Extortion DDoS Attacks See Significant Increase in 2021

Published

on

Distributed denial of service attacks (DDoS) accompanied by ransom requests to stop the malicious campaign had a significant increase in the fourth quarter of 2021, growing 175% compared to the previous period. That’s what a report released by Cloudflare on Tuesday (10) points out.

According to the firm specializing in online security and content distribution, among other services, a quarter of its customers were DDoS attacks with extortion threats in the last three months of last year. Most of them happened in December, when companies received twice as many ransom requests as they did in November.

The company also reported that the annual number of malicious campaigns of this type increased by 29% compared to the number recorded in 2020. They began to become a threat in the middle of that year and have since become increasingly common and complex.

The document also details the growth of application layer DDoS attacks, which prevent users from accessing a particular service, which increased by 641% in the fourth quarter. Likewise, the network layer DDoS attacks, aimed at taking down the entire cyber infrastructure of the target, had a significant evolution in the period.

Even though it is not an advanced cyber-attack technique, DDoS has proven to be effective, raising awareness among security experts. In this type of campaign, servers and the online infrastructure of companies and entities receive huge amounts of simultaneous accesses, making the network slow or completely offline.

According to Cloudflare, the biggest targets of cybercriminals that use this method are large retailers, streaming services and networks owned by local governments. Cloud-based business apps and online gaming platforms are other victims much sought after by attackers.

“A little closer to Mars” – Elon Musk showed record tests of the largest SpaceX rocket

A little closer to Mars Elon Musk showed record

Elon Musk has confirmed that SpaceX has completed a lengthy static fire test of the Booster 7 Raptor 2 engines on the orbital launch pad at Starbase.

On Tuesday, SpaceX tested its super-heavy rocket for about 12 seconds, making it the longest launch to date. The test, which fired 11 of the 33 Raptor 2 rocket engines, passed without any explosions or other problems, which is an excellent result.

Earlier this month, SpaceX fired 14 Raptor 2 engines on that booster for a few seconds, so yesterday’s test didn’t set a new record for most engines tested. However, this “long” test was the longest ever to run so many Raptor 2 engines at the same time.

Earlier, SpaceX founder Elon Musk said the next step would be to fire some of the Super Heavy engines for about 20 seconds to test autogenous boost. This method of pressurizing fuel tanks uses gases generated aboard the rocket rather than a separately loaded inert gas such as helium.

It looks like SpaceX still has a couple of key tests to complete before the super-heavy Starship rocket launches from the Starbase site in South Texas. SpaceX is expected to conduct at least a brief test run of all 33 Raptor engines at the same time to ensure that the entire complex is fueled and pressurized in the rocket’s propulsion system. The Starship will then be installed on top of the Super Heavy for final testing.

Samsung is preparing a smartphone that will be weaker than its predecessor two years ago. Galaxy M54 will receive SoC Exynos 1380

Samsung is preparing a smartphone that will be weaker than

Smartphone Samsung Galaxy M54 lit up in the Geekbench database. Unfortunately, as previously reported, he will not receive any SoC Snapdragon 888, although this is expected.

Samsung’s mid-budget novelty will receive the same platform as the Galaxy A54. Probably, the Galaxy A34 will also receive it.

We are talking about the not yet presented Exynos 1380, which will replace the Exynos 1280. In the benchmark, the new SoC scores 750 and almost 2700 points in single-threaded and multi-threaded modes, respectively. And this is almost the level of Snapdragon 778G, that is, this is an excellent result for a mid-budget smartphone. True, we are only talking about processor performance, and we do not yet know which GPU the new SoC will receive.

It is also worth noting that the Galaxy M52 was also based on the Snapdragon 778G, and the Galaxy M53 received a slightly less productive Dimensity 900. Thus, the Galaxy M54 model, at least in terms of the processor part, will be slightly inferior even not to its predecessor, but to the device two years ago.

Bullitt Group and MediaTek want to launch a satellite enabled smartphone

The British manufacturer Bullitt Group, which produces devices under the brands CAT and Motorola, intends to release a smartphone with satellite communications. They want to implement this project together with the Chinese chipmaker MediaTek.

It is assumed that the new smartphone will provide calls and text data via satellite, although it is not yet clear how this will work. The device itself will be released in the first quarter of 2023.

The novelty has been developed for two years, so the project is nearing completion. According to Bullitt Group co-founder Richard Wharton, previously the seamless integration of satellite communications into a smartphone was accompanied by problems, but now they are solved.

The new phone will be the first to use MediaTek’s 3GPP NTN chipset. The software will keep track of what type of connection is currently being used – Wi-Fi or cellular network. The connection to the satellite will be carried out only in the absence of both of these options.

It is claimed that the time to connect to the satellite and send a message is about 10 seconds. This is longer than a regular connection, but still pretty fast.

Note that Apple already has this and Samsung will soon have it.
