ feature.” He later told The Intercept the feature was stymied by “technical issues” and that a partner, who he has since stopped working with, was supposed to remove it from the app but “missed that.” He claims the functionality was, however, removed from the server and that Sarahah stores no contacts in its databases. When launched for the first time, it immediately harvests and uploads all phone numbers and email addresses in your address book. But the app is collecting more than just feedback messages. Sarahah bills itself as a way to “receive honest feedback” from friends and employees. Sarahah Quietly Uploads Your Address Book
