Countries toiled for years and spent billions of dollars to build elaborate facilities that would allow them to join the exclusive club of nations that possessed nuclear weapons.
Getting into the cyberweapon club is easier, cheaper and available to almost anyone with cash and a computer.
A series of successful computer attacks carried out by the U.S. and others has kicked off a frantic and destabilizing digital arms race, with dozens of countries amassing stockpiles of malicious code. The programs range from the most elementary, such as typo-ridden emails asking for a password, to software that takes orders from a rotating list of Twitterhandles.
The proliferation of these weapons has spread so widely that the U.S. and China—longtime cyber adversaries—brokered a limited agreement last month not to conduct certain types of cyberattacks against each other, such as intrusions that steal corporate information and then pass it along to domestic companies. Cyberattacks that steal government secrets, however, remain fair game.
This comes after other countries have begun to amass cyberweaponry on an unprecedented scale. Pakistan and India, two nuclear-armed rivals, regularly hack each other’s companies and governments, security researchers said. Estonia and Belarus are racing to build defensive shields to counter Russia. Denmark and the Netherlands have begun programs to develop offensive computer weapons, as have Argentina and France.
