Multiple Petya Ransomware Infections Reported

Original release date: June 27, 2017

US-CERT has received multiple reports of Petya ransomware infections
occurring in networks in many countries around the world. Ransomware
<https://www.us-cert.gov/security-publications/Ransomware> is a type of
malicious software that infects a computer and restricts users' access to
the infected machine until a ransom is paid to unlock it. Individuals and
organizations are discouraged from paying the ransom, as this does not
guarantee that access will be restored. Using unpatched and unsupported
software may increase the risk of proliferation of cybersecurity threats,
such as ransomware.

Petya ransomware encrypts the master boot records of infected Windows
computers, making affected machines unusable. Open-source reports indicate
that the ransomware exploits vulnerabilities in Server Message Block (SMB).
US-CERT encourages users and administrators to review the US-CERT article
on the Microsoft SMBv1 Vulnerability
and the Microsoft Security Bulletin MS17-010
<https://technet.microsoft.com/library/security/MS17-010>. For general
advice on how to best protect against ransomware infections, review US-CERT
Alert TA16-091A <https://www.us-cert.gov/ncas/alerts/TA16-091A>. Please
report any ransomware incidents to the Internet Crime Complaint Center (IC3)
