JackFix Uses Fake Windows Update Pop-Ups on Adult Sites to Deliver Multiple Stealers

JackFix Uses Fake Windows Update Pop-Ups on Adult Sites to Deliver Multiple Stealers

Nov 25, 2025 Windows Security / Malvertising
Cybersecurity researchers are calling attention to a new campaign that's leveraging a combination of ClickFix lures and fake adult websites to deceive users into running malicious commands under the guise of a "critical" Windows security update. "Campaign leverages fake adult websites (xHamster, PornHub clones) as its phishing mechanism, likely distributed via malvertising," Acronis said in a new report shared with The Hacker News. "The adult theme, and possible connection to shady websites, adds to the victim's psychological pressure to comply with sudden 'security update' installation." ClickFix-style attacks have surged over the past year, typically tricking users into running malicious commands on their own machines using prompts for technical fixes or completing CAPTCHA verification checks. According to data from Microsoft, ClickFix has become the most common initial access method, accounting for 47% of attacks. The latest camp...
Microsoft Plans to Add Secure Shell (SSH) to Windows

Microsoft Plans to Add Secure Shell (SSH) to Windows

Jun 03, 2015
Until now Unix and Linux system administrators have to download a third-party SSH client software like Putty on their Windows machines to securely manage their machines and servers remotely through Secure Shell protocol or Shell Session (better known as SSH ). This might have always been an awkward feature of Windows platform, as it lacks both – a native SSH client software for connecting to Linux machines, and an SSH server to support inbound connections from Linux machines. But… Believe it or not: You don't need to deal with any third-party SSH client now, as Microsoft is working on supporting OpenSSH. Yes, Microsoft has finally decided to bring OpenSSH client and server to Windows. The PowerShell team at Microsoft has announced that the company is going to support and contribute to OpenSSH community in an effort to deliver better SSH support in the PowerShell and Windows SSH software solutions. So, the upcoming version of Windows PowerShell – the co...
Newly Patched Critical Microsoft WSUS Flaw Comes Under Active Exploitation

Newly Patched Critical Microsoft WSUS Flaw Comes Under Active Exploitation

Oct 24, 2025 Vulnerability / Network Security
Microsoft on Thursday released out-of-band security updates to patch a critical-severity Windows Server Update Services (WSUS) vulnerability with a proof-of-concept (Poc) exploit publicly available and has come under active exploitation in the wild. The vulnerability in question is CVE-2025-59287 (CVSS score: 9.8), a remote code execution flaw in WSUS that was originally fixed by the tech giant as part of its Patch Tuesday update published last week. Three security researchers, MEOW, f7d8c52bec79e42795cf15888b85cbad, and Markus Wulftange with CODE WHITE GmbH, have been acknowledged for discovering and reporting the bug. The shortcoming concerns a case of deserialization of untrusted data in WSUS that allows an unauthorized attacker to execute code over a network. It's worth noting that the vulnerability does not impact Windows servers that do not have the WSUS Server Role enabled. In a hypothetical attack scenario, a remote, unauthenticated attacker could send a crafted eve...

Commando VM — Turn Your Windows Computer Into A Hacking Machine

Commando VM — Turn Your Windows Computer Into A Hacking Machine

Mar 29, 2019
FireEye today released Commando VM , which according to the company, is a "first of its kind Windows-based security distribution for penetration testing and red teaming." When it comes to the best-operating systems for hackers, Kali Linux is always the first choice for penetration testers and ethical hackers. However, Kali is a Linux-based distribution, and using Linux without learning some basics is not everyone's cup of tea as like Windows or macOS operating systems. Moreover, if you are wondering why there is no popular Windows-based operating system for hackers? First, because Windows is not open-source and second, manually installing penetration testing tools on Windows is pretty problematic for most users. To help researchers and cyber security enthusiasts, cybersecurity firm FireEye today released  an automated installer called  Commando VM. But don't get confused with its name. Commando VM is not a pre-configured snapshot of a virtual machine ima...

Experts Warn of Stealthy PowerShell Backdoor Disguising as Windows Update

Experts Warn of Stealthy PowerShell Backdoor Disguising as Windows Update

Oct 19, 2022
Details have emerged about a previously undocumented and fully undetectable (FUD) PowerShell backdoor that gains its stealth by disguising itself as part of a Windows update process. "The covert self-developed tool and the associated C2 commands seem to be the work of a sophisticated, unknown threat actor who has targeted approximately 100 victims," Tomer Bar, director of security research at SafeBreach,  said  in a new report. Attributed to an  unnamed threat actor , attack chains involving the malware commence with a weaponized  Microsoft Word document  that, per the company, was uploaded from Jordan on August 25, 2022. Metadata associated with the lure document indicates that the initial intrusion vector is a LinkedIn-based spear-phishing attack, which ultimately leads to the execution of a PowerShell script via a piece of embedded macro code. "The Macro drops 'updater.vbs,' creates a scheduled task pretending to be part of a Windows update, which will ...

Microsoft to Remove SMBv1 Protocol in Next Windows 10 Version (RedStone 3)

Jun 20, 2017
The Server Message Block version 1 (SMBv1) — a 30-year-old file sharing protocol which came to light last month after the devastating WannaCry outbreak — will be removed from the upcoming Windows 10 (1709) Redstone 3 Update. The SMBv1 is one of the internet's most ancient networking protocols that allows the operating systems and applications to read and write data to a system and a system to request services from a server. The WannaCry ransomware , which wreaked havoc last month, was also leveraging an NSA's Windows SMB exploit, dubbed EternalBlue , leaked by the Shadow Brokers in its April data dump. The WannaCry ransomware menace shut down hospitals , telecommunication providers, and many businesses worldwide, infecting hundreds of thousands of unpatched Windows servers running SMBv1 in more than 150 countries within just 72 hours on 12th of May. Although Microsoft patched the vulnerability in SMBv1 in March in MS17-010 , the company meanwhile strongly advised us...

Cybercriminals Using PowerShell to Steal NTLMv2 Hashes from Compromised Windows

Cybercriminals Using PowerShell to Steal NTLMv2 Hashes from Compromised Windows

Sep 11, 2023 Endpoint Security / Malware
A new cyber attack campaign is leveraging the PowerShell script associated with a legitimate red teaming tool to plunder  NTLMv2 hashes  from compromised Windows systems primarily located in Australia, Poland, and Belgium. The activity has been codenamed Steal-It by Zscaler ThreatLabz. "In this campaign, the threat actors steal and exfiltrate NTLMv2 hashes using customized versions of Nishang's  Start-CaptureServer PowerShell script , executing various system commands, and exfiltrating the retrieved data via Mockbin APIs," security researchers Niraj Shivtarkar and Avinash Kumar said. Nishang  is a framework and collection of PowerShell scripts and payloads for offensive security, penetration testing, and red teaming. The attacks leverage as many as five different infection chains, although they all leverage phishing emails containing ZIP archives as the starting point to infiltrate specific targets using geofencing techniques - NTLMv2 hash stealing infection...
