Voice Phishing Scams Are Getting More Clever (krebsonsecurity.com) 201

Security researcher Brian Krebs highlights several clever methods scammers are using to obtain your personal information. In one example, someone used a fully-automated voice to try and scam "a cybersecurity professional with more than 30 years of experience" by greeting him with a four-note AT&T jingle, "followed by a recorded voice saying AT&T was calling to prevent his phone service from being suspended for non-payment."

"It then prompted me to enter my security PIN to be connected to a billing department representative," Jon said. "My number was originally an AT&T number (it reports as Cingular Wireless) but I have been on T-Mobile for several years, so clearly a scam if I had any doubt. However, I suspect that the average Joe would fall for it." Krebs reports of another, more sophisticated scam attempted on Matt Haughey, the creator of the community Weblog MetaFilter and a writer at Slack: Haughey banks at a small Portland credit union, and last week he got a call on his mobile phone from an 800-number that matched the number his credit union uses. Actually, he got three calls from the same number in rapid succession. He ignored the first two, letting them both go to voicemail. But he picked up on the third call, thinking it must be something urgent and important. After all, his credit union had rarely ever called him. Haughey said he was greeted by a female voice who explained that the credit union had blocked two phony-looking charges in Ohio made to his debit/ATM card. She proceeded to then read him the last four digits of the card that was currently in his wallet. It checked out. Haughey told the lady that he would need a replacement card immediately because he was about to travel out of state to California. Without missing a beat, the caller said he could keep his card and that the credit union would simply block any future charges that weren't made in either Oregon or California.

This struck Haughey as a bit off. Why would the bank say they were freezing his card but then say they could keep it open for his upcoming trip? [...] The caller then read his entire home address to double check it was the correct destination to send a new card at the conclusion of his trip. Then the caller said she needed to verify his mother's maiden name. The voice in his head spoke out in protest again, but then banks had asked for this in the past. He provided it. Next she asked him to verify the three digit security code printed on the back of his card. Once more, the voice of caution in his brain was silenced: He'd given this code out previously in the few times he'd used his card to pay for something over the phone. Then she asked him for his current card PIN, just so she could apply that same PIN to the new card being mailed out, she assured him. Ding, ding, ding went the alarm bells in his head. Haughey hesitated, then asked the lady to repeat the question. When she did, he gave her the PIN, and she assured him she'd make sure his existing PIN also served as the PIN for his new card. Haughey said after hanging up he felt fairly certain the entire transaction was legitimate, although the part about her requesting the PIN kept nagging at him.
Long story short, two fradulent charges were made on his account totaling $3,400. "People I've talked to about this say there's no way they'd fall for that, but when someone from a trustworthy number calls, says they're from your small town bank, and sounds incredibly professional, you'd fall for it, too," Haughey said.

When the telephone was invented, you simply COULD NOT use the device independent of the monopolistic phone company. When the television was invented, you just COULDN'T stick an antenna out the window and watch your neighbor's 16 mm home movies. You had to use a BROADCASTING company! I tried to change my Gillette razor blades the other day - I COULD NOT BELIEVE I had to buy expensive "Gillette" razors only! The reasons why TV, telephones, and even razors simply work, as opposed to being a consumer nightmare, is because they are based on proprietary models and are consumer goods, not hackers' tools. Apple has tiny, fragile devices that it does not claim to be PCs (or PCs for the rest of us). As others have said, if you don't want an iPad/Touch/phone, don't buy one. Try a Kindle. Oh, wait...

They're probably just going to monitor heart rate to optimize aerobic exercise. At a certain point if your heart is beating too fast you'll end up in anaerobic mode. http://www.americanheart.org/presenter.jhtml?identifier=4736

Not exactly. The heart muscle itself never runs in "anaerobic mode", which means without oxygen. Anaerobic + heart = death. Death to at least the part of the heart that is deprived of oxygen, or to the person itself it the area of damage is big enough and/or the heart muscle death includes damage to the conduction system (causing an arrythmia, usually ventricular tachycardia). Peripheral muscles (extremities) OTOH can work without oxygen, and function "anaerobically" for a limited time, at the expense of build up of lactic acid (the production of which precedes the requirement for oxygen), leading to peripheral muscle cramps and eventually failure. You can stress yourself during a workout of the legs, say, until they are painfully, crampingly working anaerobically ("anaerobic mode") but it is not correct to say that your body (and certainly not your heart) is running "in anaerobic mode". Monitoring the heart rate during an aerobic exercise such as running is a way to measure cardiovascular and optimize fitness, as you (and the AHA source you quote) correctly state. The rate of your heart, however, tells nothing about whether your leg muscles are running anaerobically.
