Warning – 3 Popular VPN Services Are Leaking Your IP Address

Warning – 3 Popular VPN Services Are Leaking Your IP Address

Mar 15, 2018
Researchers found critical vulnerabilities in three popular VPN services that could leak users' real IP addresses and other sensitive data. VPN, or Virtual Private Network , is a great way to protect your daily online activities that work by encrypting your data and boosting security, as well as useful to obscure your actual IP address. While some choose VPN services for online anonymity and data security, one major reason many people use VPN is to hide their real IP addresses to bypass online censorship and access websites that are blocked by their ISPs. But what if when the VPN you thought is protecting your privacy is actually leaking your sensitive data and real location? A team of three ethical hackers hired by privacy advocate firm VPN Mentor revealed that three popular VPN service providers—HotSpot Shield, PureVPN, and Zenmate—with millions of customers worldwide were found vulnerable to flaws that could compromise user's privacy. The team includes applicat

Trojanized BitTorrent Software Update Hijacked 400,000 PCs Last Week

Mar 14, 2018
A massive malware outbreak that last week infected nearly half a million computers with cryptocurrency mining malware in just a few hours was caused by a backdoored version of popular BitTorrent client called MediaGet . Dubbed Dofoil (also known as Smoke Loader), the malware was found dropping a cryptocurrency miner program as payload on infected Windows computers that mine Electroneum digital coins for attackers using victims' CPU cycles. Dofoil campaign that hit PCs in Russia, Turkey, and Ukraine on 6th March was discovered by Microsoft Windows Defender research department and blocked the attack before it could have done any severe damages. At the time when Windows Defender researchers detected this attack, they did not mention how the malware was delivered to such a massive audience in just 12 hours. However, after investigation Microsoft today revealed that the attackers targeted the update mechanism of MediaGet BitTorrent software to push its trojanized version (m
Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

CredSSP Flaw in Remote Desktop Protocol Affects All Versions of Windows

CredSSP Flaw in Remote Desktop Protocol Affects All Versions of Windows

Mar 13, 2018
A critical vulnerability has been discovered in Credential Security Support Provider protocol (CredSSP) that affects all versions of Windows to date and could allow remote attackers to exploit RDP and WinRM to steal data and run malicious code. CredSSP protocol has been designed to be used by RDP (Remote Desktop Protocol) and Windows Remote Management (WinRM) that takes care of securely forwarding credentials encrypted from the Windows client to the target servers for remote authentication. Discovered by researchers at Cybersecurity firm Preempt Security, the issue (CVE-2018-0886) is a logical cryptographic flaw in CredSSP that can be exploited by a man-in-the-middle attacker with Wi-Fi or physical access to the network to steal session authentication data and perform a Remote Procedure Call attack. When a client and server authenticate over RDP and WinRM connection protocols, a man-in-the-middle attacker can execute remote commands to compromise enterprise networks. "A

13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors

13 Critical Flaws Discovered in AMD Ryzen and EPYC Processors

Mar 13, 2018
Security researchers claimed to have discovered 13 critical Spectre/Meltdown -like vulnerabilities throughout AMD's Ryzen and EPYC lines of processors that could allow attackers to access sensitive data, install persistent malware inside the chip, and gain full access to the compromised systems. All these vulnerabilities reside in the secure part of the AMD's Zen architecture processors and chipsets—typically where device stores sensitive information such as passwords and encryption keys and makes sure nothing malicious is running when you start your PC. The alleged vulnerabilities are categorized into four classes—RYZENFALL, FALLOUT, CHIMERA, and MASTERKEY—and threaten wide-range of servers, workstations, and laptops running vulnerable AMD Ryzen, Ryzen Pro, Ryzen Mobile or EPYC processors. Discovered by a team of researchers at Israel-based CTS-Labs, newly disclosed  unpatched vulnerabilities defeat AMD's Secure Encrypted Virtualization (SEV) technology and could
Update Samba Servers Immediately to Patch Password Reset and DoS Vulnerabilities

Update Samba Servers Immediately to Patch Password Reset and DoS Vulnerabilities

Mar 13, 2018
Samba maintainers have just released new versions of their networking software to patch two critical vulnerabilities that could allow unprivileged remote attackers to launch DoS attacks against servers and change any other users' passwords, including admin's. Samba is open-source software (re-implementation of SMB networking protocol) that runs on the majority of operating systems available today, including Windows, Linux, UNIX, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to share network shared folders, files, and printers with Windows operating system. The denial of service vulnerability, assigned CVE-2018-1050 , affects all versions of Samba from 4.0.0 onwards and could be exploited "when the RPC spoolss service is configured to be run as an external daemon." "Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash.
