BLUF

A cyber-attack on Yandex—Moscow's biggest taxi company—caused traffic chaos; the Anonymous Collective has claimed responsibility as part of its 'OpRussia' campaign supporting Ukraine.

Summary

Loukia Papadopoulos writing in Interesting Engineering, makes the following points:
  • The cyberattack caused a three-hour traffic jam sending taxis toward Moscow's Hotel Ukraine.
  • The attackers probably bypassed Yandex's security and generated fake pick-up requests.
  • Russia-friendly hackers have previously launched cyber-attacks against Ukrainian government organisations.
