Unveiled: Concealed Ties among Ransomware Groups and Their Alliances Unraveled by Researchers
In the ever-evolving world of cybersecurity, a new trend is emerging among ransomware groups. A fractured ecosystem, marked by human-driven modularity and rapid rebranding, is challenging traditional defenses. This article delves into the tactics and alliances of notable ransomware families like Black Basta, QakBot, and others.
First, let's discuss Black Basta. This ransomware group, known for its in-memory injection techniques, bypasses traditional antivirus scans by leveraging legitimate system binaries to blend in with normal operations. Moreover, their use of fileless deployment and persistence tactics is designed to evade endpoint defenses.
A comparative disassembly of the loader stages for both Black Basta and QakBot highlights identical opcode sequences in the memory-resident decryptor, indicating potential code reuse or direct lineage. The PowerShell loader used by Black Basta employs Windows API's and functions to inject a second-stage payload directly into the process.
Meanwhile, QakBot, a long-standing player in the ransomware scene, employs Affine key indexing for polymorphic encryption across multiple malware families, complicating signature-based detection.
The ransomware landscape has become increasingly interconnected, with several groups collaborating through dynamic ransomware-as-a-service (RaaS) marketplaces. These collaborations combine technical ransomware deployment with sophisticated social engineering tactics to enhance attack impact and efficiency. Groups like DragonForce, Qilin, Scattered Spider, ALPHV, RansomHub, and others have been observed working together in this manner.
This cooperative model facilitates industrialized ransomware operations, with affiliate commissions up to 80%, allowing rapid scaling, resilience against law enforcement disruptions, and a blending of skills that challenge defenders' traditional perceptions of ransomware threats as isolated and distinct actors.
Attackers use exposed RDP services or phishing vectors to deploy a lightweight PowerShell loader in memory, bypassing traditional AV scans. Passive DNS records, shared SSL certificates, and duplicate command-and-control domains reveal that multiple groups have leveraged the same bulletproof hosting providers.
Domaintools analysts have identified overlapping infrastructure footprints and shared binary artifacts that point to resource pooling rather than isolated criminal factions. This finding underscores the necessity for defenders to track underlying assets and behaviours instead of surface-level brand labels.
In conclusion, understanding these hidden alliances and infection tactics can help cybersecurity teams prioritize detection of shared infrastructure and code patterns. By focusing on these shared elements, teams can develop more resilient defenses against a threat landscape defined by human-driven modularity and rapid rebranding.
