According to the reports, the IMF sent a message to employees warning them of potential spear-phishing attacks that might occur following the compromise of the data. Another memo reportedly states that the IMF is cutting off its connection to the World Bank as a precautionary measure.
Experts suggested that the warnings about spear phishing could indicate that an infection might have been spread via email. Others suggested that the warnings might indicate that a database containing employee email addresses might have been among the compromised systems.
Bloomberg quoted an unnamed source who stated that a "large quantity" of data had been compromised, possibly over a period of weeks. IMF spokespeople are not commenting.
