NotPetya
NotPetya (canonical naming with industry alternatives ExPetr / Petya.A / PetrWrap / Netya / Nyetya / EternalPetya per Kaspersky + Cisco Talos + ESET + multiple convergent analyses.
cluster-defining destructive cyberweapon disguised as ransomware) is Sandworm Team's (Russian GRU Unit 74455, also Mandiant APT44 / Microsoft Seashell Blizzard, curated separately as sandworm_team parent operator) most economically destructive cyberweapon, the most economically destructive cyberattack in history per White House $10B+ damage assessment per Tom Bossert former US Homeland Security advisor per Wired report.
deployed June 27, 2017 on eve of Ukrainian Constitution Day (June 28) via cluster-defining M.E.Doc Ukrainian tax/ accounting software supply chain compromise (M.E.Doc / Medok mandatory software used by ~80% of Ukrainian businesses developed by small family-run Linkos Group led by Olesya Linnik.
Sandworm pre-compromised M.E.Doc update servers months prior via Linkos's 4+ years of neglected server security per Ukrainian cybercrime unit July 2017 Intellect Services seizure analysis showing no security patches + evidence of Russian presence + several compromised employee accounts.
May 18, 2017 XData ransomware test run established M.E.Doc update channel viability)
standalone malware platform cluster paralleling blackenergy + industroyer + olympic_destroyer in Sandworm-platform-family cell; rapid 4-vector propagation tradecraft integrating EternalBlue (CVE-2017-0144 NSA-developed SMBv1 RCE released by Shadow Brokers April 14, 2017 + patched by Microsoft MS17-010/KB4013389 March 14, 2017) + EternalRomance (CVE-2017-0145 paired NSA SMBv1 RCE) + Mimikatz (LSASS credential dumping for lateral movement) + WMI (Windows Management Instrumentation lateral execution) + PSExec (sysadmin utility lateral execution)
destructive payload encrypts Master Boot Record + file system table + displays Bitcoin ransom demand but no functional decryption mechanism existed , pure destructive cyberweapon disguised as ransomware; impact metrics ~80% infections in Ukraine + Germany 9% second-most affected + 65+ countries impacted (Kaspersky-recorded infections France + Germany + Italy + Poland + UK + US with majority Russia + Ukraine), 80+ Ukrainian initial targets including National Bank of Ukraine, Maersk Line $200-300M lost revenues (canonical recovery narrative includes powerless server in Ghana accidentally saving company), FedEx TNT Express European subsidiary $400M business impact, Merck pharmaceutical substantial losses, Mondelez + Reckitt Benckiser + several French companies + Pennsylvania hospital, Ukrainian ministries + banks + metro systems affected, Chernobyl Nuclear Power Plant radiation monitoring system offline, boomerang effect infected Russian state oil company Rosneft demonstrating destructive cyberweapon collateral scope.
