The 17-year-old boy from India claims he has so far reported fifteen security leaks to Erasmus University. He told us in an e-mail why he does this kind of work. \u201cI\u2019m not going to be diplomatic about it,\u201d he wrote. \u201cI\u2019m doing it for the money, the freebies and the recognition!\u201d<\/p>\n<p>Batham is by no means the only hacker who contacts the university for so-called responsible disclosures. The team that follows up on such disclosures \u2013 ICT officers Richard van Schaijik, Assad Baig and Sebastiaan Kamp \u2013 spends a lot of time dealing with hackers. A responsible disclosure is a strict procedure to address a security issue in the university\u2019s systems in a legal and damage-free way. As long as the hacker complies with this procedure, his hack is considered an <em>ethical<\/em> hack.<\/p>\n\t<div data-name=\"acf\/featured-text\" class=\"md:mt-6 p-4 md:p-6 lg:p-8 bg-sand-300 theme-sand:bg-white theme-violet:bg-white theme-mocha:bg-white wysiwyg *:last:mb-0!\" >\n\t\t<p><img decoding=\"async\" style=\"float: left; height: 16em; margin-right: 1em; margin-bottom: 1em;\" src=\"https:\/\/s3-eu-west-1.amazonaws.com\/erasmus-magazine\/app\/uploads\/2018\/06\/11113932\/FB_IMG_15280938986848503.jpg\" alt=\"Devansh Batham\" \/><strong>Ethical EUR hacker: Devansh Batham<\/strong><\/p>\n<p>Batham is a first-year computer science student from India. He hunts for security issues in his spare time. Sometimes he will study a target for ten to fifteen days. He claims to have made many responsible disclosures. \u201cTo more than sixty companies!\u201d he writes, proudly. He is listed twice in EUR\u2019s Hall of Fame. Among other things, he drew EUR\u2019s attention to cross site scripting (XSS), a security issue where hackers can execute their own scripts on the victim&#8217;s website.<\/p>\n\n\t<\/div>\n<h2 class=\"wp-block-heading\">Focused search<\/h2><p>EUR\u2019s website <a href=\"https:\/\/www.eur.nl\/en\/campus\/security-safety\/information-security\/responsible-disclosure\">explains in detail how to go about it<\/a>. \u201cIt is important that the hackers perform a focused search, rather than scanning our entire system every day, so as to prevent the system from overloading,\u201d explains Richard van Schaijik. Furthermore, hackers must not collect more evidence than is strictly necessary to notify the university of a problem. \u201cFor instance, a SQL injection leak might allow them to perform database commands that would allow them to download the entire database from the site very easily. However, they can also simply download one line from this database, which is enough to demonstrate that the site can be breached.\u201d<\/p>\n<p>If a hacker finds a bug, he can report this through a webform. He must explain how he found the bug, so that Van Schaijik and his colleagues can reproduce the problem.<\/p>\n\t<div data-name=\"acf\/featured-text\" class=\"md:mt-6 p-4 md:p-6 lg:p-8 bg-sand-300 theme-sand:bg-white theme-violet:bg-white theme-mocha:bg-white wysiwyg *:last:mb-0!\" >\n\t\t<p><strong>Ethical hacker: Eusebiu Blindu<\/strong><\/p>\n<p>Blindu lives in the Czech Republic, but was born in Romania. He regards the search for bugs as some kind of investigation, \u201dlike I\u2019m an investigative journalist or detective\u201d. Being an experienced ethical hacker \u2013 \u201cha ha, I\u2019m old, I\u2019m 35!\u201d \u2013 he mainly chases financial rewards, but appreciates any present he gets. \u201cEUR\u2019s present arrived nicely wrapped up.

Sometimes the department is completely inundated, for instance because several hackers report a security issue at the same time \u2013 let\u2019s say, when they have found a bug in the software used by the university. \u201cSince we understand the technology reasonably well, it generally doesn\u2019t take us too long to determine the gravity of the problem.\u201d<\/p>\n<p>The bugs often aren\u2019t serious. In nearly half of all cases, the reports concern minor risks. \u201cSecurity always leaves some room for improvement, but sometimes it\u2019s not worth taking that additional step. In such cases we accept the risk.\u201d As for the other half of disclosures, these leaks have generally been reported before. \u201cWe only thank the first person to report an important issue by sending him a gift set and listing his name in our Hall of Fame.\u201d<\/p>\n\t<div data-name=\"acf\/featured-text\" class=\"md:mt-6 p-4 md:p-6 lg:p-8 bg-sand-300 theme-sand:bg-white theme-violet:bg-white theme-mocha:bg-white wysiwyg *:last:mb-0!\" >\n\t\t<p><img decoding=\"async\" style=\"float: left; width: 16em; margin-right: 1em; margin-bottom: 1em;\" src=\"https:\/\/s3-eu-west-1.amazonaws.com\/erasmus-magazine\/app\/uploads\/2018\/06\/11113941\/9OAakYW.jpg\" alt=\"De kentekenplaat die Dave Jong van de RDW kreeg\" \/><\/p>\n<p><strong>Ethical hacker: Dave Jong<\/strong><\/p>\n<p>Jong is a Dutch security expert who has so far disclosed two bugs to EUR. He mainly does it because of the \u201dadrenaline rush you experience when, after searching for hours, you find a leak that must be closed by the webmaster very quickly\u201d. But he also wishes to help companies and organisations keep their services secure. \u201cSome black hat hackers like to cause as much damage as possible, but I can\u2019t for the life of me understand the use of that.\u201d Bounty-hunting is a hobby to him. So far he has received a grey hoodie, a personal letter, a mouse pad and a pencil from EUR. His coolest freebie is a number plate issued by RDW, the Dutch vehicle registration authority (see image).<\/p>\n\n\t<\/div>\n<h2 class=\"wp-block-heading\">CV-building<\/h2><p>Sometimes this results in friction with proud hackers. \u201cIn such cases we\u2019ll have a difference of opinion. Generally they remain friendly, but they do sometimes push pretty hard,\u201d Van Schaijijk says, reminiscing. \u201cI understand why, because such listings are very important to them. They are building CVs with links to recognised disclosures, such as our Hall of Fame. This will give them a better shot at a job in ICT security.\u201d<\/p>\n<p>Van Schaijik occasionally discloses issues himself, \u201cparticularly to universities I know use the same software we do\u201d. The disclosures come from all over the place. A lot of them come from India, but sometimes they will come from the Netherlands. \u201cWe even receive disclosures from the university\u2019s own students and staff, or from security companies who wish to get their foot in the door at Erasmus University.\u201d<\/p>\n<h2 class=\"wp-block-heading\">Website hack<\/h2>\n\t<div data-name=\"acf\/quote\" class=\"align\" >\n\t\t<div class=\"\">\n\t\t\t<figure data-component=\"quote-with-author\" class=\"@container\">\n\t<blockquote class=\"text-md italic @2xl:text-xl @4xl:text-2xl text-purple\">\n\t\t\u2018We didn\u2019t find out until we received a disclosure from one of those hackers.

This happened a month after Schaijik commenced employment at the university. \u201cThat was a very interesting time. A lot of things changed, and we were able to implement many security measures. So in the end, it wasn\u2019t all bad.\u201d<\/p>\n<p>Ironically, the hack might have gone unnoticed if it hadn\u2019t been for the ethical hackers. \u201cWe didn\u2019t find out until we received a disclosure from one of those hackers. By then it had already happened.\u201d The question arises as to whether otherwise the university would have realised that personal data, including students\u2019 medical records, had been inspected by hackers. Van Schaijik does not really want to discuss this, though. \u201cI think I\u2019ve already said too much on this subject.\u201d<\/p>\n\n\t<div data-name=\"acf\/persons\" class=\"mt-6 md:mt-8
