Dopo l'ultima code injection [CVE-2015-8562] di Dicembre 2015, abbiamo deciso che ci serviva aiuto a identificare e rimuovere le infezioni, e abbiamo iniziato ad implementarlo in Little Helper.

LittleHelper dalla versione 2.4.0 ha una nuova funzione nella vista "Sicurezza": "Search for Exploits".

Nota: questa funzione è semplicemente uno strumento aggiuntivo; avrai ancora bisogno di aggiornare la tua versione Joomla, verificarla con un backup antecedente il 10 dicembre 2015, ed eseguire un antimalware.

Sebbene sia (ancora) estremamente semplice nell'approccio, Search for Exploits aiuta gli amministratori di sistema ed i webmaster ad identificare criticità potenziali nella loro installazione.

Short FAQ for versions 2.4.x

My antivirus complains

Yes, we know. Both the cache deletion and the jedchecker libraries contain calls that can be mistaken for viruses. At first, with just the cache calls, it was just one false positive per year, and it was something we could handle. But then with the jedchecker it simply became overwhelming. The feature is still available with version 2.5.9 and is not installed starting from version 2.6.1.  If you are updating a previous installation, and want to remove it manually, simply delete the two folders:

There is also a plan to make the cache cleaning more antivirus-friendly.

I get a timeout error

Your webserver configuration does not allow overriding the default timeout; this script currently takes 1 to 10 minutes to run, so it may very well exceed the default php timeout.  Either you change the configuration of the server, or you wait for the next and improved version*.

I get the error 'grep command not found'

This script relies on the gnu grep utility; if you're running on windows, or on limited hosting, this may not be available.  Wait for the next and improved version*.

This function dumps hundreds of lines

Alas, identifying malware is for human eyes; we can only attempt to spot patterns that could be used maliciously; but they can be used legitimately as well! Hover over the "info" and "code" elements in the JAMSS section of the results to see the relevant code.

I clicked and the report disappeared, do I have to run it again?

Alas, yes.  Wait for the next and improved version*.

What's with the "next and improved version"

We are perfectly aware this function leaves a lot to be desired in compatibiliy, usability, speed, effectiveness; nonetheless, we have at times found it useful and we thought we'd share it.  There are currently no plans for building a proper and more effective interface, as this will be addressed by TooManyFiles pro.
