“Also worth reading are this EFF essay, and this ACLU white paper.

Susan Landau on contact tracing apps and how they’re being oversold. And Farzad Mostashari, former coordinator for health IT at the Department of Health and Human Services, on contact tracing apps.”

Bruce Schneier’s opinion:

To me, the real problems aren’t around privacy and security. The efficacy of any app-based contact tracing is still unproven. A “contact” from the point of view of an app isn’t the same as an epidemiological contact. And the ratio of infections to contacts is high. We would have to deal with the false positives (being close to someone else, but separated by a partition or other barrier) and the false negatives (not being close to someone else, but contracting the disease through a mutually touched object). And without cheap, fast, and accurate testing, the information from any of these apps isn’t very useful. So I agree with Ross that this is primarily an exercise in that false syllogism: Something must be done. This is something. Therefore, we must do it. It’s techies proposing tech solutions to what is primarily a social problem.

As long as 1) every contact does not result in an infection, and 2) a large percentage of people with the disease are asymptomatic and don’t realize they have it, I can’t see how this sort of app is valuable. If we had cheap, fast, and accurate testing for everyone on demand…maybe. But I still don’t think so.


“Immunity Passports”

Several countries have begun floating the idea of an “immunity passport,” which would certify that someone is immune to COVID-19. Not only does the idea raise a number of security and privacy issues, but there are still unknowns about immunity to this particular virus.
I carry an immunization record with me when traveling internationally, typically a paper form, as well as a digital backup, to be surrendered for examination by border control based on the risk of your origin point, or verification that you meet local mandatory immunization requirements. While COVID-19 changes those factors, the bigger issue is having an internationally recognized indicator of immunity to COVID-19

Protecting Your Web Applications

Solutions and Strategies to Combat Cybersecurity Threats

The rise of cloud computing, use of open source technologies, new data-processing requirements, complexity of web applications, and an increase in the overall sophistication of attackers have combined to create an extremely challenging environment for IT security leadership. Given how critical websites, applications, and online services have become to supporting revenue and productivity, there is nothing more important for your business than ensuring that your digital assets are available and protected at all times. Consider the impact of cyberthreats on your business: customer loss, brand reputation damage or permanent loss of revenue, and team culture demise. In this report, we examine the increasing cyberthreat landscape and take a detailed look at the major threat patterns businesses and security professionals currently experience. We explain how attackers have become so successful and offer remedies to prevent attacks and fix existing vulnerabilities. And, finally, we look at current and emerging trends in efforts to move to cloud-based security, out‐ sourced services, and third-party hosting options

Incidents & events detail

Zoom Brings in Help to Address Security Issues

Zoom is calling in experts to help it address security and privacy concerns. With millions of people working at home during the COVID-19 epidemic, Zoom’s popularity has ballooned. It has also been subjected to greater scrutiny by both hackers and security experts, who have unearthed a number of security and privacy issues. The company has hired numerous security consultants, many of whom are former privacy and security experts from other high-profile tech companies. (Please note that the WSJ story is behind a paywall.)

Zoom’s CEO publicly apologized for “falling short” on security and privacy and Zoom has taken a lot of important steps to improve. But, they aren’t the only video conferencing approach in use and we know attackers are going after them all. SANS is doing a series of webinars on the key elements to making sure all remote work is done as securely as possible that you can access at
There is a lot of FUD around Zoom, and rather than drop it like a hot potato, consideration needs to be given to implementing it securely and applying fixes as they come out. Before jumping to another solution, careful analysis of the security, user experience, and transition costs need to be performed

CVE-2020-1027 | Windows Kernel Elevation of Privilege Vulnerability


Google Removes Malicious Chrome Extensions From Web Store

Google has pulled nearly 50 malicious extensions from the Chrome Web Store. These bad apps were pretending to be legitimate cryptocurrency wallet apps, but actually stole cryptowallet keys and other sensitive information.
A key element of the world recovering from the COVID-19 virus is testing, and a critical part of making widespread testing work will be cellphone apps used for demonstrating an individual’s testing status and tracing possible contacts if someone is found to be infected. Google and Apple need to really step up the security of apps and extensions that make it through their testing. Longer times for most apps and extensions to come out of the process are worth it now to significantly elevate the trust/safety level of phones for this coming critical use. Google and Apple are already working together on the tracing side of the problem. A joint effort on radically reducing “badware” that gets through their testing regimes should be a key part of that

Research of the week

Featuring – Data Exfiltration over DNS Queries via Morse Code

Surprising, this technique is very old (over 20 years), but it is still very effective nowadays.

Probably, you’ll ask why don’t we just upload the compromised files to a cloud storage or directly transfer them via protocols like HTTP, FTP, SSH, Telnet and so on. In order to do exfiltration over the protocols mentioned above, the target machine must initiate a network connection and that will be easily noticed by any basic firewall or monitoring tool.

DNS Exfiltration does not require an active network connection in order to send data over Internet, so basically, it will bypass (almost!) all basic security tools, unless you have an advanced solution in place that analyses outbound DNS queries


New Stealth Magecart Attack Bypasses Payment Services Using Iframes

PCI compliant payment services hosted within an iframe are not immune from Magecart attacks. Website owners are still responsible for any stolen personally identifiable information (PII) or resulting fines. The PerimeterX research team has uncovered a novel technique for bypassing hosted fields iframe protection, which enables Magecart attackers to skim credit card data while allowing successful payment transactions. This stealthy attack technique gives no indication of compromise to the user or the website admin, enabling the skimming to persist on checkout pages for a long time. The users don’t suspect any malicious activity since the transaction succeeds as expected. In this blog post we examine an active use of this technique that targets websites using the popular payment provider Braintree, a subsidiary of PayPal.

Our research team has been actively tracking Inter, a popular digital skimming toolkit used to launch Magecart attacks. Inter is widely known for being sold as a complete digital skimming kit and its ability to easily adapt to many checkout pages on e-commerce sites

An infostealer is a type of malware that is focused on gathering sensitive and conditional information from the compromised system. While this information is often related to the user’s credentials, they have also been known to seek out financial data and personal information. The research performed by CyberArk Labs focused on the methods and techniques that a typical infostealer leverages for stealing sensitive user data and information. Additionally, we wanted to better understand what clients (a.k.a. cybercriminals) are able to retrieve with a low price infostealer such as Raccoon


Remember: Setting the Record Straight: containers vs. Zones vs. Jails vs. VMs

I personally love Zones, Jails, and VMs and I think they all have a particular use case. The confusion with containers primarily lies in assuming they fulfill the same use case as the others; which they do not. Containers allow for a flexibility and control that is not possible with Jails, Zones, or VMs. And THAT IS A FEATURE

##The Challenge of Software Liability

Liability for insecure software is already a reality. The question is whether Congress will step in to give it shape and a coherent legal structure. Broadly speaking, Congress could do this in one of two ways. It could create a legal framework for claims brought by private citizens or state attorneys general. Or it could delegate the regulation of software security to an agency like the Federal Trade Commission (FTC)
