How To Stay Safe From Hackers Who Access Google Accounts Without Using Passwords

A startling revelation from security researchers uncovers a concerning vulnerability within Google’s system, shaking the foundation of online security. This exploit, revealed by CloudSEK, involves a clever manipulation of third-party cookies, allowing hackers to access Google accounts without needing the user’s password. This threat, already being actively tested by malicious hacking groups, poses a substantial risk to user privacy and data security.

Pavan Karthick M, a threat intelligence researcher at CloudSEK, shed light on the intricacy of this cyber threat, emphasising its stealthy nature. “This exploit enables continuous access to Google services, even after a user’s password is reset,” Pavan Karthick stated, emphasising the urgency for vigilant monitoring of emerging cyber threats.


Exploiting Cookies: The Unseen Threat


At the core of this security breach lies the exploitation of Google authentication cookies, a fundamental aspect of seamless user experience. These cookies, designed to facilitate easy access to accounts without constant login demands, have inadvertently become a gateway for malicious access. By manipulating these cookies, hackers circumvent two-factor authentication, posing a serious challenge to conventional security measures.

CloudSEK’s analysis pinpointed a zero-day exploit that grants hackers “session persistence,” allowing them to retain access despite password changes. The exploit’s sophistication grants threat actors an alarming level of control, making it imperative for users to take immediate action.


Ongoing Risks: Hackers’ Advancements


Despite the exploit being brought to public attention, hackers have swiftly integrated it into their malware, amplifying the danger. Threat groups like Rhadamanthys, Risepro, Meduza, and Stealc Stealer have reportedly adopted this technique, escalating the risk landscape for Google account holders.

Google’s response has been to fortify their defenses and recommend user actions to mitigate risks. However, the urgency of the situation necessitates comprehensive solutions to counteract this evolving threat. CloudSEK’s findings highlight an urgent need for proactive measures beyond traditional security protocols to safeguard user data.

This situation paints a picture of a relentless cyber battleground, urging both users and tech giants like Google to fortify defenses and develop innovative security measures to protect against increasingly sophisticated cyber threats.


Recognising and Responding to Account Compromise


Identify Suspicious Activity


If you suspect unauthorised access or odd behavior within your Google Account, swift action is crucial. Signs of compromise may include unfamiliar device logins, changes in critical security settings like recovery information or account names, or even unexpected financial transactions. Google recommends regular checks for any unusual activity across its suite of services, from Gmail to Google Drive and beyond.

According to Google Support, notifying users through notifications about unusual sign-ins, security setting alterations, or suspicious activities is a primary way the system alerts account holders. A vigilant eye on these notifications is essential in identifying potential threats.


Steps to Recovery


Google offers a detailed step-by-step process for account recovery. If you’ve experienced suspicious behaviour or feel your account’s security is compromised, it’s advised to immediately access the account recovery page. This involves answering specific security questions or providing necessary details to confirm ownership and regain control of the account.

On top of this, users are encouraged to reset passwords promptly if they suspect account intrusion. Creating robust, unique passwords significantly enhances account security, reducing the likelihood of unauthorised access.


Implement Additional Security Measures


Enabling 2-Step Verification is a powerful shield against unauthorised access. This additional layer of security requires a secondary confirmation step, ensuring the rightful account holder’s access. Google advocates for its use across all online accounts, emphasising its effectiveness in thwarting cyberattacks.

Another aspect involves reviewing and securing associated devices and apps. Regularly checking and managing which devices have access to your Google Account, removing any unnecessary permissions, and updating security settings on apps can significantly bolster account protection.


Keeping Your Personal Data Safe


Beyond device and app management, Google suggests being cautious with personal data stored within your account. If financial information or sensitive documents are linked, regularly reviewing and removing any unauthorised access becomes a necessity. Additionally, ensuring secure browsing habits, installing reliable antivirus software, and using trusted browsers like Google Chrome can add layers of defense.
