Before its debut, Anthropic's frontier red team tested Opus 4.6 in a sandboxed environment to see how well it could find bugs in open-source code. The team gave the Claude model everything it needed to do the job - access to Python and vulnerability analysis tools, including classic debuggers and fuzzers - but no specific instructions or specialized knowledge. Claude found more than 500 previously unknown zero-day vulnerabilities in open-source code using just its "out-of-the-box" capabilities,
"The F-Droid project cannot require that developers register their apps through Google, but at the same time, we cannot 'take over' the application identifiers for the open-source apps we distribute, as that would effectively seize exclusive distribution rights to those applications," he said. "If it were to be put into effect, the developer registration decree will end the F-Droid project and other free/open source app distribution sources as we know them today," said Prud'hommeaux.
