Guarding Against Cyber Attacks Post-Russia Invasion | Weaver

With rising international tensions following Russia’s invasion of Ukraine, organizations of all sizes and in every industry need to be vigilant to protect themselves from cyberattacks. Attackers may not be limited to nation-state affiliates. Bad actors could include independent organized cybercrime groups, such as ransomware gangs, vigilante groups with political motives, or other nefarious actors simply seeking to take advantage of the crisis. Some organizations may be targeted for their public associations (real or assumed), while others may inadvertently be affected due to the indiscriminate nature of an attack (cyber collateral damage), as was the case in 2017 with NotPetya. These “Quick Checks” can help any organization protect itself by detecting, responding to, and recovering from cyber incidents.

You’ve Got This

• Review attack surface & 3^rd party connections
• Incident response plan
  • Put your hands on it & update

  • Print it out and put it in multiple locations (OoB cloud storage as well)
• Double-check backups
  • Immutable
  • Offline/out-of-band

Think Through

• What communication can you prepare in advance?

  • EDR
• Do you have all the logs you need?
  • For the right length of time?
