Struggle the phish! – Bare Safety

It’s the second week of Cybersecurity Awareness Month 2021, and this week’s theme is an alliterative reminder: Fight the Phish!

Unfortunately, anti-phishing advice often seems to fall on deaf ears, because phishing is an old cybercrime trick, and lots of people seem to think it’s what computer scientists or mathematical analysts call a solved game.

Tic-tac-toe (noughts and crosses outside North America), for example, is a solved game, because it’s easy to create a list of every possible play, and figure out the best possible move from every game position on the list. (If neither player makes a mistake then the game will always be a draw.)

Even games that are enormously more complex have been “solved” in this way too, such as checkers (draughts)…

…and in comparison to playing checkers, spotting phishing scams feels like an easy contest that the recipient of the message should always win.

And if phishing is a “solved game”, surely it’s not worth worrying about any more?
