An attack on all e-commerce should have the effect of enabling an attacker to impersonate any server – which is far from reality here. However, this finding does bring a very important issue in generating random numbers and in also generating RSA keys that are not “weak keys”. The software or hardware used to generate keys should be tested against known weaknesses at all times, and customers should ask vendors questions about the process they used to test their cryptographic software. Of course, using other strong cryptographic methods is also a good idea – but also if the keys and random numbers are generated correctly.
