Reimagine Hybrid Work: Same CyberSec in Office and at Home

Reimagine Hybrid Work: Same CyberSec in Office and at Home

Jun 17, 2022
It was first the pandemic that changed the usual state of work - before, it was commuting, working in the office & coming home for most corporate employees. Then, when we had to adapt to the self-isolation rules, the work moved to home offices, which completely changed the workflow for many businesses. As the pandemic went down, we realized success never relied on where the work was done. Whether your office is your kitchen, your bedroom, a nearby cafe, or your actual workplace in an office building, it all comes down to the fact that job success has nothing to do with your location.  The role of the office in the hybrid era is also changing - according to the research conducted by  PwC , it now serves the purpose of collaborating with team members and building relationships. From an employee's side, it sounds pretty logical and obvious.  However, if we look at hybrid work with the eyes of an employer, things get complicated. How does one make sure corporate devices & da
SAD DNS — New Flaws Re-Enable DNS Cache Poisoning Attacks

SAD DNS — New Flaws Re-Enable DNS Cache Poisoning Attacks

Nov 13, 2020
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

'Karkoff' Is the New 'DNSpionage' With Selective Targeting Strategy

Apr 24, 2019
The cybercriminal group behind the infamous DNSpionage malware campaign has been found running a new sophisticated operation that infects selected victims with a new variant of the DNSpionage malware. First uncovered in November last year, the DNSpionage attacks used compromised sites and crafted malicious documents to infect victims' computers with DNSpionage —a custom remote administrative tool that uses HTTP and DNS communication to communicate with the attacker-controlled command and control server. According to a new report published by Cisco's Talos threat research team, the group has adopted some new tactics, techniques and procedures to improve the efficacy of their operations, making their cyber attacks more targeted, organised and sophisticated in nature. Unlike previous campaigns, attackers have now started performing reconnaissance on its victims before infecting them with a new piece of malware, dubbed Karkoff , allowing them to selectively choose which t

What's the Right EDR for You?

What's the Right EDR for You?

May 10, 2024Endpoint Security / Threat Detection
A guide to finding the right endpoint detection and response (EDR) solution for your business' unique needs. Cybersecurity has become an ongoing battle between hackers and small- and mid-sized businesses. Though perimeter security measures like antivirus and firewalls have traditionally served as the frontlines of defense, the battleground has shifted to endpoints. This is why endpoint detection and response (EDR) solutions now serve as critical weapons in the fight, empowering you and your organization to detect known and unknown threats, respond to them quickly, and extend the cybersecurity fight across all phases of an attack.  With the growing need to defend your devices from today's cyber threats, however, choosing the right EDR solution can be a daunting task. There are so many options and features to choose from, and not all EDR solutions are made with everyday businesses and IT teams in mind. So how do you pick the best solution for your needs? Why EDR Is a Must Because of
GhostDNS: New DNS Changer Botnet Hijacked Over 100,000 Routers

GhostDNS: New DNS Changer Botnet Hijacked Over 100,000 Routers

Oct 01, 2018
Chinese cybersecurity researchers have uncovered a widespread, ongoing malware campaign that has already hijacked over 100,000 home routers and modified their DNS settings to hack users with malicious web pages—especially if they visit banking sites—and steal their login credentials. Dubbed GhostDNS , the campaign has many similarities with the infamous DNSChanger malware that works by changing DNS server settings on an infected device, allowing attackers to route the users' internet traffic through malicious servers and steal sensitive data. According to a new report from cybersecurity firm Qihoo 360's NetLab, just like the regular DNSChanger campaign, GhostDNS scans for the IP addresses for routers that use weak or no password at all, accesses the routers' settings, and then changes the router's default DNS address to the one controlled by the attackers. GhostDNS System: List of Modules and Sub-Modules The GhostDNS system mainly includes four modules:
New Point-of-Sale Malware Steals Credit Card Data via DNS Queries

New Point-of-Sale Malware Steals Credit Card Data via DNS Queries

Feb 09, 2018
Cybercriminals are becoming more adept, innovative, and stealthy with each passing day. They are now adopting more clandestine techniques that come with limitless attack vectors and are harder to detect. A new strain of malware has now been discovered that relies on a unique technique to steal payment card information from point-of-sale (PoS) systems. Since the new POS malware relies upon User Datagram Protocol (UDP) DNS traffic for the exfiltration of credit card information, security researchers at Forcepoint Labs, who have uncovered the malware, dubbed it UDPoS . Yes, UDPoS uses Domain Name System (DNS) queries to exfiltrate stolen data, instead of HTTP that has been used by most POS malware in the past. This malware is also thought to be first of its kind. Besides using 'unusual' DNS requests to exfiltrate data, the UDPoS malware disguises itself as an update from LogMeIn —a legitimate remote desktop control service used to manage computers and other systems remo

Critical Flaw in All Blizzard Games Could Let Hackers Hijack Millions of PCs

Jan 23, 2018
A Google security researcher has discovered a severe vulnerability in Blizzard games that could allow remote attackers to run malicious code on gamers' computers. Played every month by half a billion users—World of Warcraft, Overwatch, Diablo III, Hearthstone and Starcraft II are popular online games created by Blizzard Entertainment . To play Blizzard games online using web browsers, users need to install a game client application, called ' Blizzard Update Agent ,' onto their systems that run JSON-RPC server over HTTP protocol on port 1120, and " accepts commands to install, uninstall, change settings, update and other maintenance related options. " Google's Project Zero team researcher Tavis Ormandy discovered that the Blizzard Update Agent is vulnerable to a hacking technique called the " DNS Rebinding " attack that allows any website to act as a bridge between the external server and your localhost. Just last week, Ormandy revealed a simi

Hacker Hijacks CoinHive's DNS to Mine Cryptocurrency Using Thousands of Websites

Oct 25, 2017
When yesterday I was reporting about the sudden outbreak of another global ransomware attack ' Bad Rabbit ,' I thought what could be worse than this? Then late last night I got my answer with a notification that Coinhive has been hacked — a popular browser-based service that offers website owners to embed a JavaScript to utilise their site visitors' CPUs power to mine the Monero cryptocurrency for monetisation. Reportedly an unknown hacker managed to hijack Coinhive's CloudFlare account that allowed him/her to modify its DNS servers and replace Coinhive's official JavaScript code embedded into thousands of websites with a malicious version. https://coin-hive[.]com/lib/coinhive.min.js Hacker Reused Leaked Password from 2014 Data Breach Apparently, hacker reused an old password to access Coinhive's CloudFlare account that was leaked in the Kickstarter data breach in 2014.
