Ikea recently launched their Trådfri smart lighting platform in the US. The idea of Ikea plus internet security together at last seems like a pretty terrible one, but having taken a look it's surprisingly competent. Hardware-wise, the device is pretty minimal - it seems to be based on the Cypress WICED IoT platform, with 100MBit ethernet and a Silicon Labs Zigbee chipset. It's running the Express Logic ThreadX RTOS, has no running services on any TCP ports and appears to listen on two single UDP ports. As IoT devices go, it's pleasingly minimal.

Of the many, many, many bad things about passwords, you know what the worst is? Password rules.

Concerned about the role hackers and false news might have played in the United States election, the Dutch government announced on Wednesday that all ballots in next month's elections would be counted by hand.

Journalists from Dutch TV station RTL contacted me last week and wanted to know whether the Dutch elections could be hacked. They had been tipped off that the current Dutch electoral software used weak cryptography in certain parts of its system (SHA1).

I was stunned and couldn't believe what I had just heard. Are we still relying on computers for our voting process?

I was just reading some Tweets and an associated Hackernews thread and it reminded me that, now that I've left Mozilla for a while, it's safe for me to say: antivirus software vendors are terrible; don't buy antivirus software, and uininstall it if you already have it (except, on Windows, for Microsoft's).

We have confirmed that a copy of certain user account information was stolen from the company’s network in late 2014 by what we believe is a state-sponsored actor. The account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (the vast majority with bcrypt) and, in some cases, encrypted or unencrypted security questions and answers. The ongoing investigation suggests that stolen information did not include unprotected passwords, payment card data, or bank account information; payment card data and bank account information are not stored in the system that the investigation has found to be affected. Based on the ongoing investigation, Yahoo believes that information associated with at least 500 million user accounts was stolen and the investigation has found no evidence that the state-sponsored actor is currently in Yahoo’s network. Yahoo is working closely with law enforcement on this matter.

Researchers discovered that a Transmission Control Protocol (TCP) specification implemented in Linux creates a vulnerability that can be exploited to terminate connections and conduct data injection attacks.

The flaw, tracked as CVE-2016-5696, is related to a feature described in RFC 5961, which should make it more difficult to launch off-path TCP spoofing attacks. The specification was formulated in 2010, but it has not been fully implemented in Windows, Mac OS X, and FreeBSD-based operating systems. However, the feature has been implemented in the Linux kernel since version 3.6, released in 2012.

A team of researchers from the University of California, Riverside and the U.S. Army Research Laboratory identified an attack method that allows a blind, off-path attacker to intercept TCP-based connections between two hosts on the Internet.

Researchers noted that data cannot be injected into HTTPS communications, but the connection can still be terminated using this method. One attack scenario described by the experts involves targeting Tor by disrupting connections between certain relays so that users are forced to use attacker-controlled exit relays.

Ahmed Mansoor is an internationally recognized human rights defender, based in the United Arab Emirates (UAE), and recipient of the Martin Ennals Award (sometimes referred to as a “Nobel Prize for human rights”). On August 10 and 11, 2016, Mansoor received SMS text messages on his iPhone promising “new secrets” about detainees tortured in UAE jails if he clicked on an included link. Instead of clicking, Mansoor sent the messages to Citizen Lab researchers. We recognized the links as belonging to an exploit infrastructure connected to NSO Group, an Israel-based “cyber war” company that sells Pegasus, a government-exclusive “lawful intercept” spyware product. NSO Group is reportedly owned by an American venture capital firm, Francisco Partners Management.

The ensuing investigation, a collaboration between researchers from Citizen Lab and from Lookout Security, determined that the links led to a chain of zero-day exploits (“zero-days”) that would have remotely jailbroken Mansoor’s stock iPhone 6 and installed sophisticated spyware. We are calling this exploit chain Trident. Once infected, Mansoor’s phone would have become a digital spy in his pocket, capable of employing his iPhone’s camera and microphone to snoop on activity in the vicinity of the device, recording his WhatsApp and Viber calls, logging messages sent in mobile chat apps, and tracking his movements.

Symantec and Norton are among the most popular security tools, but the U.S. Department of Homeland Security warns of critical flaws that could pose great risks.

A slew of corporate, government and personal computers are protected by Symantec, but are they really protected? Homeland Security believes there's reason to worry, and has issued a warning this week.

"Symantec and Norton branded antivirus products contain multiple vulnerabilities. Some of these products are in widespread use throughout government and industry," notes the alert. "Exploitation of these vulnerabilities could allow a remote attacker to take control of an affected system."

Let me be clear - Pokemon Go and Niantic can now:

• Read all your email
• Send email as you
• Access all your Google drive documents (including deleting them)
• Look at your search history and your Maps navigation history
• Access any private photos you may store in Google Photos
• And a whole lot more

What's more, given the use of email as an authentication mechanism (think "Forgot password" links) they now have a pretty good chance of gaining access to your accounts on other sites too.

The attack, which was targeted at US users, hit websites including the New York Times, the BBC, AOL and the NFL over the weekend. Combined, the targeted sites have traffic in the billions of visitors.

The malware was delivered through multiple ad networks, and used a number of vulnerabilities, including a recently-patched flaw in Microsoft's former Flash competitor Silverlight, which was discontinued in 2013.

Rep. Ted Lieu (D-CA) and Rep. Blake Farenthold (R-TX) are introducing a bill today to effectively override bad state-level encryption bills. The ENCRYPT Act of 2016, or by its longer name, the Ensuring National Constitutional Rights of Your Private Telecommunications Act, would preempt state and local government encryption laws. The two men said today they are "deeply concerned" that varying bills surrounding encryption would endanger the country as well as the competitiveness of American companies. The argument is that it wouldn't be easy or even feasible to tailor phone encryption capabilities for specific states.

On Thursday, tech giant Juniper Networks revealed in a startling announcement that it had found "unauthorized" code embedded in an operating system running on some of its firewalls.

The code, which appears to have been in multiple versions of the company's ScreenOS software going back to at least August 2012, would have allowed attackers to take complete control of Juniper NetScreen firewalls running the affected software. It also would allow attackers, if they had ample resources and skills, to separately decrypt encrypted traffic running through the Virtual Private Network, or VPN, on the firewalls.

The security community is particularly alarmed because at least one of the backdoors appears to be the work of a sophisticated nation-state attacker.

Earlier this year it was revealed that Lenovo was shipping computers preloaded with software called Superfish, which installed its own HTTPS root certificate on affected computers. That in and of itself wouldn't be so bad, except Superfish's certificates all used the same private key. That meant all the affected computers were vulnerable to a "man in the middle" attack in which an attacker could use that private key to eavesdrop on users' encrypted connections to websites, and even impersonate other websites.

Now it appears that Dell has done the same thing, shipping laptops pre-installed with an HTTPS root certificate issued by Dell, known as eDellRoot. The certificate could allow malicious software or an attacker to impersonate Google, your bank, or any other website. It could also allow an attacker to install malicious code that has a valid signature, bypassing Windows security controls. The security team for the Chrome browser appears to have already revoked the certificate. People can test if their computer is affected by the bogus certificate by following this link.
