If you receive an email claiming to be from Skype that you suspect is fraudulent, please DO NOT open any attachment to the email, reply to the email, or click any links in the email.
Fraudulent emails may ask you to provide your Skype password, Skype payment details, or other sensitive personal information. They may tell you that you need to upgrade or reinstall Skype, or that your order is being delivered or has been refused. For example, these are the Subject lines from previous fraudulent emails:
These emails are known as "spoof" or "phishing" emails. The people who send them hope that you will reply to the email with sensitive personal information such as your Skype password, or that you will click a link in the email to go to a fraudulent web site, or that you will open an attachment to the email that could install potentially dangerous software on your computer. If you receive an email like this, please let us know immediately by sending an email to firstname.lastname@example.org.
Genuine emails from Skype are never anonymously addressed. They will always contain your name or your Skype Name. The information they contain can either be found on the skype.com website or on your Account page.
If you send an email to Skype Customer Service, our reply may ask you to provide further account or billing information. This is normal. However, Skype will NEVER request that you send us your password.
Additionally, Skype will never make any contact with you through instant messaging to persuade you to download content or get you to part with your personal details, unless you have already contacted us. If someone contacts you pretending to be from Skype, block them and report them for abuse.
Please be extremely cautious when responding to any email request for sensitive personal information.
