Kroll experts have noticed an increase in distributed denial of service (DDoS) attacks by cybercriminals seeking to turn a profit in two distinct incident types. First, many ransomware operators are now threatening and conducting DDoS attacks as an additional pressure tactic during the ransom negotiation process. Second, also known as ransom denial of service (RDoS), attackers threaten DDoS attacks that will take down an organization’s public-facing services unless a ransom is paid.
On the afternoon of July 2, 2021, Kaseya reported that it had been impacted by a ransomware attack affecting its Virtual System Administrator (VSA) product and advised users to shut down VSA servers immediately. Initial reporting indicates this was a well-orchestrated supply chain attack impacting about 60 managed services providers (MSPs) and up to 1,500 client organizations by leveraging a zero-day vulnerability (CVE-2021-30116).
The recent slate of breaches and regulatory actions has prompted many companies who had been doing the minimum in terms of proactive cyber risk management to rethink their approach. In the U.S., new regulations are emerging (for states like Virginia, Colorado, Massachusetts and many others), and existing regulators are increasing their enforcement, as we’ve seen by the NY Dept of Financial Services (NYDFS) and the SEC.
Phishing schemes are always evolving. This past year, email thread hijacking took phishing to new depths of subterfuge as criminals hid in plain sight within existing conversations. But no matter how well cybercriminals have refined their messaging or counterfeited legitimate logos and branding, the one constant has always been their delivery method: email. Until now. Online chat services have become a new target for cybercriminals to introduce documents loaded with malware into organizations.
Industries most impacted in 2019 continued to be hard hit in both 2020 and so far in 2021, including healthcare, education and financial services. However, the greatest percentage increases occurred in industries that had been generally spared in 2019. The overall implication is that data attacks became broader and deeper during the pandemic, a trend that continues during the recovery.
