A group of academics from the University of California and Tsinghua University has uncovered a series of critical security flaws that could lead to a revival of DNS cache poisoning attacks. Dubbed " SAD DNS attack " (short for Side-channel AttackeD DNS), the technique makes it possible for a malicious actor to carry out an off-path attack, rerouting any traffic originally destined to a specific domain to a server under their control, thereby allowing them to eavesdrop and tamper with the communications. "This represents an important milestone — the first weaponizable network side channel attack that has serious security impacts," the researchers said. "The attack allows an off-path attacker to inject a malicious DNS record into a DNS cache." Tracked as CVE-2020-25705, the findings were presented at the ACM Conference on Computer, and Communications Security (CCS '20) held this week. The flaw affects operating systems Linux 3.18-5.10, Windows Serv...

A hackers-for-hire operation has been discovered using a strain of previously undocumented malware to target South Asian financial institutions and global entertainment companies. Dubbed " CostaRicto " by Blackberry researchers, the campaign appears to be the handiwork of APT mercenaries who possess bespoke malware tooling and complex VPN proxy and SSH tunneling capabilities. "CostaRicto targets are scattered across different countries in Europe, Americas, Asia, Australia and Africa, but the biggest concentration appears to be in South Asia (especially India, Bangladesh and Singapore and China), suggesting that the threat actor could be based in that region, but working on a wide range of commissions from diverse clients," the researchers said. The modus operandi in itself is quite straight-forward. Upon gaining an initial foothold in the target's environment via stolen credentials, the attacker proceeds to set up an SSH tunnel to download a backdoor and a p...

Cybersecurity researchers today disclosed a new kind of modular backdoor that targets point-of-sale (POS) restaurant management software from Oracle in an attempt to pilfer sensitive payment information stored in the devices. The backdoor — dubbed "ModPipe" — impacts Oracle MICROS Restaurant Enterprise Series (RES) 3700 POS systems, a widely used software suite in restaurants and hospitality establishments to efficiently handle POS, inventory, and labor management. A majority of the identified targets are primarily located in the US. "What makes the backdoor distinctive are its downloadable modules and their capabilities, as it contains a custom algorithm designed to gather RES 3700 POS database passwords by decrypting them from Windows registry values," ESET researchers said in an analysis . "Exfiltrated credentials allow ModPipe's operators access to database contents, including various definitions and configuration, status tables and information ab...

If organizations want to get serious about software security, they need to empower their engineers to play a defensive role against cyberattacks as they craft their code. The problem is, developers haven't had the most inspiring introduction to security training over the years, and anything that can be done to make their experience more engaging, productive, and fun is going to be a powerful motivator in helping them gain valuable secure coding skills. And after dedicating precious time to mastering new abilities that can help beat attackers at their own game, the opportunity to test these new powers is not easily found in a safe environment. So, what is a battle-hardened, security-aware engineer to do? A new feature released on the Secure Code Warrior platform, named ' Missions ,' is a challenge category that elevates users from the recall of learned security knowledge to the application of it in a real-world simulation environment. This scaffolded, microlearning app...

Google has patched two more zero-day flaws in the Chrome web browser for desktop, making it the fourth and fifth actively exploited vulnerabilities addressed by the search giant in recent weeks. The company released  86.0.4240.198  for Windows, Mac, and Linux, which it said will be rolling out over the coming days/weeks to all users. Tracked as CVE-2020-16013 and CVE-2020-16017, the flaws were discovered and reported to Google by "anonymous" sources, unlike previous cases, which were uncovered by the company's Project Zero elite security team. Google acknowledged that exploits for both the vulnerabilities exist in the wild but stopped short of sharing more specifics to allow a majority of users to install the fixes. According to the release notes, the two flaws are: CVE-2020-16013:  An "inappropriate implementation" of its V8 JavaScript rendering engine was reported on November 9. CVE-2020-16017:  An  use-after-free  memory corruption issue in Chro...

A wave of cyberattacks against retailers running the Magento 1.x e-commerce platform earlier this September has been attributed to one single group, according to the latest research. "This group has carried out a large number of diverse Magecart attacks that often compromise large numbers of websites at once through supply chain attacks, such as the Adverline incident , or through the use of exploits such as in the September Magento 1 compromises," RiskIQ said in an analysis published today. Collectively called Cardbleed , the attacks targeted at least 2,806 online storefronts running Magento 1.x, which reached end-of-life as of June 30, 2020. Injecting e-skimmers on shopping websites to steal credit card details is a tried-and-tested modus operandi of Magecart, a consortium of different hacker groups who target online shopping cart systems. These virtual credit card skimmers, also known as formjacking attacks , are typically JavaScript code that the operators stealth...
