Indian Stock Broker Angel One Discloses Data Breach

Indian stock brokerage firm Angel One on Friday disclosed a data breach impacting client information stored in its Amazon Web Services (AWS) account.

The incident, the company said, was discovered after it received an email alert from a ‘dark web monitoring partner’ on February 27, regarding a ‘data leakage post’.

“After analyzing the post, it was ascertained that some of Angel One’s AWS resources were compromised,” the company said.

Angel One says it immediately changed the passwords for its AWS cloud and related applications, and that it retained external experts to investigate the incident, assess the scope of the data breach, and identify its root cause.

“We have verified that this breach does not have any impact on clients’ securities, funds and credentials; and all our client accounts remain secure,” the company said.

While the company has not shared details on how the data breach occurred, it appears that the attack was possible due to cybersecurity failures on Angel One’s part rather than a hack of AWS’s systems.

SecurityWeek has emailed AWS for a statement and will update this article if a reply arrives.

Following the data breach announcement, Angel One’s shares dropped over 11% in two days, hitting a 52-week low on Monday, March 3.
