ThreatExchange Lets Companies Share Cyberthreat Information (February 11 & 12, 2015)

Cyberthreat specialists from several social media, including Facebook, Tumblr, and Pinterest, gathered to figure out a way to stop a botnet from spreading malware across the Internet. The Facebook team realized that they couldn't call meetings every time a security issue arose, so they developed ThreatExchange, a way for the companies' systems to communicate with one another in real time to share information.




[Editor's Note (Murray): Imagine! They did this without "immunity" from Congress.
(Ullrich) Great initiative. We need to automate these systems more. There are too many mailing lists and threat groups already and the response needs to happen faster. I hope that this effort will be able to leverage standards like STIX/TAXI to allow it to scale and integrate beyond this particular use case.
(Honan): It is great to see initiatives such as this take place and threat information being shared openly amongst companies. Of course the real test will be the quality of the information provided and the value it can bring to an organisation that subscribes to one, or many, of these platforms. The European Network and Information Security Agency (ENISA) published a very useful paper related to this topic "Standards and tools for exchange and processing of actionable information".

Dutch Government Websites Affected by DDoS Attack (February 12, 2015)

Government websites in the Netherlands were inaccessible for several hours earlier this week due to a distributed denial-of-service (DDoS) attack. Some private websites were also affected by the attack. The attack was launched against hosting provider Prolocation.
[Editor's Note (Honan): In today's threat environment there really is no excuse for companies not having a DDoS prevention service to protect their website(s). ]

Microsoft Patches 55 Flaws (February 10 & 11, 2015)

On Tuesday, February 11, Microsoft released nine security bulletins to address 55 flaws in Windows, Internet Explorer (IE), and other products. Microsoft announced last month that it would no longer be providing advance notification of the bulletins to the general public. Forty-one of the vulnerabilities patched are in IE. Among the other flaws fixed is a remote code execution flaw in Active Directory that took Microsoft a year to develop, and the issue is not patchable in Windows Server 2003.



[Editor's Note (Murray): Surely that is the last one; now we can all relax. That said, fixes to security infrastructure, e.g., Active Directory, should take priority.
(Ullrich): Sadly, Microsofts patch quality is not improving. Again, one patch failed to apply correctly if the user was not logged in as Administrator. Also note that the very important GPO patch is not fully affective until the respective configuration has been changed to enable the requirement for mutual authentication and integrity verification. ]

EU Parliament Blocks Mobile Outlook App (February 12, 2015)

The European Union (EU) Parliament has decided that politicians may not use the Microsoft mobile Outlook app due to security and privacy issues. The Parliament's IT department has told staff members to delete the app. The concern is that Outlook holds data and user credentials on servers in the cloud, beyond the Parliament's control. The University of Wisconsin has banned the app's use as well.

[Editor's Note (Pescatore): Microsoft acquired this app from Acompli and seems to have rushed it to market. Because it stores login credentials externally Acompli bypasses ActiveSync and any ActiveSync security policies you have implemented. That alone is enough to block usage, but if something of that magnitude was overlooked there are likely other issues. Microsoft has said it is working on fixing the known vulnerabilities. ]

Facebook Fixes Flaw That Could Have Been Exploited to Delete Pictures (February 12, 2015)

Facebook responded quickly after being notified of a flaw in the site's Graph API that could have been exploited to delete other people's photos. The vulnerability was patched within two hours of the notification.



Apple Adds Two-factor Authentication to FaceTime and iMessage (February 12, 2015)

Apple is expanding its use of two-factor authentication to FaceTime and iMessage. Apple began offering two-factor authentication for iCloud last fall. iCloud users who have already enabled the two-factor option will automatically find themselves prompted for app-specific passwords which are generated on the AppleID management page.

[Editor's Note (Pescatore): iTunes and the Apple App Store still aren't under the two factor authentication umbrella. Adding those would help increase the adoption - anything that gets home users moving off of reusable passwords helps them accept the same thing at work.
(Murray): I agree with John P. that whatever promotes the use of strong authentication is a good thing. However, I find the idea that "work" is waiting for "home" unprofessional and offensive. ]

FBI Investigating Fraudulent TurboTax State Returns (February 11 & 12, 2015)

The FBI is investigating reports that fraudulent state tax returns were submitted through Intuit's TurboTax software. Intuit briefly suspended filing state returns through TurboTax while it determined that its systems had not been breached and concluded that the information used to file the fraudulent claims was obtained elsewhere. The FBI is investigating to verify the validity of Intuit's assertion that the breach occurred elsewhere and to determine whether the issue affects federal returns as well.


[Editor's Note (Murray): One would like to think that the role of the FBI would be to identify and arrest the perpetrators, rather than simply determine the method.
(Ullrich): Fraudulent Tax returns are a relatively easy way to "cash out" stolen social security numbers. But this type of fraud not only costs taxpayer's money, it also causes considerable pain to the impersonated victim as they may now not be able to file a return and receive a refund until jumping through additional hoops. Software like Turbo Tax just enables this fraud and makes it simpler to execute. ]

Smartphone Thefts Down After Kill Switch Implemented (February 11, 2015)

Authorities in three major cities say that kill switches on smartphones have noticeably reduced thefts of the devices. Apple added the feature in 2013, and since that time, iPhone thefts have dropped by 25 percent in New York, by 40 percent in San Francisco, and by 50 percent in London. Overall cellphone thefts in that period fell by 16 percent in New York, and 27 percent in San Francisco. The decline in thefts in London overall was 50 percent.


NIST Seeking Comment on ICS Security Guide (February 11, 2015)

The National Institute of Standards and Technology (NIST) is seeking public comment on the final draft version of its Industrial Control Systems (ICS) security guide. This is final public review. Comments accepted through March 10, 2015.

[Editor's Note (Murray): My comment is the same as I have been giving, and they have been ignoring, for the last thirty years: write in the active voice. Bureaucrats are unable to do that because then someone might be held accountable.
(Assante): The addition of placing a sharp focus on safety for the framework for risk management decisions is important. The authors then use an example that sets security practices against safety concerns, but this is only one element of framing risk. The loss of integrity to unauthorized parties represents a very real safety concern, especially as some industrial environments are moving to integrated safety and control systems. Many would argue that sacrificing the availability of the control system to a safe shutdown is preferable if the control system was compromised resulting in unpredictable operating conditions. ]

Attackers Used Forbes Site in Watering Hole Attack (February 10 & 11, 2015)

Cyber attackers operating through China were reportedly able to launch attacks against US defense and financial companies last year by compromising the Forbes news site. The attackers exploited unpatched vulnerabilities in Adobe Flash and Microsoft Internet Explorer (IE) late last year. Specifically, the attackers infected a Flash widget on the Forbes site and used it to serve malicious code to specific site visitors. The allegations were made in a report from iSIGHT Partners and Invincea.




[Editor's Note (Murray): It is hard to blame Forbes for this; everyone used Flash then. On the other hand, users ought to be able to safely visit a Forbes site. It should now be obvious to the operators of similar sites that they should prefer html 5 to Flash. ]

Federal Contract Administrator Investigating Possible Breach (February 10, 2015)

The US Defense Contract Management Agency (DCMA) has taken several servers offline while it investigates a possible security breach. DCMA administers contracts for the US Department of Defense (DoD). A spokesperson said that the agency noticed suspicious activity on one of its public facing servers in late January.

[Editor's Note (Murray): Do I understand correctly that they discovered this on their own, without relying upon a warning from Krebs like everyone else? ]
