Their recent exploits include breaching the email accounts of HPE and Microsoft employees. Organizations must remain vigilant and proactive in their cybersecurity measures to defend against state-sponsored hacking groups. ## Content In recent news, the notorious Russian hacker group known as Cozy Bear has made headlines once again. This Kremlin-backed group, also referred to as APT29 and by various other aliases, has a long history of targeting governmental organizations and technology companies. Their latest exploits include breaching the email accounts of both HPE and Microsoft employees. The attack on HPE's cloud email environment was attributed to APT29, also known as BlueBravo, Cloaked Ursa, Cozy Bear, and The Dukes. The hackers were able to maintain undetected access to the mailbox data for a staggering six months before being discovered in December 2023. This incident is not the first time Cozy Bear has made waves in the cybersecurity world. They were also involved in the infamous SolarWinds supply chain attack, which caused significant damage to numerous organizations. This attack serves as a stark reminder of the relentless nature of state-sponsored hacking groups and their ability to infiltrate even the most secure systems. HPE, however, assures that the breach only impacted a small percentage of their mailboxes and did not have a significant impact on the company as a whole. They also stated that employing two-factor authentication could have potentially prevented the attack. It is crucial for organizations to remain vigilant and proactive in their cybersecurity measures. Cyber threats from state-sponsored actors such as Cozy Bear continue to evolve and pose a significant risk to both governmental and corporate entities. By staying informed and implementing robust security protocols, companies can better defend against these persistent adversaries. ## 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: [#security](https://daily.dev/tags/security), [#cyber](https://daily.dev/tags/cyber) [View this post on daily.dev](https://daily.dev/posts/russian-hackers-linked-to-kremlin-breach-hpe-s-corporate-mailboxes-eoifkw4kx) ```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":"Russian Hackers Linked to Kremlin Breach HPE's Corporate Mailboxes","url":"https://daily.dev/posts/russian-hackers-linked-to-kremlin-breach-hpe-s-corporate-mailboxes-eoifkw4kx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/russian-hackers-linked-to-kremlin-breach-hpe-s-corporate-mailboxes-eoifkw4kx"},"datePublished":"2024-01-25T06:31:39.740Z","dateModified":"2024-01-26T14:07:57.181Z","description":"The notorious Russian hacker group Cozy Bear, also known as APT29, has a long history of targeting governmental organizations and technology companies.
