Government Trapdoors Spying Tool Could Decrypt Millions of Cryptographic Keys, Bitcoin is Safe
Law enforcement agencies and government organizations including the NSA could place trapdoors on millions of Diffie-Hellman-generated cryptographic keys to decrypt websites, applications, and encrypted messaging tools. It was revealed in a new study led by a team of University of Pennsylvania researchers. Since early 2000, the Diffie-Hellman (DH) key exchange has been considered as the backbone of many cryptographic systems due to its unique simultaneous key generation technique. During a DH exchange, two parties create a key together, which later can be used to encrypt the traffic.....

Security researchers have just discovered "one of the most advanced pieces of malware ever created." Symantec researchers recently published their findings on a Trojan they named "Regin." Regin has been in use since at least 2008 and has only now been discovered. Researchers state the tool is "a complex piece of malware whose structure displays a degree of technical competence rarely seen. It's been cleverly designed to spy on computer systems around the world while leaving hardly a trace behind. The software's authors have gone to great lengths to cover its tracks." Regin uses multiple....

The master decryption keys for the ransomware, CrySis, has been released to the public, news that will undoubtedly come as a pleasant surprise to those victimized by the malware. Another Ransomware Tool Bites the Dust. The decryption keys first became public when a user posted them on a the forums of bleepingcomputer.com. The user, known only as crss7777, posted the decryption keys on the forum at 1 AM Sunday morning. Researchers at Kaspersky Lab, who have recently launched an anti-ransomware campaign in conjunction with Intel Security and international law enforcement this summer, quickly....
A new project called Keybase is attempting to make cryptographic keys, like those used for bitcoin wallets, easier for everyone to use. One of the most important elements of bitcoin is arguably the cryptographic key pair, and every wallet has two keys: a public one as an advertised address, and a private one that controls it. Yet, the system is not perfect. Key pairs are confusing for many users and there isn't yet an effective, decentralized way by which keys can be linked to an identity, thus proving ownership. Keybase believes it can help make using keys more secure and understandable....
