New research from Broadcom's Symantec and Carbon Black Threat Hunter Team has discovered evidence of an Iranian hacking group embedding itself in several U.S. companies' networks, including banks, airports, non-profit, and the Israeli arm of a software company. The activity has been attributed to a state-sponsored hacking group called MuddyWater (aka Seedworm). It's affiliated with the Iranian Ministry of Intelligence and Security (MOIS). The campaign is assessed to have begun in early February, with recent activity detected following U.S. and Israeli military strikes on Iran . "The software company is a supplier to the defense and aerospace industries, among others, and has a presence in Israel, with the company's Israel operation seeming to be the target in this activity," the security vendor said in a report shared with The Hacker News. The attacks targeting the software company, as well as a U.S. bank and a Canadian non-profit, have been found to p...

A China-linked advanced persistent threat (APT) actor has been targeting critical telecommunications infrastructure in South America since 2024, targeting Windows and Linux systems and edge devices with three different implants. The activity is being tracked by Cisco Talos under the moniker UAT-9244 , describing it as closely associated with another cluster known as FamousSparrow . It's worth noting that FamousSparrow is assessed to share tactical overlaps with Salt Typhoon , a China-nexus espionage group known for its targeting of telecommunication service providers. Despite the similar targeting footprint between UAT-9244 and Salt Typhoon, there is no conclusive evidence that ties the two clusters together. In the campaign analyzed by the cybersecurity company, the attack chains have been found to distribute three previously undocumented implants: TernDoor targeting Windows, PeerTime (aka angrypeer) targeting Linux, and BruteEntry, which is installed on network edge device...

Microsoft on Thursday disclosed details of a new widespread ClickFix social engineering campaign that has leveraged the Windows Terminal app as a way to activate a sophisticated attack chain and deploy the Lumma Stealer malware. The activity, observed in February 2026, makes use of the terminal emulator program instead of instructing users to launch the Windows Run dialog and paste a command into it. "This campaign instructs targets to use the Windows + X → I shortcut to launch Windows Terminal (wt.exe) directly, guiding users into a privileged command execution environment that blends into legitimate administrative workflows and appears more trustworthy to users," the Microsoft Threat Intelligence team said in a series of posts on X. What makes the latest variant notable is that it bypasses detections specifically designed to flag Run dialog abuse, not to mention take advantage of the legitimacy of Windows Terminal to trick unsuspecting users into running malicious ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added two security flaws impacting Hikvision and Rockwell Automation products to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The critical-severity vulnerabilities are listed below - CVE-2017-7921 (CVSS score: 9.8) - An improper authentication vulnerability affecting multiple Hikvision products that could allow a malicious user to escalate privileges on the system and gain access to sensitive information.  CVE-2021-22681 (CVSS score: 9.8) - An insufficiently protected credentials vulnerability affecting multiple Rockwell Automation Studio 5000 Logix Designer, RSLogix 5000, and Logix Controllers that could allow an unauthorized user with network access to the controller to bypass the verification mechanism and authenticate with it, as well as alter its configuration and/or application code. The addition of CVE-2017-7921 to the KEV catalog comes more...

Cisco has disclosed that two more vulnerabilities affecting Catalyst SD-WAN Manager (formerly SD-WAN vManage) have come under active exploitation in the wild. The vulnerabilities in question are listed below - CVE-2026-20122 (CVSS score: 7.1) - An arbitrary file overwrite vulnerability that could allow an authenticated, remote attacker to overwrite arbitrary files on the local file system. Successful exploitation requires the attacker to have valid read-only credentials with API access on the affected system. CVE-2026-20128 (CVSS score: 5.5) - An information disclosure vulnerability that could allow an authenticated, local attacker to gain Data Collection Agent (DCA) user privileges on an affected system. Successful exploitation requires the attacker to have valid vManage credentials on the affected system. Patches for the security defects, along with CVE-2026-20126, CVE-2026-20129, and CVE-2026-20133, were released by Cisco late last month in the following versions - Earli...

Most organizations assume encrypted data is safe. But many attackers are already preparing for a future where today’s encryption can be broken. Instead of trying to decrypt information now, they are collecting encrypted data and storing it so it can be decrypted later using quantum computers. This tactic—known as “harvest now, decrypt later” —means sensitive data transmitted today could become readable years from now once quantum capabilities mature. Security leaders who want to understand this risk and how to prepare can explore it in detail in the upcoming webinar on Post-Quantum Cryptography best practices , where experts will explain practical ways organizations can begin protecting data before quantum decryption becomes possible. Why Post-Quantum Cryptography Matters Quantum computing is advancing quickly, and most modern encryption algorithms, such as RSA and ECC, will not remain secure forever. For organizations that must keep data confidential for many years—financial r...

Some weeks in cybersecurity feel routine. This one doesn’t. Several new developments surfaced over the past few days, showing how quickly the threat landscape keeps shifting. Researchers uncovered fresh activity, security teams shared new findings, and a few unexpected moves from major tech companies also drew attention. Together, these updates offer a useful snapshot of what is happening behind the scenes in the cyber world right now. From new tactics and campaigns to security and policy changes that could affect millions of users, there is a lot unfolding at once. Below is a quick roundup of the most notable stories making headlines this week. Phishing Campaign Deploys Multiple Malware Strains Ukraine Targeted by SHADOWSNIFF, SALATSTEALER, DEAFTICKK Malware The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a hacking campaign targeting Ukrainian government institutions using phishing emails containing a...

A suspected Iran-nexus threat actor has been attributed to a campaign targeting government officials in Iraq by impersonating the country's Ministry of Foreign Affairs to deliver a set of never-before-seen malware. Zscaler ThreatLabz, which observed the activity in January 2026, is tracking the cluster under the name Dust Specter . The attacks, which manifest in the form of two different infection chains, culminate in the deployment of malware dubbed SPLITDROP, TWINTASK, TWINTALK, and GHOSTFORM. "Dust Specter used randomly generated URI paths for command-and-control (C2) communication with checksum values appended to the URI paths to ensure that these requests originated from an actual infected system," security researcher Sudeep Singh said . "The C2 server also utilized geofencing techniques and User-Agent verification." A notable aspect of the campaign is the compromise of the Iraqi government-related infrastructure to stage malicious payloads, not to me...

Organizations typically roll out multi-factor authentication (MFA) and assume stolen passwords are no longer enough to access systems. In Windows environments, that assumption is often wrong. Attackers still compromise networks every day using valid credentials. The issue is not MFA itself, but coverage.  Enforced through an identity provider (IdP) such as Microsoft Entra ID, Okta, or Google Workspace, MFA works well for cloud apps and federated sign-ins. But many Windows logons rely solely on Active Directory (AD) authentication paths that never trigger MFA prompts. To reduce credential-based compromise, security teams need to understand where Windows authentication happens outside their identity stack. Seven Windows authentication paths that attackers rely on 1. Interactive Windows logon (local or domain joined) When a user signs in directly to a Windows workstation or server, authentication is typically handled by AD (via Kerberos or NTLM), not by a cloud IdP.  In h...

Cybersecurity researchers have disclosed details of a new Russian cyber campaign that has targeted Ukrainian entities with two previously undocumented malware families named BadPaw and MeowMeow . "The attack chain initiates with a phishing email containing a link to a ZIP archive. Once extracted, an initial HTA file displays a lure document written in Ukrainian concerning border crossing appeals to deceive the victim," ClearSky said in a report published this week. In parallel, the attack chain leads to the deployment of a .NET-based loader called BadPaw, which then establishes communication with a remote server to fetch and deploy a sophisticated backdoor called MeowMeow. The campaign has been attributed with moderate confidence to the Russian state-sponsored threat actor known as APT28 , based on the targeting footprint, the geopolitical nature of the lures used, and overlaps with techniques observed in previous Russian cyber operations. 

Tycoon 2FA , one of the prominent phishing-as-a-service (PhaaS) toolkits that allowed cybercriminals to stage adversary-in-the-middle (AitM) credential harvesting attacks at scale, was dismantled by a coalition of law enforcement agencies and security companies. The subscription-based phishing kit , which first emerged in August 2023 , was described by Europol as one of the largest phishing operations worldwide. The kit was sold via Telegram and Signal for a starting price of $120 for 10 days or $350 for access to a web-based administration panel for a month. Tycoon 2FA's primary developer is alleged to be Saad Fridi , who is said to be based in Pakistan. The panel serves as a hub for configuring, tracking, and refining campaigns. It features pre‑built templates, attachment files for common lure formats, domain and hosting configuration, redirect logic, and victim tracking. Operators can also configure how the malicious content is delivered through attachments, as well as kee...

A joint law enforcement operation has dismantled LeakBase , one of the world's largest online forums for cybercriminals to buy and sell stolen data and cybercrime tools. The LeakBase forum, per the U.S. Department of Justice (DoJ), had over 142,000 members and more than 215,000 messages between members as of December 2025. Those attempting to access the forum's website (" leakbase[.]la ") are now greeted with a seizure banner that says it was confiscated by the U.S. Federal Bureau of Investigation (FBI) as part of an international law enforcement effort. "All forum content, including users' accounts, posts, credit details, private messages, and IP logs, has been secured and preserved for evidentiary purposes," the banner reads. Available in English and accessible over the clearnet, LeakBase offered hacked databases , including hundreds of millions of account credentials and financial information such as credit and debit card numbers, banking account ...
