“We assess with excessive confidence that these exploits had been packaged by a single industrial surveillance firm, Cytrox, and bought to completely different government-backed actors who used them in at the least the three campaigns mentioned beneath,” mentioned Google TAG members Clement Lecigne and Christian Resell.

The federal government-backed malicious actors who bought and used these exploits to contaminate Android targets with spyware and adware are from Egypt, Armenia, Greece, Madagascar, Côte d’Ivoire, Serbia, Spain, and Indonesia, in keeping with Google’s evaluation.

These findings align with a report on Cytrox mercenary spyware and adware printed by CitizenLab in December 2021, when its researchers found the malicious software on the cellphone of exiled Egyptian politician Ayman Nour.

Nour’s cellphone was additionally contaminated with NSO Group’s Pegasus spyware and adware, with the 2 instruments being operated by two completely different authorities purchasers per CitizenLab’s evaluation.

The risk actors deployed exploits focusing on these zero-days in three separate campaigns:

  • Marketing campaign #1 – redirecting to SBrowser from Chrome (CVE-2021-38000)
  • Marketing campaign #2 – Chrome sandbox escape (CVE-2021-37973, CVE-2021-37976)
  • Marketing campaign #3 – Full Android 0-day exploit chain (CVE-2021-38003, CVE-2021-1048)

“All three campaigns delivered one-time hyperlinks mimicking URL shortener providers to the focused Android customers through electronic mail. The campaigns had been restricted — in every case, we assess the variety of targets was within the tens of customers,” the Google TAG analysts added.

“As soon as clicked, the hyperlink redirected the goal to an attacker-owned area that delivered the exploits earlier than redirecting the browser to a reputable web site. If the hyperlink was not energetic, the consumer was redirected on to a reputable web site.”
