Choosing the Right Multi-Factor Authentication Tools for Your Credit Union

 

By Robert McGarvey

 

The multi-factor authentication tools your credit union implements may win you members – but the wrong ones just may cost you members while driving away mobile and online banking users.  It’s also very, very possible that soon authentication will become a key battleground in member retention.

That’s how important multi-factor authentication (aka MFA) has become in today’s financial services.

Passwords plainly are broken.  Between epidemic breaches – Equifax for instance – and rampant user laziness (such as using the same password at multiple sites), a password alone is not adequate protection for most accounts involving money.

Enter multi-factor authentication which, often, rides on top of a password. The password may be adequate for low value tasks but when bigger money is on the line, it’s time to bring out multi-factor to provide beefed up protection.

FFIEC provides interesting insights into the role of multi-factor authentication in financial institutions:  “A common example of two-factor authentication is found in most ATM transactions where the customer is required to provide something the user possesses (i.e., the card) and something the user knows (i.e., the PIN). Single factor authentication alone may not be adequate for sensitive communications, high dollar value transactions, or privileged user access (i.e., network administrators). Multi-factor techniques may be necessary in those cases.”

Plainly we have entered an age where consumer expectation about the availability of multi- factor has vaulted ever higher. Personally I use multi-factor on Amazon.  I also have it setup on Google.  So of course I expect it, and use it, at Affinity Federal Credit Union.

Understand this however: there is ample evidence that many consumers rebel against MFA that is deemed too cumbersome, too much of a hassle.  It’s something of a double-bind. They want to feel protected by their financial institution but they also don’t want to feel hassled.

Yet good, trustworthy MFA increasingly looks to be critical in fueling credit union account growth, especially usage of lower cost digital channels (online and mobile).  But lots of Americans shy away from online and mobile banking because of fears of data insecurity in the digital channels. Multi-factor can be the cure.

Mark this as a key 2017 challenge: offering members MFA they will use, gladly, and that leaves them feeling their financial data are safe.  

That is easier to say than to deliver.

Increasingly, multi-factor offers a choice among something the user knows (a PIN perhaps, or a favorite teacher in grammar school), something the user has (a cellphone perhaps or an ATM card), and something the user is, that is, a biometric solution and gaining traction there are fingerprints of course – think Apple Pay and Touch ID – but also retinal scans, which have gained popularity at money center banks (particularly Wells Fargo).  

More attention nowadays is going into biometrics because, thanks to Apple, more of us are comfortable using a biometric tool to perform a financial task and, to most of us, biometric factors seem beyond the reach of most criminals.  

What should you offer? Best advice is to offer members a choice of multiple tools and let the member decide.  Some people still think retinal scans are creepy, others have seen it at high security office buildings and like them.  There is no disputing member tastes.

Put out a menu of maybe five or six tools and let members decide what they like.

Key is that what they use cannot seem intrusive or a hassle – to them. They get the only vote that counts.

Also good are protective tools the consumer may be unaware of, such as looking for trusted, known devices and trusted, known locations. When a member who lives in Phoenix, AZ is signing into a sharedraft account at a local credit union, that institution can breath easier when it recognizes the computer and the member location – and the member has no need to know these checks have been made.

Key also is providing flexibility. A member may like using voice as a biometric when signing into the credit union in the early a.m. from home – but probably would think it weird when signing in from a busy Starbucks at noon.

Give members choices and they will use them.

Also stay on top of news developments and, definitely, there is news in the multi-factor space.

A sore spot to watch is SMS which, frequently, figures into multi-factor authentication, where a PIN is sent to a registered cellphone number. The user then inputs that PIN at a banking site.  But – increasingly – there is evidence that smart crooks have figured out how to simply steal cellphone numbers and thereby hijack the SMS traffic.  Worries are big enough that the National Institute of Standards and Technology (NIST) has begun to back away from SMS, as awareness grows that the safety of the cellphone channel is in doubt.

Right now, cellphones and SMS remain integral in the multi factor techniques deployed by most financial institutions but smart money is betting that will change unless cellphone carriers impose better processes to safeguard number transfers.

Note: this author recently transferred a number from one carrier to another and from one device to another and, frankly, the process was frictionless – which has to raise security worries.  But – again – it would be easy enough to erect some hurdles in the process and that might restore confidence in cellphone SMS.

The message there: stay on top of developments. Crooks are energetic in hunting for new weaknesses to exploit. Credit unions have to be as energetic in their self-defense tactics.

Want more ideas about what tools to use? Good advice is to look at leaders in the field and recent ratings from Javelin Strategy & Research heap particular praises on USAA, Wells Fargo, Bank of America, Bank of the West, and Fifth Third when it comes to preventing fraud involving member accounts. Only the very largest institutions were compared so don’t look for credit unions.  

Are your tools in the same class? They should be. That’s how to keep members.

Meantime, CU-2.0’s Kirk Drake pointed to emerging tools that credit unions need to know about.  Said Drake: “Using things like DAON, AnchorID, DUO, Averon, etc. really allow you to elevate the member experience while increasing security.” 

The point: credit unions have a growing number of authentication options. New ones are emerging. Learn about them, use them.  This just may become a key battleground in member retention in the years ahead. Falling behind is not an option.

 

Russian Hackers May Be Targeting Your Hotel and Your Data

 

By Robert McGarvey

The statement from security firm FireEye has to put a chill in you: “FireEye has moderate confidence that a campaign targeting the hospitality sector is attributed to Russian actor APT28. We believe this activity, which dates back to at least July 2017, was intended to target travelers to hotels throughout Europe and the Middle East.”

There’s no doubt that there has been a hacking campaign. The “moderate confidence” applies only to attribution to the Russian hackers.

FireEye continued: “FireEye has uncovered a malicious document sent in spear phishing emails to multiple companies in the hospitality industry, including hotels in at least seven European countries and one Middle Eastern country in early July. Successful execution of the macro within the malicious document results in the installation of APT28’s signature GAMEFISH malware.”

Then the news turned awful: “Once inside the network of a hospitality company, APT28 sought out machines that controlled both guest and internal Wi-Fi networks.”

WIRED Magazine fanned the anxieties: “APPROPRIATELY PARANOID TRAVELERS have always been wary of hotel Wi-Fi. Now they have a fresh justification of their worst wireless networking fears: A Russian espionage campaign has used those Wi-Fi networks to spy on high-value hotel guests, and recently started using a leaked NSA hacking tool to upgrade their attacks.”

This is not fretting about kiddie hackers. According to Reuters, “Several governments and security research firms have linked APT 28 to the GRU, Russia’s military intelligence directorate. ”

That’s significant. That means we all need to be just a bit worried. This is a slick, professional attack. Nobody denies that, even though some aren’t convinced Russians are the actors.

The attacks have been slick. That’s the issue.

Remember, the biggest worries involve hotels outside the US.

In the US, many of know to use hotel WiFi sparingly if at all.  Domestic hotels have been under assault by hackers for some years and good advice is just don’t use the WiFi for anything meaningful that involves a password. That means corporate email, banking, even frequent flier accounts.  

That’s because the odds are high that criminals are sniffing the data stream over any public WiFi network and are seeking to pull out usernames and passwords.

But here’s the kicker: ignoring public WiFi domestically is easy.  I just create a personal hotspot, either on my TMobile iPhone or Google Fi Pixel, and I am good to go – often at speeds that rival hotel WiFi anyway.  That communication over the cellular network is significantly more secure than a public WiFi network so my advice is use it.

Abroad our choices are more complicated.  That’s because data abroad either is very slow or it comes at a price or both.

Set up a hotspot for data in Paris and very likely you will pay.

But now that is emerging as the better solution.

AT&T offers a calculator to help guide how much data to buy.  

Personally I will keep it simple by using T-Mobile, which offers free data – at slower speeds – in some 140 countries.  

Google Project Fi – in 135 countries – costs $10 per gigabyte for whatever speed Google can deliver.  

You want to know how you will create your own hotspot before your next foreign trip.

That’s because you – not the hotel – apparently are the target of the hackers.

FireEye elaborated: “Cyber espionage activity against the hospitality industry is typically focused on collecting information on or from hotel guests of interest rather than on the hotel industry itself, though actors may also collect information on the hotel as a means of facilitating operations. Business and government personnel who are traveling, especially in a foreign country, often rely on systems to conduct business other than those at their home office, and may be unfamiliar with threats posed while abroad.”

What kinds of hotel are the Russian hackers targeting? Here’s Fire Eye’s info: “FireEye says that the hacked networks were those of moderately high-end hotels, the kind that attract presumably valuable targets. ‘These were not super expensive places, but also not the Holiday Inn,’ FireEye’s [Ben] Read says. “They’re the type of hotel a distinguished visitor would stay in when they’re on corporate travel or diplomatic business.”

Sound like the kind of place you’d stay in?

Definitely it is my profile.

Note: FireEye is adamant that using a VPN may not provide complete protection against the tools the Russian are deploying.  Definitely, use a VPN when traveling abroad – just don’t be certain it is protecting against sophisticated intercepts.

So create your own hotspot.  Right now, that looks to be safe, abroad just as it is domestically.
