In Iran, New Data Wiping Malware on the Loose

Iran’s Computer Emergency Response Team (IR-CERT) issued a warning on Sunday about a newly discovered malicious program that is erasing hard drives on infected systems in that country – just the latest data-destroying malware to appear there. IR-CERT said that an investigation by its Maher center found that the malware “wipes files on different drives in various predefined times,” including disk partitions and user profiles. However, the malware isn’t widespread and doesn’t appear linked to “other sophisticated targeted attacks,” the alert said – in a possible reference to the Stuxnet and Flame malware, both of which targeted Iranian critical infrastructure. Subsequent analysis by independent security firms confirmed most of the details of the IR-CERT warning. Writing on Monday, Jamie Blasco of the firm Alien Vault said the malware was “just another wiping malware” and “very simple,” and could have been delivered in a variety of ways – from USB drive […]

FBI Issued Alert over July Attack on HVAC System

The FBI issued an alert to businesses in July after unknown attackers breached a computer used to control the heating, ventilation and air conditioning (HVAC) system of a New Jersey company, accessing a graphical user interface for the system, including a floor play layout of the company’s office. The attacks came after an Anonymous affiliated hacker, using the handle @ntisec, published links to vulnerable ICS systems running software from the firm Tridium online. The links included the address of an administrative system that controlled the HVAC system used by US Business 1, a New Jersey company that installs air conditioning systems for other companies, according to a copy of the July, 2012 Situational Information Report (PDF), issued by the Newark Division of the FBI. The alert concerning the February and March, 2012 attack was released by the web site Public Intelligence on Saturday. The FBI did not respond to a request for comment from Security […]

Report Warns of Growing ‘Dark Side’ of Cyberspace

The head of a prominent human rights groups has warned that increased state involvement in cyberspace, including surveillance, censorship, propaganda campaigns and offensive cyber operations threatens the future of the Internet as much as endemic problems like cyber crime – part of a growing “dark side” to cyberspace. Writing in the Penn State Journal of Law and International Affairs,  Ronald Deibert, Director of Citizen Lab and Canada Centre for Global Security Studies said that threats to human rights and individual liberties come from a variety of states – from authoritarian regimes, to Latin American narco-states to liberal democracies in the West, as governments increasingly leverage the power of the Internet to monitor citizens’ behavior and impose limits on free expression. Citizen Lab, part of the Munk School of Global Affairs at the University of Toronto, has played a key role in high-profile investigations of cyber espionage including the now-infamous Ghost Net attacks on […]

Update: New 25 GPU Monster Devours Passwords In Seconds

Editor’s note: I’ve updated the article with some new (and in some cases) clarifying detail from Jeremi. I’ve left changes in where they were made. The biggest changes: 1) an updated link to slides 2) clarifying that VCL refers to Virtual OpenCL and 3)  that the quote regarding 14char passwords falling in 6 minutes was for LM encrypted – not NTLM encrypted passwords. Long (8 char) NTLM passwords would take much longer…around 5.5 hours. 😉  – Paul There needs to be some kind of Moore’s law analog to capture the tremendous advances in the speed of password cracking operations. Just within the last five years, there’s been an explosion in innovation in this ancient art, as researchers have realized that they can harness specialized silicon and cloud based computing pools to quickly and efficiently break passwords. A presentation at the Passwords^12 Conference in Oslo, Norway (slides available here – PDF), has […]

Support Forums Reveal Soft Underbelly of Critical Infrastructure

We hear a lot about vulnerabilities in industrial control system (ICS) software. In fact, that’s all we seem to hear about these days. The truth is: there’s a lot to write about. In just the last month, the Department of Homeland Security’s ICS-CERT warned its members about the ability of  sophisticated – and even unskilled – attackers to use tools like the Shodan and ERIPP search engines to locate and attack vulnerable industrial control systems (PDF) that are accessible from the public Internet. In the meantime, every couple of weeks brings revelations about serious and remotely exploitable software holes. Most recently, ICS-CERT warned about a critical vulnerability EOScada (PDF), a Windows-based Energy Management System that is used to configure and manage intelligent electronic devices (IEDs) used in electrical, water, sewage and gas applications. But what about real evidence of compromised SCADA and industrial control systems? That’s a taller order. After all: most […]
