--National Infrastructure Advisory Council Report - A Pre 9-11 Moment (August 22 & 23, 2017)

"There is a narrow and fleeting window of opportunity before a watershed, 9/11-level cyber attack, [for the nation] to organize effectively and take bold action," said the US National Infrastructure Advisory Council report. The report lists 11 recommendations, including "establish separate, secure communications networks specifically designated for the most critical cyber networks; ... identify best-in-class scanning tools and assessment practices; ... [and] establish clear protocols to rapidly declassify cyber threat information."

[Editor Comments]
[Assante] The experience and foresight of the industry leaders comprising the council warrants policy makers and peers to pay close attention. Their statement regarding the pace of cyber threats and corresponding urgency to get our house in order should serve as a final warning. The time for action is now, as we race forward into a more digital and connected world.
[Paller] As Mike Assante notes, the NIAC members accurately describe the problem. Many of the solutions they offer, however, may not be the right ones as John Pescatore notes below.
[Pescatore] Out of the 11 top level recommendations, most are standard committee output (more industry/govt. sharing, more task forces, senior government meetings), and most of the others are standard security goodness (reach basic security hygiene, faster above the line/below the line declassifying of govt threat data, etc.) The "separate, secure communications network" is the most attention getting but makes no sense as proposed as the primary method for Critical Infrastructure communications (the report says have an RF-based backup.) It makes real sense as a backup approach, but pretending that systems that haven't been made secure will magically be secure if they don't seem to have direct Internet connectivity is what got power systems, ATM machines, voting machines etc. in trouble in the first place.

--AccuWeather Updates App to Fix Data Privacy Problem (Maybe) (August 23, 2017)

AccuWeather has updated its app to address an issue that collected location data even when users had not granted the app permission. Prior to the update, AccuWeather shared all users' router names and basic service set identifiers with Reveal Mobile, an AccuWeather tech partner.

[Editor Comments]
[Northcutt] Once you understand the problem reading the AccuWeather blog post is instructive. Three examples:
1) no GPS coordinates are collected or passed without further opt-in permission from the user. = = Right, the SSID of the router is passed and the location of most WiFi routers is known.
2) Accordingly, at no point was the data used by AccuWeather for any purpose. = = Correct, as we best understand, that is why AccuWeather has a business relationship with Reveal Mobile. If that is not correct, what is the reason AccuWeather is hooked up with Reveal Mobile?
3) the end result should be that zero data is transmitted back to Reveal Mobile when someone opts out of location sharing. = = That could be, but when you look Reveal Mobile up on Google, their tag line is "Turn Location Data into Meaningful Mobile Revenue"
Bottom line: To have collected the data after users opted out and then issuing a misleading blog indicates using an alternate weather forecast source such as might be sensible. A note to other companies caught doing inappropriate things: history is starting to show saying you are sorry and promising never to do it again often plays better. Just mean it when you say it.

--FBI Files Charges Against Alleged Malware Distributor (August 24 & 25, 2017)

The FBI has filed charges against a Chinese man for allegedly distributing malware that was used in attacks targeting systems at several US companies. Yu Pingan was arrested in Los Angeles on Monday, August 21. According to the indictment, Yu Pingan distributed malware that may have been used in attacks against systems belonging to the US Office of Personnel Management (OPM) and the Anthem health insurance company.

--Microsoft Settles with German Consumer Rights Group Over OS Downloads (August 24, 2017)

Concluding an 18-month legal wrangle with a German consumer rights organization, Microsoft has agreed to stop forcibly downloading upgrades for Windows operating systems onto computers in Germany. The company admitted wrongdoing in downloading more than 6GB of data onto users' devices in 2015. Microsoft will not download any operating systems updates without the user's express permission, and will pay penalties if it breaks the agreement.

[Editor Comments]
[Murray] Some consumers are unlikely to authorize patching and are more likely to attach vulnerable systems to the Internet. While this agreement may avoid some inconvenience to a small number of consumers, it will weaken the infrastructure.

--Baratov Pleads Not Guilty in Yahoo! Breach Case (August 23 & 24, 2017)

Karim Baratov has pleaded not guilty to 47 charges related to the compromise of hundreds of millions of Yahoo! accounts. Baratov was recently extradited from Canada. Court documents say that Baratov and Alexey Belan were hired by two Russian FSB officers, Dmitry Dokuchaev and Igor Suschin, to break into Yahoo!'s systems in 2014.

--ROPEMAKER Attack Lets Attackers Alter eMail Content After Delivery (August 22 & 23, 2017)

An attack known as Ropemaker, for Remotely Originated Post-delivery Email Manipulation Attacks Keeping Email Risky, lets attackers change the content of email once it has been delivered to a user's inbox. The attack works by remotely altering cascading style sheets (CSS) in HTML emails.

[Editor Comments]
[Neely] This attack is not been seen in the wild. It applies only to desktop email clients; it fails on browser-based email clients as they strip out header tags required by this exploit. Modern email content delivery depends on HTML rendering to deliver a rich user experience, so users are disinclined to turn off support for HTML in email. Beyond disabling HTML email, a network filter could be added blocking remote CSS download by email clients.

--Fuze Fixes Security Problems (August 22 & 23, 2017)

Fuze has fixed three vulnerabilities in its voice messaging and collaboration platform that could be exploited to expose user account information and allow unauthorized access. Rapid7 notified Fuze of the security issues in mid-April. Fuze released fixes for the flaws by May 6, but the issues were only publicly disclosed earlier this week.

--Second Ukraine Accounting Company May Have Been Hacked (August 22 & 23, 2017)

A Ukrainian cyber security firm says it believes it has detected another instance in which computers at an accounting software company were compromised and are being used to spread malware. The scenario bears many similarities to the Petya/NotPetya malware infections that spread earlier this summer.

--Google Removes Hundreds of Android Apps from Google Play Store Over Spyware Concerns (August 21 & 23, 2017)

Google has pulled more than 500 Android apps from the Google Play Store after finding that they were infected with an adware software development kit (SDK) that could download malicious plug-ins. Apps containing the Igexin SDK have been downloaded more than 100 million times.

[Editor Comments]
[Neely] The affected applications included an advertising SDK that could download malicious plug-ins. Symantec issued warnings about the lgexin SDK back in 2015, but it wasn't until the SDK moved from potentially taking action to actively doing so that Google remove the applications. The best mitigation is to use devices with current Android releases so you have Google's most current protections from malicious behavior.

--Google's Titan Security Chip (August 22, 2017)

Google plans to disclose information about its Titan security chip this week. Titan was developed to help improve security for Google's cloud computing network. The chip has already been installed in the servers and network cards in Google's data centers. The Titan chip checks to see if hardware has been altered; if it detects an anomaly, it will shut down the hardware to prevent it from booting.

[Editor Comments]
[Pescatore] What Google has done is essentially design a custom Trusted Platform Module (TPM) chip for Google's hardware. Let's call it TPM+ because it actually does a few things better than the Trusted Computing Group standard TPM, which has been around for over 10 years and gets hardly any use at all. The TCG TPM suffered from a "try to make every vendor in TCG happy" approach. Google's Titan "TPM+" is a "let's solve a real security problem for our own customers" approach. In reality, most major steps forward in security happen this way - notice that in the mobile phone world, you didn't see Apple or Google using industry standard approaches to roll out App Stores, sandboxing, etc.
