Update Windows 10 Now to Block SMBGhost Vulnerability


When even the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency is starting to get nervous about your unpatched Windows 10 system, maybe it’s time to make sure you’ve downloaded everything you need from Windows Update.

This time around, the agency is reacting to the emergence of new proof-of-concept attacks related to a vulnerability that was discovered in March—yes, three months ago. The exploit, “SMBGhost,” take advantage of an issue with Windows’ server message block protocol that could give an attacker unrestricted access to run whatever they want on an affected machine. (That includes servers, obviously, but also any unpatched clients connecting to one that has already been hit.)

Zoom's Security and Privacy Woes Violated GDPR, Expert Says


Homeworking and learning have led to a boom in videoconferencing, with Zoom a major beneficiary. But concerns over privacy and security raise important questions: is Zoom safe, and is it even GDPR compliant?

Security concerns revolve around the recent discovery of several vulnerabilities taken with the length of time it has taken Zoom to fix earlier vulnerabilities. Privacy concerns focus on a lack of transparency around the user or meeting data retained by Zoom, and who else has access to it. We will concentrate on the privacy issues in this article.
Data retention and third-party access concerns are typified by the recent discovery that the Zoom iOS app had been passing data to Facebook even where the iOS user had no Facebook account. There was no indication in Zoom's privacy policy that this was happening (Zoom has stopped this, but iOS users will need to download the latest app version to prevent it continuing).

HIPAA\HITECH Demystified - And What Could It Cost Me?


HIPAA (Health Insurance Portability and Accountability Act of 1996) is United States legislation that provides data privacy and security provisions for safeguarding medical information. The law has emerged into greater prominence in recent years with the proliferation of health data breaches caused by cyberattacks and ransomware attacks on health insurers and providers.

What is the purpose of HIPAA?

HIPAA, also known as Public Law 104-191, has two main purposes: to provide continuous health insurance coverage for workers who lose or change their job and to reduce the administrative burdens and cost of healthcare by standardizing the electronic transmission of administrative and financial transactions. Other goals include combating abuse, fraud, and waste in health insurance and healthcare delivery and improving access to long-term care services and health insurance.

Google Reveals How To Hack An Apple iPhone Within Minutes


Apple iPhones are considered secure devices, but that doesn’t mean they aren’t open to hacking. And yesterday, Google Project Zero’s ethical hackers showed just how easy it can be to access your iPhone or iPad without your knowledge.

Armed only with a user’s Apple ID, security researcher Samuel Groß was able to remotely hack an iPhone within minutes, stealing passwords, text messages, and emails.

Leveraging just one vulnerability labeled CVE-2019-8641, Groß was also able to remotely activate an Apple iPhone’s microphone and camera without any interaction from the user. In simple terms, this means an attacker could gain access to your iPhone without you clicking a malicious URL.

Got Backups?


If you use a computer or mobile device long enough, something will eventually go wrong. You may accidentally delete the wrong files, have a hardware failure, or lose a device. Even worse, malware, such as ransomware, may wipe your files and/or hold them captive. At times like these, backups are often the only way you can rebuild your digital life.


Backups are copies of your information stored somewhere other than on your computer or mobile device. When you lose valuable data, you can recover your data from backups. The first step is deciding what you want to back up: specific data that is important to you or everything, including your entire operating system. Many backup solutions are configured by default to use the first approach. They back up the most commonly used folders. If you are not sure what to back up or want to be extra careful, back up everything.

Scamming You Through Social Media


Many of us have received phishing email, either at work or at home. These emails look legitimate, such as from your bank, your boss, or your favorite online store, but are really an attack, attempting to pressure or trick you into taking an action you should not take, such as opening an infected email attachment, sharing your password, or transferring money. The challenge is, the savvier we become at spotting and stopping these email attacks, the more cybercriminals try other ways of contacting and scamming us.
