 Albabat, Kasseika, Kuiper: New Ransomware Gangs Rise with Rust and Golang

Albabat, Kasseika, Kuiper: New Ransomware Gangs Rise with Rust and Golang

Jan 29, 2024 Ransomware / Malware
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
Double-Extortion Play Ransomware Strikes 300 Organizations Worldwide

Double-Extortion Play Ransomware Strikes 300 Organizations Worldwide

Dec 19, 2023 Ransomware / Threat Intelligence
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
Code Keepers: Mastering Non-Human Identity Management

Code Keepers: Mastering Non-Human Identity Management

Apr 12, 2024DevSecOps / Identity Management
Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or
Researchers Find New Hack to Read Content Of Password Protected PDF Files

Researchers Find New Hack to Read Content Of Password Protected PDF Files

Oct 01, 2019
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 Adds 2FA-Protected "Personal Vault" Within OneDrive Cloud Storage

Microsoft Adds 2FA-Protected "Personal Vault" Within OneDrive Cloud Storage

Jun 26, 2019
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,

Jun 18, 2019
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,
Firefox Send — Free Encrypted File Transfer Service Now Available For All

Firefox Send — Free Encrypted File Transfer Service Now Available For All

Mar 13, 2019
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 Created Faster Storage Encryption for All Low-End Devices

Google Created Faster Storage Encryption for All Low-End Devices

Feb 08, 2019
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
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
Google to Encrypt Android Cloud Backups With Your Lock Screen Password

Google to Encrypt Android Cloud Backups With Your Lock Screen Password

Oct 15, 2018
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

First-Ever Ransomware Found Using ‘Process Doppelgänging’ Attack to Evade Detection

First-Ever Ransomware Found Using 'Process Doppelgänging' Attack to Evade Detection

May 07, 2018
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 researchers

How to Hack Apple Mac Encryption Password in Just 30 Seconds

How to Hack Apple Mac Encryption Password in Just 30 Seconds

Dec 16, 2016
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
Dropbox Hacked — More Than 68 Million Account Details Leaked Online

Dropbox Hacked — More Than 68 Million Account Details Leaked Online

Aug 31, 2016
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

Researcher releases Free Ransomware Detection Tool for Mac OS X Users

Apr 20, 2016
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
