jppiiroinen writes: At the end of 2007, when Nokia still had huge market share with Symbian devices, they failed to disclose that somebody had stolen their encryption keys and extorted them for millions of Euros. The Finnish National Bureau of Investigation has not been able to figure out who did it. "The blackmailer had gotten hold of the Symbian encryption key used for signing. The code is a few kilobytes in size. Had the key been leaked, Nokia would not have been able to ensure that the phones accept only applications approved by the company."

Researchers Outline Spammers' Business Ecosystem 14

An anonymous reader writes A team of researchers at the UC Santa Barbara and RWTH Aachen presented new findings on the relationship of spam actors [abstract; full paper here] at the ACM Symposium on Information, Computer and Communications Security. This presents the first end-to-end analysis of the spam delivery ecosystem including: harvesters crawl the web and compile email lists, botmasters infect and operate botnets, and spammers rent botnets and buy email lists to run spam campaigns. Their results suggest that spammers develop a type of "customer loyalty"; spammers likely purchase preferred resources from actors that have "proven" themselves in the past. Previous work examined the market economy of the email address market in preparatory work: 1 million email addresses were offered on the examined forum for anywhere ranging between 20 and 40 Euros.
