It’s Probably Nothing

Wired;

When biologists synthesize DNA, they take pains not to create or spread a dangerous stretch of genetic code that could be used to create a toxin or, worse, an infectious disease. But one group of biohackers has demonstrated how DNA can carry a less expected threat—one designed to infect not humans nor animals but computers.
 
In new research they plan to present at the USENIX Security conference on Thursday, a group of researchers from the University of Washington has shown for the first time that it’s possible to encode malicious software into physical strands of DNA, so that when a gene sequencer analyzes it the resulting data becomes a program that corrupts gene-sequencing software and takes control of the underlying computer.

Old tweets reveal hidden secrets

Researchers from the Foundation for Research and Technology in Greece and the University of Illinois found all this out after writing a tool called LPAuditor. The software mines publicly available tweet data that anyone can download from Twitter via its application programming interface (API).
 
Using the tool, they analyzed the metadata – hidden information about a tweet embedded in the post – to identify users’ homes, workplaces and sensitive places that they visited. In dozens of cases, they were also able to identify the users behind anonymous Twitter accounts.
