Microsoft’s cyber threat detection team, MSTIC (Microsoft Threat Intelligence Center) has recently discovered a large-scale malicious email campaign.
MSTIC claimed that this large-scale malicious email campaign is operated by Nobelium it’s the same hacker group that is behind the SolarWinds attack, and linked to Russia.
Nobelium is the same hacker group that hacked several govt. agencies and large US companies through the SolarWinds program in December 2020, and for this attack the US accuses Russia.
“There are four tools representing a unique infection chain utilized by NOBELIUM: EnvyScout, BoomBox, NativeZone, and VaporRage. These tools have been observed being used in the wild as early as February 2021 attempting to gain a foothold on a variety of sensitive diplomatic and government entities”. Microsoft Said.
Targets
The vice president of Microsoft’s security and customer trust, Tom Burt indicated that this massive malicious email campaign is mainly directed at the:-
- Gov agencies of the US
- Think tanks
- Consultants
- NGOs
- Military
- IT service providers
- Healthcare
- Telecommunication providers
- Sporting organizations
- Anti-doping organizations
The hackers have targeted more than 3,000 email accounts in 150 organizations by using the phishing technique, and here the victims are dispersed in more than 24 countries, but, most of the victims are from the US.
These attacks are notable for three reasons
- First reason: When the SolarWinds attack is coupled with it, it becomes clear that in this event the primary goal of Nobelium is to infect the computer systems of trusted technology providers and gain access to them.
- Second reason: The activities of the Nobelium hacker group.
- Third reason: The nation-state cyberattacks are not slowing down.
This malicious email campaign is marked as “complex and advance” by Microsoft’s cyber threat detection team, MSTIC, but along with that badge, Microsoft also ensured that its cyber threat detection team is deeply investigating the scope and impact of this active campaign.
For each target, the hackers have used different attack patterns, infrastructure, and unique tools to remain undetected for a longer period of time.
After getting access to the Constant Contact account of USAID the Russian hacker group, Nobelium launched the attacks for this week, and for email marketing, they have used the Constant Contact service.
Through email marketing, the threat actors have distributed the genuine-looking phishing emails with a link to a malicious file utilized to spread a backdoor known as NativeZone.
With the help of this backdoor, NativeZone an attacker can easily steal essential data or even infect other computers on the same network. Moreover, the cybersecurity experts at MSTIC have concluded that Microsoft’s Windows Defender has the ability to stop such attacks.
