Government hackers attack port of Houston through Zoho vulnerability

Published

on

The CISA, the FBI, and the US Coast Guard have issued a joint warning about foreign attacks through the Zoho vulnerability.

A hacker group, allegedly funded by a certain state, attempted to attack the computer network of one of the largest ports in the United States, the Port of Houston. During the attack, the attackers intended to exploit a zero-day vulnerability in Zoho. This was announced on Thursday, September 23, by representatives of the Cyber ​​and Infrastructure Security Agency (CISA) at a hearing in the US Senate.

Port Authority stated that she was able to successfully repel the attack and “no operational data or systems were affected.” Following an investigation by the CISA, the FBI and the US Coast Guard published a joint warning to organizations in the United States of foreign country attacks through the Zoho vulnerability.

How reported CrowdStrike Senior Analyst Matt Dahl, the zero-day vulnerability has been exploited in attacks since August 2021.

Zoho fixed the vulnerability (CVE-2021-40539) on September 8th, and then CISA released his first warning of attacks. Who is behind the attacks is still unknown. CISA has not yet credited the attempted hacking of the Port of Houston computer network to any particular group.

“Of course, the most sophisticated attackers go to great lengths, as in the case of SolarWinds, to cover their tracks and hide their presence in order to stay on the networks for extended periods of time and extract data. But we are working very closely with our interagency partners and the intelligence community to better understand the actors of threats and can not only protect systems, but ultimately bring these actors to justice, ”- said the leadership of CISA.

Hacker who earned 27 million in cyberattacks will spend 20

A Florida district court has sentenced 34-year-old IT engineer Sebastien Vashon-Desjardins to 20 years in prison for carrying out at least 90 cyberattacks.

Hacker who earned $27 million in cyberattacks will spend 20 years in prison and pay $21 million in fines

It is noted that for several years of his activity, the hacker, using the NetWalker encryption virus, earned about $ 27 million. A search of Vashon-Desjardins revealed a crypto wallet containing 719 bitcoins, which was about $22 million at the time of the cybercriminal’s arrest in January 2022.

According to investigators, the 34-year-old cybercriminal acted in collusion with other hackers. Vashon-Desjardins himself played the role of an attacker: he infected the corporate networks of various companies with a virus and then demanded a ransom from them. Organizations from the USA, Canada and a number of European countries suffered from the activities of the criminal.

It is noted that, in addition to the prison term, the court also imposed a fine on Vashon-Desjardins in the amount of $ 21 million. Also, the criminal will have to pay compensation to the companies affected by his actions. The amount of damages has not yet been established.

Recently, various vulnerabilities in processors have been talked about much less often, and users no longer worry about performance degradation due to patches. As it turns out, Ryzen 7000 processors generally benefit from such patches!

At least this is true for Linux, since it was in this OS that the author tested the Ryzen 9 7950X and Ryzen 5 7600X. It turned out that when working out of the box, the CPUs show better performance than when loading a special version of Linux with a deactivated patch from the Specter V2 vulnerability.

Of course, such results do not appear everywhere, and during normal work they are unlikely to be critical. In particular, in total, according to the results of 190 tests, the difference was only 3%.

PlayStation 5 has been hacked. You can install games, but you can’t run them yet

PlayStation 5 has been hacked You can install games but

Nearly two years after the PlayStation 5 went on sale, modders have found a way to jailbreak the console, albeit with some restrictions.

IGN notes that the modder, known as SpecterDev, disclosed an apparent jailbreak that is described as an experimental IPV6 kernel exploit exploiting a WebKit vulnerability.

The jailbreak will only work on PS5 systems with firmware 4.03 or later. If you’ve updated your PS5 since October last year, you won’t be able to try the exploit. But even if you need firmware, an attempt to install a jailbreak works only in a third of cases.

As for what you can do with a jailbroken PS5 right now, you’ll get access to the system’s debug menu. You can also install games from outside the PlayStation Store, but you cannot run third-party software.

Modder Lance McDonald tested the jailbreak and was able to install the PT demo, the famous teaser of the canceled Silent Hills game. However, he was unable to start playing the game. Although the exploit offers read/write access to the PS5, there is currently no way to execute the downloaded files. In any case, PT is not backwards compatible with PS5.

It is currently unlikely that this jailbreak will be widely used anytime soon due to its limitations and the fact that Sony can ban modder accounts. On top of that, there is a risk of locking the console at that time. However, it may give other hackers and modders a foundation to build more robust jailbreak tools.
