There was an update on the hacking attempts by hackers linked to Russian foreign intelligence on Friday. They used data stolen from corporate emails in January to gain access to Microsoft's systems again, which were used by the foreign intelligence services to gain access to the tech giant's products, which are widely used in the national security establishment in the United States. 

Analysts were alarmed by the disclosure as they expressed concerns about whether the U.S. government could use Microsoft's digital services and infrastructure safely. Microsoft is one of the world's largest software companies which provides systems and services to the government, including cloud computing. 

It has been alleged that the hackers have in recent weeks gained access to Microsoft's internal systems and source code repositories using information stolen from the company's corporate email system. The tech firm said that the hackers had used this information to access the company's corporate email systems. It is the nuts and bolts of a software program which make it work. 

Therefore, source code is of great importance to corporations - as well as spies trying to penetrate it. With access to the source code, hackers may be able to carry out follow-on attacks against other systems if they have access. During the first days of January, Microsoft announced that its cloud-based email system had been breached by the same hackers, days before another big tech company, Hewlett Packard Enterprise, announced that its cloud-based email system was breached. 

Although the full scope and purpose of the hacking activity is unclear, experts say the group responsible for the hack has a history of conducting extensive intelligence-gathering campaigns for the Kremlin. According to Redmond, which is examining the extent of the breach, the Russian state-sponsored threat actor may be trying to take advantage of the different types of secrets that it found in its investigation, including emails that were shared between Microsoft and its customers. 

Even though they have contacted the affected customers directly, the company didn't reveal what the secrets were nor what the extent of the compromise was. It is unclear what source code was accessed in this case. According to Microsoft, as well as stating that it has increased its security investments, the adversary ramped up its password spray attacks more than tenfold in February, in comparison to the "amount of activity" that was observed earlier in the year. 

Several analysts who track Midnight Blizzard report that they target governments, diplomatic agencies, non-governmental organizations, and other non-governmental organizations. Because of Microsoft's extensive research into Midnight Blizzard's operations, the company believes the hacker group might have targeted it in its January statement. 

Ever since at least 2021, when the group was found to have been behind a series of cyberattacks that compromised a wide range of U.S. government agencies, Microsoft's threat intelligence team has been conducting research on Nobleium and sharing it with the public. According to Microsoft, persistent attempts to breach the company are a sign that the threat actor has committed significant resources, coordination, and focus to the breach effort. 

As part of their espionage campaigns, Russian hackers have continued to hack into widely used tech companies in the years since the 2020 hack. US officials and private experts agree that this is indicative of their persistent, significant commitments to the breach. An official blog post that accompanied the SEC filing on Friday said that the hackers may have gathered an inventory of potential targets and are now planning to attack them, and may have enhanced their ability to do so by using the information they stole from Microsoft. 

Several high-profile cyberattacks have occurred against Microsoft due to its lax cybersecurity operations, including the compromise of Microsoft 365 (M365) cloud environment by Chinese threat actors Storm-0558, as well as a series of PrintNightmare vulnerabilities, ProxyShell bugs, two zero-day exchange server vulnerabilities known as ProxyNotShell that have been reported as well. 

Microsoft released the February Patch Tuesday update which addressed the admin-to-kernel exploit in the AppLocker driver that was disclosed by Avast six months after Microsoft accepted Avast's report about the exploit. The North Korean adversary Lazarus Group, which is known for exploiting the Windows kernel's read/write primitive to establish a read/write primitive on the operating system, used the vulnerability to install a rootkit on the system. The company replaced its long-time chief information security officer, Bret Arsenault, with Igor Tsyganskiy in December 2023 to alleviate security concerns.
