America's top hacking contest shows that industrial control systems are pervasively flawed

According to the news of E Security Public Account on April 25, the 2022 Miami Pwn2Own Hacking Contest hosted by the Zero Day Initiative (ZDI) team under Trend Micro came to an end, and the participating teams found a total of 26 zero-day vulnerabilities and won $400,000 in prize money. The competition focuses on the theme of "Industrial Control Systems" and includes four categories: control servers, open platform communication unified architecture (OPC UA) servers, data gateways, and human-machine interfaces. Two cybersecurity personnel from the Netherlands won the Master of Pwn award and said it was the easiest competition they had ever competed in because there were so many "results" at their fingertips in industrial control systems. This shows that industrial control systems are an area where cybersecurity performance lags behind.

The U.S. research team introduced engineered lactococcus lactic acid into the intestines of mice, which protected intestinal probiotics while ensuring the efficacy of antibiotics

According to the news of Shenghui Public Account on April 25, the research team at the Massachusetts Institute of Technology in the United States used synthetic biology technology to design a system that ensures the efficacy of antibiotics and protects the intestinal microbiota from the effects of antibiotics. The researchers genetically engineered the Lactococcus lacticophyllum strain, an edible-safe strain commonly used to produce cheese, to produce β-lactamase that breaks down β-lactam antibiotics such as penicillin, ampicillin, and amoxicillin, and to form a barrier that protects the local gut microbiota from antibiotic damage while not reducing antibiotic levels in the bloodstream and maintains the bacterial diversity of the gut microbiome. In addition, this strategy can also effectively reduce the occurrence of antibiotic resistance in mice. The research team will continue to develop a Lactococcus lactate therapy for people at high risk of exacerbation of the disease due to antibiotic treatment. The research was published in the journal Nature Biomedical Engineering.

Turkey's AKINCI and TB-2 UAVs completed the sea target strike test for the first time

According to Seahawk News on April 26, Turkish drone manufacturer Baykar Company released a live-fire video of the AKINCI UAV, in which the AKINCI UAV carried an MK-82 bomb equipped with a Teber guidance kit and successfully hit a floating target at sea. In the test, a TB-2 drone found a target at sea and used an onboard laser pointer to illuminate the target to provide eye-pointing information for the AKINCI drone, which dropped an MK-82 bomb equipped with a Teber kit at an altitude of more than 6,000 meters, and the guided bomb received the laser beam of the TB-2 drone until it successfully hit the target. The trial successfully validated the feasibility of using TB-2 to provide an eye finger to carry out a sea strike.
