2. Russia Is Being Hacked at an Unprecedented Scale by Matt Burgess

Ukraine’s so-called “IT Army” has made a concerted effort over the past several months to make life as difficult as possible for Russia and its government, and recent reports suggest that they’ve been quite successful.

3. Creating Cyberattack Resilience in Modern Education Environments by Michael J. Covington

Due to the wealth of data available in K-12 schools’ systems, hackers are increasingly targeting these schools in cyberattacks. In fact, the K12 Security Information Exchange, a national non-profit that helps schools defend against cyberattacks, has tracked more than 1,200 cybersecurity incidents in U.S. public school systems since 2016. Thankfully, despite not always having the budget necessary to combat this growing threat, schools’ IT teams can take specific steps to protect themselves against attacks, including:

  • Increasing cybersecurity awareness
  • Practicing good security hygiene
  • Doing regular checkups on their inventory of assets
  • Inspecting network traffic and Internet use
  • Preventing unauthorized devices from operating on their networks
  • Make their cyber policies easily accessible

5. Android Security: We Stopped Billions of Harmful App Downloads, Says Google by Liam Tung

Google has made an effort to improve end user privacy and transparency in recent years beginning with its newly introduced data safety program this past May. Now, in a more targeted effort to combat malware and unwanted software, Google says it has blocked a total of 1.2 million apps from being published to their Play Store and has banned 190,000 bad developer accounts in 2021. In a recent blog post, Google’s Android and Privacy teams noted: “Last year we introduced multiple privacy-focused features, enhanced our protections against bad apps and developers, and improved SDK data safety. In addition, Google Play Protect continues to scan billions of installed apps each day across billions of devices to keep people safe from malware and unwanted software.”
