Week in Breach 11/2/22-11/8/22

Risk to Business: 2.836 = Moderate

Dropbox has revealed that they have experienced a data breach. The company noted unauthorized access to some of its repositories after a successful phishing attack. That attack resulted in someone copying 130 of its private GitHub code repositories and swiping some of its secret API credentials. Microsoft’s GitHub detected suspicious behavior on Dropbox’s corporate account on October 13 and informed the company. Dropbox ultimately determined the cause was a phishing attack in which bad actors impersonated the code integration and delivery platform CircleCI. Reports point out that three weeks before the attack, GitHub warned of phishing campaigns that involved the impersonation of CircleCI. Dropbox also said the intruder’s access to the GitHub repo silo was revoked on October 14, and that all developer API credentials to which the intruder had access have been rotated.

The LockBit 3.0 ransomware group has added Kearney & Company, an accounting and financial services firm that does business with the U.S. government, to its published list of victims on November 05. That group is threatening to publish the firm’s stolen data by November 26, 2022, if the company doesn’t pay the $2 million demanded ransom. A sample of the stolen data including financial documents, contracts, audit reports and billing documents has been published on the group’s dark website.

Label printing company Multi-Color Corporation (MCC) has disclosed that on September 29, 2022, it discovered unauthorized access to its network. An investigation revealed that sensitive HR data might have been compromised, including personnel files and information on employees’ enrollment in benefits programs. Both current and former MCC employees are impacted. Some reports are saying that this was a ransomware attack. 

Individual Risk: 2.815 = Moderate

The company’s breach announcement said that sensitive personal data of MCC employees and their spouses, partners, and/or dependents who are enrolled in the benefits programs may have been exposed. Exposed data may include a person’s name, date of birth, email address, mailing address, telephone number, Social Security number, driver’s license number, healthcare and health insurance-related data, and certain tax and financial data. 

Risk to Business: 1.382 = Extreme

Somnia Inc, a physician-owned firm that manages anesthesiology practices, has experienced a data breach that may impact an estimated 20 practices serving about 430,000 people. A company spokesperson confirmed that the firm is the management services organization behind the recent breaches affecting many anesthesiology practices. Somnia declined to disclose how many clients and individuals in total were affected. The company said that their forensic investigation into a security incident found that some information stored on the management company’s systems may have been compromised. 

Individual Risk: 1.361 = Extreme

Affected information includes individuals’ name, Social Security number, and some combination of data including date of birth, driver’s license number, financial account information, health insurance policy number, medical record number, Medicaid or Medicare ID and health information such as treatment and diagnosis.

Risk to Business: 1.619 = Severe

Vodafone Italia is sending customers notices of a data breach after one of its partners, FourB S.p.A., a reseller of telecommunications services, suffered a cyberattack. The incident took place in the first week of September and likely resulted in the compromise of sensitive subscriber details. A cybercrime group, KelvinSecurity, claimed that they’d successfully attacked Vodafone in early September, but the company denied an intrusion at that time. KelvinSecurity put a collection of 295,000 files totaling 310 GB of data up for sale. There has not been confirmation that the two incidents are connected but it seems highly likely.

Risk to Business: 1.684 = Severe

Danish train operator DSB experienced a service outage that shut down all of its trains on Saturday morning after a ransomware attack at one of its service providers. That service provider, software firm Supeo, was forced to shut down its servers after a suspected ransomware attack, resulting in the loss of access to a critical piece of software used by train drivers and halting trains around the country. Supeo provides a mobile application that train drivers use to access critical operational information including speed limits and information on work being done to the railroad. DSB, the largest railway operator in Denmark, was able to resume service later on Saturday after significant delays. 

Risk to Business: 2.283 = Severe

Customers of the Melbourne City branch of real estate company Harcourts were informed that the company was hit by a cyberattack last month that may have exposed the personal information of tenants, landlords and service providers. The company disclosed that an unknown party had accessed its rental property database on October 24 after an incident at one of its service providers, Stafflink, a company that provides franchisee administrative support. The account of a Stafflink employee was allegedly compromised and accessed by an unknown third party, giving bad actors access to the data. Interestingly, Stafflink said in a statement “We understand the unauthorised access occurred because the representative of Stafflink was using their own device for work purposes rather than a company-issued (and more secure) device.” 

Risk to Business: 1.936 = Severe

PNORS Technology Group, an IT services provider for six departments of the Australian government, announced that two of its units, Datatime Services and Netway Networks, were hit in a cyber attack on November 3. The company confirmed that it had experienced encryption and data theft, as well as the fact that an unnamed cybercrime group has provided a sample of the stolen data as proof of the attack. No information was available at press time on ransom demands or timelines. Data snatched in this incident may include sensitive information about families in the Victorian school system collected as part of school entrance records. The company says that it has informed impacted entities as well as the Office of the Australian Information Commissioner, and an investigation is ongoing.
