But now, 40 cities in the United States (including San Francisco, Los Angeles, New York and Washington), as well as London, Sydney, and other cities in nine other countries are adopting Sensys Networks wireless. They choose it because its components are relatively inexpensive ($ 500 per sensor and $ 3,000 per access point) and fairly simple to implement. But not safe enough, according to Cerrudo.
“I bought them myself because I wanted to study the communication protocols they use. I was able to see that the data travels without encryption, that is, it can be intercepted and changed. Furthermore, the devices do not have authentication: they do not ask for a username or password, and thus anyone who connects can enter false data, ”Cerrudo tells Clarín. The Argentine hacker, who works for a computer security company, did not stay in the laboratory. With his notebook and a small radio frequency transmitter, he traveled to New York to see if he could get into the system that regulates traffic in that city.
And he achieve it. In addition, he installed the transmitter on a drone (unmanned aerial vehicle) to demonstrate that the system can be altered remotely. All the information, documented, is what he then used for the work he recently presented at the international conference InfilTrate.
– Yes, although the important thing is not the number of traffic lights that are modified, but the strategy used. Just by deconfiguring two main corners can create chaos.
A Colombian judge ordered the release of alleged hacker Andrés Sepúlveda, accused of spying on the government and the FARC during the peace negotiations, citing lack of evidence from the prosecution, which opened a criminal investigation against the magistrate.
A Colombian judge ordered this Monday to release the alleged hacker Andrés Sepúlveda, accused of spying on the government and the FARC during the peace negotiations, citing lack of evidence from the prosecution, which opened a criminal investigation against the magistrate.
“The judge (Teresita Barrera) considered that the criminal procedure requirements were not met to proceed with an assurance measure,” added Bernardo Alzate, Sepúlveda’s lawyer, in an interview with the Cablenoticias channel.
Faced with this judicial decision, the attorney general of the Nation, Eduardo Montealegre, announced a criminal investigation against Barrera for possible “responsibility in the crime of prevaricate per action,” according to a statement from the prosecution.
“In an inexplicable way, Judge Barrera considered that the acceptance of responsibility made by Mr. Sepúlveda and the confidential documents found in his possession could not be taken into account as the basis of the accusation,” the text indicated.
