Introduction
Microsoft, one of the biggest technology corporations in the world, currently boasts over 1B users across their variety of gadgets, services and applications.
They have also been the subject of a massive distributed denial-of-service attack which rendered a millions of fraudulent accounts and compromised the security of Microsoft as well as its legitimate users.
What happened? Who’s behind it all? How many people were affected? What data was compromised, and how much?!?!
What Happened to Microsoft?
A cyber-threat group originating from Vietnam has been identified as the perpetrator of this attack. Known as Storm-1152, this threat group has reportedly operated for several years before Microsoft announced their shutdown on 13 December 2023.
They began by breaching through Microsoft’s CAPTCHA and multi-factor authentication tools to acquire fake email accounts, which they then sold to other cybercriminals via the dark web. These recipients could use the account as a gateway to phishing, identity theft and other scams on users who assume these messages are coming from legitimate Microsoft users. Even if they don’t know the recipient personally, the use of the same secure email platform could garner some trust and cause the targets to respond.
Throughout their years of operation, Storm-1152 managed to create and sell an estimated 750 million fraudulent Microsoft accounts, thereby generating millions in illegal revenue and compromising the security of millions of real users—as well as other platforms connected via Microsoft’s Single-Sign On.
These accounts were sold for various purposes, including bypassing security measures like identity verification; enabling spam and phishing campaigns; and facilitating ransomware, data theft and other extortion schemes.
Impact on Users and Victims
In December 2023, Microsoft obtained a court order to seize Storm-1152’s infrastructure, effectively shutting down their operations. Then to be transparent and honest with their userbase, Microsoft publicly announced the takedown and shared details about Storm-1152’s activities to raise awareness.
The fraudulent accounts sold by Storm-1152 may have contained personal information like usernames, passwords, email addresses and even payment details. Victims whose accounts were compromised may have been bombarded with spam emails or malware, which as we know can lead to financial losses, data loss, and even system damage. Meanwhile, stolen personal information can be used to launch phishing attacks, steal identities, and commit fraud.
Any data breach can have long-term negative effects that we must be prepared to face and respond to at any time. This lingering attack on Microsoft proves that even giants in their respective industries aren’t immune from cybercriminal crosshairs.
Conclusion
The distributed denial-of-service attack carried out by Storm-1152 was a long and complex threat that compromised systems and put fraudulent accounts into millions of cybercriminals’ hands. Although they have exposed and shut down the threat actors responsible for this massive breach, it stands as a testament to what cybercriminals are capable of and how far the consequences can reach.
If your personal information is compromised in a cyberattack, whether it resembles the DDOS threat to Microsoft or something completely different, it’s important to have security services that can rectify vulnerabilities and re-secure your information. Change account logins, and use Dark Web Monitoring services like ours to receive immediate notifications when your personal data ends up on the dark web.
A safer digital world starts with honesty, vigilance and education!
