Brute forcing on secured shell servers emphasising the role of cyber forensics - a quali-quantitative study.

BACKGROUND: Increasing numbers of cyber attacks threaten us personally and professionally. Cyber crimes include obtaining sensitive information (medical or financial) but may extend to organising heinous crimes including murders and aggravated sexual assaults. A major vector of cyber crimes is brute force attacks on secured shell servers. AIM OF STUDY: This research highlights the prevalence of the intensity of brute force attacks on secured shell servers via quali-quantitative analysis of cyber attacks. METHODOLOGY: The brute force attacks were recorded over a period of 20 days with the help of logs taken from five dedicated servers installed in a production environment. RESULTS: There were a minimum of 6470 and maximum of 22,715 attacks on a server per day. The total number of attacks on all the servers during the study period was 1,065,920. The brute force attacks were mainly targeted at the service network accounts. CONCLUSION: Growth of the field of cyber forensics is the optimal solution to prevent the malicious use of internet services and the commissioning of crimes by this means.

Glass table tops: An unusual source of lethal domestic injury.

A 42-year-old woman who fell through a glass tabletop had her lower back pierced by a long shard of glass. She rapidly exsanguinated. At autopsy, a single penetrating wound was present in her left lower back, with complete transection of her left kidney and a 3.5 L haematoperitoneum. Death was due to exsanguination following accidental transection of the left kidney by a penetrating glass injury of the lower back. Glass-topped tables are a well-recognised source of injury in a domestic setting There are far more non-lethal than lethal injuries, many of which involve children. Quite long shards may remain undetected in wounds for considerable amounts of time. Non-tempered glass is a particular risk for breakage. Glass-topped tables should not be used as substitutes for chairs, particularly in overweight or obese individuals.

Timing of death of a dead born foetus determined at medico-legal autopsy refuted the allegation of medical negligence.

The case concerns a dead newborn. The family alleged that his death was due to delay in delivery by the attending doctors. Medico-legal autopsy was performed three days later which showed maceration changes suggestive of the foetus lying dead-in-utero for about 24 h which prima facie refuted the allegation of negligence.

An unusual patterned injury from homicidal craniocerebral impalement with a metal chair leg.

A 26-year-old young man died shortly after he had suffered craniocerebral impalement from a metal chair leg during an affray at an airport bar. At autopsy a 25 mm diameter circular wound was present in the left parietal region with protruding brain tissue. Death was due to craniocerebral trauma from a penetrating injury to the head. Examination of the chair used in the assault showed a metal chair with smeared blood on the front right leg that matched the blood group of the decedent. The fatal wound had been inflicted by the assailant with the victim leaning forward while kneeling on the floor. The assault had produced an unusual circular patterned defect in the left parietal bone with dimensions corresponding to the chair leg. The location of the defect and the use of a chair leg were two very unusual features in this homicide.

Fatal bleeding from a laceration of superficial temporal artery: A rare case.

We report a case of a 34-year-old drunken male, who was found dead in his apartment. On scene inspection, the deceased body was found in the sitting position on a chair, and a massive arterial blood pattern was observed at the scene. First responders and the coroner visited the scene considered this case as a criminally suspicious due to arterial blood pattern on walls and excessive blood pool at the scene. At autopsy, a laceration was present on the left side of the scalp with an underlying transection of the left superficial temporalis artery. Subsequent histological examination of the arterial section established its transection and cellular response to injury. After careful perusal of CCTV camera footages, pre-autopsy CT, macroscopic examination of injury, histological examination of the transected artery, and toxicological analysis report, cause of death was given as exsanguination due to laceration of a superficial temporal artery following blunt force head trauma. The manner of death was accidental. Although it is not uncommon to see deaths of alcoholics following scalp trauma, the peculiarity of this case lies in the fact that no evidence of fatal accidental superficial temporal artery has ever been reported in the forensic literature. We also suggest that a thorough analysis of history, circumstances, and histologic examination, even of a transacted artery can provide medicolegal relevant data.

Post-mortem CT with macroscopic and microscopic correlation in a case of sudden death due to systemic sarcoidosis.

We report a case of sudden death due to systemic sarcoidosis in a fifty-four year old male who was reportedly healthy. A computerized tomography (CT) scan was performed before the autopsy. It showed cardiomegaly with hilar and abdominal lymphadenopathy. The autopsy showed pale yellow plaque deposition on the heart surface which was infiltrating the myocardium. Histological examination of the heart, lungs, liver, and spleen showed extensive sarcoid granulomata which helped in establishing the cause of death.

Request for euthanasia in the suicide note of a planned suicide.

This case is of a suicide victim who purchased various drugs online using forged prescriptions after detailed research about the drugs to commit suicide. He left a suicide note giving details of his suicide methods and the reasons for it. He also denied any treatment and asked for euthanasia if he survived and remained in a vegetative state.

Rare gripping object in electrocution: Cadaveric spasm at its best.

Cadaveric spasm causes instantaneous rigor without preceding post-mortem flaccidity. The precise pathophysiological basis of this phenomenon is still unknown. We report a case of accidental electrocution where the deceased was found dead with a metallic water supply pipe of a motor booster pump firmly gripped in his hand. In this report, we review the literature and consider the mechanisms that may cause this phenomenon.

Deaths Due to Accidental Air Conditioner Compressor Explosion: A Case Series.

In an air-conditioning system, the compressor is a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. The explosion of an air conditioner (AC) compressor is an uncommon event, and immediate death resulted from the blast effect is not reported in forensic literature. We report three such cases in which young AC mechanics were killed on the spot due to compressor blast, while repairing the domestic split AC unit. The autopsy findings, the circumstances leading to the explosion of the compressor, are discussed in this study.

Intracranial penetrating injury by screw driver: a case report and review of literature.

Penetrating injury to the head, with the exception of missile injuries is rare owing to thick calvarium. Orbital and temporal areas are comparatively vulnerable to penetrating injuries, due to their relative thinness. A case is presented in which a man killed his wife by forcefully thrusting a screw driver into her cranial cavity. The deceased presented to the hospital with the screw driver embedded in her head. She was declared as 'brought dead on arrival' at the emergency of the hospital. Pre-autopsy plain radiography and Computed Tomography (CT) of the head were done to assess the extent of brain damage. The peculiarity of this case lies in the fact that screw driver as a stabbing weapon in the head is very rarely used. In such cases, there is a need to perform radiography and CT with the weapon in-situ for better interpretation on injuries. In this paper role of radiography and CT in intra cranial penetration is discussed with review of literature.
