Pointing in All Directions  

Welcome to the Identity Theft Resource Center’s (ITRC) Weekly Breach Breakdown for April 9, 2021. Each week, we look at the most recent and interesting events and trends related to data security and privacy. President Harry Truman once said that if you put all the government experts in a straight line, they’d point in all directions. That might be a good title for this week’s episode where we look at the data compromise and cybersecurity trends for the first quarter of the year in the ITRC’s Q1 2021 Data Breach Report. There’s a little something for everyone in these numbers. 

Data Compromises Rise 12 Percent 

According to the ITRC’s Q1 2021 Data Breach Report, the number of publicly-reported U.S. data breaches and exposures are up 12 percent from Q4 2020 to 363 total compromises. That’s a slight reversal of the trend in 2020. However, part of the reason for the increase was 59 compromises that occurred late in Q4 2020 but were recorded in Q1 2021. With that said, the number of breaches would have been down nearly a quarter in the first three months of this year compared to the final three months of last year. 

Number of Individuals Impacted Rise 564 Percent 

The number of individuals impacted, though, is up significantly. Fifty-one (51) million people had their data compromised in Q1 2021 versus eight million in Q4 2020. That’s a 564 percent increase. If people set aside the late notices from 2020, the primary reason for the gap between compromises versus people impacted is a 42 percent rise in the number of supply chain attacks compared to Q4 2020.  

Supply Chain Attacks to Blame for Increasing Numbers 

We’ve talked about this kind of attack before. Supply chain attacks happen when cybercriminals attack a vendor to access the systems or data of the company’s customers. Think Blackbaud in 2020 or Accellion this year. Supply chain attacks at 27 third-party vendors impacted 137 U.S. organizations and seven million individuals this quarter. There were 19 supply chain attacks in Q4 2020. 

Top Root Causes for Q1 2021 Data Compromises  

By the way, phishing and ransomware attacks remained the number one and two root causes of data compromises in Q1, according to the Q1 2021 Data Breach Report. Malware was a distant third, but supply chain attacks were only slightly behind. At the current growth rate, supply chain attacks could pass malware in Q2 2021. 

Blackbaud Continues to Result in New Data Breach Notices 

The double-digit jump in supply chain attacks in Q1 2021 does not include the continual impact of third-party exploits first reported in 2020. The mid-year 2020 attack against IT provider Blackbaud continues to result in new data breach notices: 62 in Q1 2021 that impacted an estimated 146,000 individuals. To date, nearly 13 million people and 555 organizations have been affected by this single event. 

SolarWinds Supply Chain Attack 

Q4 2020 ended with a blockbuster revelation of a supply chain attack against key cybersecurity and software companies – namely SolarWinds – that was the tip of a much bigger iceberg. In Q1 2021, major supply chain attacks against MicrosoftAccellion and other service organizations were announced. The attacks put the personal information of millions of individuals and corporate IPs at risk.  

Cybercriminals Continue to Focus on Credential Theft  

Here’s the bottom line from the Q1 2021 Data Breach Report: The Q1 trends continue to point to a rise in cybercrimes focused on stealing company resources using personal information. The broader trend of cybercriminals preferring to exploit multiple organizations through a single point-of-attack may also be accelerating.  

That may sound like good news for individuals. However, what it means is that businesses and individuals alike need to adapt to the new ways cybercriminals are behaving.
