A critical infrastructure entity within Ukraine was targeted by a previously unseen data wiper malware named PathWiper, according to new findings from Cisco Talos. "The attack was instrumented via a legitimate endpoint administration framework, indicating that the attackers likely had access to the administrative console, that was then used to issue malicious commands and deploy PathWiper across connected endpoints," researchers Jacob Finn, Dmytro Korzhevin, and Asheer Malhotra said in an analysis published Thursday. The attack is assessed to be the work of a Russia-nexus advanced persistent threat (APT) actor based on the tradecraft observed and the overlapping capabilities with destructive malware used in attacks against Ukraine. Talos said the commands issued by the administrative tool's console were received by its client running on the victim endpoints and then executed as a batch (BAT) file. The BAT file, in turn, consisted of a command to run a malicious Visu...

In the wake of high-profile attacks on UK retailers Marks & Spencer and Co-op, Scattered Spider has been all over the media, with coverage spilling over into the mainstream news due to the severity of the disruption caused — currently looking like hundreds of millions in lost profits for M&S alone.  This coverage is extremely valuable for the cybersecurity community as it raises awareness of the battles that security teams are fighting every day. But it's also created a lot of noise that can make it tricky to understand the big picture.  The headline story from the recent campaign against UK retailers is the use of help desk scams. This typically involves the attacker calling up a company's help desk with some level of information — at minimum, PII that allows them to impersonate their victim, and sometimes a password, leaning heavily on their native English-speaking abilities to trick the help desk operator into giving them access to a user account.  Help Des...

The China-linked threat actor behind the recent in-the-wild exploitation of a critical security flaw in SAP NetWeaver has been attributed to a broader set of attacks targeting organizations in Brazil, India, and Southeast Asia since 2023. "The threat actor mainly targets the SQL injection vulnerabilities discovered on web applications to access the SQL servers of targeted organizations," Trend Micro security researcher Joseph C Chen said in an analysis published this week. "The actor also takes advantage of various known vulnerabilities to exploit public-facing servers." Some of the other prominent targets of the adversarial collective include Indonesia, Malaysia, the Philippines, Thailand, and Vietnam. The cybersecurity company is tracking the activity under the moniker Earth Lamia , stating the activity shares some degree of overlap with threat clusters documented by Elastic Security Labs as REF0657 , Sophos as STAC6451 , and Palo Alto Networks Unit 42 as CL-...

Fake installers for popular artificial intelligence (AI) tools like OpenAI ChatGPT and InVideo AI are being used as lures to propagate various threats, such as the CyberLock and Lucky_Gh0$t ransomware families, and a new malware dubbed Numero. "CyberLock ransomware, developed using PowerShell, primarily focuses on encrypting specific files on the victim's system," Cisco Talos researcher Chetan Raghuprasad said in a report published today. "Lucky_Gh0$t ransomware is yet another variant of the Yashma ransomware, which is the sixth iteration of the Chaos ransomware series, featuring only minor modifications to the ransomware binary." Numero, on the other hand, is a destructive malware that impacts victims by manipulating the graphical user interface (GUI) components of their Windows operating system, thereby rendering the machines unusable. The cybersecurity company said the legitimate versions of the AI tools are popular in the business-to-business (B2B) sal...

The threat actors behind the DragonForce ransomware gained access to an unnamed Managed Service Provider's (MSP) SimpleHelp remote monitoring and management (RMM) tool, and then leveraged it to exfiltrate data and drop the locker on multiple endpoints. It's believed that the attackers exploited a trio of security flaws in SimpleHelp (CVE-2024-57727, CVE-2024-57728, and CVE-2024-57726) that were disclosed in January 2025 to access the MSP's SimpleHelp deployment, according to an analysis from Sophos. The cybersecurity company said it was alerted to the incident following a suspicious installation of a SimpleHelp installer file, pushed via a legitimate SimpleHelp RMM instance that's hosted and operated by the MSP for their customers. The threat actors have also been found to leverage their access through the MSP's RMM instance to collect information from different customer environments about device names and configuration, users, and network connections. Altho...

An Iranian national has pleaded guilty in the U.S. over his involvement in an international ransomware and extortion scheme involving the Robbinhood ransomware. Sina Gholinejad (aka Sina Ghaaf), 37, and his co-conspirators are said to have breached the computer networks of various organizations in the United States and encrypted files with Robbinhood ransomware to demand Bitcoin ransom payments. Gholinejad, who was arrested in North Carolina in early January, pleaded guilty to one count of computer fraud and abuse and one count of conspiracy to commit wire fraud. He faces a maximum penalty of 30 years in prison. He is scheduled for sentencing in August 2025. "These cyber attacks caused significant disruptions and tens of millions in losses, including to the City of Greenville, North Carolina, and the City of Baltimore, Maryland," the U.S. Department of Justice (DoJ) said . "Baltimore lost more than $19 million from the damage caused to their computer networks and t...

Stealer malware no longer just steals passwords. In 2025, it steals live sessions—and attackers are moving faster and more efficiently than ever. While many associate account takeovers with personal services, the real threat is unfolding in the enterprise. Flare's latest research, The Account and Session Takeover Economy , analyzed over 20 million stealer logs and tracked attacker activity across Telegram channels and dark web marketplaces. The findings expose how cybercriminals weaponize infected employee endpoints to hijack enterprise sessions—often in less than 24 hours. Here's the real timeline of a modern session hijacking attack. Infection and Data Theft in Under an Hour Once a victim runs a malicious payload—typically disguised as cracked software, fake updates, or phishing attachments—commodity stealers like Redline (44% of logs), Raccoon (25%), and LummaC2 (18%) take over. These malware kits: Extract browser cookies, saved credentials, session tokens, and crypto walle...

The U.S. Federal Bureau of Investigation (FBI) has warned of social engineering attacks mounted by a criminal extortion actor known as Luna Moth targeting law firms over the past two years. The campaign leverages "information technology (IT) themed social engineering calls, and callback phishing emails, to gain remote access to systems or devices and steal sensitive data to extort the victims," the FBI said in an advisory. Luna Moth, also called Chatty Spider, Silent Ransom Group (SRG), Storm-0252, and UNC3753, is known to be active since at least 2022 , primarily employing a tactic called callback phishing or telephone-oriented attack delivery (TOAD) to trick unsuspecting users into calling phone numbers listed in benign-looking phishing emails related to invoices and subscription payments. It's worth mentioning here that Luna Moth refers to the same hacking crew that previously carried out BazarCall (aka BazaCall) campaigns to deploy ransomware like Conti . The ...

The malware known as Latrodectus has become the latest to embrace the widely-used social engineering technique called ClickFix as a distribution vector. "The ClickFix technique is particularly risky because it allows the malware to execute in memory rather than being written to disk," Expel said in a report shared with The Hacker News. "This removes many opportunities for browsers or security tools to detect or block the malware." Latrodectus, believed to be a successor to IcedID, is the name given to a malware that acts as a downloader for other payloads, such as ransomware. It was first documented by Proofpoint and Team Cymru in April 2024.

As part of the latest "season" of Operation Endgame , a coalition of law enforcement agencies have taken down about 300 servers worldwide, neutralized 650 domains, and issued arrest warrants against 20 targets. Operation Endgame, first launched in May 2024, is an ongoing law enforcement operation targeting services and infrastructures assisting in or directly providing initial or consolidating access for ransomware. The previous edition focused on dismantling the initial access malware families that have been used to deliver ransomware. The latest iteration, per Europol, targeted new malware variants and successor groups that re-emerged after last year's takedowns such as Bumblebee, Lactrodectus, QakBot, HijackLoader, DanaBot, TrickBot, and WARMCOOKIE . The interaction action was carried out between May 19 and 22, 2025. "In addition, €3.5 million in cryptocurrency was seized during the action week, bringing the total amount seized during the Operation Endgame to...

The U.S. Department of Justice (DoJ) on Thursday announced the disruption of the online infrastructure associated with DanaBot (aka DanaTools) and unsealed charges against 16 individuals for their alleged involvement in the development and deployment of the malware, which it said was controlled by a Russia-based cybercrime organization. The malware, the DoJ said, infected more than 300,000 victim computers around the world, facilitated fraud and ransomware, and caused at least $50 million in damages. Two of the defendants, Aleksandr Stepanov (aka JimmBee), 39, and Artem Aleksandrovich Kalinkin (aka Onix), 34, both from Novosibirsk, Russia, are currently at large. Stepanov has been charged with conspiracy, conspiracy to commit wire fraud and bank fraud, aggravated identity theft, unauthorized access to a protected computer to obtain information, unauthorized impairment of a protected computer, wiretapping, and use of an intercepted communication. Kalinkin has been charged with cons...

A sprawling operation undertaken by global law enforcement agencies and a consortium of private sector firms has disrupted the online infrastructure associated with a commodity information stealer known as Lumma (aka LummaC or LummaC2), seizing 2,300 domains that acted as the command-and-control (C2) backbone to commandeer infected Windows systems. "Malware like LummaC2 is deployed to steal sensitive information such as user login credentials from millions of victims in order to facilitate a host of crimes, including fraudulent bank transfers and cryptocurrency theft," the U.S. Department of Justice (DoJ) said in a statement. The confiscated infrastructure has been used to target millions across the world through affiliates and other cyber criminals. Lumma Stealer, active since late 2022, is estimated to have been used in at least 1.7 million instances to steal information, such as browser data, autofill information, login credentials, and cryptocurrency seed phrases.
