MGM Resorts, the owner of several casinos and resorts around the world, continues to navigate a widespread outage after a cyberattack on Sunday forced it to shut down systems across dozens of its hotels. While the hotel chain claims it is able to keep operating as usual, users report that its systems are not operational. The hacker group Scattered Spider, well known for using social manipulation and cyber loopholes, has now claimed responsibility.
The cyberattack is hurting the company. MGM shares have dropped 6% since Monday. The company filed a report with the Securities and Exchange Commission on Wednesday saying that the attack represented a material risk to the company. The major credit rating agency Moody's also warned that the attack is highlighting"key risks" within MGM Resorts.
The group alleges that it was able to able to access MGM Hotel's account through social engineering — it found a random employee's profile on LinkedIn and called the help desk to get access to the employee's account.
