Multiple deployed satellite communications (SATCOM) products have security flaws, according to IOActive researcher Ruben Santamarta, who will present research in the field Wednesday at the cybersecurity conference Black Hat.

The systems are used in everything from airplane in-flight WiFi and entertainment systems to communications on ships. Santamarta found vulnerable systems in both.

"We are talking about major airlines and fleets."
— Santamartato to Axios

Why it matters: Hacking an in-flight WiFi system can't crash a plane — that's a different system. But think about the damage a hacker could cause to an airline by sending an alert to in-flight entertainment systems to prepare for a crash landing.

What was discovered: While IOActive had presented on security problems in device software, it hadn't previously checked the prevalence of the flaws in the real world.

  • "In 2014, those scenarios were theoretical. After four years, we’ve proved they are real," Santamarta told Axios.
  • Santamarta also discovered ways a hacked system could be weaponized to exert harmful radio frequency broadcasts.
  • The 2014 presentation found a bevy of problems in SATCOM, including flawed protocols, poor encryption and hard coded passwords.

Who it effects: IOActive found accessible systems in NATO conflict zones, where SATCOM is used for sending communications to a remote region.

  • Those systems include at least one major airline carrier being kept secret until the presentation.
  • The firm found some systems at sea that had been infected in malware, although it was unclear whether that was a targeted attack.

Trump's legacy is shaped by his narrow interests

President Trump's policy legacy is as much defined by what he's ignored as by what he's involved himself in.

The big picture: Over the past four years, Trump has interested himself in only a slim slice of the government he leads. Outside of trade, immigration, a personal war against the "Deep State" and the hot foreign policy issue of the moment, Trump has left many of his Cabinet secretaries to work without interruption, let alone direction.

AI and automation are creating a hybrid workforce

Illustration: Annelise Capossela/Axios

AI and automation are receiving a boost during the coronavirus pandemic that in the short term is creating a new hybrid workforce rather than destroying jobs outright.

The big picture: While the forces of automation and AI will eliminate some jobs and create some new ones, the vast majority will remain but be dramatically changed. The challenge for employers will be ensuring workforces are ready for the effects of technology.
