🚢 Ahoy, Monday! SOS is a maritime term that made its way into our tech, like iPhone’s Emergency SOS Mode. Today’s trivia: What does SOS stand for? Is it, Save our Ship, Sink our Ship, Save our Souls or nothing at all? Answer at the end, as always!

Picture a hacker. Did you see a shadowy figure in a hoodie typing in password after password? Hate to break it to ya, but they’re a lot smarter than that. (Though I can’t say either way about the hoodies.) 

Hackers are jumping on the artificial intelligence (AI) bandwagon and upping their game. Get this: AI service PassGAN cracked 51% of common passwords in less than a minute. Let’s take a look at other hacker tools so you can stay safe.

4 ways hackers break into your accounts

⏱️ Brute-forcing: A special program enters different combinations of letters, numbers and symbols. It’s fast! A hacker can try up to 100 billion possible passwords per second.

📕 Dictionary attack: Brute-forcing, but adding words from the dictionary, company names and sports teams to speed things up.

🦃 Credential stuffing: Someone takes one of your breached accounts and tries that email and password combo across different accounts and websites.

🎣 Phishing: A scammer convinces you to click a link to a bogus site, then you (willingly) put in your login details. 

And, even if you do everything right, there’s another thing working against you …

They create free software that anyone can download and improve. A few standard options for cracking passwords have some pretty funny names: John the Ripper, Hashcat and Ophcrack.

➡️ Bottom line: What can you do about it?.

• Longer is better. An eight-character password comprising only uppercase and lowercase letters takes 22 minutes to crack. A 12-character password that includes symbols, too? 34,000 years.
• Use fake words, extra characters and oddball phrases.
• Never reuse a password, even if it’s been out of circulation for a while. 
• Triple check you’re on the real site before you enter your password.
• If a site lets you get away with “password” or “123456,” step away. All my passwords are protected by amnesia.

✅ I know. Passwords stink. I have a few more smart rules here to make it easier to stay safe.

eBay strategy revealed: A new study analyzed 25 million transactions. When bidding, it’s best to use a round percentage of the asking price. Say a seller wants $44. You’ll win the bid at $22 or 50% more often than had you bid $24 or 54%. I’m selling my John Lennon collection on eBay. Imagine all the pay pal.

🧪 Google Beta list: Test Google’s AI Search tools before they go public. Go to google.com and look for the little beaker icon in the top right corner. Click it, then choose “Join Waitlist” on the next page. You’re in.

$500 flat iron: Dyson’s cordless Airstrait uses hot air instead of metal plates, so it doesn’t damage hair. It’s powered by the 27-millimeter Hyperdymium motor, with a 13-blade rotor spinning at 106,000 RPM. The final touch: Glass bead “thermistors” to make sure the air doesn't get too hot. And I’m still over here burning my forehead with a curling iron.

Spot the AI video: Smart tipoffs from the BBB. Look for unnatural body language and strange shadows, blurs or light flickers. And listen closely for choppy sentences or weird word inflection.

Wristy business: Facebook is killing its Messenger app for Apple Watch. If you use it, you’ll still see notifications, but you can’t reply. Imagine if Apple called it the “iWatch?”

💳 Cha-ching: The cards formerly known as Amazon Prime Rewards Visa Signature Card and Amazon Rewards Visa Signature Card have new names. For the Prime Visa, yup, you need a Prime membership; get 5% back on travel purchases, plus the standard 5% back on Amazon. The Amazon Visa is a no-Prime option with lower payouts.

No more taxiing: You can now book a Lyft to pick you up as soon as you land at the airport. Just be sure to check the fees. Uber has it, too, and I was shocked to see a $25 surcharge added.

Have an idea for an app? Go for it. Seriously. Apple says 90% of its developers are small, with fewer than 1 million downloads and less than $1 million a year in revenue. And as a group, their revenue grew by 87% in the U.S. over the last couple of years.

💸Bonus: Apple charges a 30% commission to big developers. The little guys only pay 15% of revenues.

Hot app categories

The fastest-growing apps are health, fitness and lifestyle oriented. I checked out the top App Store downloads. Think you have an idea that can beat these? 

• Waterllama: Get in your daily ounces to fill in the cartoon llama. It’ll remind you to drink.
• Pool-Calculator: This does all the math when you need to treat your pool or hot tub. Genius. 
• FaceYoga: Not sure if it can really erase wrinkles or get rid of a double chin, but hey, a lot of people are willing to download it to find out.

I was thinking about developing a dating app for lumberjacks. I’d call it “Timber.”

Did you take off your smartwatch last time you sweat or took a potty break? Didn’t think so. Wearable gadgets host 30 times more bacteria than your toilet. Gross! Here’s how to clean your smartwatch.

• Turn it off and remove any straps attached to it. 
• Take a small amount of rubbing alcohol to a cloth or cotton swab. Use it to wipe the screen and the exterior of the watch. Avoid the straps!
• Let the watch air dry completely before reattaching the straps and turning it back on.

✂️ Better way: Use a UV sanitizing box to kill bacteria on your smartwatch. Toss your phone and keys in while you’re at it.

The Bible has a whole book dedicated to coffee: Hebrews.

🆘 The answer: Nothing at all. SOS is a Morse code distress signal. The original version used by the British was CQD ("seeking you, distress" or "all stations, distress”). The call was standardized to the simpler SOS in 1906 at the International Telegraphic Radio Conference.

These days, kids use it to express their dismay in a funny way. To “Harry Styles just got a new girlfriend,” one might reply, “Sos noooooo!”
