In its February threats report, RSA said banking brands from Ireland and Brazil had made the list of the top countries targeted for the first time.
It said this followed the trend in the last few months of South American banks taking up a significant share of the brands targeted.
In February, 188 banking brands were targeted by phishers. RSA said 20 of these brands had not previously been targeted.
The US brands are still the most dominant in the list, with the UK still in second place with 12% of the targeted brands.
