Urgent Announcement

McAfee is receiving multiple reports of modified Petya ransomware variants. McAfee Labs is receiving various samples which are in analysis, and can confirm that McAfee Global Threat Intelligence (GTI) is protecting against current known samples at the low setting.

  • Extensions currently known as being affected are:  .3ds, .7z, .accdb, .ai, .asp, .aspx, .avhd, .back, .bak, .c, .cfg, .conf, .cpp, .cs, .ctl, .dbf, .disk, .djvu, .doc, .docx, .dwg, .eml, .fdb, .gz, .h, .hdd, .kdbx, .mail, .mdb, .msg, .nrg, .ora, .ost, .ova, .ovf, .pdf, .php, .pmf, .ppt, .pptx, .pst, .pvi, .py, .pyc, .rar, .rtf, .sln, .sql, .tar, .vbox, .vbs, .vcb, .vdi, .vfd, .vmc, .vmdk, .vmsd, .vmx, .vsdx, .vsv, .work, .xls, .xlsx, .xvd, .zip
  • We have confirmed with the samples that SMB is being used as a propogation method, and are aware of reports that RDP may also be used but have yet to confirm this.
  • After encryption, impacted systems may show a ransom screen and suggest a system reboot after which the system will not be accessible.

McAfee has released an Extra.DAT to include coverage for this threat — it is attached to KB89540.
