"Cyber conflicts are fought in the shadows, but in the case of Russia's invasion of Ukraine, it is a group that calls itself Anonymous that has made the most public declaration of war.

"Turkey on Wednesday launched an investigation after a hacker or hackers posted a database online containing the personal information of nearly 50 million Turkish citizens - more than half of the country's population - and a message taunting President Recep Tayyip Erdogan.

"The most well-documented of these deals with the hash function used to "anonymize" the license and medallion numbers. A bit of lateral thinking from one civic hacker and the data was completely de-anonymized. This data can now be used to calculate, for example, any driver's annual income. More disquieting, though, in my opinion, is the privacy risk to passengers. With only a small amount of auxiliary knowledge, using this dataset an attacker could identify where an individual went, how much they paid, weekly habits, etc. I will demonstrate how easy this is to do in the following section."

"A hacker has stolen millions of user account details from popular education platform Edmodo, and the data is apparently for sale on the so-called dark web.

"This person or group, who go by the names BestBuy and Popopret, recently spammed an ad to folks on Jabber, an instant messaging service. They offered to perform a distributed denial of service (DDoS) attack on whomever their client(s) wanted, and they backed up their offer by claiming to wield the ability to perform some of the strongest DDoS attacks ever seen. Recent events in the history of the internet show us that these kind of attacks - if these hackers indeed have the power they claim - can wreak internet havoc by blocking user access to a range of some of the web's most popular destinations."

"Twitter suffered a major security breach on Wednesday that saw hackers take control of the accounts of major public figures and corporations, including Joe Biden, Barack Obama, Elon Musk, Bill Gates, Jeff Bezos and Apple. The company confirmed the breach Wednesday evening, more than six hours after the hack began, and attributed it to a "coordinated social engineering attack" on its own employees that enabled the hackers to access "internal systems and tools"."

"Three software flaws in Facebook's systems allowed hackers to break into user accounts, including those of the top executives Mark Zuckerberg and Sheryl Sandberg, according to two people familiar with the investigation but not allowed to discuss it publicly.

Rather than merely address the problem, however, TerraCom and YourTel threatened the reporters, referring to them as "hackers" and accusing them of "numerous violations of the Computer Fraud and Abuse Act"

"A hacker is advertising what he says is more than one hundred million LinkedIn logins for sale. The IDs were reportedly sourced from a breach four years ago, which had previously been thought to have included a fraction of that number. At the time, the business-focused social network said it had reset the accounts of those it thought had been compromised."

"A giant database of intercepted Snapchat photos and videos has been released by hackers who have been collecting the files for years. Shocked users of the notorious chat forum 4chan are referring to the hack as "The Snappening," noting that this is far bigger than the iCloud hacks that recently targeted celebrities."

"One of the most widely used tools for monitoring and restricting pupils' internet use in UK schools has a serious security flaw which could leave hundreds of thousands of children's personal information exposed to hackers, a researcher has warned."

"Many people unwittingly sign up to be location-tracked 24/7, unaware that the highly sensitive data this generates is being used and sold on for profit.
