Grasshopper and Ant and the App Store

One day, at the beginning of spring, Grasshopper and Ant each got a new smartphone. They both chose the same make and model. They even had the same cell carrier with the same data plan. The only difference, apart from Grasshopper being of the order Orthoptera and Ant being of the order Hymenoptera, was their general attitude towards security in general and app permissions in particular.

Ant was very security-conscious. He switched off his GPS and other location services, activating them only when he needed them, and then turned them off again right away. When he loaded an app, he read carefully over what permissions it required. Any game, for example, that needed access to his contacts list was right out, as were other apps that seemed to need access to data that seemed unrelated to the primary function of the app. As a result, Ant did not have many apps on his smartphone. He did load quite a lot of music and ebooks on his phone for entertainment, but refused even to install Facebook or Twitter. He was just that kind of guy.

Grasshopper, on the other hand, loaded all kinds of games and apps on his phone. He didn’t care what permissions they wanted, he would load them up. He would load them up, use them for a while, and then forget about them and load more apps. Ant thought Grasshopper was out of control. Grasshopper thought Ant was a party pooper.

It may not surprise you, dear reader, to discover that Ant also checked his credit card statements regularly while Grasshopper had a more carefree attitude towards personal finance.

At any rate, all through the spring and summer and into the fall, Grasshopper combined hundreds and thousands of shapes into rows of three or more, built up digital armies and empires, and used every emoji that he could find. Ant, meanwhile, kept to his books and his music.

As the first snow of winter fell to the ground, Grasshopper got a letter in the mail that many of his credit cards had been maxed out. Grasshopper didn’t think that he’d made that many in-game purchases, so he checked over his recent statements in greater detail. He was shocked to discover a number of very large purchases on his account for goods that he had never received. Not knowing what to do, he went to Ant’s house and begged Ant for a few scraps of food to tide him over through the winter, for he had no means to purchase provisions, what with his maxed-out cards.

Ant chided Grasshopper, “I’ll give you nothing, foolish Grasshopper!”

Grasshopper felt like a melting snowflake. “That’s a bit harsh, Ant. Where is your pity? Your sense of charity?”

Ant growled on, “Look, those are obviously fraudulent charges on your accounts. Just call the credit company and have them removed. You’ll have to cancel all your cards, but-”

“Oh! Whatever will I do without credit cards?”

“Well, you could let me finish my sentences, for a start. As I was saying, cancel the cards, BUT you will get new ones in a few days. That’s how it works out. It’s possible that the charges were just simple fraud from one of your apps being a front for bandits or from you not using secure sites for purchases.”

Grasshopper began to dance a little. “Why, that is marvelous news! All will be well!”

“Quit interrupting me. And you could stand to be a little less manic-depressive, if possible. All will not be well if this is part of an identity theft. There have been a number of major breaches of late, and I’m sure at least one of the million apps you’ve downloaded was a headline. You should get a credit report and see if any accounts in your name have been opened up recently – and if those accounts also have maxed out cards. Then there’s a follow up with the IRS to see if someone files a fraudulent tax return in your name, to get a government refund sent to them. That’s just the start, really.”

Grasshopper was silent.

Ant said, “I’m done. You won’t interrupt me if you say something now, if-”

“Oh! Goodness! Identity theft! Whatever shall I do? Please, brother Ant, do you have an identity I can borrow to see me through the cold of the winter?”

“It doesn’t work that way, Grasshopper. I recommend you check out articles on what to do if you’re a victim of identity theft.”

“Why can’t you tell me more, O wise Ant?”

“Because I’ve never had my identity stolen! I don’t know what else to do, as I’ve never had to know!”

“Why haven’t you had your identity stolen?”

“Well, for starters, I’m careful about the apps I load on my phone. Now, do you mind? I’m with people, here.”

Grasshopper bid farewell and trudged home, sadder but wiser. One by one, he started to uninstall all his apps and vowed to never again blithely install a game that needed access to his web history, contacts, location, calendar, phone records, media folders, and core OS files.

Fox and Crow and the Strong Password

Once upon a time, Crow had a rather nice hunk of cheese. Rather than hold it in his beak, which would leave it vulnerable any time Crow wanted to talk, Crow placed it in a vault and secured the vault by means of a very strong password.

Now, Fox happened to be walking past Crow’s tree when he saw the vault in the tree’s branches and a computer system connected to the vault. “There’s something you don’t see every day!” Fox said to himself as he sat under the tree a while to watch what was going on with the vault and the computer, which really stuck out among the leaves and branches of the tree.

Crow noticed that Fox was making general observations. Being a rather clever animal himself, Crow decided to try to get Fox to move along before Fox learned enough to compromise Crow’s security. Crow shouted, “Move it, Fox, or I’ll start throwing acorns at your head!”

Fox replied, “But good sir Crow, I’m only resting in the shade of this lovely tree a moment! Would you deny a fellow woodland creature such a blessing in the heat of the day?”

Crow would have none of that. “There are plenty of trees around here, move your bushy butt!” With that, Crow started to pelt Fox with acorns.

Fox ran away, but was still determined to get at the contents of that vault, whatever they were. Only valuable things go into vaults, and there was a good chance that what was valuable to Crow would also be valuable to Fox. Fox thought of a plan on how to penetrate Crow’s security.

As a first step, Fox went to the nest of a killdeer bird. The nest was on the ground and it held four small eggs, really too small even for Fox to want to make a meal of them. Fox merely placed his paws near the eggs and waited for Killdeer to return.

When Killdeer came back from foraging, she saw Fox near her eggs and immediately pretended to have a broken wing, hoping to draw Fox away from her nest.

Fox would have none of that. “Easy, sister, I’m not falling for the broken wing con you killdeer run. And I’m not interested in eating the eggs. I’ll be happy to leave them alone if you have a simple conversation with Crow on my behalf.”

Killdeer was a little panicked, given how Fox was holding her eggs hostage. “I’ll go to Crow. What do you want me to say?”

A short time later, Killdeer hopped on to a branch in Crow’s tree. She introduced herself. “Hello Crow, I’m a security researcher. I’m checking with folks in this area to see if they’re using strong passwords to secure their valuables.”

Crow puffed up his chest feathers. “I have a very secure password, indeed.”

“Does it include upper and lowercase letters?”

“That it does, and more!”

“Does it include numbers and non-alphanumeric symbols associated with the number keys?”

“That it does, and more!”

“Does it involve a phrase so that you can use the phrase as both a memory aid and as a lengthy password?”

“That it does, and more!”

“Does it involve non-alphanumeric characters not associated with the number keys?”

“That it does, and more! Look, is this going to go on much longer? I got things to do.”

“Oh, that was pretty much my last question, Crow. If all those things are true, then you certainly have a nice, strong password. Although…”

“What?”

“Well, I just don’t know if it’s the strongest password possible. It may be good, but is it the best?”

Crow was a vain fellow and couldn’t stand the thought of his password possibly not being the best. “Well, what’s the best password you’ve heard so far?”

Killdeer said exactly as Fox had instructed her. “*aRRa(ud4B1t35Ar3Pa1nFu|”.

Crow laughed. “That’s only 24 characters! Mine is much better than that!”

Killdeer asked, “Well, what is it?”

Crow cackled out, “,,V4n!7Y_I5-tH3(f1477eREr_()f=7hE_S0u1,,”.

Killdeer nodded, “My! That truly is a great password. It absolutely sounds like the best one, ever!”

Crow nodded proudly. “Told you so.”

Later that night, Fox climbed up Crow’s tree. Red foxes like Fox normally didn’t climb trees, but Fox had watched a few YouTube how-to videos on how to climb trees made by some gray foxes, who themselves are famous for their climbing abilities. Once up the tree, Fox entered Crow’s great password into the computer and was able to access the vault. Although the large hunk of cheese made climbing down difficult, Fox managed the maneuver and made off with his ill-gotten gain.

In the cold morning light that followed the robbery, Crow saw the opened vault and his insides turned ice cold. Too late, he realized that a password is no good at all once someone else knows it.

Tortoise and Hare and the Internet

Once upon a time, Tortoise and Hare both decided to start their own e-commerce firms. Both received roughly the same amount of bank financing, but while Tortoise put some funds towards a firewall, an IPS, and an anti-phishing program, Hare went cheap on his firewall and put everything he had into fancy marketing materials. For storage, Tortoise kept his data on-premises while Hare put all his data into the cloud.

Hare thought he was pretty slick as he started to rack up contracts at a faster pace than Tortoise.

One day, though, a Big Bad Moose pointed his tools at the IP range that included the public addresses of both Tortoise’s and Hare’s firms. The Big Bad Moose didn’t specifically target Tortoise or Hare: their numbers had just come up, so it was their turn to be targeted by the Big Bad Moose. Next week, it would be the Big Bad Duck or the Big Bad Gerbil, or, well, {Big Bad {$SPECIES}} would pretty much define all the evil hackers out there in the land. Point being, there were lots of hackers of all different types, so one shouldn’t be surprised if a Big Bad Moose is trying to pwn servers.

While Hare’s cheap firewall was enough to stop Moose’s general port scan, it didn’t do a thing against Moose’s SQL injection attacks on Hare’s firewall or the spear fishing emails to CarrotFest that Moose sent to people in Hare’s company.

Meanwhile, Tortoise’s IPS caught the SQL injection attacks and his phishing defenses blocked the emails to LettuceCon that Moose had sent to Tortoise’s company. Moose didn’t care. In his work, some attacks worked and some just made one focus on the attacks that worked.

After the Big Bad Moose got some username and password combos for Hare’s network, he was delighted to discover that the RDP port was allowed in from the firewall to servers and desktops inside. Moose used the stolen credentials to get good stuff like financial details and company credit card info, which he then used to buy lots and lots of stuff for himself, particularly big-ticket items like home theater systems that would fetch a pretty good return on eBay in “unopened” condition. Once those transactions had cleared, he sold the credit card numbers.

Big Bad Moose then sold access to Hare’s open relay mail server to a Big Bad Komodo Dragon. Within seconds, millions of spam mails in Bahasa Indonesia were flying through Hare’s mail server, effectively shutting down his business operations. Worse, only a few hours later, Hare’s email server got black-holed. Hare had no idea about what to do to get back into production. Nobody at Hare’s company knew what to do except to shut down the email server, which they did for a day, allowing them to get off the blacklist.

But, as soon as they turned it back on, the Indonesian spam from Big Bad Komodo Dragon came back on, as well. Hare shut down the email server again and called a consulting company to assess the damage. When the consultants found all the penetrations on Hare’s network, they recommended that he flatten all his systems and start over. When Hare looked at the consultants like they were crazy, the consultants showed Hare where his servers were now storing illegal pornography. That got Hare to agree with the consultants.

Meanwhile, Tortoise kept going like business as usual. He even started to get clients that had dropped Hare, due to Hare’s extended outage.

Hare noticed how Tortoise was getting more business and reckoned that his was going to fail soon. Hare made a career change and got into consulting, so that he could share his lessons learned with other small business owners. Whenever he saw another business owner trying to go as fast as possible without putting much emphasis on security, Hare would say, “Not so fast, there, buddy! Let me tell you why slow, steady, and secure can win the race…”
