Small and mediumsized businesses: Big targets for ransomware attacks
www.welivesecurity.com/2020/08/07/small-medium-sized-businesses-big-targets-ransomware-attacks/ Why are SMBs a target for ransomware-wielding gangs and what can they do to protect themselves against cyber-extortion?. While large enterprises may present themselves as more lucrative prey, SMBs are an attractive target due to their lack of resources to defend against such attacks.

Beyond KrØØk: Even more WiFi chips vulnerable to eavesdropping
www.welivesecurity.com/2020/08/06/beyond-kr00k-even-more-wifi-chips-vulnerable-eavesdropping/ At Black Hat USA 2020, ESET researchers delved into details about the KrØØk vulnerability in Wi-Fi chips and revealed that similar bugs affect more chip brands than previously thought. KrØØk (formally CVE-2019-15126) is a vulnerability in Broadcom and Cypress Wi-Fi chips that allows unauthorized decryption of some WPA2-encrypted traffic. Specifically, the bug has led to wireless network data being encrypted with a WPA2 pairwise session key that is all zeros instead of the proper session key that had previously been established in the 4-way handshake. This undesirable state occurs on vulnerable Broadcom and Cypress chips following a Wi-Fi disassociation.
DEF CON: New tool brings back ‘domain fronting’ as ‘domain hiding’
www.zdnet.com/article/def-con-new-tool-brings-back-domain-fronting-as-domain-hiding/ After Amazon and Google stopped supporting the censorship-evading domain fronting technique on their clouds in 2018, new Noctilucent toolkit aims to bring it back in a new form as “domain hiding.”. At the DEF CON 28 security conference this week, a security researcher has released a new tool that can help the makers of sensitive applications evade censorship and bypass firewalls to keep services up inside problematic areas of the globe. Domain fronting is a technique that has been made popular by mobile app developers in the 2010s and has been used to allow apps to bypass censorship attempts in oppressive countries.
Researchers found another way to hack Android cellphones via Bluetooth
www.cyberscoop.com/bluetooth-vulnerability-android-dbappsecurity-black-hat-2020/ Attackers looking to steal sensitive information like contacts, call history, and SMS verification codes from Android devices only need to target Bluetooth protocols, according to new DBAPPSecurity research presented at the 2020 Black Hat conference Wednesday. These exploits, one of which takes advantage of a zero-day vulnerability, could also allow hackers to send fake text messages if manipulated properly, researchers found. The other attack allows researchers to take advantage of an authentication bypass vulnerability, dubbed “BlueRepli.” Would-be attackers can bypass authentication by imitating a device that has previously been connected with a target. Victims do not need to give permission to a device for the exploit to work. Read also:

Attackers don’t need to directly hack into a programmable logic controller (PLC) to wreak havoc on an industrial process: they can target its configuration files and pivot from there.
Käytätkö yhä vanhaa Windowsia? FBI:n varoitus pätee myös Suomessa
www.is.fi/digitoday/tietoturva/art-2000006594380.html Yhdysvaltain liittovaltion poliisi FBI julkaisi varoituksen (pdf) Windows 7 -käyttöjärjestelmästä, joka julkaistiin vuonna 2009. Se lakkasi saamasta tietoturvakorjauksia viime tammikuussa, ellei niistä erikseen makseta. FBI:n varoitus on suunnattu yrityksille, mutta viesti on selvä kaikille Windows 7:n käyttäjille. Käyttöjärjestelmästä pitäisi luopua pikimmiten. FBI sanoo havainneensa, että rikolliset tähtäävät sellaisiin tietokoneisiin joiden käyttöjärjestelmä on saavuttanut elinkaarensa päätepisteen. Ajan myötä Windows 7:stä tulee aina vain haavoittuvampi hyökkäyksille, kun siitä löydetään uusia ja ilman korjausta jääviä haavoittuvuuksia. Lue myös itse varoitus:

Why You Should Stop Sending SMS MessagesEven On Apple iMessage
www.forbes.com/sites/zakdoffman/2020/08/08/apple-iphone-ipad-imessage-security-update-sms-rcs-google-whatsapp-encryption/ SMS is at the other end of the security spectrum, built on an archaic architecture that sits inside the many cellular networks around the world. When you send an SMS, while it might be secure between your phone and your network, once there it can be easily intercepted and collected. Last year I reported on hackers compromising global telcos to collect SMS traffic between targeted senders and recipients. As FireEye warned at the time, “users and organizations must consider the risk of unencrypted data being intercepted several layers upstream in their cellular communication chain.”

Fake e-mail scanner
www.kaspersky.com/blog/phishing-email-scanner/36661/ A detailed look at a phishing site masquerading as an e-mail scanner and its attempts to snag victims. This scam message employs the time-honored trick of victim intimidation. You can see it right in the header, which reads “Virus Alert” followed by three exclamation points. However trifling punctuation may seem, it’s the first thing that should tip off the recipient that something may be wrong. Unnecessary punctuation in a work e-mail is a sign of drama or unprofessionalism. Either way, it’s inappropriate in a notification supposedly intended to convey information about a threat.
