Dating sites can make juicy targets for hackers . Muslim focused site PureMatrimony.com says it has informed its users of an apparent d ata breach, Attack.Databreach and asked them to reset their passwords . `` Looking for a practising single Muslim ? Look no further . We have over 100,000 members , '' PureMatrimony.com reads . Apart from a focus on a specific demographic , Pure Matrimony works very much like any other dating site , and has a free sign up process . Motherboard obtained a list of some 120,000 hashes—a string of characters that can represent a user 's password—that w ere dumped Attack.Databreach on a password cracking forum , and that appear to relate to Pure Matrimony . They were hashed with the weak MD5 algorithm , meaning that hackers could likely o btain Attack.Databreach many real passwords from them . Indeed , several users on the forum had seemingly successfully cracked a number of the hashes . Many of the hashes , when translated to plaintext versions , read `` purematrimony , '' or `` purematrimony1 , '' for example . The posted data did not include any other account information , such as email addresses or usernames . `` Customers have already been notified of the incident via email , '' a Pure Matrimony representative told Motherboard in an email . `` Customers have been notified to change their passwords on their profile accounts as well as any other places online where they may have used the same password . '' The company claimed that Pure Matrimony 's site had not been hacked , but believes a vulnerability in a third party service provider may be to blame . Motherboard could not independently verify this claim . `` Our team have taken advice from two separate independent security consultants to ensure that we are doing everything possible to secure our data and protect our members . Aside from the additional security measures and moving our website to a new server , we have informed members and also logged this with the ICO [ the UK 's Information Commissioner 's Office , which upholds data protection in the country ] , '' the representative added . Last year , Motherboard reported on a d ata breach Attack.Databreach of another Muslim dating site , Muslim Match . In that case , hackers managed to g rab Attack.Databreach the full content of messages between members . The lesson : As Pure Matrimony advises , users should change their passwords , and especially on sites where they used the same login details . But it 's not clear how successful a hack might be at breaking into other accounts , since the the data did not include usernames or email addresses .
