Approved Human Sacrifices: The Deadly Fireworks Tradition

The recent tragic New Year's fireworks-related deaths and injuries in Hawaii and beyond are heartbreaking reminders of an obtuse subcultural tacit approval of human sacrifice via fireworks.

Human sacrifice resulting in death was purposefully practiced by ancient cultures including the Aztecs, Mayans, Chinese, and others; often as part of religious rituals or to appease deities.

In modern US subculture, the sacrifices come in the form of holiday fireworks accompanied by predictable but accidental mayhem and death.

The contemporary Russian-Roulette version of human sacrifice by fireworks often involves alcohol-infused handlers launching illegal aerial incendiaries that can explode in horrific ways.

It would, of course, be preferable to leave the missile-launching to the professionals but alas; every holiday-drunken rocket-man is another "hold-my-beer" expert in the field of bomb-handling. Then, and all too frequently, Darwinism prevails as they thin the herd of those unfit for continued survival with complete appendages.

The tragic and unacceptable collateral damages are those innocent and unwitting victims who were simply on the periphery of the disasters.

In 2023

According to the U.S. Consumer Product Safety Commission's (CPSC) 2023 Report, fireworks-related deaths and injuries were reported as follows:

Deaths

• In 2023, there were 8 reported non-occupational fireworks-related deaths. The circumstances of these deaths included the following:
• 5 deaths associated with fireworks misuse
• 2 deaths associated with device malfunction
• 1 death involved unknown circumstances

Note: Those 2023 numbers are considered minimums, as reporting may be incomplete.

Injuries

The CPSC estimated approximately 9,700 fireworks-related injuries treated in U.S. hospital emergency departments in 2023. This translates to an estimated rate of 2.9 emergency department-treated injuries per 100,000 individuals in the United States, which is a slight decrease from 3.1 estimated injuries per 100,000 individuals in 2022.

Injury Trends

Despite recent declines since 2020, there has been an overall increasing trend in fireworks-related injuries from 2008 to 2023, with an average increase of 561 injuries per year.

Types of Injuries

• Hands and fingers were the most commonly injured body parts (35% of injuries)
• Head, face, and ears accounted for 22% of injuries
• Eyes accounted for 19% of injuries
• Burns made up about 42% of the emergency department-treated fireworks-related injuries

In 2024 (accounting incomplete)

Based on the available information, there were several deaths reported from 2024, with the most significant incident occurring in Hawaii on New Year's Eve.

The tragic explosion in a Honolulu neighborhood on New Year's Eve 2024 resulted in at least five fatalities and critically injured 20 others. One three year old child victim died a few days later from burns. It was one of the most severe fireworks-related accidents reported in 2024. Another fireworks death also occurred elsewhere on the island bringing the Honolulu County death toll thus far to five.

Hundreds of thousands of permits are issued for authorized and legal non-aerial fireworks in Honolulu County every year. But offenders can also obtain unlawful smuggled fireworks, or disassemble and remove the powder from smaller firecrackers and reassemble the contents into much larger explosives.

Other Reported Fatalities

While full data for the entire year of 2024 is not available, there were other fireworks-related deaths reported across the United States during Fourth-of-July celebrations included the following:

• A 34-year-old man died after handling fireworks on Chicago's Northwest Side
• A 25-year-old man died in a fireworks mishap in LaSalle, Illinois
• In South Carolina, a 41-year-old man died after igniting a large firework device and placing it on his head
• In Alabama, a 20-year-old man from Harvest suffered fatal injuries in a fireworks accident in Madison County

Government Response

In the wake of the latest tragedies, authorities are predictably calling for increased penalties for offenders along with more enforcement activity and improved public awareness.

Drone Entertainment Alternatives?

The trend towards flying lighted drone displays for celebrations and holidays is rapidly gaining popularity as a captivating alternative to traditional fireworks. This emerging form of entertainment combines cutting-edge technology with creative artistry to produce mesmerizing aerial spectacles.

Conclusion

In some ways, our culture has evolved from human sacrifice, in other ways....not so much.

It is unlikely that increases in penalties, more law enforcement and improved prevention activities will have much effect on the explosive-obsessed sub-culture. We can anticipate the next wave of sad human sacrifices at the next bomb-fest holiday.

Perhaps someday our species will evolve and replace destructive fireworks with something less lethal; until then, take cover.

• Allows access to decrypted data in memory
• May capture encryption keys or passphrases

Tools:

• AccessData's FTK Imager
• EnCase Enterprise
• ProDiscover IR
• X-Ways Capture

Finding Unencrypted Copies

Investigators often search for unencrypted copies of data that may exist elsewhere on the system or remotely in cloud storage[3]:

• Temporary files created during the encryption process
• Copies stored in the paging file (pagefile.sys)
• Unencrypted backups or copies in other locations

Obtaining Encryption Passphrases

Acquiring the encryption passphrase can provide full access to the encrypted data[3]. Methods include:

• Searching the area around the computer for written passphrases
• Interviewing the suspect
• Monitoring the suspect's computer use
• Trying passwords used for other accounts (e.g., email, personal devices)

Specialized Decryption Tools

Forensic examiners may employ specialized software designed to decrypt specific types of encryption[5][6]:

• EnCase
• Forensic Toolkit (FTK)
• Elcomsoft Forensic Disk Decryptor
• Passware Kit Forensic

These tools may recover deleted files, decrypt encrypted data, and analyze corrupted information.

Brute-Force Attacks

When other methods fail, investigators may attempt brute-force attacks to guess the encryption key[6]. This can be time-consuming but may be successful if the encryption is not particularly strong.

Exploiting Vulnerabilities

In some cases, forensic examiners may leverage known vulnerabilities in encryption implementations[1]. For example, older versions of Windows had weakly protected EFS private keys that could be exploited.

Legal and Cooperative Approaches

Sometimes, legal process can be used to gain access to encrypted data[3]:

• Obtaining court orders for suspects to provide decryption keys
• Negotiating plea bargains in exchange for decryption cooperation
• Leveraging data protection laws to request cooperation from service providers

Focusing on Metadata and Unencrypted Data

When full decryption is not possible, examiners may focus on[3]:

• Analyzing metadata associated with encrypted files
• Examining unencrypted portions of the system
• Investigating network traffic and communication patterns

By employing these methods, digital forensics examiners may overcome the challenges posed by encryption and recover evidence. However, it's important to note that as encryption technologies advance, forensic techniques must continually evolve to keep pace.

Be Cautious When Using Quick Response (QR) Codes

QR codes are almost ubiquitous, offering convenience and quick access to information. However, their use has attracted the attention of cybercriminals who exploit the pixelated squares for malicious purposes. Let's explore the dangers and security risks associated with QR codes, as well as how to identify and protect yourself from malicious QR codes.

Dangers and Security Risks of QR Codes

Malicious URL Redirection

One of the primary risks of QR codes is their ability to redirect users to harmful websites[1]. When scanned, a malicious QR code can lead to:

• Phishing sites designed to steal credentials or personal information

• Websites that automatically download malware onto devices

• Fake payment portals that capture financial data

QR Code Tampering

Cybercriminals can easily manipulate QR codes to carry out various attacks[1]:

• Replacing legitimate QR codes with malicious ones in public spaces

• Creating counterfeit QR codes that mimic authentic ones

• Embedding malicious data that exploits vulnerabilities in QR readers or operating systems

Data Theft and Privacy Concerns

Scanning a malicious QR code can lead to unauthorized access to personal information[2]:

• Installation of spyware or malware that exfiltrates data from mobile devices

• Exploitation of device vulnerabilities to gain access to sensitive information

• Collection of personally identifiable information (PII) through fake forms or websites

Network-based Attacks

QR codes can also be used to compromise network security:

• Configuring devices to connect to compromised Wi-Fi networks

• Executing SQL injection attacks to manipulate databases

• Initiating drive-by downloads of malicious software

How to Identify a Malicious QR Code

To protect yourself from QR code-based threats, follow these steps [3][5][8]:

1. Check the source: Verify that the QR code comes from a reputable and trustworthy source. Be especially cautious of codes found in public spaces or received from unknown senders.

2. Examine the design and branding: Legitimate QR codes often feature customized designs and branding consistent with the company they represent. Generic or poorly designed codes may be suspicious.

3. Look for signs of tampering: If the QR code is in a physical location, check for any evidence of manipulation, such as a sticker placed over the original code.

4. Preview the URL: Use a QR code scanner that allows you to preview the destination URL without actually visiting the site. Ensure the URL uses HTTPS and matches the expected destination.

5. Be wary of shortened URLs: Suspicious QR codes may use URL shorteners to hide malicious links.

6. Use secure scanning practices: Opt for your device's built-in camera app or a reputable QR code scanner instead of third-party apps that may request unnecessary permissions[4].

7. Keep your device updated: Ensure your smartphone's operating system and security software are up-to-date to protect against potential vulnerabilities[5].

8. Be cautious of immediate actions: Avoid scanning codes that prompt you to download unfamiliar apps or enter sensitive information immediately.

9. Check for secure URLs: Legitimate websites should use HTTPS in their web address, not HTTP. Look for a padlock symbol near the URL[8].

Mitigation Strategies

To protect yourself from QR code-based threats:

1. Verify the source and legitimacy of QR codes before scanning

2. Use built-in smartphone camera apps instead of third-party QR code scanners

3. Check the URL preview before accessing the linked content

4. Keep your device's operating system and security software up to date

5. Be cautious when scanning QR codes in public places or from unknown sources

6. Use antivirus software on your devices[3]

7. Be aware of scams and offers that seem too good to be true[3]

8. Manually enter URLs when in doubt[5]

9. Use QR code scanners with security features that check URLs for known threats[4]

Conclusion

While QR codes offer convenience, they also present security risks. By understanding these dangers and implementing proper precautions, users can continue to benefit from QR technology while minimizing their exposure to potential threats. Always remain vigilant and prioritize your digital security when interacting with QR codes.
