As soon as they gained entry to the portal, Menelik informed BleepingComputer they’d created a program that generated 7-digit service tags and submitted them to the portal web page beginning in March to scrape the returned data.
Because the portal reportedly didn’t embody any charge limiting, the risk actor claims they may harvest the data of 49 million buyer data by producing 5,000 requests per minute for 3 weeks, with out Dell blocking the makes an attempt.

Later that 12 months, in December, risk actors exploited a Twitter API bug to hyperlink tens of millions of telephone numbers and e-mail addresses to Twitter accounts, which had been then offered on hacking boards.
Extra just lately, a Trello API flaw was exploited final 12 months to hyperlink an e-mail tackle to fifteen million accounts, which had been, as soon as once more, put up on the market on a hacking discussion board. The information was later shared with Have I Been Pwned to concern notifications to these uncovered in the breach.
Whereas all of those incidents concerned scraping of information, they had been allowed because of the ease of entry to APIs and the shortage of correct charge limiting for the variety of requests that may be made per second from the identical host.
