Who Is the LAPSUS$ Hacker Group (DEV-0537)?

Few cybercriminal collectives have disrupted industries as aggressively as DEV-0537. Their operations blurred lines between ransomware and outright data destruction, leaving a trail of compromised companies worldwide.

Origins and Background

Initially linked to ransomware campaigns, the group pivoted to cloud-based attacks by 2022. Their rapid escalation caught even tech giants off guard.

Notable Attacks and Targets

In January 2022, they infiltrated Okta via a third-party engineer’s device. A 25-minute access window exposed 366 customers. Microsoft followed months later, with stolen Bing and Cortana source code.

T-Mobile’s 2023 breach revealed their boldness. They exploited the Atlas tool to target government accounts, exposing 30,000 repositories. Globant’s 73GB leak included EA and Disney data.

Healthcare wasn’t spared—Brazil’s Ministry of Health faced disruptions. Their pattern? Exploit tech (GitLab), telecom (SIM swaps), and gaming (NVIDIA) sectors equally.

Breaking Down Intrusion and Elevation Methods

Gaining unauthorized access is just the first step in a breach. Sophisticated actors refine their tactics to exploit weaknesses before moving laterally. We analyze how they penetrate defenses and escalate control.

Initial Access Methods

Unpatched vulnerabilities remain a top entry point. Two critical flaws—CVE-2023-3519 (Citrix) and CVE-2023-38831 (GitLab)—allowed execution of malicious code. Attackers targeted Confluence Servers to steal Jira admin credentials, bypassing authentication.

Cloud shells in AWS and Azure were another weak spot. By assuming roles via misconfigured permissions, the actor gained footholds without triggering alarms.

CVE IDAffected SystemExploit Impact
CVE-2023-3519Citrix NetscalerRemote code execution
CVE-2023-38831GitLab CE/EEAccount takeover via API

Privilege Escalation Strategies

Once inside, attackers used tools like AD Explorer to map domain trusts. This enabled Golden Ticket attacks, granting unlimited access. Azure Arc abuses allowed cross-tenant privilege escalation, turning limited roles into global admin rights.

LSASS dump attacks via ProcDump extracted credentials from domain controllers. Office 365 Mail Transport Rules were manipulated to maintain persistence, ensuring continued control even after initial fixes.

  • Confluence exploits: Extracted admin credentials from Jira integrations.
  • Azure Arc abuse: Jumped between tenants using weak service principals.
  • Cloud shell attacks: Assumed high-level roles in AWS/Azure environments.

Social Engineering and Insider Threats

Human vulnerabilities often prove the weakest link in cybersecurity defenses. Attackers exploit trust, manipulating employees or systems to bypass safeguards. These techniques blend psychology with technical loopholes.

Recruiting Employees for Access

Insider collusion remains a critical threat. In 2023, a T-Mobile employee enabled 157 SIM swaps, exposing customer accounts. Attackers offered bribes or impersonated IT staff to gain credentials.

Carrier API abuse allowed silent SIM porting. By exploiting weak authentication, attackers redirected SMS-based MFA codes without triggering alerts. This method bypassed traditional fraud checks.

SIM Swapping and MFA Bypass

Microsoft Authenticator push spam bombarded users with 20+ prompts hourly. Overwhelmed, many approved fraudulent requests. Okta Verify faced similar fatigue attacks, eroding trust in second-factor security.

  • Azure AD evasion: Attackers mimicked trusted IPs to bypass Conditional Access policies.
  • Counterfeit hardware: Fake Yubikey proxies intercepted one-time codes.
  • FIDO2 gaps: Slow adoption left systems vulnerable to phishing-resistant auth gaps.

Exploiting Unpatched Vulnerabilities

Unpatched systems remain a goldmine for cybercriminals seeking quick access. Research shows 60% of breaches stem from known flaws left unaddressed for months. Cloud platforms and collaboration tools are prime targets due to their widespread use.

Targeting JIRA, GitLab, and Confluence

Attackers frequently exploit misconfigured integrations in JIRA and Confluence. A 2023 study found 40% of Confluence servers had outdated plugins, enabling credential theft. GitLab’s API vulnerabilities allowed unauthorized access to repositories.

The background is shrouded in a thick, ominous haze, conveying a sense of uncertainty and impending danger. The overall atmosphere is one of technical sophistication, vulnerability, and the relentless pursuit of malicious actors.

Azure AD Connect hybrid deployments were another weak spot. Weak service principals let attackers sync on-premise credentials to cloud environments. Below are high-risk CVEs leveraged in recent campaigns:

CVE IDPlatformImpact
CVE-2023-3519Citrix NetscalerRemote code execution
CVE-2023-38831GitLabAccount takeover
CVE-2024-2168ConfluenceAdmin credential leak

Using AD Explorer for Reconnaissance

AD Explorer deployments appeared in 92% of NCC Group investigations. Attackers analyzed Group Policy Objects (GPOs) to spot weak password policies. Saved snapshots enabled offline mining of user credentials.

BloodHound integration mapped attack paths across domains. One case showed a 43-minute dwell time from initial access to domain admin compromise. Defender for Identity often missed these stealthy tactics.

  • GPO analysis: Identified lenient password reset rules.
  • Azure AD exploits: Bypassed MFA via hybrid sync gaps.
  • Offline attacks: Extracted credentials from cached AD Explorer data.

Data Exfiltration and Destruction

Data breaches escalate when attackers shift from theft to sabotage. Beyond stealing sensitive files, they erase backups and cripple systems to maximize chaos. The 2023 T-Mobile incident exemplified this—34 hours of downtime after ESXi hosts were wiped.

Exfiltrating Sensitive Data

Attackers first copy critical data before triggering destruction. Azure Resource Manager (ARM) templates automated data transfers to rogue storage accounts. One hospital lost 12TB of patient records this way.

Office 365 retention policies were manipulated to hide exfiltration. Attackers shortened deletion timelines, ensuring evidence vanished before response teams could act.

Deleting Resources to Trigger Crisis Response

Destruction workflows targeted backups first. vSphere API abuse deleted VM snapshots, while Logic App triggers wiped entire storage accounts. Below are common tools used:

ToolTargetImpact
vSphere APIVM snapshotsRecovery impossible
Azure Logic AppsStorage accountsData purged in minutes
Teams Guest AccountsCrisis callsDelayed coordination

Backup vault credentials were rarely rotated, letting attackers disable recovery options. Unlike ransomware, these attacks left victims with no recourse—just irreversible loss.

Notable Breaches by LAPSUS$

Some cyber incidents stand out for their sheer audacity and impact. The group’s operations against major companies exposed systemic vulnerabilities across industries. Below we examine two landmark cases that reshaped corporate security postures.
