The remote style of attack is more dangerous because an attacker doesn't need to open up the ATMs.

It allows an attacker to gain full control of the ATMs and not only order it to spit out money, but also to silently harvest card data from anyone who uses the machines. It also affects more than just the standalone ATMs vulnerable to the physical attack, and could potentially be used against the kinds of ATMs used by mainstream banks.

Jack said he didn't think he'd be able to break the ATMs when he first started probing them.

Jack said the manufacturers whose machines he studied are deploying software fixes for both vulnerabilities, but added that the prevalence of remote-management software broadly opens up ATMs to hacker attacks.
