Don’t Use Linksys Routers

cleverhacks:

multiple remote root exploits for some of Cisco’s latest consumer-grade gear – and remember, if your router is pwned, it doesn’t matter if all your computers are patched and ultra-secure; your traffic can still be silently MITM’d and your connection hijacked for nefarious purposes.

Ah…another set of router exploits. At least all the major routers that run traffic in the core of the networks are secure from these kinds of vulnerabilities because of high degrees of security-first coding, right?

The determination by Congress and President Barack Obama’s administration to protect networks of critical U.S. industries from hackers and cyberspies is creating an explosive growth opportunity – for lobbyists.

There were 513 filings by consultants and companies to press Congress on cybersecurity by the end of 2012, up 85 percent from 2011 and almost three times as many as in 2010, according to U.S. Senate filings. Twelve firms have submitted new registrations this year on behalf of companies including Google Inc. (GOOG)’s Motorola Mobility unit, Symantec Corp. (SYMC), United Parcel Service Inc. (UPS) and Ericsson Inc., the U.S. subsidiary of Stockholm-based Telefonaktiebolaget LM Ericsson.

Eric Engleman & Jonathan D. Salant, “Cybersecurity Lobby Surges as Congress Considers New Laws

I’m sure the lobbyists are only there as good patriotic Americans, aiming to best ensure that Americans are kept safe and Congresspeople and Senators (and their associated staff) just get the best information possible. No way that, in the wake of US scaremongering, lobbyists are looking to massively expand ‘security’ projects to the detriment of Americans’ privacy and (almost comically) security interest. Right?

An often-overlooked dimension of cyber espionage is the targeting of civil society actors. NGOs, exile organizations, political movements, and other public interest coalitions have for many years encountered serious and persistent cyber assaults. Such threats — politically motivated and often with strong links to authoritarian regimes — include website defacements, denial-of-service attacks, targeted malware attacks, and cyber espionage. For every Fortune 500 company that’s breached, for every blueprint or confidential trade secret stolen, it’s a safe bet that at least one NGO or activist has been compromised in a similar fashion, with highly sensitive information such as networks of contacts exfiltrated. Yet civil society entities typically lack the resources of large industry players to defend against or mitigate such threats; you won’t see them hiring information security companies like Mandiant to conduct expensive investigations. Nor will you likely see Mandiant paying much attention to their concerns, either: if antivirus companies do encounter attacks related to civil society groups, they may simply discard that information as there is no revenue in it.

What Sophisticated Security Tests Should Look Like

Facebook and a few other large corporations understand just how serious contemporary data intrusions and exfiltrations are. They spend a lot of money preparing for attacks. Why, if private companies, are taking collected data so seriously do our governments seem to remain so cavalier with their data collection, retention, and security practices?

Packets of Death

cleverhacks:

very nice detective work, in which we discover that a single ill-favored packet can completely kill certain Intel gigabit NICs (to the point that a power cycle is required to resurrect them). Excellent writeup (and I discovered a new tool: open source packet generation suite Ostinato, which aims to be “wireshark in reverse”).

The significance, via Slashdot: “With a modified HTTP server configured to generate the data at byte value (based on headers, host, etc) you could easily configure an HTTP 200 response to contain the packet of death and kill client machines behind firewalls!”

It’s not good to be on Power’s bad side, however. When you are on that side, Power piles on charges rather than shrugging off felonies as simple mistakes. Especially if what you do falls into the gray area of enforcing the letter as opposed to the principles of the law.

You can file all the petitions you like with the powers that be. You can try to make Power –whether in the form of wiretapping without warrants or violating international conventions against torture — follow its own laws. But Power is, as you might suspect, on the side of Power. Which is to say, Power never pleads guilty.

Could Email Undermine the 2012 American Election?

In the aftermath of Hurricane Sandy, some of the polling stations that would have been used by Americans to cast ballots are gone. Moreover, some citizens in New Jersey are unlikely to either find their new polling station or take the time to find a station and vote. Quite simply, they’re rebuilding their lives: presidential politics aren’t necessarily centre of mind at the moment.

In the wake of the disaster, New Jersey will let some voters cast their ballots by fax and email. One American expert has identified a range of possible attack vectors that could be used to compromise people’s votes. He’s quoted as saying,

Those are just some of the more obvious and potentially catastrophic ways a direct security failure could affect this election … The email voting scheme has so many ways it can fail or that doubt can be cast on the integrity of the results, that if a race somewhere in New Jersey is decided by email ballots, it seems almost guaranteed that we’re going to have a bunch of mini-2000-in-Floridas all over the state.

In addition to basic security concerns around voting, it’s critical to understand that voting by email (effectively) removes secrecy provisions. Messages will not have to be encrypted, meaning that if employees cast their ballots at work then their employer(s) could ascertain how their employees are voting. This is an incredibly serious issue.

In the best of worlds, the New Jersey elections won’t rely or depend on the emailed votes to determine a winner. This said, even if the votes don’t change the local results – if individuals win seats by sufficient margins that the emailed ‘ballots’ wouldn’t affect who won – the national vote could the endangered if the New Jersey voting system is connected to the national system. The risk, here, is that if an attacker could compromise the New Jersey voting infrastructure (perhaps by sending an infected attachment to an email message) then the rest of the infrastructure could also be compromised. Such an attack, were it to occur, could compromise not just the New Jersey results but, potentially, races across the United States.

While it’s evident why the government decided to let people vote by email – to ensure that Americans could cast their ballot despite the horrific natural disaster – these good intentions could result in very, very bad results. Worse, it could encourage trust and confidence in online voting systems more generally, systems that simply cannot be adequately secured (for more as to why, see this and this). While paper ballets are infuriating for many they remain an ideal means of confidently expressing voting intentions. While alternate approaches certainly need to be considered to let people vote, especially in times of crisis, voting by email is not an idea that should have been contemplated, let alone adopted, as a solution to the Sandy-related voting problems.

Major Critical Infrastructure Vulnerabilities Disclosed

For years, researchers have warned that the systems that run critical infrastructure have systemic and serious code-based vulnerabilities. Unfortunately, governments have tended to use such warnings as a platform to raise ‘cyber-warfare’ arguments. Many such arguments are thinly-disguised efforts to assert more substantive government surveillance and control over citizens’ rights and expressions of freedom. Few of these arguments genuinely address the concerns researchers raise.

In the face of governmental lacklustre efforts to secure infrastructure, researchers have disclosed critical vulnerabilities in many of the systems responsible for manufacturing facilities, water and waste management plants, oil and gas refineries and pipelines, and chemical production plants. What’s incredibly depressing is this:

The exploits take advantage of the fact that the Modicon Quantum PLC doesn’t require a computer that is communicating with it to authenticate itself or any commands it sends to the PLC—essentially trusting any computer that can talk to the PLC. Without such protection, an unauthorized party with network access can send the device malicious commands to seize control of it, or simply send a “stop” command to halt the system from operating.

These kinds of ‘attacks’ or ‘exploits’ are possible because the most basic security precautions are not integrated into the logic controllers running such infrastructure. On the one hand this makes sense: many PLCs and the infrastructure they are embedded in were created and deployed prior to ‘the Internet’ being what it is today. On the other, however, one has to ask: if the money spent on security theatre at airports had been invested in hardening actual PLCs and other infrastructure, where would critical infrastructure security be today?

Surprise: American Equipment Spies on Iranians

Steve Stecklow, for Reuters, has an special report discussing how Chinese vendor ZTE was able to resell American network infrastructure and surveillance products to the Iranian government. The equipment sold is significant;

Mahmoud Tadjallimehr, a former telecommunications project manager in Iran who has worked for major European and Chinese equipment makers, said the ZTE system supplied to TCI was “country-wide” and was “far more capable of monitoring citizens than I have ever seen in other equipment” sold by other companies to Iran. He said its capabilities included being able “to locate users, intercept their voice, text messaging … emails, chat conversations or web access.”

The ZTE-TCI documents also disclose a backdoor way Iran apparently obtains U.S. technology despite a longtime American ban on non-humanitarian sales to Iran – by purchasing them through a Chinese company.

ZTE’s 907-page “Packing List,” dated July 24, 2011, includes hardware and software products from some of America’s best-known tech companies, including Microsoft Corp, Hewlett-Packard Co, Oracle Corp, Cisco Systems Inc, Dell Inc, Juniper Networks Inc and Symantec Corp.

ZTE has partnerships with some of the U.S. firms. In interviews, all of the companies said they had no knowledge of the TCI deal. Several – including HP, Dell, Cisco and Juniper – said in statements they were launching internal investigations after learning about the contract from Reuters.

The sale of Western networking and surveillance equipment/software to the Iranian government isn’t new. In the past, corporate agents for major networking firms explained to me the means by which Iran is successfully importing the equipment; while firms cannot positively know that this is going on, it’s typically because of an intentional willingness to ignore what they strongly suspect is happening. Regardless, the actual sale of this specific equipment – while significant – isn’t the story that Western citizens can do a lot to change at this point.

Really, we should be asking: do we, as citizens of Western nations, believe that manufacturing of these kinds of equipment is permissible? While some degree of surveillance capacity is arguably needed for lawful purposes within a democracy it is theoretically possible to design devices such that they have limited intercept and analysis capability out of the box. In essence, we could demand that certain degrees of friction are baked into the surveillance equipment that is developed, and actively work to prevent companies from producing highly scaleable and multifunctional surveillance equipment and software. Going forward, this could prevent the next sale of significant surveillance equipment to Iran on grounds that the West simply doesn’t have any for (legal) sale.

In the case of government surveillance inefficiency and lack of scaleability are advantageous insofar as they hinder governmental surveillance capabilities. Limited equipment would add time and resources to surveillance-driven operations, and thus demand a greater general intent to conduct surveillance than when authorities have access to easy-to-use, advanced and scalable, surveillance systems.

Legal frameworks are insufficient to protect citizens’ rights and privacy, as has been demonstrated time and time again by governmental extensions or exploitations of legal frameworks. We need a normatively informed limitation of surveillance equipment that is included in the equipment at the vendor-level. Anything less will only legitimize, rather than truly work towards stopping, the spread of surveillance equipment that is used to monitor citizens across the globe.
