Tiny Robotic Crab Is Smallest-Ever Remote-Controlled Walking Robot
Northwestern University engineers have constructed the smallest-ever remote-controlled walking robot, and it comes in the guise of a tiny, charming peekytoe crab.
The tiny crabs, which are only a half-millimetre across, can bend, twist, crawl, walk, turn, and even jump. In addition, the researchers created millimetre-sized robots that resemble inchworms, crickets, and beetles. Although the research is still in its early stages, the researchers hope their technology will help them get closer to developing micro-sized robots that can do practical jobs in constrained locations.
Today, the study was published in the journal Science Robotics (May 25). Last September, the same group unveiled the world’s smallest human-made flying structure, a winged microprocessor (published on the cover of Nature).
“Robotics is an interesting subject of research, and the development of robots is one of the most intriguing aspects of it.”

FBI Warns of Hackers Selling Credentials for U.S. College Networks
Cybercriminals are proposing to sell network access credentials for higher education institutions in the United States for thousands of dollars.
This form of marketing can be found on both publicly accessible cybercriminal internet forums and dark web marketplaces.
The Federal Bureau of Investigation (FBI) has issued an alert regarding Russian cybercriminal sites selling usernames and passwords that grant access to schools and universities in the United States.
Network credentials and virtual private network (VPN) access to “a multiplicity” of higher education organisations in the United States are among the sensitive data.
In other situations, the seller included a screenshot to demonstrate that the credentials grant the desired access.
The cost of such certifications ranges from a few dollars to several thousand.
Github Saved Plaintext Passwords of NPM Users in Log Files, Post Mortem Reveals
Following the incorporation of the JavaScript package registry into GitHub’s logging systems, the company discovered it retained a “number of unencrypted user credentials for the npm registry” in internal logs.
The information was revealed today when the business released the findings of its investigation into an unrelated OAuth token theft assault that occurred in April, in which an attacker stole data including the personal information of about 100,000 npm users.
The code shack went on to reassure users that the relevant log files had not been revealed in any data breach, that log cleansing had been enhanced, and that the logs in question had been purged “prior to the npm assault.”
