Cybersecurity researchers are warning of a new campaign that leverages cracked versions of software as a lure to distribute information stealers like Lumma and ACR Stealer. The AhnLab Security Intelligence Center (ASEC) said it has observed a spike in the distribution volume of ACR Stealer since January 2025. A notable aspect of the stealer malware is the use of a technique called dead drop resolver to extract the actual command-and-control (C2) server. This includes relying on legitimate services like Steam, Telegram's Telegraph, Google Forms, and Google Slides. "Threat actors enter the actual C2 domain in Base64 encoding on a specific page," ASEC said . "The malware accesses this page, parses the string, and obtains the actual C2 domain address to perform malicious behaviors." ACR Stealer, previously distributed via Hijack Loader malware, is capable of harvesting a wide range of information from compromised systems, including files, web browser data, ...

Welcome to your weekly roundup of cyber news, where every headline gives you a peek into the world of online battles. This week, we look at a huge crypto theft, reveal some sneaky AI scam tricks, and discuss big changes in data protection. Let these stories spark your interest and help you understand the changing threats in our digital world. ⚡ Threat of the Week Lazarus Group Linked to Record-Setting $1.5 Billion Crypto Theft — The North Korean Lazarus Group has been linked to a "sophisticated" attack that led to the theft of over $1.5 billion worth of cryptocurrency from one of Bybit's cold wallets, making it the largest ever single crypto heist in history. Bybit said it detected unauthorized activity within one of our Ethereum (ETH) Cold Wallets during a planned routine transfer process on February 21, 2025, at around 12:30 p.m. UTC. The incident makes it the biggest-ever cryptocurrency heist reported to date, dwarfing that of Ronin Network ($624 million), Poly N...

Ransomware doesn't hit all at once—it slowly floods your defenses in stages. Like a ship subsumed with water, the attack starts quietly, below the surface, with subtle warning signs that are easy to miss. By the time encryption starts, it's too late to stop the flood.  Each stage of a ransomware attack offers a small window to detect and stop the threat before it's too late. The problem is most organizations aren't monitoring for early warning signs - allowing attackers to quietly disable backups, escalate privileges, and evade detection until encryption locks everything down. By the time the ransomware note appears, your opportunities are gone.  Let's unpack the stages of a ransomware attack, how to stay resilient amidst constantly morphing indicators of compromise (IOCs), and why constant validation of your defense is a must to stay resilient. The Three Stages of a Ransomware Attack - and How to Detect It Ransomware attacks don't happen instantly. Attackers follow a st...

Google Cloud has announced quantum-safe digital signatures in Google Cloud Key Management Service ( Cloud KMS ) for software-based keys as a way to bulletproof encryption systems against the threat posed by cryptographically-relevant quantum computers. The feature, currently in preview, coexists with the National Institute of Standards and Technology's (NIST) post-quantum cryptography (PQC) standards, the final versions of which were formalized in August 2024. "Our Cloud KMS PQC roadmap includes support for the NIST post-quantum cryptography standards (FIPS 203, FIPS 204, FIPS 205, and future standards), in both software (Cloud KMS) and hardware (Cloud HSM)," the company's cloud division noted . "This can help customers perform quantum-safe key import and key exchange, encryption and decryption operations, and digital signature creation." The tech giant said its underlying software implementations of these standards – FIPS 203 (aka ML-KEM), FIPS 204 ...

Australia has become the latest country to ban the installation of security software from Russian company Kaspersky, citing national security concerns. "After considering threat and risk analysis, I have determined that the use of Kaspersky Lab, Inc. products and web services by Australian Government entities poses an unacceptable security risk to Australian Government, networks and data, arising from threats of foreign interference, espionage and sabotage," Stephanie Foster PSM, the Secretary of the Department of Home Affairs, said . "I have also considered the important need for a strong policy signal to critical infrastructure and other Australian governments regarding the unacceptable security risk associated with the use of Kaspersky Lab, Inc. products and web services." Foster further pointed out that entities are responsible for managing the risks arising from Kaspersky's extensive collection of user data and exposure of that data to extrajudicial di...

Cryptocurrency exchange Bybit on Friday revealed that a "sophisticated" attack led to the theft of over $1.5 billion worth of cryptocurrency from one of its Ethereum cold (offline) wallets, making it the largest ever single crypto heist in history. "The incident occurred when our ETH multisig cold wallet executed a transfer to our warm wallet. Unfortunately, this transaction was manipulated through a sophisticated attack that masked the signing interface, displaying the correct address while altering the underlying smart contract logic," Bybit said in a post on X. "As a result, the attacker was able to gain control of the affected ETH cold wallet and transfer its holdings to an unidentified address." In a separate statement posted on the social media platform, Bybit's CEO Ben Zhou emphasized that all other cold wallets are secure. The company further said it has reported the case to the appropriate authorities. While there is no official conf...

OpenAI on Friday revealed that it banned a set of accounts that used its ChatGPT tool to develop a suspected artificial intelligence (AI)-powered surveillance tool. The social media listening tool is said to likely originate from China and is powered by one of Meta's Llama models , with the accounts in question using the AI company's models to generate detailed descriptions and analyze documents for an apparatus capable of collecting real-time data and reports about anti-China protests in the West and sharing the insights with Chinese authorities. The campaign has been codenamed Peer Review owing to the "network's behavior in promoting and reviewing surveillance tooling," researchers Ben Nimmo, Albert Zhang, Matthew Richard, and Nathaniel Hartley noted, adding the tool is designed to ingest and analyze posts and comments from platforms such as X, Facebook, YouTube, Instagram, Telegram, and Reddit. In one instance flagged by the company, the actors used ChatG...

Apple is removing its Advanced Data Protection (ADP) feature for iCloud from the United Kingdom with immediate effect following government demands for backdoor access to encrypted user data. The development was first reported by Bloomberg. ADP for iCloud is an optional setting that ensures that users' trusted devices retain sole access to the encryption keys used to unlock data stored in its cloud. This includes iCloud Backup, Photos, Notes, Reminders, Safari Bookmarks, voice memos, and data associated with its own apps. "We are gravely disappointed that the protections provided by ADP will not be available to our customers in the U.K. given the continuing rise of data breaches and other threats to customer privacy," the company was quoted as saying to Bloomberg. "ADP protects iCloud data with end-to-end encryption, which means the data can only be decrypted by the user who owns it, and only on their trusted devices." Customers who are already using AD...

An analysis of a data leak from a Chinese cybersecurity company TopSec has revealed that it likely offers censorship-as-a-service solutions to prospective customers, including a state-owned enterprise in the country. Founded in 1995, TopSec ostensibly offers services such as Endpoint Detection and Response (EDR) and vulnerability scanning. But it's also providing "boutique" solutions in order to align with government initiatives and intelligence requirements, SentinelOne researchers Alex Delamotte and Aleksandar Milenkoski said in a report shared with The Hacker News. The data leak contains infrastructure details and work logs from employees, as well as references to web content monitoring services used to enforce censorship for public and private sector customers. It's believed that the company provided bespoke monitoring services to a state-owned enterprise hit by a corruption scandal, indicating that such platforms are being used to monitor and control public...
