SCADA systems ICS-CERT alert issued...
- http://threatpost.co...-systems-110210
November 2, 2010 - "ICS-CERT, the emergency response team for industrial control systems, has warned companies that run SCADA (Supervisory Control and Data Acquisition) software that the systems running it may be easily discovered using a free Web based search engine dubbed Shodan. The warning came in the form of an ICS-CERT Alert*, published on October 28. The group, which is part of US-CERT, warns that "multiple independent security researchers" have reported using SHODAN to discover Internet facing SCADA systems in "several critical infrastructure sectors". The systems discovered range from systems used for remote access and monitoring, but also include systems with the ability to directly manage configuration of SCADA systems... Control system operators were advised to conduct an audit their existing systems, including those not directly connected to the Internet, to make sure that no weak or default passwords are being used. In addition, operators are advised to place any control systems behind firewalls and to isolate them from business networks. Virtual Private Networks (VPN) should be used for remote access to such systems and strong passwords and access management strategies should be employed..."

SCADA/Siemens vuln detail remains in fog...
- http://www.csoonline...a-security-talk
May 23, 2011 - "After a presentation on SCADA (supervisory control and data acquisition) system exploits was pulled at the last minute from the TakeDownCon conference, accusations began to swirl that NSS Labs, the company that helped fund the research, had been told by the Department of Homeland Security (DHS) to pull the talk that would have exposed existing flaws in certain Siemens systems used to control critical infrastructure... Vik Phatak, chief technology officer at NSS Labs. "Siemens found out, near the last minute, that the mitigation they had planned didn't work. It could be bypassed," Phatak says. According to Phatak, DHS pointed to a broad context of risks should the talk go forward without proper mitigation. Following that, NSS Labs independently chose to postpone the talk... Siemens and DHS ICS CERT are expected to release advisories and fixes for the vulnerabilities within the week, Phatak said..."

ICS-Siemens patches released...

June 10, 2011 - "Siemens has fixed bugs in its Simatic S7 industrial computer systems, used to control machines on factory floors, power stations and chemical plants. The patches*, released Friday, mark Siemens' first response to a high-profile computer security incident since the Stuxnet worm, which was discovered a year ago circulating on computer networks in Iran. Siemens fixed a pair of flaws in the S7-1200 controller, acknowledging that one could be leveraged to take control of the system using what's known as a replay attack. A second flaw, in a Web server that ships with the device, could give attackers a way to crash the system. However, the attacker would have to first find a way onto the victim's network before launching these attacks..."

Stuxnet2 - follow-up for SCADA systems - "DuQu"
- https://isc.sans.edu...l?storyid=11836
Last Updated: 2011-10-19 01:36:37 UTC - "... Symantec, McAfee and F-Secure*, to name a few security vendors, released information about what they are calling "DuQu"... because this malware creates some files on the user's temp folder, that starts with ~DQXXX.tmp (where the XXX can be any number)... There are several common aspects between DuQu and Stuxnet that leads to the conclusion that they were written by the same group. While the original Stuxnet was focused on Industrial systems, aka SCADA, this DuQu malware is mostly used on a recon process, and being used as an advanced RAT (Remote Administration Tool)... DuQu received commands via an encrypted config file, and seems to download a password stealer that is able to record several behaviors from user and machine and send to a Command and Control IP in India. Like some of the components of the original Stuxnet, this one was also able to decrypt and extract additional components embedded into other PE files... like Stuxnet, some components had a VALID digital signature..."

India "Duqu" server components confiscated

Two workers at a web-hosting company called Web Werks told Reuters that officials from India's Department of Information Technology last week took several hard drives and other components from a server that security firm Symantec Corp told them was communicating with computers infected with Duqu... The equipment seized from Web Werks, a privately held company in Mumbai with about 200 employees, might hold valuable data to help investigators determine who built Duqu and how it can be used...

However, organizations should still remain vigilant against this and other sophisticated malware. ICS-CERT also recommends that the ICS community update intrusion prevention systems (IPSs) and antivirus systems to detect Duqu and other new threats.

“There is no evidence to support claims made in the initial Fusion Center report – which was based on raw, unconfirmed data and subsequently leaked to the media – that any credentials were stolen, or that the vendor was involved in any malicious activity that led to a pump failure at the water plant,” the ICS-CERT alert states. “In addition, DHS and FBI have concluded that there was no malicious or unauthorized traffic from Russia or any foreign entities, as previously reported.
