The hacks keep coming. It's been a year since we rounded up theusual suspects and looked at just how vulnerable our private datais, so we decided to take another look.

We confine our lists to financial data, but we have to note thebreach of ashleymadison.com, a website designed to allow spouses tocarry on extramarital affairs. The data stolen from the siteincluded that of a decidedly more personal nature, and the angstthe theft caused – not to mention the media storm – was riveting towatch.

A blog on the site govtech.com noted that, indeed, thehacks in 2015 were of a more personal nature than those in thepast. Instead of just stealing credit card numbers, bank accountdata and Social Security numbers, thieves got their hands onfingerprints, hospital records and other information not meant tobe shared with strangers.

The take-home lesson is that cyber data is unsafe and more needsto be done to ensure its security. Whether 2016 is the yearcompanies, governments and people get wise to that is unclear.

Check out 6 Big Hack Attacks Targeting Financial Data, ranked inreverse order by number of people affected.

6-Landry'sRestaurants

Going out to eat is something most of us do without a secondthought; the only safety concerns crossing our minds are whetherrestaurants are ensuring the food is cooked properly and the placeis clean.

A 2015 hack attack on a national restaurant holding companymight change that. The Landry chain, which is based in Houston andincludes more than 500 restaurants, reported that credit card datawas stolen from some of its locations around the U.S. The breach,which occurred between May and December, was discovered whenunauthorized charges were made on the credit and debit cards ofcustomers of restaurants that include McCormick & Schmick's,Morton's, Rainforest Café and others.

The total scope of the hack has not been revealed. Landry's saysit took steps to enhance its data security.

5. UCLA HospitalSystem

Add hospitals to the list of not-so-safe computer systems. UCLAHealth was hacked, and the records of 4.5 million workers andpatients were accessed. The data taken included medical info,Social Security and Medicare numbers and home addresses. As withmany hacks, the breach went unnoticed at first and then wasn't madepublic for weeks after it was first identified. In August, a monthafter the hack became known publicly, a class action lawsuit wasfiled, according to the Los Angeles Times. The Times noted thatsome cybersecurity experts said UCLA was negligent for notencrypting the data.

4. Premera BlueCross

Health insurers have lots of personal information and withrecords being kept online, the vulnerability is clear. The hackerswho hit Premera in March 2015 found a supermarket of data ready forthe taking. And take they did, according to the insurer. The claimsrecords, bank account numbers and Social Security numbers for asmany as 11 million customers, about half in Washington state, werestolen.

The data went back as far as 2002, and security experts quotedat the time of the breach said the attack started with a boguswebsite spoofing Premera's site. That's similar to the techniqueused to hack Anthem's database the previous year. The idea, theexperts said, is to get customers to sign in to the bogus site,allowing the hackers to collect online names and passwords.

3. T-Mobile/Experian

A unit of Experian, the credit tracking company, holdingT-Mobile customer data was hacked, leaving the data of 15 millionpeople at risk of misuse. The information taken was held on serversowned by Experian. A class action lawsuit filed in the theft notedthe irony of a company that promises to guard data being breached.The lawsuit stated that Experian was hacked in 2012 and the data ofmore than 200 million customers was stolen. Information fromapplications submitted to T-Mobile from 2013 to 2015 includedSocial Security numbers and names and addresses. The hack left openthe possibility of identity theft.

2. Office of PersonnelManagement

In what might be the most horrifying data breach of the lastyear, the U.S. government's Office of Personnel Management washacked and information on 21 million current and former employees,as well many who had applied for positions, was stolen.

Not only did the hack illustrate the fact that no database issafe, the hackers made off with the fingerprints of more than 5million people.

The government offered free cyber monitoring services to thoseaffected while the search for the thieves was on. The hack waswidely attributed to the Chinese government. A recent article onfederaltimes.com interviewed officials who noted that under the“norms” of government espionage, the data theft might not have beenillegal. Small comfort for those whose information was lifted.

1. Financial Hacking RingBusted

In a spectacular announcement last fall, authorities said theyhad arrested the mastermind behind a ring of cyber thieves that hadstolen the financial records of more than 100 million customer of12 financial institutions, including JPMorgan and Fidelity.
