Beware! This malware can steal passwords, credit card info

Global cybersecurity company Palo Alto Networks has discovered a malware that is capable of stealing saved usernames and passwords in Google Chrome, saved credit card credentials in Chrome and iPhones text messages if backed up to a Mac.

The malware named "CookieMiner" is capable of stealing browser cookies associated with mainstream cryptocurrency exchanges and wallet service websites visited by the victims, said Unit 42, an arm of Palo Alto Networks. 

It steals saved passwords in Chrome and iPhone text messages from iTunes backups on the tethered Mac.

"By leveraging the combination of stolen login credentials, web cookies and SMS data, based on past attacks like this, we believe the bad actors could bypass multi-factor authentication for these sites," the researchers noted.

If successful, the attackers would have full access to the victim's exchange account and/or wallet and be able to use those funds as if they were the user themselves.

The malware also configures the system to load coinmining software on the system. 

Web cookies are widely used for authentication. Once a user logs into a website, its cookies are stored for the web server to know the login status. 

If the cookies are stolen, the attacker could potentially sign into the website to use the victim's account.

"Stealing cookies is an important step to bypass login anomaly detection. If only the username and password are stolen and used by a bad actor, the website may issue an alert or request additional authentication for a new login," said Unit 42 in a blog post on Thursday. 

However, if an authentication cookie is also provided along with the user name and password, the website might believe the session is associated with a previously authenticated system host and not issue an alert or request additional authentication methods.
