Symantec is investigating an Indian hacking group's claims that it accessed source code used in the company's flagship Norton Antivirus program.
A spokesman for the company on Thursday said that one claim by the group was false, while another is still being investigated.
Meanwhile, the Indian group, which calls itself Lords of Dharmaraja, has threatened to publicly disclose the source code shortly.
On Wednesday, the group posted on Pastebin what it claimed was confidential documentation related to Norton AntiVirus source code. A review of the material showed what appears to be a description of an application programming interface (API) for Symantec's AV product.
The group also posted what it claimed was the complete source code tree file for Norton Antivirus. That document appears to have been taken down.
'Yama Tough,' the hacker who posted the documents, released at least two more on Google+ allegedly related to Symantec source code. One of the documents appears to be a detailed technical overview of Norton Anti-Virus, Quarantine Server Packaging API Specification, v1.0. The other document, from 2000, describes a Symantec Immune System Gateway Array Setup technology.
Comments posted by Yama Tough on Google+ and on Pastebin suggest that the Symantec information was accessed from Indian government servers.
"As of now we start sharing with all our brothers and followers information from the Indian Militaty (sic) Intelligence servers, so far we have discovered within the Indian Spy Programme (sic) source codes of a dozen software companies which have signed agreements with Indian TANCS programme (sic) and CBI," Yama Tough said in one comment.
Another comment suggests that the hacking group is waiting to set up mirror sites before releasing the Symantec source code. "We are working out mirrors as of now since we experience extreme pressure and censorship from US and India government agencies."
A Symantec spokesman today said that the hacking group has so far made two claims with regard to Symantec source code. One claim made yesterday has already been looked into, the spokesman said. "We investigated that and found that to not be true," the spokesman said. "It wasn't source code. It was a document from April 28, 1999 defining the Application Programming Interface (API) for the Definition Generation Service."
The document explains how the software is designed to work, but includes no actual source code, the spokesman said.
"However, a second claim has been made by the same group regarding additional source code and we're currently investigating that," he said. "For that one, we don't have any information to provide as of yet." the spokesman said.
Rob Rachwald, director of security strategy at security vendor Imperva said it is hard to know what to make of the hacking group's claims.
"We don't know how much of this is chest thumping" on the part of the hackers, Rachwald said. The source code tree file posted on Pastebin suggests the group has some potentially useful information related to Symantec's AV product, he said. "It is a good indicator, but not a perfect one."
Even if the group has managed to access Symantec's source code, it's unlikely to be very useful if the code is old, Rachwald said. "It might be useful in understanding what Symantec was trying to do" with its AV products, but little else, he said.
However, Symantec could face serious issues if the source code the hackers allege to have accessed is fresh, Rachwald added.
In that case, "Symantec will have to make some major changes" to its antivirus technology, Rachwald said. A mere patch would not be enough to address the issues created by a source code compromise.
"They would have to issue a whole body cast, not a patch," he said. "They will have to reissue the product in some format and that could be very problematic for them."
Competitors could also benefit from a Symantec source code leak because it would give them an unprecedented glimpse into how the software works, he said.
Rachwald said it's likely the Indian hackers obtained the source code from an Indian government server. Often, software companies such as Symantec are required to submit their source code to government bodies to prove they are not spying on the government, he said.
