In fact, security researchers behind the Def Con 21 talk "This presentation will self-destruct in 45 minutes: A forensic deep dive into self-destructing messages" looked at Snapchat, Facebook Poke and Wickr Wickr was the only one they could not penetrate. At the TechCrunch Disrupt conference, Snapchat co-founder Evan Spiegel said more than 350 million pictures are sent through Snapchat every day, but he reminded people, "Snapchat is not a great way to send photos you want to keep safe and secure." From a digital forensic point of view, the metadata is stored for Snapchat images. It is possible to secretly save videos, or a person could use Snap Save and the sender would not be alerted the image was saved. Then there's Snapchat, which has a "bad reputation as a self-destructing sexting app for teens," and it's not secure. Although Silent Circle is great from a security and privacy angle, it is not free there is a monthly fee. Wickr is not the only self-destruct messaging app. Robert Statica, Wickr cofounder and CTO, announced that the app went multi-platform with the introduction of an Android Beta version to "provide the masses free private international messaging." He noted additional layers of security beyond perfect forward secrecy: "Users are anonymous each message is bound to the device metadata is cleared from attachments all deleted files on your phone are shredded. We do not share or sell any data about our users. When you delete a message, or when a message expires, our "secure file shredder" technology uses forensic deletion techniques to ensure that your data can never be recovered by us or anyone else. Regarding the use of military-grade encryption, Wickr states, "Our encryption is based on 256-bit symmetric AES encryption, RSA 4096 encryption, ECDH521 encryption, transport layer security, and our proprietary algorithm."ĭeletion is forever. Wickr also takes security very seriously. Because of this we donʼt know - and canʼt reveal - anything about you or how you use the Wickr App." Your information is always disguised with multiple rounds of salted, cryptographic hashing before (if) it is transmitted to our servers. You may not be a fan of reading privacy policies, but you really should check out Wickr's to learn how the app provides the best available privacy and anonymity features. Only the intended recipient(s) on the intended devices can decrypt the messages." Wickr severs do not even have the decryption keys, your messages can never be accessed, "therefore, no criminal or rogue government can take them from us." Each message is encrypted with its own unique key. By using Perfect Forward Secrecy, the "encryption keys are unique, used only once and then forensically destroyed. They publish transparency reports that show the number of government requests for data, not that they could hand over the content of Wickr messages even with a properly issued subpoena. The security and privacy experts behind Wickr believe privacy is a fundamental human right. The agent asked for a secret backdoor, but Wickr said no. Nico Sell, CEO and co-founder of Wickr, said she was approached by the FBI at the RSA security conference. We can scarcely go a day without hearing about government surveillance or three-letter agencies pushing to have secret backdoors built into software. Unlike those apps, Wickr uses Perfect Forward Secrecy, offering you a chance to "leave no trace." Wickr for iPhone launched more than a year ago, but now the Android version is here! Wickr is setup so it is technically impossible for its creators to access your messages. Equally terrific, the experts behind Wickr say it's your data you own it. If you have an Android or an iPhone, and if you value privacy and security, then please do yourself a tremendous favor today by installing Wickr, a self-destructing messaging app that uses military-grade encryption for texts, pictures, audio, video and PDFs and also exceeds NSA's compliancy standards for Top Secret communications.
