Chinese Hackers Exploit Old ThinkPHP Flaws: The Persistent Dama Web Shell Strikes Again
Chinese threat actors are exploiting old vulnerabilities in ThinkPHP applications to install the Dama web shell. This malicious campaign leverages CVE-2018-20062 and CVE-2019-9082, turning compromised systems into nodes for further attacks. Remember, in cybersecurity, age is no defense against persistent threats!

Hot Take:
Why settle for fresh exploits when you can dust off some golden oldies? Chinese threat actors are proving that with a little nostalgia and a lot of persistence, you can wreak havoc using vulnerabilities older than your average houseplant. Time to patch up, folks, because these cybercriminals are turning your forgotten flaws into their personal playgrounds!
Key Points:
- Chinese threat actors are targeting ThinkPHP applications vulnerable to CVE-2018-20062 and CVE-2019-9082.
- The attackers use these vulnerabilities to install a persistent web shell named Dama.
- Dama enables further exploitation, including enlisting breached endpoints in the attackers’ infrastructure.
- The campaign has expanded and intensified since October 2023.
- Recommended mitigation includes updating to ThinkPHP version 8.0 to avoid these known remote code execution bugs.
