--PA Supreme Court: Employer Has an Obligation to Secure Employee Data

(November 27, 2018)

A decision from Pennsylvanias Supreme Court says that the University of Pittsburgh Medical Center (UPMC) has a common law duty to protect its employees personal data that are stored on a computer that can be accessed from the Internet. The plaintiffs alleged that they provided the data, which included Social Security numbers, tax information, and bank account information, to UPMC as a condition of their employment.

--House IoT Bill Would Encourage Agencies to Focus on Security Over Price

(December 6, 2018)

A bill to be introduced in the US House of Representatives next week would require that Internet-connected devices purchased by the government meet certain security standards. The basic security requirements include functionality to accept security updates/patches, and allowing users to change the default passwords. Vendors would also be required to notify agencies when vulnerabilities are detected and must release timely updates to address the flaws. The bill also explicitly directs the OMB director and GSA administrator to guide agencies in limiting the use of lowest price technically acceptable criteria for purchases. The bill is a companion bill to the Senates Internet of Things Cybersecurity Improvement Act.


[Editor Comments]


[Pescatore] This is a baby step forward for Federal procurement focusing on driving security levels higher, but it takes a step in a very important direction.


[Neely] Even so, internet-connected IoT should have constrained network access to protect them and other network devices. It is important to note that the bill also includes provisions for non-compliant devices, including micro-segmentation, intelligent gateways, isolation and other external factors needed to provide comprehensive protection.

 

[Murray] While it seems to many to be necessary, not all appliances should include the functionality to accept security updates/patches. This functionality dramatically increases the attack surface of the device. It is this functionality that is used to incorporate the device into botnets. Many cheaper devices should simply be discarded if they prove to be insecure. Similarly, we should be discouraging the use of passwords for any such functionality that we do include. We should encourage a system using asymmetric key encryption such as Apple uses.

--Tools Used in Marriott Breach Were Used in Other Attacks

(December 5, 2018)

Investigators looking into the Marriott Starwood breach say that some of the tools and techniques used in the attack were used in other attacks that have been attributed to Chinese hackers. The tools have been posted online, which means that other groups could have obtained them as well. Investigators also say that it is possible that multiple hacking groups had a presence in the system. The breach began in 2014, shortly after the massive breach of systems at the US Office of Personnel Management (OPM). The four-year dwell time prior to the breachs detection suggests that those responsible are working on behalf of a nation-state, according to Gartner analyst and VP Avivah Litan.   


[Editor Comments]


[Ullrich] A four year dwell time does not necessarily suggest a nation state actor. Missed detection is due either to a sophisticated attacker, or to not-sufficiently-sophisticated security monitoring. The attribution to Chinese hackers appears to be weak so far, in particular connecting them to nation state interests. This just appears to follow the classic post-breach PR playbook of playing up the skills of the attacker to appear less negligent in allowing the breach to persist for four years. The same article also mentions that several hacking groups likely had access to the data. I doubt they were all highly sophisticated nation state actors.

--Australian Parliamentary Committee Report Recommends Against eVoting

(December 6, 2018)

An Australian parliamentary committee has concluded that current technology is not sufficiently mature for an election to be conducted through a full scale electronic voting process, and recommends sticking with paper ballots. The Joint Standing Committee on Electoral Matters report on Australias 2016 federal election voiced concerns about the cost, security and verification of results associated with electronic voting.


[Editor Comments]


[Pescatore] Electronic voting is kind of like digital watches, or keypad entry on house doors vs. physical keys: yes, the technology can do it and it sounds kind of neat. But reliability goes down, costs goes up and security can go down. It doesnt have to go down, but it does if the focus is simply on new technology vs. better technology.

--Australian Encryption Bill Passes

(December 6 & 7, 2018)

After much contentious parliamentary debate, Australias controversial encryption bill has passed. Critics of the legislation say it will weaken encryption by capitulating to the demands of law enforcement and the government. The law requires that technology companies provide a means of accessing encrypted communications and information if served with a warrant.

--Huawei CFO Arrested in Canada at US Governments Request

(December 5 & 6, 2018)

Canadian authorities have detained Huawei chief finance officer (CFO) Wanzhou Meng at the request of the US government, which is seeking extradition. Specifics have not been released as a Canadian court has approved Wanzhous request for a ban on publishing details. However, it is known that DOJ has been investigating possible violations of sanctions against Iran by Huawei. Wanzhous arrest in Vancouver, BC, on December 1, coincides with Australias, New Zealands, and the USs decisions to ban the use of Huawei products in 5G network infrastructure. The UK has not blocked the use of Huawei products, but UK telecom BT Group has said it will remove Huawei products from its 3G and 4G core networks within the next two years, and will not include Huawei in the vendor selection for its 5G core network.

--Adobe Releases Fix for Zero-Day Flash Flaw

(December 5, 2018)

Adobe has released a patch for a vulnerability in its Flash Player outside of its regularly scheduled security updates. The use after free flaw could be exploited to allow arbitrary code execution. The flaw is being actively exploited in a phishing campaign with the help of a maliciously-crafted Word document.


[Editor Comments]


[Ullrich] A proof-of-concept exploit has been made public for this vulnerability. Sadly, some browsers (e.g. Chrome and Edge) include Flash as a built-in component. Dont forget to update affected browsers. For everybody else: remove Flash.


[Neely] Given that significant vulnerabilities in Flash continue to be discovered, and Adobe is unlikely to release fixes after it goes EOL in 2020, it is critical to make sure your project to eliminate its use is on-track to complete well before 12/31/2020.


[Northcutt] The major browsers dropped Flash in 2016. When I was taking the Washington State food worker safety course, I had to use a virtual browser, (Silo by Authentic8), to view the material.

--Citrix Clarifies Reason for Forced Password Resets

(December 4, 2018)

In a December 4 blog post, Citrix explains that it made the decision to force users to reset their ShareFile passwords because it detected a credential stuffing attack against ShareFile users. Credential stuffing involves trying username and passwords combinations stolen from one site on other sites in the hope that some users reuse their access credentials on multiple accounts. Citrix pointed out that there have been a record number of breaches compromising this type of information in 2018, and that the suspicious activity it detected occurred shortly after several high-profile breaches were disclosed. In response to questions from Brian Krebs, Citrix wrote that they did not enforce a password reset on accounts that are using more stringent authentication controls.

 --December Android Updates

(December 4, 2018)

In its December update for Android, Google has fixed 53 different vulnerabilities, including 11 that are rated critical. Of those, six could be exploited to remotely execute code in the Android Media Framework and System components. Google handsets will receive over-the-air updates. Update delivery for other devices will vary by manufacturer and carrier.


[Editor Comments]


[Neely] While these fixes address flaws in Android 7.0 through 9, check your hardware providers lifecycle support information to determine if and when you will see the update for your particular device. Measure the time from when your device was released, not purchased. Android 7 was released in August 2016. For manufacturers that provide updates, by year three only security fixes are distributed and sometimes less frequently.

--Quora Breach Affects 100 Million Users

(December 3 & 4, 2018)

Question and answer site Quora has disclosed a breach it detected on Friday, November 30. In a blog post that outlines what is currently known about the breach, Quora chief executive Adam DAngelo wrote that the incident is being investigated and that the company want[s] to be as transparent as possible without compromising our security systems or the steps we're taking. Quora has logged affected users out of the service and has invalidated their passwords.

 

[Editor Comments]

 

[Murray] It remains to be seen what Quoras contribution to the breach was. However, they got the disclosure right, both timing and transparency.
