С развитием квантовых компьютеров возникает вопрос о безопасности существующих криптографических систем, включая блокчейн и криптовалюты. В этой статье мы рассмотрим, как квантовые вычисления могут повлиять на безопасность блокчейна в 2025 году и какие меры предпринимаются для защиты.

1. Квантовая угроза для криптографии:
• Квантовые компьютеры способны решать определенные задачи значительно быстрее классических компьютеров, что ставит под угрозу традиционные криптографические алгоритмы.
• Алгоритмы квантовых вычислений не универсальны и не дают преимущества в задачах, требующих полного перебора вариантов.
2. Влияние на блокчейн и биткойн:
• Быстродействие реально существующих квантовых компьютеров не столь уж и высоко, а алгоритмы квантовых вычислений не универсальны — они не дают преимущества в задачах, требующих полного перебора вариантов.
• Более уязвима схема электронной подписи на основе эллиптической кривой.

3. Меры по обеспечению безопасности:
• Разработка квантово-устойчивых криптографических алгоритмов.
• Переход на альтернативные схемы подписи, не дающие преимуществ квантовым компьютерам при взломе.

Несмотря на потенциальные угрозы со стороны квантовых вычислений, индустрия блокчейна активно работает над усилением безопасности. Инвесторам и пользователям рекомендуется следить за развитием технологий и обновлениями в сфере криптографии.

According to Odaily, a deep analysis by SlowMist has uncovered how a hacker stole $230 million from Cetus by exploiting a math overflow vulnerability in the get_delta_a function. The flaw bypassed a protection mechanism (checked_shlw), letting the attacker manipulate parameters and trick the system into miscalculating token values.
Example :
Imagine a smart contract says:
“You give me 1 haSUI, I give you 1,000,000 USDT.”
Due to an overflow bug in the math calculation, the attacker made it seem like they only needed 1 token to receive millions in liquidity. In reality, they should have needed a huge amount. By carefully choosing the inputs, the attacker got billions in value almost for free.
Takeaway:
This is a powerful reminder that even a tiny math error in a smart contract can lead to massive losses. Overflow vulnerabilities must be taken seriously. Every calculation needs proper limits, validation, and safe coding practices to avoid this kind of disaster.

$CYBER security WhatsApp Hacking: Understanding the Threats and Protecting Yourself

WhatsApp, one of the most widely used messaging apps globally, has been facing numerous hacking threats. Recently, a sophisticated malware campaign was discovered exploiting WhatsApp in Brazil to spread the Eternidade Stealer banking trojan. This campaign uses social engineering and automated messages to steal financial credentials and personal data. ¹

Recent WhatsApp Hacking Incidents

- A vulnerability in WhatsApp exposed phone numbers and profile information of 3.5 billion users, including nearly 750 million Indian users. The researchers who discovered the vulnerability said it was the largest data leak in history.

- A hacking campaign targeted approximately 90 users, including journalists and civil society members, using spyware from an Israeli company called Paragon Solutions.

- WhatsApp patched a security vulnerability that allowed hackers to take advantage of a second vulnerability on Apple devices and hijack the machines, impacting fewer than 200 users worldwide. ² ³ ⁴

How Hackers Take Over WhatsApp Accounts

Hackers can take over WhatsApp accounts through various methods, including ⁵:

- SIM swapping: tricking the victim's mobile operator into transferring their phone number to a new SIM card.

- Phishing: sending fake messages or emails that appear to be from WhatsApp, asking users to disclose their account details or verification codes.

- Malware: infecting the victim's device with malware that can intercept SMS or WhatsApp messages.

Protecting Yourself from WhatsApp Hacking

To protect yourself from WhatsApp hacking, follow these tips:

- Enable two-factor authentication: add an extra layer of security to your WhatsApp account by requiring a six-digit PIN when registering your number on a new device.

- Be cautious with verification codes: never share your verification code with anyone, and be wary of messages or calls asking for your code.

- Keep your device and WhatsApp up-to-date: regularly update your device's operating system and WhatsApp to ensure you have the latest security patches.

- Use a reputable antivirus app: install an antivirus app that can detect and block malware.

By being aware of the threats and taking necessary precautions, you can protect yourself from WhatsApp hacking and keep your personal data safe.

Warning: Critical Security Vulnerability Detected in Smartphones – Take This Essential Step to Prevent Your Cryptocurrencies from Being Stolen.
Apple has released an urgent update for iOS 18.6. This critical vulnerability, affecting Safari and Chrome browsers, allows attackers to inject malicious code onto your device simply by visiting a website. The danger begins without any downloads.
Of particular concern is that the iPhone XS and all later models are at risk. Attackers can exploit this vulnerability to steal passwords, bank details, and initiate covert surveillance operations.
Apple and cybersecurity experts are urging users to update iOS immediately. Another important reminder: Never store your seed phrase and private keys as photos in your phone's gallery. This simple precaution can protect you from numerous security threats.
Meanwhile, Kaspersky researchers have discovered a new family of Trojans targeting iOS and Android devices. This malware activates by installing specific apps and granting access to the photo gallery. This poses a particularly significant risk to cryptocurrency users.
