"While playing around with the Nmap Scripting Engine (NSE) we discovered an amazing number of open embedded devices on the Internet. " After completing the scan of roughly one hundred thousand IP addresses, we realized the number of insecure devices must be at least one hundred thousand. Starting with one device and assuming a scan speed of ten IP addresses per second, it should find the next open device within one hour. The scan rate would be doubled if we deployed a scanner to the newly found device. After doubling the scan rate in this way about 16.5 times, all unprotected devices would be found; this would take only 16.5 hours. Additionally, with one hundred thousand devices scanning at ten probes per second we would have a distributed port scanner to port scan the entire IPv4 Internet within one hour. [more inside]
An advanced and well-orchestrated computer spy operation that targeted diplomats, governments and research institutions for at least five years has been uncovered by security researchers in Russia.

Apple released a fix for the Java exploit yesterday, some six weeks after Microsoft, Adobe, and Oracle released their fixes.
A botnet with 6 to 12 million computers, employing the world's most sophisticated encryption and peer to peer communication lies waiting, but for what? When the Conficker computer “worm” was unleashed on the world in November 2008, cyber-security experts didn’t know what to make of it. It infiltrated millions of computers around the globe. It constantly checks in with its unknown creators. It uses an encryption code so sophisticated that only a very few people could have deployed it. For the first time ever, the cyber-security elites of the world have joined forces in a high-tech game of cops and robbers, trying to find Conficker’s creators and defeat them. The cops are failing. And now the worm lies there, waiting … [via Postroad's rich linkdump: Goodsh*t (nsfw)] [more inside]
When Ron Paul email spam started hitting inboxes in late October, UAB Computer Forensics Directory Gary Warner published findings on the spam's textual patterns and the illicit botnet used to spread it -- findings which were picked up by media outlets and tech websites like Salon, Ars Technica, and Wired Magazine's "Threat Level" blog, the latter in a set of followup posts by writer Sarah Stirland: 1, 2, 3.
