A security researcher was awarded a bug bounty of $107,500 for identifying security issues in Google Home smart speakers that could be exploited to install backdoors and turn them into wiretapping devices.

The flaws “allowed an attacker within wireless proximity to install a ‘backdoor’ account on the device, enabling them to send commands to it remotely over the internet, access its microphone feed, and make arbitrary HTTP requests within the victim’s LAN,” the researcher, who goes by the name Matt, disclosed in a technical write-up published this week.

In making such malicious requests, not only could the Wi-Fi password get exposed, but also provide the adversary direct access to other devices connected to the same network. Following responsible disclosure on January 8, 2021, the issues were remediated by Google in April 2021.

One afternoon in the fall of 2019, in a grand old office building near the Arc de Triomphe, I was buzzed through an unmarked door into a showroom for the future of surveillance. The space on the other side was dark and sleek, with a look somewhere between an Apple Store and a doomsday bunker. Along one wall, a grid of electronic devices glinted in the moody downlighting—automated license plate readers, Wi-Fi-enabled locks, boxy data processing units. I was here to meet Giovanni Gaccione, who runs the public safety division of a security technology company called Genetec. Headquartered in Montreal, the firm operates four of these “Experience Centers” around the world, where it peddles intelligence products to government officials. Genetec’s main sell here was software, and Gaccione had agreed to show me how it worked.

He led me first to a large monitor running a demo version of Citigraf, his division’s flagship product. The screen displayed a map of the East Side of Chicago. Around the edges were thumbnail-size video streams from neighborhood CCTV cameras. In one feed, a woman appeared to be unloading luggage from a car to the sidewalk. An alert popped up above her head: “ILLEGAL PARKING.” The map itself was scattered with color-coded icons—a house on fire, a gun, a pair of wrestling stick figures—each of which, Gaccione explained, corresponded to an unfolding emergency. He selected the stick figures, which denoted an assault, and a readout appeared onscreen with a few scant details drawn from the 911 dispatch center. At the bottom was a button marked “INVESTIGATE,” just begging to be clicked.

I think communication with AI and each other will also be wireless so discoveries like this are important.

CityU

A research team led by a scientist at CityU has resulted in an innovative, game-changing antenna. This revolutionary invention allows unprecedented control of the direction, frequency, and intensity of its signal beam emission. On top of that, this antenna is invaluable for 6G wireless communications applications such as ISAC sensing and communication integration.

SpaceX launched the first batch of a new generation of Starlink satellites into orbit early Wednesday (Dec. 28) and nailed a rocket landing at sea to mark a record 60th flight of the year.

A Falcon 9 rocket topped with 54 upgraded Starlink internet satellites — the first generation 2 (Gen2) versions of the SpaceX fleet — lit up the predawn sky with a smooth launch at 4:34 a.m. EST (0934 GMT) from the Cape Canaveral Space Force Station in Florida.

Dec 26 (Reuters) — SpaceX Chief Executive Elon Musk said on Monday that the company is now close to having 100 active Starlinks, the firm’s satellite internet service, in Iran, three months after he tweeted he would activate the service there amid protests around the Islamic country.

Musk said, “approaching 100 starlinks active in Iran”, in a tweet on Monday.

The billionaire had said in September that he would activate Starlink in Iran as part of a U.S.-backed effort “to advance internet freedom and the free flow of information” to Iranians.

As computer scientists tackle a greater range of problems, their work has grown increasingly interdisciplinary. This year, many of the most significant computer science results also involved other scientists and mathematicians. Perhaps the most practical involved the cryptographic questions underlying the security of the internet, which tend to be complicated mathematical problems. One such problem — the product of two elliptic curves and their relation to an abelian surface — ended up bringing down a promising new cryptography scheme that was thought to be strong enough to withstand an attack from a quantum computer. And a different set of mathematical relationships, in the form of one-way functions, will tell cryptographers if truly secure codes are even possible.

Computer science, and quantum computing in particular, also heavily overlaps with physics. In one of the biggest developments in theoretical computer science this year, researchers posted a proof of the NLTS conjecture, which (among other things) states that a ghostly connection between particles known as quantum entanglement is not as delicate as physicists once imagined. This has implications not just for our understanding of the physical world, but also for the myriad cryptographic possibilities that entanglement makes possible.
