Slashdot: Plasma Thrusters For Small Satellite Systems Hit Hyper Drive

Plasma Thrusters For Small Satellite Systems Hit Hyper Drive
Published on August 31, 2019 at 12:30PM
Greg Nichols reporting for ZDNet: A company that makes propulsion systems for small satellites, Orbion Space Technology, has announced $9.2M in Series A funding. The round was led by Material Impact, a venture firm focused on translating early stage materials technologies into products and companies. Orbion has developed a very Star Trek-sounding technology that may prove to be a crucial component of an emerging New Space industry, the first-ever Hall-effect plasma thrusters for small satellites, dubbed the Aurora system. The company plans to use the capital from this round to support mass production of its thrusters. Hall-effect plasma thrusters are a type of ion drive in which a propellant is accelerated by an electric field. The technology has been around since the 1960s, and Hall-effect thrusters were in use on Soviet satellites between 1972 and 1990. What's new is the size of the thrusters, as well as the size of the satellites they power, which are variously dubbed smallsats, microsatellites, or nanosatellites. As components and sensing technology has gotten smaller, and with the diversity of computing and sensing components available off-the-shelf, this new breed of satellite is cheap to build and lightweight, further reducing payload costs. That's opening up the possibility of launching communications and satellite arrays to companies and organizations that have never had that option.

Slashdot: US Army Soldier Arrested In AT&T, Verizon Extortions

US Army Soldier Arrested In AT&T, Verizon Extortions Published on January 01, 2025 at 02:35AM An anonymous reader quotes a report from KrebsOnSecurity: Federal authorities have arrested and indicted a 20-year-old U.S. Army soldier on suspicion of being Kiberphant0m, a cybercriminal who has been selling and leaking sensitive customer call records stolen earlier this year from AT&T and Verizon. As first reported by KrebsOnSecurity last month, the accused is a communications specialist who was recently stationed in South Korea. Cameron John Wagenius was arrested near the Army base in Fort Hood, Texas on Dec. 20, after being indicted on two criminal counts of unlawful transfer of confidential phone records. The sparse, two-page indictment (PDF) doesn't reference specific victims or hacking activity, nor does it include any personal details about the accused. But a conversation with Wagenius' mother -- Minnesota native Alicia Roen -- filled in the gaps. Roen said that prio...

US Army Soldier Pleads Guilty To AT&T and Verizon Hacks Published on February 20, 2025 at 01:31AM Cameron John Wagenius pleaded guilty to hacking AT&T and Verizon and stealing a massive trove of phone records from the companies, according to court records filed on Wednesday. From a report: Wagenius, who was a U.S. Army soldier, pleaded guilty to two counts of "unlawful transfer of confidential phone records information" on an online forum and via an online communications platform. According to a document filed by Wagenius' lawyer, he faces a maximum fine of $250,000 and prison time of up to 10 years for each of the two counts. Wagenius was arrested and indicted last year. In January, U.S. prosecutors confirmed that the charges brought against Wagenius were linked to the indictment of Connor Moucka and John Binns, two alleged hackers whom the U.S. government accused of several data breaches against cloud computing services company Snowflake, which were among the ...

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.
