“Qilin” may be referring to a mythical Chinese creature that is said to appear when a sovereign with a heart of benevolence is born.įortinet customers are already protected from these malware variants through FortiGuard’s Web Filtering, AntiVirus, FortiMail, FortiClient, and FortiEDR services, as follows: SnatchįortiGuard Labs detects the latest Snatch ransomware variant described in this blog with the following AV signature: The name of its ransom note starts with the file extension it adds to the affected files, followed by “-RECOVER-README.txt”.Ī threat actor called "Qilin" is said to be responsible for Agenda ransomware operations. For example, if a ransomware variant uses ".fortinet" as a file extension, "blog.docx" will be changed to "blog.fortinet". The file extension appended to encrypted files varies from variant to variant. ![]() This technique has been observed in other infamous ransomware families, such as REvil, BlackMatter, and AvosLocker. In an attempt to circumvent detection by AV solutions, the ransomware encrypts files in safe mode. Agenda ransomware is deployed to the compromised machines once the attacker gains access to a critical mass of devices on the network. The attacker then propagates through the victim’s network to compromise additional machines. The reported infection vector of Agenda ransomware is via logging in to public-facing servers using stolen credentials. Based on relevant samples and their submission locations reported by VirusTotal, the ransomware has potentially infected targets in South Africa, Romania, Lithuania, India, Thailand, the US, Canada, and Indonesia. It entered the already-crowded ransomware world in mid-June 2022. Agenda RansomwareĪgenda is another Golang-based ransomware. This ransom note contains two contact email addresses and specific instructions victims must follow when sending emails to the attacker.įiles encrypted by BianLian ransomware have a “.bianlian” file extension. It also drops a text file, “HOW TO RESTORE YOUR FILES.TXT”. The latest Snatch ransomware variant encrypts files on the victim’s machine and appends a “.gaqtfpr” extension to the affected files. That not only makes RDP brute-forcing harder but also any other password-guessing attacks. Microsoft enabled an account lockout policy by default, starting with Windows 11 build 22528.1000, that locks user accounts for failed log-in attempts. The reported infection vector of Snatch ransomware is RDP (Remote Desktop Protocol) credential brute-forcing. The file names of its ransom note also differ from variant to variant. However, other file extensions have been observed. Snatch ransomware is a file encryptor that came to be known for using a notable file extension, “.snake”, which it appends to encrypted files. Coincidentally, all other ransomware variants covered in this blog are written in Go. Snatch ransomware is one of the early adopters of the Go programming language as ransomware written in Go was far uncommon compared to today. The Snatch ransomware group made the news towards the end of 2021 when they claimed on their data leak site to have stolen information from a major automobile manufacturer they had compromised. This is unsurprising, as Snatch ransomware has reportedly been active since at least the end of 2018. Impact: Encrypts files on the compromised machine and demands ransom for file decryptionįortiGuard Labs recently came across a new variant of Snatch ransomware. ![]() Impacted parties: Microsoft Windows Users This latest edition covers the Snatch, Agenda, and BianLian ransomware families – all of which are written in the Go programming language (Golang). ![]() The Ransomware Roundup report aims to provide readers with brief insights into the evolving ransomware landscape and the Fortinet solutions that protect against those variants. On a bi-weekly basis, FortiGuard Labs gathers data on ransomware variants of interest that have been gaining traction within our datasets and the OSINT community.
