Firefox zero-day was used in attack against Coinbase employees, not its users

www.zdnet.com/article/firefox-zero-day-was-used-in-attack-against-coinbase-employees-not-its-users/ There were actually two zero-days — not one — combined into an exploit used in a spear-phishing attempt. Other cryptocurrency organizations were also targeted. A recent Firefox zero-day that has made headlines across the tech news world this week was actually used in attacks against Coinbase employees, and not the company’s users, ZDNet has learned.

Cryptocurrency Mining Botnet Arrives Through ADB and Spreads Through SSH

blog.trendmicro.com/trendlabs-security-intelligence/cryptocurrency-mining-botnet-arrives-through-adb-and-spreads-through-ssh/ We observed a new cryptocurrency mining botnet that arrives via open ADB (Android Debug Bridge) ports and can spread via SSH. This attack takes advantage of the way open ADB ports dont have authentication by default, similar to the Satori botnet variant we previously reported. This botnets design allows it to spread from the infected host to any system that has had a previous SSH connection with the host. The use of ADB makes Android-based devices susceptible to the malware. We detected activity from this botnet in 21 different countries, with the highest percentage found in South Korea.

Cisco critical-flaw warning: These two bugs in our data-center gear need patching now

www.zdnet.com/article/cisco-critical-flaw-warning-these-two-bugs-in-our-data-center-gear-need-patching-now/ Cisco is warning enterprise admins to install security updates for two critical flaws. Networking giant Cisco has disclosed two critical vulnerabilities affecting core equipment in the data center that could give determined attackers an avenue to break into networks. Cisco’s Digital Network Architecture (DNA) Center appliance has once again been found to be vulnerable to an authentication bypass, which could allow an “adjacent” attacker to skip authentication and cause damage to an organization’s critical internal services. The flaw, tagged as CVE-2019-1848, is because Cisco didn’t sufficiently restrict access to ports used to operate the system. The vulnerability would allow an attacker to connect an unauthorized device to the network. See also:

Google takes the PIS out of advertising: New algo securely analyzes shared encrypted data sets without leaking contents

www.theregister.co.uk/2019/06/19/google_pis_encryption/ Google on Wednesday released source code for a project called Private Join and Compute that allows two parties to analyze and compare shared sets of data without revealing the contents of each set to the other party. This is useful if you want to see how your private encrypted data set of, say, ad-clicks-to-sales conversion rates, correlates to someone else’s encrypted conversion rate data set without disclosing the actual numbers to either side. This particular technique is a type of secure multiparty computation that builds upon a cryptographic protocol called Private Set-Intersection (PSI). Google employs this approach in a Chrome extension called Password Checkup that lets users test logins and passwords against a dataset of compromised credentials without revealing the query to the internet goliath.

Check Points Threat Emulation Stops Large-Scale Phishing Campaign in Germany

blog.checkpoint.com/2019/06/19/sandblast-agent-phishing-germany-campaign-security-hack-ransomware/ During the first week of June 2019, Check Point researchers encountered a new, large-scale phishing campaign targeting German companies across all industries. The hackers goal was to install Remcos a remote control tool on the victims computers. The attackers initially sent fake emails that appeared to be from several legitimate companies across Germany. These emails contained invoices or urgent order attachments which were actually Remcos archives attempting to connect with the attackers command and control (C&C) server. See also

Modular Plurox Malware Is a Wormable Backdoor Cryptominer

www.bleepingcomputer.com/news/security/modular-plurox-malware-is-a-wormable-backdoor-cryptominer/ A new modular backdoor malware strain capable of mining cryptocurrencies and of spreading to other machines on the local network with the help of SMB and UPnP plugins has been detected by Kaspersky security researchers. The backdoor malware named Plurox was discovered in February and it seems to be still in its testing phase given that it’s source code and the communication channels it uses to contact its command-and-control (C&C) server are not yet encrypted in any way.

Feds: Cyberattack on NASAs JPL Threatened Mission-Control Data

threatpost.com/feds-hackers-mission-control-data-nasa-jpl/145842/ Rampant security-operations bungling allowed cyberattackers to infiltrate JPLs network, which carries human mission data.. NASAs Jet Propulsion Laboratory (JPL) may know how to send delicate equipment to Mars, but basic cybersecurity best practices appear to pose an issue for it. A comprehensive federal review has detailed an April 2018 security incident that compromised mission systems stemming from multiple IT security-control weaknesses exposing NASA systems and data. The review, released Tuesday and carried out by the U.S. Office of the Inspector General, said that the weaknesses reduce JPLs ability to prevent, detect and mitigate attacks targeting its systems and networks.. Specifically, poor practices when it comes to network segmentation and third parties were source of a cyberattack in April 2018, OIG said. See also oig.nasa.gov/docs/IG-19-022.pdf

Cryptominer Uses Cron To Reinfect Linux Host After Removal

www.bleepingcomputer.com/news/security/cryptominer-uses-cron-to-reinfect-linux-host-after-removal/ A cryptomining dropper malware has been spotted by security researchers while gaining persistence on Linux hosts by adding cron jobs to reinfect the compromised machines after being removed. The malware was initially discovered on a web server with a maxed out CPU by a malicious process, a sure sign of a host infected with cryptomining malware configured to use all available computing resources. As Sucuri’s security analyst Luke Leal found after taking a closer look, the cryptominer is downloaded by attackers using a Bash script dropped on the server via an unknown method most probably after exploiting an unpatched vulnerability, brute forcing their way in, or by phishing the admin credentials.

Russian APT hacked Iranian APT’s infrastructure back in 2017

www.zdnet.com/article/russian-apt-hacked-iranian-apts-infrastructure-back-in-2017/ Turla APT hacked Iran’s APT34 group and used its C&C servers to re-infect APT34 victims with its own malware. As fellow ZDNet writer Andrada Fiscutean once wrote in the fall of 2017: “Spies hack. But the best spies hack other spies.”. That story revolved around a Virus Bulletin 2017 talk detailing several mysterious cases where APTs (advanced persistent threats, a technical term used to describe government-backed hacking units) appeared to had compromised the infrastructure of other APTs, either by accident, or intentionally. While investigating this campaign for its own report, Symantec said it found evidence that sometime in November 2017, the Turla APT (which Symantec calls Waterbug) had hacked into the server infrastructure of an Iranian APT known as APT34 (also known as Oilrig or Crambus).
