Internet Worm Targets SCADA

Stuxnet is a new Internet worm that specifically targets Siemens WinCC SCADA systems: used to control production at industrial plants such as oil rigs, refineries, electronics production, and so on. The worm seems to uploads plant info (schematics and production information) to an external website. Moreover, owners of these SCADA systems cannot change the default password because it would cause the software to break down.

Automobile Security Analysis

Experimental Security Analysis of a Modern Automobile,” by a whole mess of authors:

Abstract: Modern automobiles are no longer mere mechanical devices; they are pervasively monitored and controlled by dozens of digital computers coordinated via internal vehicular networks. While this transformation has driven major advancements in efficiency and safety, it has also introduced a range of new potential risks. In this paper we experimentally evaluate these issues on a modern automobile and demonstrate the fragility of the underlying system structure. We demonstrate that an attacker who is able to infiltrate virtually any Electronic Control Unit (ECU) can leverage this ability to completely circumvent a broad array of safety-critical systems. Over a range of experiments, both in the lab and in road tests, we demonstrate the ability to adversarially control a wide range of automotive functions and completely ignore driver input—including disabling the brakes, selectively braking individual wheels on demand, stopping the engine, and so on. We find that it is possible to bypass rudimentary network security protections within the car, such as maliciously bridging between our car’s two internal subnets. We also present composite attacks that leverage individual weaknesses, including an attack that embeds malicious code in a car’s telematics unit and that will completely erase any evidence of its presence after a crash. Looking forward, we discuss the complex challenges in addressing these vulnerabilities while considering the existing automotive ecosystem.

New Windows Attack

It’s still only in the lab, but nothing detects it right now:

The attack is a clever “bait-and-switch” style move. Harmless code is passed to the security software for scanning, but as soon as it’s given the green light, it’s swapped for the malicious code. The attack works even more reliably on multi-core systems because one thread doesn’t keep an eye on other threads that are running simultaneously, making the switch easier.

The attack, called KHOBE (Kernel HOok Bypassing Engine), leverages a Windows module called the System Service Descriptor Table, or SSDT, which is hooked up to the Windows kernel. Unfortunately, SSDT is utilized by antivirus software.

Back Door in Battery Charger

Amazing:

The United States Computer Emergency Response Team (US-CERT) has warned that the software included in the Energizer DUO USB battery charger contains a backdoor that allows unauthorized remote system access.

That’s actually misleading. Even though the charger is an USB device, it does not contain the harmful installer described in the article—it has no storage capacity. The software has to be downloaded from the Energizer website, and the software is only used to monitor the progress of the charge. The software is not needed for the device to function properly.

Here are details.

Energizer has announced it will pull the software from its website, and also will stop selling the device.

EDITED TO ADD (3/23): Additional news here.

Cyber Shockwave Test

There was a big U.S. cyberattack exercise this week. We didn’t do so well:

In a press release issued today, the Bipartisan Policy Center (BPC)—which organized “Cyber Shockwave” using a group of former government officials and computer simulations—concluded the U.S is “unprepared for cyber threats.”

[…]

…the U.S. defenders had difficulty identifying the source of the simulated attack, which in turn made it difficult to take action.

“During the exercise, a server hosting the attack appeared to be based in Russia,” said one report. “However, the developer of the malware program was actually in the Sudan. Ultimately, the source of the attack remained unclear during the event.”

The simulation envisioned an attack that unfolds during a single day in July 2011. When the council convenes to face this crisis, 20 million of the nation’s smartphones have already stopped working. The attack—the result of a malware program that had been planted in phones months earlier through a popular “March Madness” basketball bracket application—disrupts mobile service for millions. The attack escalates, shutting down an electronic energy trading platform and crippling the power grid on the Eastern seaboard.

This is, I think, an eyewitness report.
