In the very first days that the Russia Ukraine war started, I warned you about10 Russia-Ukraine consto expect. We’re already seeing evidence of those scams in action. Be sure you’re keeping your digital guard up.

Misinformation and misleading posts are slamming social media, too.Here are my tricks to spotting fake Russian accounts and posts.

As sanctions increase and Russia’s tactics intensify, it’s easy to think that you will not be affected aside from high gas prices. This idea is exactly what will get you into trouble—time to wake up.

In 2020, Russian hackers invaded several federal government agencies, including the nuclear weapons agency. That’s small potatoes of what could come. A Russian attack on our fiber optic cables or satellites would take down a ton of critical sectors, like internet traffic, banking, GPS, water treatment facilities, power plants, and the power grid.

Many cybersecurity experts predict large-scale Denial of Service attacks. This attack swamps a website with trillions of pings. The website is so busy answering each ping that it can’t respond to anything else. If this happens, government and private industry could take days or even months to sort out.

Wait, there’s more. Russia could launch phishing and other attacks to plant dangerous malware and ransomware on business and individual computers and networks.

Our minds jump to the worst-case scenario in times of distress. Say your internet goes out. Before blaming a large-scale attack, make sure the problem isn't closer to home.

Nominate one person in your family (maybe that person is you) to check in regularly. Maybe it's once a day; perhaps it's once a week.

If there's no cell connection, but your internet is working, use your texting app, Facebook Messenger, WhatsApp, or another messaging option to keep in touch. Work out with your family and friends on the chosen platform ahead of time. The last thing you want to discover is a series of panicked WhatsApp messages hours later when you've been trying to communicate via Facebook Messenger.

Know that texting will often work even when cellular lines are jammed.
