Threat actors are leveraging public GitHub repositories to host malicious payloads and distribute them via Amadey as part of a campaign observed in April 2025. "The MaaS [malware-as-a-service] operators used fake GitHub accounts to host payloads, tools, and Amadey plug-ins, likely as an attempt to bypass web filtering and for ease of use," Cisco Talos researchers Chris Neal and Craig Jackson said in a report published today. The cybersecurity company said the attack chains leverage a malware loader called Emmenhtal (aka PEAKLIGHT) to deliver Amadey, which, for its part, downloads various custom payloads from public GitHub repositories operated by the threat actors. The activity shares tactical similarities with an email phishing campaign that used invoice payment and billing-related lures to distribute SmokeLoader via Emmenhtal in February 2025 in attacks targeting Ukrainian entities. Both Emmenhtal and Amadey function as a downloader for secondary payloads like info...

Cybersecurity researchers have flagged a new variant of a known malware loader called Matanbuchus that packs in significant features to enhance its stealth and evade detection. Matanbuchus is the name given to a malware-as-a-service (MaaS) offering that can act as a conduit for next-stage payloads , including Cobalt Strike beacons and ransomware. First advertised in February 2021 on Russian-speaking cybercrime forums for a rental price of $2,500, the malware has been put to use as part of ClickFix-like lures to trick users visiting legitimate-but-compromised sites not running it. Matanbuchus's delivery methods have evolved over time, leveraging phishing emails pointing to booby-trapped Google Drive links, drive-by downloads from compromised sites, malicious MSI installers , and malvertising . It has been used to deploy a variety of secondary payloads including DanaBot, QakBot, and Cobalt Strike, all known precursors to ransomware deployment. The latest version of the loade...

Social engineering attacks have entered a new era—and they're coming fast, smart, and deeply personalized. It's no longer just suspicious emails in your spam folder. Today's attackers use generative AI, stolen branding assets, and deepfake tools to mimic your executives, hijack your social channels, and create convincing fakes of your website, emails, and even voice. They don't just spoof— they impersonate. Modern attackers aren't relying on chance. They're running long-term, multi-channel campaigns across email, LinkedIn, SMS, and even support portals—targeting your employees, customers, and partners. Whether it's a fake recruiter reaching out on LinkedIn, a lookalike login page sent via text, or a cloned CFO demanding a wire transfer, the tactics are faster, more adaptive, and increasingly automated using AI. The result? Even trained users are falling for sophisticated fakes—because they're not just phishing links anymore. They're operations. This Webinar Shows You How to Fight...

Cryptocurrency users are the target of an ongoing social engineering campaign that employs fake startup companies to trick users into downloading malware that can drain digital assets from both Windows and macOS systems. "These malicious operations impersonate AI, gaming, and Web3 firms using spoofed social media accounts and project documentation hosted on legitimate platforms like Notion and GitHub," Darktrace researcher Tara Gould said in a report shared with The Hacker News. The elaborate social media scam has been for sometime now, with a previous iteration in December 2024 leveraging bogus videoconferencing platforms to dupe victims into joining a meeting under the pretext of discussing an investment opportunity after approaching them on messaging apps like Telegram. Users who ended up downloading the purported meeting software were stealthily infected by stealer malware such as Realst. The campaign was codenamed Meeten by Cado Security (which was acquired by Dark...

The U.K. National Crime Agency (NCA) on Thursday announced that four people have been arrested in connection with cyber attacks targeting major retailers Marks & Spencer, Co-op, and Harrods. The arrested individuals include two men aged 19, a third aged 17, and a 20-year-old woman. They were apprehended in the West Midlands and London on suspicion of Computer Misuse Act offenses, blackmail, money laundering, and participating in the activities of an organized crime group. All four suspects were arrested from their homes and their electronic devices have been seized for further forensic analysis. Their names were not disclosed. "Since these attacks took place, specialist NCA cybercrime investigators have been working at pace and the investigation remains one of the Agency's highest priorities," Deputy Director Paul Foster, head of the NCA's National Cyber Crime Unit, said in a statement. "Today's arrests are a significant step in that investigation ...

From overprivileged admin roles to long-forgotten vendor tokens, these attackers are slipping through the cracks of trust and access. Here's how five retail breaches unfolded, and what they reveal about... In recent months, major retailers like Adidas, The North Face, Dior, Victoria's Secret, Cartier, Marks & Spencer, and Co‑op have all been breached. These attacks weren't sophisticated malware or zero-day exploits. They were identity-driven, exploiting overprivileged access and unmonitored service accounts, and used the human layer through tactics like social engineering. Attackers didn't need to break in. They logged in. They moved through SaaS apps unnoticed, often using real credentials and legitimate sessions. And while most retailers didn't share all the technical details, the patterns are clear and recurring.  Here's a breakdown of the five recent high-profile breaches in retail: 1. Adidas: Exploiting third-party trust Adidas confirmed a data breach caused by an ...

Cybersecurity researchers have disclosed a malicious campaign that leverages search engine optimization ( SEO ) poisoning techniques to deliver a known malware loader called Oyster (aka Broomstick or CleanUpLoader). The malvertising activity, per Arctic Wolf, promotes fake websites hosting trojanized versions of legitimate tools like PuTTY and WinSCP, aiming to trick software professionals searching for these programs into installing them instead. "Upon execution, a backdoor known as Oyster/Broomstick is installed," the company said in a brief published last week. "Persistence is established by creating a scheduled task that runs every three minutes, executing a malicious DLL (twain_96.dll) via rundll32.exe using the DllRegisterServer export, indicating the use of DLL registration as part of the persistence mechanism." The names of some of the bogus websites are listed below - updaterputty[.]com zephyrhype[.]com putty[.]run putty[.]bet, and puttyy[.]org...

Everything feels secure—until one small thing slips through. Even strong systems can break if a simple check is missed or a trusted tool is misused. Most threats don't start with alarms—they sneak in through the little things we overlook. A tiny bug, a reused password, a quiet connection—that's all it takes. Staying safe isn't just about reacting fast. It's about catching these early signs before they blow up into real problems. That's why this week's updates matter. From stealthy tactics to unexpected entry points, the stories ahead reveal how quickly risk can spread—and what smart teams are doing to stay ahead. Dive in. ⚡ Threat of the Week U.S. Disrupts N. Korea IT Worker Scheme — Prosecutors said they uncovered the North Korean IT staff working at over 100 U.S. companies using fictitious or stolen identities and not only drawing salaries, but also stealing secret data and plundering virtual currency more than $900,000 in one incident targeting an unnamed blockchain company in ...

Cybersecurity researchers have uncovered over 40 malicious browser extensions for Mozilla Firefox that are designed to steal cryptocurrency wallet secrets, putting users' digital assets at risk. "These extensions impersonate legitimate wallet tools from widely-used platforms such as Coinbase, MetaMask, Trust Wallet, Phantom, Exodus, OKX, Keplr, MyMonero, Bitget, Leap, Ethereum Wallet, and Filfox," Koi Security researcher Yuval Ronen said . The large-scale campaign is said to have been ongoing since at least April 2025, with new extensions uploaded to the Firefox Add-ons store as recently as last week. The identified extensions have been found to artificially inflate their popularity, adding hundreds of 5-star reviews that go far beyond the total number of active installations. This strategy is employed to give them an illusion of authenticity, making it seem like they are widely adopted and tricking unsuspecting users into installing them. Another tactic adopted by ...

Threat actors with ties to North Korea have been observed targeting Web3 and cryptocurrency-related businesses with malware written in the Nim programming language, underscoring a constant evolution of their tactics. "Unusually for macOS malware, the threat actors employ a process injection technique and remote communications via wss, the TLS-encrypted version of the WebSocket protocol," SentinelOne researchers Phil Stokes and Raffaele Sabato said in a report shared with The Hacker News. "A novel persistence mechanism takes advantage of SIGINT/SIGTERM signal handlers to install persistence when the malware is terminated or the system rebooted." The cybersecurity company is tracking the malware components collectively under the name NimDoor. It's worth noting that some aspects of the campaign were previously documented by Huntabil.IT and later by Huntress and Validin , but with differences in the payloads deployed. The attack chains involve social enginee...

Cybersecurity researchers are calling attention to phishing campaigns that impersonate popular brands and trick targets into calling phone numbers operated by threat actors. "A significant portion of email threats with PDF payloads persuade victims to call adversary-controlled phone numbers, displaying another popular social engineering technique known as Telephone-Oriented Attack Delivery (TOAD), also known as callback phishing," Cisco Talos researcher Omid Mirzaei said in a report shared with The Hacker News. An analysis of phishing emails with PDF attachments between May 5 and June 5, 2025, has revealed Microsoft and Docusign to be the most impersonated brands. NortonLifeLock, PayPal, and Geek Squad are among the most impersonated brands in TOAD emails with PDF attachments. The activity is part of wider phishing attacks that attempt to leverage the trust people have with popular brands to initiate malicious actions. These messages typically incorporate PDF attachments...

Ever wonder what happens when attackers don't break the rules—they just follow them better than we do? When systems work exactly as they're built to, but that "by design" behavior quietly opens the door to risk? This week brings stories that make you stop and rethink what's truly under control. It's not always about a broken firewall or missed patch—it's about the small choices, default settings, and shortcuts that feel harmless until they're not. The real surprise? Sometimes the threat doesn't come from outside—it's baked right into how things are set up. Dive in to see what's quietly shaping today's security challenges. ⚡ Threat of the Week FBI Warns of Scattered Spider's on Airlines — The U.S. Federal Bureau of Investigation (FBI) has warned of a new set of attacks mounted by the notorious cybercrime group Scattered Spider targeting the airline sector using sophisticated social engineering techniques to obtain initial access. Cybersecurity vendors Palo Alto Networks Unit 4...

The U.S. Federal Bureau of Investigation (FBI) has revealed that it has observed the notorious cybercrime group Scattered Spider broadening its targeting footprint to strike the airline sector. To that end, the agency said it's actively working with aviation and industry partners to combat the activity and help victims. "These actors rely on social engineering techniques, often impersonating employees or contractors to deceive IT help desks into granting access," the FBI said in a post on X. "These techniques frequently involve methods to bypass multi-factor authentication (MFA), such as convincing help desk services to add unauthorized MFA devices to compromised accounts." Scattered Spider attacks are also known to target third-party IT providers to obtain access to large organizations, putting trusted vendors and contractors at risk of potential attacks. The attacks typically pave the way for data theft, extortion, and ransomware. In a statement shared ...

The ClickFix social engineering tactic as an initial access vector using fake CAPTCHA verifications increased by 517% between the second half of 2024 and the first half of this year, according to data from ESET. "The list of threats that ClickFix attacks lead to is growing by the day, including infostealers, ransomware, remote access trojans, cryptominers, post-exploitation tools, and even custom malware from nation-state-aligned threat actors," Jiří Kropáč, Director of Threat Prevention Labs at ESET, said . ClickFix has become a widely popular and deceptive method that employs bogus error messages or CAPTCHA verification checks to entice victims into copying and pasting a malicious script into either the Windows Run dialog or the Apple macOS Terminal app, and running it. The Slovak cybersecurity company said the highest volume of ClickFix detections are concentrated around Japan, Peru, Poland, Spain, and Slovakia. The prevalence and effectiveness of this attack meth...

An Iranian state-sponsored hacking group associated with the Islamic Revolutionary Guard Corps (IRGC) has been linked to a spear-phishing campaign targeting journalists, high-profile cyber security experts, and computer science professors in Israel. "In some of those campaigns, Israeli technology and cyber security professionals were approached by attackers who posed as fictitious assistants to technology executives or researchers through emails and WhatsApp messages," Check Point said in a report published Wednesday. "The threat actors directed victims who engaged with them to fake Gmail login pages or Google Meet invitations." The cybersecurity company attributed the activity to a threat cluster it tracks as Educated Manticore , which overlaps with APT35 (and its sub-cluster APT42 ), CALANQUE, Charming Kitten, CharmingCypress, Cobalt Illusion, ITG18, Magic Hound, Mint Sandstorm (formerly Phosphorus), Newscaster, TA453, and Yellow Garuda. The advanced persist...
