Torpedo was in November 2012. In late July 2013, computer security experts detected a similar attack through Dark Net websites hosted by a shady ISP called Freedom Hosting—court records have since confirmed it was another FBI operation. For this one, the bureau used custom attack code that exploited a relatively fresh Firefox vulnerability—the hacking equivalent of moving from a bow-and-arrow to a 9-mm pistol. In addition to the IP address, which identifies a household, this code collected the MAC address of the particular computer that infected by the malware. “In the course of nine months they went from off the shelf Flash techniques that simply took advantage of the lack of proxy protection, to custom-built browser exploits,” says Soghoian. “That’s a pretty amazing growth … The arms race is going to get really nasty, really fast.” ]]> fbi tor police flash security privacy anonymity darknet wired via:bruces https://pinboard.in/ https://pinboard.in/u:jm/b:a28ff6afb74e/ 2014-11-23T23:28:29+00:00 http://www.beerlabelizer.com/ jm beer labels generator flash design bottling https://pinboard.in/ https://pinboard.in/u:jm/b:c4caa7b941ca/ 2013-11-15T09:54:52+00:00 http://rocksdb.org/ jmRocksDB builds on LevelDB to be scalable to run on servers with many CPU cores, to efficiently use fast storage, to support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation. We benchmarked LevelDB and found that it was unsuitable for our server workloads. Thebenchmark results look awesome at first sight, but we quickly realized that those results were for a database whose size was smaller than the size of RAM on the test machine - where the entire database could fit in the OS page cache. When we performed the same benchmarks on a database that was at least 5 times larger than main memory, the performance results were dismal. By contrast, we've published the RocksDB benchmark results for server side workloads on Flash. We also measured the performance of LevelDB on these server-workload benchmarks and found that RocksDB solidly outperforms LevelDB for these IO bound workloads. We found that LevelDB's single-threaded compaction process was insufficient to drive server workloads. We saw frequent write-stalls with LevelDB that caused 99-percentile latency to be tremendously large. We found that mmap-ing a file into the OS cache introduced performance bottlenecks for reads. We could not make LevelDB consume all the IOs offered by the underlying Flash storage.
