Hackers Account For 90 Percent of Login Attempts At Online Retailers (qz.com)

Hackers account for 90% of of e-commerce sites' global login traffic, according to a report by cyber security firm Shape Security. They reportedly use programs to apply stolen data acquired on the dark web -- all in an effort to login to websites and grab something of value like cash, airline points, or merchandise. Quartz reports: These attacks are successful as often as 3% of the time, and the costs quickly add up for businesses, Shape says. This type of fraud costs the e-commerce sector about $6 billion a year, while the consumer banking industry loses out on about $1.7 billion annually. The hotel and airline businesses are also major targets -- the theft of loyalty points is a thing -- costing a combined $700 million every year.

The process starts when hackers break into databases and steal login information. Some of the best known "data spills" took place at Equifax and Yahoo, but they happen fairly regularly -- there were 51 reported breaches last year, compromising 2.3 billion credentials, according to Shape. Taking over bank accounts is one way to monetize stolen login information -- in the US, community banks are attacked far more than any other industry group. According to Shape's data, that sector is attacked more than 200 million times each day.
Shape says the number of reported credential breaches was roughly stable at 51 last year, compared with 52 in 2016. The best way consumers can minimize these attacks is by changing their passwords.

    The Kohl's web site is utterly broken. Every time they have a sale, your account gets locked due to too many password attempts.

      Yeah, T-Mobile has a setup where they lock your account for 24 hours. So if you have to check something, make a change, or pay your bill you forgot about, you have to call in.

    I also have an online store for my business.

      I have done a lot of online purchasing, and starting fairly early in the game, before the new millennium, and plenty since. Some years it exceeded five figures.

      I only had one problem, where a small vendor was the victim of a php injection attack. I noticed it but it didn't "click" that I was being served a lookalike page to enter my CC details. When the transaction didn't go through, it dawned on me what was going on.

      My CC company (VISA) caught the suspicious activity on my card fairly quickly ... the thieves apparently tried three transactions, and they denied the second and third. The first (and when I talked to VISA, they said it was very common) was to pay for web hosting for three months, to a Texas based provider. The other two were in quick succession and originated at different locales, which triggered the fraud alert.

      I was issued a new card (new account #) and that was the end of it for me ... I didn't have to pay for the one charge they made. I also alerted the vendor, who was reluctant to believe me, but apparently had the smarts to hire someone who confirmed the php injection and made changes, and later sent me a message thanking me for the alert.

      But that was it. Hundreds if not thousands of transactions at every stage of eCommerce development.

    What IS true is that a perfectly logical security system, trying to determine whether a login attempt is legit, would start out with the knowledge there is a 90% chance it's not legit, before considering any other factors. Until we have evidence that it IS legit, it's probably not. That's called a prior probability. That has some interesting implications.

    Fortunately, there are some pretty straightforward metrics to identify legit and bogus attempts with high success rates when the metrics are combined correctly.

    First off, changing your passwords is a horrible strategy. Yes, you need to change them but more important is to salt them. Don't use the same password suffix on each site. Keep each password unique for each site. Second of all, retailers need to standardize on two factor authentication, like yesterday! This stops way more than 99% of all malicious login attempts.
