Your WhatsApp number might be at a Risk
He said that his protection issue could have been maintained if WhatsApp numbers were encrypted and also including a robots.txt document refusing the bots from crawling on their domain and a meta noindex tag on the pages, sadly they didn’t do that yet and your security might be in question.
Jayaram additionally noted, “with a big user base, they should care about these vulnerabilities. Today your mobile number is linked to your Bitcoin wallets, Aadhaar, bank accounts, UPI, Credit cards leading an attacker to perform SIM card swapping, and cloning attacks by knowing your mobile number is another possibility.”
For example, Jayaram clarifies, if a client shares a “click to chat” connect with a companion on Twitter or some other platform his/her number will be noticeable in plain content in the URL itself, anybody who finds the URL will have the option to get hold of the number which can’t be repudiated.
The WhatsApp number will be accessible on Google considerably after the first tweet is erased. This is on the grounds that when the tweet is erased Google bot would have crawled the URL and the connection would remain on the web available to everybody around the globe.
“This is because https://wa.me does not have a robots.txt file in its server root, which means you cannot stop Google or other search engine bots from crawling and indexing the wa.me links, which means those links will stay in the web. The pages do not have noindex meta tags to prevent any search engines from indexing the links,” Jayaram said.

In addition, if the client’s WhatsApp security settings are set to the public the scammers may likewise have the option to gain admittance to your profile picture, name, profile status, and more subtleties. Not simply that cybercriminals may likewise land up calling or content informing you given they have your number as of now. Jayaram proposes that “the best way to avoid the situation may be to delete your WhatsApp account or change your mobile number.”
