Hi folks,
Following
(i) theft of approximately $1200,
(ii) a voluminous string of 1000s of identical or similar phishing emails,
(iii) unauthorized call forwarding to a designated number associated with spam,
(iv) inability to turn off call forwarding to specified number,
(v) delayed receipt of texts/calls (showing hours to days after submission),
(vi) hundreds of daily robocalls,
(vii) and a sophisticated email demanding a large sum to avoid disclosure of sensitive information purportedly collected from my device through spyware and a key-logger—which the hacker sought to prove by relaying my various passwords, contacts, website traffic, etc.,
I have executed a complete security wipe of my BlackBerry Z10, encrypted all personal data and files, set up a highly secure SSL/TLS, changed all login credentials using a secure device and third-party platform, enabled two-factor authentication, disabled unauthorized call forwarding through my ISP, and filed detailed complaints (with email headers), among other remedial things.
Should I be concerned about a malicious executable surviving the security wipe?
