A new study from email security company Mimecast shows that malicious links in emails are being missed by many security systems. From a report: Mimecast examined more than 142 million emails that had passed through organizations’ email security vendors. The latest results reveal 203,000 malicious links within 10,072,682 emails were deemed safe by other security systems — a ratio of one unstopped malicious link for every 50 emails inspected. The report also finds an 80 percent increase impersonation attacks in comparison to last quarters’ figures. Additionally, 19,086,877 pieces of spam, 13,176 emails containing dangerous file types, and 15,656 malware attachments were all missed by these incumbent security providers and delivered to users’ inboxes.

The United States’ top spy catcher said Chinese espionage agencies are using fake LinkedIn accounts to try to recruit Americans with access to government and commercial secrets, and the company should shut them down. From a report: William Evanina, the U.S. counter-intelligence chief, told Reuters in an interview that intelligence and law enforcement officials have told LinkedIn, owned by Microsoft, about China’s “super aggressive” efforts on the site. He said the Chinese campaign includes contacting thousands of LinkedIn members at a time, but he declined to say how many fake accounts U.S. intelligence had discovered, how many Americans may have been contacted and how much success China has had in the recruitment drive. German and British authorities have previously warned their citizens that Beijing is using LinkedIn to try to recruit them as spies. But this is the first time a U.S. official has publicly discussed the challenge in the United States and indicated it is a bigger problem than previously known.

Everybody wants to give FPGA development a try and here’s a great way to get into it. You can build your own Persistence of Vision display using a $30 dev board. It’s a fun project, and you’ll learn quite a bit about designing for an FPGA, as well as using the Quartus design software.
The inspiration for this article comes from [vpecanins] who did an example project where you wave the board back and forth and a message appears in mid air. This uses the MAX1000, a pretty powerful yet odd FPGA board for about $30. It contains an Intel MAX10 (when did Intel start making FPGAs? Remember, Intel bought Alterra back in 2015). I find the board odd because it also holds an accelerometer that you can talk to using SPI. That’s a little strange for a generic FPGA board, but paired with eight on-board LEDs it’s perfect for this demo.
Since I didn’t find any written documentation for this example, I thought we’d help out and take you on a step-by-step tour of the project. What’s more, in a future installment, I’ll show you how to make some significant changes to the tutorial that will make it even more practical as a base for other projects.
Just for motivation, have a look at the video below to see what the project does. I modified the text (WD5GNR is my call sign), of course. The effect is better in real life, but the video will give you the idea. The FPGA monitors the accelerometer reverses the order for flashing the LEDs on and off to form the characters. It is a pretty impressive demo since it takes advantage of the unique features of the board, is non-trivial, and isn’t too much Verilog to swallow if you are just getting started.
To start with, you’ll need to install Quartus. The Lite edition is free and very capable. You can download the files and open the test0.qpf file in the demo02_led_text directory. You may get a nasty dialog about replacing the database if you have a newer version of Quartus than the original files used. You can safely agree to that.
On the project navigator inside Quartus, you can select Files and you’ll see the project has only a few:
- top.v – The main Verilog code.
- programming_chain.cdf – This file should tell Quartus how to program the configuration into the chip, but it is missing. That’s not a problem though. It isn’t really necessary and it is easy to recreate.
- font_rom.qip – A component that uses Altera IP (Intellectual Property) to create a ROM with the character patterns in it.
- spi_master.v – Code for talking to the accelerometer.
- macro.do – This file doesn’t actually exist and is apparently left over from the author’s earlier efforts.
- sequencer.v – Code for using the accelerometer.

New research has shown just how bad AI is at dealing with online trolls. From a report: Such systems struggle to automatically flag nudity and violence, don’t understand text well enough to shoot down fake news and aren’t effective at detecting abusive comments from trolls hiding behind their keyboards. A group of researchers from Aalto University and the University of Padua found this out when they tested seven state-of-the-art models used to detect hate speech. All of them failed to recognize foul language when subtle changes were made, according to a paper [PDF] on arXiv. Adversarial examples can be created automatically by using algorithms to misspell certain words, swap characters for numbers or add random spaces between words or attach innocuous words such as ‘love’ in sentences.
