Back when the internet consisted of a handful of computers networked together across a few research institutions, nobody could have imagined that it would one day form the backbone of a new digital way of life. And that probably explains why none of the researchers who thought up its core technologies — things like packet switching and TCP/IP — gave much consideration to the need to secure the data passing through it. But by 1989, hackers like Robert Morris had already spotted the security weaknesses of the fledgling global network and started to exploit them. And that was just the beginning. Today, network administrators and individual internet users spend significant amounts of time and money trying to keep their data safe from prying eyes. The de-facto tool most people use for that purpose is a VPN. It's a software encryption solution that prevents anyone from accessing data traversing the public internet other than its intended recipient. And VPNs make up a data privacy mark...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  two flaws to its  Known Exploited Vulnerabilities Catalog , citing evidence of active exploitation. The two high-severity issues relate to weaknesses in Zimbra Collaboration, both of which could be chained to achieve unauthenticated remote code execution on affected email servers - CVE-2022-27925  (CVSS score: 7.2) - Remote code execution (RCE) through mboximport from authenticated user (fixed in  versions  8.8.15 Patch 31 and 9.0.0 Patch 24 released in March) CVE-2022-37042  - Authentication bypass in MailboxImportServlet (fixed in  versions  8.8.15 Patch 33 and 9.0.0 Patch 26 released in August) "If you are running a Zimbra version that is older than Zimbra 8.8.15 patch 33 or Zimbra 9.0.0 patch 26 you should update to the latest patch as soon as possible," Zimbra  warned  earlier this week. CISA has not shared any information on the attac...

A trio of offshoots from the notorious Conti cybercrime cartel have resorted to the technique of call back phishing as an initial access vector to breach targeted networks. "Three autonomous threat groups have since adopted and independently developed their own targeted phishing tactics derived from the call back phishing methodology," cybersecurity firm AdvIntel  said  in a Wednesday report. These targeted campaigns "substantially increased" attacks against entities in finance, technology, legal, and insurance sectors, the company added. The actors in question include Silent Ransom, Quantum, and Roy/Zeon, all of which split from Conti after the ransomware-as-a-service (RaaS) cartel  orchestrated its shutdown  in May 2022 following its public support for Russia in the ongoing Russo-Ukrainian conflict. The advanced social engineering tactic, also called  BazaCall  (aka BazarCall), came under the spotlight in 2020/2021 when it was put to use by operator...

Networking equipment major Cisco on Wednesday confirmed it was the victim of a cyberattack on May 24, 2022 after the attackers got hold of an employee's personal Google account that contained passwords synced from their web browser. "Initial access to the Cisco VPN was achieved via the successful compromise of a Cisco employee's personal Google account," Cisco Talos  said  in a detailed write-up. "The user had enabled password syncing via Google Chrome and had stored their Cisco credentials in their browser, enabling that information to synchronize to their Google account." The disclosure comes as cybercriminal actors associated with the Yanluowang ransomware gang  published a list of files  from the breach to their data leak site on August 10. The exfiltrated information, according to Talos, included the contents of a Box cloud storage folder that was associated with the compromised employee's account and is not believed to have included any valuabl...

Threat actors associated with the Cuba ransomware have been linked to previously undocumented tactics, techniques and procedures (TTPs), including a new remote access trojan called ROMCOM RAT on compromised systems. The  new findings  come from Palo Alto Networks' Unit 42 threat intelligence team, which is tracking the double extortion ransomware group under the  constellation-themed moniker   Tropical Scorpius . Cuba ransomware (aka  COLDDRAW ), which was first detected in December 2019, reemerged on the threat landscape in November 2021 and has been attributed to attacks against 60 entities in five critical infrastructure sectors, amassing at least $43.9 million in ransom payments. Of the 60 victims listed on its data leak site, 40 are located in the U.S., indicating a not as global distribution of targeted organizations as other ransomware gangs. "Cuba ransomware is distributed through Hancitor malware, a loader known for dropping or executing stealers,...

Password security is only as strong as the password itself. Unfortunately, we are often reminded of the danger of weak, reused, and compromised passwords with major cybersecurity breaches that start with stolen credentials. For example, in May 2022, the popular wedding planning site, Zola, was the victim of a significant cybersecurity breach where hackers used an attack known as  credential stuffing . It resulted in fraudulent activity tied to customer accounts. Let's look at the Zola breach and why it emphasizes the need for organizations to bolster their password security and protect against various types of password attacks. What happened with the Zola attack? Instead of going after Zola's core business-critical infrastructure, hackers went after customer accounts with the May attack. Attackers used an age-old technique called  credential stuffing  to compromise several Zola customer accounts. With access to the compromised accounts, they attempted to purchase gift ...

Cybersecurity researchers have disclosed multiple severe security vulnerabilities asset management platform  Device42  that, if successfully exploited, could enable a malicious actor to seize control of affected systems. "By exploiting these issues, an attacker could impersonate other users, obtain admin-level access in the application (by leaking session with an  LFI ) or obtain full access to the appliance files and database (through remote code execution)," Bitdefender  said  in a Wednesday report. Even more concerningly, an adversary with any level of access within the host network could daisy-chain three of the flaws to bypass authentication protections and achieve remote code execution with the highest privileges. The issues in question are listed below - CVE-2022-1399  - Remote Code Execution in scheduled tasks component CVE-2022-1400  - Hard-coded encryption key IV in Exago WebReportsApi.dll CVE 2022-1401  - Insufficient validati...
