The cyber activist group known as Anonymous has posted a series of e-mails obtained from a former Bank of America (BofA) employee.
The e-mails - dating from November 2010 - discuss deleting documents from loan files for a group of insured properties.
"The following GMAC DTN's (document tracking numbers) need to have the images removed from Tracksource/Rembrandt," wrote an operations team manager.
"I have spoken to my developer and she stated that we cannot remove the DTNs from Rembrandt, but she can remove the loan numbers, so the documents will not show as matched to those loans."
According to Anonymous, the documents relate to the issue of whether BofA and their subsidiary Balboa Insurance had improperly foreclosed on homes.
"The way the system is, it's made to cheat the average person," an Anonymous rep told the New York Times.
The above-mentioned e-mails also include correspondence between Anonymous and the former employee, who described the bank as a "cult" intent on destroying his career.
"I'm well known throughout Bank of America... They saw to that when they showed everyone my picture and labeled me as a terrorist."
However, a BofA spokesman told Reuters the documents were only "clerical [or] administrative" in nature and not related to foreclosures.
"We are confident that his extravagant assertions are untrue," the spokesman said.
