Microsoft has revealed this week that documents “associated with law enforcement inquiries” were stolen during recent attacks on employee email accounts. The software giant has been the subject of a recent campaign by the Syrian Electronic Army to compromise Microsoft email and social media accounts. While Microsoft previously confirmed the Syrian Electronic Army had been able to breach a “small number” of employee email accounts, a further warning was issued yesterday.

Documents linked with law enforcement inquiries appear to have been stolen in recent phishing attacks on certain employee email accounts, Microsoft said. The technology giant said earlier this month that a small number of Microsoft employee social media and email accounts had been impacted in a phishing attack. The accounts were reset and no customer information was compromised, Microsoft said. On Friday, Adrienne Hall, general manager in Microsoft’s Trustworthy Computing Group, said in a blog post that it appeared that documents associated with law enforcement inquiries were stolen. “If we find that customer information related to those requests has been compromised, we will take appropriate action,” Hall said.
