Scientists, clinicians, seed companies and others may soon have a new tool in their toolkit for detecting bacterial pathogens, thanks to a new study by researchers in Penn State’s College of Agricultural Sciences. The research—published in Journal of Microbiological Methods—details a new method for detecting Pseudomonas syringae, a common bacterium that infects a wide variety of crops, vegetables and woody ornamentals.

The cost is similar to that of the traditional method, called enzyme-linked immunosorbent assay, or ELISA. However, the researchers’ new method—called enzyme-linked chaperone assay, or ELCA—has the potential to detect only living bacteria, making it more sensitive and accurate.

Rachel Herschlag, lead author on the paper who earned her doctorate in plant pathology at Penn State, said the study is a proof of concept, with an opportunity in the future to adapt the method for detecting other pathogens.

WordPress will automatically review plugin releases and block high-risk updates after a backdoor was caught before distribution.

Malicious versions of the Admin Menu Editor Pro plugin for WordPress have been distributed to more than 200 customers after a threat actor compromised the maintainer’s website and pushed updates that created a hidden user account.

Developer Janis Elsts says an unauthorized party accessed the adminmenueditor.com website on Monday and uploaded version 2.35 as an update for the plugin’s Pro version. The update included an includes/wp-user-consent.php file that installed a web shell on affected websites.

After noticing the intrusion, Elsts removed the malicious update and pushed a clean version 2.36 on the same day at 19:00 UTC. However, the hacker still had access to the website and compromised the new version, too.
