Cybersecurity researchers have detected in the wild yet another variant of the Phobos ransomware family known as  Faust . Fortinet FortiGuard Labs, which detailed the latest iteration of the ransomware, said it's being propagated by means of an infection that delivers a Microsoft Excel document (.XLAM) containing a VBA script. "The attackers utilized the Gitea service to store several files encoded in Base64, each carrying a malicious binary," security researcher Cara Lin  said  in a technical report published last week. "When these files are injected into a system's memory, they initiate a file encryption attack." Faust is the latest addition to several ransomware variants from the Phobos family, including Eking, Eight, Elbie, Devos, and 8Base. It's worth noting that Faust was  previously documented  by Cisco Talos in November 2023. The cybersecurity firm described the variant as active since 2022 and "does not target specific industries or re...

The threat actors behind the Play ransomware are estimated to have impacted approximately 300 entities as of October 2023, according to a new joint cybersecurity advisory from Australia and the U.S. "Play ransomware actors employ a double-extortion model, encrypting systems after exfiltrating data and have impacted a wide range of businesses and critical infrastructure organizations in North America, South America, Europe, and Australia," authorities  said . Also called Balloonfly and PlayCrypt, Play emerged in 2022, exploiting security flaws in Microsoft Exchange servers (CVE-2022-41040 and CVE-2022-41082) and Fortinet appliances (CVE-2018-13379 and CVE-2020-12812) to breach enterprises and deploy file-encrypting malware. It's worth pointing out that ransomware attacks are increasingly exploiting vulnerabilities rather than using phishing emails as initial infection vectors, jumping from nearly zero in the second half of 2022 to almost a third in the first half of 20...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Looking for ways to unlock and read the content of an encrypted PDF without knowing the password? Well, that's now possible, sort of—thanks to a novel set of attacking techniques that could allow attackers to access the entire content of a password-protected or encrypted PDF file, but under some specific circumstances. Dubbed PDFex , the new set of techniques includes two classes of attacks that take advantage of security weaknesses in the standard encryption protection built into the Portable Document Format, better known as PDF. To be noted, the PDFex attacks don't allow an attacker to know or remove the password for an encrypted PDF; instead, enable attackers to remotely exfiltrate content once a legitimate user opens that document. In other words, PDFex allows attackers to modify a protected PDF document, without having the corresponding password, in a way that when opened by someone with the right password, the file will automatically send out a copy of the decry...

Microsoft has introduced a new password-protected folder within its OneDrive online file storage service that will allow you to keep your sensitive and important files protected and secured with an extra layer of authentication. Dubbed Personal Vault , the new OneDrive folder can only be accessed with an additional step of identity verification, such as your fingerprint, face, PIN, or a two-factor authentication code sent to you via email or SMS. The Personal Vault folder will appear next to other folders in the OneDrive app like your Documents and Pictures, but it will be locked and prompt you for an additional code each time you try to access them via the web, PC, or mobile devices, thus keeping them more secure in the event when someone gains access to your account or your device. Microsoft suggests this new protected area in OneDrive would be useful for users to store more sensitive and personal files like copies of passport, tax, car or home documents, identification cards,...

Cybersecurity researchers have released an updated version of GandCrab ransomware decryption tool that could allow millions of affected users to unlock their encrypted files for free without paying a ransom to the cybercriminals. GandCrab is one of the most prolific families of ransomware to date that has infected over 1.5 million computers since it first emerged in January 2018. Created by BitDefender, the new GandCrab decryption tool [ download ] can now unlock files encrypted by the latest versions of the ransomware, from 5.0 to 5.2, as well as for the older GandCrab ransomware versions. As part of the " No More Ransom " Project, BitDefender works in partnership with the FBI, Europol, London Police, and several other law enforcement agencies across the globe to help ransomware affected users. The cybersecurity company in recent months released ransomware removal tools for some older GandCrab versions that helped nearly 30,000 victims recover their data for free,...

Mozilla has made it easy for you to share large files securely and privately with whomever you want, eliminating the need to depend upon less secure free third-party services or file upload tools that burn a hole in your pocket. Mozilla has finally launched its free, end-to-end encrypted file-transfer service, called Firefox Send , to the public, allowing users to securely share large files like video, audio or photo files that can be too big to fit into an email attachment. Firefox Send was initially rolled out by Mozilla to test users way back in August 2017 as part of the company's now-defunct "Test Pilot" experimental program. Firefox Send allows you to send files up to 1GB in size, but if you sign up for a free Firefox account, you can upload files as large as 2.5GB in size. The service uses a browser-based encryption technology that encrypts your files before uploading them to the Mozilla server, which can only be decrypted by the recipients. Unlike popul...

Google has launched a new encryption algorithm that has been built specifically to run on mobile phones and smart IoT devices that don't have the specialized hardware to use current encryption methods to encrypt locally stored data efficiently. Encryption has already become an integral part of our everyday digital activities. However, it has long been known that encryption is expensive, as it causes performance issues, especially for low-end devices that don't have hardware support for making the encryption and decryption process faster. Since data security concerns have recently become very important, not using encryption is no more a wise tradeoff, and at the same time, using a secure but slow device on which apps take much longer to launch is also not a great idea. Currently Android OS supports AES-128-CBC-ESSIV for full-disk encryption and AES-256-XTS for file-based encryption, and Google has already made it mandatory for device manufacturers to include AES encry...

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...

In an effort to secure users' data while maintaining privacy, Google has announced a new security measure for Android Backup Service that now encrypts all your backup data stored on its cloud servers in a way that even the company can't read it. Google allows Android users to automatically backup their essential app data and settings to their Google account, allowing them to simply restore it when required, instead of re-configuring all the apps after formatting or switching to a new phone. However, until now your backup data was not encrypted and visible to Google, and now the company is going to change its storage procedure. Starting with Android Pie, Google is going to encrypt your Android device backup data in the following way: Step 1: Your Android device will generate a random secret key (not known to Google), Step 2: The secret key will then get encrypted using your lockscreen PIN/pattern/passcode (not known to Google), Step 3: This passcode-protected ...

The official Chrome extension for the MEGA.nz cloud storage service had been compromised and replaced with a malicious version that can steal users' credentials for popular websites like Amazon, Microsoft, Github, and Google, as well as private keys for users' cryptocurrency wallets. On 4 September at 14:30 UTC, an unknown attacker managed to hack into MEGA's Google Chrome web store account and upload a malicious version 3.39.4 of an extension to the web store, according to a blog post published by the company. Malicious MEGA Chrome Extension Steals Passwords Upon installation or auto-update, the malicious extension asked for elevated permissions to access personal information, allowing it to steal credentials from sites like Amazon, Github, and Google, along with online wallets such as MyEtherWallet and MyMonero, and Idex.market cryptocurrency trading...

Security researchers have spotted the first-ever ransomware exploiting Process Doppelgänging , a new fileless code injection technique that could help malware evade detection. The Process Doppelgänging attack takes advantage of a built-in Windows function, i.e., NTFS Transactions, and an outdated implementation of Windows process loader, and works on all modern versions of Microsoft Windows OS, including Windows 10. Process Doppelgänging attack works by using NTFS transactions to launch a malicious process by replacing the memory of a legitimate process, tricking process monitoring tools and antivirus into believing that the legitimate process is running. If you want to know more about how Process Doppelgänging attack works in detail, you should read this article  I published late last year. Shortly after the Process Doppelgänging attack details went public, several threat actors were found abusing it in an attempt to bypass modern security solutions. Security researc...

Ransomware has been around for a few years but has become an albatross around everyone's neck—from big businesses and financial institutions to hospitals and individuals worldwide—with cyber criminals making millions of dollars. In just past few months, we saw a scary strain of ransomware attacks including WannaCry , Petya and LeakerLocker , which made chaos worldwide by shutting down hospitals, vehicle manufacturing, telecommunications, banks and many businesses. Before WannaCry and Petya , the infamous Mamba full-disk-encrypting ransomware and the Locky ransomware had made chaos across the world last year, and the bad news is—they are back with their new and more damaging variants than ever before. Diablo6: New Variant of Locky Ransomware First surfaced in early 2016, Locky has been one of the largest distributed ransomware infections, infecting organisations across the globe. By tricking victims into clicking on a malicious attachment, Locky ransomware encrypt...

Macintosh computers are often considered to be safer than those running Windows operating system, but a recently discovered attack technique proves it all wrong. All an attacker needs is a $300 device to seize full control of your Mac or MacBook. Swedish hacker and penetration tester Ulf Frisk has developed a new device that can steal the password from virtually any Mac laptop while it is sleeping or even locked in just 30 seconds, allowing hackers to unlock any Mac computer and even decrypt the files on its hard drive. So, next time when you leave your Apple's laptop unattended, be sure to shut it down completely rather than just putting the system in sleep mode or locked. Here's How an Attacker can steal your Mac FileVault2 Password The researcher devised this technique by exploiting two designing flaws he discovered last July in Apple's FileVault2 full-disk encryption software. The first issue is that the Mac system does not protect itself against Direc...

Hackers have obtained credentials for more than 68 Million accounts for online cloud storage platform Dropbox from a known 2012 data breach. Dropbox has confirmed the breach and already notified its customers of a potential forced password resets, though the initial announcement failed to specify the exact number of affected users. However, in a selection of files obtained through sources in the database trading community and breach notification service Leakbase , Motherboard found around 5GB of files containing details on 68,680,741 accounts, which includes email addresses and hashed (and salted) passwords for Dropbox users. An unnamed Dropbox employee verified the legitimacy of the data. Out of 68 Million, almost 32 Million passwords are secured using the strong hashing function " BCrypt , " making difficult for hackers to obtain users' actual passwords, while the rest of the passwords are hashed with the SHA-1 hashing algorithm . These password hashes als...

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 al...

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...
