Microsoft's Top Execs' Emails Breached in Sophisticated Russia-Linked APT Attack

Microsoft's Top Execs' Emails Breached in Sophisticated Russia-Linked APT Attack

Jan 20, 2024 Cyber Espionage / Emails Security
Microsoft on Friday revealed that it was the target of a nation-state attack on its corporate systems that resulted in the theft of emails and attachments from senior executives and other individuals in the company's cybersecurity and legal departments. The Windows maker attributed the attack to a Russian advanced persistent threat (APT) group it tracks as  Midnight Blizzard  (formerly Nobelium), which is also known as APT29, BlueBravo, Cloaked Ursa, Cozy Bear, and The Dukes. It further said that it immediately took steps to investigate, disrupt, and mitigate the malicious activity upon discovery on January 12, 2024. The campaign is estimated to have commenced in late November 2023. "The threat actor used a  password spray attack  to compromise a legacy non-production test tenant account and gain a foothold, and then used the account's permissions to access a very small percentage of Microsoft corporate email accounts, including members of our senior leadership team a

Microsoft Warns of Widescale Credential Stealing Attacks by Russian Hackers

Jun 26, 2023 Cyber Threat / Password Security
Microsoft has disclosed that it's detected a spike in credential-stealing attacks conducted by the Russian state-affiliated hacker group known as Midnight Blizzard. The intrusions, which make use of residential proxy services to obfuscate the source IP address of the attacks, target governments, IT service providers, NGOs, defense, and critical manufacturing sectors, the tech giant's threat intelligence team said. Midnight Blizzard, formerly known as Nobelium , is also tracked under the monikers APT29, Cozy Bear, Iron Hemlock, and The Dukes. The  group , which drew worldwide attention for the SolarWinds supply chain compromise in December 2020, has  continued  to rely on  unseen tooling  in its targeted attacks aimed at foreign ministries and diplomatic entities. It's a sign of how determined they are to keep their operations up and running despite being exposed, which makes them a particularly formidable actor in the espionage area. "These credential attacks us
Microsoft Uncovers New Post-Compromise Malware Used by Nobelium Hackers

Microsoft Uncovers New Post-Compromise Malware Used by Nobelium Hackers

Aug 25, 2022
The threat actor behind the SolarWinds supply chain attack has been linked to yet another "highly targeted" post-exploitation malware that could be used to maintain persistent access to compromised environments. Dubbed  MagicWeb  by Microsoft's threat intelligence teams, the development reiterates Nobelium's commitment to developing and maintaining purpose-built capabilities. Nobelium is the tech giant's moniker for a cluster of activities that came to light with the  sophisticated attack targeting SolarWinds  in December 2020, and which overlaps with the Russian nation-state hacking group widely known as  APT29 , Cozy Bear, or The Dukes. "Nobelium remains highly active, executing multiple campaigns in parallel targeting government organizations, non-governmental organizations (NGOs), intergovernmental organizations (IGOs), and think tanks across the US, Europe, and Central Asia," Microsoft  said . MagicWeb, which shares similarities with another t

Defending Your Commits From Known CVEs With GitGuardian SCA And Git Hooks

May 20, 2024Software Security / Vulnerability
All developers want to create secure and dependable software. They should feel proud to release their code with the full confidence they did not introduce any weaknesses or anti-patterns into their applications. Unfortunately, developers are not writing their own code for the most part these days. 96% of all software contains some open-source components, and open-source components make up between  70% and 90% of any given piece of modern software . Unfortunately for our security-minded developers, most modern vulnerabilities come from those software components.  As new vulnerabilities emerge and are publicly reported as  Common Vulnerabilities and Exposures  (CVEs), security teams have little choice but to ask the developer to refactor the code to include different versions of the dependencies. Nobody is happy in this situation, as it blocks new features and can be maddening to roll back component versions and hope that nothing breaks. Developers need a way to  quickly  determine if
Russian Hackers Targeting Diplomatic Entities in Europe, Americas, and Asia

Russian Hackers Targeting Diplomatic Entities in Europe, Americas, and Asia

May 02, 2022
A Russian state-sponsored threat actor has been observed targeting diplomatic and government entities as part of a series of phishing campaigns commencing on January 17, 2022. Threat intelligence and incident response firm Mandiant attributed the attacks to a hacking group tracked as APT29 (aka Cozy Bear), with some set of the activities associated with the crew assigned the moniker  Nobelium  (aka UNC2452/2652). "This latest wave of spear phishing showcases APT29's enduring interests in obtaining diplomatic and foreign policy information from governments around the world," Mandiant  said  in a report published last week. The initial access is said to have been aided through spear-phishing emails masquerading as administrative notices, using legitimate but compromised email addresses from other diplomatic entities. These emails contain an HTML dropper attachment called ROOTSAW (aka  EnvyScout ) that, when opened, triggers an infection sequence that delivers and exec

Nobelium, the threat actor attributed to the massive SolarWinds supply chain compromise, has been once again linked to a series of attacks targeting multiple cloud solution providers, services, and reseller companies, as the hacking group continues to refine and retool its tactics at an alarming pace in response to public disclosures. The intrusions, which are being tracked by Mandiant under two different activity clusters UNC3004 and UNC2652, are both associated with UNC2452, an  uncategorized threat group  that has since been tied to the Russian intelligence service. UNC2652, in particular, has been observed targeting diplomatic entities with phishing emails containing HTML attachments with malicious JavaScript, ultimately dropping a Cobalt Strike Beacon onto the infected devices. "In most instances, post compromise activity included theft of data relevant to Russian interests," Mandiant researchers Luke Jenkins, Sarah Hawley, Parnian Najafi, and Doug Bienstock  said  in

Microsoft Warns of Continued Supply-Chain Attacks by the Nobelium Hacker Group

Oct 25, 2021
Nobelium, the  threat actor  behind the SolarWinds compromise in December 2020, has been behind an ongoing wave of attacks that compromised 14 downstream customers of multiple cloud service providers (CSP), managed service providers (MSP), and other IT services organizations, illustrating the adversary's continuing interest in targeting the supply chain via the "compromise-one-to-compromise-many" approach. Microsoft, which disclosed details of the campaign on Monday, said it notified more than 140 resellers and technology service providers since May. Between July 1 and October 19, 2021, Nobelium is said to have singled out 609 customers, who were collectively attacked a grand total of 22,868 times. "This recent activity is another indicator that Russia is trying to gain long-term, systematic access to a variety of points in the technology supply chain and establish a mechanism for surveilling – now or in the future – targets of interest to the Russian government,
