Weak Cloud Credentials Behind Most Cyber Attacks: Google Cloud Report

 



A recent Google Cloud report has found a very troubling trend: nearly half of all cloud-related attacks in late 2024 were caused by weak or missing account credentials. This is seriously endangering businesses and giving attackers easy access to sensitive systems.


What the Report Found

The Threat Horizons Report, which was produced by Google's security experts, looked into cyberattacks on cloud accounts. The study found that the primary method of access was poor credential management, such as weak passwords or lack of multi-factor authentication (MFA). These weak spots comprised nearly 50% of all incidents Google Cloud analyzed.

Another factor was screwed up cloud services, which constituted more than a third of all attacks. The report further noted a frightening trend of attacks on the application programming interfaces (APIs) and even user interfaces, which were around 20% of the incidents. There is a need to point out several areas where cloud security seems to be left wanting.


How Weak Credentials Cause Big Problems

Weak credentials do not just unlock the doors for the attackers; it lets them bring widespread destruction. For instance, in April 2024, over 160 Snowflake accounts were breached due to the poor practices regarding passwords. Some of the high-profile companies impacted included AT&T, Advance Auto Parts, and Pure Storage and involved some massive data leakages.

Attackers are also finding accounts with lots of permissions — overprivileged service accounts. These simply make it even easier for hackers to step further into a network, bringing harm to often multiple systems within an organization's network. Google concluded that more than 60 percent of all later attacker actions, once inside, involve attempts to step laterally within systems.

The report warns that a single stolen password can trigger a chain reaction. Hackers can use it to take control of apps, access critical data, and even bypass security systems like MFA. This allows them to establish trust and carry out more sophisticated attacks, such as tricking employees with fake messages.


How Businesses Can Stay Safe

To prevent such attacks, organizations should focus on proper security practices. Google Cloud suggests using multi-factor authentication, limiting excessive permissions, and fixing misconfigurations in cloud systems. These steps will limit the damage caused by stolen credentials and prevent attackers from digging deeper.

This report is a reminder that weak passwords and poor security habits are not just small mistakes; they can lead to serious consequences for businesses everywhere.

Cybercriminals Exploit Cloud Services to Steal Login Information

 


You may think you are receiving an email from your trusted ProtonMail account — only to discover it’s a trap set by cybercriminals. Recent research throws light on how attackers are targeting both widely known and lesser-used cloud platforms like AT&T, Comcast Xfinity, and Gravatar to deceive users into handing over their credentials.  

This growing trend is a testament to how cybercriminals evolve to exploit users’ trust in familiar brands and unsuspecting services, creating significant security risks for individuals and businesses alike.  


What Are Cloud Services, and Why Are They Targeted?

To understand these threats, it’s crucial to know what cloud services are. These platforms allow users to access tools and store data online, eliminating the need for physical hardware. Examples include ProtonMail, which provides secure email communication, and Gravatar, a service that manages user avatars across the web.  

Cybercriminals target these services due to their widespread adoption and the trust users place in them. Services like Gravatar, often overlooked in cybersecurity protocols, become particularly attractive to attackers as they can bypass many conventional defenses.  


How Attackers Exploit Cloud Platforms 

While telecom giants like AT&T and Comcast Xfinity are attacked for their reputation and vast user base, platforms like Gravatar are exploited due to their unique features. For instance, Gravatar’s “Profiles as a Service” functionality allows attackers to create convincing fake profiles, tricking users into revealing sensitive information.  

The methods attackers use often depend on two key factors:  

1. Familiarity: Trusted brands like AT&T and Comcast Xfinity are lucrative targets because users inherently trust their platforms.  

2. Low Visibility: Lesser-known platforms, such as Gravatar, often evade suspicion and security monitoring, making them easy prey.  


How Credential Theft Works  

Cybercriminals follow a systematic approach to harvest user credentials:  

1. Deceptive Emails: Victims receive phishing emails that mimic trusted platforms.  

2. Fake Websites: These emails direct users to fraudulent login pages resembling legitimate ones.  

3. Impersonation: Fake profiles and interfaces add credibility to the scam.  

4. Data Theft: Once users input their login details, attackers gain unauthorized access, leading to potential breaches.  


Telecom Companies Under Siege  

Telecommunications companies like AT&T, Comcast Xfinity, and regional Canadian ISPs, including Kojeko and Eastlink, are particularly vulnerable. These companies manage vast amounts of sensitive user data, making them high-value targets. A successful breach could enable hackers to exploit customer data on a massive scale, creating widespread consequences.  


How to Protect Yourself from These Attacks  

To stay secure against credential theft attempts, follow these precautions:  

  1. Verify Websites: Always confirm the authenticity of a URL before entering personal information.  
  2. Scrutinize Emails: Be cautious of unsolicited emails, especially those requesting sensitive data.  
  3. Strengthen Passwords: Use complex, unique passwords for every account.  
  4. Two-Factor Authentication (2FA): This adds an extra security layer, making it harder for attackers to succeed.  
  5. Stay Updated: Regularly educate yourself on emerging cybersecurity threats.  


Conclusion: Awareness is Key to Cybersecurity

Credential theft campaigns have become more intricate in their execution, targeting both renowned and overlooked platforms. By understanding the tactics used by attackers and adopting proactive security measures, individuals and businesses can safeguard themselves from these evolving threats.

AT&T Confirms Cyberattack Amid Salt Typhoon Hacking Incident

 

AT&T has confirmed being targeted in the Salt Typhoon hacking attack, a cyber operation suspected to involve China. Despite the attack, the telecommunications giant assured customers that its networks remain secure.

In a statement, AT&T revealed that hackers aimed to access information related to foreign intelligence subjects. The company clarified, “We detect no activity by nation-state actors in our networks at this time.” It further added that only a limited number of individuals’ data had been compromised. Affected individuals were promptly notified, and AT&T cooperated with law enforcement to address the breach.

Investigation and Preventive Measures

To prevent future incidents, AT&T is collaborating with government agencies, other telecom companies, and cybersecurity experts. The company has intensified its monitoring efforts and implemented enhanced measures to safeguard customer data.

The Salt Typhoon attack is not an isolated event; it forms part of a broader wave of cyberattacks targeting major telecom companies. Reports suggest that hackers may have accessed systems used by federal agencies to process lawful wiretapping requests. These systems play a critical role in law enforcement operations, making their compromise particularly alarming.

In October, similar breaches were reported by other telecom providers. Verizon Communications disclosed suspicious activity, and T-Mobile revealed it had thwarted an attempted breach before customer data could be accessed.

White House Deputy National Security Advisor Anne Neuberger stated that nine telecom companies had been targeted in the Salt Typhoon attack but refrained from naming all the affected firms.

China, in response, denied any involvement in the attacks, asserting that it opposes state-sponsored cyber activities.

Lessons for Cybersecurity

The Salt Typhoon attack underscores the critical need for robust cybersecurity practices in the telecom industry. AT&T’s prompt response highlights the importance of transparency and collaboration in addressing cyber threats.

Salt Typhoon Hack: A Grave Threat to U.S. Telecommunications

 


The Chinese state-sponsored hacking group Salt Typhoon has been implicated in one of the most severe breaches in U.S. telecommunications history. Sensitive information, including call logs, timestamps, phone numbers, and location data, was compromised across the networks of at least eight major telecom carriers, including AT&T and Verizon. Despite the scale of the intrusion, many affected consumers remain uninformed about the breach.

Scope and Impact of the Breach

According to reports, Salt Typhoon’s hacking campaign has targeted high-value intelligence figures, including presidential candidates Donald Trump and Kamala Harris, as well as Senator Chuck Schumer's office. The FBI estimates that millions of users’ metadata, particularly in the Washington, D.C., area, were accessed. Yet, most affected individuals have not been notified, raising serious privacy concerns.

AT&T and Verizon, the most severely impacted companies, have faced backlash for their limited response to the breach. Privacy groups have criticized the telecom giants for failing to comply with the Federal Communications Commission (FCC) mandate requiring companies to inform customers of breaches that could cause significant harm, such as identity theft or financial loss.

Telecom Industry’s Response

While high-value targets were promptly alerted, the majority of users whose data was compromised were not informed. In an interview with NBC, Alan Butler, executive director of the Electronic Privacy Information Center, condemned the carriers’ "deficient practices." He emphasized the need for transparency, urging companies to notify all affected customers, regardless of whether their metadata or the actual content of their communications was accessed.

Charter Communications, a midsize internet service provider, has taken a relatively open approach, acknowledging infiltration by Salt Typhoon. According to Chief Security Officer Jeff Simon, access by the hackers has since been cut off, and no customer information was reportedly accessed. In contrast, other companies like Lumen, another internet service provider, have downplayed or refused to disclose the extent of the breach.

Ongoing Threats and Legislative Action

Cybersecurity experts warn that Salt Typhoon continues to target U.S. telecom networks and IT infrastructure. Government agencies are closely monitoring the situation to mitigate further risks. Lawmakers are now considering stricter cybersecurity regulations to compel telecom companies to adopt robust practices and provide detailed breach notifications to consumers.

However, some companies targeted by Salt Typhoon claim the hackers did not gain substantial information. For example, Lumen stated that federal partners found no evidence of ongoing activity in its networks.

Consumer Awareness and Future Outlook

While telecom companies have yet to adequately address these breaches, consumers must stay informed about security risks by following news updates on data breaches. Public pressure is likely to drive industry-wide changes, prompting carriers like AT&T and Verizon to adopt comprehensive notification systems for all affected users.

The Salt Typhoon breach serves as a wake-up call for the telecommunications industry to prioritize data security. Enhanced transparency, stricter cybersecurity regulations, and informed decision-making will be crucial to safeguarding sensitive information in an increasingly digital world.

AT&T Claims It Has Fixed Software Bug That Caused An Outage For Some Wireless Users

 

Some AT&T customers experienced a disruption in their wireless service earlier this week, which made it difficult for them to call 911 in an emergency. 

It was rectified in a few hours, with the company blaming a software fault, but it's only one of many issues the wireless provider has experienced in recent months, including outages and data breaches that have disrupted operations and left users in the dark.

Earlier this year in February, its network went down for 11 hours, preventing several of its clients in the United States from making calls, texting, or using the internet. AT&T stated that an initial investigation of the outage revealed that it might have been caused by an internal error rather than a cyberattack. 

A few weeks later, in March, a data dump containing private information for 73 million current and past customers was exposed onto the "dark web," raising security concerns. According to the company, the data was from 2019 or earlier and did not appear to include financial information or call history specifics. 

"It is unclear whether the data originated from AT&T or one of its vendors," the company stated at the time. Then, in June, another AT&T outage prevented some consumers from making phone calls between carriers. The issue was resolved within a few hours, but the firm did not disclose what triggered it.

Notably, this week's outage occurred just hours after the Federal Communications Commission announced a $950,000 settlement with AT&T to resolve an investigation into whether the company violated FCC rules by failing to deliver 911 calls and promptly notifying 911 call centres during a previous outage in August 2023. 

AT&T’s overflow 

Why does this keep occurring to AT&T? CNN spoke with a telecommunications expert who believes there are three main factors at play: software updates gone awry, numerous technological challenges, and congested networks in big cities. 

An outage map from Tuesday shows interruptions in New York, Charlotte, North Carolina, Houston, and Chicago. Alex Besen, founder and CEO of Besen Group, which analyses mobile phone carriers, believes it was a network overload issue. 

“To avoid any future outages, AT&T needs to increase the number of cell towers, implement advanced load-balancing techniques, use network optimization tools to manage traffic more effectively and prioritize services that can reduce congestion,” Besen stated.

AT&T Data Breach: Essential Steps for Victims to Protect Themselves

 

Telecom giant AT&T recently disclosed a massive data breach affecting nearly all of its approximately 110 million customers. If you were a customer between May 2022 and January 2023, there is a high chance your data, including call and text message records, was accessed through an illegal download from a third-party cloud platform. Customers should watch for contact from AT&T or check their accounts for notifications. First, change your password. 

Since your password is likely compromised, update it on both your AT&T account and any other accounts where it was used. While it’s inconvenient, using different passwords for each service is essential. Numerous tools can create secure, randomly generated passwords, and password managers can help you remember them. Also, activate two-factor authentication on your account and any other accounts using the same password. Combining two login methods enhances security. Given the nature of this leak, consider changing your cell phone number as well. Prepare for an increase in spam calls, but the bigger concern is potential scammers.

Be extra cautious about giving out personal details such as banking information or your address over the phone, as these could be cleverly disguised phishing schemes. Stay vigilant online, as even anonymous phone number information can be pieced together by scammers to identify individuals. Treat every email from unfamiliar addresses as suspicious. Additionally, inform your bank about the breach. They can monitor for any suspicious transactions and introduce new security measures to ensure you are contacting your bank, not an imposter.  

Lastly, protect yourself further by using one of the best VPNs to secure your online data. VPNs not only spoof your IP address location but also securely encrypt your data. There are even free VPN plans like ProtonVPN. Many VPNs also include antivirus elements. For instance, NordVPN has its Threat Protection Pro system, which is effective against phishing. A Surfshark One subscription includes dedicated antivirus software and an Alternative ID feature, which allows you to sign up for services online with randomly generated details, including a decoy phone number. With an Alternative ID, you can create accounts for less trustworthy services (or those frequently attacked, like AT&T) with peace of mind. 

This way, you can minimize spam and rest assured that if your details get leaked, you haven’t actually been compromised. Hackers will have nothing to piece together; you can simply disconnect that ID, generate another random identity, and move on securely.
