Java-based malware driving DDoS botnet infects Windows, Mac, Linux devices

Java-based malware driving DDoS botnet infects Windows, Mac, Linux devices | 21st Century Learning and Teaching | Scoop.it
From arstechnica.com - January 29, 2014 10:34 AM
Multi-platform threat exploits old Java flaw, gains persistence.

 

Researchers have uncovered a piece of botnet malware that is capable of infecting computers running Windows, Mac OS X, and Linux that have Oracle's Java software framework installed.

 

The cross-platform HEUR:Backdoor.Java.Agent.a, as reported in a blog post published Tuesday by Kaspersky Lab, takes hold of computers by exploiting CVE-2013-2465, a critical Java vulnerability that Oracle patched in June. The security bug is present on Java 7 u21 and earlier. Once the bot has infected a computer, it copies itself to the autostart directory of its respective platform to ensure it runs whenever the machine is turned on.

 

Compromised computers then report to an Internet relay chat channel that acts as a command and control server.

Angriff auf aktuelle Java-Versionen

Angriff auf aktuelle Java-Versionen | 21st Century Learning and Teaching | Scoop.it
From www.heise.de - March 1, 2013 5:01 AM
Cyber-Kriminelle versuchen eine bislang unbekannte Java-Schwachstelle auszunutzen. Betroffen ist auch der 6er Versionszweig, den Oracle nicht mehr pflegt.
Gust MEES's insight:

Schützen kann man sich, indem man Java komplett deinstalliert oder zumindest innerhalb der Browser abschaltet. Nützlich ist auch die Click-to-Play-Funktion von Firefox und Chrome, durch die man der Ausführung von Plug-ins zunächst explizit zustimmen muss.

Use one browser where Java is disabled for normal surfing! Use a second one where Java is enabled for making eBanking + other sites which require Java...

 

Make sure YOU have the last update and delete ALL previous versions of JAVA on your hard disk!

Cross-platform malware exploits Java to attack PCs and Macs | ZDNet

Cross-platform malware exploits Java to attack PCs and Macs | ZDNet | 21st Century Learning and Teaching | Scoop.it
From www.zdnet.com - May 1, 2012 2:51 PM

The same Java vulnerability used in the infamous Flashback malware is now being used as an attack vector for a single piece of malware that can infect both Windows and Mac OS X computers.

 

Security vendors have discovered a new piece of malware that attacks both PCs and Macs. It uses the same Java security vulnerability exploited by the Flashback malware that infected hundreds of thousands of Macs. While the attack vector is the same as in Flashback, this Java Applet checks which OS it is running on and downloads suitable malware for it.

2 Programme verursachen 78 Prozent aller Schwachstellen

2 Programme verursachen 78 Prozent aller Schwachstellen | 21st Century Learning and Teaching | Scoop.it
From www.pcwelt.de - July 28, 2013 10:59 AM
Die meisten Schadprogramme nutzen bekannte Lücken in populärer Software aus. Dabei handelt es sich sogar nur um ganz wenige Tools, die einen Großteil der insgesamt bekannten Sicherheitslücken auf sich versammeln.

 

Hält man diese wenigen Programme immer auf dem aktuellen Stand, dann ist der eigene Windows-Rechner bereits relativ sicher. Mit wenig Aufwand erreicht man also viel Sicherheit.

Apple's own Macs bitten by Java-based malware attack

Apple's own Macs bitten by Java-based malware attack | 21st Century Learning and Teaching | Scoop.it
From nakedsecurity.sophos.com - February 19, 2013 3:52 PM
Apple released a statement today acknowledging that they were victims of the same attackers that Facebook talked about last week. A zero-day Java vulnerability infected Apple Mac developers through...

 

According to Reuters, "Apple Inc. was recently attacked by hackers who infected the Macintosh computers of some employees".

 

More specifically Apple engineers had their Mac OS X laptops infected by the same zero-day Java vulnerability that infected Facebook last month.

 

In a statement Apple made to The Loop an Apple spokesperson said “The malware was employed in an attack against Apple and other companies, and was spread through a website for software developers.

 

Gust MEES's insight:

What should you do as a result of this? If you are a Mac user you should be sure to keep your computer patched. Apple stated they will be releasing a Java malware removal tool this afternoon to respond to this attack.

 

It is also a good idea to run an up to date anti-virus to detect any future attacks and to disable Java in the browser if you don't require it for day to day web surfing.

 

===> To be fair, that advice applies to all computer users whether they prefer Windows, OS X or Linux. Many times staying safe isn't convenient, but it is an investment that pays off in the long run. <===
