Last week, the imageboard site 8chan.co was brought offline for a sustained period of over five days due to a prolonged DDoS attack. On Monday, it returned only to go back offline for a much different reason: Its domain had been seized.
Site founder Fredrick Brennan posted an e-mail on Monday that he says came from the site's Bahamas-based registar, Internet.bs. The note explained that the domain 8chan.co had been put "on hold" due to "child abuse" content appearing on the site.
This followed a swell of complaint e-mails sent over the weekend to Cloudflare, the "pass-through" content delivery network that had been operating 8chan's servers. Some users were upset over content posted on 8chan by its imageboard users and directed their complaints to Cloudflare. "Please take appropriate measures to stop your customer from abusing your services and enabling illegal content," one complainant wrote after posting links to 11 8chan boards that contained underage "girls and boys shown in sexual poses."
Thanks to our reader David for sending us this detect (anonymized):

Davids web server was hit with a sufficient number of requests like the one above to cause a denial of service. The requests originated from thousands of different IP addresses, all appear to be located in China. A quick Google search revealed that he wasnt alone, but other web servers experienced similar attacks.
Given the host header (and David observed various thepriatebay.org host names), it looks like some DNS servers responded with Davids IP address if queried for thepiratebay.org.
I did a quick check of passive DNS systems, and didnt find Davids IP. But when I queried Chinese DNS servers for the host name, I recieved numerous answers. Each answer was only repeated a couple times, if at all. It sort of looked like they all returned different IP addresses. US based DNS servers on the other hand usually dont resolve the host name, or respond with 127.0.0.1, a typical blacklisting technique. Only a handful responded with a routable IP address.
Overall, I am not sure what is happening. Looks like a Chinese firewall issue to me. But if you have any ideas or packets, please let me know.

A security researcher examining the website of North Korea's official news service, the Korean Central News Agency, has discovered that the site delivers more than just the latest photo spread of Democratic Peoples' Republic of Korea leader Kim Jong Un inspecting mushroom farms. There's a little extra surprise hidden in the site's code—malware. The news site appears to double as a way for North Korea to deliver a "watering hole" attack against individuals who want to keep tabs on the "activities" of the DPRK's dear leader.
The perennial problem of bug disclosure has provoked a new squabble between Microsoft and Google. On Sunday, Google disclosed the existence of a Windows elevation of privilege flaw that the company reported privately in October. That flaw hasn't been patched yet. It will be very soon—the update is due to land on Patch Tuesday, tomorrow—but Google's publication of the flaw means that, for a couple of days, Windows users are vulnerable to an unfixed flaw.
In response, Chris Betz, senior director of the Microsoft Security Response Center, published a lengthy complaint calling for "better coordinated vulnerability disclosure."
Microsoft has been promoting "coordinated vulnerability disclosure" since 2010, but the security community has long been split on how best to disclose security flaws. On one extreme is the full disclosure crowd; security flaws are documented and described in full, in public, typically onto a mailing list. In the early days, that disclosure was typically the first time the software developer responsible even heard of the flaw, though some researchers promised to disclose to vendors first.
Thousands of articles have called the December attack against Sony Pictures a wake-up call to industry. Regardless of whether the attacker was the North Korean government, a disgruntled former employee, or a group of random hackers, the attack showed how vulnerable a large organization can be and how devastating the publication of its private correspondence, proprietary data, and intellectual property can be.
But while companies are supposed to learn that they need to improve their security against attack, there's another equally important but much less discussed lesson here: companies should have an aggressive deletion policy.
One of the social trends of the computerization of our business and social communications tools is the loss of the ephemeral. Things we used to say in person or on the phone we now say in e-mail, by text message, or on social networking platforms. Memos we used to read and then throw away now remain in our digital archives. Big data initiatives mean that we're saving everything we can about our customers on the remote chance that it might be useful later.
The Twitter and YouTube accounts belonging to the US Central Command were compromised on Monday by people who claimed they hacked sensitive US military PCs and leaked confidential material in support of the Islamic State.
The compromised CENTCOM Twitter account contained graphics and text supporting the Islamic State in Iraq and Syria (ISIS), and it warned the US to expect more hacks. It was carried out by a person or group dubbed the CyberCaliphate. Central Command is one of nine unified commands in the US military. With its area of responsibility covering Afghanistan, Iraq, Syria, and Iran, it leads the US campaign against Islamic State extremists. Monday's attacks appeared to be carried out by the same group that earlier this month commandeered the Twitter accounts of CBS affiliate WBOC-TV and the Albuquerque Journal.
At the time this post was being prepared, there was conflicting evidence supporting the claim that anything more than CENTCOM's Twitter and YouTube accounts were compromised. Files linked in a post on Pastebin contained what appeared to be rosters of US military personnel, including contact information for Army commands and retired Army generals. A separate series of documents, contained in a folder titled war-scenarios, showed PowerPoint slides that appeared to be related to war games exercises involving China, North Korea, and regions in Africa, Indonesia, and the Caspian. One slide in a file titled SOCOM_Africa_Scenario.ppt was dated January 12, 2015. It proposed a CIA operation in Congo and Southern Africa dubbed "Operation Cakewalk" to seize yellowcake uranium. CENTCOM officials confirmed the compromise of the social networking accounts but told CNN none of the leaked documents appeared to be classified.

Our houses and offices are more and more infested by electronic devices embedding a real computer with anoperating system and storage. They areconnected to network resources for remote management, statistics or datapolling. This is called the Internet of Things or IoT. My home network ishardened and any new (unknown)device connected to it receives an IP address from a specific range which has no connectivity with other hosts or theInternet but its packets are logged. The goal is to detect suspicious activity like data leaks or unexpected firmwareupdates. The last toy I boughtyesterday is aSmart Plugfrom Supra-Electronics. This device allows you to control apower plug via your mobile device and calculate the energyconsumption with nice stats. I had a very goodopportunity to buy one for a very low price (25). Lets see whats inside....
The documentation mentions a setup procedure and management via a mobile device (with a free app for IOS orAndroid) but the first reflex is to scan the box. Interesting, a webserver as well as a telnet server are waiting forpackets. Lets try common credentials like admin/admin and...

Immediately after the boot sequence, the device started to try to communicate with remote hosts:
Amongst DNS requests and NTP synchronization, a lot of traffic was generated to different IP addresses overUDP/10001. The same packet being sent to different hosts. The payload was a block of 60 bytes:
I was not able to decode the content of this payload, please comment if you recognize some patterns. The devicealso performs a regular connectivity check via a single ICMP ECHO packet sent towww.google.com(every 5 mins).This network traffic is generated by the process called RDTServer:

In fact, theIOTC platformis a service developed by ThoughTek to establish P2P communications between devices.I read the documentation provided with the device as well as all the website pages and there is no mention of thisservice. Manufacturers should include some technical documentation about the network requirements (ex: todownload firmware updates). In this case, its not a major security issue but this story enforces what we alreadyknow (and be afraid) about IoT: those devices have weak configuration and they lack of visibility/documentationabout their behavior. Take care when connecting them on your network. A best practice is to inspect the traffic theygenerate once online (DNS requests, HTTP(S) request or any other protocol).
