When I say Ransomware, the first nasty piece of malware strikes in the mind is CryptoLocker . A nasty strain of ransomware malware that threatened most of the people around the world by effectively destroying important files of the victims forever. CRYPTOLOCKER - A DEVASTATING THREAT CryptoLocker is a simple rather a devastating piece of Ransomware that encrypts the files on a victim's computer and issues an ultimatum - Pay up or lose your data. CryptoLocker is particularly designed to extort money from computer users by holding computer files hostage until the computer user pays a ransom fee to get them back. Cryptolocker hijacker sniffs out your personal files and wraps them with strong AES-256-bit encryption before it demands money. HOW TO DECRYPT CRYPTOLOCKER? FREE TOOL RELEASED Thanks to security experts, who created an online service where victims whose systems have been encrypted by the CryptoLocker ransomware can get the decryption keys for free. This o...

In this Internet savvy generation, we want all of our data to be secured at some place. Having backups of your data is always a good idea, whether that data is stored in the Cloud or on your computer. But everyone who is following the Edward Snowden leaks of the NSA 's PRISM program now pushed to hardening their Mobile devices and computers for security, privacy, and anonymity. There are many Free Cloud storage providers including  Google Drive ,  Dropbox, Box, RapidShare, Amazon Cloud Drive, Microsoft SkyDrive  and many more. These services have a limitation that all data is unencrypted, or even if it is encrypted, the encryption keys are still generated by the company's software, meaning the company still has an access to your data. So as an end user, we must think about the security and privacy of our data. We should first encrypt our files on the system level and then upload a copy of it on the cloud storage. For this a robust and highly user friendly tool called...

Cybersecurity researchers have discovered severe cryptographic issues in various end-to-end encrypted (E2EE) cloud storage platforms that could be exploited to leak sensitive data. "The vulnerabilities range in severity: in many cases a malicious server can inject files, tamper with file data, and even gain direct access to plaintext," ETH Zurich researchers Jonas Hofmann and Kien Tuong Truong said . "Remarkably, many of our attacks affect multiple providers in the same way, revealing common failure patterns in independent cryptographic designs." The identified weaknesses are the result of an analysis of five major providers such as Sync, pCloud, Icedrive, Seafile, and Tresorit. The devised attack techniques hinge on a malicious server that's under an adversary's control, which could then be used to target the service providers' users. A brief description of the flaws uncovered in the cloud storage systems is as follows - Sync, in which a maliciou...

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...

Hit by Jaff Ransomware? Don't pay the Ransom. You can unlock your files for Free! Kaspersky Labs has released an updated version 1.21.2.1 of its free ransomware decryption tool, RakhniDecryptor, which can now also decrypt files locked by the Jaff ransomware . Security researchers at Kaspersky Labs have discovered a weakness in the Jaff ransomware code that makes it possible for victims to unlock their Jaff-infected files for free. First identified last month, Jaff is relatively new ransomware that's being distributed with the help of ' Necurs botnet ' that currently controls over 6 million infected computers worldwide. Necurs botnet is the same botnet – army of compromised internet connected devices – that was used to distribute Dridex Banking Trojan and Locky ransomware , which also infects users' machines, encrypt files and then demand a ransom before unlocking them. Jaff ransomware (Trojan-Ransom.Win32.Jaff) attack is primarily carried out by sending ...

The threat actor known as ToddyCat has been observed adopting new methods to obtain access to corporate email data belonging to target companies, including using a custom tool dubbed TCSectorCopy. "This attack allows them to obtain tokens for the OAuth 2.0 authorization protocol using the user's browser, which can be used outside the perimeter of the compromised infrastructure to access corporate mail," Kaspersky said in a technical breakdown. ToddyCat, assessed to be active since 2020, has a track record of targeting various organizations in Europe and Asia with various tools, Samurai and TomBerBil to retain access and steal cookies and credentials from web browsers like Google Chrome and Microsoft Edge. Earlier this April, the hacking group was attributed to the exploitation of a security flaw in ESET Command Line Scanner (CVE-2024-11859, CVSS score: 6.8) to deliver a previously undocumented malware codenamed TCESB.  Kaspersky said it detected in attacks that ...

CryptoLocker is an especially insidious form of Ransomeware malware that was first detected in the wild in September 2013, restricts access to infected computers and requires victims to pay a ransom in order to regain full access. What makes CryptoLocker so bad is the way it encrypts the user data on your hard drive using a strong encryption method. This makes it literally impossible to access your own data without paying the ransom amount to the criminals between $100 and $300 or two  Bitcoins , even now more. Once affected you will be locked out of your computer and unless you pay the ransom amount in 72 hours , the virus will delete the decryption key to decrypt all the files on your PC . The malware lands on PCs the same way other malware does and a few sensible precautions will help minimize the chances of a CrytoLocker attack. Yesterday, we reported that - UK's National Crime Agency has given out an urgent national alert that a mass spamming event target...

The cybersecurity world is constantly evolving to new forms of threats and vulnerabilities. But ransomware proves to be a different animal—most destructive, persistent, notoriously challenging to prevent, and is showing no signs of slowing down. Falling victim to a ransomware attack can cause significant data loss, data breach, operational downtime, costly recovery, legal consequences, and reputational damage. In this story, we have covered everything you need to know about ransomware and how it works. What is ransomware? Ransomware is a malicious program that gains control over the infected device, encrypts files, and blocks user access to the data or a system until a sum of money, or ransom, is paid. Crooks' scheme includes a ransom note—with amount and instructions on how to pay a ransom in return for the decryption key—or direct communication with the victim. While ransomware impacts businesses and institutions of every size and type, attackers often target healthcare, e...

What you'll do if Ransomware infects you? Should you pay or not to recover your files? Believe me, the FBI advises - Pay off the criminals to get your files back if you don't have a backup. But paying off a ransom to cyber criminals is definitely not a wise option because there is no guarantee that you'll get the decryption key in return. In the latest incident, the new variant of KillDisk ransomware has been found encrypting Linux machines, making them unbootable with data permanently lost. What is KillDisk? KillDisk is a destructive data wiping malware that has previously been used to sabotage companies by randomly deleting files from the computers. KillDisk is the same component associated with the Black Energy malware that was used to hit several Ukrainian power stations in 2015, cutting power for thousands of people. But according to ESET security researchers, the nasty KillDisk disk wiper malware is back with new variants that target Windows and Lin...

A security researcher has compiled a ransomware removal and rescue kit to help victims deal with ransomware threats and unlock encrypted files without paying off a single penny to the cyber crooks. Ransomware is a growing threat to the evolution of cyber criminals techniques in an attempt to part you from your money. Typically, the malicious software either lock victim's computer system or encrypt the documents and files on it or in some cases both, to extort money from victims. Most often ransomware victims end up paying off crooks either due to the threat of losing their important files or in panic as the threat pretends to be from some government agency. Though IT professionals and security companies have been dealing and fighting back with the ransomware threats, security professional Jada Cyrus has compiled a " Ransomware Rescue Kit "  or "Ransomware Removal Kit"  and made it available for free online.
