'Scattered Spider' behind Marks & Spencer cyberattack: Who are they?
What's the story
UK retail giant Marks & Spencer (M&S) is facing a major cyberattack, carried out by hacking group Scattered Spider, BleepingComputer has reported.
Scattered Spider is notorious for leveraging social engineering attacks, phishing, multi-factor authentication (MFA) bombing, and SIM swapping to gain network access to large organizations.
Its latest attack has caused widespread disruptions, including problems with M&S's contactless payment system and online ordering.
Amid the fallout of the incident, around 200 warehouse employees have been asked to stay at home.
Process
How did the attack take place?
Reportedly, the cyberattack on M&S is a ransomware incident that has encrypted the company's servers.
The hackers are believed to have first infiltrated M&S's systems in February, when they allegedly stole the NTDS.dit file from the Windows domain.
The file is critical as it serves as the primary database for Active Directory Services running on a Windows domain controller, and holds password hashes for Windows accounts.
