Inside a Business Email Compromise Operation

Posted on by

A new report from cybersecurity company Agari’s Cyber Intelligence Division outlines the operations of a business email compromise (BEC) gang in West Africa, showing that criminals who engage in BEC online theft can have a diverse portfolio of online criminal activity that they use to build their capabilities, and use sophisticated methods to scam their victims, including businesses and government agencies.

BEC is a cyberfraud tactic in which a scammer will contact a target using phishing emails imitating a fellow employee of the target (often someone in the finance department or management) usually seeking to convince the victim to conduct a business transaction, most likely a money transfer to an account run by the scammer. The scammers may also try to trick their victims into clicking a link in an email or visiting a scam website, which could provide the scammers with the victim’s online credentials or download malware onto the victim’s computer and gain access to their company’s network.

As Risk Management previously reported, Beazley Breach Response Services found that BEC-related attacks cost victims an average of $70,960, but the FBI’s Internet Crime Complaint Center has estimated that the total “revenues” of BEC attacks doubled in 2018 to $1.3 billion. BEC attacks are also extremely common—approximately two-thirds of IT executives are reportedly dealing with them.

Agari’s report, titled “Scattered Canary: The Evolution of a West African Cybercriminal Startup,” shows that cybercriminal gangs diversify their criminal schemes, using their established infrastructure from one type of scam to facilitate others. Agari researchers named the group Scattered Canary and compared it to a tech startup because of its recruitment and expansion strategy. Scattered Canary has pursued a variety of different criminal social engineering efforts, including:

  • Romance scams: Creating a fake online romantic relationship with a victim and requesting gifts, access to their bank or retirement accounts, or services related to other scams.
  • Check fraud: A scammer offers to purchase an item for more than its advertised price with a check (which is fraudulent), then requests that the seller send the extra amount to a third party (a fictional shipping company, for example).

  • Credential harvesting: Tricking victims into providing their online credentials, including log-in information for online financial services.

Agari says that Scattered Canary built up a network of members and the skills to easily transfer from one scheme to another.

The group has used multiple BEC tactics over time, transitioning from tricking employees into carrying out wire transfers from their companies’ bank accounts to convincing victims to buy gift cards that scammers would then cash out via cryptocurrency exchanges.

More recently, the group has targeted human resource departments to change the direct deposit information for a company’s executive, then cashed out the deposits using prepaid debit cards.

Businesses should train their staff at all levels on how to spot BEC and other types of online scams. If employees can recognize phishing emails and websites, and know not to click links or provide information in response to either, this can protect companies from fraud and significant financial loss. In addition to training staff, the FBI suggests always verifying requests to send money, even if the email requesting the transfer is urgent, by speaking directly to the person who seems to be requesting the money on the phone (using the previously known number, not the one provided in the email) or in person. The FBI also suggests setting up filters that flag email addresses that are similar to the company’s email, and creating an email rule that notes emails coming from outside the company, among other technical steps.

Microsoft Vulnerability A Reminder to Update and Patch

Posted on by

Microsoft recently announced a major vulnerability to Windows XP, Windows 7 and several older Windows server versions. According to Simon Pope, the company’s director of incident response, “[A]ny future malware that exploits this vulnerability could propagate from vulnerable computer to vulnerable computer in a similar way as the WannaCry malware spread across the globe in 2017.” This announcement reinforces the importance of companies patching security vulnerabilities to mitigate the risk, especially on older machines that still serve essential functions.

This news follows a TechCrunch article reporting that at least a million computers worldwide, mostly in the United States, remain vulnerable to the WannaCry and NotPetya malware because users have not installed the necessary patches. Cybercriminals continue to use this malware, based on hacking tools originally developed by the NSA, to deliver all sorts of malicious software to unsuspecting victims online.

WannaCry is ransomware—malicious software that hijacks a computer and demands payment to regain control—that quickly spreads and has affected businesses, government and individuals in over 150 countries since 2017. Around the same time, a malicious software disguised as ransomware called NotPetya spread worldwide, affecting global business operations, and effectively paralyzing multiple companies in what has been called “the most devastating cyberattack in history.” Both caused massive financial damage worldwide, with WannaCry estimated at $8 billion in damages and NotPetya estimated at $3 billion.

Windows has released patches to protect systems from the newly announced vulnerability, even for Windows XP and Windows Server 2003, despite the company not usually offering support for those older systems.

However, XP users will have to manually download the patches from Microsoft’s update website. According to a 2017 Spiceworks study, businesses worldwide were still running Windows XP on 11% of their laptops and desktops. While that has likely decreased in the past two years, it would still leave a significant number of machines running exposed systems that require manual updates to patch.

Not patching vulnerabilities has led to serious incidents, like the Equifax breach in 2017, which led to the theft of 143 million Americans’ personal information.

In that case, the US Department of Homeland Security had issued a warning about the vulnerability, a patch for a web application vulnerability had reportedly been available for 2 months before the breach, and Equifax failed to implement the fix. A US House Oversight Committee report blamed the company entirely, saying that Equifax “failed to implement an adequate security program to protect this sensitive data,” and that “such a breach was entirely preventable.”

Companies use numerous different types of software in their daily operations, and software providers issue many patches for their products, which leaves companies overwhelmed. According to an April 2018 Ponemon Institute study, 68% of companies “find it difficult to prioritize what needs to be patched first.” IT staffing limitations and competing priorities within organizations can hinder these efforts, since patching requires heavy time investment and sometimes taking important aspects of the business offline to implement fixes. Companies with third-party partners and supply chains face even more complex risks, since their systems are often integrated or dependent, and companies likely do not have direct control over partners’ systems to ensure patching. Mitigating outside risk by including in contracts stipulations that third-party partners meet certain security requirements can also help.

Companies Must Evolve to Keep Up With Hackers

Posted on by

If you ask a CFO if their company’s current cybersecurity strategy is working, it’s very likely that they do not know. While at first they may think it is, because the company’s bank accounts are untouched, an adversary could be lurking in their network and collecting critical data to later hold for ransom—threatening to destroy it if the money isn’t paid. The truth is that many organizations are lacking effective risk management that ensures the integrity and availability of their most essential data.

Corporate America needs to take the power back and stop hackers before they compromise networks and exfiltrate data for criminal uses, or simply threaten to destroy it for financial gain. To shift the power back in their favor, they must safeguard data, implement an effective risk management program, and invest in risk reduction activities. Organizations need to assess the maturity of their cybersecurity efforts, determine if they have any pre-existing conditions, and focus on risk reduction efforts that truly protect their data, while ensuring the ability to deliver products and services.

The fastest way to check for pre-existing conditions is by doing a compromise assessment to identify any current suspicious activity within their network. From there, they can determine what exactly needs to be done to reduce their organization’s cyber risk and develop a risk management plan that outlines clear steps for protecting their most critical assets.

To develop a cybersecurity risk management plan, executives need to first define the company’s “crown jewels”—the things that if compromised, would cause the most damage or inhibit the ability to deliver products or services that generate revenue. For instance, for a bank, this could be access to funds by their individual or business customers, or banking information that could be used for fraudulent purposes. Once an organization knows what it’s protecting, the executives can then create a security roadmap that ensures the secure delivery of products or services.

The security roadmap should start with a business impact assessment that identifies those crown jewels that are needed for delivery of essential services or producing products. These can include the data itself, technical architecture or systems used by their customers to transact business. Once these have been identified a prioritized risk reduction plan needs to be developed and tracked by the company’s leadership. Every facet of risk should be considered, from legal risk, to the consequences of a data breach, or inability to deliver services resulting from an intrusion or denial-of-service attack.

While security assessments and roadmaps are essential for defining an organization’s adequate cyber defenses, one of the biggest mistakes we see businesses make is being reactive when it comes to their defenses—relying on traditional technologies that only identify known threats and leverage Indicators of Compromise (IoCs). This method does not capture new exploits fast enough, nor versions of malware or other obfuscation techniques that are introduced by sophisticated adversaries. A great example is the sheer speed at which WannaCry ransomware spread to organizations of all sizes across the globe. Adversaries are capitalizing on this reactive security shortcoming by taking advantage of this window of opportunity to comprise data or networks.

Instead, organizations must take a proactive approach that focuses on indicators of attack (IoAs) that identify adversary behavior indicating malicious activity, such as code execution or lateral movement. IoAs can alert businesses to adversary activity before any damage is done. To effectively make use of this data, businesses also need to leverage threat intelligence for deeper insights into these IoAs.

Threat intelligence provides a crucial layer of information on adversary motives, tactics, techniques and procedures. For instance, a bank could look at a threat and see if this particular adversary typically targets the financial services industry, which regions they operate in and the motive behind their attacks.

Going one step further, organizations should leverage technology that enables threat intelligence to be shared rapidly and can protect numerous customers at once. At the end of the day, effective security requires a community effort.

Corporate America needs to come together and truly leverage the power of crowdsourced intelligence—to keep from becoming victims of the next big attack.

From a lack of risk management plans, to reliance on reactive security measures, there are a number of areas where companies are falling short of having an adequate cyber defense. By putting the necessary plans in place to secure the integrity of their critical data, taking a proactive approach to cyber threats and working together across industries and businesses, corporate America can collectively build a stronger cyber defense.

New York Cybersecurity Regs to Take Effect March 1

Posted on by

The state of New York is implementing sweeping new regulations designed to protect insurers, banks and others from the growing wave of electronic security breaches which are making headlines and causing headaches across the financial services industry.

The new rules, slated to take effect March 1, mandate that insurers, banks and other financial services institutions regulated by the Department of Financial Services (DFS) establish and maintain a cybersecurity program. In addition to setting program standards, the 12-page document also provides definitions for companies as well as laying out “Transitional Periods” of 180 days to two years for companies to comply with different parts of the conditions and parameters of the regulations.

Entities must create and maintain written policies, requiring board-level or equal approval, setting out the company’s cybersecurity plan. Companies also must designate a chief information security officer (CISO), either in-house or third-party, who will be required to report annually to the company’s board.

The rules call for stress testing of systems and periodic risk assessment and for the inclusion of third party service providers in a company’s cybersecurity plan.

The regulations will be published in the New York State register on March 1 and lay out the Department’s logic in establishing the new standards.

According to the document:

“The New York State Department of Financial Services (DFS) has been closely monitoring the ever-growing threat posed to information and financial systems… Given the seriousness of the issue and the risk to all regulated entities, certain regulatory minimum standards are warranted, while not being overly prescriptive so that cybersecurity programs can match the relevant risks and keep pace with technological advances… It is critical for all regulated institutions that have not yet done so to move swiftly and urgently to adopt a cybersecurity program and for all regulated entities to be subject to minimum standards with respect to their programs.”

New York’s regulatory framework is the first of its type in the nation, according to a release from the Governor’s office.

“New York is the financial capital of the world, and it is critical that we do everything in our power to protect consumers and our financial system from the ever-increasing threat of cyber-attacks,” Governor Andrew M. Cuomo said in the statement. “These strong, first-in-the-nation protections will help ensure this industry has the necessary safeguards in place in order to protect themselves and the New Yorkers they serve from the serious economic harm caused by these devastating cyber-crimes.”

Under development since 2014, proposed new regulations were first published in September 2016, followed by a 45-day comment period. Updated proposed regulations were then published in December 2016, followed by a 30-day period for comments. Then in December, N.Y. state delayed implementing the rules and subsequently adjusted some requirements to reflect input from the industry, which asserted the rules were burdensome and said they would need more time to comply.

In addition to these accommodations, DFS took measures not to burden smaller businesses by establishing limited exemptions for companies with fewer than 10 employees, less than $5 million in gross annual revenue in each of the last three fiscal years from New York business operations, or less than $10 million in year-end assets.

According to the statement from the Governor’s office, the new regulations mandate:

• Controls relating to the governance framework for a robust cybersecurity program including requirements for a program that is adequately funded and staffed, overseen by qualified management, and reported on periodically to the most senior governing body of the organization

• Risk-based minimum standards for technology systems including access controls, data protection that includes encryption, and penetration testing

• Required minimum standards to help address any cyber breaches including an incident response plan, preservation of data to respond to such breaches, and notice to DFS of material events

• Accountability by requiring identification and documentation of material deficiencies, remediation plans and annual certifications of regulatory compliance to DFS

While cybersecurity has become an outsized concern for many business as high-profile breaches have played out in the media, sometime drawing in millions of consumers and costing companies millions of dollars in addition to precious reputational damage, many businesses remain under—or unprepared—for the challenges posed by cyber threats.

Indeed, The Hiscox Cyber Readiness Report 2017 surveyed managers and IT specialists at 3,000 small to large companies in the U.S., U.K. and Germany and found that just over half, 53%, of businesses are ill-prepared to deal with cyber-attacks. The study ranked companies from novice to expert in four key areas: strategy, resourcing, technology and process. Only 30% qualified as “expert” in their overall cyber readiness, of which 49% were U.S.-based companies.
