UnitedHealth stock dips today as BlackCat ransomware guilty pleas revive cyber overhang

UnitedHealth stock dips today as BlackCat ransomware guilty pleas revive cyber overhang

NEW YORK, December 31, 2025, 1:03 ET — Regular session. UnitedHealth Group Incorporated shares fell 0.4% to $330.86 on Wednesday, extending a muted year-end session as investors weighed fresh legal developments tied to the ALPHV “BlackCat” ransomware gang. The stock traded between $330.32 and $333.24. The timing matters for UnitedHealth, which is heading into 2026 with investors focused on whether the insurer can keep a lid on costs while it works through a stack of operational and regulatory issues. That scrutiny tends to show up in the group’s pricing power and its medical care ratio — the share of premium

MongoDB stock today: MDB slips as “MongoBleed” vulnerability and patch push stay in focus

MongoDB stock today: MDB slips as “MongoBleed” vulnerability and patch push stay in focus

NEW YORK, December 30, 2025, 15:47 ET — Regular session. MongoDB, Inc. shares were down about 0.3% at $422.06 in late-afternoon trade on Tuesday, after swinging between $421.85 and $428.22 as investors digested fresh security disclosures around the database maker’s software. The issue matters now because it affects core infrastructure. “MongoBleed” is tied to CVE-2025-14847 — a standard vulnerability identifier — and involves an “unauthenticated” attack path, meaning an attacker may not need a username or password to try to pull sensitive data from a vulnerable server. The U.S. National Vulnerability Database said the flaw was added on Dec. 29

Why Qualys stock is sliding today: QLYS lags cybersecurity peers in late-year trade

Why Qualys stock is sliding today: QLYS lags cybersecurity peers in late-year trade

NEW YORK, December 30, 2025, 15:41 ET — Regular session Qualys Inc shares fell 2.5% to $133.93 in afternoon trading on Tuesday, after dropping as much as 4.2% earlier in the session. The stock closed at $137.34 on Monday. The decline landed as U.S. equities stayed range-bound in holiday-thin conditions, with technology and financial shares among the drags. “It’s just a healthy rebalancing of allocations more so than an emotionally driven sell-off,” said Mark Hackett, chief market strategist at Nationwide. Reuters That matters for Qualys because lighter year-end liquidity can exaggerate moves in single names, especially in software stocks where

CrowdStrike stock slips as CEO George Kurtz gets new performance award tied to $20B ARR goal

NEW YORK, December 29, 2025, 9:42 PM ET — Market closed CrowdStrike Holdings (CRWD.O) disclosed a new performance-based equity award for Chief Executive George Kurtz that could deliver up to 600,000 shares if the stock outperforms most of the S&P 500 over the next three years, a filing showed. The cybersecurity firm said the award carries a 300,000-unit target and can pay out nothing if performance falls below a threshold tied to relative returns. CrowdStrike shares ended down 1.1% at $475.91. SEC+1 The filing lands as investors reassess how much upside is left in high-growth software names into 2026, with

MongoDB stock slides on “MongoBleed” security update as agencies warn of active exploitation

NEW YORK, December 29, 2025, 20:50 ET — Market closed MongoDB, Inc. (MDB) shares closed down 2.9% on Monday at $423.14 after the database company posted a security update on a vulnerability informally called “MongoBleed.” The stock traded between $420.90 and $435.00 during the session. FinancialContent+1 Why this matters now: MongoDB’s software sits at the center of many applications, so urgent patching can trigger emergency maintenance, downtime risk and tough questions from customers about data protection. For a company that sells both self-managed database software and Atlas, its managed cloud database service, trust and response time are part of the

MongoDB stock slides as “MongoBleed” exploitation warning puts database security in focus

NEW YORK, December 29, 2025, 15:18 ET — Regular session MongoDB Inc (MDB) shares were down about 2.2% at $426.35 in afternoon trading on Monday, after swinging between $421.11 and $435.80 earlier in the session. The decline put a spotlight on a cyber risk that can matter quickly for database providers: patching cadence. When a vulnerability can be exploited without a login, security teams often move to lock down internet exposure before they do anything else. That urgency can ripple into spending decisions. Enterprises running self-managed databases may delay rollouts or add controls, while vendors face questions about whether cloud-managed

NEW YORK, December 29, 2025, 13:49 ET — Regular session. CrowdStrike Holdings, Inc. shares fell about 1% on Monday, down $4.77 to $476.42 in afternoon trading. The move put the cybersecurity firm among the decliners as investors pared exposure to technology shares in the final trading week of 2025 after last week’s rally pushed U.S. indexes to record highs, a Reuters report showed. Reuters Trading is expected to stay thin in the holiday-affected week, with U.S. markets closed on Thursday for New Year’s Day.

Coinbase Data Breach Investigation Update: Former Support Agent Arrested in India, CEO Brian Armstrong Says

Coinbase Data Breach Investigation Update: Former Support Agent Arrested in India, CEO Brian Armstrong Says

A former Coinbase customer service agent has been arrested in India in what the company describes as the latest breakthrough tied to a major security incident that shook the U.S.-based crypto exchange earlier this year. Coinbase CEO Brian Armstrong confirmed the arrest publicly, thanking Hyderabad Police and reiterating what he called a “zero tolerance” stance for insider misconduct. Investing.com+2The Financial Express+2 The arrest is significant because the breach Coinbase disclosed in May 2025 wasn’t driven by a traditional “hack” of user wallets or private keys. Instead, Coinbase said cybercriminals bribed a small group of overseas support personnel to access sensitive
