During the first half of 2021, 7.3 million ransomware-related cyber incidents were recorded.
Banks and large companies around the world have been hit hard by the surge in cyber ransomware attacks. How noted experts from Trend Micro, in 2021, the number of these attacks increased by 1318% compared to last year.
Ransomware has become one of the most prevalent cyber threats to businesses today. This year alone, there have been major attacks on the computer systems of the fuel giant Colonial Pipeline, MSP provider Kaseya and the Irish healthcare system, etc.
In this cybercrime area, experts have noted a number of trends:
The most attractive targets for ransomware are organizations with more than $ 100 million in annual revenue;
Entry-level brokers have become a well-established criminal business and often seek cooperation with extortionist groups;
Ransomware operators now often threaten to leak confidential data stolen during an attack if the victim refuses to pay the ransom;
Researchers have found that criminals have begun to form so-called “cartels,” in which ransomware operators exchange information and tactics.
During the first six months of 2021, there were 7.3 million ransomware-related cyber incidents, most of which were variants of WannaCry and Locky.
Attackers also make extensive use of open source penetration testing tools and legitimate solutions. Cobalt Strike, PsExec, Mimikatz and Process Hacker are found in the arsenals of the Clop, Conti, Maze and Sodinokibi factions.
Hackers hacked Tesla twice, for which they received 350 thousand dollars and Tesla Model 3
As part of Pwn2Own’s Vancouver-based commercial vulnerability finding event, a French team called Synacktiv managed to hack into Tesla systems twice.
On the first day, Synacktiv successfully performed a TOCTOU (Time-of-check to time-of-use) attack on the Tesla Gateway, and the group was rewarded with a $100,000 cash reward and a Tesla Model 3 car. And the next day hackers broke into the Tesla infotainment system, and received another 250 thousand dollars for this.
The Tesla cybersecurity team is already analyzing the actions of hackers in order to eliminate the vulnerabilities found with a firmware update.
Scissors undercut: Windows 11 vulnerability reveals sensitive information from screenshots, including deleted parts
A dangerous vulnerability has been discovered in one of the standard Windows 11 applications that could lead to the disclosure of sensitive information to the user. Moreover, at the moment the vulnerability is not closed and attackers can use it.
We are talking about the application Snipping Tool (Scissors). The vulnerability, called aCropalypse, allows you to undo changes made by a user when editing a screenshot, including cropped or blurred parts that hide sensitive data.
When you edit a screenshot, you can save it with the same name as the original file by overwriting it. However, as it turns out, the Windows 11 Snipping Tool does not remove the original information from the file, but simply leaves it added at the end, which is usually invisible to users. With some trickery, a potential attacker can extract hidden information from a file and see what information has been edited.
As you can see, edited screenshots are usually much larger due to the inclusion of information from the original image.
This is a pretty serious vulnerability. For example, if you share a screenshot of an order confirmation page on Amazon, it may contain an address, the same goes for credit card numbers and other sensitive data.
In 2018, Google had an AI ready for a ChatGPT-style chatbot, but it was closed due to security issues.
In recent months, the ChatGPT chatbot has been on the news pages, and this has forced many companies to catch up with OpenAI. Among them are Microsoft, Google and a number of Chinese corporations. However, reportedly, the situation could be different.
As early as 2018, Google is said to have had a natural language processing AI similar to ChatGPT. However, company executives closed the project, considering it too dangerous. One of the developers was research engineer Daniel De Freitas, and Noam Shazeer, a software engineer at Google, also contributed to the project.
The project was called Meena and was a chatbot that could talk about different topics. With him you could discuss TV shows, have discussions about philosophy and joke. At the same time, the developers believed that this technology could be added to the search engine, however, in the end, Google stopped development. The company said the bot did not meet its AI security standards.
Note that later, on the basis of these developments, the LaMDA chat bot was created, which flies into the basis of Bard. Thus, the development nevertheless reached the mass user, albeit with a great delay.
