Google and Amazon overtake Apple as most imitated brands for phishing in Q2 2020

blog.checkpoint.com/2020/08/04/google-and-amazon-overtake-apple-as-most-imitated-brands-for-phishing-in-q2-2020/ When the career criminal Willie Sutton was asked by a reporter why he robbed so many banks, he reportedly answered: Because thats where the money is. The same logic applies to the question, Why are there so many phishing attacks? Simply because they work, again and again. Its estimated that phishing is the starting point of over 90% of all attempted cyber-attacks, and Verizons 2019 Data Breach Investigations Report showed that nearly one-third (32%) of actual data breaches involved phishing activity. Whats more, phishing was present in 78% of cyber-espionage incidents and the installation and use of backdoors to networks.

Code-Signing: How Malware Gets a Free Pass

www.gdatasoftware.com/blog/how-malware-gets-a-free-pass In an ideal world, something that is signed cannot not be altered. A signature implies that the signed item is trustworthy and unaltered. When it comes to signed files, things look a bit different: A signature does not always mean that everything is in order. Digitally signing a software – also referred to as code signing – is intended to certify a softwares authenticity. It is a method that provides a sense of assurance to the users that the software they are using is untampered with and true to its original design. In January 2019, Virustotal[1], together with Microsoft, disclosed a vulnerability involving digitally signed Microsoft Installer files(.MSI). Researchers had found out that the validity of a digitally signed MSI file will remain intact even after appending additional content to the end of the file.

Do You Have Enough Cloud Security? Use CIS Controls to Assess Yourself

blog.paloaltonetworks.com/2020/08/cloud-cis-controls/ Clients often ask me, How do I know if I have enough security in the cloud? This is a great question because it shows a willingness to learn. The truth is that there is no right answer. However, a simple place to begin is the basics. You should be sure youre covering the basics well and tracking them closely. This is why I am a huge fan of standards. While they are not the be-all and end-all for security, they give you an excellent place to start.

6 Ransomware Trends You Should Watch for in 2020

The security landscape is constantly changing with emerging technology and new threats. By discovering and reporting vulnerabilities to Microsoft through Coordinated Vulnerability Disclosure (CVD), security researchers have continued to help us secure millions of customers.

Internet Choke Points: Concentration of Authoritative Name Servers

isc.sans.edu/forums/diary/Internet+Choke+Points+Concentration+of+Authoritative+Name+Servers/26428/ A utopian vision of the Internet often describes it as a distributed partnership of equals giving everybody the ability to publish and discover information worldwide. This open, democratic Internet is often little more than an imaginary legacy construct that may have existed at some time in the distant past, if ever. Reality: Today, the Internet is governed by a few large entities. Diverse interconnectivity and content distribution were also supposed to make the Internet more robust. But as it has been shown over and over again, a simple misconfiguration at a single significant player will cause large parts of the network to disappear.

Iranian hacker group becomes first known APT to weaponize DNS-over-HTTPS (DoH)

www.zdnet.com/article/iranian-hacker-group-becomes-first-known-apt-to-weaponize-dns-over-https-doh/ An Iranian hacking group known as Oilrig has become the first publicly known threat actor to incorporate the DNS-over-HTTPS (DoH) protocol in its attacks. Speaking in a webinar last week, Vincente Diaz, a malware analyst for antivirus maker Kaspersky, said the change happened in May this year when Oilrig added a new tool to its hacking arsenal.. According to Diaz, Oilrig operators began using a new utility called DNSExfiltrator as part of their intrusions into hacked networks.

Tietoturvaa vaivannut sama päänsärky jo 30 vuotta ei mikään tuntematon uhka

www.tivi.fi/uutiset/tv/30502d08-b6a4-4dd2-95c4-097d149a23d5 Kiristyshaittaohjelmat ovat vaivanneet internetiä kolmen vuosikymmenen ajan, joten ne eivät todellakaan ole mikään eilispäivän uhka. Tästä huolimatta kaikenkokoisissa yrityksissä väki tuntuu olevan aina yhtä yllättynyt siitä, että tunkeutujat ovat onnistuneet pääsemään järjestelmiin ja verkkoihin. Lopulta uhreille jää vain kaksi vaihtoehtoa: joko rakentaa kriittiset it-järjestelmät alusta asti uudelleen tai maksaa roistoille lunnaat datan salauksen purkamiseksi. Aiheesta myös:

WastedLockers techniques point to a familiar heritage

news.sophos.com/en-us/2020/08/04/wastedlocker-techniques-point-to-a-familiar-heritage/ WastedLockers evades detection by performing most operations in memory, and shares several characteristics with a more well known ransomware family. Its a lot easier to change a ransomwares appearance (or obfuscate its code) than to change its underlying goals or behavior. After all, ransomware must necessarily reveal its intent when it strikes. But there are behavioral traits that ransomware routinely exhibits that security software can use to decide whether the program is malicious. Some traits such as the successive encryption of documents are hard for attackers to change.

Vulnerable perimeter devices: a huge attack surface

www.bleepingcomputer.com/news/security/vulnerable-perimeter-devices-a-huge-attack-surface/ With the increase of critical gateway devices deployed to support off-premise work, companies across the world have to adapt to a new threat landscape where perimeter and remote access devices are now in the first line. Companies lack visibility into the growing network of internet-connected services and devices that support the new work paradigm; and the avalanche of vulnerabilities reported for edge devices make tackling the new security challenge even more difficult.
