Jmurray8at March 02,2015 1. Dissecting Stuxnet – well done - Excellent
• 50KB or 50 times bigger than usual malware – probably developed by the government
• Uses 7 distinct mechanisms to spread to computers
• Attacks a hole in the windows print spooler – windows RPC service as well as a PLC
• Siemens PLC (Programmable Logic controller) database software – using a default password
• Peer-to-peer updating network – so it can update itself
• Most likely used a USB drive or a shared printer
• Stuxnet software was signed by two corporations
tristayifeiat March 12,2015 The video has a very detailed explanation of Stuxnet. Mr. Nachenberg explains the stuxnet in a simple way. It is impressed to know that Stuxnet can spread to other locations by themselves through network, hard drives, and windows RPC service, etc., even it can find the target itself and then attack it. The scary part is that it can come back to normal just within a coffee break time, and you won’t know anything. Then after sleeping of 27 days, it begins to spin, and it can repeat over and over again. I felt it is very helpful that the pictures in the video give a visual scene of the spreading and damaging. I agree with Mr. Nachenberg that setting up an alarm bell or a periodic monitoring of network and software would be helpful in detecting these virus. He also talked about the problem of authentication certifications of the authors of the virus. Borrow his word, it is “unbelievable!”
marinomsat March 26,2015 I believe that the threat of this attack is very interesting. From how it can spread from computer to computer or network to network. Also the way that it will monitor the systems and the intelligence that this has. How it is programed to wait and analyze is pretty scarey. Also the way it can hide what is really going on is pretty insane. this type of technology used on a broader topic could really do some damage to the United States.
DPerryat April 08,2015 My old nemesis.. the print spooler! This is very interesting. I could definitely get into this type of work, digitally attacking hostile nations.
Ahmedat April 15,2015 it's very inteligant peace of software/virus i like the way he explains in details how does it work and when exactly will it start functioning..Stuxnet is out there..people know about it..lets see whats next!
