Hackers Creating Fraudulent Crypto Tokens as Part of 'Rug Pull' Scams
Jan 24, 2022
Misconfigurations in smart contracts are being exploited by scammers to create malicious cryptocurrency tokens with the goal of stealing funds from unsuspecting users. The instances of token fraud in the wild include hiding 99% fee functions and concealing backdoor routines, researchers from Check Point said in a report shared with The Hacker News. Smart contracts are  programs  stored on the blockchain that are automatically executed when predetermined conditions are met according to the terms of a contract or an agreement. They allow trusted transactions and agreements to be carried out between anonymous parties without the need for a central authority. By examining the  Solidity  source code used for implementing smart contracts, the Israeli cybersecurity company found instances of  hidden  and  hardcoded fees  that can't be changed, while allowing malicious actors to exert control over "who is allowed to sell." In another instance, a legitimate contract called

Malvertisers Exploited WebKit 0-Day to Redirect Browser Users to Scam Sites
Feb 17, 2021
A malvertising group known as "ScamClub" exploited a zero-day vulnerability in WebKit-based browsers to inject malicious payloads that redirected users to fraudulent websites gift card scams. The attacks, first spotted by ad security firm Confiant in late June 2020, leveraged a bug (CVE-2021–1801) that allowed malicious parties to bypass the iframe sandboxing policy in the browser engine that powers Safari and Google Chrome for iOS and run malicious code. Specifically, the technique exploited the manner how WebKit handles JavaScript event listeners , thus making it possible to break out of the sandbox associated with an ad's inline frame element despite the presence of "allow-top-navigation-by-user-activation" attribute that explicitly forbids any redirection unless the click event occurs inside the iframe. To test this hypothesis, the researchers set about creating a simple HTML file containing a cross-origin sandboxed iframe and a button outside it that

Probably not, as app developer Johnny Lin last week analyzed the Apple's App Store and discovered that most of the trending apps on the app store are completely fake and are earning their makers hundreds of thousands of dollars through in-app purchases and subscriptions. Scammers Use 'Search Ads' Platform to Boost App Ranking Shady developers are abusing Apple's relatively new and immature App Store Search Ads, which was launched at last year's Worldwide Developers Conference (WWDC), to promote their app in the store by using a few strategically chosen search ads and a bit of SEO. "They're taking advantage of the fact that there's no filtering or approval process for ads, and
