How can you detect if your online accounts have been compromised?

You can detect if your online accounts have been compromised by monitoring for signs such as unauthorized activity, unexpected changes to account settings, receiving suspicious emails or notifications claiming account access, noticing unfamiliar devices logged into your accounts, and regularly reviewing login history and security alerts provided by the online service or platform.

A good way to detect some account exposure is holding a good Threat Intelligence Service contracted doing a real time research into Dark Web to reducing the Risk, and giving you time to response, but over than this, keep a MFA Service embales into all your possible Account and try to out base some ITDR monitoring your global catálog could reinforce your strategy giving more performance to your CSIRT Team.

Some unusual activities are login from unusual locations or times. User Behavior Analytics (UBA) help a lot here. Thankfully account providers are aware of this too and usually block logging in, inform you about the activity and require you to prove your identity. However attackers still would have a chance to mimic you. Therefore always use MFA (multifactor authentication)

While monitoring accounts for suspicious activity is important, being proactive with security measures like two-factor authentication, strong unique passwords, and cautious online behavior is crucial to prevent compromise in the first place. Adopting good cybersecurity hygiene makes it much harder for criminals to successfully hack into accounts. Both individuals and businesses must work together on prevention as well as monitoring for maximum protection.

Enabling automatic alerts for suspicious activity is an excellent way to stay informed about potential account compromise. However, these alerts are only helpful if you take prompt action in response. When you receive an unexpected login or password reset notification, immediately change your password and check account settings/activity logs for any unauthorized changes. Two-factor authentication provides critical extra protection by requiring a second step to verify it's really you accessing the account, even if your password is compromised. Enabling 2FA dramatically reduces the risk of account takeover and should be set up everywhere it's offered.

Password alerts notify users of suspicious password activity, such as login attempts from unrecognized devices or locations, multiple failed login attempts, or changes to account passwords without user authorization. These alerts prompt users to review their account security, reset passwords if necessary, and take additional measures such as enabling two-factor authentication to prevent unauthorized access and protect sensitive information from being compromised.

LastPass Security Dashboard: LastPass not only manages your passwords but also offers a security dashboard that provides a security score and dark web monitoring to alert you if your email addresses are found in the data breaches.

Wherever possible, always sign up for MFA. With the help of MFA, there are low chances of your credentials being compromised. A lot more organizations have started providing an option to secure your credentials with MFA and some like banks have made it mandatory. This at first may seem like a tedious process but in case your credentials are being accessed from a location that you usually don't logon from, these organizations send out email alerts and if you are not trying to access your account then you can block access. Push notifications from applications also notify the end user of where their credentials are being accessed from.

In my experience, password alerts can signal someone might be trying to break into your online accounts. These alerts could come in the form of emails about unexpected password resets or login attempts from unrecognized devices or locations. Change your password to a strong, unique one, and consider enabling 2FA if it's offered by the service.

To detect compromised online accounts, look for unusual login activity, suspicious transactions, unverified login attempts, bogus links/calls, notification changes, and unusual login behavior. Use tools like CEAD and check data breach lists to identify potential account compromises.

In my opinion, While getting locked out can be inconvenient, it can also be a wake-up call to improve your account security. By contacting the service provider, updating your security measures, and employing strong passwords, you can turn a potential security breach into a chance to strengthen your online defenses.

Unexpectedly being locked out of your account is a significant red flag, indicating potential unauthorized access. If unable to log in with your credentials, contact the service provider promptly for assistance in recovering your account and investigating the breach. Updating security questions and backup email addresses is advisable to prevent future occurrences. Swift action and enhanced security measures help mitigate risks and safeguard your account from further compromise.

Act swiftly if you find yourself unexpectedly locked out of your account, as it could signal unauthorized access and potential compromise. Contact the service provider immediately to regain access and initiate necessary security measures to safeguard your account and data integrity.

If you are repeatedly locked out of your account or receive notifications of failed login attempts, it may indicate that someone is trying to access your account without permission. This is often one of the most common problems we face when using social media. Check if the service provider offers security features such as temporary account lockout after several failed login attempts as this can help protect your account from brute force attacks.

Regularly check your email inbox for messages from service providers warning about potential security breaches. Companies often send such notices if they suspect a breach or a large-scale attack affecting multiple users. These emails may include instructions on securing your account. However, always verify their authenticity to avoid falling for phishing attempts, fraudulent emails aimed at stealing personal information. By staying vigilant and verifying the legitimacy of such communications, you can better protect yourself from cyber threats.

Existem alguns sites que detém de ferramentas de scan automatizados que checam nas bases vazadas se seus dados ou senhas foram comprometidos em algum momento, como o “Have I Been Pwned”. A própria Apple e Google também detém destas ferramentas e apoiam o cliente com alertas de vazamento ou risco. Para checar se suas senhas pessoais(ex: E-mail) foram vazadas, siga: Dispositivos Apple: Ajustes > Senhas > Recomenda??es de Seguran?a Dispositivos Android: Um alerta será exibido na tela todas as vezes que o usuário fizer login em um aplicativo e o sistema identificar que o código foi exposto na web, orientando a troca imediata do código.

Os acessos s?o temas que vem tomando uma propor??o interessante. Se você obter o log de acesso, será mesmo que é possível dizer se foi correto ou n?o? Vejo duas saídas, a análise comportamental de uma ponta a outra e/ou a utiliza??o de inteligência artificial. Somente assim saímos do tradicional análise de logs e anomalias (que já ocorreram) e passamos a ser mais pró ativos nas detec??es e entendimentos das nossas identidades.

Forwarding Emails: Attackers may set up email forwarding rules to automatically forward incoming emails to an external account they control. This allows them to monitor and collect sensitive information. Changing Account Settings: They might change the account password, recovery email, or other security settings to prevent the legitimate owner from regaining control. Sending Spam or Phishing Emails: Attackers may use the compromised account to send spam or phishing emails to contacts in the address book, spreading malware or attempting to gather more login credentials.

Try not to provide your online account details in any websites. Thats the main and initial thing we have to concentrate on. Some websites will collect this info and sell it to third parties and so on. This will reveal your account identity to other unknown persons, may be the attackers. With few other information like website password, mobile number and dob will help them to guess the password and to try brute force. It’s important to avoid using the same passwords you use for online account for website logins. If security breach happens in the website’s server, our original credentials will be available for the attackers.
