Based on the fact that the card records only contained CP (Card Present) details, this automatically rules out web-based skimmers (Magecart scripts) installed on online stores.<\/p>\n<p>Possible sources of where crooks may have obtained the card records include (1) malware installed on Point-of-Sale (PoS) systems at stores or restaurants; (2) a breach at a bank, payment provider, or PoS company; or (3) card skimmer devices installed on ATMs or PoS terminals.<\/p>\n<p>However, because EMV cards are widely adopted in South Korea, the third source seems very unlikely.<\/p>\n<h3>Cards from South Korea and APAC countries are in high-demand<\/h3>\n<p>The Gemini team also points out that there was a high demand for South Korean card data on cybercrime forums before this recent dump, which might have triggered cybercrime groups going after South Korean targets, and indirectly causing the current breach.<\/p>\n<p>This high demand also explains why crooks are selling this payment card dump at a higher price than before.<\/p>\n<section class=\"sharethrough-top\" data-component=\"medusaContentRecommendation\" data-medusa-content-recommendation-options=\"{&quot;promo&quot;:&quot;promo_ZD_recommendation_sharethrough_top_in_article_desktop&quot;,&quot;spot&quot;:&quot;dfp-in-article&quot;}\">\n<\/section>\n<p>&#8220;The median price per record from this spike is $40 USD, which is significantly higher than the median price of South Korean CP records across the dark web overall, which is approximately $24 USD,&#8221; <a href=\"https:\/\/geminiadvisory.io\/south-korean-breach-exposes-over-1-million-payment-cards\/\" target=\"_blank\" rel=\"noopener noreferrer\">Gemini researchers said in a report published today<\/a> and shared with <em>ZDNet<\/em>. &#8220;This sudden influx in card supply may be highly priced in an attempt to capitalize on the growing demand.&#8221;<\/p>\n<p><span class=\"img aspect-set\"><img decoding=\"async\" src=\"https:\/\/www.zdnet.com\/article\/breach-alert-in-south-korea-after-1m-card-details-were-put-up-for-sale-online\/\" class=\"lazy\" alt=\"South Korean card details\" data-original=\" https:\/\/zdnet3.cbsistatic.com\/hub\/i\/2019\/08\/01\/920c60e5-6bfb-447c-b212-a33f0a09e469\/e9b40571de401902400884d7a98b6534\/korea.png\"><\/span><noscript><\/p>\n<p><span class=\"img aspect-set\"><img decoding=\"async\" src=\"https:\/\/zdnet3.cbsistatic.com\/hub\/i\/2019\/08\/01\/920c60e5-6bfb-447c-b212-a33f0a09e469\/e9b40571de401902400884d7a98b6534\/korea.png\" class alt=\"South Korean card details\"><\/span><\/p>\n<p><\/noscript> <span class=\"credit\">Image:Gemini Advisory (supplied)<\/span><\/p>\n<p>In an email to <em>ZDNet<\/em>, Christopher Thomas, a security researcher with Gemini Advisory, explained why cybercriminal groups have been recently focusing on South Korea, and the Asia-Pacific region as a whole, in recent years.<\/p>\n<p>&#8220;The demand for payment card data issued by the APAC banks has always been high,&#8221; Thomas told <em>ZDNet<\/em>. &#8220;Since many of these financial institutions have less sophisticated antifraud systems than their Western counterparts, cybercriminals learned that the return on investment for APAC cards is much higher when compared to North American cards.<\/p>\n<p>&#8220;Disturbingly enough, it appears that hackers have learned that South Korean payment infrastructure is especially vulnerable to attacks, which resulted in the massive breach that is currently unfolding,&#8221; Thomas added.<\/p>\n<h3>Source of the breach won&#8217;t stay a mystery for long<br \/><\/h3>\n<p>This entire case is similar to a report from February, this year, when security researchers from Group-IB found <a href=\"https:\/\/www.zdnet.com\/article\/credit-card-details-worth-nearly-3-5-million-put-up-for-sale-on-hacking-forum\/\" target=\"_blank\" rel=\"noopener noreferrer\">card records for 2.15 million US citizens<\/a> on an underground carding forum.<\/p>\n<p>A month later, that card dump was linked to a <a href=\"https:\/\/www.zdnet.com\/article\/card-breach-reported-at-buca-di-beppo-planet-hollywood-and-other-restaurants\/\" target=\"_blank\" rel=\"noopener noreferrer\">breach at Earl Enterprises<\/a>, a US company that owns several restaurant chains such as Planet Hollywood and Earl of Sandwich, which admitted to hackers breaching its IT network and planting PoS malware at various restaurants.<\/p>\n<p>For now, the mystery of where these South Korean card details came from remains unsolved. However, this won&#8217;t remain a mystery for longer.<\/p>\n<p>As card-cloning groups start buying and using the cards, owners will start reporting fraudulent activity, and authorities will eventually track down the common payment handler in all of the victims&#8217; reports.<\/p>\n<h3>Related malware and cybercrime coverage:<\/h3>\n<p>READ MORE <a href=\"https:\/\/www.zdnet.com\/article\/breach-alert-in-south-korea-after-1m-card-details-were-put-up-for-sale-online\/#ftag=RSSbaffb68\">HERE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Source of the card records remains a mystery.
