What's the worst that could happen when a Ransomware malware hits University? Last month, the IT department of the University from where I have done my graduation called me for helping them get rid of a Ransomware infection that locked down all its student's results just a day before the announcement. Unfortunately, there was no decrypter available for that specific ransomware sample, but luckily they had the digital backup for the examination results in the form of hundreds of excel sheets. So, somehow backup helped administrator to re-compile complete result once again into the database, but this delayed the announcement for over 30 days. However, the situation is not same every time. Recently, the University of Calgary in Alberta  paid a ransom of $20,000 to decrypt their computer systems' files and regain access to its own email system after getting hit by a ransomware infection. The University fell victim to ransomware last month, when the malware instal

Here's some good news for victims who are trying to unlock and remove TeslaCrypt ransomware. Now, you can decrypt all your important files that have been encrypted by TeslaCrypt ransomware. So, stop Googling about How to decrypt TeslaCrypt Ransomware encrypted files, as the malware authors themselves provided the solution to your problem. Since its launch in March last year, TeslaCrypt computer virus has been used in massive malvertising attacks. The ransomware, which often targets PC gamers, locks up files until a ransom is paid, usually $500 in Bitcoin. Infection generally comes through corrupted websites, malvertising or phishing emails. In a surprising move in the malware's story, the cybercriminals behind the nefarious TeslaCrypt ransomware have apparently shut down their operations and released a master key to the public that can unlock all encrypted files on PCs infected by the latest versions of TeslaCrypt. The icing on the cake is that the universal decryption

Ransomware has become an albatross around the neck, targeting businesses, hospitals , and personal computers worldwide and extorting Millions of Dollars . Typical Ransomware targets victim's computer encrypts files on it, and then demands a ransom -- typically about $500 in Bitcoin -- in exchange for a key that will decrypt the files. Guess what could be the next target of ransomware malware? Everything that is connected to the Internet. There is a huge range of potential targets, from the pacemaker to cars to Internet of the Things, that may provide an opportunity for cybercriminals to launch ransomware attacks. Recently, the American public utility Lansing Board of Water & Light (BWL) has announced that the company has become a victim of Ransomware attack that knocked the utility's internal computer systems offline.

Permissions in SaaS platforms like Salesforce, Workday, and Microsoft 365 are remarkably precise. They spell out exactly which users have access to which data sets. The terminology differs between apps, but each user's base permission is determined by their role, while additional permissions may be granted based on tasks or projects they are involved with. Layered on top of that are custom permissions required by an individual user.  For example, look at a sales rep who is involved in a tiger team investigating churn while also training two new employees. The sales rep's role would grant her one set of permissions to access prospect data, while the tiger team project would grant access to existing customer data. Meanwhile, special permissions are set up, providing the sales rep with visibility into the accounts of the two new employees. While these permissions are precise, however, they are also very complex. Application admins don't have a single screen within these applications th

In Brief: Introducing  RansomWhere , a free generic ransomware detection tool for Mac OS X users that can identify ransomware-like behavior by continually monitoring the file-system for the creation of encrypted files by suspicious processes. This ransomware detection tool helps to block the suspicious processes and waits for the user to decide whether to allow or stop the process. Ransomware has risen dramatically since last few years... so rapidly that it might have already hit someone you know. With hundred of thousands of ransomware samples emerging every day, it is quite difficult for traditional signature-based antivirus products to keep their signature database up-to-date. So, if signature-based techniques are not enough to detect ransomware infection , then what else can we do? Some Antivirus companies have already upgraded their security solutions that detect suspicious behaviors like the sequential accessing of a large number of files, using encryption algori

Ransomware has risen dramatically since last few years and is currently one of the most popular threats on the Internet. The Ransomware infections have become so sophisticated with the time that victims end up paying ransom in order to get their critical and sensitive data back. But if you are infected with Petya Ransomware , there is good news for you. You can unlock your infected computer without paying the hefty ransom. Thanks to the Petya author who left a bug in the Ransomware code. What is Petya Ransomware? Petya is a nasty piece of ransomware that emerged two weeks ago and worked very differently from any other ransomware. The ransomware targets the victims by rebooting their Windows computers, encrypting the hard drive's master boot file, and rendering the master boot record inoperable.

Do you deal with MS Word files on the daily basis? If yes, then are you aware that even opening a simple doc file could compromise your system? It is a matter to think that the virus does not directly affect you, but it is you who let the virus carry out the attack by enabling deadly "Macros" to view the doc contents that are generally on eye-catching subjects like bank invoice. How Macros are Crippling your System? The concept of Macros dates back to 1990s. You must be familiar with this message: " Warning: This document contains macros. " A Macro is a series of commands and actions that help to automate some tasks. Microsoft Office programs support Macros written in Visual Basic for Applications (VBA), but they can also be used for malicious activities like installing malware. Hackers are cleverly using this technique on the shade of social engineering by sending the malicious Macros through doc file or spreadsheet with an eye-catching subject in t

Hackers are always in search for an elite method to create loopholes in the cyberspace to implement the dark rules in the form of vulnerability exploitation. Top Trustworthy sites such as The New York Times , BBC , MSN , AOL and many more are on the verge of losing their face value as a malwertized advertisement campaign are looming around the websites, according to SpiderLabs. Here's what Happens to Users when Clicking Ads on these Big Brand Sites: The advertisements on the legit sites trick users into clicking on it, making them believe that these circulated ads come from a trusted networks. Once clicked, the malicious Ad redirects the user to a malicious website that hosts Angler Exploit Kit (AEK) to infect visitors by installing malware and ransomware on their computer. Angler Exploit Kit includes many malicious hacking tools and zero-day exploits that let hackers execute drive-by attacks on visitors' computers. In this case, the Angler kit scan

In last few years, we saw an innumerable rise in ransomware threats ranging from Cryptowall to Locky ransomware discovered last week. Now, another genre of ransomware had been branched out from the family of CTB-Locker Ransomware with an update to infect Websites. The newly transformed ransomware dubbed " CTB-Locker for Websites " exclusively hijacks the websites by locking out its data, which would only be decrypted after making a payment of 0.4 BTC. This seems to be the very first time when any ransomware has actually defaced a website in an attempt to convince its administrator to comply with the ransom demand. However, the infected website admins can unlock any 2 files by the random generator for free as a proof of decryption key works. Here's How CTB-Locker for Websites Ransomware Works Lawrence explained that CTB-Locker ransomware replaces the index page ( the original index.php or index.html ) of the servers hosting websites with the

If you receive a mail masquerading as a company's invoice and containing a Microsoft Word file, think twice before clicking on it. Doing so could cripple your system and could lead to a catastrophic destruction. Hackers are believed to be carrying out social engineering hoaxes by adopting eye-catching subjects in the spam emails and compromised websites to lure the victims into installing a deadly ransomware, dubbed " Locky ," into their systems. So if you find .locky extension files on your network shares, Congratulations! You are infected and left with just two solutions: Rebuild your PC from scratch or Pay the ransom. Locky ransomware is spreading at the rate of 4000 new infections per hour , which means approximately 100,000 new infections per day . Microsoft MACROS are Back It is hard to digest the fact that, in this 2016, even a single MS Word document could compromise your system by enabling ' Macros .' This is where the poin

Ransomware has seriously turned on to a noxious game of Hackers to get paid effortlessly. Once again the heat was felt by the Los Angeles-based Presbyterian Medical Center when a group of hackers had sealed all its sensitive files and demanded $17,000 USD to regain the access to those compromised data. The devastation of the compromised files can be pitched as: Compromised emails Lockout Electronic Medical Record System [EMR] Encrypted patient data Unable to carry CT Scans of the admitted patients Ferried risky patients to nearby hospitals ...and much more unexplained outcomes. The hospital had confirmed that the Ransomware malware had hit its core heart a week before, potentially affecting the situation to grow much worse. Hospital End up Paying $17,000 As the situation was grown out of wild, the hospital paid 40 Bitcoins (Roughly US $17,000) to the Ransomware Criminals to resume their medical operations after gaining the decryption keys. "T

Over the last few years, we have seen several types of Ransomware malware that demand a whopping amount of money from users for the retrieval of their locked, compromised sensitive files. We have also witnessed the birth of decryption solution for some of the Ransomware like Cryptolocker (partial), Coinvault , Rescue Kit . One more solution has recently been released for decryption of newly emerging ransomware, dubbed as Hydracrypt and Umbrecrypt that are propagated through Angler Exploit Kit. Both of the malware belong to CrypBoss ransomware family. The source code of CrypBoss Ransomware was leaked last year on Pastebin, which was later analyzed by Fabian Wosar, a security researcher at Emsisoft. With the help of CrypBoss Source code, Wosar was successfully able to crack the encryption algorithm of the ransomware and quickly made the decryption tool for CrypBoss and its variants ( Hydracrypt and Umbrecrypt ). It is found that both Hydracrypt and Umbrec

Ransomware is now a common practice for money-motivated cyber criminals. It's basically a type of software written in any system-based programming language that has the ability to hijack victim's computer, encrypts files and then ask for a ransom amount to get them back. One such ransomware dubbed Linux.Encoder targets Linux-powered websites and servers by encrypting MySQL, Apache, and home/root folders associated with the target site and asks for 1 Bitcoin ( $453.99 ) to decrypt those crucial files. But, the good news is it is very easy to get rid of it. The Malware author released the third version of the Linux.Encoder ransomware, which security researchers from Bitdefender have managed to crack, yet again, after breaking previous two versions. However, before the team managed to release the Linux.Encoder decryption tool, the third iteration of Linux.Encoder ransomware, which was first discovered by antivirus maker Dr.Web, has infected a nearly 600 servers w

Here's New Year's first Ransomware: Ransom32 . A new Ransomware-as-a-service, dubbed Ransom32 , has been spotted that for the first time uses a ransomware written in JavaScript to infect Mac, Windows as well as Linux machines. Ransom32 allows its operators to deploy the malware very quickly and easily. It has a dashboard that enables operators to designate their Bitcoin addresses to which the ransom can be sent. The dashboard also shows stats about how much Bitcoins they have made. In short, this new ransomware-as-a-service is so simple, and efficient at the same time, that anyone can download and distribute his/her own copy of the ransomware executable as long as he/she have a Bitcoin address. The copy of Ransom32 was first analysed by Emsisoft, which found that the new ransomware family, which embedded in a self-extracting WinRAR archive, is using the NW.js platform for infiltrating the victims' computers, and then holding their files by encrypting the

You should be very careful while visiting websites on the Internet because you could be hit by a new upgrade to the World's worst Exploit Kit – Angler , which lets hackers develop and conduct their own drive-by attacks on visitors' computers with relative ease. Many poorly-secured websites are targeting Windows users with a new "Cocktail" of malware that steals users' passwords before locking them out from their machines for ransom. Yes, stealing Windows users' passwords before encrypting their data and locking their PCs for ransom makes this upgrade to the Angler Exploit Kit nastier. Here's How the New Threat Works: Once the Angler exploit kit finds a vulnerable application, such as Adobe Flash, in visitor's computer, the kit delivers its malicious payloads, according to a blog post published by Heimdal Security. The First Payload infects the victim's PC with a widely used data thief exploit known as Pony that systematic

Beware Internet Users! Cryptowall 4.0 – the newest version of the world's worst Ransomware – has surfaced in the Nuclear exploit kit , one of the most potent exploit kits available in the underground market for hacking into computers. Ransomware threat has emerged as one of the biggest threats to internet users in recent times. Typically, a Ransomware malware encrypts all files on victim's computer with a strong cryptographic algorithm, then demand a ransom to be paid in Bitcoin (range between $200 and $10,000). Cryptowall is currently among the most widespread and sophisticated family of Ransomware backed by a very robust back-end infrastructure. Also Read: Anyone can Now Create their Own Ransomware using This Hacking ToolKit The recent report dated back to last month suggested that the authors of Cryptowall 3.0 ransomware virus have managed to raise more than $325 Million in revenue in the past year alone. With the debut of Cryptowall 4.0 at the beg

Since past few years, Ransomware has emerged as one of the catastrophic malware programs that lets hacker encrypts all the contents of a victim's hard drive or/and server and demands ransom (typically to be paid in Bitcoin ) in exchange for a key to decrypt it. Until now cyber criminals were targeting computers, smartphones and tablets, but now it appears they are creating ransomware that makes the same impact but for Web Sites – specifically holding files, pages and images of the target website for Ransom. Dubbed Linux.Encoder.1 by Russian antivirus firm Dr.Web , the new strain of ransomware targets Linux-powered websites and servers by encrypting MySQL, Apache, and home/root folders associated with the target site and asking for 1 Bitcoin ( ~ $300 ) to decrypt the files. The ransomware threat is delivered to the target website through known vulnerabilities in website plugins or third-party software. Must Read: FBI Suggests Ransomware Victims — 'Just Pay th
