Underlying security flaws from code copied from code libraries are in thousands of apps, according to new research from cybersecurity firm CheckPoint. Wired reported that it is causing big problems on Android.

“There are a lot of vulnerabilities out there in applications,” says Yaniv Balmas, head of cyber research at Check Point. “Some of these vulnerabilities are not specifically in applications, but they are found in code libraries. Modern applications use dozens or hundreds of these libraries to operate.” Code libraries (often known as software libraries) allow developers without expertise in specific areas, such as Java Script, to use code that’s already been created. Researchers at Check Point say they have identified existing code libraries that contained vulnerabilities and then compared them to apps scraped from the Play Store. The company says it regularly checks Android apps for its security teams to look for current threats.

All major carriers are going to have 5G networks by 2020, Qualcomm President Cristiano Amon told Yahoo Finance. Given we’re mere weeks away from the new year, that seems a bold prediction. I assume he meant the carriers will have the capability at some point in 2020, not right at the start.

Next-generation 5G wireless connectivity is coming — in fact, it’s available now in some small pockets in major U.S. cities right now. According to Qualcomm (QCOM) President Cristiano Amon, the successor to our current 4G LTE wireless networks will be up and running in all metropolitan areas by next year. “We are at the very beginning of a new technology transition, and like with every technology transition, networks have to be built, you have to have coverage,” Amon told Yahoo Finance’s On The Move on Wednesday. “However, what is great about this time is that we accelerated 5G by a year, and the device ecosystem is ready.” But it will take time before 5G reaches the ubiquity of today’s 4G LTE connections.
