"20 bids on different auctions in 30 minutes!
Never experienced anything like this in my 17 years!”, one person wrote on social media.
And another victim that Aftonbladet spoke to had similar problems.
- I saw that I had bid 1,400 kroner for a pair of sweatpants, so I logged into my profile and saw that I had bid on 13 items, he told the newspaper.
Traders quickly responded with verification requirements
Not long after users discovered the fake bids, the problem was fixed.
And to prevent further infringements, Tradera has changed the rules temporarily.
- We have added that you have to verify yourself with a Bank ID to participate in a bidding process, says security manager Niclas Hjelm to SVT.
Verification requirements prevail before then, but then only for high-amount bidding or other specific cases.
The measure will apply until the security team is confident that the breach cannot be repeated.
Hjelm adds that all hacked accounts have been deactivated and incorrect bids have been removed.
- But everything is not clear until we have made contact with each user and can ensure that they are the right person who has access to their account, he says.
