Canvas Platform Compromised by ShinyHunters

Arete Analysis

Cyber Threats

Threat Actors

In early May, the ShinyHunters threat group claimed responsibility for a large-scale cyberattack on the Canvas learning management platform, affecting almost 9,000 educational institutions worldwide. Instructure, the education technology company that owns Canvas, confirmed the intrusion and, on May 11th, announced that a settlement was reached with the threat actor. According to the statement, the settlement included return of the stolen data to Instructure, assurance of destruction of any copies of the data, and assurance that no Canvas users would be extorted for additional ransom payments. 

  • Unauthorized activity was first detected in Canvas on April 29th and was reportedly the result of cross-site scripting vulnerabilities. Leveraging the same vulnerability, the threat actor conducted a follow-up attack on May 7th, replacing the login screens of Canvas users at hundreds of institutions with a message from ShinyHunters, claiming responsibility for the attack and displaying a list of impacted schools and the threat actor’s contact information.  

  • By May 8th, neither Canvas nor Instructure was posted on ShinyHunter’s data leak site (DLS), and instead a vague “Press Statement” indicated that the group would not comment on the incident. On May 9th, Instructure shared another update, indicating that Canvas was “fully back online and available for use,” along with updates to the company’s FAQ page.

ShinyHunters: Not Just For Pokémon Anymore 

ShinyHunters is a predominantly English-speaking cybercriminal group first observed in 2020 that focuses on data exfiltration and extortion. During its early operational phase, the group carried out a series of data breaches targeting organizations, including Tokopedia, Wattpad, and Nitro PDF, establishing a reputation for compromising and monetizing large datasets. Over this period, ShinyHunters remained heavily centered on a “pay or leak” model, leveraging stolen data to pressure victims into ransom payments or selling the information on underground forums when demands were not met. 

As the group matured, it evolved beyond opportunistic database theft into a more sophisticated threat actor capable of executing complex, large-scale intrusion campaigns. ShinyHunters has since demonstrated an ability to target higher‑profile industries, including telecommunications, aviation, and enterprise software-as-a-service (SaaS) platforms, by leveraging advanced tactics such as social engineering, SaaS abuse, and supply chain compromise.  

The group went as far as to partner with two other threat groups to form the Scattered Lapsus$ Hunters (SLH) collective in early 2025. Playing to each group’s strengths, SLH leveraged compromised OAuth tokens from the Salesloft Drift integration in an advanced supply-chain attack that led to the exfiltration of data across hundreds of Salesforce instances. Despite multiple law enforcement actions and arrests linked to its members, the group has remained operational under the same branding for several years. This persistence highlights the group’s resilience and adaptability, suggesting an operational model that can evolve in response to external pressures. 

Analyst Comments 

Given the group’s track record, ShinyHunters is likely to continue conducting large-scale data theft and extortion operations while further engraining itself within the broader cybercriminal ecosystem. This recent incident highlights the disproportionate impact of cyberattacks against supply chain vendors like SaaS platforms, open-source ecosystems, MSPs, and cloud integrations, where a breach on one platform can affect thousands of organizations. Any organizations impacted by the recent Canvas incident should not attempt any communication with the threat actor and should continue to follow any future guidance posted on Instructure’s Incident Update & FAQ page.

Europol Disrupts AudiA6 Crypto Laundering Service

European authorities have dismantled AudiA6, a major cryptocurrency laundering service linked to ransomware groups and broader cybercriminal networks. Between 2022 and 2025, the platform is believed to have processed over €336 million in illicit funds, enabling threat actors to obscure financial trails and monetize cybercrime proceeds. Its operators are also suspected of running Dark2Web, a dark web forum that facilitated collaboration, services, and connections among cybercriminals globally. This development underscores the expanding role of sophisticated, large-scale cryptocurrency laundering services in sustaining the cybercrime economy, enabling threat actors to obscure illicit funds and evade regulatory controls.

What’s Notable and Unique 

  • Following law enforcement disruption of Cryptex and Garantex, AudiA6 emerged as another platform involved in financial activities linked to ransomware groups. Investigators believe that AudiA6 became a central hub for cybercriminals seeking to launder stolen digital assets while obscuring the transaction trail from authorities.

  • On June 10, 2026, a coordinated operation resulted in two arrests in Georgia, the dismantling of key infrastructure (30+ servers, 25 domains), the freezing or seizure of over €778,000 in crypto, and the takedown of the AudiA6 and Dark2Web platforms. 

Analyst Comments

Ransomware groups and cybercriminal networks are increasingly leveraging sophisticated techniques, including chain-hopping, decentralized exchanges, and mixer-as-a-service platforms, to rapidly move illicit cryptocurrency across multiple blockchains, effectively obscuring transaction trails. Concurrently, the widespread use of fraudulent exchange accounts, mule wallets, and privacy-enhancing tools has elevated cryptocurrency laundering to a core enabler of the cybercrime ecosystem, allowing actors to bypass anti-money-laundering controls at scale. This investigation identified over 6,000 KYC records linked to money-mule accounts, many of which were tied to Russian-speaking intermediaries specifically recruited to facilitate the movement of illicit proceeds. These threat actors systematically used both commercial and domain-controlled email services to establish mule accounts across multiple cryptocurrency platforms. Collectively, these findings underscore the growing scale, coordination, and professionalization of cryptocurrency-enabled crime, highlighting the critical need for sustained, intelligence-led, and internationally coordinated efforts to disrupt these evolving financial ecosystems.

Threat Actors Leverage AI for EDR Evasion

A threat actor has developed and deployed a ransomware attack toolkit enhanced with AI-assisted development workflows, enabling automated Active Directory (AD) discovery and improved EDR evasion capabilities. The toolkit leverages agent-based AI systems, such as Claude’s Opus and Cursor agents, for iterative malware development, testing, and refinement. 

What’s Notable and Unique 

  • Researchers have highlighted that this toolkit can not only generate ransomware code but also bypass sophisticated security defenses and identify AD networks for malware distribution. 

  • The framework incorporates multiple capabilities, including automated AD discovery and reconnaissance mechanisms, iterative EDR testing environments to refine evasion techniques, and a command-and-control (C2) infrastructure that leverages Telegram APIs and Cloudflare redirectors for stealth. 

  • Additionally, some agents were tasked with checking security research and technical posts for various bypass techniques. The agents recognized what was required for reproduction, extracted the techniques, mapped them to the MITRE ATT&CK knowledge base of adversary behaviors, set up a test lab, carried out the methodology, and reported the results. 

  • After a few repetitions, the modules seemed to avoid nearly all EDR solutions, despite the agent’s initial suggestion of a high failure rate. Although researchers found no evidence that AI was embedded in deployed malware or was operating independently in victim environments, the technology was still used to accelerate the iterative process of developing, testing, and refining payloads against security products, shortening the period between the publication of offensive security research and its practical implementation by threat actors. 

Analyst Comments 

AI-driven tools like this could accelerate the pace and sophistication of ransomware attacks, enabling even relatively inexperienced actors to launch high-impact campaigns. This development underscores the urgent need for security solutions to adapt to AI-assisted threats. Organizations must respond by strengthening detection engineering, improving visibility across environments, and maintaining robust security fundamentals.

CMS Vulnerability Leads to ClickFix Campaign

Threat actors compromised at least 700 education and technology websites in a recent ClickFix campaign by exploiting a critical SQL injection flaw (CVE-2026-26980) in the Ghost content management system (CMS). Adversaries combined the vulnerability with the ClickFix social engineering tactic to steal admin keys and inject a malicious JavaScript that delivers a fake Cloudflare or CAPTCHA verification pop-up, tricking victims into copying and pasting a malicious command into their systems.

What’s Notable and Unique

  • Rather than targeting the end user first, this campaign is unique in its initial exploitation of the system, followed by social engineering attempts. This hybrid attack style is likely being leveraged to bypass traditional defenses.

  • This recent campaign also highlights how trusted web properties can be weaponized at scale and coupled with unpatched CMS vulnerabilities. Rather than using the CMS compromise to perpetrate a single attack, threat actors turned it into a supply-chain attack that ultimately affected over 700 trusted websites.

Analyst Comments

As network defenders and their tools enhance threat detection capabilities, adversaries increasingly seek methods to bypass these defenses. By combining vulnerability exploitation, social engineering techniques, and staging for ancillary attacks, this campaign successfully bypassed traditional defenses and inflicted significant impact. Defending against hybrid cyberattacks requires comprehensive security controls beyond simply patching vulnerabilities. Organizations should focus on limiting movement within the environment, detecting abuse of trusted applications, and preventing end-user manipulation.
