OSINT - Return of Not Petya as Bad Rabbit Diskcoder, yes those two are the same!

The threat described involves the resurgence of ransomware variants linked to the infamous NotPetya and Bad Rabbit malware families, collectively referred to here as "Not Petya as Bad Rabbit Diskcoder." Both NotPetya and Bad Rabbit are ransomware strains that emerged around 2017 and are known for their destructive impact on infected systems. NotPetya masqueraded as ransomware but was primarily a wiper designed to cause widespread damage, while Bad Rabbit was a ransomware outbreak that spread via fake Adobe Flash installers, encrypting files and demanding ransom payments. This OSINT report highlights that these two malware strains are essentially the same or closely related, indicating a possible re-emergence or variant combining characteristics of both. The malware operates by encrypting user data and potentially disrupting workstation communications, which can severely impact business operations. The report suggests preventive measures such as maintaining robust backup and restore processes and restricting workstation communication to limit lateral movement within networks. Although the severity is marked as low in the source, the technical threat level is noted as 3, indicating a moderate concern. No known exploits in the wild are reported currently, and no specific affected versions or patches are identified, which suggests this is an intelligence observation rather than an active widespread campaign at the time of reporting.

OSINT - Bad Rabbit: Not-Petya is back with improved ransomware

Bad Rabbit is a ransomware strain that emerged in October 2017 and is considered a variant or evolution of the NotPetya ransomware attacks that occurred earlier the same year. It is designed to encrypt victims' files and demand a ransom payment for decryption keys. Unlike NotPetya, which was primarily a wiper disguised as ransomware, Bad Rabbit improved its ransomware capabilities, making it a more traditional ransomware threat. The malware typically spreads through drive-by downloads from compromised websites, masquerading as a fake Adobe Flash installer. Once executed, it encrypts files on the infected system and displays a ransom note demanding payment in Bitcoin. Bad Rabbit also attempts to propagate laterally within networks by leveraging known vulnerabilities and using credential harvesting techniques to move between workstations. However, it does not appear to exploit zero-day vulnerabilities or have widespread exploits in the wild beyond initial infection vectors. The technical details indicate a moderate threat level, with a focus on backup and restore processes and restricting workstation communication as preventive measures. The ransomware targets Windows systems and aims to disrupt business operations by denying access to critical data.

OSINT - BadRabbit Ransomware Compiled by ThaiCERT, a member of the Electronic Transactions Development Agency

BadRabbit ransomware is a malware strain first observed in October 2017, primarily targeting Windows-based systems. It is a disk-encrypting ransomware that spreads through fake Adobe Flash Player installers, tricking users into executing the malicious payload. Once executed, BadRabbit encrypts files on the infected system and demands a ransom payment in Bitcoin to decrypt the data. The ransomware uses a hardcoded list of target domains and IP addresses to determine whether to activate its payload, indicating some level of targeting or geographic filtering. Unlike some ransomware variants, BadRabbit does not appear to exploit vulnerabilities autonomously but relies on social engineering to infect victims. It also attempts to propagate laterally within networks by leveraging legitimate Windows tools such as WMIC and PsExec, which can allow it to spread to other machines if credentials are compromised or weak. The malware overwrites the Master Boot Record (MBR) to display the ransom note upon system reboot, effectively locking users out of their systems until the ransom is paid or the system is restored. Although the threat level is considered low in the provided data, BadRabbit caused significant disruption in 2017, particularly in Eastern Europe and Russia. The ransomware does not require user authentication but does require user interaction to initiate infection (i.e., running the fake Flash installer). No known exploits in the wild are reported beyond the social engineering vector. Mitigation strategies include restricting workstation communication to prevent lateral movement and maintaining robust backup and restore processes to recover encrypted data without paying ransom.

Bad Rabbit ransomware is a malware threat first identified in October 2017, classified as ransomware. It primarily spreads through drive-by downloads masquerading as Adobe Flash installer updates, targeting Windows-based systems. Once executed, Bad Rabbit encrypts files on the infected system, appending a specific extension to encrypted files and displaying a ransom note demanding payment in Bitcoin to restore access. The ransomware uses a combination of symmetric and asymmetric encryption to lock user data, making recovery without the decryption key difficult. Unlike some ransomware variants, Bad Rabbit does not appear to exploit known vulnerabilities directly but relies on social engineering and lateral movement techniques within networks, including the use of legitimate Windows tools such as Mimikatz to harvest credentials and propagate. The threat level is considered moderate, with a low severity rating assigned in the source data, likely reflecting limited impact or spread compared to other ransomware outbreaks. Mitigation strategies focus on maintaining robust backup and restore processes and restricting unnecessary communication between workstations to prevent lateral movement. No known exploits in the wild beyond the initial infection vector have been documented, and no CVSS score is available for this threat.

OSINT - Bad Rabbit ransomware

Bad Rabbit is a ransomware malware that emerged in October 2017, primarily targeting organizations through drive-by download attacks often distributed via fake Adobe Flash Player installers. It encrypts files on infected systems and demands a ransom payment in Bitcoin to restore access. Technically, Bad Rabbit propagates by dropping a malicious executable disguised as an Adobe Flash update, which when executed, installs the ransomware payload. It uses a combination of known exploits and credential harvesting techniques to spread laterally within networks, including the use of the Mimikatz tool to extract credentials and SMB protocols to move across systems. Unlike some ransomware variants, Bad Rabbit does not exploit zero-day vulnerabilities but leverages social engineering and existing network weaknesses. The malware encrypts files using strong encryption algorithms, rendering data inaccessible without the decryption key. It also attempts to disable recovery options by deleting shadow copies and system restore points. The ransom note demands payment in Bitcoin and threatens permanent data loss if the ransom is not paid within a specified timeframe. Although initially observed in Eastern Europe and Russia, the malware has the potential to affect any organization with vulnerable systems and insufficient network segmentation. The technical details indicate a moderate threat level, but the lack of known exploits in the wild and the requirement for user execution of the fake Flash installer limit its immediate risk. However, its ransomware nature and ability to disrupt business operations make it a significant concern for organizations that do not maintain robust cybersecurity hygiene.
