Of course, I do not use it anymore. I was surprised at the speed with which the bitcoins were withdrawn. Almost instantly.

it is just a small script with a node watching this address and spending coins that it receives immediately.

However, I used the same purse in the mobile application BitPay.

i am not sure how BitPay wallet works but it got me thinking whether you actually own the private keys to those addresses?
for example you sent 0.15BTC to this address: 1JwwG2TbXxwRxV9mFg8hqKrvt3WZH4uD2j
was this address created by your Electrum wallet which has a seed or did you generate this address using BitPay and do you have access to its private key?

What about the vulnerability, when coinciding cases of opening a malicious site and purse at the same time?

this particular vulnerability existed in versions from 2.6 to 3.0.4, you said your version is 3.0.5
