--Google Selling 2FA Security Keys

(August 30, 2018)

Google is now selling its USB and Bluetooth Titan FIDO-based security keys for two factor authentication (2FA). Google has been using the keys internally; last month, the company said that since the keys use has been adopted more than eight months ago, none of its employees accounts has been phished.  


[Editor Comments]


[Pescatore] Good news/bad news: there is a waiting list to buy Googles Titan security key. Thats good news if it signifies high demand, bad news if it is because Google did the announcement before it had the production capacity. The single biggest thing that Google/Apple/Facebook/Twitter/Microsoft/Paypal etc. can do to advance cybersecurity is to actively drive up the use of strong authentication.


[Neely] Making it easier for users to implement 2FA is key to adoption. These keys provide the verification through USB, bluetooth or NFC connections with a complex handshake, not just a one-time code; that makes spoofing impractical. The biggest challenge will be making sure that all your use cases support the devices, e.g. Android doesnt currently support NFC Titan keys, and that you remember to disable fallback to a reusable credential.


[Murray] Even after a month of restricted sales, they sold out in half a day; latecomers were put on a waiting list. This product (actually two keys?) can reduce the inconvenience of strong authentication but at a price that many consumers may be unlikely to pay. While this product does provide some (unique) protection against fraudulent provisioning attacks, there will still be social engineering attacks targeting support desks. One can take some comfort in knowing that ten percent of Google users have opted into the Google strong authentication system. This contradicts the assertion of some still resisting enterprise security people that users will not tolerate strong authentication solutions.  

 

[Northcutt] I am a big believer in 2FA authentication. As soon as I read the news about the announcement I zoomed up to the Google store to buy one. I was put on a waiting list. After I get it I will try to post a first look at the bottom of NewsBites.

--GAO Report: Census Bureau Cybersecurity

(August 30, 2018)

A report from the US Government Accountability Office (GAO) found more than 3,000 security issues in Census Bureau IT systems that need to be addressed before 2020. Of the identified flaws, 43 are rated high risk or very high risk. The actual number of flaws could actually be higher as there are some Census systems that have not yet been examined.


[Editor Comments]


[Neely] The Census Bureau is performing a huge IT modernization task prior to conducting the 2020 census. This report captures the status during the 2018 testing exercises which is midway along their project plan. The GAO previously identified 93 recommendations for the 2020 census, 61 of which have been implemented, and plans have been implemented to address the remaining 32. The issue here is, as usual, one of getting needed resources to implement these plans and achieve approval to operate prior to starting the census.


[Pescatore] The Census count is obviously the holy grail for attackers that want to disrupt the US democratic system. Back in 1995 or so, I testified to Congress when the Social Security Administration first wanted to put what is now called your personal Social Security Statement online. That was delayed a few years and SSA did a good job making sure it was done securely. The Census Bureau actually seems to be making progress on the cybersecurity side, but the staffing and management problems detailed in the report need emergency attention.

-DoJ: CFAA May Not Currently Apply to Hacking Voting Machines

(August 30, 2018)

A July 2018 report from the US Department of Justice (DoJ) suggests that the Computer Fraud and Abuse Act (CFAA), a law frequently used to prosecute cybercrimes, may not apply to those who interfere with electronic voting systems. According to the report, the CFAA prohibits hacking into machines that are connected to the Internet. Experts are skeptical of the claims, maintaining that the CFAA has not been interpreted this way in past cases. A bill introduced in the Senate in July 2018 would amend the CFAA to ensure it covers voting machines.


[Editor Comments]


[Murray] Fraud and abuse are still crimes. The CFAA was intended to make them easier to prosecute. To the extent that this is a problem, it is easily remedied.

--Firefox Will Roll Out Anti-Tracking Features

(August 30, 2018)

Mozilla says that future versions of Firefox will help protect users privacy, block malicious scripts, and shorten webpage loading times by blocking cross-site tracking scripts, slow tracking scripts, and malicious miner and fingerprinting scripts. The new features will be rolled out over several versions of Firefox during the next few months.


[Editor Comments]


[Murray] New features of browsers to remedy old features of browsers. Enterprise users should prefer isolated or locked-down systems for browsing the web and doing e-mail.  


[Neely] As web drive-by methods remain in the top five mechanisms by which endpoints get compromised, blocking these scripts will help give users an added level of defense. The features are available in the Firefox 63 nightly build, with parity expected in Firefox ESR 60.3. Expect releases this fall.

--Cobalt Cybercrime Group Targeting Bank Employees

(August 30, 2018)

The cybercrime group known as Cobalt is believed to be responsible for attacks against ATMs and the SWIFT international financial messaging systems. The group appears to be launching a new set of phishing attacks against employees at two financial institutions: NS Bank in Russia and Patria Bank in Romania.


[Editor Comments]


[Murray] It is urgent that even small banks adopt strong authentication and true end-to-end encryption measures to resist lateral compromise after one employee clicks on a bait object.

--Misfortune Cookie Flaw Affects Medical Devices

(August 30, 2018)

The US Department of Homeland Securitys (DHSs) Industrial Control Systems Computer Emergency Response Team (ICS-CERT) has issued an advisory warning of a vulnerability in Qualcomm Life Capsule Datacaptor Terminal Server that could be exploited to allow an attacker to execute unauthorized code to obtain administrator-level privileges on the device. The flaw, known as Misfortune Cookie, was first detected four years ago; at that time, it affected servers. This time, it has been found to affect medical devices. Qualcomm Life has developed a fix to address the vulnerability.

--Chinese Hotel Chain Data Theft

(August 29, 2018)

Chinas Huazhu hotel chain has acknowledged that customer data may have been stolen and offered for sale on the Internet. Nearly 500 million pieces of data appear to be advertised on a darknet site. The number of affected customers is estimated to be 1130m million.


[Editor Comments]


[Neely] The root cause appears to be a developer uploading the internal database to GitHub. Create a process to monitor your GitHub and other external code repositories for deliberate or accidental inclusion of inappropriate information such as databases and SSH private keys, and assure proper access controls are in place to protect company IP.

--Fiserv Fixes Flaw That Exposed Customer Account Transaction Information

(August 28, 2018)

Fiserv has fixed a security issue in its web platform that is used by numerous financial institutions. The flaw involves alerts for account transactions. The alert event numbers are assigned sequentially, so if a customer has chosen to receive the alerts, they can view transaction information for other peoples accounts simply by changing the number in the browser. Fiserv has developed a fix for the issue and pushed it out to clients that use hosted versions of the affected products. The company said it planned to deploy the fix to clients using in-house versions of affected products earlier this week.
