Create Compressed, Encrypted Archives with tar + gpg on Linux
avatar

Need to back up or share sensitive files on Linux? A simple, time-tested pattern is:

  1. archive with tar,
  2. compress (e.g., gzip), and
  3. encrypt with GnuPG (gpg).

Below are the most useful one-liners for both password-based (symmetric) and public-key (asymmetric) workflows, plus how to decrypt and list contents without creating intermediates.

Symmetric encryption (password)

Use a passphrase you’ll remember (or store it in a password manager). This creates a compressed (.tar.gz) archive and pipes it straight into gpg for encryption:

# Create: directory -> tar.gz -> gpg (prompted for passphrase)
tar -cvzf - /path/to/dir | gpg --symmetric --output secret.tar.gz.gpg

# Decrypt + extract back to current directory
gpg --decrypt secret.tar.gz.gpg | tar -xvzf -

This pattern avoids temporary plaintext files by streaming via STDIN/STDOUT.

Asymmetric encryption (public key)

If you’re sending data to someone else, encrypt to their public key so only they (with the private key) can decrypt:

# Encrypt to a recipient (use their email, key ID, or fingerprint)
tar -cvzf - /path/to/dir | gpg --encrypt --recipient [email protected] --output share.tar.gz.gpg

# Recipient decrypts and extracts
gpg --decrypt share.tar.gz.gpg | tar -xvzf -

If you don’t yet have keys: generate/import keys first, then use --recipient.

Listing contents without extracting

You can peek inside an encrypted archive:

gpg --decrypt secret.tar.gz.gpg | tar -tzf -

This decrypts to STDOUT and lists the tarball’s table of contents (-tzf) without writing files.

Notes & tips

  • Compression choices: swap -z (gzip) for -j (bzip2) or -J (xz) to trade speed vs. ratio.
  • File extensions: pick something descriptive, e.g. .tar.gz.gpg.
  • No intermediates: the pipe (|) keeps plaintext off disk during creation and decryption.
  • Alternative tool: gpgtar bundles archiving and GPG in one command if you prefer fewer moving parts.

Common pitfalls

  • Wrong recipient or missing key: ensure you imported/selected the correct public key before --encrypt.
  • Passphrase prompts in scripts: for unattended scripts, look into gpg --batch and pinentry options—handle secrets carefully.

# Beware of the Malware: CISA’s Latest Warning

Hello, dear readers! 🌟 Have you heard the latest buzz from the **Cybersecurity and Infrastructure Security Agency** (CISA)? They recently issued a cautionary tale about two malware types exploiting vulnerabilities in **Ivanti EPMM**. Now, before you scratch your head and ask, “What in the blue blazes is that?”, let’s break it down.

**Spoiling for a Malware Showdown**
A dive into the depths of cyber safety reveals that the vulnerabilities in question are **CVE-2025-4427** and **CVE-2025-4428**. Don’t just roll your eyes at the technical jargon — these vulnerabilities turned into a veritable buffet for cyber criminals, empowering them to execute arbitrary code on compromised servers. Essentially, that means they could play puppet master in a network, pulling strings and performing unauthorized tasks. Yikes!

## What to be Concerned About

News of these malware strains should set off alarm bells for several reasons:

1. **Authentication Bypass**: CVE-2025-4427 allows attackers access to protected resources without breaking a sweat. Think of it as leaving the front door wide open while you’re out shopping.

2. **Remote Code Execution**: CVE-2025-4428 is like a welcome mat for attackers. It enables them to run their code on the target server without ever asking for permission. Unsurprisingly, this is the dream scenario for any malicious actor.

3. **Persistent Threats**: CISA highlighted that the attackers can drop two sets of files that not only install themselves but also ensure that they stick around like an unwelcome houseguest. The malware can set itself up to continuously inject and execute arbitrary code, maintaining a foothold in the system.

**Moral of the Story?** Stay alert! This issue presents a serious threat to systems that haven’t been updated to the latest, secure versions. CISA recommends immediate action to patch your systems and monitor for suspicious activities. After all, you don’t want to be the one left holding the bag when these cyber ne’er-do-wells come knocking.

tags: security, WatchGuard, Firebox, vulnerability

**WatchGuard has issued a significant warning, and you should listen up!** The cybersecurity landscape is as unpredictable as a cat in a room full of laser pointers, and the latest scoop has come directly from the folks at WatchGuard regarding a critical vulnerability in their handy-dandy Firebox firewalls. If your organization relies on Firebox devices, this is not a drill! You can read the full article by the ever-knowledgeable [Sergiu Gatlan](https://www.bleepingcomputer.com/news/security/watchguard-warns-of-critical-vulnerability-in-firebox-firewalls/) to get the nitty-gritty.

### What’s the fuss all about?

WatchGuard’s latest update warns about a remote code execution vulnerability, tracked as CVE-2025-9242. This is no small potatoes; it’s an out-of-bounds write flaw allowing attackers to execute random code remotely. Imagine someone getting into your house without a key—yikes! And as if that weren’t enough, if your Firebox is configured to use IKEv2 VPN, you might be at even greater risk.

It’s like throwing caution to the wind while trying to catch butterflies—trust me, it typically doesn’t end well.

### Key Concerns to Consider

1. **Remote Code Execution (RCE):** This is not a fancy term for home automation; it means someone could potentially control your firewall from miles away! This threat seeks to exploit weaknesses, and if your firewall is left unattended, it’s like leaving your door wide open.

2. **Multiple Firmware Versions Affected:** The vulnerability impacts Fireboxes running Fireware OS versions 11.x and 12.x, among others. So, if you’re operating on outdated firmware, it’s time to upgrade! Nobody likes a stubborn technology that refuses to evolve.

3. **Maintenance Status:** Even if you’ve deleted vulnerable configurations, you may still be in hot water if a branch office VPN is configured to a static gateway peer—not an ideal position, folks.

4. **Attractive Target:** Ransomware gangs, like the Akira crew, are licking their chops over such exploitable vulnerabilities. You wouldn’t invite guests over for dinner only to serve them a platter of vulnerabilities.

### What You Can Do

– **Get Patching:** If you haven’t patched the latest updates yet, consider this friendly advice: stop procrastinating! The basic moves here involve upgrading to versions 12.3.1_Update3 (B722811), 12.5.13, 12.11.4, or 2025.1.1.

– **Temporary Workarounds:** For those with branch office VPN configured, WatchGuard offers a temporary workaround. Disable dynamic peer BOVPNs, implement new firewall policies, and disable default policies managing VPN traffic. More details are in their [support document](https://techsearch.watchguard.com/KB?type=Article&SFDCID=kA1Vr000000DMXNKA4&lang=en_US).

– **Stay Alert:** Yes, it’s all fun and games until someone gets hurt. While there’s no current exploitation of this vulnerability in the wild, you don’t want to be the first headline rolling out the door, right?

Think of it like maintaining your car. Accidents happen when you ignore the “Check Engine” light. So, let’s not wait for the inevitable mess with the FBI knocking on your door because of these vulnerabilities!

For the more adventurous among us, you can follow along in greater depth by checking out the original article [here](https://www.bleepingcomputer.com/news/security/watchguard-warns-of-critical-vulnerability-in-firebox-firewalls/) and arm yourself with knowledge.

Stay safe out there; remember, **Security is a streak you can’t afford to break.**

# Beware of the Groundbreaking New Ransomware: HybridPetya

Ahoy, cyberspace voyagers! 🚀 It appears we’re in for a rocky ride as a new beast has reared its ugly head in the land of malware: HybridPetya! With a splash of *Petya* and a dab of *NotPetya* charm, this ransomware is not just about stealing your Bitcoin (though it does that too) – it’s about the kind of audacity that can even make UEFI Secure Boot squirm.

## What is HybridPetya?

HybridPetya employs a sneaky technique that allows it to **bypass UEFI Secure Boot**—talk about slashing security! It takes a well-known vulnerability, **CVE-2024-7344**, and dances its way past what’s supposed to be a sturdy iron gate. Reminiscent of its forebears, HybridPetya encrypts the NTFS Master File Table (MFT) and leaves a ransom demand of $1,000 in Bitcoin. But wait, there’s more! This malware doesn’t just hope to steal your coins—it makes your system sing its errors under the guise of a *CHKDSK* repair process while it’s stealthily encrypting your files!

🚨 **[Read the full article here](https://thehackernews.com/2025/09/new-hybridpetya-ransomware-bypasses.html)** 🚨

## Why Should You Be Concerned?

Now, while our first instinct might be to cackle nervously at the genius of the attackers, let’s pause for a moment. There are some alarm bells ringing that we can’t ignore:

1. **Persistence Across Systems**: This isn’t just a one-and-done ransomware; it bypasses UEFI, meaning even the most modern, well-protected systems can fall victim. If it’s making waves in 2025, just imagine how it might evolve!

2. **Subtle Manipulation**: The genius of Trickery! Users might think their computer is merely ‘repairing’ itself before they realize data is being *devoured* by ransomware. It’s an ingenious deception that plays on user expectations.

3. **Tied to Existing Vulnerabilities**: This highlights a significant **security gap** within firmware (UEFI). If hackers are exploiting such vulnerabilities, what else could they be up to? It raises a huge question mark over the security of not just our systems, but how we manage and configure them.

4. **Social Engineering**: Based on the ransom’s setup, the malware preys on your panic. Victims may scramble to pay the ransom in hopes of getting their files back, leading to a spiral of anxiety and further risks like secondary fraud or additional infections.

5. **Data Integrity Chances Are Slim**: Once files go on the mend with a malicious program, can we still trust their integrity? Not if the malware has obliterated the MFT!

In this wild game of cyber-tag, we, the players, need to remain vigilant and resourceful!

## What Can You Do?

So, as vigilant cybersecurity warriors, how do we combat such threats? Here are a few handy tips:

– **Keep Systems Updated**: Regular firmware updates can prevent vulnerabilities from being exploited. Don’t be the low-hanging fruit that shady hackers plummet for!

– **Use Robust Security Software**: Equip yourself with security tools that focus on detecting these specific malware strains, not just your run-of-the-mill antivirus.

– **Educate Yourself and Others**: Stay informed about the latest threats and teach those around you. Knowledge is power, after all!

– **Implement Backup Solutions**: Ensure your data is backed up regularly. Having your information secure in different locations can save you from the abyss of despair if ransomware strikes.

– **Stay Calm Under Pressure**: If you ever find yourself in a situation involving ransomware, resist the urge to panic. Take a breath, gather your resources, and approach the situation methodically.


Remember, folks—**Security is a streak you can’t afford to break.** Stay safe out there, and keep those digital shields up! 🛡️
