2.76 mil. pieces of customers' info at Hollys leaked in cyberattack

Hollys said hackers stole 2.76 million pieces of customer information from its membership program in a cyberattack sometime between Sept. 3 and Oct. 7. The leaked information includes dates of birth, phone numbers, addresses and email addresses. Hollys said the data came from temporary files used in a past membership-service overhaul, not its active customer database, and that it is investigating the incident.

Hollys detected unauthorized access to its system on Oct. 7 after the breach occurred sometime between Sept. 3 and Oct. 7.

The company said the affected files contained customer dates of birth, phone numbers, addresses and email addresses.

Hollys operates about 530 outlets nationwide and is owned by KG Group.

Financial regulators said about 100,000 cases of personal information leakage were presumed to have occurred at 16 financial institutions in recent hacking attacks.

Customer information held by local coffee chain Hollys has reportedly been leaked via hacking of its memberships program, the franchise said Monday, the latest in a string of cyberattacks targeting local companies.

A total of 2.76 million pieces of personal information, including the customers' dates of birth, phone numbers, addresses and emails, was stolen by the hackers sometime between Sept. 3 and Oct. 7, when the company detected unauthorized access to its system, according to a notice posted on the company's website.

"We understand that the leaked data consists of temporary data files provided for a past membership service overhaul, not the data from the currently active customer database," the notice read, adding the company is still investigating the exact scope of the incident.

"We sincerely apologize for causing customer concern from this incident. We will make our utmost efforts to protect customer data and minimize damage from the breach," it added.

The cybersecurity violation at Hollys follows back-to-back leaks of customer data at local financial firms early this month. Around 100,000 cases of leaked personal information are presumed to have taken place at 16 financial institutions in a recent series of hacking attacks as of Friday, according to financial regulators.

Hollys currently has around 530 outlets across the country and is owned by KG Group, a local conglomerate whose business ranges from steelmaking to car manufacturing and logistics services.

Hollys表示，黑客在9月3日至10月7日期间发动网络攻击，从其会员系统中窃取了276万条客户信息。泄露的信息包括出生日期、电话号码、地址和电子邮件地址。Hollys称，这些数据来自之前会员服务升级时使用的临时文件，而非其活跃客户数据库，目前公司正在调查此事。

Hollys 于 10 月 7 日检测到其系统遭到未经授权的访问，而此次安全漏洞发生在 9 月 3 日至 10 月 7 日之间的某个时间。

该公司表示，受影响的文件包含客户的出生日期、电话号码、地址和电子邮件地址。

Hollys 在全国拥有约 530 家门店，隶属于 KG 集团。

金融监管机构表示，在最近的黑客攻击中，16 家金融机构估计发生了约 10 万起个人信息泄露事件。

当地连锁咖啡店 Hollys 周一表示，其会员系统遭到黑客攻击，导致顾客信息泄露。这是近期针对当地企业的一系列网络攻击中的最新一起。

根据该公司网站上发布的通知，黑客在 9 月 3 日至 10 月 7 日期间窃取了总计 276 万条个人信息，其中包括客户的出生日期、电话号码、地址和电子邮件。当时该公司检测到其系统遭到未经授权的访问。

“我们了解到，泄露的数据是过去会员服务改版时提供的临时数据文件，而不是当前活跃客户数据库中的数据，”通知中写道，并补充说，该公司仍在调查事件的确切范围。

“对于此次事件给客户带来的担忧，我们深表歉意。我们将尽一切努力保护客户数据，并将此次泄露事件造成的损失降至最低。”声明补充道。

霍利斯银行的网络安全漏洞事件发生之前，本月初当地多家金融机构已接连发生客户数据泄露事件。据金融监管机构称，截至上周五，在近期一系列黑客攻击中，约有16家金融机构的个人信息遭到泄露。

Hollys目前在全国拥有约530家门店，隶属于KG集团，这是一家本地企业集团，其业务范围涵盖钢铁制造、汽车制造和物流服务。
