In an unexpected twist, AT&T found itself embroiled in a cybersecurity scandal that could have exposed a vast trove of sensitive information from its wireless customers. A hacker, who claimed to have accessed call and text logs, allegedly received around $400,000 in Bitcoin to erase the data. This relatively modest payment, verified by blockchain analysis, contrasts sharply with other hefty ransom deals seen in recent high-profile breaches.
While AT&T and federal agencies remained tight-lipped, the shadowy nature of the transaction points to a deeper issue of data security and the length companies might go to protect their customers' privacy.
A hacker recently claimed to have stolen sensitive call and text logs from AT&T Inc. According to the hacker, AT&T paid approximately $400,000 to have this data erased. This revelation surfaced when an analysis of a Bitcoin wallet address provided by the hacker showed a transaction aligning with an extortion payment.
An unnamed person familiar with the ransomware negotiations confirmed the payment from AT&T. The hacker had supposedly stolen a huge cache of call and text logs, along with some location information. Despite these claims, AT&T has declined to comment, and it remains unclear if an intermediary was used to pay the hacker.
The scope of the stolen data included call and text logs from nearly all of AT&T's wireless customers over a six-month period in 2022. The sensitive nature of this data presented substantial national security risks. Some experts noted that the ransom payment amount seemed remarkably low compared to other recent high-profile extortion events.
According to the hacker, this incident wasn't a solo operation. Other hackers were also involved in the attack. To substantiate their compliance, the hacker provided a seven-minute video allegedly showing the deletion of the stolen data. However, Bloomberg was unable to verify the authenticity of the video and the hacker’s claims of involvement from other attackers.
Despite multiple inquiries, AT&T has chosen not to comment on whether they received the video. They did, however, express confidence that the stolen call and text logs had not been made public. AT&T was actively collaborating with federal law enforcement to handle the security incident and mitigate any fallout.
At Bloomberg's request, Chainalysis Inc. examined the payment record provided by the hacker and compared it to information on the blockchain. Their analysis supported the likelihood that the payment was indeed an extortion. The transaction history showed a smaller sum being moved to another wallet known to be associated with a hacker, although Chainalysis couldn't definitively say if AT&T made the initial payment.
While $400,000 might seem like a significant amount, it's relatively low compared to ransom demands in other cyber incidents. For example, Colonial Pipeline Co. paid $4.4 million after a ransomware attack in 2021, and UnitedHealth Group Inc. made a $22 million payment following a breach.
Jon DiMaggio, Chief Security Strategist at Analyst1, pointed out that $400,000 is a minor expense for a company like AT&T. He suggested that the relatively low ransom payment might result from the hacker accessing no financial records or highly valuable information.
The hacker claimed they did not believe the stolen information was particularly valuable or knew who would be interested in purchasing it. This possibly explains the comparatively low ransom demand.

| Incident Involved | Ransom Paid | Context |
|---|---|---|
| Colonial Pipeline Co. | $4.4 million | Ransomware attack interfering with gas supplies on the US East Coast |
| UnitedHealth Group Inc. | $22 million | Payment to cybercrime group after a breach in its subsidiary |
| AT&T Incident | $400,000 | Alleged payment to erase sensitive call and text logs |
The breach was linked to a security incident at Snowflake Inc., a data analysis software provider. This incident was part of a larger campaign affecting up to 165 Snowflake customers. Snowflake continues to grapple with the reputational impact of the hack.
AT&T's response involved working closely with federal law enforcement officials and delaying public disclosure of the incident twice, in May and June 2024, due to national security and public safety concerns.
This incident underscores the critical importance of robust data security measures, especially for corporations that handle vast amounts of sensitive information. Companies must continually assess and fortify their security protocols to prevent similar breaches.
Knowing how to effectively handle ransom demands and ransomware negotiations is crucial. Engaging experts and federal authorities can help manage and mitigate such crises more efficiently.
The role of transparency and timely communication in managing breaches cannot be overstated. Keeping the public and customers informed while balancing national security concerns can help maintain trust and reputation.
The alleged payment by AT&T highlights the ongoing battle between large corporations and increasingly sophisticated hackers. While this specific ransom was relatively low, it serves as a stark reminder of the vulnerabilities that even the largest companies face. Maintaining rigorous security, preparing for potential breaches, and managing ransom negotiations are vital to safeguarding sensitive information and protecting a company’s reputation.
Stay vigilant, keep your security updates current, and always have a response plan in place. You never know when you might need it.
