13 Million gamers exposed to data theft following a breach at Nexon

Hack on backup server of Maple Story

We are back with another case of data theft that involves gamers IDs being stolen. We are talking about the latest breach in the gaming industry, the Nexon Security Breach.

Around 13 million gamers have been exposed to ID theft following a breach at gaming company Nexon.
The gamers information includes names, usernames, encrypted resident registration numbers and password hashes. Nexon maintains the popular online role-playing game, Maple Story. The breach was followed by a hack on a backup server for Maple Story last week. Fortunately data of the 5 million customers using other games maintained by Nexon was not breached.

According to the company’s spokesperson the incident took place on 24 November and it had informed law enforcement agencies to investigate urgently. This breach was only limited to players of the online role-playing game Maple Story. Nexon added that Maple Story is “completely independent of the service”.

The official further added that the exposed details did not include information on financial transactions or bank account numbers and had not affected overseas subscribers of the online game.

For prevention sake, the company has requested game subscribers to change passwords although the exposed data is said to be encrypted. As of today the total subscription membership of Maple Story is about 18 million. Minors are also members of this site and have a legal consent of their parental guardians. Nexon reports that “The information concerning legal guardians of users who are under 14 years of age is not involved in the hacking as it is stored in a different server.”

This breach has chosen a bad timing for Nexon as it is in the midst of planning an IPO. The IPO is planned for Dec 6.

This is what one encryption expert had to say about the case “This is unfortunately the latest in a string of attacks against gaming sites; hackers have realised that they represent a virtual treasure trove of personal consumer data,” Pauker said. “It’s time for the gaming companies to realise that security can’t be an afterthought. Good security is just as important as good graphics.”

This is a wake-up call for Nexon and it is bolstering its security policies. As a freebee it is offering game items to gamers who agree to change their passwords.

Cyworld hit by hackers last Thursday

Headline

There was a hacking attack on Nate and Cyberworld, companies run by SK communications.

About SK

SK Communications operates the Cyworld social-networking site and the Nate portal site.

Cyworld is the biggest social-networking site with 25 million users and Nate is the third most popular Web search engine. A hotline is being set-up to help people deal with spam and from becoming a victim of phishing scams that could arise from this massive data breach.

Cyworld is very popular with the young generation in South Korea. It did try to compete with Facebook and MySpace but failed to gather users. Hence was pulled out from the competition in 2010. The site is gaining popularity in Vietnam and China, though.

The story in detail

According to a statement by SK “The company has confirmed that a leak of customers’ information has taken place due to hacking on July 26,. “The specific scale of the hacking is still being investigated, but it is estimated that some of the personal information of 35 million Nate and Cyworld members has been leaked.”

Personal data including names, addresses, phone numbers, registration details were accessed by computers in China. The IP addresses were tracked down to China and malicious software was used for hacking.

China has been in the news in the past few months for various global cyber-attacks. There’s a strong possibA recent breach of Google’s Gmail service is thought to have originated from the country. Meanwhile, China has strongly denied any involvement.

Some lessons learnt the hard way

Such incidents must be investigated and new security laws ought to be brought in. Companies with poor security could get prosecuted if they do not update their security system. Use of sensitive and personal information of users must be strictly avoided. Social security numbers are the most risky ones hence they ought to be avoided at all costs.

Personal info always attracts hackers and they go to any lengths to get it.

Post breach

Stock prices of the telecommunications giant SK Telecom has fallen down. Superiors fear that the recent data loss may leave a bad impression on its clients. Clients are very angry that there are personal info has been compromised.

Cyworld users are getting calls from lawyers convincing them to file class-action lawsuits. The crisis has left SK’s network vulnerable.

“It was extremely frustrating to see a message pop up while chatting with my friend that read `You’ve been hacked,’’’ said Nate user Kim Jeong-eun, who plans to sign up for the class-action lawsuit.

The worst that could happen is information-sensitive Koreans might move from SK Communications to another social media and Internet service.

While delivering his talk in South Korea, Dr. Robert Levine would have got little idea that his laptop would be stolen. A couple of months ago, Dr. Levin, a nuerologist specializing in ears, was conducting a lecture and he later discovered that his laptop containing vital information for over 22 years was stolen from the premises.

According to the analysis done by Mass. Eye and Ear it was determined that Dr. Levine’s laptop contained critical demographic and health information of around 3,526 patients all of whom were treated by Dr. Levine at Mass. Eye and Ear during February 3, 1988 and February 16, 2010. Additionally, the laptop also included info of a small number of participants in research conducted by Dr. Levine at Mass. Eye and Ear who were not also Dr. Levine’s patients, as follows:

  • 67 participants in somatic tinnitus modulation research
  • One participant in pulsatile tinnitus research.

As per the new rules defined by the legislation, the responsible authority has to inform the affected individuals. Following the regulations, Mass Eye and Ear is informing the patients and research participants about the loss of information.

Name, Address, Telephone numbers, E-mail, Date of birth and age, Sex, Medical record numbers, Dates of service, Medical information, including diagnoses, symptoms, test results, and prescriptions, Name and contact information for patient pharmacies and Research participant status.

The light at the end of this news is that critical information like Social Security numbers, financial account numbers, and credit or debit card numbers were not present on the laptop. Due credit needs to be given to the hospital for taking all the necessary action from their side. Letters have been dispatched to the affected individuals and also a notice has been posted on the website to inform all the individuals whose contact data is out of date.

Individuals who fit into one of the categories above, and who do not receive a letter directly from Mass. Eye and Ear, may contact the Mass. Eye and Ear Breach Response Center at 877-313-1395 to determine if they are affected.
