Cryptocurrency exchange Coinbase has disclosed that unknown cyber actors broke into its systems and stole account data for a small subset of its customers. "Criminals targeted our customer support agents overseas," the company said in a statement. "They used cash offers to convince a small group of insiders to copy data in our customer support tools for less than 1% of Coinbase monthly transacting users." The end goal of the campaign was to put together a list of customers who they contacted by masquerading as Coinbase and deceiving them into handing over their cryptocurrency assets. Coinbase said the threat actors then unsuccessfully attempted to extort the company for $20 million on May 11, 2025, by claiming to have information about certain customer accounts as well as internal documents. In a statement shared with Fortune, Coinbase said the compromised customer agents worked in India and have all been fired.  "No passwords, private keys, or funds w...

Imagine this: Your organization completed its annual penetration test in January, earning high marks for security compliance. In February, your development team deployed a routine software update. By April, attackers had already exploited a vulnerability introduced in that February update, gaining access to customer data weeks before being finally detected. This situation isn't theoretical: it plays out repeatedly as organizations realize that point-in-time compliance testing can’t protect against vulnerabilities introduced after the assessment. According to Verizons 2025 Data Breach Investigation Report , the exploitation of vulnerabilities rose 34% year-over-year. While compliance frameworks provide important security guidelines, companies need continuous security validation to identify and remediate new vulnerabilities before attackers can exploit them. Here’s what you need to know about pen testing to meet compliance standards — and why you should adopt continuous penetratio...

Google on Wednesday released updates to address four security issues in its Chrome web browser, including one for which it said there exists an exploit in the wild. The high-severity vulnerability, tracked as CVE-2025-4664 (CVSS score: 4.3), has been characterized as a case of insufficient policy enforcement in a component called Loader. "Insufficient policy enforcement in Loader in Google Chrome prior to 136.0.7103.113 allowed a remote attacker to leak cross-origin data via a crafted HTML page," according to a description of the flaw. The tech giant credited security researcher Vsevolod Kokorin (@slonser_) with detailing the flaw in X on May 5, 2025, adding it's aware "an exploit for CVE-2025-4664 exists in the wild." "Unlike other browsers, Chrome resolves the Link header on sub-resource requests," Kokorin said in a series of posts on X earlier this month. "The issue is that the Link header can set a referrer-policy. We can specify uns...

Ransomware has evolved into a deceptive, highly coordinated and dangerously sophisticated threat capable of crippling organizations of any size. Cybercriminals now exploit even legitimate IT tools to infiltrate networks and launch ransomware attacks. In a chilling example, Microsoft recently disclosed how threat actors misused its Quick Assist remote assistance tool to deploy the destructive Black Basta ransomware strain. And what’s worse? Innovations like Ransomware-as-a-Service (RaaS) are lowering the bar for entry, making ransomware attacks more frequent and far-reaching than ever before. According to Cybersecurity Ventures , by 2031, a new ransomware attack is expected every 2 seconds, with projected damages hitting an astronomical $275 billion annually. No organization is immune to ransomware, and building a strong recovery strategy is equally, if not even more, important than attempting to prevent all attacks in the first place. A solid business continuity and disaster re...

A Russia-linked threat actor has been attributed to a cyber espionage operation targeting webmail servers such as Roundcube, Horde, MDaemon, and Zimbra via cross-site scripting (XSS) vulnerabilities, including a then-zero-day in MDaemon, according to new findings from ESET. The activity, which commenced in 2023, has been codenamed Operation RoundPress by the Slovak cybersecurity company. It has been attributed with medium confidence to the Russian state-sponsored hacking group tracked as APT28, which is also referred to as BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard, FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422. "The ultimate goal of this operation is to steal confidential data from specific email accounts," ESET researcher Matthieu Faou said in a report shared with The Hacker News. "Most victims are governmental entities and defense companies in Eastern Europe, although we have observed governments in Africa, Europe, and South ...
