Russian SVR-Linked APT29 Targets JetBrains TeamCity Servers in Ongoing Attacks

Threat actors affiliated with the Russian Foreign Intelligence Services (SVR) have specific unpatched JetBrains TeamCity servers in prevalent attacks given that September 2023.

The exercise has been tied to a nation-condition team regarded as APT29, which is also tracked as BlueBravo, Cloaked Ursa, Cozy Bear, Midnight Blizzard (previously Nobelium), and The Dukes. It really is notable for the offer chain attack concentrating on SolarWinds and its prospects in 2020.

“The SVR has, on the other hand, been noticed utilizing the original obtain gleaned by exploiting the TeamCity CVE to escalate its privileges, go laterally, deploy additional backdoors, and consider other techniques to assure persistent and prolonged-term access to the compromised network environments,” cybersecurity companies from Poland, the U.K., and the U.S. stated.

The vulnerability in dilemma is CVE-2023-42793 (CVSS rating: 9.8), a critical security flaw that could be weaponized by unauthenticated attackers to achieve remote code execution on affected programs. It has due to the fact come under energetic exploitation by hacking crews, including individuals affiliated with North Korea, for malware shipping and delivery.

“The TeamCity exploitation normally resulted in code execution with superior privileges granting the SVR an advantageous foothold in the network environment,” the organizations observed.

“If compromised, accessibility to a TeamCity server would supply destructive actors with accessibility to that computer software developer’s source code, signing certificates, and the skill to subvert computer software compilation and deployment procedures — entry a malicious actor could further use to carry out offer chain functions.”

A profitable first accessibility is ordinarily adopted by reconnaissance, privilege escalation, lateral motion, and details exfiltration, though simultaneously taking techniques to evade detection working with an open-resource device called EDRSandBlast. The conclusion target of the attacks is to deploy a backdoor codenamed GraphicalProton that capabilities as a loader to deliver added payloads.

GraphicalProton, which is also identified as VaporRage, leverages OneDrive as a most important command-and-regulate (C2) conversation channel, with Dropbox dealt with as a fallback system. It has been set to use by the threat actor as element of an ongoing marketing campaign dubbed Diplomatic Orbiter that singles out diplomatic companies throughout the world.

As numerous as 100 gadgets located across the U.S., Europe, Asia, and Australia are mentioned to have been compromised as a outcome of what’s suspected to be opportunistic attacks.

Targets of the campaign incorporate an energy trade association companies that offer computer software for billing, medical devices, customer care, worker checking, economical administration, advertising and marketing, profits, and online video video games as well as hosting companies, tools producers, and tiny and big IT enterprises.

The disclosure arrives as Microsoft revealed Russia’s multi-pronged assault on Ukraine’s agriculture sector involving June by way of September 2023 to penetrate networks, exfiltrate knowledge, and deploy destructive malware these kinds of as SharpWipe (aka WalnutWipe).

The intrusions have been tied back again to two nation-point out groups codenamed Aqua Blizzard (formerly Actinium) and Seashell Blizzard (previously Iridium), respectively.

Seashell Blizzard has also been noticed getting benefit of pirated Microsoft Business software program harboring the DarkCrystalRAT (aka DCRat) backdoor to obtain initial access, subsequently employing it to download a 2nd-phase payload named Shadowlink that masquerades as Microsoft Defender but, in reality, installs a TOR support for surreptitious distant entry.

“Midnight Blizzard took a kitchen sink technique, utilizing password spray, qualifications acquired from third-parties, believable social engineering strategies by means of Groups, and abuse of cloud companies to infiltrate cloud environments,” the tech big claimed.

Microsoft further more highlighted a Russia-affiliated impact actor it calls Storm-1099 (aka Doppelganger) for carrying out complex pro-Russia impact functions targeting global supporters of Ukraine given that the spring of 2022.

Other influence endeavours comprise spoofing mainstream media and deceptively editing movie star films shared on Cameo to propagate anti-Ukraine online video content and malign President Volodymyr Zelensky by falsely professing he experienced from compound abuse issues, underscoring continued endeavours to warp world-wide perceptions of the war.

“This marketing campaign marks a novel strategy by pro-Russia actors seeking to even further the narrative in the on line facts space,” Microsoft said. “Russian cyber and impact operators have demonstrated adaptability all through the war on Ukraine.”
