+30 210 48 48 484, mentioning the word "fraud".
Phishing is the attempt to steal your banking data through misleading e-mails or mobile phone messages from supposedly trusted entities. The main target is the interception of your Digital Banking access codes, as well as your bank account or credit and debit card details.
Messages such as SMS, e-mails or even phone calls (e.g., repairing an "alleged" fault) appear to come from the bank itself or from other trusted organizations and seek to mislead you and extract personal data such as your Digital Banking password and details of your bank accounts or credit and debit cards.
The bank's cotemporary identification systems as well as your proper awareness on these kinds of attempts can protect you from being a fraud victim. The bank will never ask you for your passwords through any form of message and you should never log into Digital Banking through links embedded in any message.
These messages usually include an urgent sign, but having been informed you can identify them, and stay safe.
1. The email does not originate from the National Bank of Greece domain (@nbg.gr), although the communication attempts to indicate that it is related to or originates from it.
2. There are attached files included in the emails (very often files with the extension . pdf,. zip)
3. Poor & incorrect use of the Greek language or grammatical errors are detected.
4. The content of the e-mail/sms/phone call asks you to perform a suspicious action, e.g., to go to a link and enter certain information.
5. The links contain anagrams referring to existing electronic sites, like those of the National Bank of Greece, but without belonging to the bank.
A technique in which fraudsters manage to gain access to the victim's personal data in various ways, such as through malicious applications, social media searches, etc. With this data, they deceive mobile operators to obtain a new SIM card to replace the one the legitimate holder has. Once they activate the new card, they can receive all the calls and messages of the legitimate holder to perform illegal activities. See the detailed update from the Hellenic Bank Association.
Plain text messages (SMS) sent to the mobile phones of potential victims.
The attempt to deceive is made by means of a telephone call. Very common is the attempt to deceive through an alleged repair of the device (e.g., computer, smartphone) of the potential victim by a well-known IT company. In this way, they convince their victims that the device requires intervention (e.g., repair) and install applications that allow them to control the device in order to steal the victims' personal data stored on it.
Pharming (phishing without a lure)
Hackers or some malware installed on the potential victim's computer through the browser, directing them to a virtual website.
This technique targets specific individuals. Hackers research and focus on specific targets by sending appropriately tailored emails.
Targeted e-fishing aimed at "big targets", e.g., CEOs or politicians.
Advanced jamming technique in real mail. The attacker clones a legitimate email from a trusted source. To the victim, the email or mobile message they receive appears to be a continuation of their conversation but may contain a malicious link.
1. Avoid online scams
If someone calls you from an unknown number and claims to be an employee of a well-known IT company, without you having reported a computer fault, you should terminate the call.
2. Avoid using unreliable software
Never install remote management software that may be suggested by a stranger.
3. Protect your online/social media presence
If your mobile phone stops working for unusual reasons, contact your bank and mobile phone provider immediately. Sometimes you may lose signal due to wider problems affecting your mobile phone service. However, if you lose service in a location where there is usually good network coverage, it is safer to contact both your bank and your network provider and confirm that your SIM has not been deactivated.
