Remember when there was a fire alarm every hour or so during last year’s finals?

Dallas just had a dose of that, except for Dallas, it brought national security into question and had the entire city on lockdown.

On April 7, a hacker triggered all 156 emergency alarms in Dallas. The alarms blared from 11:40 p.m. until  1:20 a.m. Citizens of Dallas progressed from a stage of alarm, to curiosity, to just plain annoyance.

Just like the constant fire alarms at Cal (but with less drugs and trash), a single person managed to completely waste the time of thousands of people.

Obviously, people spazzed the heck out when tornado warnings started blaring in the middle of the night with not a cloud in sight. 911 received 4,000 calls until 3 a.m., and the excess number of calls caused an overload on the servers and began to melt the system.

Thousands of posts flooded social media as Dallas residents wondered what was going on.

Authorities have inferred that the hacker simply calculated on what frequencies the alarm system communicates  and then spammed that frequency into the receiver to trigger the alarms.

An unnamed official came forward and admitted that the system does not encrypt their frequencies sent to trigger alarms, so it wasn’t really a challenge for someone to mess with the entire city with a push of a button.

On the bright side, even if everyone was about to lose their minds, the hackers did manage to check up on the inefficiency of the alarm system and bring awareness to the current threat on national safety. Whoop-de-doo.

In 2013, an unnamed security firm tested on the Federal Emergency Management Agency’s Integrated Public Alert and Warning System  and discovered that it was extremely vulnerable to forced hack attempts.

So in case you didn’t feel unsafe enough, the official national security system can be hijacked.

More recently, last month the organization Wikileaks managed to expose a huge number of cyber weapons that the CIA uses to hack and spy on American citizens. The weapons had names like “Medusa” and “Assassin.”

If you wanted a codename for something dangerous, I suggest something that doesn’t sound dangerous, like “dog” or “newborn baby.”
