Gumtree is the UK version of Craigslist. A few weeks ago, I listed a desk, a rug and a handbag there. I only ever checked my listings on my personal iPad and on my Macbook at home in my own password-protected Wifi. I also recently changed my Gumtree password, because I change all of them (eBay, Paypal, etc) bi-monthly. Today, I keep getting phone calls since the early morning of people asking for the Golf I listed. I'm like what the heck - I don't have a car, I cannot even drive!! I check my Gumtree account and among my active listings there is a listing for a black VW Golf - that I never wrote - because again, I don't have a car. I deleted it right away, which was stupid, because I should have at least screenshot it to get some clues to who this person is, but I just panicked and couldn't think beyond "OMG I WAS HACKED!!!111one". Now, after I had a cup of tea and changed my passwords again, I'm trying to wrap my head around three things: 1) Was this a genuine technical hiccup where someone's ad showed up on my account? Is that even likely? 2) If it wasn't and someone hacked into my account - then why? There is no way for them to gain something from me in such a "scam"? I mean, the potential customers are calling me because only my phone number shows up next to the listing, I tell them "nope, sorry, I don't have a car" ... no money ever gets transferred... I don't see how such a scam could possibly work for the scammer? 3) If someone hacked me? How? Did they only hack that Gumtree account? How? I never left it logged in on a public computer or public wifi. Or is this a much bigger issue of someone hacking into my computer? (which would explain the "how did they get on my Gumtree?", since my Gumtree password was saved in my Mac's keychain) How did they hack into my computer though? My Wifi is secure and I looked just now into my Router's menu to check what devices have all been connected to my Wifi in the past few months and they are all mine. This is just so weird, I don't get it. EDIT: I was just looking through yesterday's emails and lo and behold, there is the confirmation email for posting the car ad, that I never posted. ????
