What Led To This Attack?

Nobelium, also known as APT29 or Cozy Bear, is a sophisticated hacking group with a history of attempting to breach the systems of U.S. allies and the Department of Defense.

According to the Microsoft Security Response Center, the hacker used a password attack in late November 2023, compromising a legacy non-production test tenant account to gain entry. Subsequently, they utilized the account’s permissions to access a limited number of Microsoft corporate email accounts.

The group primarily targeted email accounts for self-information, but the extent of stolen emails and documents remains unclear. The company only discovered the attack on January 12th, and the duration of the attackers’ access to its systems has not been disclosed.

Microsoft reiterates that the attack did not exploit any vulnerabilities in its products or services. There is no evidence indicating the threat actor had access to customer environments, production systems, source code, or AI systems.

When Did This Hacking Occur?

The recent attack occurred shortly after Microsoft unveiled plans to update its software security. The security update was due to increasing Azure cloud attacks.

While there were minimal customer complaints about the incident, it adds to a series of cybersecurity challenges for the company. Microsoft faced the SolarWinds attack three years ago, followed by the compromise of 30,000 organizations’ email servers in 2021 due to a Microsoft Exchange Server flaw. Additionally, Chinese hackers breached U.S. government emails via a Microsoft cloud exploit last year.

It’s also important to remember that Nobelium, identified as part of the Russian foreign intelligence service SVR, orchestrated one of the most significant breaches in U.S. history through the SolarWinds attack. This involved adding malicious code to updates for SolarWinds’ Orion software, affecting several U.S. government agencies, with Microsoft itself entangled in the aftermath.

What Measures is Microsoft Taking Against This?

While Microsoft has not identified signs of Nobelium accessing customer data, production systems, or proprietary source code, the disclosure follows new U.S. requirements for reporting cybersecurity incidents.

A Microsoft spokesperson clarified that, despite not perceiving a material impact, the company aims to uphold the spirit of the rules.

In response to the recent incidents, Microsoft is undergoing a substantial shift in how it designs, builds, tests, and operates its software and services. This marks the most significant change to its security approach since introducing the Security Development Lifecycle (SDL) in 2004.
