Another new widespread and disastrous SSL/TLS vulnerability has been uncovered that for over a decade left Millions of users of Apple and Android devices vulnerable to man-in-the-middle attacks on encrypted traffic when they visited supposedly 'secured' websites, including the official websites of the White House, FBI and National Security Agency. Dubbed the " FREAK " vulnerability ( CVE-2015-0204 ) - also known as Factoring Attack on RSA-EXPORT Keys - enables hackers or intelligence agencies to force clients to use older, weaker encryption i.e. also known as the export-grade key or 512-bit RSA keys. FREAK vulnerability discovered by security researchers of French Institute for Research in Computer Science and Automation (Inria) and Microsoft, resides in OpenSSL versions 1.01k and earlier, and Apple's Secure Transport. 90s WEAK EXPORT-GRADE ENCRYPTION Back in 1990s, the US government attempted to regulate the export of products utilizing ...

WhatsApp acquisition may have had a negative impact on the reputation of the company, it seems many users are planning to switch the service and a few of them have already done it. In our previous article, we have mentioned that why you should switch from WhatsApp to an encrypted Chat messaging service . Mobile messaging apps often used to deliver sensitive data or used for personal and corporate communications, so the data stored by the service provider should be encrypted end-to-end, which is not yet in the case of WhatsApp. There are many mobile messaging applications like Japan-based  Line , China’s  WeChat , Korea-based  KakaoTalk , and Canada’s  Kik , India-based  Hike  and many more, but they are not end-to-end encrypted messengers. Time is loudly announcing the need to shift to some alternates which provides end-to-end encryption for communication between two devices and respect your Privacy. There are a number of solutions available...

A new variant of Vega ransomware family, dubbed Zeppelin , has recently been spotted in the wild targeting technology and healthcare companies across Europe, the United States, and Canada. However, if you reside in Russia or some other ex-USSR countries like Ukraine, Belorussia, and Kazakhstan, breathe a sigh of relief, as the ransomware terminates its operations if found itself on machines located in these regions. It's notable and interesting because all previous variants of the Vega family, also known as VegaLocker, were primarily targeting Russian speaking users, which indicates Zeppelin is not the work of the same hacking group behind the previous attacks. Since Vega ransomware and its previous variants were offered as a service on underground forums, researchers at BlackBerry Cylance believes either Zeppelin "ended up in the hands of different threat actors" or "redeveloped from bought/stolen/leaked sources." According to a report BlackBerry Cyl...

Microsoft has come up with its most important Patch Tuesday for this year, addressing the recently disclosed critical the FREAK encryption-downgrade attack , and a separate five-year-old vulnerability leveraged by infamous Stuxnet malware to infect Windows operating system. Stuxnet malware , a sophisticated cyber-espionage malware allegedly developed by the US Intelligence and Israeli government together, was specially designed to sabotage the Iranian nuclear facilities a few years ago. First uncovered in 2010, Stuxnet targeted computers by exploiting vulnerabilities in Windows systems. Thankfully, Microsoft has issued a patch to protect its Windows machines that have been left vulnerable to Stuxnet and other similar attacks for the past five years. The fixes are included in MS15-020 which resolves Stuxnet issue. The company has also issued an update that patches the FREAK encryption vulnerability in its SSL/TSL implementation called Secure Channel (Schannel). The fix...

So, How do Hackers compromise a Website? Simply by exploiting the flaws in it, that means they took advantage of the error in the developers’ code. Now, this time the hackers itself has left behind a crucial flaw in its malware code which can be exploited by us to help save our computer systems. Believe me, it’s not an April Fools’ joke! A malicious software program that holds the victims’ computer files hostage by wrapping them with strong encryption until the victim pays a ransom fee to get them decrypted, has a critical flaw in its malware code itself that it leaves the decryption key on the victim’s computer. The Anti-virus firm Symantec examined a sophisticated malware program dubbed as CryptoDefense (Trojan.Cryptodefense) ransomware , which appeared in the end of the last month. CryptoDefense is one of the complex malware programs that include a number of effective techniques, including Tor anonymity tool usage and Bitcoin digital currency to extort money from victims. Cryp...

An 18-month-long analysis of the PYSA ransomware operation has revealed that the cybercrime cartel followed a five-stage software development cycle from August 2020, with the malware authors prioritizing features to improve the efficiency of its workflows. This included a user-friendly tool like a full-text search engine to facilitate the extraction of metadata and enable the threat actors to find and access victim information quickly. "The group is known to carefully research high-value targets before launching its attacks, compromising enterprise systems and forcing organizations to pay large ransoms to restore their data," Swiss cybersecurity company PRODAFT  said  in an exhaustive report published last week. PYSA, short for "Protect Your System, Amigo" and a successor to the Mespinoza ransomware, was first observed in December 2019 and has emerged as the third most prevalent ransomware strain detected during the fourth quarter of 2021. Since September 2020,...

Since past few years, Ransomware has emerged as one of the catastrophic malware programs that lets hacker encrypts all the contents of a victim's hard drive or/and server and demands ransom (typically to be paid in Bitcoin ) in exchange for a key to decrypt it. Until now cyber criminals were targeting computers, smartphones and tablets, but now it appears they are creating ransomware that makes the same impact but for Web Sites – specifically holding files, pages and images of the target website for Ransom. Dubbed Linux.Encoder.1 by Russian antivirus firm Dr.Web , the new strain of ransomware targets Linux-powered websites and servers by encrypting MySQL, Apache, and home/root folders associated with the target site and asking for 1 Bitcoin ( ~ $300 ) to decrypt the files. The ransomware threat is delivered to the target website through known vulnerabilities in website plugins or third-party software. Must Read: FBI Suggests Ransomware Victims — 'Just Pay th...

Cyber threats didn’t slow down last week—and attackers are getting smarter. We’re seeing malware hidden in virtual machines, side-channel leaks exposing AI chats, and spyware quietly targeting Android devices in the wild. But that’s just the surface. From sleeper logic bombs to a fresh alliance between major threat groups, this week’s roundup highlights a clear shift: cybercrime is evolving fast, and the lines between technical stealth and strategic coordination are blurring. It’s worth your time. Every story here is about real risks that your team needs to know about right now. Read the whole recap. ⚡ Threat of the Week Curly COMrades Abuses Hyper-V to Hide Malware in Linux VMs — Curly COMrades, a threat actor supporting Russia's geopolitical interests, has been observed abusing Microsoft's Hyper-V hypervisor in compromised Windows machines to create a hidden Alpine Linux-based virtual machine and deploy malicious payloads. This method allows the malware to run completel...

Security researchers have discovered an interesting piece of malware that infects systems with either a cryptocurrency miner or ransomware, depending upon their configurations to decide which of the two schemes could be more profitable. While ransomware is a type of malware that locks your computer and prevents you from accessing the encrypted data until you pay a ransom to get the decryption key required to decrypt your files, cryptocurrency miners utilize infected system's CPU power to mine digital currencies . Both ransomware and cryptocurrency mining-based attacks have been the top threats so far this year and share many similarities such as both are non-sophisticated attacks, carried out for money against non-targeted users, and involve digital currency. However, since locking a computer for ransom doesn't always guarantee a payback in case victims have nothing essential to losing, in past months cybercriminals have shifted more towards fraudulent cryptocurrency ...
