Botnetze werden oft über zentrale Kommando-Server, auch als Mutterschiffe bezeichnet, gesteuert. Die infizierten Rechner, Zombies genannt, halten Kontakt mit einem der Mutterschiffe oder untereinander. Sie geben ausgespähte Daten wie etwa Passwörter für Online-Spiele und Banken-Websites, aber auch gesammelte Mail-Adressen oder Kreditkartendaten weiter. Sie erhalten vom Mutterschiff, teils über zwischen geschaltete Relay-Rechner (Repeater), Instruktionen, etwa Adressen und Inhalte von zu versendenden Spam-Mails.

Gust MEES's insight:

An average of 19 vulnerabilities per day were reported in 2014, according to the data from the National Vulnerability Database (NVD). In this article, I look at some of the trends and key findings for 2014 based on the NVD’s database.

#Mac OS X and #Linux had more #vulnerabilities in 2014 than ALL #Windows Versions in sum.

Not surprisingly at all, web browsers continue to have the most security vulnerabilities because they are a popular gateway to access a server and to spread malware on the clients. Adobe free products and Java are the main challengers but web browsers have continuously topped the table for the last six years. Mozilla Firefox had the most vulnerabilities reported in 2009 and 2012; Google Chrome in 2010 and 2011; Internet Explorer was at the top for the last two years.

To keep systems secure, it is critical that they are fully patched.IT admins should focus on (patch them first):

Operating systems (Windows, Linux, OS X)
Web browsers
Java
Adobe free products (Flash Player, Reader, Shockwave Player, AIR).

Gust MEES's insight:

Gezielte, gut getarnte Phishing-Attacken sind große Gefahr für Unternehmen.

Der Security-Software-Hersteller ESET rät Unternehmen zu einer verstärkten Sensibilisierung für Phishing-Attacken und damit einhergehend zu einer besseren IT-Weiterbildung. Nur so können die eigenen Mitarbeiter vor gezielten und gut getarnten Angriffen geschützt werden. Denn Attacken dieser Art sind mittlerweile geschickt auf ihre Zielgruppen zugeschnitten und nur mit großer Sorgfalt und Verständnis erkennbar.

Anlass für den Ratschlag ist das Ergebnis eines Tests, den das Center of Excellence for Research, Innovation, Education and Industrial Labs Partnership (CEFRIEL) im Auftrag von 15 internationalen Unternehmen kürzlich durchführte. Die Einrichtung prüfte die Anfälligkeit von Mitarbeitern für speziell auf Unternehmen gemünzte Betrugsversuche, so genannte „Spear-Phishing“-Attacken. Das Ergebnis: Jeder Fünfte ging den Testern ins Netz.

Their typical purpose is to help sites remember particular actions you may have done there in the past.

Gust MEES's insight:

The closed-by-default ecosystem makes it harder for this malware to successfully take hold of the platform, but there remains a subsection of users who'll gladly disable Mac OS X security measures – especially people who use pirated software. This means that those looking to hijack OS X systems for a variety of reasons know that they simply need to bundle their malware with desirable software (probably in the form of a key generator) to enjoy widespread success.

Due to widespread beliefs about the security of the OS X platform, these systems are also unlikely to have an antimalware solution installed that will flag the infection so once the malware is installed, so it's likely to go unnoticed for a very long time.

Q. If I get a VPN (a virtual private network), will it protect the computer against malicious software?

A. A VPN encrypts the data that you send and receive over your Internet connection to protect it from snoopers looking to steal passwords and other information. If you use public wireless networks, using a VPN helps keep personal information private.

Computer users pass around USB sticks like silicon business cards. Although we know they often carry malware infections, we depend on antivirus scans and the occasional reformatting to keep our thumbdrives from becoming the carrier for the next digital epidemic. But the security problems with USB devices run deeper than you think: Their risk isn’t just in what they carry, it’s built into the core of how they work.

Contrairement aux idées reçues, Windows (toutes versions confondues) s’est révélé moins vulnérable que Mac OS X, iOS ou Linux. Toutefois, Microsoft n’a pas non plus de raison de pavoiser car Internet Explorer est l’application la plus vulnérable, très loin devant les autres.
