With the number of web applications out there today, it comes as no surprise that there are just as many vulnerabilities waiting for hackers to discover. Finding those vulnerabilities can be a difficult task, but there are plenty of tools available to make the process easier. While it won't help find any zero-days, web scanners such as Uniscan will detect common vulnerabilities.
When computers have vision but people don't, why not have the former help the latter? That's the gist behind the Cognitive Augmented Reality Assistant (CARA), a new HoloLens app developed by the California Institute of Technology.
They're finally here. Apple announced three new iPhone models at their "Gather Round" event in Cupertino, and they're all absolutely gorgeous phones. With bezel-less screens and polished titanium edges, the iPhone XS, XS Max, and XR are truly marvels of engineering — but perhaps the most impressive design feat Apple pulled off is the fact that two of these models are rated IP68 under the IEC standard 60529.
A simple security flaw can allow an attacker to gain a strong foothold with little effort on their part. When a web application permits remotely hosted files to be loaded without any validation, a whole can of worms is opened up, with consequences ranging from simple website defacement to full-on code execution. For this reason, RFI can be a promising path to obtaining a shell.
Despite its fifth-place finish in our ranking of the best transcriber apps on iOS, Voicera is still worth highlighting due to numerous factors that set it apart from the crowd. Besides being completely free to use on both iPhone and Android, the app's AI-based transcription service performed extremely well in our testing.

Gonorrhea infections reached a peak in 1975, then decreased until 2009, when infection rate started rising and has increased each year since. With the rise of antibiotic resistance, those numbers are only going to get worse — unless we find new treatments against the bacteria.
An older man dies of Zika. A younger man who cares for him catches Zika — but doctors cannot pinpoint how the disease was transmitted. While proximity to the patient is sufficient explanation for the rest of us, for microbe hunters, it is a medical mystery. Why? Zika is not known to transmit from person-to-person casually.
Antibiotics are one of our main weapons against infections. The problem is that many bacteria are becoming resistant to most of the antibiotics we use to treat them, and those 'superbugs' have created an urgent threat to our global health. A research group found a new way to hit a well known bacterial target and have developed a drug to hit it.
Some drivers give Tesla's Autopilot update released this week rave reviews, after version 8.1 has taken longer than expected to live up to Elon Musk's "smooth as silk" Tweet from earlier this year.

Heart disease is the leading cause of death of men and women in the US. Over half a million Americans die from it annually. Atherosclerosis — a build up of plaque in the arteries — is a common feature of heart disease and can be caused by smoking, fats and cholesterol in the blood, diabetes, and high blood pressure.
Natural remedies used through the ages abound, especially in Asian medicine. The willow-leaved justicia plant, found throughout Southeast Asia, has traditionally been used to treat arthritis, but scientists have just discovered it contains an anti-HIVcompound more potent than AZT. AZT was the first drug approved to treat HIV, and is still used in HIV combination therapy today.
Peach trees and other related plants are susceptible to the devastation caused by fire blight, a contagious bacterial disease. Once contracted, infected trees have to be burned to contain the disease and prevent spread to nearby trees. Increasing resistance to antibiotic treatment has sent scientists in search of alternative ways to deal with the bacteria and prevent its catastrophic damage.
