Punch Out: Security Holes In Time Clock Bite TSA, Others

A common time clock that is used by companies and government agencies, including the Transportation Security Administration (TSA) contains pre-programmed “back door” user accounts that could allow malicious attackers to gain access to sensitive networks, according to research by a security researcher at Qualys Inc. Speaking before an audience at the Black Hat Briefings in Las Vegas on Wednesday, Billy Rios, the Director of Threat Intelligence at Qualys Inc., revealed research on the Kronos 4500, a “time and attendance” product (aka time clock) that employees use to ‘punch in’ and ‘punch out’ from work. Rios said that an in-depth analysis of the Kronos equipment and the software that it runs revealed two types of backdoor accounts (user names and passwords) that will provide access to any deployed 4500 device. The accounts are particularly worrying because some vulnerable devices can be discovered using Internet searches, and because TSA is known to use Kronos attendance […]

DHS Warns Energy Firms Of Malware Used In Targeted Attacks

The Department of Homeland Security warned firms in the energy sector about new, targeted malware infecting industrial control systems and stealing data. DHS’s ICS CERT, the Industrial Control Systems Computer Emergency Response Team, said it is analyzing malware associated with an ICS-focused malware campaign. The malicious software, dubbed “Havex” that was being spread by way of phishing emails and so-called “watering hole” attacks that involved compromises of ICS vendor web sites. DHS was alerted to the attacks by researchers at the security firms Symantec (which dubbed the malware campaign “Dragonfly”) and F-Secure (“Havex”) -a remote access trojan (or RAT) that also acts as an installer (or “downloader”) – fetching other malicious applications to perform specific tasks on compromised networks. One of those additional payloads is a Trojan Horse program dubbed Karagany (by Symantec) that has been liked to prior attacks on energy firms. According to Symantec, the malware targeted energy grid operators, major electricity generation firms, […]

Is Analog The Answer To Cyber Terrorism?

Ralph Langner is one of the foremost experts on the security of critical infrastructure that we have. So, generally, when Ralph says something – whether its about Stuxnet, or cyberwar or the security of nuclear power plants – folks listen. And these days, Ralph is wondering, out loud, whether our reliance on digital systems to manage critical infrastructure has gone too far. The answer, he suggests, may be to go “back to the future,” as it were: reintroducing analog systems into the control process chain as a backstop for cyber attacks. Case in point: the Department of Homeland Security’s ICS-CERT warned on Friday that firmware for Siemens SIMATIC S7-1500 CPUs (Central Processing Units) contain nine vulnerabilities that could enable attacks such as cross site request forgery, cross site scripting and URL redirection. (Siemens has issued a firmware update that patches the holes.) Langner is among the world’s foremost experts on […]

Experts: Despite Warnings, Slow Progress Securing Industrial Systems

Despite increased media attention to the security of industrial control systems and critical infrastructure, progress in securing those devices has been slow, experts say. Despite progress in some areas, critical infrastructure – including energy and transportation networks- remains vulnerable to attacks leveled at known security holes for months or years because of a lack of vendor response or customers who lack the incentive or know-how to patch vulnerable systems. That according to some of the world’s top experts in cyber security and industrial systems, who are gathering this week at an industry conference in Miami. The S4 Conference, sponsored by the firm DigitalBond, is one of the premiere conferences for cyber security as it pertains to industrial control systems and often coincides with disclosures from industrial system vendors about serious security holes in their products. The security of industrial control systems has been a top concern of IT security experts and government […]

Zombies Gone, Problems Persist With Emergency Alert System

More than six months after hacked Emergency Alert System (EAS) hardware allowed a phony warning about a zombie uprising to air in several U.S. states, a security consulting company is warning that serious issues persist in software from Monroe Electronics, whose equipment was compromised in the earlier attack. Software updates issued by Monroe to fix security problems with earlier versions of its software have introduced serious, new issues that could once again allow EAS devices to be compromised by a remote hacker, according to a post by Mike Davis, a researcher at the security firm IOActive on Thursday. Patches issued by Monroe Electronics, the Lyndonville, New York firm that is a leading supplier of EAS hardware, do not adequately address problems raised by Davis and others earlier this year, including the use of “bad and predictable” login credentials. Further inspection by Davis turned up other problems that were either missed […]
