    APT29: SVR cyberspies used iOS zero-day in recent phishing campaign
    APT29 took control over the Constant Contact account and used it to send around 3, 000 booby-trapped emails to more than 150 organizations across 24 countries. In the vast majority of emails, the hackers sent links to victims that redirected them to websites that used JavaScript code to drop a malicious ISO image file on their computers. What was notable of the recent attacks was that in particular cases, the hackers filtered incoming users and directed iOS users to a special page where they deployed a Safari iOS zero-day bug to infect victims’

    M1racles – Covert channel in Apple’s M1 is mostly harmless, but it sure is interesting
    Technically, it’s a vulnerability, but there’s not much an attacker can do with it. The channel can bridge processes running as different users and under different privilege levels. These characteristics allow for the apps to exchange data in a way that can’t be detectedor at least without specialized equipment.

    Google Suddenly Flips The Password Privacy Switch For Billions Of Users
    Google has suddenly started rolling out two-factor authentication
    (2FA) automatic enrollment to users. Google keeps track of your activity across all services such as search, YouTube and the Google assistant. Seeing as just about everyone is logged in all the time, that presents a massive security and privacy problem. Do you really want a partner, friend, work colleague or worse to be able to see what you search for, where you visit online, and the videos you watch?

    To that effect, the company intends to register all compatible devices that are operational in the U.S. into an ambitious location-tracking system called Sidewalk as it prepares to roll out the shared mesh network in the country.

    Denmark’s foreign secret service allowed the US National Security Agency to tap into a crucial internet and telecommunications hub in Denmark and spy on the communications of European politicians, a joint investigation by some of Europe’s biggest news agencies revealed on Sunday. The covert spying operation, called Operation Dunhammer, took place between 2012 and 2014, based on a secret partnership signed by the two agencies.

    Swedish Health Agency shuts down SmiNet after hacking attempts
    The Swedish Public Health Agency (Folkhälsomyndigheten) has shut down SmiNet, the country’s infectious diseases database, on Thursday after it was targeted in several hacking attempts. SmiNet, which is also used to store electronic reports with statistics on COVID-19 infections, was shut down on Thursday to investigate the attacks and was brought back online on Friday evening. While no evidence of unauthorized parties accessing sensitive information was found so far, the investigation will take at least a few more days until the reporting process will be restarted.

    US Army tells remote workers to switch off their IoT devices (and then withdraws advice)
    The US Army appears to have made a strategic withdrawal from advice it issued to remote workers last week about their use of smart IoT devices. The message from the Army’s Chief Information Officer Dr Raj Iyer on how to protect and safeguard Department of Defense data by making more efforts to mitigate data leaks was clear: Remove all IoT devices, with listening functions, from the work area. Furthermore, the initial announcement of the policy’s existence has also been removed although a copy remains in a Google cache.

    Cybercriminals Target Companies With New ‘Epsilon Red’ Ransomware

    A new piece of ransomware named Epsilon Red has been used to target at least one organization in the United States, and its operators have apparently already made a significant profit.

    Cybersecurity firm Sophos reported last week that Epsilon Red operators have been spotted targeting a US-based company in the hospitality sector. The cryptocurrency address provided by the cybercriminals shows a bitcoin transaction for an amount worth roughly $210,000, which seems to indicate that at least one victim has agreed to pay the ransom demanded by the cybercriminals.

    Sophos researchers noticed that the ransom note dropped by Epsilon Red is similar to the one displayed by the REvil ransomware, but Epsilon Red’s ransom note is better written — it does not contain some of the grammar errors in the REvil note.

    Interpol Says 585 People Arrested in APAC Operation Against Cyber-Enabled Crime

    Interpol revealed last week that specialized law enforcement officers in the Asia-Pacific (APAC) region intercepted more than $83 million in fraudulent money transfers as part of a six-month coordinated effort aimed at cyber-enabled financial crime.

    Codenamed HAECHI-I, the operation mainly targeted five types of online financial crime: investment fraud, money laundering (from illegal online gaming), online sextortion, romance scams, and voice phishing (vishing).

    The operation resulted in over 1,600 bank accounts worldwide being frozen as part of roughly 1,400 investigations opened between September 2020 and March 2021, with a total of 892 cases being solved.

    As part of the effort, authorities arrested a total of 585 individuals, Interpol says.
