Deleted again, back again. It lived in <strong>at least 8 places</strong>, the server&rsquo;s memory too, and had <strong>a hidden admin that could log in without a password</strong>.</p> <p>That is what the cleanup team at <strong>Sucuri</strong> ran into on a site they were called in to fix. They removed the malware carefully, file by file, and the same backdoor kept returning within seconds of each removal. Their analyst <strong>Gabriel Barbosa</strong> published the full breakdown on <strong>30 September</strong>. The researchers call the family <strong>SC</strong>, after the &ldquo;SC_&rdquo; markers they found in the injected code.</p>
