The coolest hands-on cyber training opportunity (early bird deadline October 7): SANS HackFest in Washington DC in early November is packed with extra opportunities for hands-on learning and networking: 2 full days of in-depth talks from real-world hands-on experts, focused on how offense can inform defense and forensics, plus 7 great SANS immersion courses on up-to-date advanced topics. Add to that 3 nights (not the usual 2) of the NetWars Experience for students to practice the lessons they learn in class and earn up to FIVE SANS challenge coins as trophies for courses they've taken in the past. We'll even do a night of CyberCity missions for you to defend the physical model city and its critical infrastructure against nefarious attackers. We'll have a super secret field trip with a fun team-based scavenger hunt and capture the flag event for networking and further learning. And Ed Skoudis' wife will bake her world-famous cookies to share with everyone at the event. Registration and more info at http://www.sans.org/hackfest.

DHS Says Attackers Probing US States' Voting Systems (October 1 & 3, 2016)

According to a US Department of Homeland Security (DHS) official, voter registration systems in at least 20 states have been breached or probed by attackers. DHS says there is no evidence that data have been altered. However, the fact of the intrusions themselves could cause people to doubt the integrity of US voting systems.

UK's National Cyber Security Center HQ Open for Business (October 3, 2016)

The UK's National Cyber Security Centre is now open. The Centre will coordinate the UK's response to cyber threats and provide help to public and private sector organizations. The Centre's Prospectus lists four key objectives: to understand the cyber security environment and share knowledge; to help public and private sector organizations improve cyber security; to respond to cybersecurity incidents; and to foster its cyber security capability and provide leadership.


[Editor Comments ]



[Shpantzer ]
I'd like to see a national effort where one of the multiple 'centers' goes out and helps organisations implement the Top 4 of the ASD 35. Vendors could volunteer some of their software to show efficacy and reap PR rewards from 'saves' in the experiment. Who's with me?


[Paller ]
"Like" Shpantzer's idea. A national competition for who could implement the most cost-effectively would accelerate it.

Apple to Block Trust for WoSign Certificates (October 3, 2016)

Starting with its next round of updates for iOS and macOS, Apple will block trust for digital certificates issued by the WoSign CA (Certificate Authority) Free SSL Certificate G2 Intermediate CA. Last week, Mozilla announced that it would likely begin blocking WoSign certificates after learning that the CA had backdated certificates to evade SHA-1 encryption rules and that is was not forthcoming about its acquisition of StartCom.


[Editor Comments ]



[Ullrich ]
Only newly issued certificates will be blocked. If you had your certificate issued before September 19th, and if your certificate was published in a certificate transparency log, then you should be ok for now. But it is still time to move away from WoSign/StartSSL. For a free alternative, try out "letsencrypt". But if you do, realize that letsencrypt certificates are good for only 3 months and you need to automate renewals (scripts to do so are available).


[Northcutt ]
The Register article does not tell the whole story. "Trust anchors" is an important concept for white listing, (trusting) software signed by a trusted certificate authority. If a CA acts irresponsibly, the downstream impacts can be very large. Mozilla is only talking about suspending trust for a year to give WoSign time to clean up their procedures. This is not a deep technical problem, it is a procedural problem. The Schrauger article below provides more useful detail.

IoT DDoS Code Shared Online (October 2 & 3, 2016)

Source code that has been used to drive Internet of Things (IoT) botnets has been released online. Known as Mirai, the code was used in the distributed denial-of-service (DDoS) attack that targeted KrebsOnSecurity last month. Internet monitoring organizations have already noted an increase in scanning for vulnerable IoT devices.


[Editor Comments ]



[Williams ]
While the release of this code is interesting, I have already seen backdoored copies of the code repository popping up on line. Be careful before downloading and compiling this (or any other) source code for "testing" in your environment.


[Murray ]
It should not be lost in all of this that the appliances taken over in this attack are cameras. Whether one worries most about exploitation of the appliance function or the general purpose function, this should be a caution. The day may be coming when the only way to protect the community from these devices being exploited by rogues is to preemptively take them down.

Google Patches Use-After-Free Vulnerability in Chrome (September 29 & October 3, 2016)

Google's fixes for its Chrome browser include one for a use-after-free vulnerability. Last week, the Chrome stable channel was updated to version 53.0.2785.143; it is scheduled to roll out over the next few weeks. The update addresses a total of three security issues.

OpenJPEG Flaw Patched (September 29 & October 3, 2016)

Researchers at Cisco's Talos Group have found an out-of-bounds vulnerability in the OpenJPEG JPEG 2000 codec that could be exploited to allow remote code execution. The vulnerability lies in the JPEG 200 image file format parser. Attackers could exploit the flaw by getting users to open maliciously crafted JPEG images. Talos researchers notified the vendor of the vulnerability in July; it has been fixed in a recent update.


[Editor Comments ]



[Williams ]
The most likely attack vector for most users is through the handling of PDF's since a number of PDF readers use OpenJPEG for handling JPEG data. Patches will likely be released quickly by vendors, but since this is a relatively easy to exploit vulnerability (as heap exploits go) users should apply patches as soon as they are available.

Army is Ahead of Other Services in Establishing Cyber Mission Forces (October 3, 2016)

General Robert Abrams, commanding general of the US Army Forces Command, said the Army is "the only service that's created its own cyber branch and its own military occupational specialty for enlisted
[personnel ]
." The Army has conducted five cyber training exercises over the past year. General Abrams also said that "there's a tremendous amount of tactical application" that cannot yet be implemented because there is not the authority to use them.


[Editor Comments ]



[Assante ]
For the Cyber Protection Teams (CPTs) there is no lack of opportunities to find intrusions. For the remainder of the force, it is essential that training simulations, exercises, and tests provide facsimiles of 'real world' experiences to develop the necessary methods and memory that will sharpen these forces.

DressCode Trojan Found in Apps in Google Play Store (September 30 & October 3, 2016)

A Trojan horse program known as DressCode has been found on more than 400 apps in the Google Play Store. The malware has been detected in 3,000 Android apps overall. DressCode is capable of making its way onto networks that infected devices connect to and stealing data.


[Editor Comments ]



[Murray ]
Of course, the real issue is not so much how many dirty apps there are as how many devices have copies of them. Nice people do not give Android devices to children, the elderly, or the otherwise naive.
