Ubisoft is the latest computer games company to be hacked, with usernames, email addresses and encrypted passwords compromised
Although French game publisher Ubisoft claims no payment information was compromised, another breach at a gaming company has raised concerns about security of all online services.

Ubisoft has not revealed exactly how many customers were affected in the user account database breach or how the compromise took place, saying only that the attack “did not originate via any Uplay services” in a blog post.
Ubisoft said in a statement: "We recently found that one of our websites was exploited to gain unauthorised access to some of our online systems.
“We instantly took steps to close off this access, investigate the incident and begin restoring the integrity of any compromised systems."
The gaming company has asked all its customers to reset the passwords for their Ubisoft account and for any other website or service where they use the same or a similar password.

The breach at Ubisoft is the latest attack on gaming companies, the most notable of which was the breach of the Sony PlayStation Network Platform in April 2011 that compromised the personal information of millions of customers.
Within four months of the breach, Sony appointed a chief information security officer (CISO) for the first time.
Sony's initial estimate put the damage at £104m, but pundits said the biggest loss would be in reputational damage as lack of confidence hit Sony's share price.
In January 2013, the UK privacy watchdog issued a monetary penalty of £250,000 against Sony Computer Entertainment Europe in connection with the breach.
An investigation by the Information Commissioner’s Office found the attack could have been prevented if software had been up to date and that technical developments meant passwords were not secure.
