hackers allegedly stole 'almost 1 petabyte of data' Dulling the competitive blade For the past year, ShinyHunters have been an incredibly active threat actor. Security researchers said the group often engages in vishing (voice phishing), calling employees at target companies and posing as IT security staff.

In these calls, they are asking for remote access to their targets devices,
in order to fix a problem or sort a 2FA issue.

After being granted the access, they often access different platforms such as Salesforce or Snowflake, through which they are able to exfiltrate sensitive data and then extort the victims for money. While neither side confirmed the nature of the data stolen, security researchers from Cybernews said the files were probably internal company data.

The hackers [...] could potentially reveal customer or employee information such as PII, the type of businesses that were set up with the platform, the researchers said in a press release shared with TechRadar Pro . The breach could expose internal company operations as well, which can reduce ZenBusinesss competitive advantage. Are you a pro? Subscribe to our
