If there’s somethin’ stored in a secure enclave, who ya gonna call? Membuster!

www.theregister.co.uk/2019/12/05/membuster_secure_enclave/ Computer scientists from UC Berkeley, Texas A&M, and semiconductor biz SK Hynix have found a way to defeat secure enclave protections by observing memory requests from a CPU to off-chip DRAM through the memory bus.

VCs find exciting new way to blow $1m: Wire it directly to hackers after getting spoofed

www.theregister.co.uk/2019/12/05/vcs_tricked_mitm/ A group of hackers used a compromised email account to steal a start-up’s $1m venture capital payment. The incident response team at security house Check Point says it was called in to investigate the case of money that a Chinese VC firm had reported missing after it was supposedly sent to a startup in Israel. It was believed that the attack was down to a compromised email account that had been used to re-route the payment to an account controlled by the attacker, a rather cut-and-dry business email compromise (BEC) operation.

Tricky VPN-busting bug lurks in iOS, Android, Linux distros, macOS, FreeBSD, OpenBSD, say university eggheads

www.theregister.co.uk/2019/12/06/vpnbusting_bug_spotted/ A bug in the way Unix-flavored systems handle TCP connections could put VPN users at risk of having their encrypted traffic hijacked, it is claimed. The University of New Mexico team of William Tolley, Beau Kujath, and Jedidiah Crandall this week said they’ve discovered CVE-2019-14899, a security weakness they report to be present in “most” Linux distros, along with Android, iOS, macOS, FreeBSD, and OpenBSD. The upshot is, if exploited, encrypted VPN traffic can be potentially hijacked and disrupted by miscreants on the network. To pull off the attack, the US-based posse says, a hacker would need to be “network adjacent” to their target, or control an access point on the victim’s local network. Once the victim connected to their VPN, the spy would be able to, for one thing, tamper with the TCP stream to do things like inject packets into the stream. This could be potentially used, we imagine, to force malicious JavaScript into webpages being visited via the VPN, for example. Read also:

FBI recommends that you keep your IoT devices on a separate network

www.zdnet.com/article/fbi-recommends-that-you-keep-your-iot-devices-on-a-separate-network/ The FBI also recommends changing factory-set (default) passwords and not allowing an IoT device’s accompanying mobile app to gain access to too many smartphone permissions. The FBI says owners of IoT (Internet of Things) devices should isolate this equipment on a separate WiFi network, different from the one they’re using for their primary devices, such as laptops, desktops, or smartphones.

The most copied StackOverflow Java code snippet contains a bug

www.zdnet.com/article/the-most-copied-stackoverflow-java-code-snippet-contains-a-bug/ The most copied StackOverflow Java code snippet of all time contains a bug. The admission comes from the author of the snippet itself, Andreas Lundblad, a Java developer at Palantir, and one of the highest-ranked contributors to StackOverflow, a Q&A website for programming-related topics. Academics found that this code had been copied and embedded in more than 6, 000 GitHub Java projects, more than any other StackOverflow Java snippet.

The “Great Cannon” has been deployed again

cybersecurity.att.com/blogs/labs-research/the-great-cannon-has-been-deployed-again The Great Cannon is a distributed denial of service tool (“DDoS”) that operates by injecting malicious Javascript into pages served from behind the Great Firewall. These scripts, potentially served to millions of users across the internet, hijack the users’ connections to make multiple requests against the targeted site. These requests consume all the resources of the targeted site, making it . The Great Cannon was the subject of intense research after it was used to disrupt access to the website Github.com in 2015. Little has been seen of the Great Cannon since 2015. However, we’ve recently observed new attacks, which are detailed below.

Some Hardware-based Password Managers Have Poor Security

www.bleepingcomputer.com/news/security/some-hardware-based-password-managers-have-poor-security/ Some hardware-based password managers lack proper protections for the sensitive data they store and allow reading it in plain text, even after they’ve been reset. The information was retrieved through physical access to the electronic board inside the device and connecting directly to the flash chips used for storage.

Se on kuin netin hajautettu puhelinluettelo koneille. Dns-osoitteiston puurakenteen solmuja kutsutaan domaineiksi. Juurisolmun alla ovat esimerkiksi.edu, .org, .com, ja suomalainen.fi. Niiden alla ovat organisaatioiden, yritysten ja käyttäjien domainit, joilla voi edelleen olla alidomaineja.

These are the worst hacks, cyberattacks, and data breaches of 2019

www.zdnet.com/article/these-are-the-worst-hacks-cyberattacks-and-data-breaches-of-2019/ A slew of hacks, data breaches, and attacks tainted the cybersecurity landscape in 2019. For the past few years, there has been a constant stream of data breaches that have hit the headlines, ranging from the theft of medical information, account credentials, corporate emails, and internal sensitive enterprise data. When a data breach occurs, companies will usually haul in third-party investigators, notify regulators, promise to do better and give any impacted consumers free credit monitoring — but we’ve reached a stage where you should consider signing up to such services anyway, given how much of our information is now available in data dumps strewn all over the internet. (Consider using Have I Been Pwned to check if you’ve been involved in a breach.)

So far, feds say they have halted more than 600 domestic money mules exceeding the 400 money mules stopped last year. Of these, more than 30 individuals were criminally charged for their roles in receiving victim payments and providing the fraud proceeds to accomplices.
