So say researchers in Singapore, a country where skyscrapers are plentiful.In this video, researchers from iTrust, a Center for Research in Cyber Security at the Singapore University of Technology And Design, show how attackers could infiltrate a wireless printer using a personal drone and an Android phone outfitted with a special app.MORE: New super-precise drones could win over wireless carriersTo read this article in full or to leave a comment, please click here

IDG Contributor Network: More data breaches caused by lost devices than malware or hacking, Trend Micro says

Prices are dropping for Personally Identifiable Information (PII) on the Dark Web. One likely reason is a surplus of the data; cybercriminals have been too successful gathering the stuff. Criminals can now purchase PII for $1 a line — that's down from $4 just a year ago, Trend Micro reported in its new research paper. Each line contains a name, a full address, a date of birth, a Social Security number, and other information. Criminals only need a few lines to clone an identity.Studying stolen data Trend Micro analyzed a decade's worth of data breach information in its new report, "Follow the Data, Dissecting Data Breaches and Debunking the Myths' (PDF).To read this article in full or to leave a comment, please click here

Your Load Generator is Probably Lying to You – Take the Red Pill and Find Out Why

Pretty much all your load generation and monitoring tools do not work correctly. Those charts you thought were full of relevant information about how your system is performing are really just telling you a lie. Your sensory inputs are being jammed. 

To find out how listen to the Morpheous of performance monitoring Gil Tene, CTO and co-founder at Azul Systems, makers of truly high performance JVMs, in a mesmerizing talk on How NOT to Measure Latency.

This talk is about removing the wool from your eyes. It's the red pill option for what you thought you were testing with load generators.

Some highlights:

  • If you want to hide the truth from someone show them a chart of all normal traffic with one just one bad spike surging into 95 percentile territory. 

  • The number one indicator you should never get rid of is the maximum value. That’s not noise, it’s the signal, the rest is noise.

  • 99% of users experience ~99.995%’ile response times, so why are you even looking at 95%'ile numbers?

  • Monitoring tools routinely drop important samples in the result set, leading you to draw really bad conclusions about the quality of the performance of Continue reading
