CISA issues warning against extortionist group Conti

Published

on

In total, more than 400 attacks were recorded using the Conti ransomware.

Cyber ​​and Infrastructure Security Agency (CISA) published Conti ransomware newsletter. The document for the cybersecurity community provided detailed information about the group and its partners.

In total, more than 400 Conti ransomware attacks have been recorded targeting American organizations and international businesses, according to CISA and the FBI. CISA provided technical information on how the ransomware group operates and what steps organizations can take to prevent potential attacks.

While Conti uses an ransomware-as-a-service business model, the group operates in a slightly different way from other criminals, experts noted. According to CISA, the group does not pay partners a part of the ransom proceeds, but pays wages.

According to the director of cybersecurity of the NSA, Rob Joyce (Rob Joyce), Conti’s operators are targeting critical infrastructure. The number of attacks using Conti is increasing. Joyce urged organizations to use multifactor authentication, segment their networks, scan them for vulnerabilities, and keep abreast of all fixes.

Conti members use a variety of methods and tools to infiltrate systems, including targeted phishing campaigns, remote monitoring and control software, and remote desktop software.

The targeted phishing campaigns used emails containing malicious attachments or links. Malicious Microsoft Word attachments often contain embedded scripts to download or install other malware such as TrickBot and IcedID and / or Cobalt Strike.

Sometimes the group and its partners use tools that are already on the victim’s network, or they run Windows Sysinternals and Mimikatz to steal plaintext credentials. In this way, hackers elevate privileges on the system and perform other tasks after exploitation and moving around the network.

Cryptocurrency exchange Binance was robbed of 570 million Hacker withdrew

Cryptocurrency exchange Binance has undergone another hacker attack. The attackers managed to withdraw BNB tokens worth about $570 million.

Cryptocurrency exchange Binance was robbed of $570 million.  Hacker withdrew BNB tokens

Somewhat earlier it was reported that the attack allowed the hackers to steal about $110 million, but now it turned out that everything is much worse. At the same time, the specialists of the exchange managed to freeze part of the funds, but we are talking about only 7 million dollars, which is clearly insignificant against the background of 570 million.

The exchange revealed that a cross-chain bridge connected to its BNB chain was attacked, allowing hackers to move BNB tokens off the network. Now the network has been restored, and the clients’ funds, according to Binance, are safe.

The fact of the theft of funds contributed to a sharp drop in the BNB rate by almost 5%, but after a few hours, almost half of the fall was redeemed.

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.

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%.
