A recent piece in the Financial Times drew attention to the potential for short sellers to drive down a company’s share value by conspiring with hackers to attack a target company’s IT systems. The author of the article made the urgent but underappreciated observation that the number of malign actors capable of sophisticated hacking has proliferated in recent years, in large part because rogue states have been willing to sell or provide such capabilities to financial criminals looking to reap a windfall.
As an investigative firm with extensive experience dealing with both cyber and short selling investigations, it’s our view that the threat of cyber-enabled short selling is very real. Unscrupulous securities traders have proven all too eager to conspire with hackers to secure an illegal advantage in the market. According to a federal indictment, between 2010 and 2015, a group of hackers pilfered documents detailing transactions involving publicly traded companies ahead of their public announcement and shared them with co-conspirators. The latter, among them SEC registered broker-dealers, leveraged the not-yet-public information to make trades in the underlying stocks, while cutting the hackers in on a share of the profits. The same scheme could easily be adapted to short selling, with the added advantage (from the criminals’ point of view) that advance knowledge of a hacking attack is easier to conceal than receipt of confidential documents.
Recent market trends have created favorable conditions for such a cyber/short-attack scheme. Major US stock indices have reached record highs, setting up many stocks for a precipitous drop in price should the company suffer a cyber attack. In addition, initial public offerings have been coming at a record clip as companies list their shares directly on exchanges or go public via special purpose acquisition companies (SPACs), increasing the number of targets for cyber-enabled short selling. Finally, pandemic-induced changes to business operations, including expanded reliance on remote work platforms, have increased companies’ vulnerability to being hacked.
Who is Vulnerable? Not Necessarily Who You’d Think.
Firms whose business models don’t depend on protecting trade secrets or sensitive data could be forgiven for thinking they aren’t in the crosshairs of hackers and their short selling accomplices. The notion that if we don’t have anything worth stealing, we won’t be hacked has gone out the window with the rise of ransomware.
Ransomware attackers profit not by selling stolen data, but by crippling corporate networks and holding a company’s operations hostage until it pays the attackers a hefty sum. Such attacks have proven quite lucrative for hackers, but that may change as US authorities threaten sanctions against organizations, ranging from banks and insurance companies to incident response consultancies, that facilitate victims’ ransomware payments to these criminals. Shorting offers hackers a way to profit from their handiwork without having to secure a ransom payment or find a buyer for stolen data. If their attacks drive down the share price of their victims, they’re in the money.
Ironically, the targets of such a ransomware-enabled short attack may be those firms least concerned about being hacked. Why go after a company that has invested in cyber defenses to defend its data when you could attack one that has left its IT infrastructure unguarded?
For this reason, the companies most at risk of cyber-enabled short sellers are young, growth-oriented firms whose cyber defenses are lagging those of their more mature counterparts. Attaining effective IT security takes time and money and there are no shortcuts. Security cannot be bought off the shelf and only comes about through governance, investments in people and technology, and senior management’s commitment to creating a culture of security. In the pursuit of rapid growth, some companies may have had neither the time nor inclination to prioritize security. Indeed, they may have shunned security improvements as a drag on their agility and creativity.
What Can Companies Do?
While short sellers often publicize the reasons for their position in order to move the market, they are obviously unlikely to advertise when they have illegally coordinated or carried out a cyber attack. To that end, cyber short selling investigations require three key steps:
Of course, rather than investigate after the fact, companies should look to how they can minimize their exposure to these types of attacks. Companies at risk can take the following steps to prepare for and plan their response to cyber-enabled short selling:
Collusion between short sellers and hackers poses steep risks for publicly traded companies and their shareholders. Planning and prevention are key: mitigating these risks hinges on not selling short the creativity and sophistication of today’s cyber criminals.
