Blockchain is best known for its use in cryptocurrencies like Bitcoin, but it also holds significant applications for online authentication. As businesses in varying sectors increasingly embrace blockchain-based security tools, could the technology one day replace passwords? How blockchain works  Blockchain is a secure way to maintain, encrypt, and exchange digital records of transactions. Its security benefits stem from its decentralized nature: this distributed ledger can be accessed by participants across various nodes , and is unalterable. All users retain control as a group, meaning no single person can change the ledger. How could this provide security benefits? One advantage is the ability to create a 'self-sovereign ID' that alters the way that a user identifies themselves online. Essentially, it creates a private ID for a user that they control, rather than relying on a centralized institution : they can logon to a particular website or service using their identity on...

Introduction Cyber threats targeting supply chains have become a growing concern for businesses across industries. As companies continue to expand their reliance on third-party vendors, cloud-based services, and global logistics networks, cybercriminals are exploiting vulnerabilities within these interconnected systems to launch attacks. By first infiltrating a third-party vendor with undetected security gaps, attackers can establish a foothold, leveraging these weaknesses to penetrate the primary business partners' network. From there, they move laterally through critical systems, ultimately gaining access to sensitive data, financial assets, intellectual property, or even operational controls. Recent high-profile breaches like the 2024 ransomware attack that hit Change Healthcare, one of the world's largest health payment processing companies, demonstrate how attackers disrupted supply chain operations stealing up to 6TB of millions of patients' protected health information (PHI)....

Intro: Why hack in when you can log in? SaaS applications are the backbone of modern organizations, powering productivity and operational efficiency. But every new app introduces critical security risks through app integrations and multiple users, creating easy access points for threat actors. As a result, SaaS breaches have increased, and according to a May 2024 XM Cyber report, identity and credential misconfigurations caused 80% of security exposures. Subtle signs of a compromise get lost in the noise, and then multi-stage attacks unfold undetected due to siloed solutions. Think of an account takeover in Entra ID, then privilege escalation in GitHub, along with data exfiltration from Slack. Each seems unrelated when viewed in isolation, but in a connected timeline of events, it's a dangerous breach. Wing Security's SaaS platform is a multi-layered solution that combines posture management with real-time identity threat detection and response. This allows organizations to get a ...

Cybersecurity researchers have discovered a new, sophisticated remote access trojan called ResolverRAT that has been observed in attacks targeting healthcare and pharmaceutical sectors. "The threat actor leverages fear-based lures delivered via phishing emails, designed to pressure recipients into clicking a malicious link," Morphisec Labs researcher Nadav Lorber said in a report shared with The Hacker News. "Once accessed, the link directs the user to download and open a file that triggers the ResolverRAT execution chain." The activity, observed as recently as March 10, 2025, shares infrastructure and delivery mechanism overlap with phishing campaigns that have distributed information stealer malware such as Lumma and Rhadamanthys, as documented by Cisco Talos and Check Point last year. A notable aspect of the campaign is the use of localized phishing lures, with the emails crafted in the languages predominantly spoken in the targeted countries. This includ...

Unpatched TP-Link Archer routers have become the target of a new botnet campaign dubbed Ballista, according to new findings from the Cato CTRL team. "The botnet exploits a remote code execution (RCE) vulnerability in TP-Link Archer routers (CVE-2023-1389) to spread itself automatically over the Internet," security researchers Ofek Vardi and Matan Mittelman said in a technical report shared with The Hacker News. CVE-2023-1389 is a high-severity security flaw impacting TP-Link Archer AX-21 routers that could lead to command injection, which could then pave the way for remote code execution. The earliest evidence of active exploitation of the flaw dates back to April 2023, with unidentified threat actors using it to drop Mirai botnet malware. Since then, it has also been abused to propagate other malware families like Condi and AndroxGh0st . Cato CTRL said it detected the Ballista campaign on January 10, 2025. The most recent exploitation attempt was recorded on Februa...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the Food and Drug Administration (FDA) have issued alerts about the presence of hidden functionality in Contec CMS8000 patient monitors and Epsimed MN-120 patient monitors. The vulnerability , tracked as CVE-2025-0626 , carries a CVSS v4 score of 7.7 on a scale of 10.0. The flaw, alongside two other issues, was reported to CISA by an anonymous external researcher. "The affected product sends out remote access requests to a hard-coded IP address, bypassing existing device network settings to do so," CISA said in an advisory. "This could serve as a backdoor and lead to a malicious actor being able to upload and overwrite files on the device." "The reverse backdoor provides automated connectivity to a hard-coded IP address from the Contec CMS8000 devices, allowing the device to download and execute unverified remote files. Publicly available records show that the IP address is not associa...

Ransomware attacks have reached an unprecedented scale in the healthcare sector, exposing vulnerabilities that put millions at risk. Recently, UnitedHealth revealed that 190 million Americans had their personal and healthcare data stolen during the Change Healthcare ransomware attack, a figure that nearly doubles the previously disclosed total.  This breach shows just how deeply ransomware can infiltrate critical systems, leaving patient trust and care hanging in the balance. One of the groups that targets this already fragile sector is the Interlock ransomware group. Known for their calculated and sophisticated attacks, they focus on hospitals, clinics, and other medical service providers. Interlock Ransomware Group: An Active Threat to Healthcare The Interlock ransomware group is a relatively recent but dangerous player in the world of cybercrime, known for employing double-extortion tactics.  This method involves encrypting a victim's data to disrupt operations and th...

Cybersecurity researchers are calling attention to a new malware campaign that leverages fake CAPTCHA verification checks to deliver the infamous Lumma information stealer. "The campaign is global, with Netskope Threat Labs tracking victims targeted in Argentina, Colombia, the United States, the Philippines, and other countries around the world," Leandro Fróes, senior threat research engineer at Netskope Threat Labs, said in a report shared with The Hacker News. "The campaign also spans multiple industries, including healthcare, banking, and marketing, with the telecom industry having the highest number of organizations targeted." The attack chain begins when a victim visits a compromised website, which directs them to a bogus CAPTCHA page that specifically instructs the site visitor to copy and paste a command into the Run prompt in Windows that uses the native mshta.exe binary to download and execute an HTA file from a remote server. It's worth noting...

The United States Department of Health and Human Services' (HHS) Office for Civil Rights (OCR) has proposed new cybersecurity requirements for healthcare organizations with an aim to safeguard patients' data against potential cyber attacks. The proposal, which seeks to modify the Health Insurance Portability and Accountability Act (HIPAA) of 1996, is part of a broader initiative to bolster the cybersecurity of critical infrastructure, the OCR said. The rule is designed to strengthen protections for electronic protected health information (ePHI) by updating the HIPAA Security Rule's standards to "better address ever-increasing cybersecurity threats to the healthcare sector." To that end, the proposal, among other things, requires organizations to conduct a review of the technology asset inventory and network map, identify potential vulnerabilities that could pose a threat to electronic information systems, and establish procedures to restore the loss of certa...

New research has uncovered more than 145,000 internet-exposed Industrial Control Systems (ICS) across 175 countries, with the U.S. alone accounting for over one-third of the total exposures. The analysis , which comes from attack surface management company Censys, found that 38% of the devices are located in North America, 35.4% in Europe, 22.9% in Asia, 1.7% in Oceania, 1.2% in South America, and 0.5% in Africa. The countries with the most ICS service exposures include the U.S. (more than 48,000), Turkey, South Korea, Italy, Canada, Spain, China, Germany, France, the U.K., Japan, Sweden, Taiwan, Poland, and Lithuania. The metrics are derived from the exposure of several commonly-used ICS protocols like Modbus, IEC 60870-5-104, CODESYS, OPC UA, and others. One important aspect that stands out is that the attack surfaces are regionally unique: Modbus, S7, and IEC 60870-5-104 are more widely observed in Europe, while Fox, BACnet, ATG, and C-more are more commonly found in North Ame...

Cybersecurity researchers have shed light on a Linux variant of a relatively new ransomware strain called Helldown, suggesting that the threat actors are broadening their attack focus. "Helldown deploys Windows ransomware derived from the LockBit 3.0 code," Sekoia said in a report shared with The Hacker News. "Given the recent development of ransomware targeting ESX, it appears that the group could be evolving its current operations to target virtualized infrastructures via VMware." Helldown was first publicly documented by Halcyon in mid-August 2024, describing it as an "aggressive ransomware group" that infiltrates target networks by exploiting security vulnerabilities. Some of the prominent sectors targeted by the cybercrime group include IT services, telecommunications, manufacturing, and healthcare. Like other ransomware crews, Helldown is known for leveraging data leak sites to pressure victims into paying ransoms by threatening to publish s...

Cybersecurity researchers have discovered an advanced version of the Qilin ransomware sporting increased sophistication and tactics to evade detection. The new variant is being tracked by cybersecurity firm Halcyon under the moniker Qilin.B. "Notably, Qilin.B now supports AES-256-CTR encryption for systems with AESNI capabilities, while still retaining Chacha20 for systems that lack this support," the Halcyon Research Team said in a report shared with The Hacker News. "Additionally, RSA-4096 with OAEP padding is used to safeguard encryption keys, making file decryption without the attacker's private key or captured seed values impossible." Qilin, also known as Agenda , first came to the attention of the cybersecurity community in July/August 2022, with initial versions written in Golang before switching to Rust. A May 2023 report from Group-IB revealed that the ransomware-as-a-service (RaaS) scheme allows its affiliates to anywhere between 80% to 85% of ...

Cybersecurity and intelligence agencies from Australia, Canada, and the U.S. have warned about a year-long campaign undertaken by Iranian cyber actors to infiltrate critical infrastructure organizations via brute-force attacks. "Since October 2023, Iranian actors have used brute force and password spraying to compromise user accounts and obtain access to organizations in the healthcare and public health (HPH), government, information technology, engineering, and energy sectors," the agencies said in a joint advisory. The attacks have targeted healthcare, government, information technology, engineering, and energy sectors, per the Australian Federal Police (AFP), the Australian Signals Directorate's Australian Cyber Security Centre (ACSC), the Communications Security Establishment Canada (CSE), the U.S. Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the National Security Agency (NSA). Another notable tactic out...
