Chinese Hackers Targeted Dozens of Industrial Enterprises and Public Institutions

Chinese Hackers Targeted Dozens of Industrial Enterprises and Public Institutions

August 09, 2022Ravie Lakshmanan
Over a dozen military-industrial complex enterprises and public institutions in Afghanistan and Europe have come under a wave of targeted attacks since January 2022 to steal confidential data by simultaneously making use of six different backdoors. Russian cybersecurity firm Kaspersky  attributed  the attacks "with a high degree of confidence" to a China-linked threat actor tracked by  Proofpoint  as  TA428 , citing overlaps in tactics, techniques, and procedures (TTPs).  TA428, also tracked under the names Bronze Dudley, Temp.Hex, and Vicious Panda, has a  history  of striking entities in Ukraine, Russia, Belarus, and Mongolia. It's believed to share connections with another hacking group called Mustang Panda (aka Bronze President). Targets of the latest cyber espionage campaign included industrial plants, design bureaus and research institutes, government agencies, ministries and departments in several East European countries and Afghanistan. Attack chains entail
New Orchard Botnet Uses Bitcoin Founder’s Account Info to Generate Malicious Domains

New Orchard Botnet Uses Bitcoin Founder's Account Info to Generate Malicious Domains

August 08, 2022Ravie Lakshmanan
A new botnet named Orchard has been observed using Bitcoin creator Satoshi Nakamoto's account transaction information to generate domain names to conceal its command-and-control (C2) infrastructure. "Because of the uncertainty of Bitcoin transactions, this technique is more unpredictable than using the common time-generated [ domain generation algorithms ], and thus more difficult to defend against," researchers from Qihoo 360's Netlab security team said in a Friday write-up. Orchard is said to have undergone three revisions since February 2021, with the botnet primarily used to deploy additional payloads onto a victim's machine and execute commands received from the C2 server. It's also designed to upload device and user information as well as infect USB storage devices to propagate the malware. Netlab's analysis shows that over 3,000 hosts have been enslaved by the malware to date, most of them located in China. Orchard has also been subjected to
The Benefits of Building a Mature and Diverse Blue Team

The Benefits of Building a Mature and Diverse Blue Team

August 08, 2022The Hacker News
A few days ago, a friend and I were having a rather engaging conversation that sparked my excitement. We were discussing my prospects of becoming a red teamer as a natural career progression. The reason I got stirred up is not that I want to change either my job or my position, as I am a happy camper being part of Cymulate's blue team. What upset me was that my friend could not grasp the idea that I wanted to keep working as a blue teamer because, as far as he was concerned, the only natural progression is to move to the red team.  Red teams include many roles ranging from penetration testers to attackers and exploit developers. These roles attract most of the buzz, and the many certifications revolving around these roles (OSCP, OSEP, CEH) make them seem fancy. Movies usually make hackers the heroes, while typically ignoring the defending side, the complexities and challenges of blue teamers' roles are far less known. While blue teams' defending roles might not sound as
Researchers Uncover Classiscam Scam-as-a-Service Operations in Singapore

Researchers Uncover Classiscam Scam-as-a-Service Operations in Singapore

August 08, 2022Ravie Lakshmanan
A sophisticated scam-as-a-service operation dubbed Classiscam has now infiltrated into Singapore, more than 1.5 years after  expanding to Europe . "Scammers posing as legitimate buyers approach sellers with the request to purchase goods from their listings and the ultimate aim of stealing payment data," Group-IB  said  in a report shared with The Hacker News. The cybersecurity firm called the operators a "well-coordinated and technologically advanced scammer criminal network." Classiscam refers to a  Russia-based cybercrime operation  that was first recorded in summer 2019 but only came under spotlight a year later coinciding with a surge in activity owing to an increase in online shopping in the aftermath of COVID-19 outbreak. Called the  most widely used fraud scheme  during the pandemic, Classiscam targets people who use marketplaces and services relating to property rentals, hotel bookings, online bank transfers, online retail, ride-sharing, and package de

Meta Cracks Down on Cyber Espionage Operations in South Asia Abusing Facebook

August 08, 2022Ravie Lakshmanan
Facebook parent company Meta disclosed that it took action against two espionage operations in South Asia that leveraged its social media platforms to distribute malware to potential targets. The first set of activities is what the company described as "persistent and well-resourced" and undertaken by a hacking group tracked under the moniker Bitter APT (aka APT-C-08 or T-APT-17) targeting individuals in New Zealand, India, Pakistan, and the U.K. "Bitter used various malicious tactics to target people online with social engineering and infect their devices with malware," Meta  said  in its Quarterly Adversarial Threat Report. "They used a mix of link-shortening services, malicious domains, compromised websites, and third-party hosting providers to distribute their malware." The attacks involved the threat actor creating fictitious personas on the platform, masquerading as attractive young women in a bid to build trust with targets and lure them into cl
New IoT RapperBot Malware Targeting Linux Servers via SSH Brute-Forcing Attack

New IoT RapperBot Malware Targeting Linux Servers via SSH Brute-Forcing Attack

August 06, 2022Ravie Lakshmanan
A new IoT botnet malware dubbed RapperBot has been observed rapidly evolving its capabilities since it was first discovered in mid-June 2022. "This family borrows heavily from the original  Mirai source code , but what separates it from other IoT malware families is its built-in capability to brute force credentials and gain access to SSH servers instead of Telnet as implemented in Mirai," Fortinet FortiGuard Labs  said  in a report. The malware, which gets its name from an embedded URL to a YouTube rap music video in an earlier version, is said to have amassed a growing collection of compromised SSH servers, with over 3,500 unique IP addresses used to scan and brute-force their way into the servers. RapperBot's current implementation also delineates it from Mirai, allowing it to primarily function as an SSH brute-force tool with limited capabilities to carry out distributed denial-of-service (DDoS) attacks. The deviation from traditional Mirai behavior is further
Hackers Exploit Twitter Vulnerability to Exposes 5.4 Million Accounts

Hackers Exploit Twitter Vulnerability to Exposes 5.4 Million Accounts

August 06, 2022Ravie Lakshmanan
Twitter on Friday revealed that a now-patched zero-day bug was used to link phone numbers and emails to user accounts on the social media platform. "As a result of the vulnerability, if someone submitted an email address or phone number to Twitter's systems, Twitter's systems would tell the person what Twitter account the submitted email addresses or phone number was associated with, if any," the company  said  in an advisory. Twitter said the bug, which it was  made aware  of in January 2022, stemmed from a code change introduced in June 2021. No passwords were exposed as a result of the incident. The six-month delay in making this public stems from new evidence last month that an unidentified actor had potentially taken advantage of the flaw before the fix to scrape user information and sell it for profit on  Breach Forums . Although Twitter didn't reveal the exact number of impacted users, the forum post made by the threat actor shows that the flaw was pr
