Malware stored in synthetic DNA can take over PC: Study

Discovery of a new hacking method reverberates as DNA data storage becomes more widespread

University of Washington researchers figured out a way to use biology to infect computers with malicious code.

In their experiments, the researchers stored malware in synthetic DNA and demonstrated how that code can compromise a computer analyzing the DNA after it has been run through a gene-sequencing machine.

The danger of such an attack is still years away, the researchers said, adding they haven’t seen evidence of hackers attempting this sort of breach. The experiments highlight a new type of threat that could allow sophisticated coders to gain control of computer systems if precautions aren’t taken.

“This is something [the genomics industry] and the U.S. government should be concerned about,” said Tadayoshi Kohno, a computer-science professor at the university and a member of the research team.

The team will present the results of its experiments, conducted in late 2016 and 2017, at a security symposium in Vancouver, British Columbia, Canada, on Aug. 17.

The hack makes use of technology in which digital bits of data are converted into synthetic DNA. Researchers believe DNA data storage could prove far more durable than stashing information on hard disks and flash drives, which last just a few years and can crash without warning. The nascent technology converts the 1s and 0s of computing’s binary code into A, C, G and T, the letters that correspond to DNA base types, adenine, cytosine, guanine and thymine. Read more

Billing for 800,000 affected as ransomware hits power company in Bengal

However, Wannacry has proved less severe than anticipated in Asia

The global Ransomware Attack has affected several computers of a state power distribution company in West Bengal but the central government computer system has largely escaped, officials said on Monday.

State agencies that manage government websites and build supercomputers have installed security patches issued by Microsoft Corp.

Federal Minister Ravi Shankar Prasad told reporters that there was no serious impact on India, with only isolated incidents in parts of Kerala and Andhra Pradesh states, and the government was monitoring the situation.

However, West Bengal Power Minister Sovandev Chattopadhyay told Reuters that several billing centres of the state's Electricity Distribution Company Ltd (WBSEDCL) had been infected by the ransomware worm.

"The full extent and magnitude of the problem will be realised by tomorrow," he said, the situation will be very serious if household electricity consumption data from the central server of the utility could not be retrieved beforehand.

A power department official who did not want to be named said billing for around 800,000 households was affected when the ransomware blocked access to files in the computers.

A senior official at the Federal Ministry of Electronics and Information Technology said its Computer Emergency Response Team was gathering all possible information about the ransomware. Read more
