Rising Cybercrime Threats and Prevention Measures Ahead of 2024

 

According to projections from Statista, the FBI, and the IMF, the global cost of cybercrime is anticipated to experience a substantial increase. By 2027, it is estimated to surge to $23.84 trillion, marking a significant rise from the $8.44 trillion reported in 2022. 

Security expert James Milin-Ashmore, from Independent Advisor VPN, has provided a comprehensive list of 10 crucial guidelines aimed at enhancing digital safety by avoiding sharing sensitive information online. 

These guidelines serve as proactive measures to combat the rising threat of cybercrime and safeguard personal and confidential data from potential exploitation. 

1. Avoid Sharing Your Phone Number on Random Sites 

Sharing your phone number online can expose you to a range of security risks, warns an expert. Cybercriminals could exploit this information to gather personal details, increasing the likelihood of identity theft and other malicious scams: 

  • Subscriber Fraud: Scammers set up fake cell phone accounts with stolen info. 
  • Smishing: Fraudsters send text messages to trick victims into revealing data or visiting harmful sites.
  • Fake Call Frauds: Scammers pose as legitimate entities to extract sensitive information. 
  • Identity Theft: Phone numbers are exploited to commit financial fraud and impersonate individuals. 

2. Do Not Update Your Current Location 

It is not new or unknown that people share their current locations on social media handles however, experts caution against sharing personal addresses or current locations online, citing heightened risks of theft, stalking, and malicious online activity. 

Such information can be exploited to tailor phishing attempts, rendering them more convincing and increasing the likelihood of falling victim to scams. 

3. Do Not Post Your Holiday Plans 

As the holiday season approaches, many individuals may feel inclined to share their vacation plans on social media platforms. However, security experts are warning against this seemingly innocent practice, pointing out the potential risks associated with broadcasting one's absence from home. 

Announcing your vacation on social media not only informs friends and family of your whereabouts but also alerts criminals that your residence will be unoccupied. This information could make your home a target for burglary or other criminal activities. 

4. Do Not Take Risks of Sharing Password Online 

Passwords serve as the primary defense mechanism for safeguarding online accounts, making them crucial components of digital security. However, security expert emphasizes the importance of protecting passwords and refraining from sharing them online under any circumstances. Sharing passwords, regardless of the requester's identity, poses a significant risk to online security. 

Unauthorized access to sensitive accounts can lead to various forms of cybercrime, including identity theft, financial fraud, and data breaches. 

 5. Protect Your Financial and Employment Information 

Experts caution against sharing sensitive financial or employment details online, highlighting the potential risks associated with divulging such information. Financial details, including credit card numbers and bank account details, are highly sought after by online fraudsters. Similarly, sharing employment information can inadvertently provide criminals with valuable data for social engineering scams. 

 6. Protect Your ID Documentation 

Expert urges individuals to refrain from posting images of essential identification documents such as passports, birth certificates, or driver's licenses online. These documents contain sensitive information that could be exploited by identity thieves for various criminal activities, including opening unauthorized bank accounts or applying for credit cards. 

7. Stop Sharing Names of Your Loved Ones/Family/Pets 

Security experts advise against sharing personal details such as the names of loved ones or pets online. Hackers frequently attempt to exploit these details when guessing passwords or answering security questions. 

 8. Protect Your Medical Privacy 

Your medical history is a confidential matter and should be treated as such, caution experts. Sharing details about the hospitals or medical facilities you visit can inadvertently lead to a data breach, exposing personal information such as your name and address. 

 9. Protect Your Child's Privacy 

Expert warns against sharing information about your child's school online, as it can potentially put them at risk from online predators and expose them to identity theft. 

 10. Protect Your Ticket Information 

Expert advises against sharing pictures or details of tickets for concerts, events, or travel online. Scammers can exploit this information to impersonate legitimate representatives and deceive you into disclosing additional personal data. 

Furthermore, in 2023, the Internet Crime Complaint Center (IC3) reported a staggering surge in complaints from the American public. A total of 880,418 complaints were filed, marking a significant uptick of nearly 10% compared to the previous year. 

These complaints reflected potential losses exceeding $12.5 billion, representing a substantial increase of 22% in losses suffered compared to 2022. Also, according to the Forbes Advisors, Ransomware, Misconfigurations and Unpatched Systems, Credential Stuffing, and Social Engineering will be the most common threats in 2024.

Zeppelin2 Ransomware: An Emerging Menace in the Dark Web Ecosystem

 

In a recent update from an underground online forum, a user is actively promoting the sale of Zeppelin2 ransomware, providing both its source code and a cracked version of its builder tool. This malicious software, known for its destructive capabilities, has garnered the attention of cybersecurity experts and law enforcement agencies globally.

The forum post asserts that the user successfully breached the security measures of the Zeppelin2 builder tool, originally designed for data encryption. The post includes screenshots of the source code, shedding light on the intricate details of the build process and revealing that the ransomware is programmed in Delphi.

The Zeppelin2 ransomware builder tool, being promoted by the threat actor, showcases various features, such as file settings, ransom notes, IP logging, startup commands, task killers, and auto-unlocking busy files. The threat actor underscores the ransomware's capability to comprehensively encrypt files, rendering data recovery impossible without a unique private key held by the attackers.

Upon completing the encryption process, victims are presented with a ransom note declaring the encryption of all their files. The note instructs victims to contact the attackers via email and offers a method for testing the legitimacy of the decryptor by sending a non-valuable file.

Reports indicate that Zeppelin2 ransomware demands ransom payments in Bitcoin, with extortion amounts ranging from several thousand dollars to over a million dollars. The Federal Bureau of Investigation (FBI) and the Cybersecurity and Infrastructure Security Agency (CISA) have jointly issued a cybersecurity advisory to address the Zeppelin2 threat.

Zeppelin2, employed by threat actors since 2019 and continuing at least until June 2022, targets various sectors through its ransomware-as-a-service (RaaS) model. These sectors include defense contractors, educational institutions, manufacturers, technology companies, and notably, organizations in the healthcare and medical industries.

The ransomware's modus operandi involves exploiting vulnerabilities such as remote desktop protocol (RDP) exploitation, SonicWall firewall vulnerabilities, and phishing campaigns to gain access to victim networks. Before deploying the Zeppelin2 ransomware, threat actors meticulously map and enumerate the victim's network, identifying critical data enclaves, including cloud storage and network backups.

Consistent with ransomware groups, Zeppelin2 operators exfiltrate sensitive corporate data with the intention of making it accessible to buyers or the public if the victim resists complying with their demands.

Of significance, the FBI has observed instances where Zeppelin2 actors execute their malware multiple times within a victim's network, generating different IDs or file extensions for each attack instance, necessitating multiple unique decryption keys.
