'Sophisticated' backdoor malware opens up security blackhole in Apache web servers

'Sophisticated' backdoor malware opens up security blackhole in Apache web servers | ICT Security-Sécurité PC et Internet | Scoop.it
Malware that hides itself from admins has been found in the wild, allowing attackers to compromise web servers and redirect users to sites hosting exploit kits.

 

Researchers at security firm ESET have dubbed the malware Linux/Cdorked.A and are calling it "the most sophisticated Apache backdoor" due to its ability to evade detection. 

 

===> Apache web servers run about 50 percent of the world’s websites, according to UK-based internet security firm, Netcraft. <===

 

The researchers claim the malware has been installed on hundreds of compromised web servers, which have served up malicious redirects to thousands of visitors.

Apache attack drives traffic to malware

Apache attack drives traffic to malware | ICT Security-Sécurité PC et Internet | Scoop.it

 

A security researcher is warning that an attack on the Apache Web server is increasingly showing up in the wild, and has published a free Python tool to check their configurations.

 

The attack is designed to avoid leaving disk footprints, according to this post analysing the backdoor. It exists as a modified httpd file that redirects HTTP requests to the well-known Blackhole exploit pack.

Apache guns down killer server bug

Apache guns down killer server bug | ICT Security-Sécurité PC et Internet | Scoop.it
Absent forward slash leaves a gaping hole.

 

The Apache Software Foundation has squashed a reverse proxy flaw affecting its servers in which little more than a missing forward slash had exposed untold numbers of network devices and information to hackers.

 

Reverse proxies route external HTTP and HTTPS web requests to an internal web server. It is used in load balancing and to make multiple web servers at different paths appear as a single web interface.

Backdoor entdeckt: Angreifer kaperten schon hunderte Apache-Server

Backdoor entdeckt: Angreifer kaperten schon hunderte Apache-Server | ICT Security-Sécurité PC et Internet | Scoop.it
Bösartige Angreifer kapern Apache-Webserver und leiten deren Besucher auf Schad-Websites um. Die Tarnung der Malware ist fast perfekt.

 

Eine Hintertür, die von Administratoren nur schwer bemerkt werden kann, sorgt dafür, dass Internet-Anfragen an Apache-Server nicht in Logs aufgenommen werden. Die gesendeten http-Anfragen, die in Wirklichkeit einen Trojaner steuern, sind nicht ersichtlich. Der Rest des Angriffs läuft im Speicher ab, Bugfixes gibt es noch nicht.

Die Malware Linux/Cdorked.A ist eine raffinierte Hintertür, die alles tut, um den Internetverkehr auf schädliche Webseiten umzuleiten, schreibt Sicherheitsanbieter Eset in einer aktuellen Warnung.   Der Schädling sei so gut, dass er laut eigener Analysen schon hunderte von Webservern unter seine Kontrolle gebracht habe.
