Security researchers have recently uncovered a cyber espionage group targeting aerospace, defence and energy organisations in the United States, Saudi Arabia and South Korea. According to the latest research published Wednesday by US security firm FireEye, an Iranian hacking group that it calls Advanced Persistent Threat 33 (or APT33) has been targeting critical infrastructure, energy and military sectors since at least 2013 as part of a massive cyber-espionage operation to gather intelligence and steal trade secrets. The security firm also says it has evidence that APT33 works on behalf of Iran's government. FireEye researchers have spotted cyber attacks aimed by APT33 since at least May 2016 and found that the group has successfully targeted aviation sector—both military and commercial—as well as organisations in the energy sector with a link to petrochemical. The APT33 victims include a U.S. firm in the aerospace sector, a Saudi Arabian business conglomerate with avi

Air-gapped computers that are isolated from the Internet and physically separated from local networks are believed to be the most secure computers which are difficult to infiltrate. However, these networks have been a regular target in recent years for researchers, who have been trying to demonstrate every possible attack scenarios that could compromise the security of such isolated networks. Security researchers from Ben-Gurion University in Israel have previously demonstrated several ways to extract sensitive information from air-gapped computers. Now, the same University researchers have discovered another way to steal confidential information from air-gapped computers – this time with the help of infrared-equipped CCTV cameras that are used for night vision. Researchers have developed a new attack scenario, dubbed aIR-Jumper, which includes an infected air-gapped computer (from which data needs to be stolen) and an infected CCTV network (that has at least one CCTV insta

The  ransomware industry surged in 2023  as it saw an alarming 55.5% increase in victims worldwide, reaching a staggering 5,070.  But 2024 is starting off showing a very different picture.  While the numbers skyrocketed in Q4 2023 with 1309 cases, in Q1 2024, the ransomware industry was down to 1,048 cases. This is a 22% decrease in ransomware attacks compared to Q4 2023. Figure 1: Victims per quarter There could be several reasons for this significant drop.  Reason 1: The Law Enforcement Intervention Firstly, law enforcement has upped the ante in 2024 with actions against both LockBit and ALPHV. The LockBit Arrests In February, an international operation named "Operation Cronos" culminated in the arrest of at least three associates of the infamous LockBit ransomware syndicate in Poland and Ukraine.  Law enforcement from multiple countries collaborated to take down LockBit's infrastructure. This included seizing their dark web domains and gaining access to their backend sys

Viacom—the popular entertainment and media company that owns Paramount Pictures, Comedy Central, MTV, and hundreds of other properties—has exposed the keys to its kingdom on an unsecured Amazon S3 server. A security researcher working for California-based cyber resiliency firm UpGuard has recently discovered a wide-open, public-facing misconfigured Amazon Web Server S3 cloud storage bucket containing roughly a gigabyte's worth of credentials and configuration files for the backend of dozens of Viacom properties. These exposed credentials discovered by UpGuard researcher Chris Vickery would have been enough for hackers to take down Viacom's internal IT infrastructure and internet presence, allowing them to access cloud servers belonging to MTV, Paramount Pictures and Nickelodeon. Among the data exposed in the leak was Viacom's master key to its Amazon Web Services account, and the credentials required to build and maintain Viacom servers across its many subsidiarie

Researchers have been warning for years about critical issues with the Signaling System 7 (SS7) that could allow hackers to listen in private phone calls and read text messages on a potentially vast scale, despite the most advanced encryption used by cellular networks. Despite fixes being available for years, the global cellular networks have consistently been ignoring this serious issue, saying that the exploitation of the SS7 weaknesses requires significant technical and financial investment, so is a very low risk for people. However, earlier this year we saw a real-world attacks, hackers utilised this designing flaw in SS7 to drain victims' bank accounts by intercepting two-factor authentication code (one-time passcode, or OTP) sent by banks to their customers and redirecting it to themselves. If that incident wasn't enough for the global telecoms networks to consider fixing the flaws, white hat hackers from Positive Technologies now demonstrated how cybercriminals

The Recent discoveries of dangerous variants of the Android banking Trojan families, including Faketoken , Svpeng , and BankBot , present a significant threat to online users who may have their login credentials and valuable personal data stolen. Security researchers from SfyLabs have now discovered a new Android banking Trojan that is being rented on many dark websites for $500 per month, SfyLabs' researcher Han Sahin told The Hacker News. Dubbed Red Alert 2.0 , the Android banking malware has been fully written from scratch, unlike other banking trojans, such as BankBot and ExoBot, which were evolved from the leaked source code of older trojans. The Red Alert banking malware has been distributed via many online hacking forums since last few months, and its creators have continuously been updating the malware to add new functionalities in an effort to make it a dangerous threat to potential victims.
