Zendesk data breach overview: 

  • Who: Zendesk has informed crypto trading and portfolio management company Coinigy of a data breach that may have exposed some service data belonging to Coinigy’s account.
  • Why: Zendesk said the data breach was the result of a “sophisticated SMS phishing campaign” that successfully targeted some of its employees. 
  • Where: Nationwide

Software company Zendesk has informed the crypto trading and portfolio management company Coinigy that it suffered a data breach following a “sophisticated SMS phishing campaign” that targeted several of its employees. 

Coinigy has revealed Zendesk said it became aware of the data breach in October, discovering at that time that some of its targeted employees handed over their login details to the bad actors, SecurityWeek reported

Zendesk reportedly disclosed to Coinigy that the hackers — from between the time period of Sept. 25 and Oct. 26, 2022 — were able to access data that was unstructured and in a logging platform. 

Coinigy was informed service data belonging to the company’s account was potentially included in the compromised logging platform data, per a discovery during an ongoing review into the incident that Zendesk said it is conducting, SecurityWeek reported. 

Zendesk says no indication Coinigy’s Zendesk instance exposed during data breach

Zendesk reportedly said, however, that it had discovered no indication that Coinigy’s Zendesk instance had been exposed during the data breach, but that it was continuing to look into the possibility. 

Other companies affected by the purported data breach against Zendesk appear to have been informed by the software company sooner than Coinigy, which only received notice this month, according to SecurityWeek. 

Cryptocurrency exchange Kraken, for example, reportedly informed its customers in November about a data breach against Zendesk, with the platform saying at the time that customer accounts and funds were not at risk. 

In another data breach reported this month, PayPal revealed that a credential stuffing attack led to a data breach that exposed the personal information of almost 35,000 of the e-commerce company’s users.
