Google pulls virtual assistant ad after user outcry

Google Home users got a surprise on Thursday when their virtual assistants cheerily mentioned that the live-action remake of “Beauty and the Beast” is opening in theaters this weekend.The ad seems to pop up when users ask for a rundown of their day, which kicks off the Home’s “My Day” feature. That feature is supposed to offer users information about the weather, their calendars and relevant news. But at the end of the rundown, the Google Assistant offered the following unsolicited tidbit, according to a video posted to Twitter by Bryson Meunier :“By the way, Disney’s live action 'Beauty and The Beast' opens today,” it says. “In this version of the story, Belle is the inventor instead of Maurice. That rings truer, if you ask me. For some more movie fun, ask me something about Belle.”To read this article in full or to leave a comment, please click here

Details matter when developing an incident response (IR) plan. But, even the most successful IR plans can lack critical information, impeding how quickly normal business operations are restored.This guide from Cybereason takes a closer look at nine of the often forgotten, but important steps that you should incorporate into your IR plan.Preparation across the entire companyGood security leaders should be able to get people from across the company to help develop the IR plan.

At the outset of the Trump presidency, there is considerable uncertainty around what the new administration might mean for tech policy, a deeply complex set of issues that were largely out of view on the campaign trail.As a candidate, Trump did not articulate a tech policy agenda, though he stressed the need for a tougher posture on cybersecurity.[ Related: What to expect from the Trump administration on cybersecurity ]Now in the Oval Office, Trump has a range of areas where he could advance polices that impact the tech sector, from immigration to privacy to curbing regulations on emerging technologies such as drones and health IT applications.To read this article in full or to leave a comment, please click here

Experts divided on value of Cyber National Guard

This past weekend at SXSW, two Congressmen suggested that the U.S. create a cybersecurity reserves system, similar to the National Guard, but the idea has received a mixed welcome from the cybersecurity community.According to House Rep. Will Hurd, a Republican from Texas, a national cybersecurity reserve could help strengthen national security and bring in a diversity of experience. Hurd, who has a degree in computer science from Texas A&M, has served as an undercover CIA officer and has worked as a partner at cybersecurity firm FusionX.He has been pitching the idea of a Cyber National Guard for a while, and has suggested that the government could forgive student loan debt for those who serve. It would also help ensure a cross-pollination of experience between government and industry.To read this article in full or to leave a comment, please click here

Microsoft ends updates for Windows 7/8.1 on new processors

As it promised, Microsoft has stopped issuing updates for Windows 7 and Windows 8.1 users whose PCs run Intel's seventh-generation processors (codename Kaby Lake), AMD's seventh-generation processors (Bristol Ridge), and Qualcomm's 8996 processor or newer. It's also likely that AMD's new Ryzen processor is included in that list. Bristol Ridge is a slightly older processor made on an older core design.Mainstream support for Windows 7 ended on January 2015, but extended support—in other words, patches—is supposed to continue until January 2020. Support for Windows 8.1 runs through next year and support ends in 2023. However, Windows 7 and Windows 8.1 PCs running these new CPUs will not scan for updates or download them from Windows Update. Windows 7 and Windows 8.1 users with new processors who run the Windows Update tool get one of two messages. The first is straightforward: To read this article in full or to leave a comment, please click here

Epoch Rollover: Coming Two Years Early To A Router Near You!

The 2038 Problem

Broken Time? -  Roeland van der Hoorn
Many computer systems and applications keep track of time by counting the seconds from "the epoch", an arbitrary date. Epoch for UNIX-based systems is the stroke of midnight in Greenwich on 1 January 1970.

Lots of application functions and system libraries keep track of the time using a 32-bit signed integer, which has a maximum value of around 2.1 billion. It's good for a bit more than 68 years worth of seconds.

Things are likely to get weird 2.1 billion seconds after the epoch on January 19th, 2038.

As the binary counter rolls over from 01111111111111111111111111111111 to 10000000000000000000000000000000, the sign bit gets flipped. The counter will have changed from its farthest reach after the epoch to its farthest reach before the epoch. time will appear to have jumped from early 2038 to late 1901.

Things might even get weird within the next year (January 2018!) as systems begin encounter freshly minted CA certificates with expirations after the epoch rollover (it's common for CA certificates to last for 20 years.) These certificates may appear to have expired in late 1901, over a century prior to their Continue reading

Yahoo breach exposes the drawbacks of state-sponsored hacking

When governments turn to private hackers to carry out state-sponsored attacks, as the FBI alleges Russia did in the 2014 breach of Yahoo, they're taking a big risk. On the one hand, it gives them a bit of plausible deniability while reaping the potential spoils of each attack, but if the hackers aren't kept on a tight leash things can turn bad. Karim Baratov, the 22-year-old Canadian hacker who the FBI alleges Russia's state security agency hired to carry out the Yahoo breach, didn't care much for a low profile. His Facebook and Instagram posts boasted of the million-dollar house he bought in a Toronto suburb and there were numerous pictures of him with expensive sports cars -- the latest an Aston Martin DB9 with the license plate "MR KARIM."To read this article in full or to leave a comment, please click here

Cornell has a radio for the whole world with software filtering

Researchers at Cornell University have developed a new type of radio-on-a-chip that could mean cheaper, more flexible wireless systems. Smartphone makers could, for example, use the technology to make a single model of each phone that works anywhere in the world.Single-chip radios have become a popular choice for communications hardware in the last decade because most characteristics of the radio are determined through software, not discrete hardware components. For this reason, they are often referred to as software-defined radios.But software can only do so much. In many transceiver devices -- ones that transmit and receive -- an array of filters is needed to protect the sensitive receiver circuity from signals being transmitted. Those signals can be up to a billion times more powerful that the ones being received, so without the filters, the radio would be overwhelmed and useless.To read this article in full or to leave a comment, please click here
