Password Reuse after Dell Hack
US based hardware giants Dell recently announced a security breach that took place earlier in the month of November.
Even though Dell forced its customers to reset their passwords, users should still be concerned. If hackers are able to steal passwords from one website then they can possibly use that information to access some other websites too. It is recommended you reset any passwords for other websites where the same password was used on Dell.com and support.dell.com. Use strong and unique passwords and promote the use of a password manager.

How using Safari can get you Hacked
Dropbox has recently revealed three critical vulnerabilities in the Apple MacOS operating system, which could allow a hacker to execute a malicious code by convincing the victim to visit the malicious web page.
The video demonstration shows that researchers have been able to create a two-stage attack on a Mac computer just by convincing the victim to follow the malicious page. Apple continuously releases updates to fix new vulnerabilities. Users should continuously install monthly updates in order to protect their systems against such threats.

Marriot Data Breach and What Should the Customers do to Protect Themselves
Marriot on Friday reported a data breach affecting the information of 500 million of its Starwood customers. The stolen information includes name, phone number, email addresses, passport number and in some cases credit card numbers and expiry dates. While the company is still taking measures to do damage control for the second biggest breach in history (after Yahoo’s data breach), here is what consumers can do to protect themselves:
- Look out for any suspicious activity on your bank account. Continuously monitor all activities and immediately report any unauthorised transactions
- Limit information you share with your company. A travel company may ask for your passport number, but customers can also provide a different form of identification. Try not saving credit card details on untrusted websites
- Reset any reused passwords associated with your Starwood account. Select strong passwords that are difficult to predict and consider using a password manager.
- Look out for updates from Marriot but be aware of phishing emails trying to take advantage of the news relating to the breach.
Privasec's COO, Karan Khosla Interviewed by ICE71
Privasec is really proud to be a part of ICE71; Singapore's first cybersecurity startup hub, aimed at growing Singapore's cybersecurity ecosystem. Privasec’s COO, Karan Khosla shared his thoughts on hacking and data breaches in a recent interview with ICE71. Here are some key takeaways from his interview:
- It is not a question of IF but WHEN a company will be hacked.
- Preparation is key. Many companies are now realising the value of incident response war room training - walking through an incident to practice what to do and being prepared for security incidents.
- Individuals need to become better prepared and start protecting themselves from data breaches. Keeping systems up to date and using strong passwords is critical.
Dealing with a Data Breach
The 2019 Threat Report produced by Sophos provides an in-depth analysis of key cyber-attack trends. Here are some key highlights:
- Prepare for ransomware attacks:The report analyses ransomware attacks (e.g. WannaCry, Dharma and SamSam) and argues that the worst manual ransomware attacks started when “the attacker discovered that an administrator had opened a hole in the firewall for a Windows computer’s remote desktop”. Using multi-factor authentication (MFA) and limiting the use of domain admin credentials to dedicated machine(s) are effective tools to prevent ransomware. We also suggest developing an incident response plan (IRP), testing it, and training staff who need to know about it.
- Attacks via IoT devices: There has been significant growth in the numbers of attacks targeting IoT devices. Simple measures such as changing the default passwords to prevent reinfection is key as attacks targeting IoT devices are not slowing down.
- Practise the fundamentals: The report emphasises the importance of returning to the basics. This includes using of password manager and multi factor authentication where available. Do not store passwords in plain text. Be mindful of clicking on unknown links or opening unknown files or messages. Be careful of what you store in "the cloud".
