This follows a separate breach last month in which the ransomware group ShinyHunters claimed to have stolen FBI employee records, including job titles tied to investigations of China and Russia, raising concerns that foreign intelligence agencies could exploit the stolen data to identify high-value personnel. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What personal information was exposed in the Pentagon's Defense Manpower Data Center breach? Stolen records included Social Security numbers, names, addresses, sex, race, and occupational specialty for 2.8 million living individuals, part of a notification sent to more than 2 million current and former military members. Hackers gained access to the Defense Manpower Data Center system starting in October, maintaining access for months before discovery. Occupational specialty data is considered especially sensitive since it could help foreign intelligence agencies identify high-value military personnel. _daily.dev surfaces breach reports like this for teams assessing exposure from large-scale personnel data leaks._ ### What data did ShinyHunters claim to steal from the FBI? The ransomware group ShinyHunters claimed to have hacked FBI systems and stolen records of thousands of current or former employees, including job titles related to investigating China or Russia. The group said it has no plans to release the data, though its promises carry little weight given its history of extortion, and an FBI official publicly called on group members to turn themselves in. _Security teams tracking ransomware group activity like ShinyHunters follow incident writeups on daily.dev._ ## Similar posts on daily.dev - [US government says it got hacked — again](https://daily.dev/posts/us-government-says-it-got-hacked-again-portisxb8) · TechCrunch · 0 upvotes · 0 comments - [Japan's Digital Agency says VPN flaw exposed 246,000 personnel records](https://daily.dev/posts/japan-s-digital-agency-says-vpn-flaw-exposed-246-000-personnel-records-xafiisunz) · BleepingComputer · 0 upvotes · 0 comments - [2.7 million hit in workplace benefits data breach exposing SSNs, dates of birth and health account data](https://daily.dev/posts/2-7-million-hit-in-workplace-benefits-data-breach-exposing-ssns-dates-of-birth-and-health-account-d-g44lfrkw5) · IT Security Guru · 0 upvotes · 0 comments --- Tags: [#ransomware](https://daily.dev/tags/ransomware), [#data-breach](https://daily.dev/tags/data-breach) [View this post on daily.dev](https://daily.dev/posts/hacks-of-2-federal-agencies-in-a-month-have-spilled-a-bonanza-of-sensitive-data-rcigd7xvl) ```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":"Hacks of 2 federal agencies in a month have spilled a bonanza of sensitive data","url":"https://daily.dev/posts/hacks-of-2-federal-agencies-in-a-month-have-spilled-a-bonanza-of-sensitive-data-rcigd7xvl","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/hacks-of-2-federal-agencies-in-a-month-have-spilled-a-bonanza-of-sensitive-data-rcigd7xvl"},"datePublished":"2026-10-01T21:24:12.405Z","dateModified":"2026-10-06T02:52:59.769Z","description":"The Pentagon is notifying over 2 million current and former military members that a monthslong breach of the Defense Manpower Data Center exposed personnel...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b55f1b1e016c18ade9e17599e78fefcc?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b55f1b1e016c18ade9e17599e78fefcc?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Ars Technica","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Ars Technica","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/80883e0e48a34b5ebcf93777016cb3fe","url":"https://daily.dev/sources/arstechnica"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/hacks-of-2-federal-agencies-in-a-month-have-spilled-a-bonanza-of-sensitive-data-rcigd7xvl","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ransomware,data-breach","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Ars Technica","item":"https://daily.dev/sources/arstechnica"},{"@type":"ListItem","position":3,"name":"Hacks of 2 federal agencies in a month have spilled a bonanza of sensitive data"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/hacks-of-2-federal-agencies-in-a-month-have-spilled-a-bonanza-of-sensitive-data-rcigd7xvl#faq","mainEntity":[{"@type":"Question","name":"What personal information was exposed in the Pentagon's Defense Manpower Data Center breach?","acceptedAnswer":{"@type":"Answer","text":"Stolen records included Social Security numbers, names, addresses, sex, race, and occupational specialty for 2.8 million living individuals, part of a notification sent to more than 2 million current and former military members.
