A new wave of attacks on Microsoft Exchange has government cybersecurity officials on edge, fearing a recurrence of the havoc caused earlier this year by hackers.
Cybercriminals are aggressively targeting months-old loopholes in Microsoft’s ProxyShell, according to the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency.

Cybersecurity Director of the National Security Agency, Rob Joyce, also recommended organizations to patch against the flaws.
