Facebook Forces Mass Logout After Breach

(September 28 & October 1, 2018)

Facebook logged 90 million users out of their accounts after the company discovered that hackers had been exploiting a flaw in Facebook code that allowed them to steal Facebook access tokens and take over other peoples accounts. The stolen tokens could also be used to access apps and websites linked to the Facebook accounts. The hackers exploited a trio of flaws that affected the View As feature, which lets users see how their profiles appear to other people. Facebook has fixed the security issue; it has also reset the access tokens for 90 million accounts. Facebook became aware of the issue on September 16, when it noticed an unusual spike in people accessing Facebook.


[Editor Comments]


[Neely] The forced logout invalidated the existing authentication session tokens, meaning they could not be used to login to Facebook or any other sites enabled to allow access via your Facebook credentials. While Facebook has worked to identify all impacted users, consider logging out all of your Facebook sessions to be sure your authentication tokens are not at risk. This is done from the security settings where you can see and logout all your active sessions.


[Pescatore] Since it is National Computer Security Awareness Month and a lot of awareness presentations are being given, it is good advice to tell employees never use those Login with Facebook buttons on websites in their personal online activities.

Breached Singapore Health Server Was Unpatched for More Than a Year

(September 27, 2018)

A compromised server that led to a massive breach of Singapores SingHealth healthcare group member data had not been patched for 14 months prior to the breach. The person who was managing the server was doing so unofficially. He was not trained in cyber security or server administration and did not have procedures for handling security incidents.

Karen Evans Answers House Energy and Commerce Committees Questions About CESER

(September 27 & 28, 2018)

Karen Evans, assistant secretary of the DoE's Office of Cybersecurity, Energy Security, and Emergency Response (CESER), answered questions about her office, which was established earlier this year. Evans was sworn in in early September. In her written testimony, Evans noted that the Department is focusing cyber support efforts to strengthen energy sector cybersecurity preparedness, coordinate cyber incident response and recovery, and accelerate game-changing research, development, and deployment (RD&D) of resilient energy delivery systems. Evans also told legislators that she plans to distill threat intelligence into actionable reports for operators of critical infrastructure without disclosing classified information, so the operators do not need to go through the laborious process of obtaining security clearances to receive the information. In the video below, Evans addresses this issue in response to a question posed by Rep. Jerry McNerney (D-CA); McNerneys question begins at 57:30; Evans response at 58:30.


[Editor Comments]


[Paller] Many people are unaware of Asst. Sec. Evans background and may underestimate how quickly and effectively she will make the new CESAR into a high-impact agency in the single most important area of critical infrastructureelectric power.  The question some observers are asking is not whether she will have a major impact, but whether the U.S. government waited too long to put someone in place who can make a difference before a major attack turns the power off across large areas.

Tesco Bank Fined 2.26m Over November 2016 Breach

(October 1, 2018)

The UKs Financial Conduct Authority (FCA)has fined Tesco Bank 16.4m ($21.4m USD) for a data breach that led to the theft of 2.26m ($3.4m USD) from its customers. In all, 40,000 Tesco accounts were compromised and funds stolen from 9,000 of those. Following the breach, Tesco temporarily froze online transactions for all account holders, which created further problems for customers. The FCA called the November 2016 incident largely avoidable. A year before the attack, Tesco had received a fraud alert from Visa about the type of attack that eventually hit its systems.

Chrome Seeks to Make Extensions More Trustworthy

(October 1, 2018)

Google has announced that it will implement measures to keep malicious extensions out of the GooglePlay store. Google will look more closely at extensions that ask for expansive permissions and will reject extensions that contain obfuscated code. In Chrome 70, users will be able to restrict the activity of extensions that try to modify web pages. Next year, Google extension developers will be required to complete revised manifests that describe the privileges their extensions require and to use two-factor authentication to make it more difficult for hackers to access their accounts. In a separate story, Chrome extension developers were targeted in a phishing campaign that tries to get the developers to disclose their account credentials.


[Editor Comments]


[Pescatore] Extensions have been to browsers as DLLs have been to Windows. Both encourage independent software vendors to add functionality to the base platform, but the security ramifications were not thought through before the additions were built. Thus, lots of backfilling and spackling is constantly required. Google taking steps to make sure extensions must come from the Google Play app store (read: a big whitelist) is a good thing, and should be the norm for all browsers. Doing a better job of making sure fewer malicious apps and extensions ever get into the app store is the prerequisite.


[Murray] One is reminded of the Security claims that were made for Chrome when it was announced. It should not surprise anyone that those claims were not realized. Browsers are both fundamentally vulnerable and difficult to implement safely. Enterprise users should continue to prefer browsing only from isolated or locked-down devices. As Harry DeMaio cautions, Doing business on the World Wide Web is like doing business in Times Square. (All strong authentication is multi-factor but not all multi-factor is strong. Competent security people do not say two-factor when they mean strong.)

US Government Sues California Over Net Neutrality Law

(September 30, 2018)

On Sunday, September 30, California Governor Jerry Brown signed into law net neutrality legislation, which was introduced after the Federal Communications Commission (FCC) decided to repeal net neutrality rules. Later that same day, the US Department of Justice (DOJ) sued the state of California, alleging that the law is illegal because states do not have the authority to regulate interstate commerce.

DOD Needs More Latitude in Hiring Cyber Personnel

(September 28, 2018)

At a September 26 Senate hearing, US Department of Defense (DOD) principal deputy CIO Essye Miller told members of the Senate Armed Services Committee's Personnel and Cybersecurity subcommittees that 4,000 civilian cyber-related employees have left the agency in the past year. The majority of the workers were in IT management and computer science. DOD needs employees with a wide variety of cyber skills. Brig. Gen. Dennis Crall, the principal deputy cyber advisor and senior military advisor for cyber policy for the defense secretary's office, who also testified before the committee, says DOD wants to increase pay and streamline the hiring process.

FBIs IC3 Warns of Increased RDP Exploits

(September 27, 28 & October 1, 2018)

The FBIs Internet Crime Complaint Center (IC3) and the Department of Homeland Security (DHS) have issued a joint warning that Windows Remote Desktop Protocol (RDP) is increasingly being used as an attack vector. RDP has been used to spread ransomware and other types of malware. The FBI and DHS recommend that organizations use strong passwords, employ two-factor authentication, ensure that the versions of RDP they use are up to date, restrict access to the default RDP port, and disable the service if it is not needed. Organizations are also advised to enable logs and make sure the logs include RDP logins.


[Editor Comments]


[Murray] Strong passwords address brute force attacks; this is not what we are seeing. What is indicated is strong authentication (at least two kinds of evidence, at least one of which is resistant to replay.)

ATM Jackpotter Sentenced

(September 26 & 28, 2018)

Argenys Rodriguez has been sentenced to one year and one day in prison for his role in an ATM jackpotting scheme. Jackpotting involves manipulating ATMs to dispense all their cash. Rodriguez is the first person in the US to be sentenced for jackpotting. He and an accomplice managed to install Ploutus malware on ATMs in Connecticut and Rhode Island. They were arrested in January 2018, shortly after ATM company Diebold Nixdorf issued a warning that jackpotting activity had been detected in the US. Rodriguez pleaded guilty in June to conspiracy to commit bank fraud.

International Cyber Attack Metrics Dont Add Up

(September 27, 2018)

How do countries count cyberattacks? One says that there were 24,000 attacks against defense targets in one year; another claims 110 attempts to break into government servers during that same year; and a third notes an average of 500 cyberattacks a month against defense infrastructure. Governments in several countries have acknowledged that they do not have one single set of standards and reporting metrics. What one country deems critical may not be considered critical in another. For international entities such as EU and NATO, this inconsistency is problematic. The article observes that without published standards and discernable metrics, such warnings are of no real value to the public.


[Editor Comments]


[Pescatore] Number of attacks is never a meaningful, let alone useful, metric, any more than number of raindrops hitting a roof would be a meaningful metric. Retail tracks revenue damage due to shrinkage (shoplifting and employee theft) not the number of times someone tries to steal a shirt at the clothing store. That is why reports looking at actual damage like the Verizon Data Breach Investigation Report and Microsofts Security Intelligence report [well, parts of it], are much more useful than the numerous billions and billions of attacks are being observed reports.

Bill Would Codify Federal CIO Role Changes

(September 26, 2018)

The Federal CIO Authorization Act of 2018, introduced in the US House of Representatives last week, would elevate the position of federal CIO to a presidential appointment reporting to the director of the Office of Management and Budget (OMB). The federal CIO currently reports to the OMB deputy director for management. The bill would also rename the Office of E-Government to the Office of the Federal Chief Information Officer. Rep. Will Hurd (R-TX), one of the bills co-sponsors along with Re. Robin Kelly (D-IL), said that it makes a clear statement that the federal CIO is in charge of coordinating IT policy across the government.
