S0575: Conti

Conti is a Ransomware-as-a-Service (RaaS) that was first observed in December 2019. Conti has been deployed via TrickBot and used against major corporations and government agencies, particularly those in North America. As with other ransomware families, actors using Conti steal sensitive files and information from compromised networks, and threaten to publish this data unless the ransom is paid.[1][2][3]

Glexia's Take · Automated analysis

Security context for executives and security teams

Automation confidenceHigh

Conti matters because ATT&CK describes it as Windows ransomware-as-a-service associated with data theft, extortion pressure, and encryption for impact. For leaders, the decision value is not simply “detect Conti,” but to validate whether the organization can see and contain the behaviors ATT&CK links to it: discovery of systems, shares, files, processes, network connections, lateral movement over SMB/admin shares, service stopping, recovery inhibition, and data encryption.

Executive priority

Prioritize Conti as a resilience and incident-readiness scenario. The supplied ATT&CK context ties it to ransomware intrusions, major corporations and government agencies, deployment via TrickBot, and use in campaign C0015 with Bazar and Cobalt Strike. Executives should ask whether backups are recoverable, whether sensitive-file exposure can be investigated quickly, whether Windows lateral movement is constrained, and whether SOC/IR teams have evidence to reconstruct a 5-day ransomware intrusion pattern if needed.

Technical view

ATT&CK provides no official detection text for Conti, so defenders should validate coverage through the related behaviors rather than a single malware signature. On Windows, focus on command-shell execution, native API/process activity, DLL injection indicators, network and share discovery, file/directory enumeration, SMB/Windows admin share use, tainted shared content, service stop activity, recovery inhibition, and encryption-impact patterns. Relationship context to C0015 suggests detections should also be tested in intrusion chains involving other tooling, not only the final ransomware payload.

Likely telemetry

  • Windows endpoint process creation and command-line telemetry
  • Parent/child process relationships around cmd.exe and administrative utilities
  • Windows service control events and service stop/disable activity
  • File creation, modification, rename, and high-volume encryption-like activity on local and shared storage
  • SMB, Windows admin share, and network share access logs

Detection direction

  • Do not rely on a Conti-specific alert alone; ATT&CK supplies no official detection guidance for this object.
  • Map detections to the related ATT&CK techniques: discovery, SMB/admin share lateral movement, stealth through obfuscation or DLL injection, command-shell/native API execution, service stopping, recovery inhibition, and data encryption for impact.
  • Tune for ransomware-stage clustering: rapid discovery plus share access plus service-stop or recovery-inhibition activity is more meaningful than any single administrative command.
  • Account for false positives from administrators, backup tools, software deployment, vulnerability scanners, and file indexing systems that may perform discovery or high-volume file access.
  • Validate file-server and endpoint visibility together; shared-content tainting, network share discovery, and SMB lateral movement can be missed if only workstation telemetry is reviewed.

Mitigation priorities

  • Confirm offline or otherwise resilient backups and test restoration procedures before relying on them as ransomware mitigation.
  • Restrict and monitor SMB/admin share usage, especially where valid accounts can access many Windows systems.
  • Reduce unnecessary shared-write locations and monitor changes to shared content that could support lateral movement.
  • Harden identity and privilege paths used for remote administration; Conti-related techniques depend heavily on discovery and movement through accessible systems and shares.
  • Protect recovery mechanisms from routine administrative compromise, including controls around backup catalogs, recovery services, and shadow copy management where applicable.
Additional notes and limits

This take is based on the supplied ATT&CK S0575 object, its external references, and relationships. ATT&CK describes Conti as RaaS first observed in December 2019, deployed via TrickBot, used against major corporations and government agencies particularly in North America, and associated with theft of sensitive files plus ransom publication threats. ATT&CK also links the software to campaign C0015 and group G0102 Wizard Spider.

The official object does not provide detection text, aliases, labels, or object-level tactics. Platform support for the malware object is Windows, although several related techniques list broader platforms. Local validation is required to determine actual exposure, telemetry quality, control coverage, and whether any Conti-related activity exists in a specific environment.

This mirrors the MITRE pattern of making group, software, campaign, and technique relationships scannable. Relationship notes come from mirrored ATT&CK relationship text when available.

16 rows
DomainIDNameRelationship / procedure
EnterpriseT1021.002SMB/Windows Admin SharesSub-technique

Conti can spread via SMB and encrypts files on different hosts, potentially compromising an entire network.[1][2]

EnterpriseT1135Network Share Discovery

Conti can enumerate remote open SMB network shares using NetShareEnum().[2][4]

EnterpriseT1140Deobfuscate/Decode Files or Information

Conti has decrypted its payload using a hardcoded AES-256 key.[1][2]

EnterpriseT1489Service Stop

Conti can stop up to 146 Windows services related to security, backup, database, and email solutions through the use of net stop.[2]

EnterpriseT1083File and Directory Discovery

Conti can discover files on a local system.[2]

EnterpriseT1016System Network Configuration Discovery

Conti can retrieve the ARP cache from the local system by using the GetIpNetTable() API call and check to ensure IP addresses it connects to are for local, non-Internet, systems.[2]

EnterpriseT1486Data Encrypted for Impact

Conti can use CreateIoCompletionPort(), PostQueuedCompletionStatus(), and GetQueuedCompletionPort() to rapidly encrypt files, excluding those with the extensions of .exe, .dll, and .lnk. It has used a different AES-256 encryption key per file with a bundled RAS-4096 public encryption key that is unique for each victim. Conti can use “Windows Restart Manager” to ensure files are unlocked and open for encryption.[1][2][3][4][5]

EnterpriseT1018Remote System Discovery

Conti has the ability to discover hosts on a target network.[4]

EnterpriseT1027Obfuscated Files or Information

Conti can use compiler-based obfuscation for its code, encrypt DLLs, and hide Windows API calls.[2][1][4]

EnterpriseT1490Inhibit System Recovery

Conti can delete Windows Volume Shadow Copies using vssadmin.[2]

EnterpriseT1049System Network Connections Discovery

Conti can enumerate routine network connections from a compromised host.[2]

EnterpriseT1055.001Dynamic-link Library InjectionSub-technique

Conti has loaded an encrypted DLL into memory and then executes it.[1][2]

EnterpriseT1080Taint Shared Content

Conti can spread itself by infecting other remote machines via network shared drives.[1][2]

EnterpriseT1059.003Windows Command ShellSub-technique

Conti can utilize command line options to allow an attacker control over how it scans and encrypts files.[2][5]

EnterpriseT1057Process Discovery

Conti can enumerate through all open processes to search for any that have the string “sql” in their process name.[2]

EnterpriseT1106Native API

Conti has used API calls during execution.[1][2]

G0102: Wizard Spider

Wizard Spider is a Russia-based financially motivated threat group originally known for the creation and deployment of TrickBot since at least 2016. Wizard Spider possesses a diverse arsenal of tools and has conducted ransomware campaigns against a variety of organizations, ranging from major corporations to hospitals.[1][2][3]

C0015: C0015

C0015 was a ransomware intrusion during which the unidentified attackers used Bazar, Cobalt Strike, and Conti, along with other tools, over a 5 day period. Security researchers assessed the actors likely used the widely-circulated Conti ransomware playbook based on the observed pattern of activity and operator errors.[1]
