It is often quite difficult when it comes to selecting the proper tech stack for web app development. You will come across lots of technologies, programming languages, and frameworks out there at present which makes the process of selecting the tech stack for businesspersons extremely tough. The primary aspect to take into consideration while developing a web app will be to maintain efficiency for the app. In case more time is consumed for developing an app, you might be required to invest a considerable amount of cash. Node.js happens to be amongst the most inexpensive platforms which can be used by you for creating scalable and effective APIs, mobile apps, and so forth. In the following paragraphs, we will mention the reasons for selecting Node.js for web app development service in 2021. What exactly is Node.js? Node.js cannot be considered to be a library or framework; however, it is a runtime environment that depends on chrome’s V8 JavaScript engine that helps to apply JavaScript code. Node.js is selected by lots of companies and developers at present since it can support JavaScript and comes with innovative features. Node.js can provide 2-way real-time interaction between the server-side and the client. In this way, the customer and the service provider get an equal share of the workload. Making use of Node.js for web app development service will be the proper choice in case you require a personalized solution having innovative and useful features. Why Node.js should be selected to develop Web apps? 1. Create real-time Web apps This happens to be one significant reason for the developers who want to make the...
Alexander Andersson 2020-02-12 Cyber Security Insecure deserialization is a common vulnerability (OWASP TOP10) that very often leads to arbitrary code execution. Today, I’m going to explain how to turn a seemingly harmless deserialization into code execution. This recently came in handy for me in a penetration test of a PHP/Laravel based application. Before we jump down the rabbit hole, I’ll shortly explain the misconfigurations that allowed me to exploit the vulnerability in the first place. Laravel is weirdly helpful when APP_DEBUG is enabled. It should never be used outside a local dev environment. Errors will not only print out a really fancy error message with the entire stack trace, but also include all environment variables of the application account. That’s not something you want, since environment variables very often contain secrets. In a Laravel application, a variable named APP_KEY is used as the encryption secret for all symmetric encryption within the application. The app key was however not included in the error message. A reasonable explanation would be that it is simply not defined as a environment variable but instead hard coded or inserted in the source code at some point in the pipeline. There was however a few interesting secrets in the environment variables. Among them an AWS key ID and corresponding secret. I knew the target made use of S3 so I put together a script that retrieves directory list of the files I can access. for bucket in $(aws s3 ls | cut -d " " -f 3); do aws s3 ls s3://$bucket --recursive > ./$bucket.txt; done; One of the buckets was particularly interesting, it served...
Credit: CC0 Public Domain A novel machine learning model developed by researchers at Michigan State University suggests that mutations to the SARS-CoV-2 genome have made the virus more infectious. The model, developed by lead researcher Guowei Wei, professor in the departments of Mathematics and Biochemistry and Molecular Biology, analyzed SARS-CoV-2 genotyping from more than 20,000 viral genome samples. The researchers analyzed mutations to the spike protein—a protein primarily responsible for facilitating infection—and found that five of the six known virus subtypes are now more infectious. As with any virus, many mutations are ultimately benign, posing little to no risk to infected patients. Some mutations even reduce infectiousness. But some mutations lead to a more infectious virus. Wei and his team have studied and analyzed mutation patterns and locations for months, tracking changes against the official viral genome sample captured in January. “Knowledge about the infectivity of SARS-CoV-2 is a vital factor for preventive measurements against COVID-19 and reopening the global economy,” Wei said. “A crucial question is what are the ramifications of these mutations to COVID-19 transmission, diagnostics, prevention and treatment.” Viral infection occurs when the spike protein interacts with a human host cell receptor called angiotensin-converting enzyme 2—ACE2 for short. As it relates to ACE2, scientists are concerned about a concept known as binding affinity, or the strength of the binding interaction between the spike protein and host receptor during the initial stage of infection. “Viral infectivity increases if the binding affinity strengthens,” Wei said. “Currently, more than 50 mutations have been found along with the binding interface on the spike proteins receptor-binding domain—RBD for short—which has 194...

As Sri Lanka deals with the second wave of the coronavirus and its economic impacts, a somewhat novel aspect of the new status quo is our increasing dependency on Digital Services. Many of which, we have come to stability, continuity, and convenience. A notable change in this aspect is the shift of key private and government services to digital. However, as we keep shifting our critical operations to cyberspace, we must impress upon and be cautious about the impact of cyber crime. More extremely, we must address the risk of cyber terrorism towards business continuity and national security. In my professional capacity, I have been fortunate to interact with many business leaders, corporate tycoons and Boards of Public Listed companies. Sadly although regular lip service is paid towards cybersecurity; the proof is in the pudding, and our pudding is the stuff of Gorden Ramsey memes. Don’t get me wrong Sri Lanka has capable and talented cybersecurity professionals. Many of whom are regularly picked up by Fortune 500 companies for their excellence. However, it’s the reluctance of top leadership to appreciate and understand the threat of cyber crime & cyber terrorism leaves Sri Lanka vulnerable. Understanding the threat of cyber crime and cyber terrorism Cyber criminals are increasingly setting their sights on targets in Sri Lanka. But are we prepared to deal with this deadly threat? (Image credits: IFEX) Sri Lanka has been already marked as a soft target for cyber criminals. According to the 24th edition of Microsoft’s Security Intelligence Report, Sri Lanka recorded the second-highest malware encounter rate at 9.07 per cent in 2019. Despite a 14% decrease,...
