The massive system update has been reported about on the official blog of the world leading payment processor Liberty Reserve. Basically th most serious thing about the update is securing more than a dozen of Liberty Reserve accounts via API protocol. The accounts still were secured in a very uncommon way. All funds from those accounts have been transferred out as reported until the situation is resolved. The funds from the accounts remain in the system and it's been declared that once the issue is resolved, they will be moved back to the accounts involved. Liberty Reserve apologizes for not warning the users beforehand, assuming that this would have been counterproductive and would have caused delays with further resolutions. Hence it was done it that way. Please see the explanation for the measures taken from the official Liberty Reserve blog quoted:
"Running a system, as complex, as Liberty Reserve requires us to stay on cutting edge of latest technologies and solutions available while continuously trying to improve and make our system easier and more user friendly. This "balancing" act sometimes has its price tag of having to inconvenience our users once in a while, but rewards us with more sound system integrity and security. As always, your funds are safe with Liberty Reserve and you can count on us being there for you, even when it does not visibly appear to be so."
Once again Liberty Reserve warns every user against using any 3rd party e-wallet software that has not been produced by Liberty Reserve team. At the same time the authorities remind not to click on any links within the suspicious e-mails as if sent on behalf of Liberty Reserve. The business owners are highly recommended to audit the programmers and developers, limiting or restricting access to the servers for the system admins, for as it turned out multiple times "...corrupt system administrators, programmers,disgruntled former employees, etc., appeared to be number one reason for unauthorized account access."
