Apple’s Mail Privacy Protection not working on Apple Watch

Published

on

If the user viewed the email on Apple Watch and not on iPhone, the sender’s real IP address will be visible.

Developer and researcher under the pseudonym Mysk discovered that Apple’s Mail Privacy Protection does not work in the official Apple Watch Mail app.

This feature was introduced in iOS 15 and offers three types of privacy protections. Apple says it keeps location data secure, protects against tracking, and blocks marketing companies from seeing whether a user has opened an email or not.

Incoming emails can have hidden pixels that allow senders to know the recipient’s information. As soon as the user opens such a letter, the sender will receive information about his actions in the mail, and the recipient has no way to control the transmitted information. The sender can find out when and how many times the recipient opened the letter and whether it was forwarded to someone else, as well as learn the IP address and other data useful for creating a user profile and determining his location.

Mail Privacy Protection helps protect your privacy by blocking email senders (including Apple itself) from learning about user activity in email. When an email is received via the Apple Mail app, instead of downloading deleted content when the email is opened, Mail Privacy Protection by default downloads the deleted content in the background, regardless of whether the user opens the email or not. At the same time, Apple does not receive any data about the content.

In addition, all remote content downloaded by Apple Mail is routed through multiple proxies, preventing the sender from knowing the recipient’s IP address. Apple does not share the IP address of the sender, which would allow it to determine the location of the recipient. The proxy server network randomly assigns an IP address that matches only the region in which the device is located. Apple itself also has no access to the recipients’ IP addresses.

The feature can be activated for Apple Mail on iPhone, but it doesn’t work if you view emails (or even just previews) on Apple Watch, Mysk noted.

The researcher demonstrated his discovery by uploading an image to his server, pasting it into an email, and sending it. When Mysk checked the IP address where the image it sent was uploaded, it saw the real IP address of the Apple Watch.

Hackers hacked the BitMart crypto exchange and stole $ 150 million.

Published

The company is investigating the incident, and the withdrawal operations are temporarily suspended.

Crypto exchange BitMart reported that it was hacked, as a result of which it lost $ 150 million worth of cryptocurrency.

Exchange founder and CEO Sheldon Xia confirmed the incident and clarified that the vulnerability was related to hot wallets Ethereum (ETH) and Binance Smart Chain (BSC).

“We have identified a large-scale security breach involving one of our hot ETH wallets and one of our hot BSC wallets. At the moment, we are still drawing conclusions about the possible methods used. The hackers managed to withdraw assets worth about $ 150 million, ”Xia wrote on his Twitter account.

On the evening of December 4, PeckShield recorded an abnormal number of withdrawals from BitMart. Among the tokens that were withdrawn from the trading platform were “meme” tokens, including Shiba Inu, as well as the USDC stablecoin.

Recall that earlier hackers stole about $ 120 million in bitcoins and ether from the decentralized financial (DeFi) platform Badger, which allows users to borrow and lend and speculate on fluctuations in cryptocurrency prices.

Cyberattack Electric Utilities Lost All Data in 25 Years

Published

on

All indications are that the company has fallen victim to ransomware.

Colorado’s Delta-Montrose Electric Association (DMEA) is painfully recovering from a devastating cyberattack that destroyed all of its data over the past 25 years. An attack last month forced the company to shut down 90% of its internal computer systems.

A new notice sent out by DMEA to its customers this week says the company will begin accepting payments through the SmartHub platform and other payment terminals by December 6th. The company hopes to restore billing on December 6-10, so customers should expect an influx of electricity bills. At the same time, DMEA noted that it will not turn off services for non-payment and will not impose fines until January 31, 2022.

Employees of the company began to notice that something was wrong on November 7, and after a while almost the entire computer network of DMEA was turned off. The attack affected all support systems, payment processing tools, billing platforms and other tools provided to customers. According to the company, the hackers attacked certain segments of the internal network and damaged documents, tables and forms, indicating a ransomware attack.

Telephone systems and e-mail were also affected, but power plants and fiber-optic networks were not affected. The personal data of DMEA customers or employees has not been compromised.

DMEA has hired cybersecurity experts to investigate the incident, but is still struggling to rebuild the network.

“We are currently working with limited functionality and are focused on completing investigations and restoring services as efficiently, cost-effectively and securely as possible. We strive to restore our network and get back to normal operations, but this will take time and requires a phased approach, ”the company said.

Hundreds of malicious Tor nodes are used to de-anonymize users

Published

on

Malicious servers were added to the Tor network on an ongoing basis, and there were hundreds of them.

Since at least 2017, a mysterious attacker (or group), tracked by cybersecurity experts as KAX17, has been adding malicious servers to the Tor network, acting as entry, intermediary, and exit nodes. How thinks a security researcher using the pseudonym Nusenu, the campaign aimed to de-anonymize users.

Nusenu, which itself is the Tor node operator, discovered malicious activity in 2019, but says KAX17 has been in effect since at least 2017. According to Nusenu, malicious servers with no contact information were added to the Tor network on an ongoing basis, with hundreds of them. At its peak, the network included over 900 malicious servers.

In general, servers added to the Tor network must contain contact information (such as an email address) so that Tor administrators or law enforcement agencies can contact node operators in the event of misconfiguration or reports of abuse. Despite this rule, servers without contact information are often added to the network, mainly to maintain their numbers.

KAX17 servers are located in data centers around the world and are mostly configured as exit and intermediary nodes, with only a small number of them operating as exit nodes. As Nusenu notes, this is strange enough, since most attackers who manage malicious nodes configure them as exit nodes, which allows them to modify the traffic. For example, the BTCMITM20 group managed a network of thousands of malicious exit nodes to attack users visiting cryptocurrency-related sites.

According to the researcher, KAX17 collects information about users connecting to the Tor network, and then determines their routes. Nusenu reported its findings to the Tor Project last year, and the servers were removed from the network in October 2020. Soon after, another group of exit nodes appeared in Tor with no contact information, but whether it was associated with KAX17 is unclear.

In October and November 2021, the Tor Project also removed hundreds of KAX17 servers. Neither Nusenu nor the Tor Project have speculated yet on who is behind KAX17.
