Here's How to Decrypt Hydracrypt & Umbrecrypt Ransomware Files

Here's How to Decrypt Hydracrypt & Umbrecrypt Ransomware Files

Feb 13, 2016
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

FBI Suggests Ransomware Victims — 'Just Pay the Ransom Money'

Oct 27, 2015
Your Headache is not my Problem. If your computer gets hacked and infected with malware that holds your data for ransom, just pay off the criminals to see your valuable data again and do not expect the FBI to save them – it's what the FBI is advising concerning ransomware . Ransomware is a sophisticated malicious software that lets hacker encrypts all the contents of a victim's hard drive or/and server and demands ransom (typically in Bitcoins) for the decrypt key. Also Read:   Free Ransomware Decryption and Malware Removal ToolKit Federal agencies and the FBI have long urged people not to pay ransom to the criminals, as there is no guarantee that they will even receive an unlock key. The FBI – 'Better Pay up the Ransom' However, while speaking at the 2015 Cyber Security Summit on Wednesday, Assistant Special Agent Joseph Bonavolonta , who oversees the FBI's Boston office, advised the companies infected with ransomware to better pay up th

Shining a Light on Shadow Apps: The Invisible Gateway to SaaS Data Breaches

Sep 10, 2024SaaS Security / Risk Management
Shadow apps, a segment of Shadow IT, are SaaS applications purchased without the knowledge of the security team. While these applications may be legitimate, they operate within the blind spots of the corporate security team and expose the company to attackers.  Shadow apps may include instances of software that the company is already using. For example, a dev team may onboard their own instance of GitHub to keep their work separate from other developers. They might justify the purchase by noting that GitHub is an approved application, as it is already in use by other teams. However, since the new instance is used outside of the security team's view, it lacks governance. It may store sensitive corporate data and not have essential protections like MFA enabled, SSO enforced, or it could suffer from weak access controls. These misconfigurations can easily lead to risks like stolen source code and other issues. Types of Shadow Apps  Shadow apps can be categorized based on their interac
Chicago Police Department Pays $600 Cryptoware Ransom to Cybercriminals

Chicago Police Department Pays $600 Cryptoware Ransom to Cybercriminals

Feb 23, 2015
Cyber criminals have started targeting government enforcement of the Ransomware in an attempt to extort money. Recently, the police department of the Midlothian Village in Illinois has paid a ransom of over $600 in Bitcoins to an unknown hacker after being hit by a popular ransomware attack. The popular Ransomware, dubbed Cryptoware , disabled a police computer in Midlothian — located south of Chicago — by making it inaccessible through its file-encryption capabilities and forced them to pay a ransom in order to restore access to the important police records. The Chicago Tribune reported that the department first encountered Cryptoware in January, when someone in the department opened a spear-phishing email that pointed to the malicious software. Once opened, the email carrying the Cryptoware ransomware immediately encrypts the files on the computer and, in typical ransomware style, displays a message demanding money in exchange for a decrypt code that could free the

First Android Ransomware that Encrypts SD Card Files

First Android Ransomware that Encrypts SD Card Files

Jun 05, 2014
We have seen cybercriminals targeting PCs with Ransomware malware that encrypts your files or lock down your computer and ask for a ransom amount to be paid in a specified duration of time to unlock it. To deliver the Ransomware malwares to the mobile devices, cyber criminals have already started creating malicious software programs for android devices. Last month, we reported about a new Police Ransomware malware that locks up the devices until the victims pay a ransom to get the keys to unlock the phone. But, the malware just lock the mobile screen and a loophole in the its implementation allowed users to recover their device and data stored on SDcard. Now, in an effort to overcome this, threat actors have adopted encryption in the development of mobile Ransomware malwares. Recently, the security firm ESET has discovered a new Android ransomware, dubbed as Android/Simplocker.A , that has ability to encrypt the files on the device SD card and then demand a ransom from the victim
TrueCrypt is Secure; Encryption Tool cleared the First Phase of Security Audit

TrueCrypt is Secure; Encryption Tool cleared the First Phase of Security Audit

Apr 15, 2014
Is TrueCrypt Audited Yet? Yes, In Part!  One of the world's most-used open source file encryption software trusted by tens of millions of users - TrueCrypt is being audited by a team of experts to assess if it could be easily exploited and cracked. Hopefully it has cleared the first phase of the audit and given a relatively clean bill of health. TrueCrypt is a free, open-source and cross-platform encryption program available for Windows, OSX and Linux that can be used to encrypt individual folders or encrypt entire hard drive partitions including the system partition.  The program is also capable to do some amazing things, such as can create a hidden operating system on a computer, essentially an OS within an OS where users can keep their most secret files. EVERYONE HAS SOMETHING TO HIDE TrueCrypt developers are anonymous and used the aliases " ennead " and " syncon ", perhaps to avoid unwelcome attention from their own governments. But when we talk about Privacy an
