As the global pandemic begins to show signs of waning, cyber risk is showing no such easing. In fact, in a recent survey, over 68% of business leaders reported believing that their cybersecurity risks are increasing, despite their own mitigation strategies. Organizations in this coming year will continue to face a constantly evolving threat landscape and increasing threat actor sophistication. Catastrophic supply-chain breaches in 2020 have made organizations begin rethinking what devices, software, and hardware is trustworthy in their environments. While nation-state actors with significant resources appear to have carried out the recent major supply chain attack(s), even “script kiddie” threat actors are expanding their capabilities and improving their techniques. Several trends are on the horizon for this next year. They are as follows:
Ransomware Is Evolving to Data Exfiltration and Extortion
Historically, ransomware focused on infiltrating organization endpoints and locking the organization out of their own data. While temporarily paralytic, organizations generally made it through those events by either paying the ransom, or recovering their data from disaster recovery or backup media. Tactics have changed for many ransomware threat actors, however, and now many seek to exfiltrate data in addition to deploying ransomware. They do this so that if an organization fails to pay the ransom amount, then they can fall back on the exfiltrated data to extort the organization. If the organization still fails to pay the new extortion ransom, the data is then leaked, usually on the Dark Web. In the first instance, effective incident management with experienced professionals is critical to managing your way through the incident. In the event of disclosure of data, there are also many issues that arise including potential disclosure of attorney-client communication, work product, trade secrets, and PHI/PII. Our prior blog post covers this specific situation in more detail.
Email Compromise Events Will Rise Along with Wire Fraud
Incidents involving threat actors gaining access to organizational email accounts will continue to rise in 2021. This increase can be attributed to password re-use, credential harvesting attacks, data leaks following a breach or extortion event, malware, phishing, smishing, etc. Motivation for these attacks typically involve obtaining information that can be used to facilitate other types of attack. Threat actors steal signature lines, email recipient metadata, prior dealing information, and payment information. This allows a threat actor to set up convincing-looking emails/invoices to perpetrate bank fraud. This comes in the form of requesting a fake invoice be paid or bank information changed. Unfortunately, this person-in-the-middle type attack often goes undetected by the legitimate employees involved. In 2021, organizations should focus on employee training to increase awareness, sophistication, and “cyber-suspicion” of their employees. Organizations will benefit from taking a closer look at their email system logging to ensure that requisite logs are available to conduct investigations following a business email compromise.
