Hackers suspected of working on behalf of the Chinese government exploited a maximum-severity vulnerability, which had received a patch 16 months earlier, to compromise a telecommunications provider in Canada, officials from that country and the US said Monday. ArsTechnica: "The Cyber Centre is aware of malicious cyber activities currently targeting Canadian telecommunications companies," officials for the center, the Canadian government's primary cyber security agency, said in a statement. "The responsible actors are almost certainly PRC state-sponsored actors, specifically Salt Typhoon." The FBI issued its own nearly identical statement. Salt Typhoon is the name researchers and government officials use to track one of several discreet groups known to hack nations all over the world on behalf of the People's Republic of China. In October 2023, researchers disclosed that hackers had backdoored more than 10,000 Cisco devices by exploiting CVE-2023-20198, a vulnerability with a maximum severity rating of 10. Any switch, router, or wireless LAN controller running Cisco's iOS XE that had the HTTP or HTTPS server feature enabled and exposed to the Internet was vulnerable. Cisco released a security patch about a week after security firm VulnCheck published its report.

Scientists Use Bacteria To Turn Plastic Waste Into Paracetamol

Bacteria can be used to turn plastic waste into painkillers, researchers have found, opening up the possibility of a more sustainable process for producing the drugs. From a report: Chemists have discovered E coli can be used to create paracetamol, also known as acetaminophen, from a material produced in the laboratory from plastic bottles. "People don't realise that paracetamol comes from oil currently," said Prof Stephen Wallace, the lead author of the research from the University of Edinburgh. "What this technology shows is that by merging chemistry and biology in this way for the first time, we can make paracetamol more sustainably and clean up plastic waste from the environment at the same time." Writing in the journal Nature Chemistry, Wallace and colleagues report how they discovered that a type of chemical reaction called a Lossen rearrangement, a process that has never been seen in nature, was biocompatible. In other words, it could be carried out in the presence of living cells without harming them. The team made their discovery when they took polyethylene terephthalate (PET) -- a type of plastic often found in food packaging and bottles -- and, using sustainable chemical methods, converted it into a new material.

Caps of Glass Bottles Contaminate Beverages With Microplastics

Microplastics are present in all beverages, but those packaged in glass bottles contain more microplastic particles than those in plastic bottles, cartons or cans. This was the surprising finding of a study conducted by the Boulogne-sur-Mer unit of the ANSES Laboratory for Food Safety. The scientists hypothesised that these plastic particles could come from the paint used on bottle caps. Water and wine are less affected than other beverages. These findings have highlighted a source of microplastics in drinks that manufacturers can easily take measures to address.
