New insight into ransomware attacks show that cyber attacks are a top concern for organizations – with many not aware they were a victim until after the attack. According to Arctic Wolf’s The State of Cybersecurity: 2024 Trends Report, 91% of reported ransomware attacks included a data exfiltration effort. This is far more than the sub-80% numbers we’ve seen from the Coveware quarterly reports we cover.

Top tips is a weekly column where we highlight what’s trending in the tech world today and list ways to explore these trends. This week, we’re looking at three signs that your device may be infected with crypto malware. Has your computer been acting strange lately? Has the performance tanked out of nowhere, and are you experiencing overheating issues even though you’re not running any particularly demanding tasks at the moment?

From late 2023 and into 2024, the ransomware ecosystem has become more diverse than ever, with an ever-expanding cast of extortion groups. Established players continue to compromise large companies globally, while smaller, newer groups are breaking into the scene with increasing frequency. From January to mid-May 2024 alone, 22 new ransomware groups emerged. In comparison, only 22 groups emerged during the entire two-and-a-half-year period between January 2018 and August 2020.

As we near the halfway point of 2024, it is apparent that the epidemic of extortionary cyber attacks will continue unabated into the foreseeable future. Now more than ever, I believe that until organizations adopt cultural approaches to cybersecurity, breaches will continue to wreak havoc on companies and industries. But why is this? There are far too many reasons to enumerate here, but in my experience the biggest factors are.

Believing that your organization is immune to ransomware is wishful thinking at best. Despite advancements in enterprise cybersecurity, the reality is that breaches are not a matter of if but when. Even the most sophisticated preventative measures can be circumvented by determined and resourceful cybercriminals, whose methods are constantly evolving. The fallout from a successful ransomware attack can be catastrophic.

The Foresiet Threat Intelligence Team has recently conducted an in-depth analysis of an Android malware Trojan masquerading as the "VAHAN PARIVAHAN.apk" application. This trojan poses a significant threat to users by leveraging a backdoor, utilizing the Telegram API bot, and exploiting the services of GoDaddy.com LLC and Mark Monitor Inc. In this blog, we delve into the specifics of this malware, including its technical details, behavior, and potential impact on users.

Attackers are continually developing sophisticated techniques to bypass defensive measures and achieve their goals. One highly effective approach involves exploiting the operating system's native features to evade detection and ensure compatibility. In the realm of ransomware threats, this can be seen in the use of the cryptographic functions within ADVAPI32.dll, such as CryptAcquireContextA, CryptEncrypt, and CryptDecrypt.
