Kaspersky Warns of a Two-fold Surge in Browser Extensions that Steal Crypto

A browser extension is a piece of software that users can install to customise the functionality of a web browser. Browser extensions are handy, but they can also pose serious threats to privacy and security.
As an increasing number of people have begun to rely on cryptocurrencies for online transactions, cybercriminals have adapted their tactics accordingly: browser extensions have become an attractive target for hackers looking to exploit unsuspecting crypto users.
At the beginning of 2023 Kaspersky observed a two-fold increase in the number of malicious browser extensions, specifically those designed to perform web injects and steal cryptocurrency. There was also a rise in the number of malicious droppers that install harmful extensions on victims’ machines.
A malicious browser extension interferes in browser functionality and mimics legitimate software. It could be difficult to detect by antivirus software. Malicious extensions can alter what the user sees on his/her browser, as opposed to what is actually sent by the server.
For example, these extensions can add or remove text, labels, text fields, and other website elements. Malicious extensions can track affiliate IDs, engage in phishing activities and steal credentials, as well as steal cryptocurrency.
For instance, a malicious extension can insert an additional field to a form sent by a crypto wallet server. The purpose of these extra fields (accompanied by supporting labels and instructions) is to dupe the user into entering certain confidential information (e.g., login credentials, credit card numbers, CVVs, PINs, tokens, etc.) even if that information was not being requested by the crypto wallet in the original form.
These malicious extensions often mimic legitimate ones, making it difficult for users to differentiate between safe and harmful add-ons. Once installed, these extensions can inject malicious code into users’ browsers, enabling cybercriminals to steal sensitive information such as private keys, seed phrases for crypto wallets, login credentials and two-factor authentication information.
“Browser extensions can be installed both from official browser stores (e.g., in Chrome, Firefox) or direct from a file – this is currently available on Windows machines in the most popular browser – Chrome.
When installed from outside the official stores, the risk of the extension being malicious increases. Users, especially those who engage in cryptocurrency operations on their Windows machines, should be wary of browser extensions that they install,” comments Sergey Lozhkin, Lead Security Researcher at Kaspersky GReAT.

Huawei Unveils AI Computing System to Challenge Nvidia’s Flagship Product

China’s Huawei Technologies unveiled an AI computing system on Saturday that an industry expert said rivals Nvidia’s most advanced product, as the company aims to expand its footprint in the country’s booming AI sector.
The CloudMatrix 384 system made its public debut at the World Artificial Intelligence Conference (WAIC), a three-day event in Shanghai, attracting a large crowd to Huawei’s booth with its showcase of cutting-edge AI innovations.
The system has attracted significant interest from the global AI community since Huawei (HWT.UL) first introduced it in April. Industry analysts see it as a direct challenger to Nvidia’s GB200 NVL72, the most advanced system-level offering currently available from the U.S. chipmaker.
In an April article, Dylan Patel, founder of semiconductor research firm SemiAnalysis, stated that Huawei now possesses AI system capabilities that could surpass those of Nvidia.
Huawei staff at its WAIC booth declined to comment when asked to introduce the CloudMatrix 384 system.
A spokesperson for Huawei did not respond to questions.
Huawei has become widely regarded as China’s most promising domestic supplier of chips essential for AI development, even though the company faces U.S. export restrictions.
Nvidia CEO, Jensen Huang told Bloomberg in May that Huawei had been “moving quite fast” and named the CloudMatrix as an example.
The CloudMatrix 384 system features 384 of Huawei’s latest 910C chips and, according to SemiAnalysis, surpasses Nvidia’s GB200 NVL72 in certain performance metrics, despite the latter using 72 B200 chips.
SemiAnalysis attributes this performance advantage to Huawei’s strong system design, which offsets the lower power of individual chips by leveraging a greater number of them and incorporating system-level innovations.
Huawei describes the system as utilizing a “supernode” architecture that enables ultra-high-speed interconnectivity between chips.
In June, Zhang Pingan, CEO, Huawei Cloud confirmed that the CloudMatrix 384 was already operational on Huawei’s cloud platform.

Microsoft Servers Hacked by Chinese Groups

Chinese “threat actors” have hacked Microsoft’s SharePoint document software servers and targeted the data of the businesses using it, the firm has said.
China state-backed Linen Typhoon and Violet Typhoon as well as China-based Storm-2603 were said to have “exploited vulnerabilities” in on-premises SharePoint servers, the kind used by firms, but not in its cloud-based service.
The US tech giant has released security updates in response and has advised all on-premises SharePoint server customers to install them.
“Investigations into other actors also using these exploits are still ongoing,” Microsoft said in a statement.
The firm said it had “high confidence” the hackers would continue to target systems which have not installed its security updates.
It added that it would update its website blog with more information as its investigation continues.
Microsoft said it had observed attacks in which hackers had sent a request to a SharePoint server “enabling the theft of the key material by threat actors”.
Charles Carmakal, chief technology officer at Mandiant Consulting firm, a division of Google Cloud, told reporter, it was “aware of several victims in several different sectors across a number of global geographies”.
Carmakal said it appeared that governments and businesses that use SharePoint on their sites were the primary target.
A number of adversaries who stole material encoded by cryptography were then able to regain ongoing access to the victims’ SharePoint data, he said.
“This was exploited in a very broad way, very opportunistically before a patch was made available. That’s why this is significant,” Carmakal said.
Carmakal said the “China-nexus actor” was deploying techniques similar to previous campaigns associated with Beijing.
Microsoft said Linen Typhoon had “focused on stealing intellectual property, primarily targeting organizations related to government, defence, strategic planning, and human rights” for 13 years.
It added that Violet Typhoon had been “dedicated to espionage”, primarily targeting former government and military staff, non-governmental organizations, think tanks, higher education, the media, the financial sector and the health sector in the US, Europe, and East Asia.
Meanwhile, Storm-2603 was “assessed with medium confidence to be a China-based threat actor”.
