Germany's Federal Criminal Police Office (aka Bundeskriminalamt or BKA) has seized the online infrastructure and shutdown linked to the eXch cryptocurrency exchange over allegations of money laundering and operating a criminal trading platform. The operation was carried out on April 30, 2025, authorities said, adding they also confiscated 8 terabytes worth of data and cryptocurrency assets worth €34 million ($38.25 million) in Bitcoin, Ether, Litecoin, and Dash. According to the BKA, eXch[.]cx, existed since 2014 and offered cryptocurrency swapping services, allowing its users to exchange digital assets. It was available both on the clearnet and the dark web. eXch "specifically advertised on platforms of the criminal underground economy (UE) that it did not implement any anti-money laundering measures," the BKA said in a statement. "Users were neither required to identify themselves to the service, nor was user data stored there. Crypto swapping via eXch was...

The North Korean threat actors behind the Contagious Interview campaign have been observed using updated versions of a cross-platform malware called OtterCookie with capabilities to steal credentials from web browsers and other files. NTT Security Holdings, which detailed the new findings, said the attackers have "actively and continuously" updated the malware, introducing versions v3 and v4 in February and April 2025, respectively. The Japanese cybersecurity company is tracking the cluster under the name WaterPlum , which is also known as CL-STA-0240, DeceptiveDevelopment, DEV#POPPER, Famous Chollima, PurpleBravo, and Tenacious Pungsan. OtterCookie was first documented by NTT last year after having observed it in attacks since September 2024. Delivered by means of a JavaScript payload via a malicious npm package, trojanized GitHub or Bitbucket repository, or a bogus videoconferencing app, it's designed to contact an external server to execute commands on compromis...

Cybersecurity researchers have flagged three malicious npm packages that are designed to target the Apple macOS version of Cursor, a popular artificial intelligence (AI)-powered source code editor. "Disguised as developer tools offering 'the cheapest Cursor API,' these packages steal user credentials, fetch an encrypted payload from threat actor-controlled infrastructure, overwrite Cursor's main.js file, and disable auto-updates to maintain persistence," Socket researcher Kirill Boychenko said . The packages in question are listed below - sw-cur (2,771 downloads) sw-cur1 (307 downloads), and aiide-cur (163 downloads) All three packages continue to be available for download from the npm registry. "Aiide-cur" was first published on February 14, 2025. It was uploaded by a user named "aiide." The npm library is described as a "command-line tool for configuring the macOS version of the Cursor editor." The other two packages, ...

Cybersecurity researchers have exposed what they say is an "industrial-scale, global cryptocurrency phishing operation" engineered to steal digital assets from cryptocurrency wallets for several years. The campaign has been codenamed FreeDrain by threat intelligence firms SentinelOne and Validin . "FreeDrain uses SEO manipulation, free-tier web services (like gitbook.io, webflow.io, and github.io), and layered redirection techniques to target cryptocurrency wallets," security researchers Kenneth Kinion, Sreekar Madabushi, and Tom Hegel said in a technical report shared with The Hacker News. "Victims search for wallet-related queries, click on high-ranking malicious results, land on lure pages, and are redirected to phishing pages that steal their seed phrases." The scale of the campaign is reflected in the fact that over 38,000 distinct FreeDrain sub-domains hosting lure pages have been identified. These pages are hosted on cloud infrastructure lik...

Cybersecurity researchers have lifted the lid on two threat actors that orchestrate investment scams through spoofed celebrity endorsements and conceal their activity through traffic distribution systems (TDSes). The activity clusters have been codenamed Reckless Rabbit and Ruthless Rabbit by DNS threat intelligence firm Infoblox. The attacks have been observed to lure victims with bogus platforms, including cryptocurrency exchanges, which are then advertised on social media platforms. An important aspect of these scams is the use of web forms to collect user data. "Reckless Rabbit creates ads on Facebook that lead to fake news articles featuring a celebrity endorsement for the investment platform," security researchers Darby Wise, Piotr Glaska, and Laura da Rocha said . "The article includes a link to the scam platform which contains an embedded web form persuading the user to enter their personal information to 'register' for the investment opportunity....

Cybersecurity researchers have discovered three malicious Go modules that include obfuscated code to fetch next-stage payloads that can irrevocably overwrite a Linux system's primary disk and render it unbootable. The names of the packages are listed below - github[.]com/truthfulpharm/prototransform github[.]com/blankloggia/go-mcp github[.]com/steelpoor/tlsproxy "Despite appearing legitimate, these modules contained highly obfuscated code designed to fetch and execute remote payloads," Socket researcher Kush Pandya said . The packages are designed to check if the operating system on which they are being run is Linux, and if so retrieve a next-stage payload from a remote server using wget. The payload is a destructive shell script that overwrites the entire primary disk (" /dev/sda ") with zeroes, effectively preventing the machine from booting up. "This destructive method ensures no data recovery tool or forensic process can restore the data, as...

Microsoft has revealed that a threat actor it tracks as Storm-1977 has conducted password spraying attacks against cloud tenants in the education sector over the past year. "The attack involves the use of AzureChecker.exe, a Command Line Interface (CLI) tool that is being used by a wide range of threat actors," the Microsoft Threat Intelligence team said in an analysis. The tech giant noted that it observed the binary to connect to an external server named "sac-auth.nodefunction[.]vip" to retrieve an AES-encrypted data that contains a list of password spray targets.  The tool also accepts as input a text file called "accounts.txt" that includes the username and password combinations to be used to carry out the password spray attack. "The threat actor then used the information from both files and posted the credentials to the target tenants for validation," Microsoft said. In one successful instance of account compromise observed by Redm...

North Korea-linked threat actors behind the Contagious Interview have set up front companies as a way to distribute malware during the fake hiring process. "In this new campaign, the threat actor group is using three front companies in the cryptocurrency consulting industry – BlockNovas LLC (blocknovas[.] com), Angeloper Agency (angeloper[.]com), and SoftGlide LLC (softglide[.]co) – to spread malware via 'job interview lures," Silent Push said in a deep-dive analysis. The activity, the cybersecurity company said, is being used to distribute three different known malware families, BeaverTail, InvisibleFerret , and OtterCookie . Contagious Interview is one of the several job-themed social engineering campaigns orchestrated by North Korea to entice targets into downloading cross-platform malware under the pretext of coding assignment or fixing an issue with their browser when turning on camera during a video assessment. The activity is tracked by the broader cybersecu...

Multiple threat activity clusters with ties to North Korea (aka Democratic People's Republic of Korea or DPRK) have been linked to attacks targeting organizations and individuals in the Web3 and cryptocurrency space. "The focus on Web3 and cryptocurrency appears to be primarily financially motivated due to the heavy sanctions that have been placed on North Korea," Google-owned Mandiant said in its M-Trends report for 2025 shared with The Hacker News. "These activities aim to generate financial gains, reportedly funding North Korea's weapons of mass destruction (WMD) program and other strategic assets." The cybersecurity firm said DPRK-nexus threat actors have developed custom tools written in a variety of languages such as Golang, C++, and Rust, and are capable of infecting Windows, Linux, and macOS operating systems. At least three threat activity clusters it tracks as UNC1069, UNC4899, and UNC5342 have been found to target members of the cryptocurren...

The Ripple cryptocurrency npm JavaScript library named xrpl.js has been compromised by unknown threat actors as part of a software supply chain attack designed to harvest and exfiltrate users' private keys. The malicious activity has been found to affect five different versions of the package: 4.2.1, 4.2.2, 4.2.3, 4.2.4, and 2.14.2. The issue has been addressed in versions 4.2.5 and 2.14.3. xrpl.js is a popular JavaScript API for interacting with the XRP Ledger blockchain, also called the Ripple Protocol, a cryptocurrency platform launched by Ripple Labs in 2012. The package has been downloaded over 2.9 million times to date, attracting more than 135,000 weekly downloads. "The official XPRL (Ripple) NPM package was compromised by sophisticated attackers who put in a backdoor to steal cryptocurrency private keys and gain access to cryptocurrency wallets," Aikido Security's Charlie Eriksen said . The malicious code changes have been found to be introduced by a...

Cybersecurity researchers have disclosed a malicious package uploaded to the Python Package Index (PyPI) repository that's designed to reroute trading orders placed on the MEXC cryptocurrency exchange to a malicious server and steal tokens. The package, ccxt-mexc-futures, purports to be an extension built on top of a popular Python library named ccxt (short for CryptoCurrency eXchange Trading), which is used to connect and trade with several cryptocurrency exchanges and facilitate payment processing services. The malicious package is no longer available on PyPI, but statistics on pepy.tech shows that it has been downloaded at least 1,065 times . "The authors of the malicious ccxt-mexc-futures package, claim in its README file that it extends the CCXT package to support 'futures' trade on MEXC," JFrog researcher Guy Korolevski said in a report shared with The Hacker News. However, a deeper examination of the library has revealed that it specifically overr...

The North Korea-linked threat actor assessed to be behind the massive Bybit hack in February 2025 has been linked to a malicious campaign that targets developers to deliver new stealer malware under the guise of a coding assignment. The activity has been attributed by Palo Alto Networks Unit 42 to a hacking group it tracks as Slow Pisces , which is also known as Jade Sleet, PUKCHONG, TraderTraitor, and UNC4899. "Slow Pisces engaged with cryptocurrency developers on LinkedIn, posing as potential employers and sending malware disguised as coding challenges," security researcher Prashil Pattni said . "These challenges require developers to run a compromised project, infecting their systems using malware we have named RN Loader and RN Stealer." Slow Pisces has a history of targeting developers, typically in the cryptocurrency sector, by approaching them on LinkedIn as part of a supposed job opportunity and enticing them into opening a PDF document that details the ...
