Hackers Exploiting Microsoft Servers to Mine Monero - Makes $63,000 In 3 Months

September 28, 2017Swati Khandelwal
Mining cryptocurrencies can be a costly investment as it takes a monstrous amount of computing power, and thus hackers have started using malware that steals computing resources of computers it hijacks to make lots of dollars in digital currency. Security researchers at security firm ESET have spotted one such malware that infected hundreds of Windows web servers with a malicious cryptocurrency miner and helped cybercriminals made more than $63,000 worth of Monero (XMR) in just three months. According to a report published by ESET today, cybercriminals only made modifications to legitimate open source Monero mining software and exploited a known vulnerability in Microsoft IIS 6.0 to secretly install the miner on unpatched Windows servers. Although ESET's investigation does not identify the attackers, it reports that the attackers have been infecting unpatched Windows web servers with the cryptocurrency miner since at least May 2017 to mine 'Monero,' a Bitcoin-like
Windows SMB Zero-Day Exploit Released in the Wild after Microsoft delayed the Patch

Windows SMB Zero-Day Exploit Released in the Wild after Microsoft delayed the Patch

February 05, 2017Swati Khandelwal
Last weekend a security researcher publically disclosed a zero-day vulnerability in Windows 10, Windows 8.1 and Server editions after Microsoft failed to patch it in the past three months. The zero-day memory corruption flaw resides in the implementation of the SMB (server message block) network file sharing protocol that could allow a remote, unauthenticated attacker to crash systems with denial of service attack, which would then open them to more possible attacks. According to US-CERT, the vulnerability could also be exploited to execute arbitrary code with Windows kernel privileges on vulnerable systems, but this has not been confirmed right now by Microsoft. Without revealing the actual scope of the vulnerability and the kind of threat the exploit poses, Microsoft has just downplayed the severity of the issue, saying: "Windows is the only platform with a customer commitment to investigate reported security issues, and proactively update impacted devices as soon as
Donald Trump's Email Servers are Horribly Insecure — Researcher Reveals

Donald Trump's Email Servers are Horribly Insecure — Researcher Reveals

October 18, 2016Swati Khandelwal
When Hillary Clinton's private email server was hacked earlier this year, she was criticized for her bad security practices that exposed top secret documents stored in emails on that private server. The FBI called her behavior 'extremely careless.' Republican presidential candidate Donald Trump and his supporters are continuously criticizing Clinton's use of a private email server. And here's what Trump lectured in a debate about cybersecurity: "The security aspect of cyber is very, very tough. And maybe it's hardly doable. But I will say, we are not doing the job we should be doing. But that's true throughout our whole governmental society. We have so many things that we have to do better, Lester, and certainly, cyber is one of them." Forget Clinton; Trump has so worryingly insecure internet setup that anyone with little knowledge of computers can expose almost everything about Trump and his campaign.

Windows Updates Can be Intercepted to Inject Malware into Corporate Networks

Windows Updates Can be Intercepted to Inject Malware into Corporate Networks

If you think that the patches delivered through Windows update can not be laced with malware, think again. Security researchers have shown that Hackers could intercept Windows Update to deliver and inject malware in organizations. Security researchers from UK-based security firm ' Context ' have discovered a way to exploit insecurely configured implementations of Windows Server Update Services (WSUS) for an enterprise. What is WSUS in Windows? Windows Server Update Services (WSUS) allows an administrator to deploy the Windows software update to servers and desktops throughout the organization. These updates come from the WSUS server and not Windows server. Once the updates are with the administrator on the server, he can limit the privilege for the clients in a corporate environment to download and install these updates. As the admin is the owner of the distribution of these updates. Intercepting WSUS to Inject Malware into Corporate Networks By def
18-year-old Unpatched Vulnerability Affects All Versions of Microsoft Windows

18-year-old Unpatched Vulnerability Affects All Versions of Microsoft Windows

Security researchers have unearthed a serious security flaw in all supported versions of Windows that could let hackers steal users' credentials from computers, tablets or servers running any version of Windows operating system, including the as-yet-released Windows 10. This vulnerability in Windows was first discovered 20 Years ago : The critical bug, dubbed " Redirect to SMB ," is a variant of a vulnerability found in Windows by researcher Aaron Spangler nearly 18 years ago that caused Windows to expose a user's Windows username and password automatically. However, according to researchers at security firm Cylance who discovered the flaw, this weakness in Windows was never patched by Microsoft, as Microsoft says that this flaw is not worth focusing on, and, therefore... ...This results in a new hack that targets the SMB file sharing protocol . But, What is SMB? SMB, or Server Message Block, is a protocol that allows users to share files o

While the whole world was waiting for the next generation of Windows operating system , i.e. Windows 9, but skipping right over 9, Microsoft has announced the next version of its Windows is Windows 10 , disclosing its first details on Tuesday at an event in San Francisco. The latest version of Microsoft's flagship operating system, which will be available for everyone next year, brings back the popular Start Menu, which had been removed from Windows 8. Windows 10 will be Microsoft's single platform for developing apps across all devices, from Smartphones and tablets to desktop PCs. However, Windows 10 will not be a one-size-fits-all operating system and instead will vary a bit from device to device. " Windows 10 will run on the broadest amount of devices. A tailored experience for each device ," Microsoft's executive VP of operating systems, Terry Myerson said at a press event here Tuesday. " There will be one way to write a universal application, one
