ASOS breach update: Hackers stole customer details and shopping searches
ASOS says attackers stole customer identities and shopping searches after tricking an employee for login credentials.
ASOS confirmed attackers accessed customer data after an employee was tricked into providing login credentials. The BBC, citing a sample from the attackers, reported names, addresses, phone numbers, emails, dates of birth, customer numbers, and website search terms were taken via Simon AI, a Snowflake-based personalization platform. Snowflake said its platform was not compromised, and ASOS said payment cards and passwords were not accessed. Attackers reportedly demanded a ransom to delete the data and first notified customers through the ASOS app.
- Employee credentials were used to reach ASOS customer data on Simon AI.
- Exposed data includes names, contacts, birth dates, and website searches.
- ASOS says payment cards and customer passwords were not accessed.
- Attackers demanded a ransom and alerted customers through the ASOS app.
- Snowflake said it found no compromise of its platform.

The customer data stolen from global fashion retailer ASOS includes more than just names and contact details, raising questions about its early reassurances.
As we reported earlier this week, ASOS customers received a push notification through the ASOS app alleging that the company had been hacked.
ASOS has confirmed that attackers accessed customer information after tricking an employee into handing over login credentials. While the retailer says payment card information and customer passwords were not accessed, reporting by the BBC shows the stolen information includes more than the “basic personal information” initially mentioned by the company.
The stolen login details were used to access information on third-party platforms used by ASOS. The company says it locked down the affected platforms and launched an investigation with internal and external specialists. It also says it has strengthened its security controls.
What data was stolen?
In our initial coverage, we highlighted the potentially detailed customer profiles associated with ASOS’s marketing setup. The BBC’s findings now establish that at least some shopping-related information was taken.
According to the BBC, which received a sample from the attackers, the exposed data includes:
- Names and home addresses
- Phone numbers and email addresses
- Customer numbers and dates of birth
- Searches customers made on the ASOS website
- Details such as when a customer started using ASOS
The BBC reported search terms including “reclaimed vintage,” “glamorous wide fit,” and “Asos petite.” That makes this more than a stolen contact list. The information can also reveal customers’ shopping interests and their relationship with the retailer.
The attackers’ original notification named Snowflake, a data storage and analysis platform. They subsequently told the BBC that they accessed the information through Simon AI, a platform built on Snowflake that ASOS uses for customer personalization.
Snowflake said it had found no compromise of its platform. Using stolen credentials to access a customer’s account or a connected service does not necessarily mean the underlying platform was breached. The available reporting does not establish a vulnerability in Snowflake or Simon AI.
ASOS’s communication with customers
Customers first heard about the breach from the cybercriminals, rather than the retailer. The attackers’ decision to send a notification through the ASOS app may have made that unavoidable.
But the Independent reported that ASOS’s full statement followed roughly five hours of silence, leaving customers alarmed by the notification and waiting for an explanation.
Security expert Kevin Beaumont criticized the response:
“ASOS are experiencing the exact same PR gaffs as Co-op and M&S by not being honest with customers. If you’re dealing with Advanced Persistent Teenagers you need much better crisis plans.”
While the attackers are threatening to release the data, ASOS says its full investigation will continue over the coming weeks. It will contact customers directly where it believes further information, support, or action is required.
Reportedly, the group gave ASOS two weeks to make contact and said it wanted a ransom in exchange for deleting customer information. ASOS did not disclose whether it would pay.
How to stay safe
ASOS says its website and app remain safe to use, and that payment card information and customer passwords were not accessed. But the stolen details and shopping searches could help scammers make targeted phishing messages more convincing.
A message that knows your name, or what you searched for, isn’t proof it came from ASOS.
- Be wary of unexpected emails, texts, or calls about the breach, refunds, deliveries, or problems with your ASOS account.
- Don’t follow links in unexpected messages, and don’t follow the Telegram link in the attackers’ message or engage with them. Go directly to the ASOS website or app to check your account.
- Don’t share passwords, security codes, or payment details in response to an unsolicited message or call. ASOS says it will never ask you to do this.
