A widespread ransomware outbreak is affecting numerous organizations in Europe, particularly in the Ukraine. New reports indicate that the ransomware has spread to North America. No eSentire customers are known to have been impacted by this attack. The ransomware appears to leverage multiple propagation mechanisms, including the ETERNALBLUE exploit that was previously used by the WannaCry ransomware worm.
What you should do about it:
There have been reports of malicious Word documents using the CVE-2017-0199 vulnerability being used as the initial infection vector for this ransomware attack. We have not confirmed these reports as yet.
Currently, known hashes of files associated with this threat are as follows:
While the ETERNALBLUE SMB exploit appears to be the primary propagation mechanism, we have observed attempts by the malware to connect to network shares via the WebDAV protocol. In addition, the malware sample we’ve analyzed also contains the PsExec utility from Sysinternals – this appears to be another means of propagation from the initial victim to other machines on the internal network.
Deployment of the MS17-010 patches is extremely important. The Microsoft SMB vulnerability is the primary means of spread. If your network is impacted by this or any other ransomware attack, we do not recommend ransom payment, as there is no guarantee that the affected data will be recovered.
