Update: Serial Server Flaws Expose Critical Infrastructure

A survey conducted by the firm Rapid 7 has found evidence that widespread vulnerabilities and insecure configuration of ubiquitous networking components known as serial port (or “terminal”) servers, may expose a wide range of companies and critical assets – including point of sale terminals, ATMs and industrial control systems – to remote cyber attacks.(*) The vulnerable devices connected hardware like retail point-of-sale systems at a national chain of dry cleaners, providing direct access to employee terminals from which customer payment information could be accessed. Other exposed systems were used to monitor the location of cargo containers, train cargo as well as HVAC and industrial control systems, Rapid7 said. In the Rapid7 survey, over 114,000 unique IPs were identified in a scan using the Simple Network Management Protocol (SNMP), the vast majority manufactured by one company: Digi International. If left unaddressed, the vulnerable devices give remote attackers direct, administrative access to hardware devices […]

Welcoming A New Sponsor: The Trusted Computing Group!

The Security Ledger is a new, online publication that’s serious about reporting on security and “The Internet of Things.” While we’ve had tremendous success in our first six months of operation, any new endeavor involves some risk. That’s why I’m thrilled to have had the backing of some forward-looking sponsors: Qualys and Veracode. And today, I’m happy to add a new name to that list: The Trusted Computing Group (TCG). For those of you who aren’t familiar with TCG, its best known as the group behind the Trusted Platform Module (TPM) secure, cryptographic chip that ships with almost every modern desktop and notebook PC. The TPM assures a hardware-based root of trust on compliant system, allowing TPM-equipped systems to securely generate cryptographic keys that can authenticate each endpont for use in secure, online transactions and communications. But TCG actually does a lot more. As a security beat reporter, for example, I […]

Botnet Of Embedded Devices Used To Map Internet

Botnets are mostly linked with spam e-mail campaigns, denial of service attacks and data theft. But global networks of compromised hosts can be used for a variety of ends – not all of them malicious. That was the idea behind “Internet Census 2012,” a stealth project by an unnamed and unknown researcher/hacker to map the entire IPV4 Internet address space using a massive network of compromised devices. The results, published in the form of a research paper, underscore the problem of  unsecured embedded devices, including set top boxes, home routers and critical infrastructure, with the hacker able to locate and compromise these systems, creating a botnet of more than 420,000 nodes. According to a copy of the report, the project grew out of an experiment to locate unprotected devices online using nmap, the open source scanning tool. By compromising each vulnerable host and then enlisting it to scan for other […]

Bluetooth-Sniffing Highway Traffic Monitors Vulnerable to MITM Attack

A system that monitors traffic patterns by pinging Bluetooth devices carried within passing automobiles is vulnerable to man in the middle attacks that could allow a remote attacker to steal data or remotely control or disable systems used to monitor freeways across the U.S., according to an alert from the Department of Homeland Security’s Industrial Control System Computer Emergency Readiness Team (ICS-CERT). ICS-CERT issued an advisory on Friday for customers who use Bluetooth-based traffic systems from the firm Post Oak Traffic Systems. Post Oak’s AWAM Bluetooth Reader Traffic Systems do not properly generate authentication keys used to secure communications. That could allow an attacker to calculate the private key used by the AWAM reader, then use those to impersonate the device, siphoning off administrative credentials that would give them direct access to the traffic monitoring system, DHS warned. Post Oak’s Anonymous Wireless Address Matching (AWAM) devices are installed at the […]

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 […]
