Information Theft: Risks and Prevention in the AI Age

Information theft costs organizations $4.88M on average. Learn how behavioral AI, Zero Trust architecture, and autonomous response prevent data exfiltration.

What is Information Theft?

Information theft is the unauthorized extraction and transfer of your sensitive data to attacker-controlled infrastructure. The global average cost of a data breach reached $4.4 million in 2025, recorded in IBM's 20-year history of tracking breaches. When your organization faces information theft, you're confronting financial damage, regulatory penalties, operational disruption, and reputational harm that persists long after the initial incident.

How information Theft Relates to Cybersecurity

Information theft sits at the convergence of multiple security disciplines: endpoint protection, identity and access management, data loss prevention, and security operations. Attackers target the gaps between these disciplines. They compromise credentials to bypass authentication, use legitimate cloud storage for data exfiltration to evade network monitoring, and conduct reconnaissance slowly enough to avoid behavioral alerts.

Your security architecture must address the entire attack chain, from initial access through lateral movement to final exfiltration. Traditional perimeter defenses fail when attackers infiltrate your remote workforce, exploit trusted vendor connections, or compromise cloud service accounts with legitimate access credentials. Stopping information theft requires multiple security layers working together.

Impact of Information Theft on Organizations

Information theft creates cascading damage across financial, operational, and reputational dimensions that persists for years after the initial incident. IBM Security research shows the global average cost of a data breach reached $4.88 million in 2024, with healthcare organizations facing $9.77 million average breach costs. These figures represent direct costs, but the full impact extends much further.

• Financial consequences include incident response expenses, forensic investigations, legal fees, regulatory fines, and customer notification costs. Organizations also face class action settlements, credit monitoring services for affected individuals, and increased cyber insurance premiums. The Change Healthcare ransomware attack in February 2024 forced UnitedHealth Group to spend approximately $2.87 billion on response efforts alone.
• Operational disruption halts revenue-generating activities during investigation and recovery. When attackers exfiltrate data before deploying ransomware, your organization faces dual pressure: restoring systems while managing extortion demands. Payment processing freezes, customer service interruptions, and supply chain delays compound direct breach costs.
• Regulatory exposure varies by industry and jurisdiction. GDPR violations can trigger fines up to 4% of annual global revenue. HIPAA penalties reach $1.5 million per violation category annually. State privacy laws including CCPA add additional compliance requirements with their own penalty structures.
• Reputational damage erodes customer trust and investor confidence. Stock prices typically decline following breach announcements, and customer churn accelerates as affected individuals move to competitors. Rebuilding trust requires sustained investment in security improvements and transparent communication. Understanding these impacts reinforces why early identification of theft indicators is essential.

Indicators of Information Theft in an Environment

Your security team should monitor for behavioral and technical anomalies that signal active data exfiltration. Attackers rarely trigger obvious alarms. Instead, they exploit legitimate access patterns and trusted channels to move data out of your environment unnoticed. Recognizing subtle indicators helps you stop theft operations before significant data loss occurs.

• Unusual data transfer patterns represent the most direct indicator. Watch for sudden spikes in outbound traffic, large file transfers to unfamiliar external IP addresses, or data movement to cloud storage services outside your approved list. Attackers often stage data in compressed archives using .zip, .rar, or .7z formats to reduce transfer time and avoid size-based alerts.
• Anomalous user behavior includes access to files or systems outside normal job functions, login attempts from unfamiliar geographic locations, and activity during unusual hours. A finance employee suddenly accessing engineering repositories, or a departing employee downloading customer databases, should trigger immediate investigation. IBM Security research indicates organizations take an average of 85 days to find insider threats, creating substantial windows for undetected exfiltration.
• Network connection anomalies include unexpected outbound connections to unknown servers, traffic on non-standard ports, and DNS queries to suspicious domains. Attackers use DNS tunneling and encrypted channels to bypass traditional security controls. Connections to command-and-control infrastructure often exhibit beaconing patterns with regular intervals between communications.
• Authentication irregularities signal credential compromise. Multiple failed login attempts followed by successful access, simultaneous sessions from different locations, and privilege escalation requests warrant scrutiny. OAuth token theft and session hijacking allow attackers to bypass multi-factor authentication entirely.
• File system changes provide additional warning signs. Mass file access, unauthorized permission modifications, and attempts to disable logging or security tools indicate active theft operations. Wiping or deleting files after copying them suggests attackers are covering their tracks. Mapping these indicators to your monitoring capabilities reveals gaps in your prevention strategy.

Core Components of Information Theft Prevention

Your information theft prevention strategy requires these interconnected components:

• Identity as the control foundation: You need continuous verification of every access request. NIST SP 800-53 Rev. 5 specifies that privileged accounts require credential vaulting, session monitoring, autonomous rotation, and just-in-time privilege elevation.
• Data asset visibility and classification: Autonomous discovery tools locate sensitive information across enterprise systems, cloud storage, and endpoints. Classification taxonomies aligned with business risk enable protection proportional to data sensitivity.
• Behavioral analytics beyond signatures: Signature-based systems fail against zero-day exploits, polymorphic malware, and novel attack techniques. Behavioral analytics establish baselines for normal user behavior, then find anomalies indicating potential theft operations.
• Endpoint posture and device integrity: Device posture assessment validates operating system patch levels, endpoint response status, disk encryption, and firewall configuration before granting access to sensitive resources.
• Threat intelligence integration: MITRE ATT&CK provides a globally-accessible knowledge base of adversary behaviors mapped to 14 tactics and over 200 techniques. Your threat hunting uses ATT&CK as a structured approach for proactive adversary discovery.
• Network segmentation and access controls: Micro-segmentation limits lateral movement by restricting network paths between systems. Role-based access controls ensure users can only reach resources necessary for their functions.
• Incident response and recovery: Documented procedures must include forensic investigation capabilities, containment strategies, and recovery mechanisms that restore operations without paying ransoms.

These components create defense in depth, but deploying them effectively requires understanding exactly how attackers operate.

How Information Theft Works

Understanding attack progression from initial access through data exfiltration helps you identify where your defenses need strengthening.

• Initial access and reconnaissance. Attackers begin with social engineering campaigns targeting your employees. CISA documents Scattered Spider threat actors impersonating helpdesk personnel to direct employees to run commercial remote access tools. Alternatively, attackers exploit vulnerabilities in public-facing applications. CISA's investigation of GeoServer vulnerability CVE-2024-36401 documented threat actors exploiting the vulnerability on July 11, 2024, with CISA adding it to the Known Exploited Vulnerabilities Catalog on July 15, 2024, yet attackers successfully exploited the same vulnerability against victim organizations on July 24, 2024.
• Credential theft and privilege escalation. Following initial access, attackers harvest credentials to expand their foothold. The FBI documented threat actor group UNC6395 conducting OAuth and refresh token theft from Drift integrations in September 2025, demonstrating how attackers use legitimate authentication tokens to bypass security controls. Once inside, they deploy reconnaissance tools to locate high-value data repositories.
• Lateral movement and persistence. Attackers move laterally using compromised credentials and exploited trust relationships. CISA's Medusa ransomware advisory (AA25-071a) demonstrates systematic termination of backup and security-related services across victim networks, employing MITRE ATT&CK techniques including T1027.013 (obfuscated code), T1569.002 (system services abuse), and T1489 (service stop).
• Data identification and staging. Threat actors systematically identify and stage high-value data before exfiltration, targeting intellectual property, customer databases, and financial records. IBM Security research shows organizations take an average of 85 days to find insider threats, creating substantial windows for data exfiltration without triggering alerts.
• Exfiltration and extortion. Modern information theft employs double extortion tactics. CISA's Interlock ransomware advisory explains attackers executing AzCopy to exfiltrate data to Azure storage and using WinSCP for file transfers, creating dual leverage through operational disruption and data exposure threats. Each stage of this attack chain represents an opportunity for your defenses to intervene.

Techniques Used by Threat Actors

Attackers combine multiple techniques to steal your data while evading security controls. Understanding these methods helps you identify coverage gaps in your defenses and prioritize security investments.

Social engineering and phishing remain the primary entry points for information theft operations. Attackers craft targeted spear-phishing emails that impersonate executives, vendors, or IT support staff. CISA's Scattered Spider advisory documents threat actors calling employees while posing as helpdesk personnel, directing them to credential harvesting sites or instructing them to install remote access tools. Voice phishing (vishing) and SMS phishing (smishing) bypass email security controls entirely.

• Credential harvesting and abuse follows successful social engineering. Attackers deploy keyloggers, steal browser-stored passwords, and extract credentials from memory using tools like Mimikatz. The FBI documented threat actor group UNC6395 stealing OAuth tokens and refresh tokens from third-party integrations, allowing persistent access without triggering password-based alerts. Stolen credentials let attackers move through your environment as legitimate users.
• Living-off-the-land techniques use your own tools against you. Attackers execute PowerShell scripts, leverage Windows Management Instrumentation (WMI), and abuse remote administration tools already present in your environment. These techniques blend with normal administrative activity, making them difficult to distinguish from legitimate operations. MITRE ATT&CK catalogs these under techniques like T1059 (Command and Scripting Interpreter) and T1047 (Windows Management Instrumentation).
• Cloud storage abuse exploits trusted services for data exfiltration. Attackers upload stolen data to legitimate cloud platforms like Azure Blob Storage, AWS S3, or consumer services like Google Drive and Dropbox. CISA's Interlock ransomware advisory documents attackers using AzCopy to transfer data to attacker-controlled Azure storage. Your network monitoring often allows this traffic because the destination domains appear legitimate.
• Encrypted tunneling and covert channels hide data transfers from inspection. DNS tunneling encodes stolen data within DNS queries to attacker-controlled domains. HTTPS connections to command-and-control servers blend with normal web traffic. Some attackers use steganography to embed data within image files or leverage protocols like ICMP that security tools often ignore.
• Double extortion ransomware now includes data theft as standard practice. Groups like Medusa, BlackCat, and Interlock exfiltrate sensitive data before encrypting systems, creating leverage even if you restore from backups. CISA advisories document these groups systematically identifying and staging high-value data, then threatening public exposure alongside operational disruption. Stopping these attacks requires finding theft activity before encryption begins.

Key Benefits of Information Theft Prevention

Your investment in information theft prevention delivers measurable organizational value beyond regulatory compliance.

• Quantified cost avoidance. IBM Security research documents that organizations with severe security staffing shortages faced breach costs averaging $1.76 million higher compared to adequately staffed organizations, while healthcare organizations experienced $9.77 million average breach costs. Your prevention investments protect shareholder value and revenue-generating operations.
• Intellectual property preservation. The FBI designates economic espionage and trade secret theft as top counterintelligence priorities, operating the Counterintelligence Strategic Partnership Program (CISPP) to help organizations protect sensitive technologies. When your IP represents competitive advantage worth millions, prevention investments demonstrate clear return on investment.
• Regulatory risk reduction. You face regulatory penalties under frameworks including GDPR, CCPA, HIPAA, and industry-specific requirements. Documented prevention efforts aligned with NIST Cybersecurity Framework 2.0 demonstrate due diligence and reduce legal exposure. These benefits are substantial, but realizing them means overcoming real operational obstacles.

Challenges in Information Theft Prevention

You face persistent obstacles despite significant security investments.

• Tool sprawl and integration failures. Your security environment likely contains 10-40+ disparate tools that don't effectively share data or correlate events. Each additional tool requires separate credentials, different interfaces, and unique alert formats. Purple AI handles routine investigation tasks autonomously, reducing analyst triage burden without adding to tool sprawl.
• Alert fatigue. Signature-based systems fail against zero-day exploits and customized attacks designed to evade known signatures. Your analysts face false positives where benign activities are flagged as malicious. Modern attacks adapt in real-time, requiring behavioral analytics rather than static signature matching.
• Identity and access management gaps. IAM implementations often contain overprivileged accounts with unnecessary permissions. Insufficient monitoring of privileged activities creates blind spots where compromised credentials enable lateral movement before discovery. Singularity Identity provides real-time defense against credential abuse and privilege escalation across hybrid identity environments.
• Supply chain visibility. Attackers increasingly target your supply chain, compromising less-secure vendors to gain access to your better-protected environment. This extended attack surface is difficult to monitor and control. These challenges are compounded when organizations make avoidable errors in their security approach.

Common Mistakes in Information Theft Prevention

Your organization likely makes preventable errors that increase information theft risk.

• Relying exclusively on perimeter defense. Your network perimeter can't keep attackers out when remote workforce, cloud services, and vendor connections bypass traditional boundaries. NIST Special Publication 800-207 establishes that Zero Trust architecture is required, with continuous verification of every access request regardless of origin. Singularity Platform delivers Zero Trust verification across endpoints, cloud workloads, and identity systems.
• Delaying vulnerability patching. The GeoServer CVE-2024-36401 case study demonstrates threat actors actively exploiting a known vulnerability for 13 days after CISA added it to the Known Exploited Vulnerabilities Catalog. Extended patch cycles create windows where attackers exploit published vulnerabilities.
• Treating insider threats as IT issues. You need formal insider threat detection programs with executive sponsorship and cross-functional teams including HR, legal, IT security, and management. 
• Annual compliance training only. Once-per-year training doesn't address emerging social engineering tactics. The SANS Security Awareness Report 2025 found that 80% of organizations rank social engineering as the number one human-related risk. Continuous learning with behavioral change metrics proves more effective. Avoiding these mistakes is the first step; implementing proven practices is the next.

Information Theft Prevention Best Practices

You need strategies aligned with authoritative frameworks from NIST, CISA, and MITRE.

• Implement Zero Trust architecture. NIST Special Publication 800-207 defines Zero Trust as minimizing uncertainty in enforcing accurate, least privilege per-request access decisions. Assume adversaries are present, continuously verify all resource access, grant minimum necessary access, and authenticate all requests. Begin with identity as your foundation, implement micro-segmentation, and deploy continuous monitoring.
• Deploy risk-based identity management. NIST Special Publication 800-63-3 requires organizations to implement risk-based authentication with multiple factors and continuous validation. Privileged accounts require credential vaulting, session monitoring, autonomous password rotation, and just-in-time privilege elevation.
• Establish data classification controls. NIST SP 1800-28 provides guidance on data confidentiality and asset protection. Deploy encryption for data at rest, in transit, and in use. Implement DLP policies at network, endpoint, and cloud levels.
• Map controls to MITRE ATT&CK. Map existing security controls to ATT&CK techniques to identify coverage gaps. Conduct purple team exercises using ATT&CK scenarios to validate that deployed controls stop documented adversary techniques.
• Develop formal insider threat programs. CISA's Insider Threat Prevention Guide emphasizes that effective programs require executive sponsorship and cross-functional teams. Deploy User and Entity Behavior Analytics (UEBA) that establish baselines and find anomalies.
• Implement supply chain risk management. NIST SP 800-161 Rev. 1 establishes frameworks for third-party risk assessment. Include cybersecurity requirements in supplier contracts and conduct routine assessments. Cloud security extends visibility across multi-cloud environments where supply chain vulnerabilities hide. Executing these practices at scale requires security platforms purpose-built for autonomous protection.

Examples of Information Theft Attacks

Real-world incidents reveal how attackers execute information theft and what failures enable their success. These cases demonstrate the techniques, costs, and organizational impact covered throughout this guide.

• Change Healthcare (February 2024) stands as one of the most damaging healthcare information theft incidents in U.S. history. The BlackCat (ALPHV) ransomware group infiltrated Change Healthcare systems, exfiltrated sensitive patient data, and deployed ransomware that halted medical claims processing nationwide. Patients paid out-of-pocket for medications while providers lost revenue from frozen billing systems. UnitedHealth Group, Change Healthcare's parent company, reported in its Q3 2024 SEC filing that response costs reached approximately $2.87 billion in 2024. In Congressional testimony, CEO Andrew Witty confirmed the attackers gained initial access through compromised credentials on a Citrix portal lacking multi-factor authentication.
• Snowflake Customer Breaches (2024) affected major organizations, including Ticketmaster, AT&T, and Santander, through a single attack vector. A threat actor tracked by Mandiant as UNC5537 used stolen credentials to access customer environments hosted on Snowflake's cloud data platform. None of the compromised accounts had MFA enabled, and some credentials had been available on criminal marketplaces for years. The Ticketmaster breach exposed data on approximately 560 million customers, while AT&T lost records containing call and text metadata for nearly all its mobile customers. These incidents show how credential theft, combined with weak authentication, creates catastrophic exposure across multiple organizations.
• Salt Typhoon Telecom Attacks (2024) targeted major U.S. telecommunications providers, including AT&T, Verizon, T-Mobile, and Lumen Technologies. The Chinese state-sponsored group accessed call and text metadata, geolocation information, and, in some cases, actual audio recordings. The FBI and CISA joint statement confirmed the campaign targeted commercial telecommunications infrastructure, and CISA issued hardening guidance for communications infrastructure in response.
• MOVEit Transfer Exploitation (2023-2024) exploited a zero-day vulnerability in Progress Software's file transfer application. The Cl0p ransomware group systematically targeted organizations using MOVEit, exfiltrating data before victims could patch. The CISA and FBI joint advisory (AA23-158A) documented that beginning May 27, 2023, Cl0p exploited SQL injection vulnerability CVE-2023-34362 to install a web shell named LEMURLOOT on MOVEit Transfer web applications. Nearly 80% of victims were U.S. corporations, including the Department of Energy, Johns Hopkins University, and the NYC Department of Education. The incident illustrates how supply chain vulnerabilities in trusted software create widespread information theft opportunities.

These attacks share common threads: credential compromise, inadequate authentication controls, and delays between initial access and discovery. Stopping information theft requires autonomous protection that acts faster than human response times allow.

Stop Information Theft with SentinelOne

SentinelOne stops attackers from stealing the data that matters most — from endpoints and identities to cloud workloads, object storage, and AI models. The Singularity™ Platform unifies prevention, detection, and response so security teams can see and shut down information theft attempts in real time.

Shut Down Data Theft on Endpoints and Identities

Singularity™ Endpoint and Singularity™ Identity work together to stop credential abuse, privilege escalation, and data exfiltration from user devices and directories. Storyline reconstructs the full attack story in milliseconds and maps it to MITRE ATT&CK, so analysts can immediately see how an intrusion is progressing toward data theft. 

Endpoint Firewall Control and Device Control lock down risky egress paths by restricting outbound connections and blocking or limiting untrusted USB and Bluetooth devices, preventing attackers from walking off with sensitive files. Singularity™ Mobile extends this protection to iOS, Android, and ChromeOS, stopping phishing, man‑in‑the‑middle attacks, and malicious apps that silently siphon data from phones and tablets. When ransomware operators try double extortion, (encrypting data and exfiltrating it for leverage) automated containment and 1‑click Rollback help ensure there are safe copies of data to restore, removing the attacker’s ability to extort the organization.

Converge Endpoint and Identity for Complete Coverage

Because most data theft starts with stolen credentials, SentinelOne converges endpoint telemetry with identity context. Singularity™ Identity continuously monitors Active Directory and cloud identity providers to surface misconfigurations, risky privileges, and exposed credentials before attackers can exploit them. Deception techniques, high‑fidelity alerts, and automated remediation detect and stop credential theft, lateral movement, and directory attacks in real time. Combined with the deep endpoint visibility of Singularity™ Endpoint, security teams gain end‑to‑end coverage of how users, devices, and identities are being targeted so they can contain information theft early in the kill chain.

Protect AI Models and Prevent Data Exfiltration from Prompts

As organizations adopt generative AI, attackers are increasingly trying to exfiltrate sensitive training data, secrets, and intellectual property directly from models. Prompt Security by SentinelOne protects AI tools and services against prompt injection, data‑harvesting attacks, and shadow AI usage. Guardrails enforce which data models can access, while real‑time monitoring detects and blocks attempts to trick models into revealing confidential information or exposing sensitive outputs. This keeps customer data, proprietary models, and internal knowledge bases from being turned into an exfiltration channel.

Secure Cloud Workloads, Storage, and Data with CNAPP, AI SPM, and DSPM

Singularity™ Cloud Security delivers an AI‑powered CNAPP that unifies Cloud Security Posture Management, AI Security Posture Management (AI SPM), Data Security Posture Management (DSPM), and Cloud Detection and Response to stop information theft across cloud environments.

FAQs

What is Information Theft?

Information theft is the unauthorized extraction and transfer of sensitive data from your organization to attacker-controlled infrastructure. Attackers target customer records, financial data, intellectual property, credentials, and protected health information. 

The stolen data enables identity fraud, corporate espionage, extortion demands, and sale on criminal marketplaces. Information theft differs from accidental data exposure because attackers deliberately identify, stage, and exfiltrate high-value assets through planned operations.

How does Information Theft Occur?

Attackers typically gain initial access through phishing, compromised credentials, or exploiting vulnerabilities in public-facing applications. Once inside, they conduct reconnaissance to locate valuable data, move laterally using stolen credentials or trust relationships, and stage files for exfiltration. 

Data leaves your environment through encrypted channels, cloud storage services, DNS tunneling, or direct transfers to attacker infrastructure. Modern ransomware groups now exfiltrate data before deploying encryption, creating double extortion scenarios.

What are the Common Types of Information Theft?

The most common types include credential theft, where attackers harvest usernames and passwords through phishing or malware; customer data theft targeting personally identifiable information and payment card data; intellectual property theft focused on trade secrets, source code, and proprietary research; healthcare data theft involving protected health information subject to HIPAA; and insider theft where employees or contractors misuse authorized access to steal data. 

Each type carries distinct regulatory, financial, and reputational consequences.

What are the high-value targets for Information Theft?

Attackers prioritize data with immediate monetary value or strategic importance. High-value targets include customer databases containing names, addresses, Social Security numbers, and payment information; authentication credentials for privileged accounts and administrative systems; intellectual property such as product designs, manufacturing processes, and research data; 

Healthcare records containing diagnoses, treatments, and insurance information; financial records including banking details, transaction histories, and accounting data; and government or defense information with national security implications.

How to Detect Information Theft?

Watch for unusual data transfer patterns including large outbound transfers, connections to unfamiliar IP addresses, and traffic to unapproved cloud storage services. Monitor user behavior for access outside normal job functions, logins from unusual locations, and activity during off-hours. Track authentication anomalies such as failed login attempts followed by successful access, simultaneous sessions from different locations, and privilege escalation requests. 

File system indicators include mass file access, compressed archive creation, and attempts to disable logging. Behavioral analytics that establish baselines and find deviations prove more effective than signature-based approaches.

How to Prevent Information Theft?

Start with identity as your control foundation by implementing multi-factor authentication, privileged access management, and continuous verification of access requests. Deploy data classification to identify sensitive assets and apply protection proportional to their value. Implement Zero Trust architecture that assumes adversaries are present and validates every resource request. 

Use behavioral analytics to find anomalies that signature-based tools miss. Establish network segmentation to limit lateral movement. Deploy endpoint protection with autonomous response capabilities that act faster than human analysts. Develop formal insider threat programs with cross-functional oversight.

How does information theft differ from traditional data breaches?

Information theft represents the attacker's objective of systematically extracting and transferring your sensitive data through data exfiltration. Data breaches are the resulting security incidents when systems are compromised. 

Modern information theft operations conduct extensive reconnaissance to identify valuable assets, stage data for exfiltration, and employ double extortion tactics combining operational disruption with data exposure threats.

What role does identity security play in preventing information theft?

Identity serves as both the primary attack path and essential control foundation. Attackers compromise credentials through phishing, OAuth token theft, and credential harvesting to bypass perimeter defenses. 

The FBI's documentation of UNC6395 OAuth token theft in September 2025 demonstrates that modern attacks target authentication systems and third-party integrations. Identity and access management with continuous verification and behavioral monitoring addresses this vulnerability.

Why do signature-based systems fail against information theft?

Signature-based systems fail against zero-day exploits, polymorphic malware, and customized attacks designed to evade known signatures. These systems generate both false positives and false negatives, failing to stop threats without known signatures. 

Information theft operations use legitimate cloud storage and slow reconnaissance that doesn't trigger signature thresholds. Behavioral analytics that establish baselines and find anomalies prove more effective.

How should organizations prioritize information theft prevention with limited budgets?

Start with identity and access management by implementing multi-factor authentication and privileged account controls. This addresses attack paths documented by CISA and FBI advisories. 

Deploy data classification to apply protection proportional to asset value per NIST SP 1800-28. Implement MITRE ATT&CK mapping to identify coverage gaps at no cost. Establish insider threat programs with cross-functional teams.

What metrics measure information theft prevention effectiveness?

Measure mean time to find data exfiltration attempts across attack paths. Track percentage of security controls mapped to MITRE ATT&CK techniques. Monitor privileged account activity coverage and the percentage of administrative actions logged and analyzed. 

Assess false positive rates requiring manual investigation and false negative rates discovered through red team exercises.

What is the relationship between ransomware prevention and information theft?

Modern ransomware operations include data exfiltration as a standard tactic. CISA advisories document threat actors like Medusa and Interlock staging and exfiltrating data before deploying ransomware, creating double extortion scenarios. Effective ransomware prevention must include data exfiltration controls, behavioral analytics to find staging activities, and autonomous response that stops attacks before data leaves your environment.
