NightEagle targets Russian companies

Kaspersky links NightEagle (APT-Q-95) attacks on Russian firms to compromised VPN credentials, a GhostContainer Exchange backdoor, RDP tunneling, BlueKeep exploitation, and DCSync.

Kaspersky's Global Emergency Response Team investigated NightEagle (APT-Q-95) incidents over the past year, finding the group—active since at least 2023 and formerly focused on Asia—now targeting Russian businesses. Attackers used compromised VPN credentials and deployed the GhostContainer .NET backdoor on Microsoft Exchange servers, built from Neo-reGeorg, a CVE-2020-0688 exploit, and ysoserial's GhostWebShell, injected in memory via VIEWSTATE manipulation with AMSI bypass. For lateral movement they combined Microsoft dev tunnels with rdp2tcp over RDP, exploited BlueKeep (CVE-2019-0708) to create local admin accounts, and performed DCSync replication against Active Directory.

CVE-2019-07089.8100%
Unauthenticated RCE in Microsoft Remote Desktop Services (BlueKeep)
CVE-2019-0708 is a use-after-free (CWE-416) vulnerability in Microsoft Remote Desktop Services, formerly Terminal Services, in which an unauthenticated attacker can connect to a target system over RDP and send specially crafted requests to trigger the flaw. Because the trigger requires no authentication, the flaw is wormable: a successful exploit grants remote code execution on the target host, potentially with elevated privileges, and could allow self-propagating attacks similar to WannaCry. Organizations running the affected Microsoft Remote Desktop Services, particularly legacy Windows releases still accepting inbound RDP connections, are in scope. Exploitation is confirmed in the wild: the flaw (nicknamed BlueKeep) is listed in CISA's KEV catalog (added 2021-11-03), CISA notes known ransomware use, and EPSS assigns it a 100% probability of exploitation within 30 days.

CVE-2020-06888.8100%
RCE in Microsoft Exchange Server from Shared Install-Time Validation Keys
CVE-2020-0688 is a remote code execution vulnerability in Microsoft Exchange Server caused by the validation key not being uniquely created at install time, leaving deployments with a predictable, shared key (CWE-287, improper authentication). A remote attacker who can reach an affected Exchange server and knows the common install-time key can supply maliciously crafted, cryptographically signed payloads that the server trusts, triggering code execution without needing per-server secrets. Successful exploitation gives the attacker code execution on the Exchange server, which can be used to access mail data, move laterally, and stage follow-on activity; CISA notes known use in ransomware campaigns. All organizations running the affected on-premises Microsoft Exchange Server are in scope per CISA's listing, though the affected version range is not specified in the source data. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2021-11-03 with known ransomware use, and EPSS rates 30-day exploitation probability at 100% (top percentile).
