Comcast says hackers stole data of close to 36 million Xfinity customers
Hackers exploited a known but unpatched flaw, allowing hackers access to the sensitive information of almost 36 million Comcast customers.
Comcast has confirmed that hackers exploiting a critical-rated security vulnerability accessed the sensitive information of almost 36 million Xfinity customers.
This vulnerability, known as “CitrixBleed,” is found in Citrix networking devices often used by big corporations and has been under mass-exploitation by hackers since late August. Citrix made patches available in early October, but many organizations did not patch in time. Hackers have used the CitrixBleed vulnerability to hack into big-name victims, including aerospace giant Boeing, the Industrial and Commercial Bank of China, and international law firm Allen & Overy.
Notice To Customers of Data Security Incident
December 18, 2023 04:30 PM Eastern Standard TimePHILADELPHIA--(BUSINESS WIRE)--Xfinity is providing notice of a recent data security incident. Starting today, customers are being notified through a variety of channels, including through the Xfinity website, email, and news media.
On October 10, 2023, Citrix announced a vulnerability in software used by Xfinity and thousands of other companies worldwide. Citrix issued additional mitigation guidance on October 23, 2023. Xfinity promptly patched and mitigated the Citrix vulnerability within its systems. However, during a routine cybersecurity exercise on October 25, Xfinity discovered suspicious activity and subsequently determined that between October 16 and October 19, 2023, there was unauthorized access to its internal systems that was concluded to be a result of this vulnerability.
Xfinity notified federal law enforcement and initiated an investigation into the nature and scope of the incident. On November 16, Xfinity determined that information was likely acquired. After additional review of the affected systems and data, Xfinity concluded on December 6, 2023, that the customer information in scope included usernames and hashed passwords; for some customers, other information may also have been included, such as names, contact information, last four digits of social security numbers, dates of birth and/or secret questions and answers. However, the data analysis is continuing.
Xfinity has required customers to reset their passwords to protect affected accounts. In addition, Xfinity strongly recommends that customers enable two-factor or multi-factor authentication to secure their Xfinity account, as many Xfinity customers already do. While Xfinity advises customers not to re-use passwords across multiple accounts, the company is recommending that customers change passwords for other accounts for which they use the same username and password or security question.
Customers with questions can contact Xfinity’s dedicated call center at 888-799-2560 toll-free 24 hours a day, seven days a week. More information is available on the Xfinity website at www.xfinity.com/dataincident.
Customers trust Xfinity to protect their information, and the company takes this responsibility seriously. Xfinity remains committed to continued investment in technology, protocols and experts dedicated to helping to protect its customers.
This is infuriating, at this point I get several notifications a year about someone hacking my data. But every time I dont have a choice but to keep give data to the same companies . fucking hell
Its a hell of a thing reading this and finding out this way. They knew in October. They knew more in November. They finally say something in December, but I have yet to receive any communication from them acknowledging the breach. Thanks Comcast. You somehow suck and blow at the same time.
the wait to disclose was probably on purpose. it will get a lot less media attention this time of year vs october.
I love that all of my data is "open source" due to all of the security breaches
You can use google to find your social security number if you ever forget.
We really are living in the future.
I was trying to check how many customers Comcast has and, from what I saw, 36 million is just about all of them.
Damn, companies were using Citrix because remote desktop companies were iffy and AWS/screenshare companies like zoom and TeamViewer weren't "enterprise-y" enough.
What a blow.
This is the best summary I could come up with:
Comcast has confirmed that hackers exploiting a critical-rated security vulnerability accessed the sensitive information of almost 36 million Xfinity customers.
This vulnerability, known as “CitrixBleed,” is found in Citrix networking devices often used by big corporations and has been under mass-exploitation by hackers since late August.
Hackers have used the CitrixBleed vulnerability to hack into big-name victims, including aerospace giant Boeing, the Industrial and Commercial Bank of China, and international law firm Allen & Overy.
Xfinity, Comcast’s cable television and internet division, became the latest CitrixBleed victim, the company confirmed in a notice to customers on Monday.
The notice doesn’t say how many Xfinity customers have been impacted, and Comcast spokesperson Joel Shadle declined to say when asked by TechCrunch.
In a filing with Maine’s attorney general, Comcast confirmed that almost 35.8 million customers are affected by the breach.
