Hunting query for the ConnectWise Cloud Backup (SkyKick) application credential abuse reported in October 2026. It returns three signals, sorted by a Priority column. First, sign-ins by the seven ConnectWise and SkyKick application IDs from a public IP address. ConnectWise states the Cloud Backup app normally signs in from Azure private IPv6 addresses. Second, service principals that sign in from a public IP address in a country not seen in their 14-day baseline. This signal evaluates apps with at least 20 prior sign-ins. Third, Entra audit events initiated by applications. These include an application adding itself or another non-user identity to a directory role, an application adding or changing credentials for the first time in the baseline window and any credential change by an application named ConnectWise or SkyKick. Role additions with an unidentified target appear with Review priority. Audit events initiated by applications carry no source IP, so the IP indicator applies to the sign-in signals only. Routine credential changes by Azure services can still appear with Review priority. The query follows the Microsoft Defender advanced hunting schemas and runs without errors in Advanced Hunting. The audit signal was exercised against live Entra audit events in a Microsoft 365 tenant. Indicator columns are short-lived and used for enrichment only.
Detects a PaperCut server Java process spawning a local account creation or local administrators group addition, followed closely by Active Directory domain or computer enumeration from the same host within a 30-minute window.

Detects the creation or renaming of the 'ESX Admins' Active Directory security group combined with the addition of members to it, which is often used for privilege escalation or persistence in VMware ESXi environments managed via Active Directory.
Detects a sequence of events where an account performs a device code flow sign-in, registers or joins a device, and accesses a high volume of files in SharePoint or OneDrive within a 24-hour window. This pattern is commonly associated with adversary techniques abusing device code flows for initial access and registering managed/compromised devices to access sensitive corporate data.
Detects a potential app-only tenant-takeover sequence associated with Storm-3119 (YAM Store), where a single service principal performs an administrative password reset, a license assignment, and a privileged role grant within a one-hour window.
Detects five or more Entra ID device registrations by a single account where device names match microsoft-* or WINDOWS-* patterns, occurring shortly after a device code flow sign-in by the same account. This behavior is indicative of device registration abuse or persistent access attempts.
Detects the removal of user accounts from a specific sensitive Microsoft Entra ID group, which may indicate unauthorized group membership changes or potential privilege escalation activities.
Detects a single application or service principal performing a password reset, a license assignment, and a privileged role grant within a one-hour window. This sequence matches Storm-3119 admin-panel abuse of a compromised tenant client secret through an app-only flow in Microsoft 365 or Entra ID.
Detects a Slack role change conferring administrative rights. A workspace admin can
read private content, export conversation history, add applications and change
retention — so this is a meaningful privilege grant in a system that holds a great
deal of candid organisational information.
Onboarding: SLACK is ingested via Slack native connector (Bloo extractor 833).

Detects a user being added to a role within ClearPass. Role membership determines
what the network will permit an identity to reach, so granting a privileged role is
a network-layer privilege escalation that leaves no trace on any endpoint.
Additions outside provisioning hours, or by an account that does not normally
administer ClearPass, are the ones worth pursuing.
Onboarding: ARUBA-CLEARPASS is ingested via Syslog (CEF) (Bloo extractor 261).

Detects a service principal adding itself or another principal to a directory role in Azure Active Directory, specifically highlighting known ConnectWise supply-chain related activity.
Detects a role change in Zendesk. An administrator can read every ticket, export
data, alter automations and add agents — and support platforms are a favoured
target for social engineering precisely because agents are trained to be helpful to
strangers.
Onboarding: ZENDESK is ingested via NXLog (Bloo extractor 831).

Detects a role being added in Centrify for Linux. Roles determine which servers an
identity can reach and what it may do there, so adding one is a durable grant of
access to Unix infrastructure that frequently sits outside the scope of Windows
centric monitoring.
Onboarding: CENTRIFY-AUDITTRAIL-LINUX is ingested via Syslog (KV) (Bloo extractor 822).

Detects a role change on the Mimecast platform. A gateway administrator can read
quarantined mail, release held messages and alter policy — so this grant provides
both access to content and the ability to control what the organisation receives.
Onboarding: MIMECAST is ingested via Syslog (KV) (Bloo extractor 161).

Detects a privilege change recorded by Centrify on a Linux server. Centrify brokers
privileged access to Unix estates, so it sees elevation decisions that native auditd
may record only partially — and in many estates it is the only consistent record
across heterogeneous Linux and AIX systems.

Detects a privilege change within an Atlassian site. Confluence and Jira hold
architecture documentation, runbooks, credentials pasted into tickets and project
plans — so a privilege escalation here is a documentation-estate compromise, which
typically precedes a far more targeted attack elsewhere.
Onboarding: ATLASSIAN is ingested via NXLog (Bloo extractor 832).

Detects deletion of a role in Centrify for Windows. Removing a role can strip access
from legitimate administrators during an incident, and it also erases the record of
who was entitled to what — which complicates reconstructing the access position
afterwards.

Detects an account joining the workspace. Slack Connect and guest access let outside
identities into an internal communication space, and an unexpected join is how an
attacker gains a listening position without touching the network perimeter at all.
Check the account type: a guest or external identity joining a channel carrying
operational or security discussion is worth immediate confirmation with the inviter.
Onboarding: SLACK is ingested via Slack native connector (Bloo extractor 833).

Detects an endpoint or identity moving from a guest role to a corporate one. Guest
networks are deliberately segregated; a transition to corporate access means either
a legitimate onboarding or an attacker who entered through the least-controlled door
and found a way inward.
Onboarding: CISCO-ISE is ingested via Syslog (KV) (Bloo extractor 196).
