Global Cyber Attack Halted: Autopsy Time

Friday saw what looked like the most dangerous ransomware infection to date. The infection known as WannaCry was closing down vital hospital IT systems across the UK canceling major operations and putting lives at risk.

Spread Halted?

It spread further around the world and almost became a global pandemic. Although machines are still encrypted demanding Bitcoin, one security blogger [MalwareTech] halted the ransomware by accident. As he was analyzing the code he noticed that the malware kept trying to connect to an unregistered domain name “iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com”. So he decided to register the domain to see if he could get some …read more

White-hat Botnet Infects, Then Secures IoT Devices

[Symantec] Reports Hajime seems to be a white hat worm that spreads over telnet in order to secure IoT devices instead of actually doing anything malicious.

[Brian Benchoff] wrote a great article about the Hajime Worm just as the story broke when first discovered back in October last year. At the time, it looked like the beginnings of a malicious IoT botnet out to cause some DDoS trouble. In a crazy turn of events, it now seems that the worm is actually securing devices affected by another major IoT botnet, dubbed Mirai, which has been launching DDoS attacks. More recently …read more

ArduWorm: A Malware for Your Arduino Yun

We’ve been waiting for this one. A worm was written for the Internet-connected Arduino Yun that gets in through a memory corruption exploit in the ATmega32u4 that’s used as the serial bridge. The paper (as PDF) is a bit technical, but if you’re interested, it’s a great read.

The crux of the hack is getting the AVR to run out of RAM, which more than a few of us have done accidentally from time to time. Here, the hackers write more and more data into memory until they end up writing into the heap, where data that’s used to control …read more
