Rogue service accounts create hidden risk because they often keep privileged access long after the project, integration, or person that justified them is gone. For banks, credit unions, and other regulated organizations, they are one of the most overlooked risks we find when we assess a new client environment. <\/p>\n\n\n\n
Broader industry research supports that concern. Research from Silverfort<\/a>, conducted with Osterman Research, found only 5.7% of organizations said they could accurately inventory all non-human identities in their environment, including service accounts, API keys, tokens, and certificates. The same research found that roughly 40% of cloud non-human identities have no identified owner. \u00a0<\/strong><\/p>\n\n\n\n In practical terms, many organizations rely on accounts that hold standing, privileged access to critical systems without a clear owner, purpose, or review process. <\/p>\n\n\n\n A service account is an account used by an application, system, or automated process instead of a person. It allows software to sign in, connect to other systems, and complete tasks without anyone at a keyboard. <\/p>\n\n\n\n Common examples at a financial institution include a reporting script that pulls data from the core system overnight, a vendor integration that connects digital banking or loan origination software to your network, backup software, and scheduled maintenance tasks. Cloud app registrations, API keys, and tokens serve the same purpose in cloud environments. Security teams often group all of these under the broader term non-human identities.\u00a0<\/strong><\/p>\n\n\n\n Financial institutions depend on a long list of vendor connections and automated processes, and each one typically needs its own account to run. Many of these accounts receive broad permissions during setup so an integration works on the first try. Those permissions are rarely revisited once the system is live. <\/p>\n\n\n\n Service accounts also tend to fall outside the controls built for people. They usually cannot use multi-factor authentication, their passwords are often set to never expire, and they are commonly left out of the periodic user access reviews that examiners expect institutions to perform. The result is a group of accounts with some of the broadest access in the environment and some of the least oversight. <\/p>\n\n\n\n We see the same pattern repeatedly. A service account is created for a specific project, vendor integration, or reporting script. The project ends, the vendor relationship changes, or the person who set it up moves on, and the account stays active with its original permissions intact. <\/p>\n\n\n\n Over time, nobody owns it, nobody reviews it, and nobody notices when its behavior changes. Most institutions have a defined offboarding process for employees. Far fewer have one for the accounts an employee created or a former vendor relied on. <\/p>\n\n\n\n An unmanaged service account gives an attacker three advantages: no human owner watching it, no regular login pattern that makes unusual activity easy to spot, and often more access than anyone remembers granting.<\/strong><\/p>\n\n\n\n These accounts are also a common path during penetration testing.<\/a> In Windows environments, a technique called Kerberoasting<\/strong> lets any signed-in user request credentials tied to certain service accounts and attempt to crack the password offline. Accounts with old or weak passwords are the easiest targets. When one of those accounts carries administrative rights, a tester can move from a standard user account to broad network access in a short time.\u00a0<\/p>\n\n\n\n Managing service accounts well comes down to visibility, ownership, and routine review. These five steps give most institutions a practical starting point. <\/p>\n\n\n\n Visibility is the foundation. You cannot secure, monitor, or retire what you do not know exists. <\/p>\n\n\n\n If you are not confident you could list every service account in your environment today, including who owns it and why it still exists, it is worth a closer look. Service account visibility is one of the first gaps CyberAssurance looks for during our assessments and penetration tests, and our team can help you<\/a> find and address what may be hiding in plain sight.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Rogue service accounts create hidden risk because they often keep privileged access long after the project, integration, or person that justified…<\/p>\n","protected":false},"author":8,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[70],"tags":[],"class_list":["post-7110","post","type-post","status-publish","format-standard","hentry","category-cybersecurity"],"_links":{"self":[{"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/posts\/7110","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/comments?post=7110"}],"version-history":[{"count":3,"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/posts\/7110\/revisions"}],"predecessor-version":[{"id":7120,"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/posts\/7110\/revisions\/7120"}],"wp:attachment":[{"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/media?parent=7110"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/categories?post=7110"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cyberassurancenow.com\/index.php\/wp-json\/wp\/v2\/tags?post=7110"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}What Is a Service Account? <\/strong><\/h2>\n\n\n\n

Five Steps to Bring Service Accounts Under Control <\/strong><\/h2>\n\n\n\n
\n
List every service account across Active Directory, cloud platforms, and key applications. Pay close attention to accounts with passwords set to never expire, accounts that have not signed in recently, and accounts with administrative rights. Document what each one does and which system depends on it. <\/li>\n\n\n\n
Each account should have a specific person accountable for it. When a spreadsheet lists only a department, questions about the account tend to go unanswered. <\/li>\n\n\n\n
Build a review or expiration date into the request process so every new account has a scheduled checkpoint from day one. Include service accounts in the same periodic access reviews you already perform for employees. <\/li>\n\n\n\n
Grant each account only the access its task requires. Use long, complex passwords stored in a password vault. In Windows environments, group Managed Service Accounts can rotate passwords automatically. <\/li>\n\n\n\n
Watch service accounts the same way you would watch a privileged user, and alert on sign-ins at unusual times or from unfamiliar systems. When a project ends or a vendor relationship changes, disable the account, confirm nothing breaks, and then remove it. <\/li>\n<\/ol>\n\n\n\nGet an Independent View of Your Service Accounts <\/strong><\/h2>\n\n\n\n
