Hi everyone,
Every few days I've been getting an email saying that WordFence (v6.0.22 Free) has found a file that appears to be malicious in the WP Super Cache (v1.4.7) directory:
"* File appears to be malicious: wp-content/cache/meta/wp-cache-b772b3d569b52da8m.php"
Sometimes I'll go to the directory and the file won't be there, but the last time I opened the file I found it had base64 code, which is probably what's triggering the malicious file warning.
I've been keeping a close eye on the site, and haven't seen any defacements, or detected any added code in suspicious places, although I am aware WP Super Cache has had vulnerabilities two years ago relating to base64 decoded redirects and such.
Ben,
