In this system, the product information including product descriptions and comments is stored in the interplanetary file system (IPFS) and the corresponding address is returned, and the returned address and the reputation scores of users are stored on the blockchain. To address this issue, we propose a blockchain-based decentralized reputation system (BC-DRS) in the E-commerce environment, i.e., online shopping. However, in the existing E-commerce environments, the reputation scores of users (including sellers and buyers) are centrally computed and stored on a centralized cloud server, which might make errors or even engage in fraud and forgery. Above all else: don't panic, because this is how attackers can trick you into doing something you'll regret.With the rapid development of E-commerce, more and more people are used to shopping online, in which the reputation scores of sellers play an important role in helping consumers purchase satisfactory products. It may be a scam sample they've not seen before, and this can in turn help them to protect a wider userbase. If there's no sign of it, consider sending it along to them directly. If it's genuine, you should be able to address whatever issue you've been sent. Go to the sourceĪlways remember to navigate directly to the sender of supposed security alerts. Whatever they’re up to, they should be treated with the cold shoulder they so richly deserve. It’s also possible the dialogue will simply continue via mail. What is sent back may be a booby-trapped document of some kind, or perhaps phishing done through a form. "Report the user" is the most interesting one, pre-filling the subject line as “Send statement”. This phish follows the same path, opening one of two pre-filled response styles depending on which button you select. Anybody replying would likely receive additional requests for login details or much more besides. Instead, it popped open a pre-formatted mail in your client of choice for you to respond to the creators. That mail didn’t bother with phishing pages. You may remember the phish attempt claiming to have detected unusual sign-in activity from Russia. This one follows the same pattern as a mail we covered a little while ago. What happens when you click the button(s)? The expected process is to be whisked away to a phishing page and enter your details. The second one just says “Yes, me” instead of something more plausible such as “Yes, it’s me” or even just “It was me”. The first one says “Report the user” which makes sense. However, it goes a bit off the rails with the two clickable buttons presented. We are sending you this email to verify it's really you. Someone tried to Iog into Your Account, User lDĪ user just logged into your Facebook account from a new device Samsung S21. When that happens, we often see increasing amounts of typos or broken mail design. There’s a tendency with some phish attempts to overstuff the mail with all manner of nonsense to look more convincing. The mail itself combines a fairly clean design with minimal messaging. As for the panic aspect, the phishers have pinned the hopes of this attack onto the old faithful “Someone is trying to login as you, so you'd better do something about it ASAP” routine. The mail looks professional enough, and seeks to imitate what would be a fairly typical looking message from Facebook. The ruse is quite simple: The mail senders are relying on the recipient’s sense of panic to respond without thinking about it. Watch out for bogus Facebook phishing messages winging their way to your mailbox.
