Sixteen Billion Reasons to Stop Reusing Passwords

-

Source: Mashable

Security researchers recently uncovered a massive archive of exposed credentials that includes over sixteen billion passwords [1]. This compilation is not the result of a single security breach. Instead, it brings together logs from years of malware infections that quietly harvested login data from millions of infected systems. The files were discovered on an open instance of a cloud hosting platform, making them briefly accessible to anyone who knew where to look.

The leak includes credentials linked to well-known platforms such as Google, Microsoft, and Netflix. However, these companies were not breached. Rather, the data comes from users who had stored their passwords in browsers or files that were compromised by infostealer malware [1].

What makes this leak especially dangerous is the potential for automated attacks. Cybercriminals can use the data in credential stuffing campaigns, trying known username and password combinations across countless websites. Since many people still reuse passwords across services, this method often succeeds [2].

To stay safe, it is important to use unique and complex passwords for every account. Multi-factor authentication adds another layer of protection. A password manager can help organize secure credentials without relying on memory or browser storage. Tools like “Have I Been Pwned” allow users to check if their information has been part of a known leak.

This latest discovery serves as a reminder that proactive security habits are the best defense against the growing threat of credential theft.

The Hidden Lag Killing Your SIEM Efficiency

-

  If your security tools feel slower than they should, you’re not imagining it. Many IT teams blame their sluggish SIEM performance on query complexity or alert volume. But sometimes the real issue is much simpler: oversized input files quietly dragging your system down. Think about the last time you had to sift through a bloated PDF or an unoptimised log dump. Every unnecessary megabyte adds strain. Every redundant line eats up cycles. Your SIEM doesn’t just react to threats—it processes all incoming data, relevant or not. When it starts lagging, detection gets delayed, triage slows, and in the high-stakes world of threat response, even seconds count. We often focus on analytics and rule tuning, but upstream efficiency—what you feed into your system—deserves just as much attention. This article looks at how optimising your inputs unlocks downstream performance. Why Oversized Files Clog the Pipeline As data volumes grow, organisations face esca lating  data storage costs ,...

Critical Vulnerability in Veeam Backup & Replication Exposes Enterprises to Remote Code Execution By : Rei Ibraima A newly discovered critical vulnerability in Veeam’s Backup & Replication software, designated as CVE-2025-23120, poses a significant security risk to enterprise environments. The flaw allows authenticated domain users to execute arbitrary code remotely, potentially leading to full compromise of backup infrastructures. About CVE-2025-23120 The vulnerability arises from an insecure deserialization issue within Veeam Backup & Replication components—particularly in the .NET classes Veeam.Backup.EsxManager.xmlFrameworkDs and Veeam.Backup.Core.BackupSummary. Improper input validation in these components allows attackers to inject malicious serialized objects that are executed on the server side, resulting in Remote Code Execution (RCE). This issue affects systems where Veeam Backup & Replication is deployed in a domain-joined configuration, which—while common—is...

The China-linked cyber espionage group tracked as Lotus Panda has been attributed to a campaign that compromised multiple organizations in an unnamed Southeast Asian country between August 2024 and February 2025. "Targets included a government ministry, an air traffic control organization, a telecoms operator, and a construction company," the Symantec Threat Hunter Team said in a new report shared with The Hacker News. "The attacks involved the use of multiple new custom tools, including loaders, credential stealers, and a reverse SSH tool." The intrusion set is also said to have targeted a news agency located in another country in Southeast Asia and an air freight organization located in another neighboring country. The threat cluster, per Broadcom's cybersecurity division, is assessed to be a continuation of a campaign that was disclosed by the company in December 2024 as a high-profile organization in Southeast Asia since at least October 2023. ...
