An unknown threat actor has been linked to a massive scam campaign that exploited an email routing misconfiguration in email security vendor Proofpoint's defenses to send millions of messages spoofing various popular companies like Best Buy, IBM, Nike, and Walt Disney, among others. "These emails echoed from official Proofpoint email relays with authenticated SPF and DKIM signatures , thus bypassing major security protections — all to deceive recipients and steal funds and credit card details," Guardio Labs researcher Nati Tal said in a detailed report shared with The Hacker News. The cybersecurity company has given the campaign the name EchoSpoofing . The activity is believed to have commenced in January 2024, with the threat actor exploiting the loophole to send as many as three million emails per day on average, a number that hit a peak of 14 million in early June as Proofpoint began to enact countermeasures. "The most unique and powerful part of this domain ...

The threat actors behind the  BlackCat ransomware  have shut down their darknet website and likely pulled an exit scam after uploading a bogus law enforcement seizure banner. "ALPHV/BlackCat did not get seized. They are exit scamming their affiliates," security researcher Fabian Wosar  said . "It is blatantly obvious when you check the source code of the new takedown notice." "There is absolutely zero reason why law enforcement would just put a saved version of the takedown notice up during a seizure instead of the original takedown notice." The U.K.'s National Crime Agency (NCA)  told  Reuters that it had no connection to any disruptions to the BlackCat infrastructure. Recorded Future security researcher Dmitry Smilyanets  posted  screenshots on the social media platform X in which the BlackCat actors claimed that the "feds screwed us over" and that they intended to sell the ransomware's source code for $5 million. The disappearing...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

The Classiscam scam-as-a-service program has reaped the criminal actors $64.5 million in illicit earnings since its emergence in 2019. "Classiscam campaigns initially started out on classified sites, on which scammers placed fake advertisements and used social engineering techniques to convince users to pay for goods by transferring money to bank cards," Group-IB  said  in a new report. "Since then, Classiscam campaigns have become highly automated, and can be run on a host of other services, such as online marketplaces and carpooling sites." A majority of victims are based in Europe (62.2%), followed by the Middle East and Africa (18.2%), and the Asia-Pacific (13%). Germany, Poland, Spain, Italy, and Romania accounted for the highest number of fraudulent transactions registered in Classiscam chats.  First discovered in 2019, Classiscam is an  umbrella term  for an operation that encompasses 1,366 distinct groups on Telegram. The activities first targeted R...

A sophisticated scam-as-a-service operation dubbed Classiscam has now infiltrated into Singapore, more than 1.5 years after  expanding to Europe . "Scammers posing as legitimate buyers approach sellers with the request to purchase goods from their listings and the ultimate aim of stealing payment data," Group-IB  said  in a report shared with The Hacker News. The cybersecurity firm called the operators a "well-coordinated and technologically advanced scammer criminal network." Classiscam refers to a  Russia-based cybercrime operation  that was first recorded in summer 2019 but only came under spotlight a year later coinciding with a surge in activity owing to an increase in online shopping in the aftermath of COVID-19 outbreak. Called the  most widely used fraud scheme  during the pandemic, Classiscam targets people who use marketplaces and services relating to property rentals, hotel bookings, online bank transfers, online retail, ride-sharing, ...

A number of India-based call centers and their directors have been indicted for their alleged role in placing tens of millions of scam calls aimed at defrauding thousands of American consumers. The indictment charged Manu Chawla, Sushil Sachdeva, Nitin Kumar Wadwani, Swarndeep Singh, Dinesh Manohar Sachdev, Gaje Singh Rathore, Sanket Modi, Rajiv Solanki and their respective call centers for conspiring with previously indicted VoIP provider E Sampark and its director, Guarav Gupta, to forward the calls to U.S. citizens.

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 le...

Facebook on Tuesday revealed it filed two separate legal actions against perpetrators who abused its ad platform to run deceptive advertisements in violation of the company's  Terms  and  Advertising Policies .  "In the first case, the defendants are a California marketing company and its agents responsible for a  bait-and-switch  advertising scheme on Facebook," the social media giant's Director of Platform Enforcement and Litigation, Jessica Romero,  said . "In the second case, the defendants are a group of individuals located in Vietnam who got users to self-compromise their Facebook accounts and ran millions of dollars of unauthorized ads." As part of the fraudulent activity, the marketing company, N&J USA Incorporated, promoted the sale of merchandise such as clothing, watches, and toys through misleading ads that, when clicked, redirected users to other e-commerce websites to complete the purchase, only to either receive nothing or get d...

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...

In this year's annual event, Apple announced that the company had paid out $70 Billion to developers in the App Store's lifetime and that $21 Billion of the amount was paid in the last year alone. But has all this money gone to the legitimate app developers? 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 ...

The major tech companies including Google, Facebook, and Yahoo! have joined their hands to launch a new program meant to block fake web traffic by blacklisting flagged IP addresses. Today, majority of data center traffic is non-human or illegitimate, so to fight against this issue the Trustworthy Accountability Group (TAG) has announced a program that will tap into Google's internal data-center blacklist to filter bots. The new pilot program will reject traffic from web robots or bots by making use of a blacklist, cutting a significant portion of web traffic from within data centers, said Google Ad Manager Vegard Johnsen. Google or any other big tech firm maintains a Blacklist that lists suspicious IP addresses of computer systems in data centers that may be trying to trick the human into clicking on advertisements. Google's DoubleClick blacklist alone blocked some 8.9% of data-center traffic back in May. Facebook and Yahoo to Contribute Apart from Goo...
