Amazon.com Inc. reveals that unidentified hackers were able to siphon assets from merchant’s accounts for over six months just the last year from the MNC.

The company believes that it was hit by quite an extensive fraud attack, this serious  attack which occurred between May 2018 and October 2018, had the attackers break into around 100 seller accounts and channel money from either loans or sales into their own respective bank accounts, as indicated by a U.K. legal document.

A redacted filing has been made by Amazon's legal advisors from November which was now made public.

While the MNC was still "investigating the compromised accounts" and trusted that hackers figured out how to change subtleties of the accounts on the Seller Central Platform to their very own at Barclays Plc and Prepay Technologies Ltd., which is mostly claimed by MasterCard Inc., as indicated by the filing. Amazon found that the accounts were likely undermined by phishing strategies that fooled the sellers into surrendering the confidential login data.

Since the attorneys for Amazon have asked a London judge to favour pursuits of account statements at Barclays and Prepay, which "have become innocently mixed up in the wrongdoing," the case is progressively being featured as the one where the world's greatest online retail platform is being abused and how troublesome it is for Amazon to locate the real culprits.

While Barclays declined to remark explicitly on the case and delegates for Prepay didn't return emails looking for their comments for the same. Amazon expressed its requirement for the documents “to investigate the fraud, identify and pursue the wrongdoers, locate the whereabouts of misappropriated funds, bring the fraud to an end and deter future wrongdoing," the company's legal counsellors said in the court filing.

The first fraudulent transfer is said to have been occurred on May 16, as indicated by the filing and Amazon said Tuesday that it issued more than $1 billion in loans to merchants in 2018.

Regardless it's unclear how much the hackers stole.
