	"plain_text": "ExPetr/Petya/NotPetya is a Wiper, Not Ransomware\r\nBy Anton Ivanov\r\nPublished: 2017-06-28 · Archived: 2026-04-06 00:26:32 UTC\r\nIncidents\r\nIncidents\r\n28 Jun 2017\r\n 1 minute read\r\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 1 of 7\n\nAfter an analysis of the encryption routine of the malware used in the Petya/ExPetr attacks, we have thought that\r\nthe threat actor cannot decrypt victims’ disk, even if a payment was made.\r\nThis supports the theory that this malware campaign was not designed as a ransomware attack for financial gain.\r\nInstead, it appears it was designed as a wiper pretending to be ransomware.\r\nBelow the technical details are presented. First, in order to decrypt victim’s disk the attackers need the installation\r\nID:\r\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 2 of 7\n\nIn previous versions of “similar” ransomware like Petya/Mischa/GoldenEye, this installation ID contains crucial\r\ninformation for the key recovery. After sending this information to the attacker they can extract the decryption key\r\nusing their private key.\r\nHere’s how this installation ID is generated in the ExPetr ransomware:\r\nThis installation ID in our test case is built using the CryptGenRandom function, which is basically generating\r\nrandom data.\r\nThe following buffer contains the randomly generated data in an encoded “BASE58” format:\r\nIf we compare this randomly generated data and the final installation ID shown in the first screen, they are the\r\nsame. In a normal setup, this string should contain encrypted information that will be used to restore the\r\ndecryption key. For ExPetr, the ID shown in the ransom screen is just plain random data.\r\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 3 of 7\n\nThat means that the attacker cannot extract any decryption information from such a randomly generated string\r\ndisplayed on the victim, and as a result, the victims will not be able to decrypt any of the encrypted disks using the\r\ninstallation ID.\r\nWhat does it mean? Well, first of all, this is the worst-case news for the victims – even if they pay the ransom they\r\nwill not get their data back. Secondly, this reinforces the theory that the main goal of the ExPetr attack was not\r\nfinancially motivated, but destructive.\r\nOur friend Matt Suiche from Comae Technologies independently came to the same conclusion.\r\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 4 of 7\n\nLatest Webinars\r\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 5 of 7\n\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 6 of 7\n\nReports\r\nKaspersky researchers analyze updated CoolClient backdoor and new tools and scripts used in HoneyMyte (aka\r\nMustang Panda or Bronze President) APT campaigns, including three variants of a browser data stealer.\r\nKaspersky discloses a 2025 HoneyMyte (aka Mustang Panda or Bronze President) APT campaign, which uses a\r\nkernel-mode rootkit to deliver and protect a ToneShell backdoor.\r\nKaspersky GReAT experts analyze the Evasive Panda APT’s infection chain, including shellcode encrypted with\r\nDPAPI and RC5, as well as the MgBot implant.\r\nKaspersky expert describes new malicious tools employed by the Cloud Atlas APT, including implants of their\r\nsignature backdoors VBShower, VBCloud, PowerShower, and CloudAtlas.\r\nSource: https://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nhttps://securelist.com/expetrpetyanotpetya-is-a-wiper-not-ransomware/78902/\r\nPage 7 of 7",
