Coinbase Email Didn’t Arrive – Over the weekend, news broke that a huge $ 16 billion user identity, including past violations and newly stolen login data, began to circulate online. It is not clear who updated the data set and re -published it. Although much of the database is the revival of past infringements, the fact that it has been re -updated is disturbing. The data set is considered to be one of the largest only collections of vulnerable accounts.
Hackers use this data to carry out various attacks and became one of their targets.
Coinbase Email Didn’t Arrive
The phishing attack on my personal assets and accounts was the most sophisticated on June 19th I have ever met during my decades of cyber security. The attackers first created the illusion of attacking my reports on several platforms, then applying for Coinbase and offering to “help”. Classical social engineering tactics have been combined with coordinated tactics of text messages, phone calls and false E -mail, all of which are used to create a false feeling of urgency, credibility and scale. Achieving a false attack and power was key to its deceptive nature.
The History And Success Of Coinbase
Below I detail the attack process, analyze the red flags I noticed during the process and the protective measures I have taken. At the same time, I share key lessons and practical suggestions to keep cryptographic investors safe in the constantly developing threat environment.
Historical and recently leaked data can be used by hackers to carry out highly targeted multi -channel attacks. This again confirms the importance of plywood security protection, clear user communication mechanisms and real -time response strategies. Both institutions and individual users can acquire practical tools from this case, including control protocols, domain name identification habits, and response steps, which can prevent instantaneous negligence from becoming the main security skills.
The attack began around 15:15. Et on Thursday with an anonymous text message claiming that someone has tried to deceive mobile operators to give someone else my phone number, the tactic known as SIM Swaging.
Please note that this message is not from an SMS number, but from a usual 10-digit phone number. Legitimate businesses use short codes to send SMS messages. If you receive a text message from an unknown standard length that is supposed to come from a business, it is probably a fraud or a phishing experiment.

The messages also contained contradictions: the first text message indicated that there was an infringement around the San Francisco Gulf, while a later message occurred in Amsterdam.
Replacing SIM is extremely dangerous when successful, as attackers can obtain one -time verification codes that most companies use to reset passwords or access accounts. However, this was not a real SIM replacement, and the hackers gave the basis for a more sophisticated fraud.
The attack then escalated and allegedly started to get one-time verification codes from Venmo and PayPal via SMS and WhatsApp. This made me think that someone tried to sign in to my accounts on different financial platforms. Unlike suspicious Carrier SMS messages, these verification codes came from short codes that seemed legitimate.
About five minutes after receiving the text message, I received a call from a California number. The caller, who called him “Mason” spoke with a pure American accent and claimed to be from the Coinbase investigative group. He said more than 30 attempts have been made in the last 30 minutes to reset passwords and report on the Coinbase chat window. According to “Mason”, the so-called attacker accepted the first level of security checks for password reset, but failed at the second level of authentication.

He told me that the other party could specify the last four digits of my ID, the full driver’s license number, the home address and the full name, but did not enter the entire identity card number or the last four digits of the Coinbase account. Mason said this contradiction triggered the alarm of the Coinbase security team and made them contact with me to check credibility.
Official exchange programs, such as Coinbase, will never be proactive to call users unless they initiate a service request on the official website. If you would like to know more about customer service regulations please read this Coinbase document.
After informing the “bad news”, Mason suggested to protect my account by blocking further attack channels. He started with API relationships and related wallets, claiming to be withdrawn to reduce the risk. He listed several contacts, including BitSpP, TradingView, Metamask wallets, etc., which I did not recognize some, but I assumed that I may have set up and forgot.
So far, Mason has not requested any personal information, wallet address, two factors check code or one -time passwords that are usually commonly common requests. The total interaction process is very safe and preventive.

Then came the first pressure attempt, creating a sense of urgency and vulnerability. After completing the so -called “security check”, Mason claimed that one of Coinbase’s subscription services had ceased to be accountable because my account was called high risk. This meant that my Coinbase wallet was no longer covered by FDIC insurance, and I would not be able to compensate if the attacker successfully stole the funds.
In retrospect, this argument should have been a striking mistake. Contrary to bank deposits, cryptographic assets are never protected by FDIC insurance, and although Coinbase customer can hold dollars at FDIC banks, the stock exchange itself is not an insured institution.
Mason also warned that the 24 -hour countdown had begun and that expired bills were closed. It would require a complicated and long procedure to resolve. It is even more scary and claimed that if an attacker receives my entire social security number during this period, it could even steal funds from the frozen account.
Later, I consulted with the real Coinbase customer service team and learned that the invoice lock is the security measure they recommend. The unlocking process is actually simple and safe: provide a photo of your ID and self -self, and the replacement justifies your identity and quickly restores access.

Then I got two e -MAILs. The first was a Coinbase byte news subscription confirmation letter, which was only a standard E -Mail launched by the E -Mail address through the official website form. This was obviously an attempt to disturb my judgment with Coinbase’s official e -mail to improve the credibility of fraud.
The second, more confusing email was received at no-reply@info.coinbase.com, stating that Coinbase One Account Protection was removed. This E -Mail, which came from the legitimate province of Coinbase, was extremely misleading – it would have been easy to notice if it came from a suspicious range, but it seemed credible because it seemed to come from an official title.
Mason then suggested that I transfer the assets to several signature wallets, the so -called Coinbase Vault for safety. He even asked Google to be “Coinbase Vault” to check official documentation to prove that this is a legitimate service that Coinbase has been providing for years.
I said I was reluctant to make such a significant change without fully investigating. He understood and encouraged me to thoroughly research and supported him first contact with the carrier to prevent SIM from replacing. He said he would call back in 30 minutes to continue the next step. Immediately after scanning, I received a text message that confirms the call and appointment.
Fort & Forge
After confirming that the carrier was not SIM, I immediately changed the password of all accounts. Mason called back according to the schedule and we started discussing the next steps.
At this point, I proved that Coinbase Vault is really a real service provided by Coinbase. This is a supervisory solution, with increased security through multiple signature permits and 24 hours delayed subtraction, but this is not a real independent cold wallet.
Mason then sent me a link to Vault-coinbase.com, claiming that you can review the security settings discussed in the first call. Once the review has been completed, the devices can be transferred to the vault, and at this moment the professionalism of network security was eventually formed.
After entering the case number he has provided, the open page showed the so-called “API connection removed” and “Create Coinbase” button. I immediately checked the website’s SSL certificate and found that this domain name, which was registered for only one month, had nothing to do with Coinbase. Although SSL certifications can often create false legitimacy, formal corporate certificates have clear ownership, and this discovery immediately stops the operation.

Coinbase made it clear that it would never use unofficial domain names. Even if a third party service is used, there must be a subdomain like Vault.coinbase.com. Any operation related to Exchange accounts must be performed via the official application or website.
I expressed my concerns about Mason and emphasized that I would only work through the official application. He claimed that the application operation could cause a 48 -hour delay and the account closes after 24 hours. I refused to make a hurry again, so he said that the matter would be enhanced to level 3 support
