ICT Security-Sécurité PC et Internet

Hacker haben ungefähr 500 MByte an Daten aus dem Netzwerk des Jet Propulsion Laboratory (JPL) der Nasa erbeutet, indem sie einen Raspberry Pi als Einstiegspunkt nutzten. Der Bastelrechner war ohne Autorisierung in das Netzwerk eingebunden und entsprechend nicht ausreichend gesichert.

Der Angriff erfolgte bereits im April 2018 und blieb ein Jahr lang unentdeckt, wie Zdnet unter Berufung auf einen Bericht der Nasa schreibt. Der Zwischenfall ist unter anderem Thema eines Sicherheitsberichtes des Office of Inspector General (OIG) der Nasa, das firmeninterne Untersuchungen durchführt.

A proof of concept from security researcher and software developer Samy Kamkar shows that macOS, Windows, and Linux computers can have any previously active Web logins hijacked merely by plugging in a tiny Unix device via USB or Thunderbolt, even if the computer is locked and password protected, and possibly even when it seems to be asleep. It can also hijack many router brands on the same network.

PoisonTap exploits several interlocked network and browser design features, rather than relying on an operating system, hardware, or browser flaw. This will make it harder to root out and resolve. Kamkar said in an interview, “The interesting attacks to me are by design: how do you exploit the protocol rather than a single buffer overflow that gets patched the next day.”

It's time to update your Raspberry Pi devices or risk them being infected with cryptocurrency mining malware.

Someone has developed a simple Linux trojan designed to harness the meager power of Raspberry Pi devices to mine cryptocurrency.

Raspberry Pi users may need to consider applying a recent Raspbian OS update to their devices, particularly if they are currently configured to allow external SSH connections.

According to Russian security firm Dr Web, the malware Linux.MulDrop.14 exclusively targets Raspberry Pi devices to use their processing power to mine a cryptocurrency.

Dr Web discovered the Raspberry Pi mining malware after its Linux honeypot machine became infected with it. The malware uses a simple Bash script to attempt to connect to Raspberry Pi devices configured to accept external SSH connections. It targets Raspberry Pi boards with the default login and password, which are 'pi' and 'raspberry', respectively.

Even the strongest passwords are fallible, and as Samy Kamkar demonstrates, sometimes it doesn’t take much. Kamkar’s new exploit, PoisonTap, uses free software and a $5 Raspberry Pi Zero microcomputer. After attaching the Raspberry Pi to a USB adapter and plugging it in, the device goes to work. In all of 30 seconds, it bypasses your …
