Brad Arkin, Adobe’s chief security officer, announced in a blog post Thursday that a sophisticated cyber attack on the company’s network caused the source code for numerous programs to be illegally accessed by hackers, as well as the personal information of millions of Adobe users.
Founded in 1982, the Silicon Valley company is known for an array of products, including the PhotoShop editing software and the PDF, SWF and FLV file formats.
According to Arkin, Adobe believes the attackers pilfered customer names, encrypted credit and debit card numbers, expiration dates, and other information related to customer orders pertaining to roughly 2.9 million Adobe clients.
Arkin said the company does not believe the attackers accessed decrypted information, but stopped short of confirming that plain-text data wasn’t compromised.
“We’re working diligently internally, as well as with external partners and law enforcement, to address the incident,” he said.
He also stated that the theft of customer data and the source code for numerous Adobe products was likely related.
