Charter Communications data breach affects 4.9 million accounts

The ShinyHunters extortion gang stole personal information from 4.9 million accounts after hacking the U.S. telecom giant Charter Communications in early April, according to data breach notification service Have I Been Pwned.
Charter has over 92,000 employees and provides internet, mobile, video, and voice services to more than 32 million customers and over 57 million homes in 41 states across the U.S. through its Spectrum brand.
The company confirmed the breach earlier this week, saying that the attackers did not steal sensitive personal customer information and that it had alerted authorities about the incident.
"No sensitive personal information (PI) or customer proprietary network information (CPNI) data was exfiltrated by the threat actor as a result of recent activity," Charter told BleepingComputer.
While Charter has yet to attribute the attack and has not shared further details, the ShinyHunters extortion gang claimed responsibility and told BleepingComputer that they breached the company's systems on April 1 in a voice phishing (vishing) attack that compromised an employee's Microsoft Entra account.
The threat actors claimed they used this access to steal 42 million records from the company's Salesforce instance, including consumer and business customer names, email addresses, physical addresses, phone numbers, phone types, plan information, support ticket data, and some CPNI data.
After the company refused to pay the ransom demanded by ShinyHunters to have the stolen data returned and destroyed, the cybercrime group leaked the documents stolen from Charter's Salesforce instance on their dark web leak site.
BleepingComputer reached out to Charter again about the extortion gang's claims that they also stole additional CPNI data but was referred back to the company's original statement.

Although Charter declined to share further details, including whether threat actors also exfiltrated CPNI data from its systems, Have I Been Pwned analyzed the leaked data and confirmed that the incident affected 4.9 million accounts, whose names, email addresses, job titles, phone numbers, and physical addresses were stolen.
"The group later published the data, which exposed 4.9M unique email addresses along with names, phone numbers and physical addresses," Have I Been Pwned said. "A subset of approximately 85k records originating from an internal employee directory also included job titles."
ShinyHunters has been targeting Salesforce customers over the past year, breaching hundreds of companies worldwide and claiming the theft of billions of records in Salesforce Aura data theft attacks and a Salesloft Drift campaign.
The FBI has recently advised ShinyHunters' victims not to give in to the gang's ransom demands, after previously warning that doing so cannot guarantee that threat actors won't attempt to sell the stolen data to other cybercriminals or extort them again.
Charter Communications' systems were also compromised in a wave of breaches by a Chinese state-backed threat group tracked as Salt Typhoon that also impacted AT&T, Verizon, Consolidated Communications, Windstream, and Lumen, as well as telecom companies in dozens of other countries.

The data breach suffered by Charter Communications involved extortion by the ShinyHunters group, who reportedly stole personal information from 4.9 million accounts following a hack in early April. While Charter Communications initially stated that no sensitive personal information or customer proprietary network information was exfiltrated during the recent activity, the threat actors claimed responsibility for the breach, citing a voice phishing attack that compromised an employee's Microsoft Entra account as the entry point. Subsequently, the threat actors claimed to have stolen 42 million records from the company's Salesforce instance, which included consumer and business customer names, email addresses, physical addresses, phone numbers, phone types, plan information, support ticket data, and some customer proprietary network information.

When Charter refused the ransom demanded by ShinyHunters to have the stolen data returned and destroyed, the cybercrime group proceeded to leak the documents from the Salesforce instance onto their dark web. Analysis by Have I Been Pwned confirmed that the incident affected 4.9 million unique accounts, exposing names, email addresses, phone numbers, and physical addresses. Furthermore, a subset of approximately 85,000 records originating from an internal employee directory also included job titles. This incident occurred against the backdrop of broader cybersecurity threats; Charter Communications’ systems were also affected by a wave of breaches involving the Chinese state-backed threat group Salt Typhoon, which impacted other major telecommunications entities including AT&T, Verizon, Consolidated Communications, Windstream, and Lumen, as well as telecom companies across numerous other countries.

The FBI has advised the victims of the extortion gang not to comply with the ransom demands, warning that payment does not guarantee the threat actors will refrain from further extortion or the sale of the stolen data to other cybercriminals. This event highlights the complexities of data security within large telecommunications organizations and the aggressive tactics employed by sophisticated threat actors targeting enterprise systems and customer data repositories. The incident underscores the necessity for organizations to validate security controls beyond basic network penetration testing to effectively mitigate modern cyber risks.
