Craig Timberg:

Experts say it's increasingly clear that SS7, first designed in the 1980s, is riddled with serious vulnerabilities that undermine the privacy of the world's billions of cellular customers.

A single carrier in Congo or Kazakhstan, for example, could be used to hack into cellular networks in the United States, Europe or anywhere else.

Peter Singer:

The attackers wonderfully understand the American psyche. This was a hack, but call it 'cyber' and 'terrorism,' and we lose our shit. There's no other way to put it.

KABC7 Los Angeles:

An American Airlines flight from LAX to London was delayed Sunday after concerns over the name of a WiFi hotspot.

Nick Wingfield:

In April, a drone crashed trying to airlift a payload of cellphones, marijuana and tobacco over the walls of a maximum-security prison. Authorities are unsure whether drone operators made earlier undetected drops.

Marc Rogers:

Let's face it -- most of today's so-called "cutting edge" security defenses are either so specific, or so brittle, that they really don't offer much meaningful protection against a sophisticated attacker or group of attackers.

FBI:

North Korea's attack on SPE reaffirms that cyber threats pose one of the gravest national security dangers to the United States.

Sony reported this incident within hours, which is what the FBI hopes all companies will do when facing a cyber attack. The FBI stands ready to assist any US company that is the victim of a destructive cyber attack or breach of confidential business information.

Shawn Henry, FBI executive assistant director [in 2012]:

I don't see how we ever come out of this without changes in technology or changes in behavior, because with the status quo, it's an unsustainable model. Unsustainable in that you never get ahead, never become secure, never have a reasonable expectation of privacy or security.

Ted Cruz:

If you can frame the narrative, you win.
