The compromise, initially disclosed by Live Nation, affected 165 Snowflake customers, impacting major corporations such as Ticketmaster, AT&T, and Santander Bank. The breaches were investigated by the cybersecurity firm Mandiant, which confirmed that attackers used stolen login credentials acquired via infostealer malware. The compromised accounts were not protected by multi-factor authentication, making them susceptible to unauthorized access. Moucka and his cybercrime group, identified as UNC5537, exploited these vulnerabilities to carry out their attacks. The investigation revealed that Moucka boasted about his successful hacks on Telegram and had demanded ransom payments from affected organizations to prevent the sale of stolen data on the dark web. Some companies, facing significant financial and reputational damage, opted to pay the ransoms. Moucka's arrest came at the request of the United States, and he is currently facing legal proceedings with potential extradition to the U.S. Authorities emphasize the importance of organizations properly configuring and monitoring their SaaS applications to avoid similar breaches in the future. ## Similar posts on daily.dev - [Don’t just attend KubeCon \+ CloudNativeCon, Merge Forward your experience\!](https://daily.dev/posts/don-t-just-attend-kubecon-cloudnativecon-merge-forward-your-experience--l0rpp73x8) · CNCF · 1 upvotes · 0 comments - [Announcing H2 2026 KCDs](https://daily.dev/posts/announcing-h2-2026-kcds-m96goajm1) · CNCF · 1 upvotes · 0 comments - [Two months of Open Community Groups](https://daily.dev/posts/two-months-of-open-community-groups-asf52zhbs) · CNCF · 0 upvotes · 0 comments - [CNCF Unveils Schedule for KubeCon \+ CloudNativeCon Europe 2026](https://daily.dev/posts/cncf-unveils-schedule-for-kubecon-cloudnativecon-europe-2026-ikhcoa5cb) · CNCF · 2 upvotes · 0 comments - [CNCF Debuts KubeCon \+ CloudNativeCon Japan 2026 Schedule](https://daily.dev/posts/cncf-debuts-kubecon-cloudnativecon-japan-2026-schedule-xp5pyudub) · CNCF · 1 upvotes · 0 comments --- Tags: [#cyber](https://daily.dev/tags/cyber), [#malware](https://daily.dev/tags/malware) [View this post on daily.dev](https://daily.dev/posts/canadian-authorities-arrest-hacker-linked-to-snowflake-data-breaches-weuhwo8vl) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Canadian Authorities Arrest Hacker Linked to Snowflake Data Breaches","url":"https://daily.dev/posts/canadian-authorities-arrest-hacker-linked-to-snowflake-data-breaches-weuhwo8vl","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/canadian-authorities-arrest-hacker-linked-to-snowflake-data-breaches-weuhwo8vl"},"datePublished":"2024-11-05T15:35:36.182Z","dateModified":"2024-11-06T03:32:06.566Z","description":"Canadian authorities have arrested Alexander Moucka for breaching hundreds of Snowflake accounts and stealing personal data.
