According to Avast malware researcher Jakub Kroustek, most of the detections are coming from Russia, Ukraine, India and Taiwan. wannacry attack distribution Kaspersky Lab forum users report that the WannaCry ransomware managed to infiltrate the internal computer system of the Ministry of Internal Affairs of Russia and Investigative Committee of Russia. “It first appeared in February 2017, but now it’s updated and looks different than previous versions”, said one of the Kaspersky Lab forum users. Spain’s Computer Emergency Response Team CCN-CERT also posted an alert on their site about a widescale ransomware attack affecting a few Spanish organizations. The National Health Service (NHS) in the U.K. also issued an alert and confirmed infections at 16 medical institutions. The WannaCry attacks are initiated using an SMBv2 remote code execution in Microsoft Windows OS. The EternalBlue exploit has been made publically available through the Shadowbrokers dump on April 14th, 2017 and patched by Microsoft on March 14. However, many companies and public organizations have not yet installed the patch to their systems.

  • Emails and email databases (.eml, .msg, .ost, .pst, .edb).
  • Database files (.sql, .accdb, .mdb, .dbf, .odb, .myd).
  • Developers’ sourcecode and project files (.php, .java, .cpp, .pas, .asm).
  • Encryption keys and certificates (.key, .pfx, .pem, .p12, .csr, .gpg, .aes).
  • Graphic designers, artists and photographers files (.vsd, .odg, .raw, .nef, .svg, .psd).
  • Virtual machine files (.vmx, .vmdk, .vdi).

How to Prevent WannaCry infection?
1. Make sure that all hosts have enabled endpoint anti-malware solutions. 2. Install the official Windows patch (MS17-010), which closes the SMB Server vulnerability used in this ransomware attack. 3. Scan all systems. After detecting the malware attack as MEM:Trojan.Win64.EquationDrug.gen, reboot the system. Make sure MS17-010 patches are installed. 4. Backup all important data to an external hard drive or cloud storage service.

Zombie ZERO can defend the second WannaCry against new and variant Ransomware without signatures. Existing antiviruses can not prevent the upcoming WannaCry, a new malware.
