By means of these investment recommendations, cyber criminals are trying to influence the share price of a particular company\u2019s stock to their own advantage. In the current wave of attacks, the authors are calling for recipients to buy securities in the company Quest Management Inc.: <div id=\"attachment_10888\" style=\"width: 666px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/www.retarus.com\/blog\/it\/wp-content\/uploads\/sites\/4\/2017\/05\/20170428_Retarus-PR_Online_fraudsters_bank_on-stock_market_manipulation.jpg\" data-rel=\"lightbox-image-0\" data-rl_title=\"\" data-rl_caption=\"\" title=\"\"><img aria-describedby=\"caption-attachment-10888\" loading=\"lazy\" decoding=\"async\" class=\"wp-image-10888\" src=\"https:\/\/www.retarus.com\/blog\/it\/wp-content\/uploads\/sites\/4\/2017\/05\/20170428_Retarus-PR_Online_fraudsters_bank_on-stock_market_manipulation.jpg\" alt=\"Screenshot of the current version of the Spam mail (Source: Retarus)\" width=\"656\" height=\"487\"><\/a><p id=\"caption-attachment-10888\" class=\"wp-caption-text\">Screenshot of the current version of the Spam mail (Source: Retarus)<\/p><\/div> Through this scam the spammers are not only profiting from a short-term rise in the share price based on demand for the stocks, but also stand to benefit from the subsequent crash by holding options. That this logic actually adds up was clearly shown by a similar attempt at fraud in March. The <a href=\"https:\/\/www.google.com\/finance?chdnp=1&amp;chdd=1&amp;chds=1&amp;chdv=1&amp;chvs=maximized&amp;chdeh=0&amp;chfdeh=0&amp;chdet=1490299200000&amp;chddm=2346&amp;chls=IntervalBasedLine&amp;q=OTCMKTS:INCT&amp;ntsp=0&amp;ei=8DMDWenZOMWMswG0_KDADw\" target=\"_blank\" rel=\"noopener noreferrer\">share price of InCaptcha Inc.<\/a> initially sky-rocketed during a 4 day spam wave and then plummeted just as fast thereafter. The stocks recommended in these types of spam emails are mostly so-called \u201cpenny stocks\u201d, which are securities quoted at less than a dollar. <\/p>\n<h2>Fraudsters are using a world-wide botnet consisting of 400,000 computers<\/h2>\n<p> Retarus\u2019 systems alone filter out around 9.3 million of these types of spam emails on a daily basis. According to analyses done by the security experts, the current attack is being carried out by a botnet which is estimated to have hijacked 400,000 computers to do its dirty work. In the current case the spammers are proceeding extremely insidiously, as the infected systems are not paralyzed by distributing huge volumes of messages, as is usually the case. Instead, by limiting the transmission to a maximum of 50 emails per minute, their activities generally remain under the thresholds at which IT administrators would become aware of them. <\/p>\n<h2>Spam filters outsmarted by numerous text variations<\/h2>\n<p> The spammers also continually adapt and modify the text in the spam messages. The company name, for instance, was written in full in messages at the beginning of the attack, while in more recent versions only the securities identifier \u201cQSMG\u201d is mentioned in a more coded way. The recommendation to buy the stocks is also substantiated in various ways &#8211; some emails refer to a forthcoming takeover and others herald an amazing breakthrough in cancer research. So for many conventional spam filters these kinds of attacks are difficult to identify in time, as they solely rely on searching for specific keywords. That\u2019s why it is crucial to keep the signatures of the spam and virus filters up to date at all times. Retarus\u2019 specialists moreover recommend that their customers adopt a basic principle of first shifting all messages with more than 60 percent likelihood of being spam into quarantine. <\/p>\n<h2>The human insecurity factor: heightened vigilance essential<\/h2>\n<p> <a href=\"https:\/\/www.retarus.com\/blog\/it\/wp-content\/uploads\/sites\/4\/2015\/03\/warning.png\" data-rel=\"lightbox-image-1\" data-rl_title=\"\" data-rl_caption=\"\" title=\"\"><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-97 alignleft\" src=\"https:\/\/www.retarus.com\/blog\/it\/wp-content\/uploads\/sites\/4\/2015\/03\/warning.png\" alt=\"\" width=\"130\" height=\"130\"><\/a>To safeguard themselves from the dangers of such fraud attempts, it is also absolutely essential that users have increased levels of vigilance and check the plausibility of messages more attentively.

This means that companies need to take steps to sensitize their staff about these kinds of attacks on a regular basis. In the best case, real-world examples should be used to heighten awareness and transparent, easy-to-follow guidelines should be provided for cases where suspicion arises.
