The attackers continue to use the HyperBro backdoor which is often loaded using the dynamic-link library (DLL) side-loading technique. The binary, which has the default name vf_host.exe, is usually renamed by the attackers in order to masquerade as a more innocuous file. ” reads the report published by the experts.
Like the sample analyzed by Cyberreason, the Spyder Loader sample analyzed by Symantec uses the CryptoPP C++ library. To prevent analysis, the malware also cleans up created artifacts, overwriting the content of the dropped wlbsctrl.dll file before deleting it. . ” continues the report. Pierluigi Paganini.
The name KilllSomeOne comes from the phrase ‘KilllSomeOne’ used in the DLL side-loading attacks, the group is using poorly-written English messages relating to political subjects. . Dynamic-link library (DLL) side-loading takes advantage of how Microsoft Windows applications handle DLL files. Pierluigi Paganini.
Once the malware has infected a system drops two plain text files, one is a ransom note called “_FILES_ENCRYPTED_README.txt,” which gives information to the victim on what has happened and instruction to pay the ransom. Like other ransomware, the operators allow victims to unlock a file for free. Pierluigi Paganini.

dll: Windows legitimate DLL for runtime dependencies – MICROSOFT® C RUNTIME LIBRARY. dll: Windows legitimate DLL for runtime dependencies – MICROSOFT® C RUNTIME LIBRARY. Usually, executables using the side-by-side feature will have these resources located in the embedded manifest file. exe8CBB75FEBFB4B0B7C3B6D3613386220C.
“The archive contains two malicious DLL libraries as well as two legitimate executables that sideload the DLL files. We found multiple archives like this with filenames of government entities in Myanmar, for example “COVID-19 Case 12-11-2020(MOTC).rar” ” reads the analysis published by Kaspersky.
“Unfortunately this happened because of an upstream library we use became infected.” ” The trojanized 3CXDesktopApp is the first stage in a multi-stage attack chain, the installers retrieve ICO files appended with base64 data from Github and ultimately leading to the deployment of 3rd stage information stealer.
Since the beginning of the year, security firms observed a new intense ransomware campaign spreading the Shade ransomware. Between January and February, a new, intense, ransomware campaign has been observed by many security firms. It contains a russian speaking JavaScript filenamed “«??? «??? «?????????» ??????????? ??????”,
This approach allows the attacker to continuously update and eliminates reliance on fixed filenames.” The second-stage malware, UpdatTask.dll , is a dynamic-link library (DLL) written in C++ that includes two export functions, DllEntryPoint and Entry. ” continues the report.
The spear-phishing message appears as a benign conversation lure masquerading as a senior fellow with the Royal United Services Institute (RUSI) to the public media contact for a nuclear security expert at a US-based think tank focused on foreign affairs.

There, the classical security notice informs us that macros are contained in the document and are disabled. The macro contained inside the document is quite minimal and does not contain dead code or other anti-analysis technique, a part of the random looking variable naming. Table 1: Static information about the sample. Code Snippet 4.
Security and access controls. Check-in and check-out are very similar to how a library works – when a book is checked out, nobody else has access to it until it is checked back in. This feature also reduces the need to store multiple copies and versions, and their associated naming conventions, in order to retain a document’s history.
The malware encrypts all the files whose extension is not present in the list. Figure 4: Content of “key” file contained in “C:ProgramData”. During the encryption phase, JSWorm writes a suspicious filenamed “key.Infection_ID.JSWRM” in “C:ProgramData”.It It contains the AES key used to encrypt the files.
However, in this new release, two DLL files are distributed. VBS file leverages the Windows rundll32 library to inject the first DLL into memory (P-14-7.dll), Figure 6: Deofuscated VBS file – Lampion trojan July 2020. LNK files from the Windows startup folder. VBS files from the Windows startup folder.
On April 19 2019 researchers at Chronicle, a security company owned by Google’s parent company, Alphabet, have examined the leaked tools , exfiltrated the past week on a Telegram channel, and confirmed that they are indeed the same ones used by the OilRig attackers. The panel reads those files and implements stats and actions.
A randomly named folder is created in the Windows AppData directory that will keep the malicious files. Figure 15: Some operations are performed, such as create folders on AppData and setting the default process security level with VBScript – (3/5). Two files are obtained from 2 AWS S3 buckets. At the moment, the file 0.zip
Limited Sorting and Filtering : Users can only sort and filter files based on basic attributes like name and date within a folder, restricting efficient data retrieval. Ineffective Search Capabilities : Without additional metadata, searches are limited to filenames or basic content, making it difficult to perform targeted searches.
Since then, much has been learned about the tactics, techniques, and procedures (TTPs) deployed and what steps organizations are taking to harden their network and application security. Former Department of Homeland Security (DHS) officials noted “this could be an extremely serious breach of security.” federal agencies.
This operation is similar to the threat group’s August 2018 campaign , using compromised university resources to send library-themed phishing emails.” The hackers registered at least 20 new domain names through the Freenom domain provider that offers free top-level domain names. Pierluigi Paganini.
Emotet is a modular malware, its operators could develop new Dynamic Link Libraries to update its capabilities. Recently, the Cybersecurity and Infrastructure Security Agency (CISA) issued an alert to warn of a surge of Emotet attacks that have targeted multiple state and local governments in the U.S. since August. Mail: XXXXXXXXX.
“The emails all contained a malicious Rich Text Format (RTF) phishing lure with the filename 20200323- sitrep -63- covid -19. ” The messages use a weaponized rich text format (RTF) attachment that exploits the CVE-2012-0158 buffer overflow in Microsoft’s ListView / TreeView ActiveX controls in MSCOMCTL.OCX library.
The second layer of Python code decodes and loads to memory the main RAT and the imported libraries. The new infection chain starts by including just one LNK file in the ZIP archive attached to spear-phishing messages. The post Evilnum APT used Python-based RAT PyVil in recent attacks appeared first on Security Affairs.
“In addition, when copying files, Winnti Loader changes the filename to one consisting of an underscore and 5-9 alphabetic characters (e.g., “_syFig.dll” or “_TcsTgyqmk.dll”). The Winnti Loader then dynamically loads the copied libraries and deletes the copied files once the loading is complete.”
