I love how San Francisco’s metro system responded to its ransomware attacker

“Considering paying was never an option.”

Backups - the best defence against ransomware (and other risks) | Graham Cluley

After the ransomware attack that messed up the San Francisco Muni Metro’s ticketing machines last weekend, things got back up and running again pretty quickly.

As SF Gate reports, Muni refused to negotiate with their attacker, preferring to restore from a backup instead:

For all Muni Metro passengers knew, the free rides they were getting Friday night and Saturday were a holiday gift from the transit system. Little did they know Muni was under attack from a hacker trying to squeeze $73,000 in ransom to unlock the agency’s computer systems.

Muni refused to pay up. Instead, officials shut down the system’s ticket machines, threw open the fare gates as a precautionary move, and contacted the Department of Homeland Security and their own technology division to contain the attack, they said.

“Considering paying that ransom was never an option,” said Paul Rose, an MTA spokesman.

Ransomware message

If you have a secure backup, and if you have the systems in place to restore that backup in a safe, prompt fashion, then you shouldn’t need to ever consider paying the criminal who is attempting to extort money from you.

Of course, you need to make sure that you keep your backup safe. It may be that you wish to keep it at a different physical location, and you definitely don’t want to risk letting a ransomware infection hit your backup as well as your regular computers.

And remember this, as I explain in my video, ransomware isn’t the only reason you should have backups. Backups save your bacon when your hard drives fail, if you accidentally delete your important files, if your computer is stolen or lost, or if there your premises suffer a fire, flood or coffee spill.

Backups make sense. Sensible people make backups.

    He is right, of course. Backups are important. SECURE backups! Now I wish software companies would make backup software flexible enough to do all he describes and work with multiple partitions and virtual machines!

    'Backups make sense. Sensible people make backups.'

    Therein lies the problem: most people aren't sensible.
