Bitdefender Releases Free Decryptor for MortalKombat Ransomware Strain

Bitdefender Releases Free Decryptor for MortalKombat Ransomware Strain

Feb 28, 2023 Ransomware / Malware
Romanian cybersecurity company Bitdefender has  released  a free universal decryptor for a nascent file-encrypting malware known as MortalKombat . MortalKombat is a new ransomware strain that emerged in January 2023. It's based on a commodity ransomware dubbed Xorist and has been observed in attacks targeting entities in the U.S., the Philippines, the U.K., and Turkey. Xorist , detected since 2010, is distributed as a ransomware builder, allowing cyber threat actors to create and customize their own version of the malware. This includes the ransom note, the file name of the ransom note, the list of file extensions targeted, the wallpaper to be used, and the extension to be used on encrypted files. A decryptor for Xorist was made available by Emsisoft in May 2016. MortalKombat notably was deployed in recent attacks mounted by an unnamed financially motivated threat actor as a part of a phishing campaign aimed at a wide range of organizations. "MortalKombat encrypts vari...

Ransomware Hits Dental Data Backup Service Offering Ransomware Protection

Aug 30, 2019
THIS WEEK IN THE IRONIC NEWS: DDS Safe, an online cloud-based data backup system that hundreds of dental practice offices across the United States are using to safeguard medical records and other information of their patients from ransomware attacks has been hit with ransomware. Provided by two Wisconsin-based companies, Digital Dental Record and PerCSoft, the backend system of affected medical records retention and backup solutions has probably been hit by Sodinokibi ransomware , also known as Sodin or REvil malware. Though it's not yet clear how attackers managed to compromise the company's infrastructure, the latest ransomware attack is yet another example of successful supply chain attack, crippling computer systems in 400 dental practice offices around the United States this week. According to statements released by both companies, the ransomware virus hit a remote data management software on Monday, August 26, that DDS Safe uses to back up its client data and ...
Cyber Story Time: The Boy Who Cried "Secure!"

Cyber Story Time: The Boy Who Cried "Secure!"

Nov 21, 2024Threat Detection / Pentesting
As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic
A New Ransomware Is Targeting Network Attached Storage (NAS) Devices

A New Ransomware Is Targeting Network Attached Storage (NAS) Devices

Jul 10, 2019
A new ransomware family has been found targeting Linux-based Network Attached Storage (NAS) devices made by Taiwan-based QNAP Systems and holding users' important data hostage until a ransom is paid, researchers told The Hacker News. Ideal for home and small business, NAS devices are dedicated file storage units connected to a network or through the Internet, which allow users to store and share their data and backups with multiple computers. Independently discovered by researchers at two separate security firms, Intezer and Anomali, the new ransomware family targets poorly protected or vulnerable QNAP NAS servers either by brute forcing weak SSH credentials or exploiting known vulnerabilities. Dubbed " QNAPCrypt " by Intezer and " eCh0raix " by Anomali, the new ransomware is written in the Go programming language and encrypts files with targeted extensions using AES encryption and appends .encrypt extension to each. However, if a compromised NAS devic...

PyLocky Ransomware Decryption Tool Released — Unlock Files For Free

PyLocky Ransomware Decryption Tool Released — Unlock Files For Free

Jan 11, 2019
If your computer has been infected with PyLocky Ransomware and you are searching for a free ransomware decryption tool to unlock or decrypt your files—your search might end here. Security researcher Mike Bautista at Cisco's Talos cyber intelligence unit have released a free decryption tool that makes it possible for victims infected with the PyLocky ransomware to unlock their encrypted files for free without paying any ransom. The decryption tool works for everyone, but it has a huge limitation—to successfully recover your files, you must have captured the initial network traffic (PCAP file) between the PyLocky ransomware and its command-and-control (C2) server, which generally nobody purposely does. This is because the outbound connection—when the ransomware communicates with its C2 server and submit decryption key related information—contains a string that includes both Initialization Vector (IV) and a password, which the ransomware generates randomly to encrypt the file...
WannaCry Ransomware Decryption Tool Released; Unlock Files Without Paying Ransom

WannaCry Ransomware Decryption Tool Released; Unlock Files Without Paying Ransom

May 19, 2017
If your PC has been infected by WannaCry – the ransomware that wreaked havoc across the world last Friday – you might be lucky to get your locked files back without paying the ransom of $300 to the cyber criminals. Adrien Guinet, a French security researcher from Quarkslab, has discovered a way to retrieve the secret encryption keys used by the WannaCry ransomware for free, which works on Windows XP, Windows 7, Windows Vista, Windows Server 2003 and 2008 operating systems. WannaCry Ransomware Decryption Keys The WannaCry's encryption scheme works by generating a pair of keys on the victim's computer that rely on prime numbers, a "public" key and a "private" key for encrypting and decrypting the system's files respectively. To prevent the victim from accessing the private key and decrypting locked files himself, WannaCry erases the key from the system, leaving no choice for the victims to retrieve the decryption key except paying the ransom to ...
Botnet Sending 5 Million Emails Per Hour to Spread Jaff Ransomware

Botnet Sending 5 Million Emails Per Hour to Spread Jaff Ransomware

May 12, 2017
A massive malicious email campaign that stems from the Necurs botnet is spreading a new ransomware at the rate of 5 million emails per hour and hitting computers across the globe. Dubbed "Jaff," the new file-encrypting ransomware is very similar to the infamous Locky ransomware in many ways, but it is demanding 1.79 Bitcoins (approx $3,150), which much higher than Locky, to unlock the encrypted files on an infected computer. According to security researchers at Forcepoint Security Lab, Jaff ransomware, written in C programming language, is being distributed with the help of Necurs botnet that currently controls over 6 million infected computers worldwide. Necurs botnet is sending emails to millions of users with an attached PDF document, which if clicked, opens up an embedded Word document with a malicious macro script to downloads and execute the Jaff ransomware, Malwarebytes says . Jaff is Spreading at the Rate of 5 Million per Hour The malicious email camp...

This Ransomware Unlocks Your Files For Free If You Read CyberSecurity Articles

Jan 05, 2017
Ransomware has been around for a few years, but in last two years, it has become one of the fastest growing threats to businesses and users across the world, so will be in 2017. Ransomware is a piece of malware that encrypts files on your computer with strong encryption algorithms and then demands a ransom money in Bitcoin to decrypt the data so you can regain access to your encrypted files. We have seen some nastier ransomware infections over the past couple of years. The most interesting one was Popcorn Time that decrypts victims files for free if they pass the infection on to other people. Now, a new strain of ransomware takes the infection to a whole new level of craziness. Dubbed Koolova , the ransomware will restore your encrypted files for free, just like Popcorn Time. The only difference between both the infections is that you don't have to infect others to get free decryption key. Instead, all you have to do is educate yourself about ransomware by reading two...

Europol and IT Security Companies Team Up to Combat Ransomware Threat

Jul 25, 2016
No More Ransom, so is the Ransomware Threat. The European Police agency Europol has joined forces with police and cyber security companies to launch a worldwide initiative to combat and tackle together the exponential growth of Ransomware used by cyber criminals. Europol announced today the initiative, dubbed NO More Ransom, that has been backed by technology giant Intel, cyber security firm Kaspersky Lab and the Netherlands police, aiming at decreasing an "exponential" rise in Ransomware threat. Ransomware is a piece of malware that typically locks victim's device using encryption and demands a fee to decrypt the important data. The estimated number of ransomware victims tripled in the first quarter of this year alone. "For a few years now ransomware has become a dominant concern for EU law enforcement," said Europol's deputy director Wil van Gemert. "We expect to help many people to recover control over their files, while raising awareness...
