Guarding Against PoSeidon and Other Point-of-Sale Breaches

According to Cisco’s Security Solutions team, there is a new malware family targeting point-of-sale (PoS) systems, infecting machines to scrape memory for credit card information and send the payment card data to servers for harvesting and, likely, resale. This malware, which the group has nicknamed PoSeidon, works like this:

Unlike other PoS memory scrapers that store captured payment card data locally until attackers log in to download it, PCWorld reported, PoSeidon communicates directly with external servers and can update itself automatically, and also has defenses against reverse engineering.

PoS malware using the “memory scraping” technique also caused the Home Depot and Target data breaches. In the latter, hackers were able to save names, credit card numbers, expiration dates, security codes from the backs of cards and encrypted PINs when at least 40 million customers swiped at in-store registers.

“The new PoSeidon malware has retailers on alert, particularly as the frequency and relative ease with which POS system breaches are occurring is forcing them to take a closer look at their IT infrastructure and reassess how secure it actually is,” said Andrew Avanessian, EVP of consultancy and technology services at security firm Avecto. “It is also prompting many to ask, what will it take to get ahead of these attacks?”

Avanessian believes the answer is clear: a more defense-in-depth approach to security. “While perimeter technologies like firewalls can prevent against certain types of external attack, it cannot block malware that has already found its way onto endpoints within an organization,” he explained.

“With a multi-layered security strategy that incorporates solutions like patching, application whitelisting and privilege management, organizations can more effectively protect against the spread of malware, defending their valuable assets and ultimately their reputation.”

As I wrote in the March 2014 issue of Risk Management, the adoption of EMV chip technology presents one of the most promising ways to increase PoS security. Already common in Europe, EMV technology—named for its founders, Eurocard, MasterCard and Visa—utilizes embedded chips that, unlike magnetic strips, make it nearly impossible to counterfeit cards. In Europe, 81% of cards have EMV chips, and countries that have adopted the technology saw sharp declines in credit card fraud. Meanwhile, the United States accounts for 27% of worldwide credit transactions, but sees 47% of card fraud.

As organizations roll-out chip and pin technology across the country, these breaches may start to decline, Avanessian agrees, but he urges a more holistic approach to fighting PoSeidon and other PoS malware. “EMV (or chip-and-pin) will absolutely help stop card fraud, however, retailers should not become complacent and think this is the silver bullet they have been waiting for,” he said. “Yes it will help stop fraud once the details have been stolen, but it does not stop businesses from being breached. Companies gather a huge amount of data about their patrons, such as names and addresses, and this data is still valuable to fraudsters.

Unless retails take a multi-layer defense-in-depth approach to security, they will still get breached.”

To prevent consumers from losing and shopping elsewhere, Avanessian believes it is critical to evolve the means of combatting cyberattack just as the means of hacking has changed. “In our experience, retailers are still relying on antiquated ‘detection’-based technologies to keep the bad guys out. They all spent hundreds of thousands of dollars on detection, yet they still get breached,” he said.

“The world has changed, the players have changed, cyberattacks are now a trillion dollar industry—the approach has to change.”

Engaged Boards Lead to Better Information Security Practices

Board of Directors

According to a new study from Protiviti, engagement by a company’s board of directors is a critical factor in best managing information security risks.

Overall, engagement and understanding of IT risks at the board level has increased, yet one in five boards still have a low level of comprehension. As the report states, this suggests “their organizations are not doing enough to manage these critical risks or engage the board of directors in a regular and meaningful way.” Further, while large companies do exhibit stronger board-level engagement, it is not a dramatic distinction.

Overall engagement data

Of those companies that have implemented all core security policies—an acceptable use policy, record retention and destruction policy, written information security policy (WISP), data encryption policy, and social media policy—78% have boards with a high or medium level of engagement on information security. Even rudimentary security measures appear to vary with board engagement. Three out of four organizations with engaged boards have a password policy, while just 46% of those with medium or low levels of engagement have this basic provision in place.

IT Security Measures

The study did find two particularly alarming trends, both in companies with and without risk-aware boards. There was a significant increase this year in the number of organizations without a formal, documented crisis response plan to address data breach or cyberattack. Further, a surprising number of companies still do not have core information security policies. “One in three companies do not have a written information security policy (WISP). More than 40% lack a data encryption policy. One in four do not have acceptable use or record retention/destruction policies. These are critical gaps in data governance and management, and ones that carry considerable legal implications,” the report states. “On the other hand, organizations with all of these key data policies in place have far more robust IT security environments and capabilities.”

 

The Evolving Cyberrisk Landscape and the Insurance Industry

Cyberrisk

Rapidly developing computer technologies and the unrelenting evolution of cyberrisks present one of the biggest challenges to the (re)insurance sector today. Liabilities from cyberattacks and threats to the data security of cloud computing and social media have become key emerging risks for carriers. The unprecedented rise in cyberattacks, in addition to the threat cyberrisk poses to global supply chains, has seen the cyberinsurance market grow significantly in recent years.

Client demand for cyber coverage has been growing, on average, 30% annually in the United States over the past several years, according to Marsh. While demand varies by industry, the one constant has been that more clients are investigating and analyzing existing traditional insurance coverage and whether they need standalone cyberrisk insurance coverage.

Because cyberrisk is associated with the use of technology and the handling of all data and information, the threat transcends a company’s information technology (IT) department as well as what is confined to the internet. To help overcome some misconceptions that still exist for cyberrisks, some clarity around business exposures is needed to understand the scope of the threat.

Cyberattacks pose a danger to global supply chains

Cyberrisks are not isolated and are usually connected to other risks. Many companies that are exposed to cyberrisks are, for example, also exposed in turn to risks to their supply chain. Due to technological innovation and advances, many parts of a company’s or industry’s supply chain have become interconnected and automated.

Most commercial entities today are exposed to these risks as a growing number of businesses become more interconnected globally. A single cyberattack has the potential to put an entire company’s supply chain at risk. Therefore, cybersecurity and supply chain risk management must be considered in conjunction with one another.

There are a range of risks when it comes to online/computer security. Cyberattacks can result in first party liability, including business interruption, computer security breaches, privacy breaches of confidential information and even third-party liability losses. Technology failures have begun to outpace adverse weather, fire and social unrest as the major force in disrupting a corporate supply chain, according to a recent Guy Carpenter report.

Everyone is at risk – individuals, companies and governments

In 2014, cyber issues have become more of a concern for companies that once felt they had relatively little exposure. In fact, cyberattacks were ranked fifth among the top five global risks in terms of likelihood in this year’s World Economic Forum’s annual Global Risks 2014 report.

Governments consider cyberattacks to be among the most serious economic and national security challenges now facing them. And through the ubiquitous use of the internet, mobile devices and social media, companies of all sizes and in all nations are now finding themselves at risk of falling prey to the full range of cyber perils. Such attacks can run from hackers shutting down a company’s network, gaining access to customers’ and employees’ personal and financial information, to the theft of business trade secrets.

More data laws and regulations in place

High-profile data breaches and other cybersecurity incidents have become more commonplace with increasingly onerous outcomes. Target, one of the largest retailers in the United States, suffered a massive cyberbreach late last year which involved the theft of approximately 40 million credit and debit card account details as well as personal data of nearly 70 million customers. The breach reportedly occurred when hackers used the retailer’s heating and cooling vendor’s system to navigate their way into the retailer’s records. The resulting publicity cost the company a significant amount in lost sales, loss of reputation, class action lawsuits, and may have contributed to the ouster of the chief executive officer. And most recently, a U.S.-based online auction site announced that hackers accessed the company’s 145 million user accounts and urged customers to change their passwords.

More recently, home improvement chain Home Depot became the victim of another credit card data breach and the FBI is reportedly investigating cyberattacks at some of the largest banks in the United States.

As cyber incidents affect both consumers and institutions, governments everywhere are putting more data privacy laws and regulations in place in regard to disclosure and other related safeguards. In the United States, there are laws that require the protection of both personal financial and health information. Last year, the U.S. Securities and Exchange Commission, which oversees publicly-traded companies, adopted a directive requiring certain regulated financial institutions and creditors to adopt and implement identity theft programs in light of the new cyber threats.

Risk mitigation and insurance

With governments considering and enacting new laws in response to the rising number of cyber events, companies, especially those in the United States, are taking a closer look at cyberrisk mitigation, including insurance coverage of breaches and attacks.

Media reports of serious data breaches have prompted more companies to buy cyber coverage of $100 million or more compared to the prior year, Marsh said in its March 2014 report Benchmarking Trends: Interest in Cyber Insurance Continues to Climb.

Traditional insurance products often do not cover risks that cover damages resulting from an incident like a computer breach.

As such, specific cyber liability insurance may be necessary.

The very process of applying for cyberrisk insurance is a constructive exercise for raising awareness and identifying potential vulnerabilities.

By engaging in that process, a company can perform a review of information security protocols with respect to access control, physical security, incident response and business continuity planning.

As a result, businesses and other institutions are finding that cyberinsurance products have been broadened to include coverage that now addresses nearly all aspects of technology-based risk faced by today’s companies. Carriers have been adapting their policies to include a variety of loss prevention and risk mitigation tools, ranging from turnkey breach response teams to pre-emptive risk analytics.

As cyberthreats become more severe, more frequent, and continue to change along with technological advances, the (re)insurance industry will continue to stay one step ahead by creating new forms of cyberrisk coverage to meet the needs of their clients.
