A serious vulnerability has been discovered in Microsoft-owned most popular free web messaging and voice calling service Skype that could potentially allow attackers to gain full control of the host machine by granting system-level privileges to a local, unprivileged user. The worst part is that this vulnerability will not be patched by Microsoft anytime soon. It's not because the flaw is unpatchable, but because fixing the vulnerability requires a significant software rewrite, which indicates that the company will need to issue an all-new version of Skype rather than just a patch. The vulnerability has been discovered and reported to Microsoft by security researcher Stefan Kanthak and resides in Skype's update installer, which is susceptible to Dynamic Link Libraries (DLL) hijacking. According to the researcher, a potential attacker could exploit the "functionality of the Windows DLL loader where the process loading the DLL searches for the DLL to be loaded fi

Microsoft's Patch Tuesday for this month falls the day before the most romantic day of the year. Yes, it's Valentine's, and the tech giant has released its monthly security update for February 2018, addressing a total of 50 CVE-listed vulnerabilities in its Windows operating system, Microsoft Office, web browsers and other products. Fourteen of the security updates are listed as critical, 34 are rated as important, and 2 of them are rated as moderate in severity. The critical update patches serious security flaws in Edge browser and Outlook client, an RCE in Windows' StructuredQuery component, and several memory corruption bugs in the scripting engines used by Edge and Internet Explorer. Critical Microsoft Outlook Vulnerability One of the most severe bugs includes a memory corruption vulnerability ( CVE-2018-0852 ) in Microsoft Outlook, which can be exploited to achieve remote code execution on the targeted machines.

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint . Unprotected endpoints provide vulnerable entry points to launch devastating cyberattacks. With IT teams needing to protect more endpoints—and more kinds of endpoints—than ever before, that perimeter has become more challenging to defend. You need to improve your endpoint security, but where do you start? That's where this guide comes in.  We've curated the top 10 must-know endpoint security tips that every IT and security professional should have in their arsenal. From identifying entry points to implementing EDR solutions, we'll dive into the insights you need to defend your endpoints with confidence.  1.

A zero-day vulnerability has been discovered in the desktop version for end-to-end encrypted Telegram messaging app that was being exploited in the wild in order to spread malware that mines cryptocurrencies such as Monero and ZCash. The Telegram vulnerability was uncovered by security researcher Alexey Firsh from Kaspersky Lab last October and affects only the Windows client of Telegram messaging software. The flaw has actively been exploited in the wild since at least March 2017 by attackers who tricked victims into downloading malicious software onto their PCs that used their CPU power to mine cryptocurrencies or serve as a backdoor for attackers to remotely control the affected machine, according to a blogpost on Securelist. Here's How Telegram Vulnerability Works The vulnerability resides in the way Telegram Windows client handles the RLO (right-to-left override) Unicode character (U+202E), which is used for coding languages that are written from right to left, li

The Pyeongchang Winter Olympics taking place in South Korea was disrupted over the weekend following a malware attack before and during the opening ceremony on Friday. The cyber attack coincided with 12 hours of downtime on the official website for the Winter Games, the collapse of Wi-Fi in the Pyeongchang Olympic stadium and the failure of televisions and internet at the main press center, leaving attendees unable to print their tickets for events or get venue information. The Pyeongchang Winter Olympics organizing committee confirmed Sunday that a cyber attack hit its network helping run the event during the opening ceremony, which was fully restored on 8 am local time on Saturday—that's full 12 hours after the attack began. Multiple cybersecurity firms published reports on Monday, suggesting that the cause of the disruption was "destructive" wiper malware that had been spread throughout the Winter Games' official network using stolen credentials. Dubbed

There was a time when hackers simply defaced websites to get attention, then they started hijacking them to spread banking trojan and ransomware, and now the trend has shifted towards injecting scripts into sites to mine cryptocurrencies. Thousands of government websites around the world have been found infected with a specific script that secretly forces visitors' computers to mine cryptocurrency for attackers. The cryptocurrency mining script injection found on over 4,000 websites, including those belonging to UK's National Health Service (NHS), the Student Loan Company, and data protection watchdog Information Commissioner's Office (ICO), Queensland legislation, as well as the US government's court system. Users who visited the hacked websites immediately had their computers' processing power hijacked, also known as cryptojacking, to mine cryptocurrency without their knowledge, potentially generating profits for the unknown hacker or group of hackers.
