DoNot Team Hackers Updated its Malware Toolkit with Improved Capabilities

DoNot Team Hackers Updated its Malware Toolkit with Improved Capabilities

August 19, 2022Ravie Lakshmanan
The Donot Team threat actor has updated its Jaca Windows malware toolkit with improved capabilities, including a revamped stealer module designed to plunder information from Google Chrome and Mozilla Firefox browsers. The improvements also include a new infection chain that incorporates previously undocumented components to the modular framework, Morphisec researchers Hido Cohen and Arnold Osipov  disclosed  in a report published last week. Also known as APT-C-35 and Viceroy Tiger, the Donot Team is known for setting its sights on defense, diplomatic, government, and military entities in India, Pakistan, Sri Lanka, and Bangladesh, among others at least since 2016. Evidence unearthed by Amnesty International in October 2021  connected  the group's attack infrastructure to an Indian cybersecurity company called Innefu Labs. Spear-phishing campaigns containing malicious Microsoft Office documents are the preferred delivery pathway for malware, followed by taking advantage of m
Cybercrime Group TA558 Targeting Hospitality, Hotel, and Travel Organizations

Cybercrime Group TA558 Targeting Hospitality, Hotel, and Travel Organizations

August 19, 2022Ravie Lakshmanan
A financially motivated cybercrime group has been linked to an ongoing wave of attacks aimed at hospitality, hotel, and travel organizations in Latin America with the goal of installing malware on compromised systems. Enterprise security firm Proofpoint, which is tracking the group under the name TA558 dating all the way back to April 2018, called it a "small crime threat actor." "Since 2018, this group has used consistent tactics, techniques, and procedures to attempt to install a variety of malware including Loda RAT, Vjw0rm, and Revenge RAT," the company's threat research team  said  in a new report. The group has been operational at a higher tempo in 2022 than usual, with intrusions mainly geared towards Portuguese and Spanish speakers in Latin America, and to a lesser extent in Western Europe and North America. Phishing campaigns mounted by the group involve sending malicious spam messages with reservation-themed lures such as hotel bookings that cont
Google Cloud Blocks Record DDoS attack of 46 Million Requests Per Second

Google Cloud Blocks Record DDoS attack of 46 Million Requests Per Second

August 19, 2022Ravie Lakshmanan
Google's cloud division on Thursday disclosed it mitigated a series of HTTPS distributed denial-of-service (DDoS) attacks which peaked at 46 million requests per second (RPS), making it the largest such recorded to date. The attack, which occurred on June 1, targeting an unnamed Google Cloud Armor customer, is 76% larger than the  26 million RPS DDoS attack  repealed by Cloudflare earlier this June. "To give a sense of the scale of the attack, that is like receiving all the daily requests to Wikipedia (one of the top 10 trafficked websites in the world) in just 10 seconds," Google Cloud's Emil Kiner and Satya Konduru  said . It's said to have started around 9:45 a.m. PT with 10,000 RPS, before growing to 100,000 RPS eight minutes later and further ramping up within two minutes to hit a high of 46 million RPS at 10:18 a.m. PT. In all, the DDoS assault lasted for a total of 69 minutes. Google said that the unexpectedly high volume of traffic originated from 5
New Amazon Ring Vulnerability Could Have Exposed All Your Camera Recordings

New Amazon Ring Vulnerability Could Have Exposed All Your Camera Recordings

August 19, 2022Ravie Lakshmanan
Retail giant Amazon patched a high-severity security issue in its Ring app for Android in May that could have enabled a rogue application installed on a user's device to access sensitive information and camera recordings. The Ring app for Android has over 10 million downloads and enables users to monitor video feeds from smart home devices such as video doorbells, security cameras, and alarm systems. Amazon acquired the doorbell maker for about $1 billion in 2018. Application security firm Checkmarx  explained  it identified a cross-site scripting (XSS) flaw that it said could be weaponized as part of an attack chain to trick victims into installing a malicious app. The app can then be used to get hold of the user's Authorization Token, that can be subsequently leveraged to extract the session cookie by sending this information alongside the device's hardware ID, which is also encoded in the token, to the endpoint "ring[.]com/mobile/authorize."

Researchers Detail Evasive DarkTortilla Crypter Used to Deliver Malware

Researchers Detail Evasive DarkTortilla Crypter Used to Deliver Malware

August 18, 2022Ravie Lakshmanan
A .NET-based evasive crypter named  DarkTortilla  has been used by threat actors to distribute a broad array of commodity malware as well as targeted payloads like Cobalt Strike and Metasploit, likely  since 2015 . "It can also deliver 'add-on packages' such as additional malicious payloads, benign decoy documents, and executables," cybersecurity firm Secureworks  said  in a Wednesday report. "It features robust anti-analysis and anti-tamper controls that can make detection, analysis, and eradication challenging." Malware delivered by the crypter includes information steakers and remote access trojans (RATs) such as Agent Tesla, AsyncRat, NanoCore, and RedLine Stealer. "DarkTortilla has versatility that similar malware does not," the researchers noted. Crypters are  software tools  that use a  combination  of encryption, obfuscation, and code manipulation of malware so as to  bypass detection  by security solutions. The delivery of DarkTortil
China-backed APT41 Hackers Targeted 13 Organisations Worldwide Last Year

China-backed APT41 Hackers Targeted 13 Organisations Worldwide Last Year

August 18, 2022Ravie Lakshmanan
The Chinese advanced persistent threat (APT) actor tracked as Winnti has targeted at least 13 organizations geographically spanning across the U.S, Taiwan, India, Vietnam, and China against the backdrop of four different campaigns in 2021. "The targeted industries included the public sector, manufacturing, healthcare, logistics, hospitality, education, as well as the media and aviation," cybersecurity firm Group-IB  said  in a report shared with The Hacker News. This also included the attack on Air India that came to light in June 2021 as part of a campaign codenamed  ColunmTK . The other three campaigns have been assigned the monikers DelayLinkTK, Mute-Pond, and Gentle-Voice based on the domain names used in the attacks. APT41, also known as Barium, Bronze Atlas, Double Dragon, Wicked Panda, or Winnti, is a  prolific   Chinese   cyber threat group  that's known to carry out state-sponsored espionage activity in parallel with financially motivated operations at least
Hackers Using Bumblebee Loader to Compromise Active Directory Services

Hackers Using Bumblebee Loader to Compromise Active Directory Services

August 18, 2022Ravie Lakshmanan
The malware loader known as Bumblebee is being increasingly co-opted by threat actors associated with BazarLoader, TrickBot, and IcedID in their campaigns to breach target networks for post-exploitation activities. "Bumblebee operators conduct intensive reconnaissance activities and redirect the output of executed commands to files for exfiltration," Cybereason researchers Meroujan Antonyan and Alon Laufer  said  in a technical write-up. Bumblebee  first came to light in March 2022 when Google's Threat Analysis Group (TAG) unmasked the activities of an initial access broker dubbed  Exotic Lily  with ties to the  TrickBot  and the larger  Conti  collectives. Typically delivered via initial access acquired through spear-phishing campaigns, the modus operandi has since been tweaked by eschewing macro-laced documents in favor of ISO and LNK files, primarily in response to Microsoft's decision to  block macros by default .
