An active phishing campaign has been observed targeting multiple vectors since at least April 2025, with legitimate Remote Monitoring and Management (RMM) software as a way to establish persistent remote access to compromised hosts. The activity, codenamed VENOMOUS#HELPER , has impacted over 80 organizations, most of which are in the U.S., according to Securonix. It shares overlaps with clusters previously tracked by Red Canary and Sophos, the latter of which has given it the moniker STAC6405 . While it's not clear who is behind the campaign, the cybersecurity company said it aligns with a financially motivated Initial Access Broker (IAB) or a ransomware precursor operation. "In this case, a customized SimpleHelp and ScreenConnect RMMs are used to bypass defenses as they are legitimately installed by the unsuspecting victim," researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a report shared with The Hacker News. Setting aside the fact that the...

Progress Software has released updates to address two security flaws in MOVEit Automation, including a critical bug that could result in an authentication bypass. MOVEit Automation (formerly Central) is a secure, server-based managed file transfer (MFT) solution used to schedule and automate file movement workflows in enterprise environments without requiring any custom scripts.  The vulnerabilities in question are CVE-2026-4670 (CVSS score: 9.8), an authentication bypass vulnerability, and CVE-2026-5174 (CVSS score: 7.7), an improper input validation vulnerability that could allow privilege escalation. "Critical and high vulnerabilities in MOVEit Automation may allow authentication bypass and privilege escalation through the service backend command port interfaces," Progress Software said in an advisory. "Exploitation may lead to unauthorized access, administrative control, and data exposure." The shortcomings affect the following versions - MOVEit Autom...

On December 4, 2025, a 17-year-old was arrested in Osaka under Japan’s Unauthorized Access Prohibition Act. The young man had run malicious code to extract the personal data of over 7 million users of Kaikatsu Club , Japan's largest internet cafe chain. When asked, the young man shared his motivation for the hack: he wanted to buy Pokémon cards. In a sense, this is a fairly conventional story. Since the 1990s, we’ve read about computing wunderkinds such as Kevin Mitnick, whose technical ability exceeded their judgment and who were drawn into high-profile cybercrimes in pursuit of status, profit, or excitement. But something is different in this story: the young man in question wasn’t technical. The rise of AI-assisted attacks In 2025, LLM-backed chat and agent systems crossed a threshold, going from useful but error-prone coding assistants to end-to-end coding powerhouses. Throughout the year, several measures of cybercrime frequency and severity approximately doubled. Instanc...

The China-based cybercrime group known as Silver Fox has been linked to a new campaign targeting organizations in Russia and India with a new malware called ABCDoor . The activity involved using phishing emails that mimic correspondence from the Income Tax Department of India in December 2025, followed by a similar campaign aimed at Russian entities. "Both waves followed a nearly identical structure: phishing emails were styled as official notices regarding tax audits or prompted users to download an archive containing a 'list of tax violations,'" Kaspersky said . "Inside the archive was a modified Rust-based loader pulled from a public repository. This loader would download and execute the well-known ValleyRAT backdoor." The campaign is estimated to have impacted organizations across the industrial, consulting, retail, and transportation sectors. More than 1,600 phishing emails were flagged between early January and early February. What's notab...

A coordinated international operation involving U.S. and Chinese authorities has arrested at least 276 suspects and shut down nine scam centers used for cryptocurrency investment fraud schemes targeting Americans, resulting in millions of dollars in losses. The crackdown was led by the Dubai Police, under the United Arab Emirates (UAE) Ministry of Interior, in partnership with the U.S. Federal Bureau of Investigation (FBI) and the Chinese Ministry of Public Security. Among those arrested are individuals from Burma and Indonesia, who were apprehended by authorities from Dubai and Thailand. Thet Min Nyi, 27, Wiliang Awang, 23, Andreas Chandra, 29, Lisa Mariam, 29, and two fugitive co-conspirators have been charged with federal fraud and money laundering charges in the U.S. "Fraudsters who target Americans from overseas cannot operate with impunity, no matter where in the world they reside," Assistant Attorney General A. Tysen Duva of the Justice Department's (DoJ) Crimi...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added a recently disclosed security flaw impacting various Linux distributions to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerability, tracked as CVE-2026-31431 (CVSS score: 7.8), is a case of local privilege escalation (LPE) flaw that could allow an unprivileged local user to obtain root. The nine-year-old flaw is also tracked as Copy Fail by Theori and Xint. Fixes have been made available in Linux kernel versions 6.18.22, 6.19.12, and 7.0. "Linux Kernel contains an incorrect resource transfer between spheres vulnerability that could allow for privilege escalation," CISA said in an advisory. In a write-up published earlier this week, the researchers said Copy Fail is the result of a logic bug in the Linux kernel's authentication cryptographic template that allows an attacker to reliably trigger privilege escalation tri...

A newly discovered Vietnamese-linked operation has been observed using a Google AppSheet as a "phishing relay" to distribute phishing emails with an aim to compromise Facebook accounts. The activity has been codenamed AccountDumpling by Guardio, with the scheme selling the stolen accounts back through an illicit storefront run by the threat actors. In all, roughly 30,000 Facebook accounts are estimated to have been hacked as part of the campaign. "What we found wasn't a single phishing kit," security researcher Shaked Chen wrote in a report shared with The Hacker News. "It was a living operation with real-time operator panels, advanced evasion, continuous evolution and a criminal-commercial loop that quietly feeds on the same accounts it helps steal back." The findings are just the latest example of how Vietnamese threat actors continue to embrace various tactics to gain unauthorized access to victims' Facebook accounts, which are then sold...

Cybersecurity researchers are warning of two cybercrime groups that are carrying out "rapid, high-impact attacks" operating almost within the confines of SaaS environments, while leaving minimal traces of their actions. The clusters, Cordial Spider (aka BlackFile, CL-CRI-1116, O-UNC-045, and UNC6671) and Snarky Spider (aka O-UNC-025 and UNC6661), have been attributed to high-speed data theft and extortion campaigns that share a remarkable degree of operational similarities. Both hacking groups are assessed to be active since at least October 2025, with the latter a native English-speaking crew sharing ties to the e-crime ecosystem known as The Com . "In most cases, these adversaries use voice phishing (vishing) to direct targeted users to malicious, SSO-themed adversary-in-the-middle (AiTM) pages, where they capture authentication data and pivot directly into SSO-integrated SaaS applications," CrowdStrike's Counter Adversary Operations said in a report. ...

Cybersecurity researchers have disclosed details of a new China-aligned espionage campaign targeting government and defense sectors across South, East, and Southeast Asia, along with one European government belonging to NATO. Trend Micro has attributed the activity to a threat activity cluster it tracks under the temporary designation SHADOW-EARTH-053 . The adversarial collective is assessed to be active since at least December 2024, while sharing some level of network overlap with CL-STA-0049, Earth Alux, and REF7707 . "The group exploits N-day vulnerabilities in internet-facing Microsoft Exchange and Internet Information Services (IIS) servers (e.g., ProxyLogon chain), then deploys web shells ( Godzilla ) for persistent access and stages ShadowPad implants via DLL sideloading of legitimate signed executables," security researchers Daniel Lunghi and Lucas Silva said in an analysis. Targets of the campaigns include Pakistan, Thailand, Malaysia, India, Myanmar, Sri Lank...

Cybersecurity researchers have disclosed details of a stealthy Python-based backdoor framework called DEEP#DOOR that comes with capabilities to establish persistent access and harvest a wide range of sensitive information from compromised hosts. "The intrusion chain begins with execution of a batch script ('install_obf.bat') that disables Windows security controls, dynamically extracts an embedded Python payload ('svc.py'), and establishes persistence through multiple mechanisms including Startup folder scripts, registry Run keys, scheduled tasks, and optional WMI subscriptions," Securonix researchers Akshay Gaikwad, Shikha Sangwan, and Aaron Beardslee said in a report shared with The Hacker News. It's assessed that the batch script is distributed via traditional approaches like phishing. It's currently not known how widespread attacks distributing the malware are, and if any of those infections have been successful. "Based on our current a...

Intro A sophisticated, high-resilience malicious campaign was identified by Atos Threat Research Center (TRC) in March 2026. This operation specifically targets the high-privilege professional accounts of enterprise administrators, DevOps engineers, and security analysts by impersonating administrative utilities they rely on for daily operations. By integrating  Search Engine Order (SEO) poisoning , a  dual-stage GitHub distribution architecture , and  decentralized blockchain-based command-and-control (C2) resolving, Threat Actors have established a highly resilient delivery and persistence mechanism. Creative Distribution via GitHub Facades The campaign utilizes a multi-layered delivery chain designed to evade platform-level takedowns and maintain a high search engine ranking. The attack begins with  SEO poisoning on various search engines, including Bing, Yahoo, DuckDuckGo, and Yandex. That ensures that malicious results for niche IT terms rank at the top of...

In February 2026, researchers uncovered a shift that completely changed the game: threat actors are now using custom AI setups to automate attacks directly into the kill chain. We aren't just talking about AI writing better phishing emails anymore. We’re talking about autonomous agents mapping Active Directory and seizing Domain Admin credentials in minutes. The problem? Most defensive workflows still look like this: your CTI team finds a threat, they pass it to the Red Team to test, and eventually, the results reach the Blue Team for patching. This process is full of friction, silos, and delays. The reality is simple: You cannot fight an AI adversary moving at machine speed when your defense moves at the speed of a calendar invite. To bridge this gap, we’re hosting a technical deep dive with the team at Picus Security to unveil a new defensive paradigm: Autonomous Exposure Validation .

Threat hunters are warning that the cybercriminal operation known as VECT 2.0 acts more like a wiper than a ransomware due to a critical flaw in its encryption implementation across Windows, Linux, and ESXi variants that renders recovery impossible even for the threat actors. The fact that VECT's locker permanently destroys large files rather than encrypting them means even victims who opt to pay the ransom cannot get their data back, as the decryption keys are discarded by the malware during the time encryption occurs. "VECT is being marketed as ransomware, but for any file over 131KB – which is most of what enterprises actually care about – it functions as a data destruction tool," Eli Smadja, group manager at Check Point Research, said in a statement shared with The Hacker News. "CISOs need to understand that in a VECT incident, paying is not a recovery strategy. There is no decrypter that can be handed over, not because the attackers are unwilling, but beca...

Microsoft on Monday revised its advisory for a now-patched, high-severity security flaw impacting Windows Shell to acknowledge that it has been actively exploited in the wild. The vulnerability in question is CVE-2026-32202 (CVSS score: 4.3), a spoofing vulnerability that could allow an attacker to access sensitive information. It was addressed as part of its Patch Tuesday update for this month. "Protection mechanism failure in Windows Shell allows an unauthorized attacker to perform spoofing over a network," Microsoft noted in an alert. "An attacker would have to send the victim a malicious file that the victim would have to execute." "An attacker who successfully exploited the vulnerability could view some sensitive information (Confidentiality) but not all resources within the impacted component may be divulged to the attacker. The attacker cannot make changes to disclosed information (Integrity) or limit access to the resource (Availability)."...

A pro-Ukrainian hacktivist group called PhantomCore has been attributed to attacks actively targeting servers running TrueConf video conferencing software in Russia since September 2025. That's according to a report published by Positive Technologies, which found the threat actors to be leveraging an exploit chain comprising three vulnerabilities to execute commands remotely on susceptible servers.     "Despite the fact that there are no exploits for this chain of vulnerability in public access, attackers from PhantomCore managed to conduct their research and reproduce vulnerabilities, which led to a large number of cases of its operation in Russian organizations," researchers Daniil Grigoryan and Georgy Khandozhko said . PhantomCore , also called Fairy Trickster, Head Mare, Rainbow Hyena, and UNG0901, is the name assigned to a politically- and financially-motivated hacking crew that has been active since 2022 following the Russo-Ukrainian war. Attacks   mo...

Cybersecurity researchers have flagged dozens of Microsoft Visual Studio Code (VS Code) extensions on the Open VSX repository that are linked to a persistent information-stealing campaign dubbed GlassWorm . The cluster of 73 extensions has been identified as cloned versions of their legitimate counterparts. Of these, six have been confirmed to be malicious, with the remaining acting as seemingly harmless sleeper packages to get users to download them and build trust, before their true intent is manifested through a subsequent update. All the extensions were published at the start of the month, per application security company Socket, which is tracking the latest iteration under the moniker GlassWorm v2 . In total, more than 320 artifacts have been identified since December 21, 2025. The list of extensions identified as malicious is below - outsidestormcommand.monochromator-theme keyacrosslaud.auto-loop-for-antigravity krundoven.ironplc-fast-hub boulderzitunnel.vscode-buddies ...

Cybersecurity researchers have disclosed details of a telecommunications fraud campaign that uses fake CAPTCHA verification tricks to dupe unsuspecting users into sending international text messages that incur charges on their mobile bills, generating illicit revenue for the threat actors who lease the phone numbers. According to a new report published by Infoblox, the operation is believed to have been active since at least June 2020, using methods like social engineering and back button hijacking in web browsers. As many as 35 phone numbers spanning 17 countries have been observed as part of the international revenue share fraud ( IRSF ) campaign. "The fake CAPTCHA has multiple steps, and each message crafted by the site is preconfigured with over a dozen phone numbers, meaning the victim isn't charged for just a single message – they're charged for sending SMSs to over 50 international destinations," researchers David Brunsdon and Darby Wise said in an analysi...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added four vulnerabilities impacting SimpleHelp, Samsung MagicINFO 9 Server, and D-Link DIR-823X series routers to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The list of vulnerabilities is below - CVE-2024-57726 (CVSS score: 9.9) - A missing authorization vulnerability in SimpleHelp that could allow low-privileged technicians to create API keys with excessive permissions, which can then be used to escalate privileges to the server admin role. CVE-2024-57728 (CVSS score: 7.2) - A path traversal vulnerability in SimpleHelp that allows admin users to upload arbitrary files anywhere on the file system by uploading a crafted zip file (i.e., zip slip), which can be exploited to execute arbitrary code on the host in the context of the SimpleHelp server user. CVE-2024-7399 (CVSS score: 8.8) - A path traversal vulnerability in Samsung MagicINFO 9 Server that cou...

Chinese-speaking individuals are the target of a new campaign that uses a trojanized version of SumatraPDF reader to deploy the AdaptixC2 Beacon post-exploitation agent and ultimately facilitate the abuse of Microsoft Visual Studio Code (VS Code) tunnels for remote access. Zscaler ThreatLabz, which discovered the campaign last month, has attributed it with high confidence to Tropic Trooper (aka APT23, Earth Centaur, KeyBoy, and Pirate Panda), a hacking group known for its targeting of various entities in Taiwan, Hong Kong, and the Philippines. It's assessed to be active since at least 2011. "The threat actors created a custom AdaptixC2 Beacon listener, leveraging GitHub as their command-and-control (C2) platform," security researcher Yin Hong Chang said in an analysis. It's believed that Chinese-speaking individuals in Taiwan, and individuals in South Korea and Japan, are the targets of the campaign. The starting point of the attack is a ZIP archive containing...

A previously undocumented threat activity cluster known as UNC6692 has been observed leveraging social engineering tactics via Microsoft Teams to deploy a custom malware suite on compromised hosts. "As with many other intrusions in recent years, UNC6692 relied heavily on impersonating IT help desk employees, convincing their victim to accept a Microsoft Teams chat invitation from an account outside their organization," Google-owned Mandiant said in a report published today. UNC6692 has been attributed to a large email campaign that's designed to overwhelm a target's inbox with a flood of spam emails, creating a false sense of urgency. The threat actor then approaches the target over Microsoft Teams by sending a message claiming to be from the IT support team to offer assistance with the email bombing problem. It's worth noting that this combination of bombarding a victim's email inbox followed by Microsoft Teams-based help desk impersonation has been a ...
