CISA has also announced that the Log4j vulnerabilities are now included in the Hack DHS bug bounty program. The program is originally announced on December 14th by the Department of Homeland Security to identify their systems’ flaws. With the recent chaos, the Log4j is immediately added to the program.
In response to the recently discovered log4j vulnerabilities, @DHSgov is expanding the scope of our new #HackDHS bug bounty program and including additional incentives to find and patch log4j-related vulnerabilities in our systems.
