📢 Important Update for WhatsApp, Telegram, Signal & Snapchat Users in India!

India’s Department of Telecommunications (DoT) has given major messaging apps 90 days to implement a new rule called SIM Binding. 🔒 What is SIM Binding? After this rule is enforced, if you 👉 remove the SIM card that was used during account registration, the app will stop working. This means the same SIM used for registration must remain active in the device. 📅 Deadline: February 2026 All messaging platforms in India will be required to follow this policy.

⚠️ This update aims to improve security and prevent misuse of messaging apps. #NEWS @HACKTSUKI

🛡️ Vulnerability in Zora ERC20Z via Uniswap v3/v4 A researcher discovered a critical price vulnerability in the Zora contract, exploiting a Uniswap feature — the ability to manipulate the token price when there is no liquidity by performing swaps with zero amount. The first exploit attempt failed due to protections, but an updated method successfully changed the token price and drained ETH from the pool. Zora quickly fixed the bug and rewarded the researcher with an $11,000 USDC bounty. 🔗 Details

✎ Common Rate Limit Bypass Techniques IP Spoofing Altering a request’s source IP to appear from another device, and rotating IPs lets an attacker bypass per-IP limits. You can use the following Burp Extensions for IP Spoofing: • BurpFakeIP: GitHub • IP-Rotate: GitHub Changing User-Agent Rate-limit systems often track the User-Agent header; changing or randomizing it makes requests appear from different clients, and attackers may brute-force the User-Agent field (e.g., with tools like Burp Suite Intruder). Header Manipulation Header manipulation alters HTTP headers (e.g., X-Forwarded-For, X-Real-IP) to trick servers — bypassing IP restrictions, evading rate limits, or hiding the real IP from logs and filters. • Common Headers by 🕷Spix0r Requesting with Different HTTP Methods Some rate-limiters monitor only certain HTTP methods (e.g., GET/POST); attackers may bypass them by sending requests with other methods (PUT, DELETE, OPTIONS) and testing alternatives (e.g., with Burp Suite Repeater). • HTTP request methods Parameter Name Variation Some backends accept alternate parameter names and still process requests, enabling attackers to bypass input filters, WAFs, or login restrictions.

username=admin&password=1234
user=admin&pass=1234
uname=admin&pwd=1234
login=admin&passwd=1234
u=admin&p=1234
email=admin&key=1234
id=admin&token=1234

Encoding Tricks Encoding represents characters in different formats; attackers use encoding to obfuscate payloads and bypass input filters, WAFs, or validation rules.

user=admin%20        # space after admin
user=admin%00        # null byte injection
user=%61%64%6d%69%6e # 'admin' in hex
user=ad%6Din  # only 'm' is encoded
user=%2561%2564%256d%2569%256e  # double-encoded 'admin'

Case Sensitivity and Font Tricks Case or character-variant changes in strings (emails, usernames, paths) can let attackers bypass security checks or exploit improper validation.

Email: Test@Example.com  # Mixed case
Email: test@example.com   # Lowercase
Email: TEST@example.com   # Uppercase

Using Look-Alike Characters

Email: t3st@3xample.com   # '3' instead of 'e'
Email: t@est@example.com   # Replacing 'l' with 'I' or vice versa

Blank Characters Inserting spaces, null bytes, or invisible characters (e.g., TAB, CRLF) can bypass filters, break input validation, or exploit server input handling.

email=" test@example.com "  # Adding spaces at the beginning and end
email=test@example.com%20  # Adding a space encoded as %20
email=test@example.com%E2%80%8B  # Injecting a zero-width space
email=test@example.com%09  # Tab character
email=test@example.com%0A  # Newline character

*MS Teams Guest Access Can Remove Defender Protection When Users Join External Tenants* Security researchers just uncovered a serious oversight in Microsoft Teams that lets attackers bypass Microsoft Defender protections simply by using guest access. Here’s the catch - 🥸 When you join another company’s Teams space as a guest, you lose your own organization’s protections. Everything phishing safeguards, malware scanning, Safe Links, Safe Attachments all depends on their security setup, not yours. If their security is weak, you're weak. And attackers have figured out how to weaponize that. Why this matters Microsoft recently rolled out a new Teams feature letting users chat with anyone via email including people outside Teams. It’s turned on by default. That means attackers can now: * Create a cheap Microsoft 365 tenant with no Defender protections * Send Teams guest invitations straight to your inbox (the emails look fully legit because they come from Microsoft’s own servers) or even interview invites * Get you to join their tenant * Deliver phishing links or malware inside a “protection-free zone” where your company’s tools can't see anything * Because the invite comes from Microsoft infrastructure, it bypasses SPF, DKIM, and DMARC, so most email filters won’t flag it. Once you accept, your organization has zero visibility into what happens next. As Ontinue’s researchers put it: Your employer’s defenses “never trigger because the attack occurred outside their security boundary.” Why it works ⦁ Guest access = you follow the host tenant’s rules ⦁ A malicious host = no rules ⦁ Defender for Office 365 does not protect you once you cross into their environment ⦁ A low-cost Teams license is all an attacker needs to set up a trap ⦁ This is a textbook example of attackers abusing the “trust” in cloud collaboration. How organizations can protect themselves and experts recommendation to companies: ⦁ Restrict who can accept guest invites (only approved domains) ⦁ Tighten cross tenant access policies ⦁ Disable external Teams messaging if not needed ⦁ Train users to question unexpected chat invites (especially from unknown organizations) Because right now, a Teams invite could be the new phishing email.
