This could give the criminal covert access to users\u2019 accounts and confidential data on secure websites such as Facebook, Amazon or PayPal. The reconstruction shows how this could also be possible with online banking.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No successful attack using this method against online banking is known in the Netherlands. The attack attempts to deceive inattentive users and can be effectively prevented if both banks and users remain alert.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-do-banks-do\">What do banks do?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Banks continually invest in new measures to keep banking secure. An SSL security certificate on an online banking website already provides good basic protection if users pay close attention. When users see a green padlock in their browser\u2019s address bar, they can verify that they have a secure connection to their bank. Clicking the padlock allows them to confirm that they are connected to their own bank and that all data, including access codes, is encrypted before being exchanged with the website.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The demonstrated attack concerns online banking through a standard web browser. Many banks offer smartphone and tablet apps for mobile banking. In the scenario demonstrated, banking through such an app offers greater security than using a standard browser.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Banks can also identify and prevent suspicious transactions. Transfers to familiar accounts, such as those of a landlord, sports club or municipality, are processed normally. If a transaction deviates from the account holder\u2019s usual payment pattern, for example by going to an account never used before, the bank may carry out additional checks.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-can-users-do\">What can users do?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Users can also take several precautions. To begin with, they should avoid online banking through unknown and unsecured Wi-Fi hotspots whose owner is unknown and which do not require a secure password. Users should be particularly cautious with publicly accessible hotspots.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When using a standard browser for online banking, it is advisable to connect only through a trusted and secured Wi-Fi hotspot. Mobile banking through the bank\u2019s app offers better protection against the attack described.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Users should also check the green padlock on their bank\u2019s website. During an attack, a padlock may appear on the webpage itself rather than in the browser\u2019s address bar. Depending on the browser, a fake padlock may also appear near the top of the browser where the bank\u2019s logo is normally shown. This is a warning sign: the genuine padlock must appear in the browser\u2019s address bar, in green, together with the bank\u2019s full name. Clicking it should open a pop-up showing the bank\u2019s name without any warnings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Account holders can further improve online banking security by following the banks\u2019 <a href=\"https:\/\/www.veiligbankieren.nl\/uniforme-veiligheidsregels\/\" target=\"_blank\" rel=\"noreferrer noopener\">uniform security rules (in Dutch)<span class=\"sr-only\">(opens in new window)<\/span> <span class=\"icon inline-block ml-1 w-[0.875em]\" aria-hidden=\"true\"><svg aria-hidden=\"true\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"32\" height=\"32\" fill=\"#000000\" viewBox=\"0 0 256 256\"><path d=\"M228,104a12,12,0,0,1-24,0V69l-59.51,59.51a12,12,0,0,1-17-17L187,52H152a12,12,0,0,1,0-24h64a12,12,0,0,1,12,12Zm-44,24a12,12,0,0,0-12,12v64H52V84h64a12,12,0,0,0,0-24H48A20,20,0,0,0,28,80V208a20,20,0,0,0,20,20H176a20,20,0,0,0,20-20V140A12,12,0,0,0,184,128Z\"><\/path><\/svg><\/span><\/a>.
