🔹 𝐌𝐈𝐓𝐌 (𝐌𝐚𝐧-𝐢𝐧-𝐭𝐡𝐞-𝐌𝐢𝐝𝐝𝐥𝐞) 𝐀𝐭𝐭𝐚𝐜𝐤: Interception of communication between two parties by a third party, potentially altering messages (e.g., an attacker intercepts messages between Alice and Bob).

🔹𝐑𝐨𝐨𝐭𝐤𝐢𝐭𝐬: Malicious software that provides privileged access to a computer while hiding the attacker's presence (e.g., an attacker installs a rootkit on a server to avoid detection).

🔹 𝐁𝐨𝐭𝐧𝐞𝐭𝐬: Networks of compromised devices controlled by a central entity, used for malicious activities like DDoS attacks (e.g., thousands of infected computers flood a website).

🔹𝐈𝐏 𝐒𝐩𝐨𝐨𝐟𝐢𝐧𝐠: Sending packets with a fake source IP address to impersonate another device or mask traffic origin (e.g., an attacker tricks a server into thinking a request is from a trusted source).

🔹 𝐃𝐃𝐨𝐒 (𝐃𝐢𝐬𝐭𝐫𝐢𝐛𝐮𝐭𝐞𝐝 𝐃𝐞𝐧𝐢𝐚𝐥 𝐨𝐟 𝐒𝐞𝐫𝐯𝐢𝐜𝐞): Overwhelming a server with traffic from multiple sources, making it unavailable to legitimate users (e.g., using a botnet to crash a website).

🔹𝐃𝐍𝐒 𝐒𝐩𝐨𝐨𝐟𝐢𝐧𝐠: Providing false DNS responses to redirect victims to malicious sites, often to steal information (e.g., redirecting users to a fake bank website).

🦑You've probably heard of JWT - Json Web Tokens.
It is a format designed to securely transfer information between two parties, so it is mainly used to authenticate and transmit information in an encrypted way by using different algorithms when it consists of three parts (Header, Payload, and Signature).

I recently visited a website that manages couriers since I myself am waiting for delivery. He is vulnerable, he is not secure, he is "weak." A weakness that I was able to locate was expressed in the fact that the server stores information about couriers (scheduling) for that courier in JWT format. The information inside is by "x" (identifier) and "y" (shipping). There is no defense mechanism in place, which leads to security weakness and damage to credibility.

It turns out (unfortunately) that anyone can edit the payload content (change a shipping ID to data belonging to another user), and without verifying the signature, the server will receive the edited token as valid, which leads to data tampering, exposing details, and also Rxss because it turns out that there is no filtering on user input.

What's more, it's not normal!
The problem with the JWT header is that it contains information such as id and num, for example, while it does not store information about the encryption type (alg) and the type of token (typ) at all. Using a header to store such data is a security weakness because the header is both unsigned and can be easily modified.

Platforms like Portswigger have modules that focus on attacks on jwt that can also be used to learn about secure development
JWT (Algorithm confusion, Header Injections, etc.)

🦑Protect Your Inbox Like a Pro! 🔒

Your email is a goldmine for cybercriminals, containing personal, professional, and financial information. But fear not—here’s how to safeguard it effectively:

🛡️ Top Email Security Tips:

1️⃣ Enable Multi-Factor Authentication (MFA): A strong password isn’t enough. MFA adds an extra layer of security.
2️⃣ Beware of Phishing Emails: Don’t click on suspicious links or attachments. Verify the sender before taking action.
3️⃣ Use Strong Passwords: Avoid predictable passwords like “password123.” Use a combination of upper/lowercase letters, numbers, and symbols.
4️⃣ Encrypt Your Emails: Protect sensitive information by using email encryption tools.
5️⃣ Keep Software Updated: Ensure your email client and antivirus software are always up-to-date.
6️⃣ Educate Yourself and Your Team: Awareness is your first line of defense. Share best practices with colleagues.

🚨 Common Email Security Threats:

🔸 Phishing: Fake emails designed to steal your information.
🔸 Spoofing: Attackers pretending to be trusted contacts.
🔸 Ransomware: Malicious attachments locking you out of your data.
🔸 BEC (Business Email Compromise): Fraudulent emails targeting businesses.

🔐 Remember: A secure inbox equals a secure life. Take action now to protect your data and privacy!

🦑Detection of teams convoC2 Mainly used by Red Teamers recent days.

Basically it causes out bound requests to C2 Server, exfiltrates command outputs from Adaptive Cards images URLs and inserting data into hidden span tags in Microsoft teams conservations.
The fact that the victim only sends http queries to Microsoft servers and the antivirus doesn't examine MS teams log files and in absence of direct connection between the victim and attacker in this case its very difficult to detect.

Here is the custom KQL to Detect.

CloudAppEvents
| where Timestamp > ago(1h)
| where Application contains "Microsoft Teams"
| where ActionType contains "AppInstalled"
| where parse_json(RawEventData)["AddOnName"] == 'Workflows'

The Proofpoint blog outlines a social engineering tactic where threat actors deceive users into copying and pasting malicious PowerShell scripts, causing malware infections. Groups like TA571 use fake error messages to prompt script execution, delivering malware such as DarkGate and NetSupport. Despite needing significant user interaction, the attack's success hinges on sophisticated social engineering. I have developed a custom detection PowerShell Self-Pwn KQL to identify such scenarios and assist SecOps in isolating affected devices.

🦑How Was the TOR Attacker Caught? 🕵️♂️

🌐 The Dark Web often seems like an untraceable haven for anonymity. But even in the world of TOR (The Onion Router), attackers can be caught! Here’s how:

1️⃣ Human Error: Attackers often make small mistakes, like logging in from a non-TOR connection or revealing identifying details in their communications. Even a single misstep can be critical.

2️⃣ Traffic Analysis: TOR masks your identity by routing traffic through multiple nodes. However, law enforcement can use advanced traffic correlation techniques to identify entry and exit points, especially when they control some TOR nodes.

3️⃣ Compromised Nodes: Investigators may run malicious TOR nodes to intercept traffic. They analyze the data flowing through them, narrowing down potential suspects.

4️⃣ Exploits: Vulnerabilities in TOR or the user’s device/browser can be exploited to reveal real IP addresses. For example, Operation Onymous used malware to expose hidden server locations.

5️⃣ Metadata Tracking: Even encrypted communications leave traces. Authorities piece together patterns, times, and behaviors to zero in on suspects.

💡 Key Takeaway: No system is 100% secure. Cybercriminals often underestimate the combination of technical expertise and human ingenuity behind modern investigations.
