Hive Ransomware Upgrades to Rust for More Sophisticated Encryption Method

Hive Ransomware Upgrades to Rust for More Sophisticated Encryption Method

July 06, 2022Ravie Lakshmanan
The operators of the Hive ransomware-as-a-service (RaaS) scheme have overhauled their file-encrypting software to fully migrate to Rust and adopt a more sophisticated encryption method. "With its latest variant carrying several major upgrades, Hive also proves it's one of the fastest evolving ransomware families, exemplifying the continuously changing ransomware ecosystem," Microsoft Threat Intelligence Center (MSTIC)  said  in a report on Tuesday. Hive , which was first observed in June 2021, has emerged as one of the most prolific RaaS groups,  accounting  for 17 attacks in the month of May 2022 alone, alongside  Black Basta and Conti . The shift from GoLang to Rust makes Hive the second ransomware strain after  BlackCat  to be written in the programming language, enabling the malware to gain additional benefits such as memory safety and deeper control over low-level resources as well as make use of a wide range of cryptographic libraries. What it also affords is
As New Clues Emerges, Experts Wonder: Is REvil Back?

As New Clues Emerges, Experts Wonder: Is REvil Back?

July 05, 2022The Hacker News
Change is a part of life, and nothing stays the same for too long, even with hacking groups, which are at their most dangerous when working in complete silence. The notorious REvil  ransomware  gang, linked to the infamous JBS and Kaseya, has resurfaced three months after the arrest of its members in Russia. The Russian domestic intelligence service, the FSB, had caught 14 people from the gang. In this apprehension, the 14 members of the gang were found in possession of 426 million roubles, $600,000, 500,000 euros, computer equipment, and 20 luxury cars were brought to justice. REvil Ransomware Gang- The Context The financially-motivated cybercriminal threat group Gold Southfield controlled ransomware group known as REvil emerged in 2019 and spread like wildfire after extorting $11 million from the meat-processor JBS. REvil would incentivize its affiliates to carry out cyberattacks for them by giving a percentage of the ransom pay-outs to those who help with infiltration activitie
Researchers Share Techniques to Uncover Anonymized Ransomware Sites on Dark Web

Researchers Share Techniques to Uncover Anonymized Ransomware Sites on Dark Web

July 05, 2022Ravie Lakshmanan
Cybersecurity researchers have detailed the various measures ransomware actors have taken to obscure their true identity online as well as the hosting location of their web server infrastructure. "Most ransomware operators use hosting providers outside their country of origin (such as Sweden, Germany, and Singapore) to host their ransomware operations sites," Cisco Talos researcher Paul Eubanks  said . "They use VPS hop-points as a proxy to hide their true location when they connect to their ransomware web infrastructure for remote administration tasks." Also prominent are the use of the TOR network and DNS proxy registration services to provide an added layer of anonymity for their illegal operations. But by taking advantage of the threat actors' operational security missteps and other techniques, the cybersecurity firm disclosed last week that it was able to identify TOR hidden services hosted on public IP addresses, some of which are previously unknown in
Ex-Canadian Government Employee Pleads Guilty Over NetWalker Ransomware Attacks

Ex-Canadian Government Employee Pleads Guilty Over NetWalker Ransomware Attacks

June 30, 2022Ravie Lakshmanan
A former Canadian government employee this week agreed to plead guilty in the U.S. to charges related to his involvement with the NetWalker ransomware syndicate. Sebastien Vachon-Desjardins , who was  extradited to the U.S.  on March 10, 2022, is accused of conspiracy to commit computer fraud and wire fraud, intentional damage to a protected computer, and transmitting a demand in relation to damaging a protected computer. The 34-year-old IT consultant from Gatineau, Quebec, was initially apprehended in January 2021 following a coordinated  law enforcement operation  to dismantle the dark web infrastructure used by the NetWalker ransomware cybercrime group to publish data siphoned from its victims. The takedown also brought its activities to a standstill. A search warrant executed at Vachon-Desjardins's home in Canada resulted in the seizure of 719 bitcoin, valued at approximately $28.1 million at the time, and $790,000 in Canadian currency. In February 2022, the Ontario Court o
Cybersecurity Experts Warn of Emerging Threat of "Black Basta" Ransomware

Cybersecurity Experts Warn of Emerging Threat of "Black Basta" Ransomware

June 27, 2022Ravie Lakshmanan
The Black Basta ransomware-as-a-service (RaaS) syndicate has amassed nearly 50 victims in the U.S., Canada, the U.K., Australia, and New Zealand within two months of its emergence in the wild, making it a prominent threat in a short window. "Black Basta has been observed targeting a range of industries, including manufacturing, construction, transportation, telcos, pharmaceuticals, cosmetics, plumbing and heating, automobile dealers, undergarments manufacturers, and more," Cybereason  said  in a report. Evidence indicates the ransomware strain was still in development as recently as February 2022, and only started to be used in attacks starting April after it was advertised on underground forums with an intent to buy and monetize corporate network access for a share of the profits. Similar to other ransomware operations, Black Basta is known to employ the tried-and-tested tactic of double extortion to plunder sensitive information from the targets and threaten to publish
