Microsoft revealed this week that a notorious Russia-linked hacking group had gained access to email accounts belonging to a number of the company’s top executives and leaders. The attack raises serious questions about data security at one of the world’s largest tech firms.
Hackers Gain Access Through Password Spraying
According to Microsoft, the breach was conducted by a group known as Nobelium, the same actor behind the devastating SolarWinds hack in 2020. The hackers gained access to Microsoft’s network through a technique called password spraying, in which commonly used passwords are tried across many accounts until valid credentials are discovered.
“We detected unusual activity with a small number of internal Microsoft accounts, and upon review, we discovered one account had been used to view source code in a number of source code repositories,” Microsoft’s Threat Intelligence Center said in a statement.
While the company said only a “very small percentage” of internal emails were compromised, the credentials accessed belonged to members of its senior leadership team, including those overseeing security initiatives and Microsoft’s legal department.
Sensitive Information at Risk
The breach is especially concerning given the sensitive nature of many Microsoft executives’ communications. Emails could have revealed information on unannounced products and services, confidential business plans and strategy, pending mergers and acquisitions, executive hires and departures, security audits, vulnerability assessments, and more.
“This attack is another example of how cyber espionage continues to grow as a lucrative business for criminals and needs to be countered globally through diplomacy and law enforcement,” said threat intelligence analyst Corin Imai.
In addition, the contents of employee emails often include sensitive personal information that could be used by hackers for identity theft, extortion, and other criminal purposes.
Russian Group Seeking Insider Information
Experts say the attack was likely an espionage operation aimed at gathering intelligence and insider knowledge rather than a destructive cyberattack.
“By targeting the legal department, the hackers were likely trying to find out what Microsoft knows about them and their past exploits,” said Dave White, cyber threat analyst.
Nobelium, which has links to Russia’s SVR foreign intelligence service, was responsible for the SolarWinds campaign that infected numerous US government agencies and Fortune 500 companies in 2020. US officials have called it one of the most damaging cyber attacks in history.
“This shows that Russian state-sponsored groups are still actively targeting major tech providers like Microsoft, viewing them as rich repositories of sensitive data,” said threat researcher Marina Krotofil.
Ongoing Cyberwar Between US and Russia
The Nobelium attack comes amid heightened tensions between Russia and Western nations over cyberspace activities. In recent years, cyberattacks from Russia have targeted critical infrastructure, government computer systems, and private companies across Europe and North America.
At the same time, Russia has accused Western governments of orchestrating high-profile cyberattacks against Russian organizations. Experts view this tit-for-tat dynamic as evidence of a growing undeclared cyberwar between Russia and Western powers playing out across digital domains.
“State-backed campaigns like this will likely increase in frequency and severity, especially with global powers investing heavily in offensive cyber capabilities,” warned Paulo Shakarian, cyber conflict scholar at Arizona State University.
Microsoft Bolstering Defenses in Wake of Breach
For its part, Microsoft said it has notified all impacted customers while working to understand the full extent of the breach. The company stated it has no reason to believe customer systems have been impacted.
Microsoft also said it is strengthening account security protocols and improving monitoring tools to detect unusual activity in light of the attack.
“Cybersecurity training and vigilance are vital for any company with sensitive information that could prove valuable to state-sponsored actors,” said cybersecurity consultant Leyla Bilge. “Firms need to utilize robust technical controls and be ever-vigilant against phishing, password attacks, and other common intrusion vectors.”
Going forward, Microsoft faces tough questions about how its security measures failed to stop Russian infiltrators from penetrating deep into its networks to steal executive emails. The coming weeks may reveal further details on exactly how hackers carried out this espionage operation and what they were after in breaching America’s most valuable company.
