The U.S. government's commitment to the Vulnerabilities Equities Process came after significant lobbying by US technology companies, who risk losing their share of the global market over real and perceived hidden vulnerabilities. The government stated that it would disclose all pervasive vulnerabilities discovered after 2010 on an ongoing basis.
"Year Zero" documents show that the CIA breached the Obama administration's commitments. Many of the vulnerabilities used in the CIA's cyber arsenal are pervasive and some may already have been found by rival intelligence agencies or cyber criminals.
As an example, specific CIA malware revealed in "Year Zero" is able to penetrate, infest and control both the Android phone and iPhone software that runs or has run presidential Twitter accounts. The CIA attacks this software by using undisclosed security vulnerabilities ("zero days") possessed by the CIA but if the CIA can hack these phones then so can everyone else who has obtained or discovered the vulnerability. As long as the CIA keeps these vulnerabilities concealed from Apple and Google (who make the phones) they will not be fixed, and the phones will remain hackable.
The same vulnerabilities exist for the population at large, including the U.S. Cabinet, Congress, top CEOs, system administrators, security officers and engineers. By hiding these security flaws from manufacturers like Apple and Google the CIA ensures that it can hack everyone &mdsh; at the expense of leaving everyone hackable.
