US National Security Advisor Mike Waltz, who started the now-infamous group chat coordinating a US attack against the Yemen-based Houthis on March 15, is seemingly now suggesting that the secure messaging service Signal has security vulnerabilities.
"I didn’t see this loser in the group," Waltz told Fox News about Atlantic editor in chief Jeffrey Goldberg, whom Waltz invited to the chat. "Whether he did it deliberately or it happened in some other technical mean, is something we’re trying to figure out."
Waltz’s implication that Goldberg may have hacked his way in was followed by a report from CBS News that the US National Security Agency (NSA) had sent out a bulletin to its employees last month warning them about a security "vulnerability" identified in Signal.
The truth, however, is much more interesting. If Signal has vulnerabilities, then China, Russia, and other US adversaries suddenly have a new incentive to discover them. At the same time, the NSA urgently needs to find and fix any vulnerabilities quickly as it can—and similarly, ensure that commercial smartphones are free of backdoors—access points that allow people other than a smartphone’s user to bypass the usual security authentication methods to access the device’s contents.
