Barts Health Trust , which runs The Royal London , St Bartholomew 's , Whipps Cross , Mile End and Newham hospitals , is investigating the breach . The trust said it could now rule out ransomware , in which email recipients are tricked Attack.Phishing into opening attachments which contain viruses , as the cause . It has not confirmed how much of its system was affected but said there was no sign that patient data was accessed Attack.Databreach . In a statement said : `` We are urgently investigating this matter and have taken a number of drives offline as a precautionary measure . `` We have tried and tested contingency plans in place and are making every effort to ensure that patient care will not be affected . '' The incident Attack.Ransom follows a similar attack Attack.Ransom on the Northern Lincolnshire and Goole Foundation Trust in October , when malware was used to encrypt files on the trust 's system and demand a ransom Attack.Ransom in order to access them again . The trust did not pay out Attack.Ransom , but was forced to cancel patient appointments while its systems were shut down to remove the virus

The toys -- which can receive and send voice messages from children and parents -- have been involved in a data breach Attack.Databreach dealing with more than 800,000 user accounts . The breach Attack.Databreach , which grabbed headlines on Monday , is drawing concerns from security researchers because it may have given hackers access Attack.Databreach to voice recordings from the toy 's customers . But the company behind the products , Spiral Toys , is denying that any customers were hacked Attack.Databreach . Absolutely not , '' said Mark Meyers , CEO of the company . Security researcher Troy Hunt , who tracks data breaches Attack.Databreach , brought the incident Attack.Databreach to light on Monday . Hackers appear to have accessed Attack.Databreach an exposed CloudPets ' database , which contained email addresses and hashed passwords , and they even sought to ransom Attack.Ransom the information back in January , he said in a blog post . The incident Attack.Databreach underscores the danger with connected devices , including toys , and how data passing through them can be exposed Attack.Databreach , he added . In the case of CloudPets , the brand allegedly made the mistake of storing the customer information in a publicly exposed Attack.Databreach online MongoDB database that required no authentication to access . That allowed anyone , including hackers , to view and steal Attack.Databreach the data . On the plus side , the passwords exposed Attack.Databreach in the breach Attack.Databreach are hashed with the bcrypt algorithm , making them difficult to crack . Unfortunately , CloudPets placed no requirement on password strength , meaning that even a single character such as letter `` a '' was acceptable , according to Hunt , who was given a copy of the stolen data last week . As a result , Hunt was able to decipher a large number of the passwords , by simply checking them against common terms such as qwerty , 123456 , and cloudpets . `` Anyone with the data could crack a large number of passwords , log on to accounts and pull down the voice recordings , '' Hunt said in his blog post . Security researcher Victor Gevers from the GDI Foundation said he also discovered the exposed database from CloudPets and tried to contact the toy maker in late December . However , both Gevers and Hunt said the company never responded to their repeated warnings . On Monday , California-based Spiral Toys , which operates the CloudPets brand , claimed the company never received the warnings . `` The headlines that say 2 million messages were leaked Attack.Databreach on the internet are completely false , '' Meyers said . His company only became aware of the issue after a reporter from Vice Media contacted them last week . `` We looked at it and thought it was a very minimal issue , '' he said . A malicious actor would only be able to access Attack.Databreach a customer 's voice recording if they managed to guess the password , he said . `` We have to find a balance , '' Meyers said , when he addressed the toy maker 's lack of password strength requirements . He also said that Spiral Toys had outsourced its server management to a third-party vendor . In January , the company implemented changes MongoDB requested to increase the server 's security . Spiral Toys hasn ’ t been the only company targeted . In recent months , several hacking groups have been attacking Attack.Databreach thousands of publicly exposed MongoDB databases . They ’ ve done so by erasing the data , and then saying they can restore it , but only if victims pay a ransom fee Attack.Ransom . In the CloudPets incident , different hackers appear to have deleted the original databases , but left Attack.Ransom ransom notes on the exposed systems , Hunt said . Although the CloudPets ’ databases are no longer publicly accessible , it appears that the toy maker hasn ’ t notified customers about the breach Attack.Databreach , Hunt said . The danger is that hackers might be using the stolen information to break into customer accounts registered with the toys . But Meyers said the company found no evidence that any hackers broke into customer accounts . To protect its users , the company is planning on a password reset for all users . `` Maybe our solution is to put more complex passwords , '' he said .
