An Overview Of Sideloading In Cybersecurity
By Tom Seest
At BestCybersecurityNews, we help young learners and seniors learn more about cybersecurity.
Apple’s Security Chief believes allowing sideloading on iPhone would create an “open invitation for cybercriminals” due to removing protections against accessing proprietary hardware elements and non-public operating system functions.
Threat actors exploit weaknesses in computer networks to gain illicit access and privileges that they exploit for malicious reasons, which often leads to full-scale infections that threaten essential business processes, databases, and digital operations.

While it can be challenging to prevent attackers from employing social engineering techniques to take advantage of human vulnerabilities, organizations can help their employees combat this tactic with security awareness training. Such courses should demonstrate how social engineering techniques can be used to compromise sensitive data or devices.
Furthermore, businesses should train employees how to recognize red flags in communications that may be suspicious. For instance, an offer that seems too good to be true or an attachment with an unclear name sent at an odd time should raise concerns.
At security company RSA in 2011, a well-known example of a successful social engineering attack was their 2011 data breach. Here, attackers persuaded employees to download a fake update with malicious backdoor code, allowing attackers to steal confidential data.
Social engineering techniques can also be employed to download and install sideloaded malware onto devices. Attackers could attempt to trick users into downloading fake Adobe Flash updates by masquerading as legitimate vendors or offering free file hosting services, then using these updates to install malicious DLLs, which give the attacker control of their devices.
Dynamic-link Library (DLL) side-loading can be found in many attack kits and takes advantage of applications’ tendencies to store DLL files in similar locations to where Windows loads them, enabling attackers to place a fake DLL into this same directory and have it executed with similar effects as an original one.
Defenders can reduce this threat by employing detection and response tools like Bitdefender GravityZone to detect DLL side-loading attacks. Furthermore, they should only download applications from trusted sources and limit user rights with Group Policy in order to prevent non-system administrators from downloading PUPs onto corporate devices.
Businesses reliant on third-party applications for core operations face serious risks from sideloading threats that rely on third-party apps; they could compromise essential services, databases, and digital processes which are essential to their ability to function, leading them to be locked out from accessing their own data unless they pay ransom fees.

Sideloading has been used by cybercriminals to gain entry to devices and target their victims. Applications downloaded from third parties often lack adequate security testing and may contain malicious software, leaving users vulnerable to infections such as malware, ransomware, and data breaches.
Many apps are acquired through social engineering techniques such as phishing emails, popup ads, and fake download links; others may appear legitimate on search results pages. They can bypass security measures through DLL side-loading exploitation which has become a key vulnerability exploited by attackers in cyberattacks.
Threat actors take advantage of Microsoft Windows applications‘ use of DLLs by exploiting an exploit in its design. An attacker gains privileges when running the DLL through an application and executes code on their device; DLL sideloading attacks are hard to detect for organizations that rely solely on antivirus or antimalware solutions; more advanced detection capabilities with real-time analysis, advanced tools, and threat data may be required in order to uncover them.
App stores offer several safeguards against malware to make it hard for any apps containing harmful software to slip past them, including approval processes and reviews after an app has been published and periodic scans of content. Unfortunately, these systems can sometimes be bypassed using social engineering tactics to dupe users into downloading malware from third-party sources – including unofficial versions of popular programs – like this unofficial download link.
CISOs should combine technical controls with user awareness training in order to mitigate the risks of sideloaded applications. They can establish policies limiting user rights and requiring software downloads only from official sites or app stores, as well as whitelists via application control platforms – this helps eliminate risks from cybercriminal infection such as malware infections, ransomware attacks, and other threats that could compromise databases, digital processes or even impede business operations.

Malware is an invaluable weapon used by attackers to gain entry and compromise systems. Cybercriminals employ it to steal credentials, encrypt data, disrupt core computing functions, spy on activity, and spy on activity. Malware typically enters systems by exploiting vulnerabilities on target computers which allow attackers to exploit vulnerabilities that then allow the malware to cause irreparable harm either directly to victims or businesses.
Attackers frequently utilize DLL (Dynamic Link Library) sideloading attacks as an effective method for sideloading malware onto systems. These attacks take advantage of how Windows searches for DLL files that an executable needs, placing a malicious DLL with the same name as its legitimate requirement in its directory before starting up the executable and prioritizing this local malicious DLL over one from system folders and thus initiating an attack. DLL side-loading allows attackers to gain persistence and bypass defenses that rely on search order hijacking as an effective protection strategy.
Attackers frequently utilize DLL side-loading by planting an executable that sideloads malicious second-stage payload. This technique enables attackers to exploit various software, as the signed executable often bypasses security solutions like application control policies and basic scanning tools.
X-Force has observed threat actors using various complex variations of this strategy to deploy various types of malware. For instance, APT hackers known as Dragon Breath and Golden Eye Dog are exploiting trojanized Telegram, LetsVPN, and WhatsApp mobile applications on mobile phones to sideload a second-stage loader DLL that drops other malicious tools, including ransomware payloads.
Defenders can utilize detection and response tools such as Bitdefender GravityZone that monitor for DLL side-loading techniques. Organizations may also employ data collection utilities that profile endpoints to collect metadata about possible DLL side-loading exploits such as internal names, hash values, and program execution artifacts, such as SideLoadHunter from X-Force Research Team which examines endpoints to detect any DLL and executable files located in user profiles, System32 or SysWow64 to identify possible side-loading exploits; such X-Force Research Team offers this free utility to do just this task – providing organizations with deeper analysis opportunities than ever before!

Attackers using passive exploitation techniques are adept at breaking into systems and networks without directly interfering with them. Active attacks – which modify data on an attacked system or intercept it in transit between target systems – involve altering these elements directly; passive attackers observe and gather information about an attack victim for later use – before employing this knowledge to launch active attacks against their targets.
Passive exploits take advantage of how applications search for libraries by using dynamic-link library (DLL) search order hijacking. Attackers place malicious libraries within folders where vulnerable applications look for DLLs that look for that library – when launched by victims, they load it and execute its payload. This technique may lead to privilege escalation as its contents get loaded and executed with administrative or SYSTEM rights; additionally, it enables persistence as replacing libraries hide their malicious payload from other software running on the same device.
DLL sideloading can be hard for cybersecurity teams to detect, making it a popular method of spreading malware in today’s digital landscape. Depending on its payload, this may result in businesses being locked out until paying ransom or seeing confidential data leakage occur.
As part of an overall approach to counter DLL sideloading threats, it’s best to restrict apps from being downloaded and installed from vendor sites or app stores; additionally, corporate devices should only allow access to applications downloaded directly from those sources or app stores; additionally, it is beneficial for companies and software vendors to work together to enhance security by including protections against DLL sideloading and other threats in their installers.
Apart from these measures, a comprehensive cyber defense posture should also be established that integrates psychological warfare and computer network operations, along with military deception tactics and security operations. This approach ensures that organizations are ready for any threat, including passive exploit attacks on mobile devices. As cyberattacks targeting mobile devices continue to increase exponentially, understanding and implementing a multi-layered strategy that safeguards enterprise is becoming ever more crucial.
