A flaw in the way Snapchat handles user-verification tokens makes the image-messaging service vulnerable to a denial-of-service attack that can crash iPhones, two Spanish researchers say. The researchers, Jaime Sanchez and Pablo San Emeterio, first detailed the flaw in a Spanish-language blog posting Jan. 12, then presented their findings at the ShmooCon security conference in Washington, D.C. on Jan. 18. But it was not until Sanchez spoke to reporter Salvador Rodriguez of the Los Angeles Times for a story published yesterday (Feb. 7) that the flaw got widespread attention.
