There\u2019s some bad news for Outlook.com users, as it's emerged that the webmail service has been compromised and some folks have had their accounts hacked, with the perpetrators even able to read emails in a limited number of cases \u2013 despite Microsoft\u2019s initial denial that email content was viewable. Details of the security breach were revealed when TechCrunch ran a report claiming that some Outlook.com accounts \u2013 and those with Hotmail email addresses (the old name for Outlook.com) or MSN.com users \u2013 had been compromised. Apparently the hackers managed to get hold of a customer support tech\u2019s login credentials, which they used to access the various consumer user accounts (paid business accounts weren\u2019t affected). Microsoft clarified that this \u201caffected a limited subset of consumer accounts\u201d and that the malicious activity began at the start of January 2019 and ran through to almost the end of March, so essentially lasted three months. However, Microsoft said the hackers could only see the user\u2019s email address, folders, and subject lines of messages (as well as addresses the user has emailed), but that they couldn\u2019t actually read the contents of an email, or view attachments (or indeed gain access to the login credentials of the account). The worry was that even limited information like email subject lines could enable malicious parties to concoct a more convincing phishing scam to aim at the user whose email they have (and they could also employ extra details like the names of friends, gleaned from the email addresses the user has contacted). Emails have been read However, it then emerged that matters were worse than Microsoft first admitted: \u00a0Motherboard spoke to a source who claimed that a \u2018large number\u2019 of accounts were affected, and what\u2019s more, in some cases, contents of emails were read by the hackers \u2013 and Microsoft subsequently confirmed the latter was true. Specifically, Microsoft admitted it had sent notifications of a security breach to some users which informed them that their email content had (potentially) been read, but that this only applied to a small amount of the affected users, around 6%. We don\u2019t know how many accounts that is, because Microsoft didn\u2019t provide an estimate of the overall number of users who were hit by this hack. Motherboard\u2019s source further claimed that the hackers actually had access to emails for around six months prior to March, but Microsoft firmly denies that. Despite the perpetrators not gaining access to account passwords, Microsoft is still recommending that if you\u2019ve been affected, you should change your password just as a precautionary measure. Of course, if you have been affected then you should have had an email informing you of this by now. It\u2019s also worth underlining that it could be a good idea to keep an eye out for potential scam or phishing emails, because as we\u2019ve already mentioned, the data gleaned from your email account \u2013 even things as simple as subject lines \u2013 could well be used to fashion a much more convincing attack to attempt to deliver malware onto your PC.
